+# Code Quality Review
+
+## Findings
+
+### High: GitHub bot support is wired only to the standard GitHub App despite lite handling elsewhere
+
+- **Affected files/functions:** `apps/web/src/lib/bot.ts` (`githubAdapter` initialization), `apps/web/src/app/api/webhooks/github/route.ts`, `apps/web/src/app/api/webhooks/github-lite/route.ts`, `apps/web/src/app/github/link/route.ts`, `apps/web/src/app/api/integrations/github/callback/route.ts`
+- **Issue:** The bot adapter is always created from `getGitHubAppCredentials('standard')`, and only `/api/webhooks/github` forwards requests to `bot.webhooks.github`. Account linking explicitly supports `integration.github_app_type ?? 'standard'`, including `lite`.
+- **Risk:** Users can link through a lite integration, but lite webhooks never reach the chat adapter and the adapter has no lite credentials. Mention ingestion and linking have inconsistent app-type support.
+- **Recommended fix:** Either make GitHub bot support standard-only and block/link-message lite integrations, or instantiate/route a separate GitHub adapter for lite credentials. Mirror standard bot routing in `apps/web/src/app/api/webhooks/github-lite/route.ts` or add an adapter-selection layer keyed by `github_app_type`.
+
+### Medium: GitHub context API failures can fail the entire bot run
+
+- **Affected files/functions:** `apps/web/src/lib/bot/conversation-context.ts` (`getGitHubConversationContext`), `apps/web/src/lib/bot/agent-runner.ts` (`buildSystemPrompt`)
+- **Issue:** `getGitHubConversationContext` calls `issues.get`, `issues.listComments`, and `pulls.listReviewComments` inside a single `Promise.all` without local error handling.
+- **Risk:** A GitHub outage, rate limit, deleted issue/PR, missing permission, or malformed thread ID can reject prompt construction and prevent any bot response, even though reduced context would be enough to answer.
+- **Recommended fix:** Treat GitHub context as best-effort. Use `Promise.allSettled` or local catches, capture errors with repository/thread metadata, and return partial context or an empty string.
+
+### Medium: Webhook handler imports initialize the full bot and adapters as a side effect
+
+- **Affected files/functions:** `apps/web/src/lib/integrations/platforms/github/webhook-handlers/installation-handler.ts`, `apps/web/src/lib/integrations/platforms/github/webhook-handler.ts`, `apps/web/src/lib/bot.ts`
+- **Issue:** `installation-handler.ts` imports `bot` to call `bot.initialize()` and access bot state for `unlinkTeamKiloUsers`. Importing the generic GitHub webhook handler now initializes the full bot, Slack adapter, GitHub adapter, and standard GitHub credentials.
+- **Risk:** This couples integration cleanup to chat runtime initialization and can break webhook handling if bot configuration is missing. It also increases side effects and dependency-cycle risk.
+- **Recommended fix:** Avoid importing `bot` from integration handlers. `unlinkTeamKiloUsers` only needs a state adapter; create or inject chat state from a small state module, or move cleanup into a bot-owned path.
+
+### Medium: All standard GitHub webhooks are forwarded to the chat adapter
+
+- **Affected files/functions:** `apps/web/src/app/api/webhooks/github/route.ts`
+- **Issue:** The route schedules `bot.webhooks.github(...)` for every standard GitHub webhook before the legacy handler determines event type/action. Tests lock in forwarding `installation` and `pull_request` events, even though the bot needs mention-capable comment events.
+- **Risk:** Unnecessary work, noisy logs, doubled signature/body parsing, and broader future behavior if the adapter starts handling more event types.
+- **Recommended fix:** Filter before forwarding. At minimum gate on `x-github-event` for `issue_comment` and `pull_request_review_comment`, and ideally require `action === 'created'`.
+
+### Medium: GitHub link routes duplicate unsafe HTML response construction
+
+- **Affected files/functions:** `apps/web/src/app/github/link/route.ts` (`errorPage`), `apps/web/src/app/api/integrations/github/callback/route.ts` (`htmlPage`, `handleGitHubBotLinkCallback`)
+- **Issue:** Two routes manually build full HTML pages with duplicated inline styles and string interpolation. The callback interpolates `githubUser.login` directly into HTML.
+- **Risk:** GitHub logins are constrained today, but the helper is general-purpose and easy to reuse unsafely later. Duplicated page construction makes escaping and response behavior harder to keep consistent.
+- **Recommended fix:** Centralize minimal HTML responses in a shared helper that escapes interpolated text by default and only allows explicitly trusted HTML fragments.
+
+### Low: Token/state verification relies on `as` casts instead of schema validation
+
+- **Affected files/functions:** `apps/web/src/lib/bot/github-link-token.ts` (`verifyGitHubLinkToken`), `apps/web/src/lib/bot/github-link-state.ts` (`verifyGitHubBotLinkState`)
+- **Issue:** Both verifiers parse JSON as `Partial<...>` using `as`, then manually check fields. This conflicts with repo guidance to avoid casts when possible.
+- **Risk:** Manual validation can drift from payload types as fields are added.
+- **Recommended fix:** Define Zod schemas for both payloads and parse decoded JSON with `safeParse`, returning `null` on validation failure.
+
+### Low: Slack-specific documentation URL is returned for GitHub
+
+- **Affected files/functions:** `apps/web/src/lib/bot/platform-helpers.ts` (`getBotDocumentationUrl`), `apps/web/src/lib/bot/platform-helpers.test.ts`
+- **Issue:** `getBotDocumentationUrl(PLATFORM.GITHUB)` returns the Slack documentation URL, and the test locks in that behavior.
