Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

The annotations already declare readOnlyHint=true, openWorldHint=true and destructiveHint=false, so the safety profile is covered. The description adds real context beyond that: the catalog is community-published third-party content and installation is a separate mutating step via recipe_install. It does not discuss pagination or whether results can be stale.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Front-loads the definition, then usage, then the next action — a sensible ordering. The concrete examples ('a morning brief, inbox triage, a weekly report') earn their space, but the second sentence restates 'ready-made' already established in the first, costing a little redundancy.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a read-only discovery tool with an output schema, full parameter coverage and complete safety annotations, the description covers purpose, rough return shape and the follow-up action. The one real gap is that it never positions itself against recipe_list/recipe_get in a very crowded recipe_* sibling set.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% and the single 'category' parameter is fully documented in the schema, including the important caveat that it is only a filter hint and everything is returned. The description says nothing about the parameter, so it does not add meaning beyond the schema — the baseline 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ('Browses installable community SKILLS') and qualifies the resource as third-party published workflows, which implicitly separates it from the rest of the recipe_* family. However, it never names the closest sibling (recipe_list), so an agent must infer the community-vs-own distinction rather than being told.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Gives a clear use scenario ('a repeatable multi-app task instead of building it from scratch') and explicitly routes forward: 'install one with recipe_install(id).' It does not state when to prefer recipe_list or recipe_get instead, so the family-level selection guidance is incomplete.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
