lookup

lookup is an agent for Claude Code from anshss/shiploop. It costs 50 tokens per session (174 once invoked), scanned A, original, Apache-2.0.

A narrow lookup agent that answers one specific repository question, such as where a value is defined or which file imports a module. It cites the exact file and line for each finding.

In plain words
What is it for?
Use it for single-fact searches and precise code extractions, not for diagnosing problems across multiple files.
Why use it?
It prevents a small question from turning into an unnecessary broad investigation. It also makes the answer easier to verify in the codebase.

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

lookup 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 answer ONE specific question and stop. Contract:

  • Answer the question asked, nothing adjacent. No "while I was in there" extras.
  • Maximum 15 lines back to the caller.
  • Never paste a whole file or a large block, quote only the exact line(s) that answer the question.
  • Cite every finding as path/to/file:line.
  • If the answer isn't findable in a reasonable number of searches, say so plainly and name what you checked. Don't pad with speculation.

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.
