▸ Agent Skills

Tooling

Environments, CLIs, and agent conventions.

Sections

  • agent-guidelines — Behavioural guidelines for AI agents to reduce common LLM coding mistakes. Use before and while implementing to avoid common LLM coding pitfalls - over-engineering, unrequested refactors, silent assumptions, and unverified changes.
  • antigravity — Provides a comprehensive guide, quick reference, and sitemap for Google Antigravity (AGY), including the Antigravity CLI (agy), Antigravity 2.0, Antigravity IDE, Python SDK, slash commands, keybindings, and customizations (skills, rules, MCP, sidecars). Activate this skill when the user asks questions about how to use, configure, or customize Antigravity, AGY, the agy CLI, the Antigravity IDE, or Antigravity 2.0.
  • cargo-crap — Measure and gate Change Risk Anti-Patterns (CRAP) metric across Rust codebases by combining cyclomatic complexity with test coverage. Use when evaluating code maintainability, gating CI against complexity regressions, setting up cargo-llvm-cov with cargo-crap, or generating shields.io badges for Rust projects.
  • cargo-doc — Generate, query, and navigate local Rust documentation and docs.rs with zero hallucination. Use when researching Rust crate APIs, verifying struct and trait signatures, inspecting conditionally compiled feature flags, finding methods on types, or searching offline docs when internet or llms.txt is unavailable.
  • devenv — Strict guidelines for using devenv for shell and dependency management. Use when a repo contains a devenv.nix or devenv.yaml file, or when running commands in a devenv environment.
  • herdr — Control Herdr terminal multiplexer, manage workspaces, tabs, and panes, coordinate coding agents, or guide humans on installing, configuring, and troubleshooting Herdr. Use when working inside Herdr (HERDR_ENV=1), orchestrating agent terminal sessions, or assisting users with Herdr concepts, setup, and keybindings.
  • install-skills — Install, update, and manage agent skills from a GitHub-hosted collection with the skills.sh CLI (`npx skills add <owner>/<repo>`), across every runtime the collection targets - Claude Code, OpenCode, Goose, and Antigravity CLI. Use when adding skills to an agent, updating a stale copy, verifying an install, wiring the same collection into another runtime, or troubleshooting a skill that will not show up or that collides by name.
  • nix-shell — Run CLI utilities and diagnostic tools in ephemeral Nix shells when a required binary is missing from PATH. Use when a command or tool is not found, when running one-off inspection or data-processing tools (such as jq, ripgrep, ffmpeg, tree, pandoc, or curl) on systems with Nix installed, or when the user asks to run something in a nix shell.
  • opencode — This skill provides comprehensive guidance for using OpenCode, the open-source AI coding agent. Use this skill when working with OpenCode CLI commands, keyboard shortcuts, agents (build/plan), slash commands, tools, skills, MCP servers, or configuration. Automatically triggered when OpenCode-specific questions or tasks are detected.
  • opencode-acp — Control OpenCode directly via the Agent Client Protocol (ACP). Start sessions, send prompts, resume conversations, and manage OpenCode updates. Use when driving OpenCode headless or programmatically over ACP - starting a session, sending prompts, resuming a prior session, or checking and triggering OpenCode updates.
  • pagefind — Use when configuring, indexing, or troubleshooting Pagefind static search for websites. Covers config options, CLI flags, and client integrations.
  • prek — Run pre-commit hooks using the prek CLI tool. Differentiates between 'pre-commit' (the git hooks concept/lifecycle stage) and 'prek' (the actual binary command; pre-commit CLI is deprecated, use prek). Use when you need to run, configure, check, or troubleshoot git pre-commit hooks.
  • scratchpad — Keep one-off, experimental, or temporary scripts and files out of the source tree by writing them to a single, consistent session scratch location, then cleaning them up. Use when creating throwaway, experimental, or temporary scripts/files during a task.
  • tailwind — Use when writing Tailwind CSS utility classes, compiling Tailwind bundles, or configuring Tailwind CSS v4 CSS-first themes and variables.
  • tars-run-factory — Run the TARS software factory unattended over one repository's backlog. The agent becomes the foreman: it drives the Antigravity CLI (agy) headlessly through batch runs, peer reviews, and rework until the backlog drains or a human is needed.
  • tauri — Expert reference and development guidelines for Tauri v2+ cross-platform desktop and mobile apps. Use when the user mentions Tauri, src-tauri, tauri v2, tauri.conf.json, or capabilities.json, or asks to build, modify, or debug Tauri application settings, IPC commands, or capabilities.
  • zed — Find, search, and manage Zed editor configuration settings, keybindings, and language server configurations. Use when configuring Zed settings, creating or updating ~/.config/zed/settings.json or .zed/settings.json, editing keymap.json, or searching for Zed options and documentation.
  • zola — Expert reference and development guidelines for the Zola static site generator. Use when the user asks to modify, build, serve, or customize Zola sites, themes, templates, shortcodes, or Zola configuration files (such as config.toml).
