## 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 2026-08-20.

- **Supply Chain Security**: 98/100
  - No malware found by supply-chain analysis.
  - No known CVEs affecting this package version or its production dependencies.
  - No install/post-install scripts declared.
  - 30 of 95 dependencies flagged as unhealthy.
- **Provenance & Transparency**: 19/100
  - Repository check failed: the declared repository URL redirects; it must resolve directly.
  - Provenance check failed: no build-provenance attestation is published.
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 2 days ago).
  - Security-disclosure policy not yet verified: we couldn't inspect the source repository.
- **Schema Quality & AI Usability**: 80/100
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 701 tokens (~63/item across 11 items; 11 tools + 0 resources), lean.
  - 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.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

**Unverified: 1 category.** A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

### 2026-08-18 (score 39)

First indexed and scored.

## MCP tools (11)

### `triz_parameter` (~48 tokens)

Get a canonical TRIZ engineering parameter (1-39). Omit id to list all 39.

Input parameters:

- `id` (integer): Parameter number 1-39; omit to list all

### `triz_principle` (~61 tokens)

Get a canonical TRIZ inventive principle (1-40). Omit id to list all 40. Look up principle numbers instead of recalling them from memory.

Input parameters:

- `id` (integer): Principle number 1-40; omit to list all

### `triz_matrix` (~64 tokens)

Look up the canonical contradiction matrix for an improving and worsening engineering parameter. Blank and diagonal cells fail closed; never guess a recommendation.

Input parameters:

- `improving` (integer, required): Parameter to improve (1-39)
- `worsening` (integer, required): Parameter that worsens (1-39)

### `triz_matrix_multi` (~124 tokens)

Multi-parameter contradiction lookup: every (improving x worsening) matrix cell with the principles aggregated by how many cells recommend each (ties broken by mean position). Use when a conflict involves several parameters on either side; per-cell detail is returned so nothing is hidden. All-blank or diagonal-only results fail closed like triz_matrix.

Input parameters:

- `improving` (array, required): Parameters to improve (1-39), e.g. [9, 14]
- `worsening` (array, required): Parameters that worsen (1-39), e.g. [25, 33]

### `triz_resolve` (~63 tokens)

Look up a contradiction-matrix cell and expand its recommended principles and both engineering parameters. Fails closed on blank cells.

Input parameters:

- `improving` (integer, required): Parameter to improve (1-39)
- `worsening` (integer, required): Parameter that worsens (1-39)

### `triz_tool_catalog` (~42 tokens)

List the domain-neutral TRIZ tool catalog, optionally restricted to problem analysis, task modeling, or solution synthesis.

Input parameters:

- `stage` (string): Optional workflow stage

### `triz_effects` (~108 tokens)

Search the curated effects database by required function (e.g. 'convert temperature difference into voltage', 'store heat', 'sense strain') or list by category: physical, chemical, geometric. Effects are classical textbook phenomena; selecting and substantiating one remains a synthesis step, never a lookup verdict.

Input parameters:

- `category` (string): Restrict results to one category
- `query` (string): Function keywords to search for, e.g. 'store heat' or 'sense magnetic field'

### `triz_route` (~65 tokens)

Route a problem stage and optional observable signals to candidate TRIZ tools. Routing is deterministic and returns only tools registered for that stage.

Input parameters:

- `signals` (array): Problem signals such as bottleneck, stakeholder conflict, or harmful interaction
- `stage` (string, required): Current workflow stage

### `triz_evals` (~25 tokens)

Return the domain-neutral TRIZ lookup regressions and cross-domain reasoning cases.

### `triz_graph` (~51 tokens)

Optional project extension: analyse an OTSM Network of Problems (contradiction graph) and its verifier-backed purpose gates. Requires a project graph via TRIZ_GRAPH; not part of the neutral skill core.

### `triz_purpose` (~50 tokens)

Optional project extension: inspect the invariant and purpose gate for one contradiction node of the project graph.

Input parameters:

- `id` (string, required): Node id as used in the project graph, e.g. S1
