Searches code by AST patterns and performs structural refactoring across files. Use when finding function calls, replacing code patterns, or refactoring syntax that regex cannot reliably match.

Initializes projects, manages dependencies, runs scripts, executes tests, and bundles code using Bun. Use when working with package.json, installing packages, running dev servers, or building for production.

Maps codebase structure, queries symbols, traces call paths, and analyzes dependencies. Use when exploring unfamiliar code, finding function callers/callees, detecting circular imports, or generating project overviews.

Writes and reviews Conventional Commits commit messages (v1.0.0) to support semantic versioning and automated changelogs. Use when drafting git commit messages, PR titles, release notes, or when enforcing a conventional commit format (type(scope): subject, BREAKING CHANGE, footers, revert).

Designs software systems with SOLID principles, DRY/KISS/YAGNI, and security by design. Use when planning features, analyzing requirements, defining architecture, or making architectural decisions.

Analyzes and organizes content by extracting key insights and structuring information by topic. Use when summarizing articles, processing feeds, creating topic-based reports, or distilling large content into actionable summaries.

Lints JavaScript and TypeScript code, configures rules, and fixes issues automatically. Use when linting code, fixing style issues, configuring eslint.config.js, or enforcing code quality standards.

Interacts with GitHub repositories, issues, pull requests, releases, and gists using the gh CLI. Use when managing GitHub resources, searching code/repos, creating PRs/issues, or making API requests.

Converts CLI output to JSON for structured processing and analysis. Use when parsing ps, dig, netstat, ls, or other command output into machine-readable format for piping to jq or scripts.

Finds duplicate code blocks and analyzes duplication metrics across files. Use when identifying copy-pasted code, measuring technical debt, or preparing for refactoring.

Manages version control with Jujutsu (jj), including rebasing, conflict resolution, and Git interop. Use when tracking changes, navigating history, squashing/splitting commits, or pushing to Git remotes.

Finds unused dependencies, files, and exports in JS/TS projects. Use when cleaning up dead code, removing stale packages from package.json, or identifying unreferenced exports.

Switches NixOS/Home Manager configurations, cleans old generations, and performs system maintenance. Use when running os/home switch, pruning the Nix store, or managing system generations.

Creates reproducible builds, manages flake inputs, defines devShells, and builds packages with flake.nix. Use when initializing Nix projects, locking dependencies, or running nix build/develop commands.

Runs packages temporarily, creates isolated shell environments, and evaluates Nix expressions. Use when executing tools without installing, debugging derivations, or working with nixpkgs.

Writes, edits, and renders nomnoml diagrams (text-to-UML) for architecture sketches, class diagrams, sequence-like flows, and relationship graphs. Use when asked to create or update nomnoml code, convert a description into a diagram, or render nomnoml to SVG/PNG for docs.

Processes structured data through pipelines, filters tables, transforms JSON/CSV/YAML, and defines custom commands. Use when scripting with typed parameters or working with tabular data.

Configures pi coding agent with skills, templates, extensions, packages, and models. Use for composable development workflows, custom agents, and project-specific configurations.

Manages containers, builds images, configures pods and networks with Podman. Use when running containers, creating Containerfiles, grouping services in pods, or managing container resources.

Structures Python projects, writes type-hinted code, tests with pytest, and enforces quality with ruff and mypy. Use when setting up pyproject.toml, writing tests, adding type annotations, or formatting/linting code.

Fetches web pages, parses HTML with CSS selectors, calls REST APIs, and scrapes dynamic content. Use when extracting data from websites, querying JSON APIs, or automating browser interactions.

Writes effective pi skills with proper structure, concise content, and progressive disclosure. Use when creating new skills, improving existing skills, or reviewing skill quality.

Applies software engineering best practices, design principles, and avoids common anti-patterns. Use when designing systems, reviewing code quality, refactoring legacy code, making architectural decisions, or improving maintainability.

Manages background processes, captures command output, and handles session multiplexing. Use when running long-running commands, capturing output from detached processes, or managing concurrent tasks in headless environments.

Converts JSON to compact TOON format for reduced token usage. Use when inspecting JSON APIs, processing large JSON payloads, or reducing token costs when sending data to LLMs.

Configures TypeScript projects, defines types and interfaces, writes generics, and implements type guards. Use when setting up tsconfig.json, creating type definitions, or ensuring type safety in JS/TS codebases.

Initializes Python projects, manages dependencies, pins Python versions, and runs scripts with uv. Use when adding/removing packages, syncing environments, running tools with uvx, or building distributions.

Builds Vicinae launcher extensions with TypeScript and React, defines commands, and creates List/Form/Detail views. Use when creating new extensions, implementing view/no-view commands, or building Raycast-compatible extensions.

Writes and runs tests, configures test environments, mocks dependencies, and generates coverage reports. Use when setting up vitest.config.ts, writing test suites, mocking modules, or measuring code coverage.

Downloads videos from YouTube and other sites using yt-dlp. Use when downloading videos, extracting metadata, or batch downloading multiple files.
