Two fixture tools with minimal descriptions (both ~80 chars, baseline 194) and sparse parameter documentation. fixture_alpha has an enum constraint on 'kind' but no description for the parameter itself. fixture_beta's 'count' parameter lacks type bounds, range, or usage guidance. Neither tool description explains WHEN to use it, WHAT it returns, or WHY it exists beyond 'used by autobuilder capture ACs', insufficient for LLM selection. No output schemas documented. Tools appear to be test fixtures rather than production-grade agent tools, which explains the gaps, but they still fail baseline quality checks for parameter descriptions and output documentation.

• Add parameter descriptions to both tools. For fixture_alpha.kind: 'The variant type (a, b, or c) determining which fixture variant to return.' For fixture_beta.count: 'Number of items to generate (1 - 1000). Deterministic based on seed.'
• Document output schemas. E.g. fixture_alpha returns {variant: string, data: object}; fixture_beta returns {items: array, total: integer}.
• Expand tool descriptions to 100 - 200 chars explaining purpose, return value, and when to use. E.g. 'Returns a deterministic fixture with variant type [a|b|c]. Use to test tool composition with known, repeatable data.'
• Add bounds to numeric parameters: count: 1 - 1000 (or appropriate range for your use case).
• If these are test-only fixtures, consider marking them with a 'test' or 'fixture' prefix in the tool name to signal they are not production tools.
