Skills (12)

• agentic-walkthrough

  Prove that a reported run caused its intended real effect. Walk the executor path from entry to effect, capture one observable per hop, and report a result a no-op could not produce.

• charter

  Write, revise or review a charter: the one document that tells an executor what to deliver, what is out of bounds, what the owner already decided, and how each success check will be proven. Use when work needs a written brief before someone else does it, or when asked to write, change or check a cha

• e2e-environment-preflight

  Check external services, hosts, browser sessions, model endpoints, and agents before an end-to-end run. MANUAL-ONLY: load when a caller names it. NEVER auto-load from context for ordinary testing or debugging.

• e2e-red-triage

  Classify one unexpected end-to-end test failure as a product defect or an environment fault needing a new preflight check. MANUAL-ONLY: load when the suite runner names a specific failure. NEVER auto-load from context.

• first-principles-review

  MANUAL-ONLY: challenge a product idea, design, PRD, or architecture from first principles. Use only when the user names this skill. Research first, then write a local review and PRD handoff.

• less-is-more

  Write the least code that works, and cut what an AI agent over-built. Use on any coding task: write, fix, refactor, or review a diff. Also when the user says 'less', 'simplify', 'too complex', 'over-engineered', or 'what can we delete'. Not for prose, research, or non-code questions.

• owner-intent-audit

  Check agent-produced plans, tests, or code against the owner's actual intent. Find missing meaning, unrequested work, stale truth, unreachable decisions, unsupported completion claims, and implementation debt. Use before approval or merge.

• python-coder

  Implement and refactor production Python, FastAPI, Pydantic, async, and migrations.

• rust-coder

  Implement, refactor, and migrate production Rust with repository-grounded ownership, type-driven invariants, explicit errors, safe concurrency, minimal unsafe code, and verified Cargo workflows. Use for Rust features, crates, CLIs, services, libraries, async code, FFI, performance work, migrations,

• shellscript-coder

  Implement and refactor production shell scripts, command-line tools, automation, process wrappers, and Git or infrastructure helpers with reliable failures, useful logs, and machine-readable output.

• test-writer

  Write and improve test-owned code: tests, test scripts, fixtures, evals, and test-only helpers. Use whenever Codex is asked to create or change test code. Its only job is to produce the strongest practical tests in the repository's existing harness, run them, and fix defects in the test code.

• ts-coder

  Implement and refactor production TypeScript/TSX, strict types, APIs, and migrations.
