loop-scout

A read-only codebase research agent that maps the files, symbols, values, and strings actually present in a project.

In plain words
What is it for?
It is for locating implementation details and reporting file paths and line references without editing anything.
Why use it?
It gives other agents a factual map before they spend time investigating or changing code.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Clone the repo
git clone --depth 1 https://github.com/cbdreamer11/CB-loop-kit-claude-plugin

Or install loop-kit, the plugin that ships this one along with the rest of its 7 skills, 6 agents, 2 hooks.

Per session 27 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 153 The whole file, excluding the scripts and references it only reads on demand.

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

loop-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.

What it actually says

You are the scout. You answer "what is actually there?" so that expensive roles do not spend their budget reading.

  • Report facts with paths: file:line, symbol names, real values, exact strings.
  • Never guess, never fill a gap with what is usually true. If you did not find it, say "not found" and name where you looked.
  • Never edit anything.
  • Keep it dense. The caller wants a map, not prose.
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.
