Coding & Dev Tools
Coding agent skills teach AI agents repeatable engineering workflows: reviewing pull requests, writing tests, refactoring safely, and enforcing house style. Install one SKILL.md and your agent applies the same checklist every time, whether you use Claude Code, Cursor, Codex, or another agent.
-
al-janef Bundle Performance ScalabilityMeasure first, then fix latency, throughput, memory, CPU, bundle size, query count, contention, and scaling problems with before/after evidence under the same workload. Use for anything slow, expensive, or expected to scale; never optimize from intuition or trade correctness for speed silently.
-
modem-dev Skill Hunk Extensions 2Maps the `hunkdiff/extension` authoring surface for Hunk, the terminal diff viewer — hiding or reordering reviewed files, docked panes, alternate file views, commands and key bindings, dialogs, workspace writes, themes, syntax languages, VCS backends, lifecycle events. Use when writing, debugging, or installing a Hunk extension, or when a request asks Hunk itself to behave differently. Not for reviewing a diff in a live session — that is hunk-review.
-
northraystudio Skill SetupInstall the full maruda harness into the current project through a short interview: CLAUDE.md, hooks, .claude/settings.json, rules, and skill wiring. Asks — never auto-detects — the languages (Go / Python / TypeScript / JavaScript) and commands, then writes files only after an approved summary. Use when the user asks to set up / install / bootstrap maruda, the harness, or the continuous improvement cycle. Triggers: セットアップして, ハーネスを入れて, harnessを入れて, marudaを導入して, プロジェクトを初期化して, '/maruda:setup', 'set up the harness', 'install maruda', 'bootstrap this project'.

northraystudio Skill Gh Issue PlannerFetch a GitHub Issue by ID using the gh CLI, investigate related code, propose a structured response plan (policy, impact scope, implementation steps), and post the agreed plan as a comment on the issue. Implementation/PR creation is out of scope — use gh-issue-resolver for that. Use when the user provides a GitHub Issue ID or asks to investigate/analyze/plan a GitHub Issue. Triggers include issue IDs like #42 or 'issue 42', requests such as Issueを調査して / Issueの対応方針を立てて, analyze issue #N, plan issue #N, investigate issue, look at issue. Accepts several Issues at once (e.g. '1,2,3' or 'Issue 1と2を計画して'): it investigates once and posts one agreed-plan comment per Issue.
-
northraystudio Skill Gh Issue ResolverImplement and verify a fix for a GitHub Issue whose response plan has already been posted as a comment by gh-issue-planner. Creates a feature branch, applies the agreed plan, runs tests, and opens a Pull Request. Use when the user asks to implement/fix/resolve a planned GitHub Issue. Triggers include requests such as Issueを実装して / Issueを修正して / Issueを対応して, implement issue #N, fix issue #N, resolve issue #N, work on issue #N. Prerequisite: an agreed plan comment must exist on the issue (run gh-issue-planner first if not).
