Design agent tool sets with stable names, narrow schemas, deterministic output shapes, and explicit error paths. No catch-all tools unless unavoidable.

Use when optimizing agent runtime loops, card packs, MCP session lifecycle, tool-call count, or multi-agent orchestration patterns.

Use when diagnosing agent session history, interrupted tool loops, missing tool results, timing bottlenecks, or subagent trace correlation.

Verify that API endpoints match their OpenAPI/Swagger specifications.

Use to collapse over-engineered abstractions, remove unnecessary layers, or consolidate redundant logic.

Use when a Codex or generic local agent needs a focused second opinion from Gemini CLI without MCP routing.

Analyze BigQuery usage, identify cost hotspots, repeated failures, and practical optimization opportunities.

Fix the failing build, test, or type check. Nothing else.

Process-first advisor routing with artifact capture

Use before submitting a PR or considering a task done to evaluate the 'blast radius' of your changes.

Use when a CI pipeline fails to extract the actual error from thousands of lines of logs.

Gather documentation context before writing or updating docs. Prevents duplicating existing content or violating project conventions.

Audit the methodology used to split data into train, validation, and test sets.

Audit whether a dbt incremental model uses the right incremental strategy for the repo, the data shape, and the operational constraints.

Inspect changed dbt assets, estimate blast radius, identify missing tests, and recommend the narrowest safe validation plan.

Coordinate multi-system deployment steps as a review-first runbook with explicit approval before any external write or promotion action.

Audit documentation for broken file paths, outdated commands, and renamed variables.

Use when confronted with an unknown failure in CI or production to rapidly categorize the issue before deep debugging.

Use when designing or reviewing filesystem MCP access, path boundaries, allowed roots, method allowlists, and safe local file operations.

Use to diagnose tests that pass and fail intermittently without code changes.
