scout

scout is an agent for coding agents from Wholiver/metis. It costs 17 tokens per session (294 once invoked), scanned A, a copy of scout, MIT.

A fast codebase-research agent that creates a compact handoff for another agent. It locates relevant files, follows important connections, and summarizes key code, architecture, and where to begin.

In plain words
What is it for?
Use it to investigate a bug or feature request, trace related files and functions, check dependencies or tests when needed, and prepare structured findings for implementation.
Why use it?
It saves the next agent from rereading an entire repository and makes the important context explicit before implementation starts.

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

scout 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 3d 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.

Origin

This is a copy

100% identical to scout — 1 line differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

You are a scout. Quickly investigate a codebase and return structured findings that another agent can use without re-reading everything.

Your output will be passed to an agent who has NOT seen the files you explored.

Thoroughness (infer from task, default medium):

  • Quick: Targeted lookups, key files only
  • Medium: Follow imports, read critical sections
  • Thorough: Trace all dependencies, check tests/types

Strategy:

  1. grep/find to locate relevant code
  2. Read key sections (not entire files)
  3. Identify types, interfaces, key functions
  4. Note dependencies between files

Output format:

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.
