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

Annotations already declare the mutation profile (readOnlyHint=false, idempotentHint=false, destructiveHint=false, openWorldHint=true), so the safety burden is largely covered. The description usefully adds that accepting 'does not grant signing authority,' clarifying the scope of the state change, but says nothing about failure modes (e.g., accepting a task not assigned to you) or the resulting state.

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 sentences, both front-loaded and free of filler; the constraint about signing authority is stated immediately after the action. Nothing is wasted, though the brevity comes partly from under-specification rather than tight editing.

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?

Annotations cover the safety profile and no output schema exists, so return values need not be explained. However, for a mutation tool with 0% schema description coverage, the description omits error behavior, prerequisites, and what state change accepting produces, leaving real gaps.

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 burden for the single `id` parameter and provides nothing beyond the schema's `string`/`uuid` typing. For a one-parameter tool where the id is self-evidently the review task identifier, this is minimally acceptable but adds no real meaning.

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?

The description names a specific verb+resource ('Accept a task') and scopes it to 'your authenticated principal,' which is more precise than the bare name. It doesn't explicitly contrast with siblings like assign_review_task or list_review_tasks, so it falls short of a 5.

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?

It implies a precondition (the task must already be assigned to your principal) but gives no explicit when-to-use guidance, no when-not to use it, and never names alternatives such as list_review_tasks or assign_review_task. An agent must infer the workflow context from the sibling names alone.

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