Classify a proposed action's risk tier (T0–T4), apply the gate policy, and (if required) summarize the proposal into a human-reviewable approval request. Use whenever an agent is about to perform an action that touches anything outside its own scratch state.
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
# Approval Gate Skill The approval gate is the structural mechanism by which Roster **decouples decision from enactment**. Every agent calls this skill before any action that touches the environment. ## When to use - A sub-agent is about to invoke a tool that mutates state (filesystem, repo, DB, network, infra). - The planner is about to dispatch a plan to the execution plane (the plan itself goes through a gate the first time it's ratified). - Any agent encounters an ambiguous or unexpectedly-large action (escalate up tiers when unsure). ## Procedure ### Step 1 — Build an `ActionProposal` Populate every required field of [`shared/schemas/action-proposal.schema.json`](../schemas/action-proposal.schema.json): - `action.kind`, `action.summary`, `action.target`, `action.command` (if applicable) - `rationale` — reference the ratified plan + this task's `successCriteria` - `reversibilityPlan` — "git revert <sha>", "drop snapshot <id>", or literally `"IRREVERSIBLE"` - `recoverabilityState` — `backupVerified: true` is **mandatory** for T4 - `diffPreview` — required for T3+, strongly recommended for T2 - `blastRadius` — scope + a count or description of affected entities …

How to install
mdr add zhiming-dev/roster/approval-gate@sha256:15fd157ae1bfcaf1The line at the top of this page pins the label git:20260607.cffeb43, 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.
