- hygiene: 100
- liveness: 100
- freshness: 100

## Quality 80/100 (good)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-11-25; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 100 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- pass `tools.annotations`: 7 of 7 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 883 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 50 (weight 15)

- pass `stability.changes`: 3 tool changes in 30 days
- fail `stability.rug_pull`: 1 tools kept their name but changed most of their description in 30 days; review before trusting them

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 7, about 883 tokens to load them all
- tool set hash: e98fffd4e20b9c8825b0a86a33108205
- tools last changed: 2026-10-13T02:22:20.269Z
- badge: [![protogrid quality](https://protogrid.dev/badge/com.sloppatterns/slop-patterns.svg)](https://protogrid.dev/servers/com.sloppatterns/slop-patterns)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-10-13 `report_pattern` changed (description)
  - before: Report an AI design anti-pattern that is NOT yet in the library. Use this when you notice the same design failure repeatedly and a search of the library turns up nothing. Reports are reviewed by a human before anything is published, and published entries credit the reporter.
  - after: Report an AI design anti-pattern that is NOT yet in the library, for a design failure seen repeatedly that a search of the library does not find. Reports are reviewed by a human before anything is published, and published entries credit the reporter.
- 2026-10-13 `search_patterns` changed (description) **meaning changed**
  - before: Plain-language search across the library. "dark mode with no light option" returns A7 Permanent Midnight.
  - after: Plain-language search across the library. "gradient headline" returns A10 Gradient Text Headline.
- 2026-10-13 `check_design` changed (description)
  - before: Check a snippet of CSS, HTML or JSX against the Slop Patterns library and return every AI design anti-pattern it matches, with the fix for each. Covers the 104 patterns that have a mechanical tell. Call this on generated UI code before presenting it to the user.
  - after: Check a snippet of CSS, HTML or JSX against the Slop Patterns library and return every AI design anti-pattern it matches, with the fix for each. Covers the 101 documented patterns that have a mechanical tell. Useful for reviewing generated UI code.

## Tools (7)

- `changelog`: The library version, what each release added or changed, and how patterns are versioned. Use it to cite a specific version of Slop Patterns.
- `check_design`: Check a snippet of CSS, HTML or JSX against the Slop Patterns library and return every AI design anti-pattern it matches, with the fix for each. Covers the 101 documented patterns that have a mechanical tell. Useful for reviewing generated UI code.
- `get_pattern`: Get one full pattern entry by id or code (e.g. "a1" or "the-unchosen-gradient"): what it looks like, why the tools produce it, who it hurts, the fix, sources.
- `list_patterns`: List the whole Slop Patterns taxonomy: code, id, name and one-liner for every documented AI design anti-pattern.
- `report_pattern`: Report an AI design anti-pattern that is NOT yet in the library, for a design failure seen repeatedly that a search of the library does not find. Reports are reviewed by a human before anything is published, and published entries credit the reporter.
- `search_patterns`: Plain-language search across the library. "gradient headline" returns A10 Gradient Text Headline.
- `why`: Return only the causal explanation for one pattern — which model, tool or template default produces it.
