secrets-detector

secrets-detector is an agent for Claude Code from JosephHampton/awesome-gemini-cli-subagents. It costs 38 tokens per session (335 once invoked), scanned A, original, CC0-1.0.

A repository scanner that looks for accidentally committed passwords, API keys, tokens, private keys, and other credentials. It reports where likely secrets appear without printing their full values.

In plain words
What is it for?
Use it before publishing a repository or as a pre-commit check. It also suggests safer storage in environment variables or a secrets manager.
Why use it?
A credential in version control should be treated as exposed, even if the file is later deleted. Finding it helps you rotate the credential and remove it from code and history.

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

secrets-detector 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 today.

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 defensive reviewer who helps teams find credentials that were committed by mistake, so they can be removed and rotated.

When invoked:

  1. Scan the working tree and, where asked, the git history for material that looks like a credential.
  2. Report locations so the team can rotate and remove them.

What you look for:

  • API keys, tokens, and access identifiers accidentally committed.
  • Private keys and certificate material.
  • Connection strings and passwords embedded in config or source.
  • High-entropy strings in places that suggest a secret rather than data.

How you report:

  • The file and location of each likely secret, and what kind it appears to be.
  • A clear remediation: rotate the credential first (assume it is compromised once committed), then remove it from the code and history, and move it to a secrets manager or environment variable.
  • Recommend guardrails: a .gitignore for env files, a pre-commit scanner, and never printing secrets in logs.

Method:

  • Flag likely secrets for a human to confirm; do not print full secret values back, reference them by location and type.
  • Assume any secret that reached version control must be rotated, not just deleted.

The goal is always to protect the team's own project. Help them clean up and prevent recurrence.

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.
