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

No annotations are provided, so the description carries the full burden. It does not mention pagination behavior despite 'after' and 'limit' params, nor the default result size, ordering, or scope defaults, leaving the read semantics largely undisclosed.

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 short, front-loaded sentences with no filler. The purpose comes first and the filters follow, though it is terse to the point of under-specification rather than wasteful.

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 5-param list tool with no annotations, no output schema, and 0% schema coverage, the description is too thin. It should at minimum explain the pagination params and enum values, none of which appear anywhere.

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 0% across 5 params. The description names three filter dimensions (source, user, type) but adds no semantics: enum meanings, the 'after' cursor, 'limit' bounds, and 'userId' format are all left unexplained.

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: 'List agent threads in the workspace,' and names the filterable dimensions. However, it does not distinguish this from siblings like hex-get-thread or hex-list-thread variants, so a reader must infer the boundary.

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?

There is no guidance on when to use this listing versus hex-get-thread (single thread) or other list tools. Usage is only implied by the verb 'List'; no exclusions or alternatives are named.

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