+- **Risk:** GitHub users asking for help receive Slack-specific docs.
+- **Recommended fix:** Add a GitHub-specific docs URL or a platform-neutral bot docs URL. Update the test to assert the intended fallback.
+
+### Low: GitHub platform identity extraction remains coupled to Slack-specific cast patterns
+
+- **Affected files/functions:** `apps/web/src/lib/bot/platform-helpers.ts` (`getPlatformIdentity`)
+- **Issue:** The Slack branch still casts `message as Message<SlackEvent>` to call `getSlackTeamId`. This helper is now the cross-platform identity boundary.
+- **Risk:** As more adapters are added, it becomes easier to access raw payloads with the wrong shape.
+- **Recommended fix:** Add type guards or delegate to adapter-specific identity extractors with typed inputs.
+
+### Low: Manual GitHub thread ID parsing is tightly coupled to adapter internals
+
+- **Affected files/functions:** `apps/web/src/lib/bot/conversation-context.ts` (`parseGitHubThreadId`, `getGitHubConversationContext`)
+- **Issue:** GitHub context depends on hard-coded thread ID formats such as `github:owner/repo:issue:number` and `github:owner/repo:number:rc:id`.
+- **Risk:** If `@chat-adapter/github` changes thread ID format, context silently disappears or fetches wrong coordinates.
+- **Recommended fix:** Prefer adapter-provided metadata/raw payload fields. If manual parsing is unavoidable, isolate it in a compatibility module with explicit tests and documentation.

+# Concurrency Review
+
+## Overall Behavior
+
+GitHub webhooks now take two paths from `apps/web/src/app/api/webhooks/github/route.ts`:
+
+1. The request body is read once and cloned.
+2. `bot.webhooks.github(...)` is scheduled in `after(...)` for the Chat SDK GitHub adapter.
+3. The existing `handleGitHubWebhook(...)` path still runs and returns the HTTP response.
+4. The Chat SDK adapter turns created GitHub issue comments, PR comments, or review comments into `Message`s and calls `chatBot.onNewMention(...)` in `apps/web/src/lib/bot.ts`.
+5. The bot resolves installation/user/integration state, creates a `bot_requests` row, refetches live GitHub context, runs the AI agent, and posts a reply.
+
+Shared state includes Chat SDK Redis/memory state, GitHub adapter installation cache, Kilo user links, `bot_requests`, live GitHub comments, and the legacy auto-fix state for PR review comments.
+
+## Findings
+
+### High: Rapid mentions in the same GitHub thread are silently dropped
+
+- **Affected files/functions:** `apps/web/src/lib/bot.ts`, `apps/web/src/app/api/webhooks/github/route.ts`, `apps/web/src/lib/bot/run.ts`
+- **Scenario:** Several users add `@kilocode-bot ...` comments quickly on the same issue, PR, or review thread. The Chat SDK `Chat` instance has no explicit concurrency option, so it appears to use the SDK default strategy: `drop`. The first message gets the per-thread lock; later messages on the same thread fail while the long AI run is active.
+- **Impact:** Later GitHub mentions are not queued and may receive no visible reply. GitHub still gets a successful webhook response, so users see a delivered comment but the bot appears to ignore them.
+- **Recommended fix:** Configure explicit queueing for GitHub bot work, with bounded queue size and TTL. Add tests simulating multiple comments on the same thread and assert later comments are queued, coalesced, or clearly acknowledged rather than silently dropped.
+
+### High: Different review comment threads on the same PR can run concurrently against the same branch
+
+- **Affected files/functions:** `apps/web/src/lib/bot.ts`, `apps/web/src/lib/bot/agent-runner.ts`, `apps/web/src/lib/bot/conversation-context.ts`, GitHub adapter thread IDs like `github:{owner}/{repo}:{prNumber}:rc:{commentId}`
+- **Scenario:** A reviewer mentions the bot on multiple line comments in the same PR. Each root review comment becomes a different Chat SDK thread ID because the ID includes the review comment ID. The SDK lock is per thread, so all runs can proceed concurrently.
+- **Impact:** Multiple Cloud Agent sessions may edit the same repository/PR branch at the same time, producing conflicting pushes, out-of-order replies, and confusing workflows.
+- **Recommended fix:** Add an application-level mutex/queue keyed by GitHub PR coordinates, such as `github-pr:{owner}/{repo}:{prNumber}`. Serialize code-changing runs per PR while optionally allowing read-only answers to proceed independently.
+
+### High: Chat SDK lock TTL can expire while a long AI run is still active
+
+- **Affected files/functions:** `apps/web/src/lib/bot.ts`, `apps/web/src/lib/bot/run.ts`, `apps/web/src/lib/bot/agent-runner.ts`
+- **Scenario:** The first GitHub mention starts a long AI/tool run. If the Chat SDK lock TTL expires before the handler finishes, a later mention can start a second run on the same thread.
+- **Impact:** Replies may be out of order, and multiple Cloud Agent sessions can run for what users perceive as one conversation.
+- **Recommended fix:** Add a long-lived application-level lock renewed until `processMessage(...)` finishes, or store an explicit active-run record that later comments queue behind or append to. Add a slow-handler test around the lock TTL boundary.
+
+### Medium: Live context fetch can include comments created after the triggering mention
+
+- **Affected files/functions:** `apps/web/src/lib/bot/conversation-context.ts`, `apps/web/src/lib/bot/agent-runner.ts`
+- **Scenario:** Comment A mentions the bot. Before A's run builds context, comments B and C are added. `getGitHubConversationContext(...)` refetches current issue/review comments and only filters out the trigger message by ID.
