From 02639474ce069f779d7a598a7311d28ad0798584 Mon Sep 17 00:00:00 2001 From: "Ashrya Agrawal (from Dev Box)" Date: Fri, 10 Apr 2026 16:22:56 -0700 Subject: [PATCH 01/29] Add `a365 evaluate` command for MCP tool schema quality evaluation 5-step pipeline: discover tools from MCP server, generate auditable checklist, evaluate semantic checks via coding agent CLI (GitHub Copilot or Claude Code), analyze scores/maturity/action items, render HTML report. Key design decisions: - Extract-evaluate-merge pattern: each tool evaluated in its own ~25KB temp file to avoid coding agent timeouts on large checklists - Engine fallthrough: tries Copilot first, then Claude Code, with per-tool 6-minute timeout and process tree cleanup on timeout - Copilot uses prompt-file approach (no stdin support); Claude uses stdin piping - 25 deterministic checks (C#) + 12 semantic checks per tool (coding agent) - 18-smell taxonomy with weighted 5-category scoring and maturity levels 0-4 - 318 new tests (xUnit + FluentAssertions) --- .../Commands/EvaluateCommand.cs |

Adds a DevelopMcpCommand.CreateCommand overload that accepts the pipeline service; the existing 2-param signature remains for tests that don't need evaluate.

Rework the output around a 5-step pipeline with aligned indented detail lines. Key changes: - Step markers [1/5]..[5/5] for discovery, checklist, eval, analysis, report. - Single "Using " line (with optional fallback) instead of three "Detecting / Available / Engines available" lines. - Per-tool progress prints once per tool with an inline status ("ok" or "failed (continuing)"), not before+after. - Demote "Coding agent completed / exited / timed out" to debug — the user already sees success/failure on the per-tool line. - When no coding agent CLI is found, write the semantic eval prompt to semantic_eval_prompt.txt next to the checklist and guide users through install options OR scoring with their own LLM. - Remove the old "Analyzing results..." / "Analysis complete" / "Generating report..." intermediate lines; the step markers and trailing "Done. Score" line already convey that information. - Suppress the extraneous initial checklist-path log at Information level.

Previously a single successful tool would flip the flag to true, letting Scorer treat still-null categories as perfect 100 and inflate overall scores on partial runs. - Switch `develop-mcp evaluate`'s required input from a positional `server-url` argument to a required `--server-url` / `-u` option, for consistency with the other develop-mcp subcommands and the Azure CLI compliance regression test. - Route `ToolsetDesign` checks to `Scorer.ToolsetWeight` in ActionItemGenerator so action-item score impact stays aligned with overall scoring; removes an implicit reliance on the 0.15 fallback coincidentally matching ToolsetWeight. - Add ArgumentNullException guards to the EvaluationPipelineService constructor for parity with the rest of the codebase's DI services. - Expose ChecklistEvaluator.RepairJson as internal and add unit tests covering well-formed input, missing commas between objects/strings/ booleans, and empty input. - Relax DevelopMcpCommandTests subcommand-count assertions to check for presence/absence of "evaluate" instead of asserting a hardcoded total, so unrelated subcommand additions don't break these tests. - Add `because:` clauses to DeriveServerName assertions so the intent of each URL-sanitization invariant is documented at the assertion site.

If present, it loads that file as the source of truth and skips discovery/generation — the user's scores survive. - Drop the `engine != EvalEngine.None` carve-out. Any incomplete evaluation (no agent, partial scores, explicit opt-out) now stops with actionable guidance regardless of engine. - ChecklistEvaluator no longer blindly overwrites the file at the top of EvaluateAsync. A new WriteChecklistAsync writes only when it's safe, and the fully-scored shortcut skips agent invocation entirely. - LogManualEvaluationInstructions now differentiates the engine-not-found vs partial-opt-out cases, and the pipeline appends the concrete re-run command with the user's actual --server-url and --output-dir (no more values). Verified end-to-end for all four paths (GitHub Copilot, Claude Code, --eval-engine none, and auto with no agents on PATH), and confirmed that re-running the same command after scoring a checklist generates the final report without touching the MCP server.

