## 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)

Scored 2026-08-03.

- **Supply Chain Security**: 50/100
  - Malware scan not yet available for this package.
  - No known CVEs affecting this package version or its production dependencies.
  - Runs setuptools.build_meta at install time, a recognised native-build step with no shell scripting around it.
  - No production dependencies, so there is no dependency health to assess.
- **Provenance & Transparency**: 32/100
  - Source repository is publicly reachable at the declared URL.
  - Provenance check failed: no build-provenance attestation is published.
  - License check failed: no license is declared.
  - Actively maintained (last published 47 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 0/100
  - Schema quality not yet verified: our sandbox run of this package did not complete, so we have no schema to assess.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: our sandbox run of this package did not complete, so we have no schema to compare.
- **Tool Coverage**: 0/100
  - Tool coverage not yet verified: our sandbox run of this package did not complete, so we have no tool definitions to assess.
- **Capabilities**: 0/100
  - Protocol version not yet verified: our sandbox run of this package did not complete, so we never saw its MCP handshake.

**Unverified: 4 categories.** Categories scored 0 because our sandbox run of this package has not given us the schema these checks need to read. That is a gap on our side rather than a finding about the package, and we only credit what we can confirm, so the score stands at 0 until the capture succeeds. We are working through the fleet, so this normally clears without any action from you.

## MCP tools (3)

### `t1_protocol` (~148 tokens)

Translates ambiguous questions into T1 structured prompts. Output: L1 facts / L2 assumptions / L3 hypotheses / L4 unknowns / core question / output requirements. v2.5+: L3 evidence status, core link exemption.

Input parameters:

- `locale` (string): Output language: 'en' (default) or 'zh'
- `question` (string, required): The original question to translate
- `weight_hint` (string): Optional evaluation weight hint. English: fact-first, efficiency-first, cost-first, robustness-first, general-first. Chinese: 事实优先, 效率优先, 成本优先, 鲁棒性优先, 通用优先.

### `t2_protocol` (~105 tokens)

Confidence evaluation for AI answers. Output: qualitative confidence (high/medium-high/medium/medium-low/low) + adoption recommendations. Run checksum before T2 when format integrity matters.

Input parameters:

- `answer` (string, required): The AI answer to evaluate
- `locale` (string): Output language: 'en' (default) or 'zh'
- `weight_hint` (string): Optional evaluation weight hint (default: factual accuracy > efficiency). Same values as t1_protocol weight_hint.

### `checksum` (~73 tokens)

Deterministic structural pre-validation (semantic ECC Pre-T2 Checksum)
Input: AI answer text
Output: structural integrity assessment (pass/fail) + diagnostics
Zero LLM dependency - pure regex/string ops. Run before T2 to filter corrupted output.

Input parameters:

- `text` (string, required): The AI answer text to validate