+- **Impact:** The run triggered by A can see B/C as prior context even though they happened later. If B/C were dropped by concurrency handling, they may still influence the prompt without being acknowledged.
+- **Recommended fix:** Filter fetched comments to `created_at <= triggerMessage.metadata.dateSent`. If queueing is enabled, pass queued/skipped comments explicitly as messages received while the previous run was active.
+
+### Medium: GitHub review-comment webhooks can be handled by two independent systems
+
+- **Affected files/functions:** `apps/web/src/app/api/webhooks/github/route.ts`, `apps/web/src/lib/integrations/platforms/github/webhook-handler.ts`, `apps/web/src/lib/integrations/platforms/github/webhook-handlers/pr-review-comment-handler.ts`, `apps/web/src/lib/auto-fix/application/webhook/review-comment-webhook-processor.ts`
+- **Scenario:** Every GitHub webhook is sent to the Chat SDK adapter in `after(...)`. Created `pull_request_review_comment` events are also routed to legacy auto-fix, which looks for `@kilo` plus fix/patch language.
+- **Impact:** A single review comment can spawn both a Chat bot run and an auto-fix ticket if mention aliases overlap or users include both command styles.
+- **Recommended fix:** Decide one owner for review-comment fix commands. Gate the Chat SDK path away from legacy auto-fix comments, or migrate legacy behavior behind the Chat adapter with shared idempotency.
+
+### Medium: `bot_requests` logging is not idempotent for duplicate platform message processing
+
+- **Affected files/functions:** `apps/web/src/lib/bot/request-logging.ts`, `packages/db/src/schema.ts`, `apps/web/src/lib/bot/run.ts`
+- **Scenario:** GitHub retries, serverless duplication, lock expiry, or process restart causes the same GitHub comment to be processed more than once outside the SDK dedupe window. `createBotRequest(...)` inserts a new row every time.
+- **Impact:** Duplicate bot runs and admin records can be created for one GitHub comment. If Redis is unavailable and memory state is used, dedupe is process-local and easier to bypass.
+- **Recommended fix:** Add a unique idempotency key for inbound bot messages, likely `(platform, platform_thread_id, platform_message_id)`, and use `insert ... on conflict` behavior.
+
+## Expected User Experience
+
+- Multiple mentions in the same issue/PR conversation are likely to process only the first mention while later mentions are dropped.
+- Multiple line-level review mentions on the same PR can run concurrently and race on the same branch.
+- Replies can be out of order when long runs overlap lock expiry or independent review-comment threads.
+- Context can include comments added after the trigger, so the bot may appear to respond to the wrong slice of the conversation.
+- Users will not get a clear queued/already-working response unless the handler implements one.
+
+The safest model is explicit idempotent queueing, with serialization at least per PR for code-changing work and clear treatment of skipped or coalesced comments.

+# General Review
+
+## Findings
+
+### High: GitHub review-comment mentions can be processed twice
+
+- **Affected files/functions:** `apps/web/src/app/api/webhooks/github/route.ts`, `apps/web/src/lib/integrations/platforms/github/webhook-handler.ts`
+- **Scenario/impact:** The route forwards every standard GitHub webhook to the Chat SDK adapter in `after(...)`, then also calls the legacy GitHub webhook handler. For `pull_request_review_comment.created`, the legacy path still calls `handlePRReviewComment(...)`, while the Chat SDK adapter may also turn the same mention into `onNewMention`. A single review-comment mention can trigger both legacy auto-fix and the new bot flow, causing duplicate agent runs, duplicate comments, conflicting side effects, and doubled model/API usage.
+- **Recommended fix:** Route each event to exactly one bot path. Either exclude `pull_request_review_comment` events from the Chat SDK adapter while legacy auto-fix remains active, or migrate that event fully to the Chat SDK adapter and disable the legacy mention path. Add a regression test that a review comment with a bot mention invokes only one processing path.
+
+### High: Lite GitHub app webhooks are not connected to the new bot adapter
+
+- **Affected files/functions:** `apps/web/src/app/api/webhooks/github-lite/route.ts`, `apps/web/src/lib/bot.ts`
+- **Scenario/impact:** The new GitHub adapter is configured only with standard app credentials, and only `/api/webhooks/github` forwards deliveries to `bot.webhooks.github(...)`. Lite installations still post to `/api/webhooks/github-lite`, which only calls the legacy integration handler. Mentions from repos installed through `github_app_type: 'lite'` will not reach the new bot handler, even though account-linking and context code try to support lite integrations.
+- **Recommended fix:** Add bot adapter handling for the lite webhook endpoint with lite credentials, or create a routing layer that can verify and process both standard and lite app deliveries. Add tests for `/api/webhooks/github-lite` proving an `issue_comment.created` mention reaches the bot adapter.
+
+### High: GitHub Cloud Agent session links may be invisible to users
+
+- **Affected files/functions:** `apps/web/src/lib/bot/agent-runner.ts`, `apps/web/src/lib/bot/run.ts`
+- **Scenario/impact:** When the bot starts a Cloud Agent session, `processMessage` suppresses the normal public final reply, and `postSessionLinkEphemeral(...)` is the only place that posts the session URL. That helper always uses `thread.postEphemeral(...)`, which is Slack-oriented and may be unsupported or ineffective for GitHub. Failures are caught and only logged, so a GitHub user can ask Kilo to start work, get no visible response, and have no way to open the created session from GitHub.
