scan-secrets

100 / 100 · Low risk

Fine to try.

By open-coder-ai/chock (GitHub) · coding · 10 stars · scanned at commit 9fe0a59

Blocks known credential patterns -- vendor key prefixes, private-key blocks, and key/token/password assignments -- at two enforcement points: at commit (the git hook, over staged changes) and at agent tool-use (the mcp-gateway / agent write guard, over a tool call's arguments), so a secret is caught as the agent writes it, before it ever reaches a commit. Matched by pattern, not by entropy analysis. Best-effort guard; not a replacement for a dedicated secret scanner.

Works with any agent that supports SKILL.md skills.

What this skill can do

We found nothing in the files we read that matches our rules. That does not prove the skill is safe: see the limits of static scanning.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'scan-secrets' ] || [ -L ~/.agents/skills/'scan-secrets' ]; then echo 'A skill folder named scan-secrets already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/open-coder-ai/chock' "$d" && git -C "$d" checkout --quiet '9fe0a59174384230f02faeecbe4a837ff3e96b9a' -- '.agents/policies/scan-secrets/skills/scan-secrets' && mkdir -p ~/.agents/skills && cp -R "$d"/'.agents/policies/scan-secrets/skills/scan-secrets' ~/.agents/skills/'scan-secrets' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'scan-secrets' ~/.claude/skills/'scan-secrets' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
