Agents & Skills that I use, compatible with most AI coding tools

license skills agents

Everything here (should be) compatible with opencode, Claude Code, Gemini CLI, Codex CLI, Cursor and 73+ skill-compatible environments.

Skill and Agent frontmatter is in Claude Code compat format by default; use npx skills and/or bundled bun script to make them compatible with other harnesses (will do it in a better way when I decide how).

Contributions are welcome!

Install

[!NOTE] Two plugins ship separately: agents and skills. Install one or both; on opencode/codex, cherry-pick by name with ./install.sh --to opencode prober web-researcher (list with ./install.sh --list).

Agents

/plugin marketplace add uwuclxdy/agenticat
/plugin install agents@agenticat

Skills

/plugin install skills@agenticat

or cherry-pick with npx skills:

npx skills add uwuclxdy/agenticat --skill <name>

Agents

gemini extensions install https://github.com/uwuclxdy/agenticat --auto-update

[!WARNING] Gemini's extension-bundled subagents are a preview feature, verify if it works on your version.

Skills

npx skills add uwuclxdy/agenticat -a gemini

Agents

git clone https://github.com/uwuclxdy/agenticat && cd agenticat
./install.sh --to opencode

Skills

npx skills add uwuclxdy/agenticat -a opencode

Agents

git clone https://github.com/uwuclxdy/agenticat && cd agenticat
./install.sh --to codex

Skills

npx skills add uwuclxdy/agenticat -a codex

Agents

Cursor reads agents/ as claude format; copy files into .claude/agents/ or .cursor/agents/.

Skills

npx skills add uwuclxdy/agenticat -a cursor

no subagents yet.

Skills

npx skills add uwuclxdy/agenticat

Or just download into ~/.claude/skills/, but then you won't get updates.

Update

  • Claude Code: /plugin update agents@agenticat and/or /plugin update skills@agenticat (every commit is a new version)
  • Gemini CLI: automatic with --auto-update
  • opencode / Codex: ./install.sh --update pulls and reconverts what you installed
  • Skills: npx skills update

Skills

Install any skill with the same command, swapping the final name (see Install for other harnesses):

npx skills add uwuclxdy/agenticat --skill <name>

The used by column is a soft link: when an agent's task touches what a skill covers it loads that skill for the deeper method. Cherry-pick either one alone and the loader falls back to its own built-in checklist.

skill origin used by what it does
clean-code s4.codes python-reviewer, ts-reviewer language-agnostic readability and naming conventions
handoff original standalone writes a continuation prompt for a fresh session, resumes from one too
name-check original standalone proposes project or crate names, checks each for availability on registries and domains (needs bun)
parity-gap original standalone diffs your project against a reference or spec, writes the gaps as tasks (calls todo)
todo original parity-gap turns findings and loose notes into a clean docs/todo.md, each task pickup-cold ready
askama original rust-pro conventions and reference for the askama Rust templating crate
maud original rust-pro conventions and reference for the maud Rust html! macro
cargo-toml-optimization original rust-pro tunes Cargo.toml and .cargo build profiles and features for faster compiles
clean-rust original rust-pro idiomatic Rust conventions, modular: core rules plus per-domain references for errors, async, concurrency, unsafe, security, observability, testing, perf
threat-modeling original threat-modeler STRIDE and attack trees, each requirement mapped to a mitigation
clean-shell wshobson shell-pro, shell-reviewer defensive live-system idioms, .shellcheckrc discipline, bats-core testing; core rules plus a reference for each
clean-flutter original flutter-pro, flutter-reviewer idiomatic Flutter/Dart conventions, modular: core rules plus per-domain references for architecture, state management, navigation, models/serialization, testing, pitfalls, packages
emulator-testing original mobile-tester drives Android emulators and iOS simulators from the CLI: headless boot, adb/simctl primitives, Flutter test layers, screenshot verification
skill-routing-audit original standalone audits a skill for routing gaps: boundary and negative questions that bury the real answer
docs-sync original docs-reconciler reconciles README, docs, and CLAUDE.md (plus agent/skill prompt files) with what the code actually does
ratatui-patterns original ratatui-pro modern ratatui built-ins, TestBackend render tests, a version-upgrade reference pack
webapp-testing anthropics webapp-tester Playwright toolkit for testing local web apps, screenshots and console logs

