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 probe-agent web-researcher (list with ./install.sh --list).

Claude Code

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>

Gemini CLI

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

opencode

Agents

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

Skills

npx skills add uwuclxdy/agenticat -a opencode

Codex CLI

Agents

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

Skills

npx skills add uwuclxdy/agenticat -a codex

Cursor

Agents

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

Skills

npx skills add uwuclxdy/agenticat -a cursor

anything else (73+ harnesses)

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 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-code-reviewer, ts-code-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
threat-modeling	original	threat-modeling-expert	STRIDE and attack trees, each requirement mapped to a mitigation
bash-defensive-patterns	wshobson	shell-pro	defensive idioms for scripts that mutate live systems
bats-testing-patterns	wshobson	shell-pro	testing shell scripts with bats-core, error paths included
shellcheck-configuration	wshobson	shell-pro	minimal .shellcheckrc where every disable carries its reason; CI gating included

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

External skills

Third-party skills worth checking out. use --skill to cherry pick them, so your setup doesn't get bloated.

skill	source	license	used by	install
systematic-debugging, test-driven-development, verification-before-completion	obra/superpowers	MIT	standalone	npx skills add obra/superpowers --skill <name>
webapp-testing	anthropics/skills	Apache-2.0	webapp-tester	npx skills add anthropics/skills --skill webapp-testing

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-code-reviewer	inherit	clean-code	read-only Python diff/PR review with file:line and severity
ts-code-reviewer	inherit	clean-code	same for TypeScript and JavaScript
doc-coverage-audit	inherit	none	before deleting a doc, checks nothing it covers gets dropped
docs-extractor	inherit	none	digests a file or doc set into a brief, keeps raw bytes out of your context
spec-propagation	opus	none	folds a decided spec into a design doc in that doc's own voice
threat-modeling-expert	opus	threat-modeling	STRIDE and attack-tree threat model, writes one doc
probe-agent	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 (ext)	drives a local app via Playwright, reports pass/fail with screenshots
shell-pro +	inherit	bash-defensive-patterns, shellcheck-configuration, bats-testing-patterns	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	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

• loads if installed is soft, has the same fallback rule as the skills table.
• + began as wshobson/agents personas (MIT), rewritten and debloated.

External repos checked

Repos evaluated as skill or agent sources. Adopted ones are marked; the rest were passed over for the reason given.
