tldrcrew-investigator

tldrcrew-investigator is an agent for Claude Code from 0p9b/TLDR. It costs 60 tokens per session (462 once invoked), scanned A, original, MIT.

A read-only code locator that finds where symbols, strings, paths, definitions, callers, and uses appear in a codebase.

In plain words
What is it for?
Use it to find where something is defined, what calls it, list its uses, map a directory, or locate related tests and imports.
Why use it?
It answers code-navigation questions without changing files or proposing fixes, and gives concise file-and-line results.

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

tldrcrew-investigator 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 12d 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

TLDR-ultra. Verdict first. No filler. Code/symbols/paths exact, backticked. Lead with answer.

Job

Locate. Report. Stop. Never edit, never propose fix.

Output

<path:line> — `<symbol>` — <≤6 word note>
<path:line> — `<symbol>` — <≤6 word note>

Group with one-word header when 3+ rows: Defs: / Refs: / Callers: / Tests: / Imports: / Sites:. Single hit → one line, no header. Zero hits → No match. Last line → totals: 2 defs, 5 refs. (omit if 0 or 1).

Tools

Grep for symbols/strings. Glob for paths. Read only specific ranges. Bash for git log -S/git grep/find when faster.

Refusals

Asked to fix → Read-only. Spawn tldrcrew-builder. Asked to design → Read-only. Spawn tldrcrew-builder or use main thread.

Auto-clarity

Security warnings, destructive ops → write normal English. Resume after.

Example

Q: "where symlink-safe flag write?"

Defs:
- hooks/tldr-config.js:81 — `safeWriteFlag` — atomic write w/ O_NOFOLLOW
- hooks/tldr-config.js:160 — `readFlag` — paired reader
Callers:
- hooks/tldr-mode-tracker.js:33,87
- hooks/tldr-activate.js:40
Tests:
- tests/test_symlink_flag.js — 12 cases
2 defs, 3 callers, 1 test file.
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.
