skills

A third-party marketplace of language-agnostic AI workflow plugins. Plugins install into Claude Code and Codex, and are readable by agents scanning .agents/skills/.

Warning: Review plugins before installing. Anthropic does not control plugin contents and cannot verify they work as intended.

Repository: tony/skills

Plugins

Plugin	Category	Description
commit	Development	Create git commits following project conventions with format enforcement and safety checks.
weave	Development	Run independent, adversarial AI participants via sub-agents or model CLIs to brainstorm, refine, plan, execute, architect, review, and synthesize.
rebase	Development	Automated rebase onto trunk with conflict prediction, resolution, and quality gate verification.
changelog	Productivity	Generate and maintain categorized changelog entries from branch commits and PR context.
tdd	Testing	TDD bug-fix workflow: reproduce bugs as failing tests, determine root cause, fix, and verify.
model-cli	Development	Run prompts through individual AI CLIs — Antigravity/agy (Gemini), codex/GPT, and cursor/agent with fallback support.
pr	Development	Manage gold-standard PR descriptions. Detects AI slop and verbose commits, resolving them via fixup commits and autosquash.
research	Learning	Study dependencies locally. Clones upstream repos and creates version-pinned worktrees matching your project's exact versions.
slop	Development	Scan tracked files for AI slop and verbose noise, resolving each finding with atomic, verified commits.
tailwind	Design	Detect and fix inconsistent spacing, margin/gap mixing, and padding asymmetry in Tailwind CSS layouts.
pytest-optimizer	Testing	Profile and optimize pytest suites. Ranks and applies safe speedups as verified, independent commits.
spike	Development	Run no-commit spikes, strategy bakeoffs, or multi-round convergence in git worktrees. Tests ideas against quality gates and returns a commit-by-commit implementation plan.
respond	Development	Screen review feedback from humans or bots before changing code. Verifies claims against facts and project decisions. Valid findings become gated, atomic commits; invalid ones get evidence-backed replies.
action	Development	Convert tickets to branches in isolated worktrees. Uses team branch conventions, lands gated commits, and supports parallel tickets.
lean	Development	Writing discipline and cleanup tools for tight, slop-free prose and code.
double-check	Productivity	Forces verification requests to return re-derived answers instead of diffs against prior turns. Includes an alignment tool for repairing chats.
release	Development	Cut and bump releases with safe defaults (no automatic push/tag). Rolls out releases to downstream consumers with CI verification.
merge-pr	Development	Merge PRs matching repo history conventions. Includes readiness checks, CI watching, stack detection, and automated rebasing.
business	Productivity	Measure and report the business value of AI workflows with provenance-tagged data — metrics in engineer-hours and cycle time, never currency.
disk	Productivity	Safely reclaim disk space. Classifies consumers as cache, redundant copy, or history, deleting only what is proven safe.
github-actions	Development	Update GitHub Actions pins fleet-wide. Verifies tags, researches release notes, commits each action separately, and supersedes Dependabot PRs.
situate	Development	Gain situational awareness before modifying code. Scans branches, PRs, tickets, and project conventions to orient the agent and verify the work required.
terraform	Development	Upgrade Terraform and OpenTofu versions. Discovers every root module, moves provider constraints together because they combine across modules, and refreshes lock files.
ruff	Development	Upgrade Ruff across repositories. Works out which new rules can fire against each repo's select list and lands one reviewed commit per rule, citing the upstream rule doc.
git-branch	Development	Rebuild branch history into atomic commits (byte-identical), or reimplement from scratch using existing tests as the spec. Includes an interactive-rebase toolkit.
package-updater	Development	Update dependencies and toolchains across repositories. Checks the supply-chain cooldown first, then commits toolchain, named bumps, and lockfile refreshes separately with release notes cited.
gh	Development	File durable GitHub issues with reproductions, pinned links, and stripped PII. Enforces a markdown writing discipline reusable for any PR, comment, or ticket.
self-improvement	Development	Mine local agent prompt history for how the skill catalog is really used, then land the changes that usage evidence supports.
ticket	Development	Manage work across trackers (Linear, Jira, GitHub, etc.) respecting each platform's native object graph. Drafts durable tickets focused on invariants.

Installation

Claude Code

Add the marketplace:

/plugin marketplace add tony/skills

You can also browse available plugins with /plugin > Discover.

Then install any plugin by the name in the table above:

/plugin install commit@skills

Codex

Add the marketplace:

codex plugin marketplace add tony/skills

Then install any plugin by the name in the table above:

codex plugin add commit@skills

Each workflow is one skill, invoked as pr:deslop under Codex and /pr:deslop under Claude Code.

Design Philosophy

All plugins are language-agnostic. Instead of hardcoding language-specific tools (e.g., pytest, jest, cargo test), they dynamically read project conventions from AGENTS.md or CLAUDE.md to discover:

• Test suite, linter, formatter, and type checker commands
• Commit message formats
• Test patterns

This ensures compatibility across languages like Python, TypeScript, Rust, and Go.

Development

Scripts use uv to manage Python dependencies.

Install uv:

curl -LsSf https://astral.sh/uv/install.sh | sh

or:

wget -qO- https://astral.sh/uv/install.sh | sh

See uv installation docs for other methods.

Lint and validate

uv run ./scripts/marketplace.py lint

Sync marketplace manifest with plugin directories

Dry-run:

uv run ./scripts/marketplace.py sync

Write changes to marketplace.json:

uv run ./scripts/marketplace.py sync --write

Check for outdated entries

uv run ./scripts/marketplace.py check-outdated

Regenerate the portable skill export

.agents/skills/ is a generated, flattened mirror of every plugin skill for agents outside Claude Code (Cursor, pi, Antigravity, Grok). It contains spec-only frontmatter with no host-specific inline-bash expansion. Files are copied and links rewritten to make each exported skill self-contained.

Codex reads skills/ in place and consumes plugins directly via .codex-plugin/plugin.json.

uv run ./scripts/marketplace.py portable

Verify the committed tree matches the generated plugins:

uv run ./scripts/marketplace.py portable --check

• Edit: plugins/*/skills/
• Do not edit generated files: .agents/skills/, .agents/plugins/, or plugins/*/.codex-plugin/

.agents/portable-manifest.json tracks exported skill sources and bundled files.

Hosts scanning .agents/skills/ read the tree directly. The skills CLI also reads this tree:

npx skills add tony/skills

This installs only the export. The metadata.pluginRoot in the marketplace manifest prevents duplicate skill renderings from being exposed.

Code quality for scripts

Lint:

uv run ruff check ./scripts/

Format check:

uv run ruff format --check ./scripts/

Type check:

uv run basedpyright ./scripts/