For a product release, "issue" is the neutral, user-facing term that matches how developers already think about things they need to fix, and it keeps the report framing clear without external vocabulary choices. - Rename types: SmellDefinition -> IssueDefinition, SmellTaxonomy -> IssueTaxonomy, SmellCategory -> IssueCategory, SmellImpactInfo -> IssueImpactInfo. Files renamed to match. - Rename properties / JSON fields: smell_ids -> issue_ids, smell_summary -> issue_summary, smells_detected -> issues_detected. - Update the semantic-eval prompt so coding agents see the new JSON field name in the "do not modify" list. - Update HTML template footer and comments to drop external attribution. - Update all tests and XML doc comments to the new terminology.

Diagnosed by reproducing the exact Copilot invocation in a scratch directory and reading ~/.copilot/logs — the str_replace_editor also requires old_str to be unique in the file, which the repeating "score": null pattern breaks. Fixes: - Invoke Copilot with --allow-all-tools so non-interactive pre-approves tool use, but cap what tools the model sees via --available-tools=view,edit,create. powershell, web, shell etc. are hidden from the model entirely. create is added so the agent can rewrite the whole file when individual edits fail. - When an agent is detected and invoked but leaves checks unscored, fall back to the same manual-scoring guidance we print when no agent is installed — instead of silently warning and returning. Adds agentAttempted: bool to LogManualEvaluationInstructions so the message names what actually happened. E2E on learn.microsoft.com with --eval-engine github-copilot now scores 34/48 (was 0/48) and the 14 remaining checks surface the BYOL prompt file.

Those edits failed on the repeating "score: null" pattern that isn't unique across checks, and the subprocess still exited 0 so the pipeline logged "ok" with nothing merged. Fix: build a per-engine prompt that names the exact tool the agent should use. SemanticCheckPrompts now takes an AgentToolset record describing ReadToolName/WriteToolName/EditToolName, and ChecklistEvaluator maps EvalEngine to the concrete names (Copilot: view/create/edit, Claude Code: Read/Write/Edit). The prompt instructs "use Write/create ONCE" and warns away from targeted string replacements. Also add Write to Claude Code's --allowedTools since a whole-file write is the reliable strategy for both engines. E2E on learn.microsoft.com: 46/48 scored consistently (was 20-34 flaky); the 2 remaining are the toolset-level server checks, which we'll follow up on separately.

Inverting the restriction (allow everything, deny the dangerous families) lets the agent use its full toolkit for the scoring task while blocking the two ways it could escape the sandbox or leak data. Denies: Copilot: shell, write_shell, read_shell, stop_shell, list_shell (macOS/Linux), powershell, write_powershell, read_powershell, stop_powershell, list_powershell (Windows), web_fetch, web_search Claude Code: Bash, BashOutput, KillBash, WebFetch, WebSearch File access remains bounded by the per-invocation temp-dir sandbox — file tools respect cwd by default, and we don't pass --allow-all-paths. Prompt simplified: we no longer over-instruct the agent on which tool to use, just name the read/write tool names it has and describe the write-in-one-call strategy as a preference, not a restriction.

Before this change, the pipeline accepted whatever came back from the first agent call, so runs would flake between 30/48 and 48/48 scored on identical inputs — the same tool or same pair of server-level checks would score one run and skip the next. Change: EvaluateToolChecks and EvaluateServerChecks now loop up to MaxAttempts (3) times. After each agent pass we merge scored items back into the in-memory checklist, re-serialize the current state to the temp file (so the next attempt only sees the items that are still null), and stop early as soon as everything is scored. Also wrap the deserialize-and-merge step in try/catch (JsonException). When the agent writes structurally invalid JSON (e.g. an abbreviated ChecklistItem object), we now log and retry instead of crashing the whole pipeline with an unhandled exception. E2E on learn.microsoft.com: 48/48 scored in a single run, score 90/100, full report generated (previously needed a resume run to finish the last 2 server-level checks).

