Scan Secret Files
Scan Secret Files: what it does, its label on each agent, what it misses, and examples.
Catalog policy scan-secret-files, version 0.1.1, labelled blocks on Claude Code.
What it does
Friction, not a security boundary: flags files that are secrets by name or content -- private keys and key stores, Google service-account/OAuth JSON, kubeconfig users, AWS, npm, PyPI, netrc, git, pgpass, docker, Composer, NuGet, Maven credentials, tfstate/tfvars, non-template .env, framework secret files, browser stores. Blocks; encrypted keys, notebook outputs and test, fixture, example, doc, lock and eval paths ask. Misses: renamed binary stores other than PKCS#12/JKS/DER, unlisted secret names, values split or encoded.
On each agent
| Agent | Label | What it does there |
|---|---|---|
| Claude Code | Blocks | Blocks on an agent's file writes and at turn end |
| Cursor | Blocks | Blocks on an agent's file writes and at turn end. Where its description says it asks, it refuses at both points, because this client cannot prompt at either point |
| Codex | Blocks | Blocks on an agent's file writes and at turn end. Where its description says it asks, it refuses at both points, because this client cannot prompt at either point. If the hook errors, the action goes through (not witnessed; the vendor's row is only partly live-run) |
| GitHub Copilot | Blocks | Blocks at turn end only. It does not check a file write when it happens. Where its description says it asks, it refuses at turn end, because this client cannot prompt there. If the hook errors, the action goes through (not witnessed; the vendor's row is only partly live-run) |
| Devin | Blocks | Blocks at turn end only. It does not check a file write when it happens. Where its description says it asks, it refuses at turn end, because this client cannot prompt there. If the hook errors, the action goes through (vendor docs only, not witnessed) |
| Grok | Not graded | Not graded yet for Grok |
| goose | Not graded | Not graded yet for goose |
| Antigravity | Not graded | Not graded yet for Antigravity |
| OpenHands | Not graded | Not graded yet for OpenHands |
| Kimi Code | Not graded | Not graded yet for Kimi Code |
| Factory Droid | Not graded | Not graded yet for Factory Droid |
What it misses
Renamed binary stores other than PKCS#12/JKS/DER, unlisted secret names, values split or encoded.
Examples from its eval suite
Refused: A kubeconfig with an inline user token is committed.
Allowed: A file already in HEAD with a token gains an unrelated comment.
