msewell Bundle Reviewing Pull RequestsReviews GitHub pull requests end-to-end using gh CLI. Gathers PR metadata, diff, linked issues, and CI status. Analyzes code for bugs, security risks, performance issues, and goal alignment against repo conventions. Runs available lint, type-check, and test commands locally. Produces a prioritized report with severity-classified feedback (blocking, suggestion, nit, praise) and an approve/request-changes verdict. Optionally posts the review to GitHub after user confirmation. Use when asked to review a PR, check a pull request, audit code changes, evaluate if a PR is ready to merge, provide code review feedback, assess PR quality, or when the user says review PR #N, is this PR ready, look at this pull request, or code review.

netalertx Skill Plugin ReadmeWrite or review a NetAlertX plugin's README.md (server/plugins/<code_name>/README.md). Use this when asked to create, enhance, audit, or clean up a plugin README, or plugin docs generally.
-
netalertx Skill Skill HygieneRead before writing or editing any SKILL.md, or any research/audit doc in .gemini/internal-docs/research/. Covers the two standing rules for living-reference prose - state current behavior only, and prefer plain, short wording - plus the grep sweep to run before calling a doc clean. PRDs are the deliberate exception (they keep a correction trail).

g-bastianelli Skill Audit SpecReview an existing spec for contradictory behavior, unverifiable acceptance, unsupported decisions, and repository conflicts. Returns concrete blockers and a readiness verdict; use before ratification or when a spec's quality is in doubt.
-
g-bastianelli Skill Write SpecTurn a feature or project request into a codebase-grounded spec with observable acceptance criteria and an independent audit. Use when a written spec is wanted before planning or Linear issue breakdown.
-
g-bastianelli Skill Write ConstitutionUse when a project needs immutable governing principles that every spec / audit / drift check is held against — runs a one-question-at-a-time interview to extract project-specific articles (test-first, anti-abstraction, library boundaries, etc.), writes them to docs/acid-prophet/constitution.md, and commits. The spec-auditor reads this file on every audit and treats each article as an extra gate.
