get_plugin_catalog

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

readOnlyHint=true already declares the safety profile, so the description's main additive value is that this is learned/tested data summarizing plugins 'at default settings' — a genuinely useful caveat about the nature of the data. It does not state freshness, whether results are cached, or what happens when a plugin is untested.

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?

A single sentence with no padding, so length is appropriate. However the front-loaded 'What creaper has learned' framing is an indirect fragment rather than a clear statement of action, slightly reducing scannability.

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?

No output schema, so the description does partly cover what is returned (roles plus summaries). For a 3-parameter read tool with filter options, though, it omits how filtering works and how it relates to the many neighboring plugin/FX tools, leaving an agent to guess at selection.

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 moderate (67%) with role and search documented in-schema, but the description is silent on all three filters (kind, role, search) and adds no filtering semantics. With coverage not high enough for a free baseline 3, the description fails to compensate for the undocumented 'kind' parameter.

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 ('get') and resource ('plugin catalog') and specifies the content returned: each plugin's roles and a summary at default settings. It names scan_plugins only as the data source, not as an alternative, so it does not differentiate itself from likely-overlapping siblings like list_installed_fx or get_plugin_profile.

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?

No when-to-use, when-not-to-use, or alternative-tool guidance is provided. The scan_plugins reference is about data provenance, not about when an agent should call this tool versus list_installed_fx, get_plugin_profile or scan_plugins itself.

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