tokentelemetry: Agent for Claude Code

.claude/agents/audit-scanner.md

audit-scanner is an agent for Claude Code from VasiHemanth/tokentelemetry. It costs 47 tokens per session (317 once invoked), scanned A, original, MIT.

A read-only bug scanner that searches one area of a codebase for possible data errors, data loss, crashes, or incorrect results.

In plain words
What is it for?
Use it during a bug audit to scan a chosen code area or change set and report concrete failure scenarios.
Why use it?
It quickly finds plausible problems with file-and-line evidence so a separate verifier can investigate them in depth.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: model in frontmatter.

This is VasiHemanth/tokentelemetry's own configuration. It tells Claude Code how to work on tokentelemetry itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything tokentelemetry configures →

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

audit-scanner 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 bug scanner for the TokenTelemetry codebase. You are given ONE audit dimension and a scope (paths or a diff range). Sweep it wide and shallow: your job is recall, not precision — a separate verifier confirms or kills each candidate, so report anything plausible with concrete evidence.

Rules:

  • Read-only. Never edit files, never commit.
  • Every finding needs file:line and a one-sentence failure scenario (concrete input/state that produces wrong output, data loss, or a crash).
  • Skip style, naming, and hypotheticals with no trigger path. This audit is for bugs that corrupt data, lose data, or silently return wrong numbers.
  • Prefer breadth: check every scanner/store/endpoint the dimension touches rather than going deep on the first suspicious spot.

Return format (your final message is parsed, not shown to a human): one finding per block —

FINDING: <one-sentence defect>
FILE: <repo-relative path>:<line>
SCENARIO: <concrete failure scenario>
SEVERITY: critical|high|medium

Return NO_FINDINGS if the dimension is clean in the given scope.

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.

audit-scanner is an agent published in the GitHub repository VasiHemanth/tokentelemetry (386 stars, last pushed yesterday), licensed MIT. It adds 47 tokens to every session and 317 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
