doc-fetcher

doc-fetcher is a skill for Claude Code from Kit4Some/Oh-my-ClaudeClaw. It costs 0 tokens per session (2,413 once invoked), scanned A, original, MIT.

A documentation lookup skill for finding API and software-development-kit instructions. An API is a way for programs to communicate, while an SDK is a package of tools for building with a service or platform.

In plain words
What is it for?
Use it to find API references, SDK usage instructions, setup guidance, and examples for software libraries and services.
Why use it?
It reduces the need to guess how a library or service works and can retrieve relevant reference material when existing knowledge is incomplete.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

doc-fetcher scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Doc Fetcher — API & SDK Documentation Retrieval

Preamble

Before executing this skill:

  1. Load context from memory:

    memory_search(query: "{skill-relevant-query}", associative: true, limit: 5)
    memory_search(tag: "{skill-name}", limit: 3)
    

    Review returned memories for relevant past context, decisions, and patterns.

  2. Check OMC state for active work:

    state_get_status()
    

    If conflicting active tasks exist, warn the user before proceeding.

  3. Detect current branch (for git-related skills):

    git rev-parse --abbrev-ref HEAD 2>/dev/null || echo "not-a-git-repo"
    
  4. Check proactive mode:

    state_read("occ-proactive")
    

    If "false": do NOT proactively suggest other OpenClaw-CC skills during this session. Only run skills the user explicitly invokes.

  5. Log skill activation:

    memory_daily_log(type: "note", entry: "Skill activated: /{skill-name}")
    

Role

Fetch, structure, and persist API/SDK documentation. Uses Progressive Disclosure (summary first, details on request) to minimize context usage. Leverages Context Hub (chub) MCP for curated, versioned, LLM-optimized documentation with persistent annotations and quality feedback.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
