## 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**: 87/100
  - No malware found by supply-chain analysis.
  - Only part of the dependency tree could be resolved (95 of 99), so this covers what we could see, not the whole tree.
  - No install/post-install scripts declared.
  - Only part of the dependency tree could be resolved (95 of 99), so this covers what we could see, not the whole tree.
- **Provenance & Transparency**: 45/100
  - Source repository is publicly reachable at the declared URL.
  - Provenance check failed: no build-provenance attestation is published.
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 2 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 85/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 516 tokens (~73/item across 7 items; 4 tools + 3 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.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **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.

### 2026-07-31 (score 5)

First indexed and scored.

## MCP tools (4)

### `list_catalog` (~86 tokens)

List design principles & patterns

List the catalog of software-design concepts, optionally filtered by kind. Returns each concept's slug, name, category, and one-line summary.

Input parameters:

- `kind` (string): Filter by kind. "principle" = all principles; "solid"/"oop" narrow to the SOLID five / the four OOP pillars; "pattern" = all GoF patterns. Default "all".

Output parameters:

- `concepts` (array)
- `count` (number)

### `explain_concept` (~84 tokens)

Explain a principle or pattern

Return an authoritative explanation of one design principle or GoF pattern: intent, when to use it, trade-offs, participants, and related concepts. Accepts a slug, full name, or alias (e.g. "SRP", "factory").

Input parameters:

- `name` (string, required): Concept to explain, e.g. "open-closed", "SRP", "observer".

Output parameters:

- `category` (string)
- `found` (boolean)
- `markdown` (string)
- `name` (string)
- `slug` (string)
- `summary` (string)

### `scaffold_pattern` (~101 tokens)

Scaffold a GoF pattern

Generate a language-agnostic pseudo-code skeleton for a GoF pattern, showing its participants and how they collaborate. Optionally rename roles to your domain (e.g. Product -> Notification). Translate the result into your target language.

Input parameters:

- `names` (object): Optional role→name map, e.g. {"Product":"Notification","Creator":"Dispatcher"}.
- `pattern` (string, required): Pattern slug/name/alias, e.g. "observer", "factory-method".

Output parameters:

- `code` (string)
- `error` (string)
- `name` (string)
- `ok` (boolean)
- `roles` (array)
- `slug` (string)

### `check_smells` (~180 tokens)

Detect code smells (heuristic)

Scan a code snippet for heuristic design smells (long method, large class, long parameter list, deep nesting, duplication, large file). Each finding maps to the principle it hints at plus a suggested refactor. HEURISTICS ONLY — hints, never verdicts; a clean run does not certify good design.

Input parameters:

- `code` (string, required): The source snippet to analyze (one file's worth).
- `dupThreshold` (integer): Duplicate-line count (default 3).
- `largeClassMethods` (integer): Max methods per class (default 12).
- `longMethod` (integer): Max method lines (default 40).
- `maxDepth` (integer): Max nesting depth (default 4).
- `maxFileLines` (integer): Max file lines (default 400).
- `maxParams` (integer): Max parameters (default 4).

Output parameters:

- `count` (number)
- `smells` (array)
