Skills SDK for Codex/AI coding agents: author, validate, evaluate, and sync runtime projections through ask.
This repository also configures its own agents. See what Agent-Skills tells them →
Skill Codex
Creates release-ready skill packages from proven workflows by drafting SKILL.md frontmatter, trigger-rich instructions, references/contract.yaml, eval scenarios, task profile, and validation commands. Use when the user asks to create a skill, skillify a workflow, package a process, write SKILL.md, make a reusable…
Skill Codex
Reviews and improves SKILL.md packages by fixing audit findings, triggers, examples, evals, token budget, release proof, safety verdicts, comparator/baseline choices, and bounded code-lens hardening. Use when the user says improve a skill, fix a skill file, review SKILL.md, raise Tessl score, reduce context cost, add…
Skill Codex
Review Codex skill-management intent to select its downstream owner. Use when the owner is ambiguous or the user explicitly asks for routing, not when a downstream lane is already clear.
Skill Codex
Analyze options and trade-offs before traceable work is ready, without pretending exploration is a plan. Use when the user wants options, alternatives, decision matrices, or a bounded ideation pass before trace planning.
Skill Codex
Generate closure proof with exact commands, outcomes, artifact paths, untested lanes, and residual risk. Use when work and review need a receipt before closeout, release, tracker movement, or handoff.
Skill Codex
Plan how to implement one approved slice, including file targets, validation gates, rollback, and proof lanes. Use when a slice spec is accepted and the user needs the implementation order before code changes.
Skill Codex
Analyze stale or conflicting lifecycle state by separating local, PR, CI, review, tracker, artifact, and session truth. Use when status is confused, work resumed after drift, evidence lanes disagree, or a closeout claim may be stale.
Skill Codex
Plan a stuck, stale, or unsafe frame into a smaller viable direction with rollback and decision boundaries. Use when a migration, plan, PR, or implementation path is producing churn, conflicting claims, or unsafe scope.
Skill Codex
Create a durable guardrail, validator, doc, eval, or skill-reference update from a verified failure or learning. Use when the user asks to capture learning, prevent recurrence, encode review feedback, or refresh stale guidance.
Skill Codex
Review the completed slice for correctness, risk, evidence gaps, and next-stage blockers. Use when the user asks for review, PR readiness, risk assessment, blocker identification, or post-work verification.
Skill Codex
Create one selected trace or tracker slice spec with acceptance criteria, constraints, validation, and exit conditions. Use when exactly one slice has been selected and needs a buildable contract before implementation planning.
Skill Codex
Plan traceable work bullets that connect intent, evidence, acceptance, and proof gaps. Use when an idea or reframe needs decomposition into traceable work units before tracker or slice specification.
Skill Codex
Plan tracker-ready slices with dependencies, labels, acceptance fields, and validation placeholders. Use when trace work needs Linear-ready or tracker-ready issue structure without actually mutating the tracker.
Skill Codex
Build only the approved slice while preserving scope, unrelated worktree changes, and validation evidence. Use when an approved execution plan or explicit bounded task is ready for implementation.
Skill Claude Code
Canonical skills live in categorized folders below.
Skill Codex
Use when reviewing, creating, shrinking, or refactoring AGENTS.md and directly linked instruction guidance for stale or conflicting rules against current model documentation, scoped routing, deduplication, or progressive disclosure.
Skill Claude CodeCodex
Create or review an explicit pre-action alignment checkpoint. Use when the user requests a checkpoint or an unresolved decision materially changes scope, risk, or authority; ordinary bounded implementation does not require a checkpoint.
Skill Codex
Apply approved fixes for unresolved CodeRabbit review comments, Codex P1-P3 findings, PR feedback, and code review issues with validation evidence. Use when asked to address review comments, fix review findings, clear unresolved comments, or autofix PR feedback.
Skill Codex
Run bounded automated experiment iterations by recording baselines, applying hypothesis patches, comparing metrics, protecting regression guards, and deciding keep, discard, rollback, or block. Use when automated research is requested or a repo/skill needs evidence-backed research, metric tracking, or safe…
Skill Codex needs its repo
Run structured AI code review as an advisory closeout gate for local diffs, PR branches, or commits when the user asks for autoreview, Codex review, second-model review, or pre-ship validation.
Skill Claude CodeCodex
Review, create, and validate Bash scripts when shell work needs strict mode, quoting safety, portability, or interpreter-compatible behavior.
Skill Claude CodeCodex
Analyze, fix, and validate Biome linting workflows. Use when JavaScript or TypeScript projects need Biome commands, diagnostics, safe fixes, or CI lint gates.
Skill Codex
Create, diagnose, and validate a local dev bootstrap. Use when the user asks to clone a repo, install toolchains, install dependencies, and prove the project runs.
Skill Codex
Turn Slack #code-fixes, CodeRabbit, Codex Review, CI, and check-status noise into a repo-and-PR action queue. Use when Jamie asks for a daily code-fixes digest, recent review-noise triage, or what needs fixing across active engineering repos.
