list_accessories

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

With no annotations, the description carries the full burden and does disclose meaningful behavior: results are deduplicated by name and each entry carries `owned` and `usable` flags. It omits auth requirements and pagination/refresh behavior, so it falls short of full disclosure for an unannotated tool.

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?

Two tight sentences: the catalog contents and dedup rule come first, then the actionable follow-up. Every clause earns its place with no filler.

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?

There is no output schema, so the description must convey return shape, and it does cover dedup plus the owned/usable flags. It is slightly thin on the full field set of each catalog entry, but it is adequate for a zero-argument list tool.

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?

The tool takes zero parameters (empty schema), so the baseline is 4; there is nothing for the description to clarify beyond that and it does not misrepresent any inputs.

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 resource (Speediance's accessory catalog) with concrete examples (bars, handles, rope, benches, AeroRow) and clarifies the deduplication key. This clearly distinguishes it from sibling list tools such as list_exercises or list_my_workouts.

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?

The description gives a clear workflow: look up accessories here, then persist ownership via set_preferences(owned_equipment=[names]). It names the complementary tool explicitly, but offers no when-not-to-use guidance or conditions under which the catalog should be skipped.

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