Skill Authoring

rules-distill is a maintenance skill for Skill Authors and prompt library curators. It scans installed skills, distills repeated patterns into reusable rules, and helps you append, revise, or create rule files with less guesswork than a generic review prompt.

prompt-optimizer is a prompt-optimizer skill that analyzes rough prompts, finds missing context, and rewrites them into clearer, ready-to-paste prompts. It is best for prompt-optimizer guide work, prompt review, and prompt-optimizer for Prompt Writing, especially when you need better structure for Claude Code or ECC workflows. It does not execute the underlying task.

hookify-rules helps you create Hookify rule files with YAML frontmatter for .claude/hookify.{rule-name}.local.md. Use it to define the right event, pattern, and action for warnings or blocks, and to turn a rough policy into a reliable hookify-rules guide for Skill Authoring.

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.

continuous-learning-v2 turns Claude Code sessions into project-scoped learning with hooks, observer agents, confidence scoring, and promotion of repeated patterns into skills, commands, or agents.

continuous-learning automatically extracts reusable patterns from Claude Code sessions and saves them as learned skills. It uses a Stop-hook flow, supports configurable thresholds in config.json, and is best for skill authors, repo maintainers, and power users who want a practical continuous-learning guide for session-end capture.

agent-sort is a repo-aware skill for building an evidence-backed ECC install plan. It helps sort skills, commands, rules, hooks, and extras into DAILY vs LIBRARY buckets so you install only what the project actually uses. Use the agent-sort skill for install decisions, agent-sort usage, and a practical agent-sort guide for Skill Authoring workflows.

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.

skill-creator is a Skill Authoring meta-skill for drafting new skills, revising existing SKILL.md files, running evals, comparing variants, and improving trigger descriptions with repository scripts and review tools.

mcp-builder is a practical guide for planning, building, and evaluating MCP servers for external APIs and services. It helps developers choose tool scope, naming, transport, Python or Node implementation patterns, and evaluation workflows so agents can use the server reliably.

document-release is a post-ship documentation update skill that reads project docs, cross-references the shipped diff, and updates README, ARCHITECTURE, CONTRIBUTING, CLAUDE.md, CHANGELOG, and VERSION so docs match what actually shipped. Use the document-release skill for technical writing when code is already merged and you need a reliable document-release guide.

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.

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.

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.

ubiquitous-language is a DDD-style skill that extracts a shared glossary from conversations, flags ambiguous terms and synonyms, and writes UBIQUITOUS_LANGUAGE.md. Use it to define domain terms, align teams, and improve ubiquitous-language for Technical Writing.

using-agent-skills is the meta-skill for routing work to the right Agent Skills workflow. Use it at session start or when task phase changes to choose the right downstream skill for Skill Discovery, planning, implementation, testing, debugging, review, or release.

spec-driven-development is a workflow skill for writing specs before code, then moving through planning, tasks, and implementation with human review at each phase.

documentation-and-adrs helps agents write decision-focused technical documentation and ADRs. Use it to capture context, constraints, tradeoffs, rejected options, and consequences for architecture, APIs, infrastructure, auth, and feature changes. It is ideal when you need durable rationale for future engineers and agents, not just a polished summary.

The context-engineering skill helps you structure project context so agents follow conventions, reduce hallucinations, and stay focused. Use it when starting a session, switching tasks, or building a context-engineering guide for a codebase.

write-a-skill helps Skill Authoring teams create new agent skills with a clear SKILL.md, smart file layout, and better trigger wording for reliable agent routing.

interview-script helps you create structured customer interview guides with warm-up, core exploration, and wrap-up sections. It follows The Mom Test and JTBD-style probing to keep questions neutral, avoid pitching, and focus on past behavior for discovery, product, and UX research interviews.

huggingface-paper-publisher helps publish and manage research papers on the Hugging Face Hub. Use it to index arXiv papers, link papers to models or datasets, verify authorship, and create markdown research articles with templates for technical writing.

neat-freak is a knowledge cleanup skill for end-of-session handoffs. It reconciles project docs, agent memory, and code drift so CLAUDE.md, AGENTS.md, and docs/ stay accurate. Useful for technical writing, developers, and agent operators who need a cleaner, more reliable project knowledge base.
