Docs

documentation-lookup helps agents answer library, framework, and API questions from current docs instead of memory. It is ideal for setup, configuration, reference, and code-example tasks when the latest syntax matters. Use the documentation-lookup skill for Skill Docs when a request depends on live documentation and version-accurate guidance.

codebase-onboarding analyzes an unfamiliar repo and generates a structured onboarding guide with an architecture map, key entry points, conventions, and a starter CLAUDE.md. Use it when joining a new project or setting up Claude Code for the first time in a repository.

code-tour creates reusable CodeTour .tour files with real file and line anchors. Use the code-tour skill for onboarding tours, architecture walkthroughs, PR tours, RCA paths, and code-tour for Technical Writing when you need a guided sequence instead of a flat summary.

The article-writing skill helps draft long-form content with strong structure, voice consistency, and evidence. Use it for articles, guides, tutorials, newsletters, and article-writing for Copywriting workflows where polished, publishable prose matters.

architecture-decision-records helps capture architectural decisions during Claude Code sessions as structured ADRs. It detects decision moments, records context, alternatives, and rationale, and keeps an ADR log for future maintainers. Useful for Technical Writing and engineering teams that need durable decision history.

brainstorming is a pre-implementation skill that explores context, asks clarifying questions one at a time, and requires design approval before any code. Includes an optional visual companion and strong support for Requirements Planning.

writing-skills is a Skill Authoring guide for creating, editing, and validating agent skills with a test-driven workflow. Learn the key files, prerequisites, and practical steps for pressure scenarios, baseline tests, and concise SKILL.md iteration.

writing-plans helps turn a spec or requirements doc into a detailed implementation plan with file-level guidance, task sequencing, testing steps, and a review prompt before coding starts.

using-superpowers is a session-start skill from obra/superpowers that forces skill lookup before any reply, helping agents discover and activate the right workflow first.

The internal-comms skill helps write internal company communications like 3P updates, newsletters, FAQs, status reports, and leadership updates using example-driven formats from the Anthropic skills repository.

doc-coauthoring is a structured workflow for drafting docs with AI through context gathering, iterative outlining, section-by-section writing, and reader testing for review-ready specs, RFCs, and proposals.

brand-guidelines gives agents Anthropic brand colors and typography for restyling docs, slides, HTML, and other text-led artifacts. Use it to apply consistent on-brand formatting, font hierarchy, and palette choices after content is drafted.

technical-writer is a lightweight documentation skill for creating clearer README files, API docs, setup guides, tutorials, onboarding docs, and release notes. It centers Technical Writing on user goals, quick starts, examples, and troubleshooting. The skill is delivered as a single SKILL.md file with no extra scripts or templates.

The editor skill provides a lightweight editing workflow for Proofreading, copy editing, line editing, and developmental editing. Install editor when you need clearer scope than a generic prompt, with simple setup and practical guidance from the repo’s single SKILL.md file.

write-a-skill skill guide for Skill Authoring: create a reusable agent skill with clear scope, concise instructions, and optional support files. Use it to write, refine, or build a new skill with better triggers, structure, and workflow than a generic prompt.

writing-shape is a conversational drafting skill for turning markdown raw material into a publishable article. It helps with opening selection, paragraph-by-paragraph development, and structure choices for Technical Writing, interview notes, transcript cleanup, and rough drafts. Use the writing-shape guide when you need a guided editorial process rather than a one-shot prompt.

writing-beats is a drafting workflow skill for turning raw markdown notes into an article one beat at a time. It helps writers, editors, and agents shape scattered notes into a readable narrative instead of a linear argument. Best for exploratory explainers, founder stories, case studies, and writing-beats for Blog Writing.

handoff turns the current conversation into a concise transfer document for the next agent. Use the handoff skill to capture status, decisions, blockers, and links to source artifacts instead of duplicating PRDs, plans, ADRs, issues, or diffs.

to-prd skill turns current conversation context and codebase understanding into a PRD, then publishes it to the project issue tracker. Use it when you already know the change and want a repo-aware PRD without an interview, especially for Skill Authoring workflows.

setup-matt-pocock-skills prepares a repo for Matt Pocock’s engineering skills by detecting the issue tracker, mapping triage labels, and locating domain docs before writing the `## Agent skills` block. Use this setup and discovery skill when onboarding a new repo, switching repos, or refreshing agent context for `AGENTS.md`, `CLAUDE.md`, and `docs/agents/`.

grill-with-docs is a planning-and-documentation skill that pressure-tests your plan against the repo’s existing domain model, sharpens terminology, and updates CONTEXT.md and ADRs as decisions crystallize. Use it for Technical Writing, product-minded engineering, and any workflow where repo-grounded language matters more than a prompt-only brainstorm.

protocol-reverse-engineering helps agents capture, inspect, and document unknown network protocols using Wireshark, tshark, tcpdump, and MITM workflows. Best for debugging custom client/server traffic, analyzing PCAPs, and mapping message structure, request flow, and field meanings.

python-testing-patterns is a practical skill for designing better Python tests with pytest, fixtures, mocking, async testing, parameterization, TDD structure, and CI-aware patterns.

The evaluation-methodology skill explains PluginEval scoring for Model Evaluation, including layers, rubrics, composite scoring, badge thresholds, and practical guidance for interpreting results and improving weak dimensions.
