+
+# Dev Loop
+
+Complete a development task end-to-end: implement, build, test, push, create PR, monitor CI, fix failures.
+Do NOT stop until CI is green or you are blocked.
+
+## Phase 1: Implement
+
+1. Read and understand the task from $ARGUMENTS
+2. Explore relevant code
+3. Implement the changes
+4. Build: `cmake -S . -B cmake-build -DCMAKE_BUILD_TYPE=Release -DCOLLECTOR_VERSION=$(git describe --tags --abbrev=10 --long) && cmake --build cmake-build -- -j$(nproc)`
+   - If build fails, fix and retry
+5. Test: `ctest --no-tests=error -V --test-dir cmake-build`
+   - If tests fail, fix and retry
+6. Format: `clang-format --style=file -i <changed .cpp/.h files>`
+7. Commit: `git add` changed files, `git commit` with a descriptive message
+
+## Phase 2: Push and create PR
+
+Use the GitHub MCP server to push files and create a PR.
+Do NOT use `git push` — it will fail (no SSH keys in this container).
+
+1. Get the current branch name and the list of changed files:
+   - `git branch --show-current` for the branch
+   - `git diff --name-only origin/HEAD..HEAD` for changed files
+2. Use the GitHub MCP `push_files` tool to push the changed files directly to
+   the remote branch. This creates a commit via the GitHub API using the file
+   contents from your local workspace — it does not sync git history.
+   - owner: stackrox, repo: collector, branch: <current branch>
+   - Read each changed file and include its content
+   - Provide a commit message
+3. Search for an open PR for this branch via GitHub MCP
+4. If no PR exists, create a draft PR via GitHub MCP
+
+## Phase 3: Monitor CI
+
+Loop until all checks pass or blocked (max 6 cycles, ~3 hours):
+
+1. Wait 10 minutes: `sleep 600`
+2. Check CI status via GitHub MCP (PR checks, workflow runs)
+3. Update PR body with an `## Agent Status` section:
+   ```
+   ## Agent Status
+   **Last updated:** <`date -u +"%Y-%m-%d %H:%M UTC"`>
+   **CI cycle:** N of 6
+   **Status:** PENDING | PASSED | FIXED | FLAKE | BLOCKED
+   **Details:** <one-line summary>
+   ```
+4. Evaluate:
+   - **All checks passed** → update PR body, report success, stop
+   - **Still running** → continue loop
+   - **Failed** →
+     - Get job logs via GitHub MCP
+     - Diagnose: build error, test assertion, lint, infra flake
+     - If fixable: fix → build → test → push changed files via MCP → continue
+     - If infra flake: note as FLAKE, continue
+     - If not fixable: update PR body, report BLOCKED, stop
+
+## Phase 4: Check PR comments
+
+Before each CI cycle, check if there are new PR review comments via GitHub MCP.
+If a reviewer left feedback:
+- Address the feedback (edit code, fix issues)
+- Build and test
+- Push changed files via MCP
+- Note in the Agent Status section what feedback was addressed
+
+## Completion
+
+Print summary:
+```
+STATUS: PASSED | BLOCKED | TIMEOUT
+Branch: <branch>
+PR: <url>
+Cycles: N
+Changes: <list of files modified>
+```

+# Watch CI
+
+Push changed files via the GitHub MCP server, create PR if needed, and monitor CI until green.
+Do NOT use `git push` — it will fail (no SSH keys in this container).
+
+## How pushing works
+
+Use the GitHub MCP `push_files` tool to send file contents directly to the remote
+branch via the GitHub API. This does NOT sync local git history — it creates a new
+commit on the remote with the file contents you provide.
+
+1. Get the branch name: `git branch --show-current`
+2. Get changed files: `git diff --name-only origin/HEAD..HEAD`
+3. Read each changed file's content
+4. Call `push_files` with owner: stackrox, repo: collector, branch, files, and commit message
+
+## Steps
+
+1. **Push** changed files:
+   - Use the GitHub MCP `push_files` tool as described above
+   - If no files have changed since last push, skip
+
+2. **Find or create PR**:
+   - Use the GitHub MCP server to search for an open PR for this branch
+   - If no PR exists, create a draft PR via the GitHub MCP server
+
+3. **Monitor CI loop** (repeat until all checks pass or blocked):
+   - Wait 10 minutes: `sleep 600`
+   - Use the GitHub MCP server to get PR check status and workflow runs
+   - Update PR body with an `## Agent Status` section:
+     ```
+     ## Agent Status
+     **Last updated:** <`date -u +"%Y-%m-%d %H:%M UTC"`>
+     **CI cycle:** N of 6
+     **Status:** PENDING | PASSED | FIXED | FLAKE | BLOCKED
+     **Details:** <one-line summary>
+     ```
+   - Evaluate:
+     - **All checks passed** → update PR body, report success and stop
+     - **Checks still running** → report progress, continue loop
+     - **Checks failed** →
+       - Get job logs via the GitHub MCP server
+       - Diagnose:
+         - Build failure: read error, fix code
+         - Unit test failure: read assertion, fix code
+         - Lint failure: run `clang-format --style=file -i`
+         - Integration test infra flake (VM timeout, network): report as flake, continue
+         - Integration test real failure: analyze and fix code
+       - If fixable: fix → build → test → push changed files via MCP → continue loop
+       - If not fixable: update PR body, report diagnosis and stop
+
+4. **Safety limits**:
+   - Maximum 6 CI cycles (about 3 hours of monitoring)
+   - If exceeded, update PR body and stop
+
+5. **Summary**: end with a status line:
+   - `PASSED` — all checks green
+   - `PENDING` — checks still running
+   - `FIXED` — failure diagnosed and fix pushed
+   - `FLAKE` — infra failure, not a code issue
+   - `BLOCKED` — failure requires human intervention
