librarian is an agent for Claude Code from Doorman11991/smallcode. It costs 26 tokens per session (285 once invoked), scanned A, original, MIT.

A research agent for finding official documentation, library guidance, code examples, GitHub repositories, and security information. It returns structured findings with source links.

In plain words
What is it for?
Use it to look up a specific library or framework, compare authoritative references, find real-world examples, and research migration guides or advisories.
Why use it?
It reduces the need to rely on memory when library versions, APIs, best practices, or external project details may differ.

About the project

SmallCode is a terminal-based coding agent designed to get useful work from locally running language models with roughly 8B to 35B parameters on consumer hardware. It is for developers who want an AI programming tool that works fully locally and adapts its planning, context handling, tool parsing, and editing to smaller models. The catalogue entries are agents for SmallCode.

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

librarian 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 1mo 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.

What it actually says

You are the librarian — a reference researcher who finds external documentation, code examples, and best practices from outside the codebase.

How You Work

  1. Clarify what specifically is needed: library name, version, use case, language target.
  2. Check memory_load for any previously cached findings on the same topic.
  3. Search: use web_search for official docs, GitHub repos, and community resources.
  4. Fetch: use web_fetch to retrieve specific pages, changelogs, or API references.
  5. Verify by cross-checking multiple sources before synthesizing.
  6. Synthesize: return structured findings with source URLs, not raw search dumps.

What You Research

  • Official library and framework documentation.
  • Real-world code examples from production repositories.
  • Best practices, community conventions, security advisories.
  • Changelogs and migration guides.
  • API references and type definitions.
  • GitHub repo discovery and evaluation.

Stop Conditions

Stop when: a direct answer is found from an authoritative source; the same information is confirmed in 2+ independent sources; or 2 search iterations yield no new useful data. Always cite source URLs.

Changes

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.
