tdd
Comprehensive guide for Test-Driven Development (TDD) methodology. Use this skill when the user asks to implement features using TDD, write tests first, follow red-green-refactor cycle, or develop code with test-first approach. Also use when user mentions TDD, unit testing workflow, or wants to refactor code with test coverage.
agents-md-review
Review a PR/diff for whether it makes the repo's AGENTS.md or CLAUDE.md stale, and audit those two files for anti-patterns (generic filler, tools named without runnable commands, stale paths). Classifies the change's materiality High/Medium/Low and demands an instructions update for High. Use as the AGENTS.md reviewer in a review panel, or when asked whether a change needs an AGENTS.md/CLAUDE.md update.

claude-code-session-tracker
Append unfinished Claude Code sessions to a tracker file so they can be resumed via `claude --resume "<session name>"`. Trigger when user signals ending ("done for now", "wrap up", "goodbye"), hits rate/context limit, or asks to save/track the session. Skip short one-offs, clean completions, or trivial Q&A.
codify-writing
>-
create-video-recording
Create PR-ready video verification artifacts for UI, report, browser, visual, or human-reviewable changes. Use when the user asks to record a demo, create a video recording, demo this, make a verification video, produce proof for a PR, prepare the PR Verification section, or when a change is demoable before review. Also use before `gh pr create` for product-visible changes and when building verification reports that should embed or link to a demo video.
eat-like-japanese-local-foodie
Research restaurants the way local Japanese foodies would. Use when Codex needs to find, compare, rank, or document what to eat in Japan for a trip, especially when the user asks for local Japanese recommendations, foodie picks, Tabelog, Hyakumeiten, Michelin Japan, Japanese beef, ramen, coffee, cafes, family-friendly meals, or Japan city/area food surveys.
explain-diff
Use when the user asks for a rich explanation of a code change, diff, branch, or PR — "explain this diff/PR/change", "walk me through what changed", "help me understand this branch". Produces a single self-contained interactive HTML explainer (background → intuition → code walkthrough → quiz). Geoffrey Litt's /explain-diff prompt, verbatim.
goal-audit
Audit a goal against the six qualities of a well-formed goal and rewrite it if it falls short. Triggers whenever the user states a goal, objective, or "what done looks like" for a task — phrases like "the goal is", "I want to", "make this better", "my objective is", "get X working", "build/fix/improve Y" — and whenever the user runs /goal-audit. Use this BEFORE starting work on any non-trivial task so the goal is auditable and has a real finish line, not just when the word "goal" appears. A vague goal gives no completion condition; this skill catches that early.
learn-quiz
Teacher mode after the agent has done work in a session. Verifies the human deeply understands what was done — problem, solution, design decisions, edge cases, broader impact — via incremental restating, gap-filling, and AskUserQuestion quizzes, tracked in a running checklist doc. Use when the user says "teach me this session", "make sure I understand", "quiz me on what you did", "/learn-quiz", or wants to learn from the work just completed. Session should not end until understanding is demonstrated.
live-review
Review an HTML file from Claude with inline comments. Spins up a Claude Code custom channel that serves the HTML with a commenting widget; the reviewer's comments are pushed into a dedicated reviewer Claude session that edits the file and replies in-page. Use when the user produces or has an HTML report/draft/output and wants to comment on it, mark it up, or iterate on it visually — triggers on "review this HTML", "let me comment on", "open for review", "live review", or finishing a draft HTML file. Also triggers whenever the user asks to "create an HTML" (or build/generate/make an HTML file/page/report): after producing it, proactively SUGGEST opening it in live-review — offer the command, don't auto-launch.
loose-ends
End-of-session cleanup sweep. Triggers when the user signals they're wrapping up — "what else to wrap up before I end", "wrap up", "done for now", "anything left", "before I end", "loose ends", "clean up". Sweeps for uncommitted/unpushed work, stale branches & worktrees, leftover files & dev processes, ssh-key state, unverified changes, and unsaved knowledge — auto-doing the safe checks, asking before anything that could lose work.
persona-reader-site
Build a single-file reading site for any person or company from their tweets (ranked by engagement) and long-form writing (blogs, Medium, RSS). Use when the user says "build/refresh a reader site for <person/company>", "scrape <handle>'s tweets and writing into a site", "make Karpathy's writing easier to read", "turn <someone>'s posts into a mini site", or wants a personal index of someone's public output. Backed by Camoufox (stealth Firefox) + a logged-in X profile.
pr-review
Single entry point for reviewing a PR, diff, or branch. Owns the goal-conformance pass — does this achieve its stated purpose, for every input, not just do the lines look fine — and dispatches specialist reviewers (complexity, security, AGENTS.md staleness) in parallel as subagents, then merges everything into one report. Use when reviewing a pull request, diff, or branch, especially when the change instruments, transforms, routes, or tags data over a set of inputs, or claims to do something "for all X".
pr-work-log
Surface off-PR work on the pull request as a maintained comment. Triggers when, while a PR is open, you do work tied to that PR that the diff does NOT show — dispatching/watching GitHub Actions runs, running a backfill/migration/data job, writing to a database, kicking off manual workflows, validation runs, or anything happening in CI/Actions/a DB/an external system. Keeps a single "Off-PR work log" comment up to date as each step lands.
reflection
Interrogate your own just-completed work with three questions — what you're least confident about, what you claimed works but never verified, and the biggest thing you're probably missing. Use when the user runs /reflection, says "reflect on that", "check yourself", or after finishing a non-trivial chunk of work where confident-but-wrong is a real risk.
ship-vercel-app
Deploy a local web app idea from this Mac to production using a new GitHub repository and Vercel GitOps. Use when the user asks to ship, launch, deploy, productionize, or publish a local app/site from ~/code or another local folder, especially with GitHub, Vercel, custom domains, Cloudflare DNS, or "from this Mac mini to production".

use-browser
Default protocol for browser automation. Load this skill FIRST whenever any task requires opening a browser, reading a webpage, filling a form, clicking buttons, taking screenshots, scraping data, or any web interaction.
