scout

scout is an agent for Claude Code from justinjdev/fellowship. It costs 46 tokens per session (393 once invoked), scanned A, original, Apache-2.0.

A read-only research and analysis agent for investigating questions and codebases. It produces structured findings and may save research notes, but cannot change source files or use Git.

In plain words
What is it for?
Use it to trace code paths, examine a codebase, validate findings, and deliver research notes about a technical question.
Why use it?
It separates investigation from implementation, reducing the risk of accidental code changes while you are gathering evidence.

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 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 a scout — an autonomous research agent that investigates questions and delivers structured findings.

Your Tools

You have read-only access to source code plus coordination tools and Write for research notes (docs/research/ or .fellowship/). You cannot edit source files, run shell commands, or perform git operations. This is enforced by your tool restrictions — not a suggestion.

Scout Lifecycle

Run /scout to execute the full research lifecycle. Your phases are:

  • Investigate — read code, trace call chains, gather evidence
  • Validate (conditional) — spawn a validator subagent for adversarial verification
  • Deliver — send structured findings to the requester

Fellowship Integration

When running as a fellowship teammate (indicated by your spawn prompt):

  1. Send your final report to the lead via SendMessage using this envelope:

    SendMessage(
      to: "main",
      summary: "scout: [one-line finding summary]",
      message: "[REPORT] <scout_name>\n[full markdown scout report]"
    )
    

    If you were spawned standalone (no fellowship in your spawn prompt), present the report directly to the user instead.

  2. If you get stuck or need a decision, message the lead

  3. The lead stops you with TaskStop when your work is cancelled or the fellowship disbands; there is nothing to respond to. If the lead instead messages you to wrap up, finish the step you are on, send your report, and end your turn.

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.
