opensrc
Fetch dependency source code to give AI agents deeper implementation context. Use when the agent needs to understand how a library works internally, read source code for a package, fetch implementation details for a dependency, or explore how an npm/PyPI/crates.io package is built. Triggers include "fetch source for", "read the source of", "how does X work internally", "get the implementation of", "opensrc path", or any task requiring access to dependency source code beyond types and docs.
What this skill does
# Source Code Fetching with opensrc Fetches dependency source code so agents can read implementations, not just types. Clones repositories at the correct version tag and caches them globally at `~/.opensrc/`. ## Core Pattern ```bash rg "parse" $(opensrc path zod) cat $(opensrc path zod)/src/types.ts find $(opensrc path zod) -name "*.test.ts" ``` `opensrc path <pkg>` prints the absolute path to cached source. If not cached, it fetches automatically. Progress goes to stderr, path to stdout, so `$(opensrc path ...)` works in subshells. ## Fetching Source Code ```bash opensrc path zod opensrc path pypi:requests opensrc path crates:serde opensrc path facebook/react # Multiple packages at once opensrc path zod react next opensrc path pypi:requests pypi:flask opensrc path crates:serde crates:tokio # Specific versions opensrc path [email protected] opensrc path pypi:[email protected] opensrc path owner/[email protected] opensrc path owner/repo#main ``` ### Version Resolution For npm packages, opensrc auto-detects the installed version from lockfiles (`package-lock.json`, `pnpm-lock.yaml`, `yarn.lock`). Use `--cwd` to resolve from a different project: ```bash opensrc path zod --cwd /path/to/project ``` For PyPI and crates.io, explicit versions or latest are used. For repos, use `@ref` or `#ref` to pin a branch, tag, or commit. ## Managing the Cache Source is cached globally at `~/.opensrc/` (override with `OPENSRC_HOME`). ```bash opensrc list # show all cached sources opensrc list --json # JSON output opensrc remove zod # remove a package opensrc remove facebook/react # remove a repo opensrc clean # remove everything opensrc clean --npm # only npm packages opensrc clean --pypi # only PyPI packages opensrc clean --crates # only crates.io packages opensrc clean --packages # all packages, keep repos opensrc clean --repos # all repos, keep packages ``` ## When to Fetch Source Fetch source when you need to: - Understand internal behavior that types don't reveal - Debug unexpected library behavior - Learn patterns from well-known implementations - Verify how a function handles edge cases Don't fetch source for simple API usage questions that docs or types can answer.

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.
