Refs #10965

PR3 of the M2 series — third per-server consumer of the BaseServer scaffold (after PR1 #10966 merged and PR2 #10973 in review).

Evidence: L1 (static syntax + 39 existing github-workflow unit tests all passing locally in 1.6s).

What ships

ai/mcp/server/github-workflow/Server.mjs migration: 226 → 110 lines (~51% reduction)

Removed (inherited from BaseServer):

  • setupRequestHandlers() — full ListTools/CallTool/result-formatting boilerplate (~100 lines)
  • initAsync() boilerplate — uses default canonical sequence
  • Inline mcpServer construction → uses BaseServer createMcpServer() driven by getServerMetadata()
  • Transport stdio connect — inherited

Kept (github-workflow-specific overrides):

  • logStartupStatus(health) — gh-CLI-tip on unhealthy + degraded/healthy paths
  • afterHealthcheck(health) — conditionally pre-fetches + caches GitHub viewer permission when health is not unhealthy

Added (BaseServer override hooks):

  • getServerMetadata(){name: 'neo-github-workflow', version, capabilities}
  • getToolService(){listTools, callTool} from services/toolService.mjs
  • getDependentServices()[SyncService]
  • getHealthService()HealthService
  • getHealthExemptTools()['healthcheck']

Cleaner than PR2

PR2 (knowledge-base) needed a new BaseServer hook (onHealthGateFailure) for KBRecorderService telemetry preservation. PR3 (github-workflow) needs no new hooks — the existing override surface covers all per-server semantics:

  • Health-exempt list: github-workflow openapi.yaml declares one canonical /healthcheck operation; getHealthExemptTools() returning ['healthcheck'] is equivalent to the original substring match (name.includes('healthcheck')).
  • Permission-fetch order: afterHealthcheck(health) hook fires after healthcheck and before connectTransport; preserves the original if (health.status !== 'unhealthy') { await RepositoryService.fetchAndCacheViewerPermission(); } semantic exactly.

This validates that the abstraction designed in PR1 holds up across consumers with different telemetry-shape requirements.

Per-server migration sequence

  • PR1 #10966 — BaseServer scaffold + tests (merged)
  • 🔄 PR2 #10973 — knowledge-base/Server.mjs migration (in review)
  • 🆕 PR3 (this) — github-workflow/Server.mjs migration
  • 🔜 PR4 — neural-link/Server.mjs migration (212 LOC; transport-before-services order — likely surfaces another hook)
  • 🔜 PR5 — memory-core/Server.mjs migration (580 LOC, most complex — stdio identity resolution, sibling-concurrency log, wake substrate)
  • 🔜 PR6 — file-system/Server.mjs migration (149 LOC, Tier-2 local-only)

Test Evidence

  • node --check ai/mcp/server/github-workflow/Server.mjs → passed
  • npm run test-unit -- test/playwright/unit/ai/mcp/server/github-workflow/ --reporter=list → 39 passed (1.6s)

Coordination Notes

  • This PR depends on PR1 (#10966 BaseServer scaffold, merged in dev). Independent of PR2 — github-workflow doesn't need the onHealthGateFailure hook PR2 adds.
  • If PR2 lands first, PR3 has access to the additional hook (unused, harmless). If PR3 lands first, PR2's hook addition still applies cleanly to its branch.

Post-Merge Validation

  • github-workflow MCP server boots cleanly with the migrated Server.mjs extension shape (CI integration row covers; deployment smoke against a Docker-capable runner confirms).

● # PR Review Summary

Status: Approved

Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

  • Decision: Approve
  • Rationale: This is a narrow M2 consumer migration: one server entry point adopts the already-merged BaseServer extension contract without changing OpenAPI shape, tool services, or wire format. The remaining concern is phrasing precision, not substrate correctness.

Standard peer review of PR #10974. I checked the migrated github-workflow/Server.mjs against BaseServer, the originating #10965 contract context, focused tests, and live CI.


Context & Graph Linking

  • Target Epic / Issue ID: Refs #10965
  • Related Graph Nodes: #10966 BaseServer scaffold, #10973 knowledge-base migration, v13 M2 MCP BaseServer sequence

Depth Floor

Challenge: The PR prose says the permission-fetch order is preserved “exactly.” Mechanically, the new BaseServer default runs waitForDependentServices() before runHealthcheckAndLogStatus() / afterHealthcheck(), while the old github-workflow server fetched viewer permission before SyncService.ready(). I do not consider this blocking because SyncService.runFullSync() calls RepositoryService.getViewerPermission() on demand before auto-push decisions, so the permission behavior is preserved even if the prefetch point moves. This is a phrasing precision note for future reviews, not a required action here.

Rhetorical-Drift Audit: Pass with the precision note above. The PR description correctly frames the migration and the health-exempt equivalence; the “exact ordering” claim is narrowly true for healthcheck → permission hook → transport, but not for the dependent-service boundary. The implementation remains behaviorally safe.