If the first attempt hit the per-tool timeout, we gave up immediately ("retry would just repeat the same subprocess failure"). That assumption was wrong: on Haiku + Copilot we see non-deterministic timeouts — the same tool that times out on attempt 1 often completes on attempt 2 or 3 because Copilot's runtime is warmer, or the model happens to pick a shorter reasoning path. On the Mail MCP eval, 6 tools (SendEmailWithAttachments, GetMessage, FlagEmail, UploadAttachment, UploadLargeAttachment, ForwardMessage) ended with 0/N scored — all single-attempt timeouts that never got a retry. Similar-sized tools next to them in the pipeline completed fine on first attempt. Change: on subprocess failure, log and continue the retry loop instead of returning false. Still return false if *all* MaxAttempts subprocess calls fail — we're not pretending an unreachable agent succeeded. Same fix applied to EvaluateServerChecks.

charset=UTF-8 Content-Transfer-Encoding: 8bit Root cause of the Mail-MCP 0/N failures on GetMessage, FlagEmail, and UploadAttachment: Copilot's `create` tool cannot overwrite existing files ("Cannot be used if the specified path already exists"). We were telling the agent to "rewrite the whole file via create" — a strategy that physically fails the moment the pre-populated temp file exists. Some tools happened to stumble onto workarounds (create siblings, copy fields back); others (usually smaller ones like GetMessage, 54-char description) kept looping on the create->edit->view fallback dance for 9 minutes straight until timeout. Fix: use an edit-only (string-replace) flow. - SemanticCheckPrompts: - AgentToolset now names a read tool and an edit tool (no write tool). - New prompt instructs the agent to call edit once per null item with an old_str that includes both the item's id and its prompt field, which is globally unique in the file. - Explicit "answer with first instinct, do not re-read after a successful edit" rule to discourage the checking loop. - ChecklistEvaluator.ToolsetFor: Copilot=(view, edit); Claude=(Read, Edit). - CodingAgentRunner: - Copilot: --available-tools=view,edit (drops `create`). - Claude: --allowedTools Read,Edit (drops Write). Validated on learn.microsoft.com and the Mail MCP server: - learn.microsoft.com: 48/48 scored, 92/100, ~6.5 min total (was 46/48). - Mail MCP resume: 6 previously-failing tools all score first-attempt in ~2 min each (was 28 min + failing).

Each layer covers a specific failure the others miss: - L1 PromptSanitizer (new): strips bidi overrides, zero-width chars, C0/C1 controls, and U+E0000-U+E01EF tag-block from tool names, descriptions, and param names before they reach the agent. Without this, hidden Unicode in MCP content survives spotlighting and L3 keyword filters. - L2 spotlighting: prepends a SECURITY BOUNDARY header and wraps tool names in tags in all 3 prompt builders. Without this, the agent has no signal that schema content is untrusted. - L3 ScoringSafetyFilter (new): rejects agent reasons containing exfil URLs (http/https/ftp/data:) or prompt-injection markers ("ignore previous instructions", "system:", etc.). Cleared items go through the existing retry loop. Without this, exfil links and reproduced injection text reach the report. - L4 canary: injects a fake check whose correct answer is always false (random UUID match). A true score signals plan drift, logged as SECURITY error and surfaced via PlanDriftDetected on the result. This is the only post-hoc detector if L1-L3 fail silently. Also adds F-002 XSS defense-in-depth: routes maturity.label and AREA_LABELS values through esc() in SchemaEvalReport.html. Combined with the existing System.Text.Json encoding and EscapeForInlineScript layers, all 24 MCP-controlled fields are now escaped before any innerHTML assignment. Tests: PromptSanitizerTests, ScoringSafetyFilterTests, plus XSS regression tests in ReportGeneratorTests. All 148 affected tests pass.