origin

  • wshobson: wshobson/agents (MIT)
  • s4.codes: content from @s4.codes (TikTok) as a Claude Skill; Gemini transcribes the videos, Opus condenses them into the skill.
  • original: self-authored
  • anthropics: anthropics/skills (Apache-2.0), vendored with its LICENSE and a modification note
  • clean-rust distills the author's own Rust conventions; a dozen standout rules were re-authored after studying leonardomso/rust-skills (MIT)

External skills

Every third-party-origin item in the tables above is a copy this repo owns: the wshobson skills and -pro agents are rewrites, webapp-testing is vendored with its license, clean-code is distilled from transcripts. Installing them never pulls from the original source.

The one exception worth a look on its own: the obra/superpowers skills systematic-debugging, test-driven-development, and verification-before-completion (MIT) are not bundled here and install pristine from source with npx skills add obra/superpowers --skill <name>.

Agents

Install with the Claude Code plugin (see Install) or cherry-pick onto another harness with ./install.sh --to <harness> <name>. Every definition is canonical Claude Code frontmatter; the converter keeps a read-only agent read-only (no Write or Edit) wherever it lands.

agent model loads if installed what it does
python-reviewer inherit clean-code read-only Python diff/PR review with file:line and severity
ts-reviewer inherit clean-code same for TypeScript and JavaScript
docs-extractor inherit none digests a file or doc set into a brief, keeps raw bytes out of your context; coverage mode proves a doc safe to delete or merge
spec-propagator opus none folds a decided spec into a design doc in that doc's own voice
threat-modeler opus threat-modeling STRIDE and attack-tree threat model, writes one doc
prober haiku none runs a build, test or lint, returns pass/fail instead of the full log
web-researcher inherit none runs one research question through many searches, returns a cited markdown brief
webapp-tester inherit webapp-testing drives a local app via Playwright, reports pass/fail with screenshots
shell-pro + inherit clean-shell writes or refactors bash or POSIX sh, verifies with shellcheck
golang-pro + inherit none one module-sized Go task, proven with the repo's gate and race detector
rust-pro + inherit clean-rust, cargo-toml-optimization, askama, maud one Rust task against the repo's cargo and clippy gate
c-cpp-pro + inherit none C and C++ with explicit ownership, sanitizers wired to the repo build
flutter-pro inherit clean-flutter one Flutter/Dart task against the repo's analyze/format/test gate
flutter-reviewer opus clean-flutter read-only Flutter/Dart diff/PR review with file:line and severity
mobile-tester sonnet emulator-testing drives a local Android AVD or iOS simulator, reports pass/fail with screenshots
rust-reviewer opus clean-rust read-only Rust diff/PR review: correctness, safety, async, invariants
shell-reviewer sonnet clean-shell read-only shell/bash review: quoting, error handling, injection, portability
root-cause-investigator opus none evidence-first root-cause hunt for disputed regressions, returns a hypothesis ledger
tui-tester sonnet none drives a TUI/CLI in a real tmux pty like a user, reports pass/fail with captured screens
frontend-builder sonnet none builds self-contained single-file frontends: canvas/WebAudio demos, SVG and favicon glyphs
docs-reconciler sonnet docs-sync reconciles README, docs, CLAUDE.md, and agent/skill prompt files with the code, edits docs only
ratatui-pro sonnet ratatui-patterns one Rust TUI task with current ratatui built-ins plus TestBackend tests
  • loads if installed is soft, has the same fallback rule as the skills table.
  • + began as wshobson/agents personas (MIT), rewritten and debloated.

  • dmicheneau/opencode-template-agent: template, not an installer.
  • antfu/skills-npm: competing install-from-npm concept.
  • VintLin/skill-flow: competing cross-agent skill manager.
  • hesreallyhim/awesome-claude-code: index only, used for discovery.
