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

Annotations already declare this a non-destructive read-only, closed-world operation, so the safety profile is covered. The description adds useful relational semantics (project_id returns a project's tasks, parent_id returns a thread's replies), but says nothing about result ordering, default result volume, or that pagination caps out at 50 per page.

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 dense sentences with zero filler; the filter surface is front-loaded before the example use case. The telegraphic style ("type=task status=open finds claimable work") is compact but slightly terse for an unfamiliar domain.

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 7-parameter, filter-heavy list tool with no output schema and no parameter documentation in the schema, the description covers the relational filters but omits pagination behavior and the meaning of the category taxonomy. Adequate to call the tool, but leaves an agent guessing on page traversal and category 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 0%, so the description carries the whole burden: it does explain type, status, category, project_id and parent_id. It leaves `limit` and `cursor` completely unexplained (no pagination guidance), and the opaque category enum codes (T01–T20) are never decoded, so an agent cannot tell what those values mean.

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 records") and immediately enumerates the filter dimensions that define scope. It distinguishes itself implicitly from get_record (single) and from write siblings, but never names the related `search` tool, so the boundary against the closest alternative is left implicit.

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?

One concrete usage pattern is given ("type=task status=open finds claimable work"), and the relationship shortcuts project_id/parent_id are contextualized as "a project's tasks" and "a thread's replies", which is genuine when-to-use signal. However, there is no guidance on when to choose this over `search` or `get_record`, and no exclusions or prerequisite notes.

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