+- **Recommended fix:** Branch on `thread.adapter.name`: keep ephemeral cards for Slack, but post a normal GitHub reply with the session link or a safe handoff message for GitHub. If `postEphemeral` fails on platforms without ephemeral support, fall back to `thread.post(...)`. Add a GitHub-specific test for the session-start path.
+
+### Medium: GitHub context tags are not covered by the prompt-injection warning
+
+- **Affected files/functions:** `apps/web/src/lib/bot/conversation-context.ts`, `apps/web/src/lib/bot/agent-runner.ts`
+- **Scenario/impact:** GitHub issue descriptions, comments, review comments, and diff hunks are user/repository-controlled content, but they are inserted into tags the system prompt does not explicitly identify as untrusted. Malicious issue comments or PR descriptions can contain prompt-injection text that the model may treat as instructions.
+- **Recommended fix:** Update the system prompt to mark all GitHub context tags as untrusted, or wrap GitHub user-controlled content in the existing untrusted convention. Separate trusted metadata from untrusted bodies and add tests for the generated prompt warning.
+
+### Medium: GitHub API context fetch failures abort the entire bot run
+
+- **Affected files/functions:** `apps/web/src/lib/bot/conversation-context.ts`, `apps/web/src/lib/bot/agent-runner.ts`
+- **Scenario/impact:** `getGitHubConversationContext(...)` fetches the issue, issue comments, and review comments with `Promise.all(...)` and no local error handling. A transient GitHub error, rate limit, missing permission, deleted issue/PR, or unsupported thread ID shape can reject prompt construction and make the bot fail instead of answering with reduced context.
+- **Recommended fix:** Make GitHub context best-effort. Catch context-fetch errors, capture them with useful tags, and return minimal context containing the trigger message and thread coordinates. Prefer `Promise.allSettled(...)` so one failed auxiliary call does not discard all available context.
+
+### Medium: Public GitHub account-link links are not bound to the triggering GitHub user
+
+- **Affected files/functions:** `apps/web/src/lib/bot/link-account.tsx`, `apps/web/src/lib/bot/github-link-token.ts`, `apps/web/src/app/github/link/route.ts`
+- **Scenario/impact:** The public link posted in an issue/PR contains only the platform integration and installation ID. Any Kilo user who is a member of the owning organization can click someone else's visible link and complete OAuth for their own GitHub account. This likely does not hijack the original commenter because the callback links the OAuth-authenticated GitHub user ID, but it is an unintended enrollment path and can make public prompts misleading.
+- **Recommended fix:** Human-verify the intended policy. If the link should only be usable by the triggering GitHub user, include that GitHub user ID in the signed token/state and verify it against the OAuth-authenticated GitHub user. If any org member may self-link from any prompt, update copy and tests to make that explicit.

+# Cross-Platform State Leak Review
+
+## Overall Conclusion
+
+I did not find a confirmed direct Slack-to-GitHub identity leak in the normal happy path. The new code generally separates Slack and GitHub by platform:
+
+- Bot identity Redis keys include `platform` via `identity:${platform}:${teamId}:${userId}`.
+- Slack account linking still uses ephemeral `/api/chat/link-account` prompts.
+- GitHub account linking uses a separate public `/github/link` OAuth flow.
+- `getPlatformContext()` switches on `thread.adapter.name`, so Slack channel context is not intentionally included in GitHub prompts.
+- Slack uninstall cleanup and GitHub installation delete cleanup both pass the platform into `unlinkTeamKiloUsers()`.
+
+The main risks are places where GitHub state is selected or replayed using only shared identifiers such as installation ID or thread ID. These can cross boundaries if duplicate rows, corrupted bot request rows, stale tokens, or adapter bugs occur.
+
+## Findings
+
+### High: GitHub integration lookup is scoped only by installation ID, while duplicate installation rows may be possible
+
+- **Affected files/functions:** `apps/web/src/lib/bot/platform-helpers.ts` (`getPlatformIntegration`), `apps/web/src/lib/integrations/db/platform-integrations.ts` (`findIntegrationByInstallationId`), `apps/web/src/app/github/link/route.ts`, `apps/web/src/app/api/integrations/github/callback/route.ts`, `packages/db/src/schema.ts` (`platform_integrations`)
+- **Leak scenario:** Slack integrations have a global unique index on `(platform, platform_installation_id)`, but GitHub integrations appear to have owner-scoped unique indexes. `getPlatformIntegration(identity)` and `findIntegrationByInstallationId(PLATFORM.GITHUB, installationId)` query only by platform and installation ID, then use `.limit(1)`. The bot identity key is also only `identity:github:${installationId}:${githubUserId}`.
+- **What would happen:** If the same GitHub installation ID exists for multiple Kilo owners, a GitHub mention can resolve to an arbitrary integration row. GitHub issue context comes from the real installation, but repository lists, profile config, org ID, billing/ownership, and Cloud Agent context can come from the wrong Kilo owner.
+- **Impact:** Cross-tenant state leak across Kilo owners for GitHub bot requests, including possible wrong-owner Cloud Agent sessions.
+- **Recommended fix:** Prefer a global unique constraint for active GitHub installation IDs if one GitHub App installation belongs to exactly one Kilo owner. If duplicates are valid, carry `platformIntegrationId` through the GitHub adapter/linking flow and key bot identity by `platformIntegrationId`, not only installation ID. Replace installation-only lookups with exact integration lookups.
+- **Human verification:** Confirm whether duplicate active GitHub `platform_installation_id` rows are possible in production.
