Use when classifying any operation before executing it, or deciding whether user approval is required.
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
# Security Tiers ## COMMAND_SET boundary Classification applies to each exact atomic command. After read-only investigation, one or more predictable T3 commands may be requested plan-first with `gaia approvals request-set` -- a single predictable T3 command uses the same verb proactively, not only after the pre-execution policy gate returns `[T3_BLOCKED]`. Never discover a set by attempting a compound shell command. `subagent-request-approval` owns request construction and grouping; this skill owns the classification and no-elusion decision that routes work there. security-tiers classifies every operation into four tiers so an agent knows whether it can run freely or must request the user's consent. ## The four tiers | Tier | What it is | Approval? | Example verbs | |------|------------|:---:|---------------| | **T0** | Read-only; observes state, changes nothing | No | get, list, describe, show, logs, status | | **T1** | Local validation; no remote calls, no state | No | validate, lint, fmt, check | | **T2** | Simulation / dry-run; may read remote, never writes | No | plan, diff, --dry-run, template | …

How to install
mdr add metraton/gaia/security-tiers@sha256:3b4411ffac716fd2The line at the top of this page pins the label git:20261015.05c65fd, 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.
