## 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)

  - Malware scan not yet available for this package.
  - CVE data not yet available for this package.
  - 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**: 39/100

  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 73/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 460 tokens (~153/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 23/100
  - Stability observed for 7 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **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

## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-08-03 (score 45, +1)

No change was recorded against any check on this day. Stability & Change Management went from 20 to 23. That category is still filling its 30-day observation window: 6 days of observed history at the previous scan, 7 at this one. The score rises as the window fills, whether or not the server changes.

### `check_ai_slop` (~170 tokens)

Check text for AI-writing style tells

Score any prose 0-100 on how human it reads (100 = reads human) by counting six families of style tells: LLM word/phrase density, em-dash density, formulaic structures, sentence-length uniformity, lack of specifics, and over-perfect bullet lists. Returns the score, a verdict, per-dimension sub-scores with the raw counts that produced them, and up to 6 concrete fixes. Fully deterministic and local: no LLM call, no network, same input always gives the same number. This measures STYLE, not authorship — it is a tells counter, not an AI detector.

Input parameters:

- `text` (string, required): The prose to score. At least ~200 characters gives a reliable read; shorter text still scores but the sentence-rhythm dimension is skipped.

### `grade_landing_copy` (~204 tokens)

Grade landing-page hero copy

Score a landing-page hero (headline + sub-headline + call-to-action button) 0-100 across five weighted dimensions: Anti-hype (25), Specificity (25), Clarity (25), Headline shape (13), CTA (12). Returns the score, a verdict, per-dimension sub-scores with raw counts, short flags, and up to 6 targeted rewrites. Deterministic, no LLM, no network. This is the same engine used to score the public 239-page dataset exposed by get_slop_stats, so scores are directly comparable to real landing pages.

Input parameters:

- `cta` (string): The call-to-action button label, e.g. "Start your first invoice". Optional, but an empty CTA scores 0 on that dimension.
- `headline` (string, required): The hero headline (h1).
- `subhead` (string): The sub-headline / first sub-line under the h1. Optional.

### `get_slop_stats` (~86 tokens)

Benchmark stats from 239 real landing pages

Return the reference distribution for grade_landing_copy: 239 real landing pages (min 41, median 79, mean 80.1, 19 perfect scores), how often each tell fires across them, the 10 lowest-scoring domains, and the score distribution. Use it to tell a user whether their score is actually good. Static local data, no network.