+
+### Medium: Bot session callbacks reconstruct the posting adapter from `platform_thread_id` without validating it matches the stored integration platform
+
+- **Affected files/functions:** `apps/web/src/app/api/internal/bot-session-callback/[botRequestId]/route.ts` (`POST`, `postBotThreadMessage`, `continueBotAgentAfterCallback`), `apps/web/src/lib/bot/run.ts`, `apps/web/src/lib/bot/request-logging.ts`
+- **Leak scenario:** `processLinkedMessage()` stores `platform: thread.adapter.name` and `platform_thread_id: thread.id`. The callback later loads `platformIntegration` from `platform_integration_id`, then reconstructs the destination with `bot.thread(requestRow.platform_thread_id)`. There is no assertion that `requestRow.platform`, `platformIntegration.platform`, and the reconstructed thread adapter all match.
+- **What would happen:** A corrupted or malformed bot request row could post a Slack-originated Cloud Agent result to a GitHub thread, or a GitHub-originated result through Slack context, while billing/logging/owner context comes from another platform.
+- **Impact:** Cross-platform callback leakage is possible if persisted bot request state becomes inconsistent. This is probably not externally reachable in the normal path, but the callback endpoint trusts persisted state too much.
+- **Recommended fix:** Before posting, assert `requestRow.platform === platformIntegration.platform`, `bot.thread(...).adapter.name === requestRow.platform`, and `bot.thread(...).adapter.name === platformIntegration.platform`. Fail closed and mark the bot request errored if values differ.
+
+### Medium: GitHub context fetch trusts repo coordinates from `thread.id` and does not validate them against the resolved integration
+
+- **Affected files/functions:** `apps/web/src/lib/bot/conversation-context.ts` (`parseGitHubThreadId`, `getGitHubConversationContext`)
+- **Leak scenario:** The bot parses owner/repo/issue from `thread.id`, generates an installation token from the resolved integration, and fetches issue/PR content without verifying the repo belongs to that integration's selected repositories.
+- **What would happen:** If a malformed thread ID is accepted, the bot can fetch context for any repository accessible to the installation token. The fetched content is injected into the prompt.
+- **Impact:** Repository-to-repository context leakage inside the same GitHub installation, or cross-owner leakage if combined with wrong integration lookup.
+- **Recommended fix:** Validate parsed `owner/repo` against `platformIntegration.repositories` before GitHub API calls. Prefer adapter-provided immutable webhook metadata over security-relevant parsing from `thread.id`.
+
+### Medium: Public GitHub link token and OAuth state are not bound tightly enough to one integration row
+
+- **Affected files/functions:** `apps/web/src/lib/bot/link-account.tsx` (`buildGitHubLinkUrl`), `apps/web/src/lib/bot/github-link-token.ts`, `apps/web/src/app/github/link/route.ts`, `apps/web/src/lib/bot/github-link-state.ts`, `apps/web/src/app/api/integrations/github/callback/route.ts`
+- **Leak scenario:** The public token contains `platformIntegrationId` and `installationId`. `/github/link` checks access to `platformIntegrationId`, but does not verify `verifiedToken.installationId === integration.platform_installation_id`. The OAuth state carries only `userId` and `installationId`, and the callback resolves the integration again by installation ID only.
+- **What would happen:** With stale/mismatched tokens or duplicate installation rows, the user can be authorized against one integration row and linked against another row selected by installation ID.
+- **Impact:** Account-link state can drift away from the integration row that produced the link prompt.
+- **Recommended fix:** In `/github/link`, reject tokens where `integration.platform !== 'github'` or installation IDs do not match. Include `platformIntegrationId` in OAuth state, load the same integration by ID in the callback, and use one-time link tokens for public comments.
+
+### Low: Cloud Agent `createdOnPlatform` is derived from `thread.id` instead of adapter identity
+
+- **Affected files/functions:** `apps/web/src/lib/bot/agent-runner.ts` (`runBotAgent`)
+- **Leak scenario:** `const chatPlatform = params.thread.id.split(':')[0];` is used while other code correctly uses `thread.adapter.name`.
+- **What would happen:** A malformed or unexpected thread ID could mislabel session metadata.
+- **Impact:** Mostly analytics/session attribution leakage now, but could become more serious if downstream logic later gates behavior on `createdOnPlatform`.
+- **Recommended fix:** Use `params.thread.adapter.name` and optionally assert known thread ID prefixes match the adapter.
+
+## Safeguards Observed
+
+- `apps/web/src/lib/redis-keys.ts` includes platform in bot identity keys, preventing direct Slack/GitHub key collisions.
+- `apps/web/src/app/api/chat/link-account/route.ts` rejects GitHub identities so public GitHub links cannot use the Slack reprocess flow.
+- `apps/web/src/lib/bot/conversation-context.ts` separates Slack and GitHub context builders by `thread.adapter.name`.
+- `apps/web/src/lib/bot/link-account.tsx` uses ephemeral prompts for Slack and public OAuth prompts for GitHub.
+- `apps/web/src/lib/integrations/platforms/github/webhook-handlers/installation-handler.ts` deletes GitHub bot identity links using `PLATFORM.GITHUB`, so it should not delete Slack links for a numerically identical team/installation ID.

