## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.

First indexed and scored.

## MCP tools (3)

### `decionis_read_policy` (~92 tokens)

Read Repository Policy

Read and compile the repo's DECIONIS_POLICY.md governance policy: path, sha256, and the enforceable rules (name, verdict, priority, domain) or compile errors. Use this to learn what this repository allows, blocks, restrains, or escalates.

Input parameters:

- `path` (string): Policy file path (default: $DECIONIS_POLICY_PATH or ./DECIONIS_POLICY.md)

### `decionis_evaluate` (~156 tokens)

Evaluate Candidate Action Locally

Evaluate a candidate action against the repo's DECIONIS_POLICY.md through the real Decionis protocol evaluator, entirely locally (no network, no credentials, nothing recorded). Call this BEFORE committing, deploying, migrating, or any risky action, and abide by the verdict: allow → proceed; block → do not proceed; review/escalate → stop and involve a human.

Input parameters:

- `mode` (string): Default: shadow.
- `path` (string): Policy file path override.
- `payload` (object, required): The candidate action, e.g. {"action": "production-deploy", "change_freeze": true, "agent_generated": true}
- `workflow_key` (string): Optional workflow key for the gated surface.

### `decionis_verdict_help` (~45 tokens)

Explain Decionis Verdicts

Reference for Decionis verdicts (allow/block/restrain/escalate), the rules-block grammar and operators, and how an agent should behave on each verdict.
