Forensic audit of an implementation against its authoritative specification. Use whenever a specification document and an implementation are both in scope and the user asks any conformance question - even when not phrased explicitly: 'does this code match the spec', 'verify this implementation', 'check spec…
Convert a technical specification, tracker reference, or feature request into a rigorous, atomic, dependency-ordered implementation plan the coder agent executes step-by-step. Use whenever the output is a Markdown plan file under .plans/, or when asked to plan, break down work, sequence implementation phases, turn a…
Write technical specifications from feature requests, prompts, or tracker references. Use when asked to specify, architect, design, write a spec, define requirements, create a technical specification, analyze a feature request, or produce a specification document. Also use when given a tracker reference (Jira, GitHub…
Validate a Dependabot configuration against the published JSON Schema and audit its groups against the repository's real dependency manifests. Use when creating or rewriting .github/dependabot.yml, when adding or reorganising groups, ignore or exclude-patterns, when a dependency lands in the wrong grouped PR or keeps…
Run a third-party CLI as a subprocess without leaking into it or leaving state on the host, and prove both. Use when a script or skill shells out to an external tool, when a run must leave no trace outside the repository, when private input (a diff, a prompt, a credential) must not reach the tool's session log, when a…
Drive a long-running GitHub Actions run to a trustworthy conclusion without burning the session on polling. Use when asked to wait for a pipeline, watch a build, babysit a release or deploy run, restart it if it fails, or report whether it went green. Also use when a run must finish before a follow-up step such as a…
Prove a passing check was capable of failing before recording it as evidence. Use when a test, CI job, build-and-diff, smoke test or rehearsal comes back green and that green is about to be treated as proof - especially when the check depends on a setup mutation (a sed/awk rewrite, an env var, a secret, a fixture…
Measure a candidate library's real maintenance state and its behavior against the protocol, schema, or API version the project has already pinned, before taking it as a dependency. Covers any ecosystem (Go, npm, PyPI, Cargo, Maven) and any forge (GitHub, GitLab, Gitea). Use when deciding whether to adopt, replace, or…
Brief a background agent, confirm the brief arrived, and verify its report before acting on it. Use when writing the prompt for a subagent or parallel session, when several agents will run against one repository, when an instruction sent to a running agent goes unmentioned in its report, when a delegated fix has been…
