Automate web navigation, form filling, screenshots and scraping through small scripts that share persistent browser page state.
A Git expert skill that splits changes into atomic commits, drives rebase/squash safely, and digs through history with blame, bisect and pickaxe search.

Analyzes every open GitHub issue and PR in parallel and writes permalink-backed triage reports without ever mutating the repository.
Keeps watching a pull request — CI, comments, and unresolved review threads — until it's genuinely ready to merge.
An authoritative reference skill that keeps Claude API code correct — model IDs, pricing, streaming, tool use, MCP, agents, caching, token counting and migrations, per language.
Scans a repository and builds an interactive knowledge graph of its architecture, components, and relationships.
Guides Claude to write correct Astropy code for units, coordinate transforms, FITS I/O, tables, time scales, WCS, and cosmology.
Runs a long-horizon experiment loop that improves a code/model/prompt artifact against an evaluator, using a persistent hypothesis tree and a held-out test merge gate to avoid overfitting.
A hands-on playbook for validating web accessibility with VoiceOver, NVDA, JAWS and TalkBack.
Turns Claude into an explore-first planning consultant that grounds in your codebase, asks only the decisions you must own, and — only after your explicit okay — writes one decision-complete work plan.
A post-implementation review gate that spawns five parallel sub-agents — goal verification, hands-on QA, code quality, security, and context mining — and passes only if all five pass.
A four-language engineering constitution that forces reference reading before coding, then enforces strict types, TDD, and file-size discipline.
Scans a repository and auto-generates a hierarchical set of AGENTS.md files at the root and in complexity-scored subdirectories.
Search and refactor code by syntax structure (AST) instead of text across 25 languages, with dry-run-first codemods.
A planning-only skill that grounds in your codebase, asks just the decisions you must own, and writes one decision-complete work plan after your explicit approval.
Token-efficient codebase navigation that uses tree-sitter AST parsing to map structure first and only unfold the symbols you actually need.