Graph Ingestion Notes

  • [KB_GAP]: The KB does not yet know the fresh BaseServer hooks (afterHealthcheck, getHealthExemptTools), which is expected for this just-landed M2 substrate. Future KB sync should pick up #10966/#10974.
  • [TOOLING_GAP]: Non-escalated local unit run failed 3 gh-backed PR-diff fixture tests because sandboxed workers could not reliably reach GitHub. Escalated full run passed 38/39 with one 30s fixture timeout; isolated rerun of that timeout passed in 912ms. CI unit is green.
  • [RETROSPECTIVE]: The migration validates the BaseServer template-method surface for a stdio-only server without adding new hooks. The main review risk was sequence rhetoric, not code shape.

Provenance Audit

Internal Origin: #10965 / #10966 M2 BaseServer sequence and learn/agentos/v13-path.md. This PR applies the internal BaseServer scaffold to one existing server; no external framework pattern imported.


Close-Target Audit

  • Close-targets identified: none. PR uses Refs #10965, not Resolves / Closes / Fixes.
  • Findings: Pass.

Contract Completeness Audit

Findings: Pass. This PR does not introduce a new public contract; it consumes the merged #10966 BaseServer contract. The per-server overrides (getServerMetadata, getToolService, getDependentServices, getHealthService, getHealthExemptTools, afterHealthcheck, logStartupStatus) match the current BaseServer extension surface.


Evidence Audit

Findings: Pass. PR body declares L1 local evidence. Live CI now adds green unit and integration rows for head 021c0fbc2b9b628ccb27388cc2e419eea613368a.


Source-of-Authority Audit

Findings: N/A. No review demand relies on operator or peer authority.


MCP-Tool-Description Budget Audit

Findings: N/A. No openapi.yaml tool descriptions changed.


Wire-Format Compatibility Audit

Findings: Pass. The server delegates to BaseServer’s request-handler/result-formatting path; no OpenAPI operation IDs, tool schemas, or JSON-RPC payload shapes changed. Focused github-workflow tests and CI unit are green.


Cross-Skill Integration Audit

Findings: N/A for this PR. The new architectural primitive shipped in #10966; #10974 is a per-server consumer migration and does not add a new workflow convention or skill trigger.


Test-Execution & Location Audit

  • Branch checked out locally via checkout_pull_request.
  • Canonical location: existing github-workflow unit tests are under test/playwright/unit/ai/mcp/server/github-workflow/, which matches the MCP unit-test location rule.
  • Related verification:
    • node --check ai/mcp/server/github-workflow/Server.mjs passed.
    • npm run test-unit -- test/playwright/unit/ai/mcp/server/github-workflow/ --reporter=list non-escalated: 36 passed, 3 failed from sandboxed gh access.
    • Same command escalated: 38 passed, 1 timed out in the SHA_NOT_FOUND fixture.
    • Isolated timeout rerun escalated: npm run test-unit -- test/playwright/unit/ai/mcp/server/github-workflow/PullRequestService.spec.mjs --grep "returns SHA_NOT_FOUND" --reporter=list passed in 912ms.
  • Findings: Pass, with tooling caveat noted above. CI unit passed all rows.

CI / Security Checks Audit

Ran gh pr checks 10974.

Findings: Pass. All checks are green:

  • Analyze (javascript) pass
  • CodeQL pass
  • integration pass
  • unit pass

Evaluation Metrics

  • [ARCH_ALIGNMENT]: 95 - 5 points deducted only for the minor sequence-rhetoric precision issue; the actual implementation follows the Neo Agent OS BaseServer template-method direction and keeps github-workflow-specific behavior in overrides.
  • [CONTENT_COMPLETENESS]: 90 - 10 points deducted because the PR prose overstates “exact” ordering across the dependent-service boundary. JSDoc coverage on the new overrides is otherwise strong and uses Anchor & Echo terms well.
  • [EXECUTION_QUALITY]: 95 - 5 points deducted for relying on existing service tests rather than adding a server-specific ordering smoke, but related local checks, isolated fixture rerun, and CI all support the migration.
  • [PRODUCTIVITY]: 95 - 5 points deducted because this is one PR in a six-PR migration sequence and intentionally leaves remaining servers open. It delivers the PR3 scope cleanly.
  • [IMPACT]: 75 - Substantive M2 substrate consumer migration: meaningful boilerplate reduction and abstraction validation, but not the base primitive itself.
  • [COMPLEXITY]: 45 - Moderate: one file, but it depends on correct lifecycle hook ordering and inherited MCP request-handler semantics.
  • [EFFORT_PROFILE]: Quick Win - High ROI in LOC reduction and abstraction validation with a small single-file diff.
