Cut and shepherd an ephpm release (tag, CI matrix, publish, verify). Use when the user wants to release a new version, an RC, or to rescue a stuck/partially-failed release run.
Diagnose a failing ephpm CI run (E2E, unit, deny, release). Use whenever a GitHub Actions check is red or queued-forever - it encodes the diagnostic ladder for crashes vs test failures vs runner/infra problems, and the self-hosted (ephemerd) runner fleet quirks.
Checklist for adding or changing an ephpm config field so it can never become a silent no-op. Use whenever a PR adds a key to ephpm-config, changes a default, or defers a knob's implementation.
Run a claims-vs-code truth audit of ephpm documentation (site/, docs/, examples/, README). Use before releases, after large refactors, or when the user asks whether the docs match reality. Finds documented features that don't exist, wrong defaults, and undersold shipped features.
Reproduce ephpm E2E test failures locally against a containerized release build (podman), without the Kind/Tilt cluster. Use when CI E2E is red and you need fast iteration, or to verify a server-side fix before pushing.
Repo-specific review lens for ephpm PRs - the FFI, threading, platform, and CI landmines a generic code review misses. Use when reviewing any PR touching ephpm-php, ephpm_wrapper.c, ephpm-server, config, workflows, or docs.
