A3.7/5.0
Behavior4/5

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

Annotations already declare readOnlyHint, idempotentHint and destructiveHint=false, so safety is covered. The description still contributes real behavioral detail beyond them: results are deduplicated to the latest version of each document and content is omitted, telling the agent what it will and will not receive. It omits ordering and pagination, which keeps it from a 5.

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

Conciseness5/5

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

One sentence, zero filler, with the caveat about omitted content placed at the end where it is read as a qualifier rather than a precondition.

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

Completeness3/5

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

With only two parameters and no output schema, the main open question is what a listing entry contains (slug, title, version, timestamp) and whether results are paginated or ordered — none of which is stated. Adequate for a simple read, but an agent still has to discover the result shape by calling it.

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

Parameters3/5

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

Schema description coverage is 100%, so the room slug format and the token override behavior are already fully documented in the schema. The description adds no parameter-level meaning beyond that, which matches the baseline for full coverage.

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

Purpose4/5

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

States a concrete verb and resource (list shared documents in a room) and adds the scope qualifiers 'latest version of each' and 'without content', which separate it from room_artifact_get and room_read. It never names those siblings directly, so differentiation is inferential rather than explicit.

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

Usage Guidelines3/5

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

Usage is only implied: an agent can infer this is the discovery step before fetching an artifact's content. There is no explicit when-to-use, no stated prerequisite (e.g. room membership), and no named alternative such as room_artifact_get for content.

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