What it does

Secrets Scan is an agent skill from deonmenezes/mantishack. Run trufflehog via the mantistrufflehog MCP server and handle secret findings without ever exposing the raw secret

Its SKILL.md is about 350 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in DevOps & Cloud, covering Secrets management. It works with Model Context Protocol. The licence is Apache-2.0.

When your agent uses it

  • Tasks that involve Secrets management

Example prompts

  • “/secrets-scan”

What it can do on your machine

Read from SKILL.md and the folder at commit c3a2e68. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Secrets Scan loads about 347 tokens when it runs. Until then it costs about 32 tokens; SKILL.md has 180 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~32
When it runs · the whole SKILL.md, loaded when a task matches
~347

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Run trufflehog via the mantis_trufflehog MCP server and handle secret findings without ever exposing the raw secret

Use trufflehog_scan({ path, only_verified }) (mantis_trufflehog MCP server) for the Detect stage's secrets coverage.

  • The server already redacts every secret value before it reaches you (redacted_secret is a masked preview, never the full value). Never try to reconstruct, print, or echo the full secret elsewhere -- e.g. don't re-read the source line containing it and paste it into a report just because the tool redacted its own output.
  • verified: true means trufflehog live-checked the credential against its provider and it's currently active -- treat this as a near-confirmed finding with severity driven by what the credential can access. verified: false is a candidate (pattern-matched but not live-checked, could be a dead/rotated key or a false-positive-looking test fixture).
  • Remediation for any verified secret is always: rotate/revoke the credential at the provider, then remove it from source (and consider it compromised in git history even after removal -- flag that separately, since simply deleting the line does not purge history).
  • Set only_verified: true when you specifically want to cut noise from test fixtures and example keys; leave it off for full recall during an initial sweep.
