Dev & Coding

A reference skill that enforces PostgreSQL best practices for schema, data types, indexes, constraints, and partitioning.

Vets any performance number with seven evidence-based questions before you report it or act on it.

Guides Claude to port C/C++, Python, Go, or JS/TS code into idiomatic Rust while preserving the original observable behavior.

A distilled rule set that makes Claude write, review, and refactor Rust in idiomatic, robust, maintainable style.

A skill that designs REST/GraphQL APIs end to end — resource modeling, OpenAPI 3.1 specs, pagination, errors, and versioning.

A principal-architect skill that walks you from requirements to architecture diagrams and ADRs with explicit trade-offs.

A skill for designing and building command-line tools with commander, click, typer, or cobra — argument parsing, progress UI, and shell completions included.

Turns a list of shell commands into polished animated terminal demo GIFs using VHS recordings.

Evidence-driven diagnosis and repair of repository setup, plus guarded Git sync, commit, push and hook workflows.

Give it an issue number and it runs the whole loop: analyze, branch, implement, test, and open a PR.

Delegates coding, code review, and plan review to the OpenAI Codex CLI from inside Claude Code, with disciplined sandbox levels.

Reviews GitHub pull requests with seven parallel specialist subagents, then adversarially verifies every finding so only high-confidence, high-severity issues get posted.

A diagnose-first skill for writing, reviewing and debugging Terraform/OpenTofu code, tests, CI pipelines and state operations with version-aware guardrails.

Build, test and drive iOS apps in the Simulator with 31 token-efficient scripts that navigate by accessibility label instead of pixel coordinates.

Turns real logged agent failures into trace-based behavioural test cases plus a one-command Python runner.

When the console is empty and the code looks fine but the app still doesn't work, this skill gathers evidence from the running page and hands you the file:line to open.

Installs a dev-only SDK into your running web app so the agent can read real DOM, network, console and framework state, drive one real user flow end to end, and return a pass/fail verdict with the file:line to fix.

Sweeps a running web app by clicking every reachable control and reports dead buttons, console errors, failed requests and API/UI contradictions — no codebase knowledge required.

A TDD skill that makes you declare the expected outcome before coding and run a real red-green loop against the live app, for behaviour unit tests cannot reach.

Installs a dev-only SDK into your running web app so the agent can read DOM, network, routing, console and store state, drive one real flow, and return a yes/no/unknown verdict with the file:line to fix.