+# Security Review
+
+## Findings
+
+### Critical: Indirect prompt injection from GitHub context can drive privileged Cloud Agent actions
+
+- **Affected files/functions:** `apps/web/src/lib/bot/conversation-context.ts` (`getGitHubConversationContext`, `formatGitHubItemBody`, `formatGitHubComment`, `formatGitHubReviewComment`), `apps/web/src/lib/bot/agent-runner.ts` (`buildSystemPrompt`, `runBotAgent`), `apps/web/src/lib/bot/tools/spawn-cloud-agent-session.ts` (`spawnCloudAgentSession`)
+- **Issue:** The PR adds GitHub issue/PR descriptions, existing issue comments, review-thread comments, and diff hunks directly into the bot system prompt. The existing safety instruction only marks `<user_message>` and `<cloud_agent_result>` as untrusted, but the new content is wrapped in `<github_description>`, `<github_comment>`, `<github_review_comment>`, and `<github_diff_hunk>`.
+- **Attack scenario:** An attacker who does not invoke the bot writes malicious instructions in a PR description, issue body, old issue comment, review comment, or code/diff hunk. A legitimate linked user later comments `@kilocode-bot fix this`. The bot fetches the attacker-controlled content as context and may follow instructions to spawn a Cloud Agent session, choose another repository, push changes, or reveal private context.
+- **Impact:** This escalates attacker influence from writing discussion/code content to steering an authenticated linked user's bot run with installation-level repository credentials and Kilo org context.
+- **Recommended fix:** Treat all GitHub-originated content as untrusted, including titles, bodies, comments, review comments, diff hunks, and filenames. Put untrusted GitHub context outside the system prompt when possible, and add a tool-call guard requiring repository/mode/task to be attributable to the triggering linked user's message or explicitly confirmed by that user. Add regression tests for malicious issue bodies, old comments, and diff hunks.
+
+### High: GitHub invocation lacks repository-permission checks for the linked GitHub user
+
+- **Affected files/functions:** `apps/web/src/lib/bot.ts` (`handleIncomingMessage`), `apps/web/src/lib/bot/platform-helpers.ts` (`getPlatformIdentity`, `getPlatformIntegration`), `apps/web/src/app/github/link/route.ts`, `apps/web/src/app/api/integrations/github/callback/route.ts`, `apps/web/src/lib/bot/tools/spawn-cloud-agent-session.ts`
+- **Issue:** The linking flow verifies Kilo org/user ownership, but invocation only checks that the GitHub sender ID is linked to a Kilo user. It does not verify the sender's GitHub repository permission, collaborator status, org membership, or `author_association`.
+- **Attack scenario:** A Kilo org member links a personal GitHub account with limited repo access. They comment where they are allowed to comment, but the bot uses broader Kilo GitHub installation privileges and can potentially spawn a Cloud Agent for repos the GitHub account cannot access.
+- **Impact:** GitHub permission boundaries are not enforced. A commenter with a linked Kilo account may act using installation-level privileges instead of their actual GitHub permissions.
+- **Recommended fix:** Before processing a GitHub mention, verify the sender's permission on the current repository using the installation token. Require appropriate permission by action type, re-check Kilo org membership at invocation time, and reject public-repo invocations that can act on private organization repos unless explicitly configured.
+
+### High: Private repository inventory can be exposed in public GitHub replies
+
+- **Affected files/functions:** `apps/web/src/lib/bot/agent-runner.ts` (`buildSystemPrompt`, `postSessionLinkEphemeral`), `apps/web/src/lib/slack-bot/github-repository-context.ts` (`formatGitHubRepositoriesForPrompt`), `apps/web/src/lib/bot/run.ts`, `apps/web/src/lib/bot/tools/spawn-cloud-agent-session.ts`
+- **Issue:** The system prompt includes available repositories for the integration, including private repository names marked `(private)`. GitHub bot responses are posted back into GitHub threads, which may be public.
+- **Attack scenario:** A linked user in a public repo asks what repos the bot can access, or prompt injection in issue/PR content instructs the model to list private repos. The model can reveal repository names from the prompt into a public GitHub comment.
+- **Impact:** Private repository names and metadata can leak to public GitHub users. Repo names alone can expose confidential projects, customers, acquisitions, vulnerabilities, or internal architecture.
+- **Recommended fix:** For GitHub invocations, scope repository context to the current repository unless the destination is known private and the sender is authorized. Do not include installation-wide private repo inventory in prompts that can produce public comments. Verify `@chat-adapter/github` behavior for `postEphemeral`; if it posts normal comments or cannot guarantee privacy, do not post sensitive session links through it.
+
+### High: Suspended GitHub integrations can still reach the bot path
+
+- **Affected files/functions:** `apps/web/src/app/api/webhooks/github/route.ts`, `apps/web/src/lib/integrations/platforms/github/webhook-handler.ts`, `apps/web/src/lib/bot.ts`, `apps/web/src/lib/bot/platform-helpers.ts` (`getPlatformIntegration`)
+- **Issue:** The webhook route schedules `bot.webhooks.github(...)` independently of the legacy `handleGitHubWebhook` result. The legacy path checks whether an integration is suspended, but the bot path only looks up by installation ID and does not filter `suspended_at`.
+- **Attack scenario:** A suspended integration receives a GitHub mention. The legacy path may skip, while the chat adapter still emits `onNewMention` and `handleIncomingMessage` processes it.
+- **Impact:** Suspension may not stop GitHub bot runs or Cloud Agent sessions.
+- **Recommended fix:** Gate the bot adapter path on the same active-integration and suspension checks as the legacy handler. Make `getPlatformIntegration` return only active integrations or explicitly reject suspended integrations in `handleIncomingMessage`.
