Install

Skills CLI

npx skills add jMerta/codex-skills

Asks which skills and agents to install. Just one: npx skills add jMerta/codex-skills --skill branch-cleaner — add -g for every project.

Claude Code

git clone https://github.com/jMerta/codex-skillscp -r "codex-skills/branch-cleaner" ~/.claude/skills/

Copies the branch-cleaner skill into ~/.claude/skills/ for every project (use .claude/skills/ for one project). Repeat for the other skills listed below.

Plugin

/plugin marketplace add jMerta/codex-skills

Run inside Claude Code if the repository ships a plugin marketplace, then pick plugins from /plugin.

Skills can run code on your machine — read the SKILL.md first.

What it does

In the author's own words, from each skill's SKILL.md.

  • branch-cleaner

    Use when the user asks to list, audit, prune, or delete local or remote Git branches, especially stale, merged, gone-upstream, protected, worktree-bound, or open-PR branches. Identifies safe candidates and performs only explicitly authorized cleanup.

    branch-cleaner/SKILL.md on GitHub (opens in a new tab)
  • bug-triage

    Use when the user reports a bug, regression, runtime error, failing build, or broken test and wants reproduction, diagnosis, root-cause analysis, or an authorized fix. Isolates the shared cause and verifies the smallest relevant change.

    bug-triage/SKILL.md on GitHub (opens in a new tab)
  • ci-fix

    Use when the user asks to diagnose or fix failing GitHub Actions checks on a pull request, branch, or workflow run, or wants CI log and root-cause analysis. Prefers GitHub connector context, uses gh for Actions logs, and verifies authorized fixes locally.

    ci-fix/SKILL.md on GitHub (opens in a new tab)
  • commit-work

    Use when the user asks to stage changes, create a Git commit, split work into logical commits, or craft a commit message. Inspects the worktree, preserves unrelated changes, stages only intended files or hunks, and follows repository conventions.

    commit-work/SKILL.md on GitHub (opens in a new tab)
  • create-pr

    Use when the user asks to prepare, publish, or open a GitHub pull request from a local checkout. Verifies branch and diff scope, runs relevant checks, creates needed commits, pushes only when authorized, and opens a truthful draft or ready PR.

    create-pr/SKILL.md on GitHub (opens in a new tab)
  • dependency-upgrader

    Use when the user asks to update, bump, or migrate Java, Kotlin, Gradle, Maven, Node, or TypeScript dependencies; audit direct or transitive dependencies for CVEs or security advisories; or remediate a dependency vulnerability. Preserves the package manager, applies small verified upgrades, and checks vulnerability, release-age, and supply-chain risk.

    dependency-upgrader/SKILL.md on GitHub (opens in a new tab)
  • docs-sync

    Use when the user asks to update documentation after code or configuration changes, audit documentation drift, or prepare README, API, runbook, or release docs. Changes only affected documentation and verifies examples, links, contracts, and operational steps against source code.

    docs-sync/SKILL.md on GitHub (opens in a new tab)
  • focused-tdd

    Use when the user asks for test-first development, TDD, or a regression test before a fix, or when implementing deterministic business rules, state transitions, authorization boundaries, idempotency, and other behavior where observing a focused failing test would materially reduce risk. Selects strict TDD, regression-first, or proportional validation.

    focused-tdd/SKILL.md on GitHub (opens in a new tab)
  • manage-product-ideas

    Use when the user asks to capture, clarify, document, audit, generate, compare, prioritize, validate, or realize product ideas. Guides one-question-at-a-time discovery, evidence-based scoring, explicit readiness decisions, and scoped delivery without assuming a specific product, repository layout, or planning plugin.

    manage-product-ideas/SKILL.md on GitHub (opens in a new tab)
  • pr-visual-explainer

    Use when the user asks to explain a pull request visually, create an HTML walkthrough, show before-and-after behavior, or add diagrams for a PR. Triggers automatically for requests such as "explain this PR" when a visual artifact would materially improve understanding; does not run merely because a PR was created.

    pr-visual-explainer/SKILL.md on GitHub (opens in a new tab)
  • rebase-assistant

    Use when the user asks to rebase or update a Git branch onto another ref, handle rebase conflicts, or verify rewritten history. Protects dirty worktrees, resolves conflicts by intent, and keeps force-push as a separate authorized action.

    rebase-assistant/SKILL.md on GitHub (opens in a new tab)
  • regex-builder

    Use when the user asks to create, debug, explain, validate, or optimize a regular expression or replacement for a specific engine. Verifies representative matches, non-matches, captures, escaping, portability limits, and backtracking risk in the target runtime.

    regex-builder/SKILL.md on GitHub (opens in a new tab)
  • release-notes

    Use when the user asks to draft release notes, changelog entries, or GitHub Release text from commits, tags, branches, or merged pull requests. Resolves an exact Git range and surfaces breaking changes, migrations, security impact, and upgrade steps.

    release-notes/SKILL.md on GitHub (opens in a new tab)
  • review-architecture-scope

    Use when the user asks for a pre-PR or diff review of changes crossing application, API contract, runtime, tenant, deployment, infrastructure, observability, or intended-outcome boundaries. Traces producers, consumers, compatibility windows, asynchronous context, rollout paths, and scope without treating diff size as risk.

    review-architecture-scope/SKILL.md on GitHub (opens in a new tab)
  • review-backend-change

    Use when the user asks for a pre-PR or diff review of backend controllers, APIs, domain services, authorization, tenant context, jobs, transactions, repositories, SQL, ORM or mapper code, schema migrations, constraints, indexes, or backfills. Reviews reachable domain, persistence, and rollout regressions across the full call chain.

    review-backend-change/SKILL.md on GitHub (opens in a new tab)
  • review-frontend-change

    Use when the user asks for a pre-PR or diff review of frontend API clients, authentication requests, cache or query keys, DTO decoding, normalization, components, copy, localization, responsive layout, accessibility, modals, navigation, or visual evidence. Reviews reachable data-flow and UI regressions using the owning application's actual contracts.

    review-frontend-change/SKILL.md on GitHub (opens in a new tab)
  • review-security-privacy

    Use when the user asks for a pre-PR or diff security and privacy review, especially for authentication, authorization, tenant isolation, public endpoints, webhooks, payments, secrets, logs, personal data, files, exports, or observability access. Reports only reachable regressions introduced or materially changed by the diff.

    review-security-privacy/SKILL.md on GitHub (opens in a new tab)
  • review-test-coverage

    Use when the user asks for a pre-PR or diff review of tests, CI evidence, test harness changes, screenshots, recordings, or proportional validation. Finds reachable behavior that the changed tests or evidence fail to protect, separates code defects from external CI outages, and recommends the narrowest meaningful check.

    review-test-coverage/SKILL.md on GitHub (opens in a new tab)
  • vps-checkup

    Use when the user asks for a read-only health, security, network exposure, update, backup, or Docker audit of an Ubuntu VPS over SSH. Produces an evidence-based report and requires explicit approval before package refreshes, configuration changes, restarts, pruning, or reboot.

    vps-checkup/SKILL.md on GitHub (opens in a new tab)
  • write-ui-copy

    Use when the user asks to draft, rewrite, translate, or review user-facing interface copy in Polish or English, including titles, descriptions, buttons, links, labels, hints, toasts, errors, empty states, statuses, payment messages, and confirmations. Aligns meaning when both supported locales are in scope.

    write-ui-copy/SKILL.md on GitHub (opens in a new tab)

Review before you install

A skill is a set of instructions and scripts your agent will follow, and it can run code on your machine. Read the SKILL.md and any scripts first — this listing is not a security review.
