Inventories and hardens secrets stored on a Linux host — env and config files, systemd environments, cron and history leakage, SSH/TLS/signing key material, database credential chains, environment-variable boundaries, rotation posture, and backup hygiene — with read-only evidence commands and exact hardened end states.
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
> **REDACTION RULE — applies to every phase of this module and to the final report.** When any sweep surfaces a real secret value, the report prints exactly the first four characters followed by `…REDACTED` (shape: `sk-l…REDACTED`). Never transcribe full values into reports, tickets, chat, shell transcripts, or evidence archives. All examples in this document use deliberate fakes such as `EXAMPLE_NOT_A_REAL_TOKEN`. If a command would echo a secret (e.g., `systemctl show -p Environment`), capture only hit counts or redacted previews. ## Scope & Objectives Audit secrets and sensitive material stored **on one Linux host** (or rendered onto it from its config-as-code repo). Seven objectives, in execution order: 1. **Inventory sweep (read-only)** — locate every place credentials actually live in practice: `.env` files in app directories, config files (`application.yml`/`.properties`, `settings.py`, `config.json`, PHP `.env`), systemd `Environment=`/`EnvironmentFile=`, `/etc/<app-name>/*`, `docker-compose.yml` environment blocks plus sibling `.env`, crontab inline creds, shell rc exports, ops history files, backup scripts with embedded DB passwords. …

How to install
mdr add as-foss/aegis-skills/aegis-host-secrets@sha256:ea315ba8a21c762bThe line at the top of this page pins the label git:20260826.9702747, 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.
