Guardrails

Verification gates that block the agent from proceeding until checks pass. The agent already knows what linting, testing, type checking, and security scanning are. This skill doesn't re-teach those concepts. Instead, it specifies:

• When each check runs in the agent lifecycle (hooks that block progress)
• What to do when stuck (diagnostic escalation instead of retrying)
• What not to touch (config protection, high-risk action gating)
• How to accumulate knowledge (lessons learned, agent tool library)

These are the behaviors a coding agent wouldn't exhibit without being told. Everything else — which linter to use, how to structure a unit test — the agent already knows from training and discovers from the project's existing config.

Bundled resources: references/tool-building.md contains the diagnostic tool and notation catalogs with worked examples. references/language-defaults.md is a lookup table for tool selection by ecosystem. Read these when directed, not proactively.
