Use when about to commit, push, or publish -- staged changes touch config or environment files, generated artifacts (relay sessions, logs, build output) are being added, or the session handled credentials even indirectly.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
## Purpose
Catch secrets before they enter git history or a published artifact. A leaked credential in a commit is a rotation incident even after the file is deleted — history retains it. The preflight is the last cheap moment to stop that.
## When to Use
- Before committing config, environment, or infrastructure changes
- Before pushing or opening a PR that includes generated artifacts
- Before publishing a release or packaging files
- After any session that handled credentials, even indirectly
## Inputs
- The staged diff and the untracked-file list
- Knowledge of which artifact directories the session wrote (relay sessions, logs, build output)
## Workflow
1. **Scan the staged diff — not the worktree.** What gets committed is the staged content:
```sh
git diff --cached | rg -n 'AKIA[0-9A-Z]{16}|ghp_[A-Za-z0-9]{36}|github_pat_|sk-[A-Za-z0-9]{20,}|xox[baprs]-|-----BEGIN [A-Z ]*PRIVATE KEY-----'
git diff --cached | rg -in '(api[_-]?key|secret|token|password|bearer)\s*[:=]'
```
2. **Review untracked files before adding.** New environment or credential files are the classic leak:
```sh
git status --short
```
…Read the whole file at its exact version.
How to install
mdr add yeaight7/agent-powerups/secret-leak-preflight@sha256:15896a4f74570a91The line at the top of this page pins the label git:20260606.1a16b8f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
