sync-agenticat

Mine an external agent/skill collection and curate keepers into this repo's catalog (agents/, skills/, README links). Use when importing, adapting, or evaluating external agents, skills, or commands for agenticat.

bash-defensive-patterns

Defensive Bash for scripts that mutate live systems. Use when writing, hardening, or reviewing scripts (deploy/apply, systemd oneshot+timer units, firewall/sshd/sudoers edits, ssh remote-exec).

Testing & QA Solid

bats-testing-patterns

Bats test patterns for shell scripts and CLI tools (`.bats` files, `run`, `setup`/`teardown`, PATH-stub mocking, CI wiring). Use when adding tests to a bash/shell script, hardening its error paths, or wiring `bats-core` into CI.

Code & Development Solid

clean-code

Language-agnostic clean-code baseline: naming, functions, error handling, comments, duplication. Use before writing or reviewing code in any language, when no language-specific clean-* skill applies.

clean-rust

Clean, idiomatic Rust 2024 conventions: ownership, error handling, async, unsafe, traits, iterators, performance. Use when writing or reviewing Rust, running clippy, or checking 'idiomatic rust'.

handoff

Captures the current session into a continuation prompt for a fresh one, or resumes from a pasted handoff. Use when context is running low, when ending a session mid-task, or when told to 'hand off' or write a handoff. `/handoff reusable` instead maintains a persistent multi-session task-runner state file (`docs/handoff-state.md`) that a fresh session reads, advances a few tasks via agent pairs, and re-saves.

name-check

Suggests project/crate/plugin names and checks availability across registries (crates.io, npm, PyPI, AUR, GitHub, domains; needs `bun`). Use before naming, renaming, or publishing anything.

parity-gap

Diffs a program against a reference or spec and writes the gaps as tasks. Use when matching, catching up to, reaching parity with, or surpassing another tool. Writes the gap list into `docs/todo.md`.

Data & Documents Solid

shellcheck-configuration

ShellCheck rc-file and directive discipline. Use when adding a `.shellcheckrc`, silencing warnings (`# shellcheck disable=`), or gating CI.

threat-modeling

Threat modeling with STRIDE, attack trees, security-requirement extraction, mitigation and control-library selection (defense-in-depth), and compliance mapping (PCI-DSS/HIPAA/GDPR/OWASP-ASVS). Use when doing a security review, choosing mitigating controls, hardening a design, or building a threat-model doc.

API & Backend Solid

todo

Authors and normalizes tasks into `docs/todo.md`. Use when writing a todo list, capturing audit findings, or turning loose notes into pickup-cold-ready tasks.

clean-flutter

Clean, idiomatic Flutter/Dart conventions: feature-first architecture, Riverpod, freezed, go_router, const correctness. Use when writing or reviewing Dart, widgets, `BuildContext`, `build_runner`, or state management.

Testing & QA Solid

emulator-testing

Boots and drives Android AVDs and iOS simulators from the CLI (adb, `xcrun simctl`, Flutter `integration_test`, Alchemist goldens). Use when running headless app tests, verifying screenshots, or debugging emulator boot/GPU issues.

docs-sync

Reconciles `README`, `docs/*`, `CLAUDE.md`, and agent/skill/plugin prompt files with what the code actually does: fixes stale, missing, or overpromising claims and verifies every quoted command/flag/path. Use after a change alters documented behavior, when a tool's output shape or fields change, or to sweep all docs.

ratatui-patterns

Modern-ratatui knowledge pack for writing, refactoring, or reviewing Rust TUI code on ratatui or crossterm. Use when touching TUI widgets, layout, styling, or event loops; writing TestBackend render tests; or resolving ratatui version upgrades and API questions.

API & Backend Solid

skill-routing-audit

Audits a skill (or all skills) for routing gaps: it holds the right answer but buries it where an agent won't reach it. Targets boundary/negative probes (can it do X, what can't it do, is Y possible) that route to the how-to and miss the answer. Use after authoring or editing a skill, or to sweep all skills.

webapp-testing

Playwright toolkit for testing local web apps: write Python scripts to navigate, click, fill forms, capture screenshots, and read browser console logs against a running dev server or static HTML. Use when verifying frontend behavior or debugging UI for a local webapp.

terminal-ux

Behavior rules for command-line and terminal programs: exit codes, stdout versus stderr, TTY detection, NO_COLOR and palette choice, progress output, help conventions, destructive-action confirmation, signal and panic handling, plus TUI keyboard and screen-reader concerns. Use when writing or reviewing a CLI, a TUI, argument parsing, terminal output, prompts, or terminal color handling.

ux-patterns

Interaction-design knowledge pack for how a UI behaves: the five screen states (loading, success, error, empty, partial), form validation and submission, error copy, undo versus confirmation, progressive disclosure, plus the accessibility wiring each needs. Use when building a screen's states, wiring validation, choosing a spinner or skeleton, wording an error, or deciding between a confirmation and an undo.

askama

Askama Rust templating reference (0.16).

maud

Maud Rust `html!` macro reference (0.27).

Testing & QA Solid

clean-shell

Defensive Bash and shell script quality: strict-mode `set` flags, traps, idempotent mutation of live systems (deploy, firewall/sshd/sudoers edits, systemd units, ssh remote-exec), ShellCheck rc-file and `# shellcheck disable=` discipline, bats-core tests (`.bats`, `run`, PATH-stub mocking). Use when writing, hardening, reviewing, or testing shell scripts, or wiring shellcheck/bats into CI.
