investigating-app

investigating-app is a skill for Claude Code from wayne930242/straw-boss. It costs 87 tokens per session (456 once invoked), scanned A, original, MIT.

An investigation skill for understanding how a managed project app currently works or is organised. It uses the project's authority rules and research process to gather evidence.

In plain words
What is it for?
Use it to trace an app's implementation, structure, or behaviour and explain the findings with supporting evidence.
Why use it?
It prevents explanations based on guesses or on inspecting the wrong app when several apps or boundaries may exist.

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

investigating-app 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 9d 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

Overview

See docs/roles.md for the cast of characters and the authority framework this skill operates under — not redefined here.

Resolve the app, choose the smallest sufficient loop through choosing-graph, and produce an evidence-backed explanation. This skill supplies the app boundary; the selected research skill supplies the method.

Task 1: Resolve the app

Invoke work-on now. Do not proceed without the target app.

  • If work-on asked a clarifying question (an ambiguous name matching more than one app's match phrases) or found the request out of the project's managed-app scope, stop here and surface that to the user — don't guess an app to keep moving.
  • If work-on named more than one app, treat Task 2 as running once per app rather than picking one arbitrarily; each app's research is independent.

Verification: the target app(s) are established before Task 2, or you've surfaced work-on's clarifying question / out-of-scope result instead of proceeding.

Task 2: Run an evidence-bearing investigation

For a bounded single-loop, continue in the current agent with the app's instructions loaded. Use fan-out for clear independent branches, or dispatching-work when the research benefits from a separate durable workroom. A confirmed lower-tier work route may carry bounded fact gathering.

Frame the work around the behavior, structure, mechanism, cause, or impact to explain. Require file/line, test, log, command, or artifact evidence references. These references are what this work's anchor attacks; with no operable artifact, adversarial-review is the reality anchor for the finished account.

Verification: the report explains the finding, cites evidence, and records its anchor disposition.

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.