+
+### Medium: GitHub webhooks can trigger duplicate privileged actions through legacy and bot paths
+
+- **Affected files/functions:** `apps/web/src/app/api/webhooks/github/route.ts`, `apps/web/src/lib/integrations/platforms/github/webhook-handler.ts`, `apps/web/src/lib/integrations/platforms/github/webhook-handlers/installation-handler.ts`, `apps/web/src/lib/bot.ts`
+- **Issue:** Every GitHub webhook goes to both the existing GitHub integration handler and the new chat adapter. `pull_request_review_comment` events may trigger legacy auto-fix and the new mention handler. The legacy path has webhook dedupe; the new bot path does not appear to share that idempotency.
+- **Attack scenario:** A review comment mentioning Kilo triggers both flows, or a GitHub retry repeats the bot path.
+- **Impact:** Duplicate agent sessions can cause repeated writes, comments, billing, and amplified prompt-injection impact.
+- **Recommended fix:** Decide a single owner for each event. Share webhook delivery dedupe keyed by `x-github-delivery`, filter the bot adapter to needed event types/actions, or migrate legacy auto-fix behind the new adapter.
+
+### Medium: Public GitHub account-link token is not bound to the GitHub commenter or repository
+
+- **Affected files/functions:** `apps/web/src/lib/bot/link-account.tsx`, `apps/web/src/lib/bot/github-link-token.ts`, `apps/web/src/app/github/link/route.ts`, `apps/web/src/app/api/integrations/github/callback/route.ts`
+- **Issue:** The public link token binds only `platformIntegrationId` and `installationId`. It does not bind the original GitHub sender, repo, issue/PR, intended Kilo user, or intended GitHub login/id.
+- **Attack scenario:** An unlinked user mentions the bot in a public issue. A different Kilo org member sees the public link and links their own GitHub account to that installation within the TTL.
+- **Impact:** This likely does not let a completely unauthenticated external user run the bot, but it weakens identity binding and combines dangerously with missing repo-permission checks.
+- **Recommended fix:** Include the original GitHub sender ID, repository, and issue/PR coordinates in the signed token and OAuth state. Require the OAuth-authenticated GitHub user ID to match the original sender. Prefer one-time server-side nonces for public GitHub comments.
+
+### Medium: Linked GitHub users are not revalidated against Kilo organization membership at invocation time
+
+- **Affected files/functions:** `apps/web/src/app/github/link/route.ts`, `apps/web/src/app/api/integrations/github/callback/route.ts`, `apps/web/src/lib/bot.ts`, `apps/web/src/lib/bot-identity.ts`
+- **Issue:** Kilo org membership is checked during linking, then a persisted Redis mapping from GitHub user ID to Kilo user ID is trusted later. `handleIncomingMessage` only checks that the Kilo user exists.
+- **Attack scenario:** A user links while they are an org member, is later removed, but keeps invoking the GitHub bot through the stale link.
+- **Impact:** Former org members may retain bot access to organization GitHub integrations.
+- **Recommended fix:** Re-check Kilo organization membership at every invocation. If no longer valid, delete the bot identity mapping and deny access or require relinking.
+
+### Medium: GitHub context fetch trusts adapter thread coordinates without checking selected repos
+
+- **Affected files/functions:** `apps/web/src/lib/bot/conversation-context.ts` (`parseGitHubThreadId`, `getGitHubConversationContext`)
+- **Issue:** The bot parses owner/repo/issue coordinates from `thread.id` and uses the installation token to fetch context, but does not verify that the repository is selected/allowed for the resolved integration.
+- **Attack scenario:** A malformed adapter event or unexpected thread ID points at a different repo accessible to the installation token. The bot fetches private issue/PR content and injects it into prompt context.
+- **Impact:** Repository-to-repository context leakage inside an installation, and larger blast radius if combined with wrong integration lookup.
+- **Recommended fix:** Verify parsed `owner/repo` against the integration's selected repositories before fetching context. Prefer immutable webhook metadata over parsing security-relevant coordinates from thread IDs.
+
+## Human Verification Items
+
+- Verify `@chat-adapter/github` independently validates `x-hub-signature-256` before emitting events.
+- Verify exactly which GitHub events become `onNewMention` events, especially issue bodies, edited comments, PR descriptions, review comments, and non-comment events.
+- Verify `Thread.postEphemeral` behavior for GitHub. If it posts public comments or exposes session URLs, treat session links as public.
+- Verify whether Cloud Agent session URLs require authorization and whether URL possession reveals metadata.
+
+## Positive Notes
+
+- The GitHub callback requires signed OAuth `state` and checks the authenticated Kilo user matches the state user ID.
+- The callback exchanges a GitHub OAuth code and links the returned GitHub user ID rather than trusting a query parameter.
+- `/api/chat/link-account` rejects GitHub identities, avoiding reuse of Slack's serialized-message link flow.
+- GitHub link token and OAuth state are HMAC-signed and short-lived.

+# Tests Review
+
+## Overall Assessment
+
+The PR adds substantial coverage for the GitHub bot adapter flow. Route-level tests cover many auth, access-control, and redirect cases, and conversation-context tests are likely to catch regressions in formatting and pagination.
+
+The main gaps are security-critical token/state helpers, installation deletion cleanup, non-GitHub regressions after the context refactor, and end-to-end linking compatibility. Several tests are heavily mocked at module boundaries, which makes them useful for routing assertions but less effective at catching integration regressions.
+
+## Findings
+
+### High: Security token helpers have no direct tests
+
+- **Affected files:** `apps/web/src/lib/bot/github-link-token.ts`, `apps/web/src/lib/bot/github-link-state.ts`, `apps/web/src/app/github/link/route.test.ts`, `apps/web/src/app/api/integrations/github/callback/route.test.ts`
+- **Issue:** The signed GitHub link token and OAuth state helpers are security-critical, but route tests mock `verifyGitHubLinkToken`, `createGitHubBotLinkState`, and `verifyGitHubBotLinkState` instead of exercising the real HMAC, TTL, payload validation, and tamper detection.
