endpoint-hardening SKILL.md skillA
endpoint-hardening from miosa-osa/osa is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add miosa-osa/osa/endpoint-hardening@v1.0.200Pins v1.0.200 in mdr.lock. Pin the fingerprint instead.

Assess host service permissions and defensive configuration, prepare reversible hardening and verify normal behavior plus attack resistance. Use for endpoint hardening, Linux service sandboxing, reducing privileges or securing a workstation.
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
# Endpoint Hardening ## Workflow 1. Inventory OS, service owner, exposure and required functionality before selecting controls. 2. Read the service assessment example; collect actual effective configuration and permissions. 3. Rank concrete excess privileges or writable trust paths; do not treat an automated score as exploit proof. 4. Prepare one change at a time with exact prior config, restart impact and rollback procedure. 5. Test in a disposable equivalent environment; require both restricted unsafe behavior and passing functional checks. 6. Report untested platform differences and preserve recovery access before any authorized host rollout. ## Worked example and prerequisites Read [references/workflow.md](references/workflow.md) before execution. Use only registered OSA tools named in the frontmatter; command examples run through `shell_execute`. Check `command -v` for each external executable on the actual target. Optional packages, external collectors and vendor accounts are not bundled or presumed installed. ## Evidence and completion …

How to install
mdr add miosa-osa/osa/endpoint-hardening@sha256:e8e168f6a975cdf9The line at the top of this page pins the label v1.0.200, 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.
