context7-cli
Use the ctx7 CLI to fetch library documentation, manage AI coding skills, and configure Context7 MCP. Activate when the user mentions "ctx7" or "context7", needs current docs for any library, wants to install/search/generate skills, or needs to set up Context7 for their AI coding agent.
What this skill does
# ctx7 CLI The Context7 CLI does three things: fetches up-to-date library documentation, manages AI coding skills, and sets up Context7 MCP for your editor. Make sure the CLI is up to date before running commands: ```bash npm install -g ctx7@latest ``` Or run directly without installing: ```bash npx ctx7@latest <command> ``` ## What this skill covers - **[Documentation](references/docs.md)** — Fetch current docs for any library. Use when writing code, verifying API signatures, or when training data may be outdated. - **[Skills management](references/skills.md)** — Install, search, suggest, list, remove, and generate AI coding skills. - **[Setup](references/setup.md)** — Configure Context7 MCP for Claude Code / Cursor / OpenCode. ## Quick Reference ```bash # Documentation ctx7 library <name> <query> # Step 1: resolve library ID ctx7 docs <libraryId> <query> # Step 2: fetch docs # Skills ctx7 skills install /owner/repo # Install from a repo (interactive) ctx7 skills install /owner/repo name # Install a specific skill ctx7 skills search <keywords> # Search the registry ctx7 skills suggest # Auto-suggest based on project deps ctx7 skills list # List installed skills ctx7 skills remove <name> # Uninstall a skill ctx7 skills generate # Generate a custom skill with AI (requires login) # Setup ctx7 setup # Configure Context7 MCP (interactive) ctx7 login # Log in for higher rate limits + skill generation ctx7 whoami # Check current login status ``` ## Authentication ```bash ctx7 login # Opens browser for OAuth ctx7 login --no-browser # Prints URL instead of opening browser ctx7 logout # Clear stored tokens ctx7 whoami # Show current login status (name + email) ``` Most commands work without login. Exceptions: `skills generate` always requires it; `ctx7 setup` requires it unless `--api-key` or `--oauth` is passed. Login also unlocks higher rate limits on docs commands. Set an API key via environment variable to skip interactive login entirely: ```bash export CONTEXT7_API_KEY=your_key ``` ## Common Mistakes - Library IDs require a `/` prefix — `/facebook/react` not `facebook/react` - Always run `ctx7 library` first — `ctx7 docs react "hooks"` will fail without a valid ID - Repository format for skills is `/owner/repo` — e.g., `ctx7 skills install /anthropics/skills` - `skills generate` requires login — run `ctx7 login` first

skill-development
IncludedComprehensive meta-skill for creating, managing, validating, auditing, and distributing Claude Code skills and slash commands (unified in v2.1.3+). Provides skill templates, creation workflows, validation patterns, audit checklists, naming conventions, YAML frontmatter guidance, progressive disclosure examples, and best practices lookup. Use when creating new skills, validating existing skills, auditing skill quality, understanding skill architecture, needing skill templates, learning about YAML frontmatter requirements, progressive disclosure patterns, tool restrictions (allowed-tools), skill composition, skill naming conventions, troubleshooting skill activation issues, creating custom slash commands, configuring command frontmatter, using command arguments ($ARGUMENTS, $1, $2), bash execution in commands, file references in commands, command namespacing, plugin commands, MCP slash commands, Skill tool configuration, or deciding between skills vs slash commands. Delegates to docs-management skill for official documentation.
reprompter
IncludedTransform messy prompts into well-structured, effective prompts — single or multi-agent. Use when: "reprompt", "reprompt this", "clean up this prompt", "structure my prompt", rough text needing XML tags and best practices, "reprompter teams", "repromptception", "run with quality", "smart run", "smart agents", multi-agent tasks, audits, parallel work, anything going to agent teams. Don't use when: simple Q&A, pure chat, immediate execution-only tasks. See "Don't Use When" section for details. Outputs: Structured XML/Markdown prompt, quality score (before/after), optional team brief + per-agent sub-prompts, agent team output files. Success criteria: Single mode quality score ≥ 7/10; Repromptception per-agent prompt quality score 8+/10; all required sections present, actionable and specific.
adaptive-compaction
IncludedAdaptive add-on policy and recovery layer that decides WHEN to compact, prune, snapshot, or fork -- replacing fixed-percent auto-compaction across Claude Code, Codex, and MCP-capable hosts. Trigger on auto-compact timing or damage: "when should I compact", "is it safe to compact now or start a fresh session", "auto-compact fires too early/mid-task", "switching to an unrelated task but the window still has space", "context rot", "answers get worse the longer the session runs", "the agent forgot the plan or my decisions after it summarized", "add a layer on top that manages context without changing the agent", raising autoCompactWindow to give the policy room, or installing/tuning a cross-tool compaction policy or PreCompact hook -- even when "compaction" is never said but the problem is context-window pressure or post-summarization memory loss. Do NOT use to summarize a conversation, build RAG, write a summarization prompt (decides WHEN not HOW), or answer max-context-length trivia.
agent-skill-creator
IncludedCreate cross-platform agent skills from workflow descriptions. Activates when users ask to create an agent, automate a repetitive workflow, create a custom skill, or need advanced agent creation. Triggers on phrases like create agent for, automate workflow, create skill for, every day I have to, daily I need to, turn process into agent, need to automate, create a cross-platform skill, validate this skill, export this skill, migrate this skill. Supports single skills, multi-agent suites, transcript processing, template-based creation, interactive configuration, cross-platform export, and spec validation.
llm-wiki
IncludedUse when building or maintaining a persistent personal knowledge base (second brain) in Obsidian where an LLM incrementally ingests sources, updates entity/concept pages, maintains cross-references, and keeps a synthesis current. Triggers include "second brain", "Obsidian wiki", "personal knowledge management", "ingest this paper/article/book", "build a research wiki", "compound knowledge", "Memex", or whenever the user wants knowledge to accumulate across sessions instead of being re-derived by RAG on every query.
skill-master
IncludedAgent Skills authoring, evaluation, and optimization. Create, edit, validate, benchmark, and improve skills following the agentskills.io specification. Use when designing SKILL.md files, structuring skill folders (references, scripts, assets), ingesting external documentation into skills, running trigger evals, benchmarking skill quality, optimizing descriptions, or performing blind A/B comparisons. Keywords: agentskills.io, SKILL.md, skill authoring, eval, benchmark, trigger optimization.