+- **Why it matters:** Regressions in signature generation, expiry handling, malformed payload rejection, missing-field validation, or future-dated token rejection would not be caught.
+- **Recommended improvement:** Add direct unit tests for both helper files covering round-trip creation/verification, tampered payload, tampered signature, missing fields, expired tokens, future `iat`, malformed base64/JSON, empty IDs, and unsafe callback paths. Use fake timers for TTL behavior.
+
+### High: Installation deletion identity cleanup is untested
+
+- **Affected files:** `apps/web/src/lib/integrations/platforms/github/webhook-handlers/installation-handler.ts`, `apps/web/src/lib/integrations/platforms/github/webhook-handler.test.ts`
+- **Issue:** The PR adds a side effect on GitHub installation deletion: initialize the bot and call `unlinkTeamKiloUsers`. The new webhook tests mock `handleInstallationDeleted`, so they cannot verify this behavior.
+- **Why it matters:** If uninstall no longer removes linked GitHub identities, users could remain linked to an installation that no longer exists.
+- **Recommended improvement:** Add focused tests for `handleInstallationDeleted` using the real handler with mocked DB, `bot.initialize`, `bot.getState`, `unlinkTeamKiloUsers`, and Sentry. Assert correct platform and installation ID, and assert unlink failures are captured without preventing existing deletion flow.
+
+### Medium: Conversation-context refactor lacks non-GitHub regression coverage
+
+- **Affected files:** `apps/web/src/lib/bot/conversation-context.test.ts`, `apps/web/src/lib/bot/conversation-context.ts`
+- **Issue:** New tests cover GitHub context, but the refactor also replaced the old platform-agnostic context path with `getPlatformContext`. There are no tests for Slack or generic adapters in the new suite.
+- **Why it matters:** Existing Slack behavior could regress without detection, including channel metadata, message ordering, trigger-message filtering, delimiter sanitization, DM/channel labeling, and fetch-failure behavior.
+- **Recommended improvement:** Add Slack and generic-adapter tests using fake `Thread`/`Channel` objects. Assert expected metadata, trigger exclusion, chronological ordering, sanitization, and empty-string fallback.
+
+### Medium: Webhook route tests codify broad bot dispatch but do not test failure isolation
+
+- **Affected files:** `apps/web/src/app/api/webhooks/github/route.test.ts`
+- **Issue:** Tests assert that installation and unrelated events are sent to the bot adapter, but they do not verify that adapter failures, thrown errors, or non-OK responses are isolated from the legacy webhook response.
+- **Why it matters:** The route intentionally runs the bot adapter in `after()`. A regression that lets bot failures affect GitHub webhook acknowledgements could cause retries or interfere with existing integration handlers.
+- **Recommended improvement:** Add tests where `bot.webhooks.github` rejects and where it returns a non-OK response. Assert `POST` still returns the legacy handler response and Sentry/logging is called.
+
+### Medium: Route tests are heavily mocked and miss end-to-end link-flow validation
+
+- **Affected files:** `apps/web/src/app/github/link/route.test.ts`, `apps/web/src/app/api/integrations/github/callback/route.test.ts`, `apps/web/src/lib/bot/link-account.test.ts`
+- **Issue:** The GitHub account-link flow is tested through isolated route mocks, but there is no test that stitches together real token creation, `/github/link`, OAuth state creation, callback verification, and `linkKiloUser`.
+- **Why it matters:** Tests can pass even if the token payload shape, OAuth state payload shape, or installation handoff between routes is incompatible.
+- **Recommended improvement:** Add an integration-style happy-path test using real `createGitHubLinkToken` and `createGitHubBotLinkState`, mocking only external dependencies such as auth, DB lookup, GitHub OAuth exchange, and chat state.
+
+### Medium: Callback access-control tests miss user-owned integration cases
+
+- **Affected file:** `apps/web/src/app/api/integrations/github/callback/route.test.ts`
+- **Issue:** Callback tests cover organization-owned integration success and membership rejection, but not user-owned integration success or rejection.
+- **Why it matters:** The callback route has separate logic for `owned_by_user_id`. A regression could link a GitHub user to the wrong Kilo user or reject legitimate user-owned installs.
+- **Recommended improvement:** Add tests where `owned_by_user_id === user.id` succeeds and `owned_by_user_id !== user.id` returns 403 without calling OAuth exchange or `linkKiloUser`.
+
+### Low: GitHub webhook handler test name is misleading
+
+- **Affected file:** `apps/web/src/lib/integrations/platforms/github/webhook-handler.test.ts`
+- **Issue:** A test name says non-created `issue_comment` events are acknowledged without invoking the bot, but `handleGitHubWebhook` does not invoke the bot adapter; bot dispatch happens in the route layer.
+- **Why it matters:** The name suggests coverage this file cannot provide.
+- **Recommended improvement:** Rename the test to say it does not invoke legacy handlers, or add route-level coverage for bot adapter dispatch.
+
+### Low: Documentation URL test locks in a placeholder for GitHub
+
+- **Affected file:** `apps/web/src/lib/bot/platform-helpers.test.ts`
+- **Issue:** The GitHub documentation URL expectation is the Slack URL.
+- **Why it matters:** This may be intentional while GitHub docs are unavailable, but the test now codifies the placeholder.
+- **Recommended improvement:** If intentional, make the test name/copy explicit. Otherwise, update implementation and test to expect a GitHub-specific docs URL.
