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

Annotations already declare mutation, non-idempotency, and non-destructiveness; the description adds genuinely new context beyond them: the auth scoping ('your authenticated principal') and the authorization boundary ('does not grant signing authority'). It still leaves out what state change occurs on the task and what happens on a repeat/duplicate accept, which is the main missing behavior.

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, the action and target are front-loaded, and the authorization caveat follows immediately. 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?

For a simple single-parameter mutation with no output schema, the description covers the action and the key caveat, but omits the parameter's identity and the post-accept state change/error conditions. Adequate but with clear gaps an agent would want filled.

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?

There is one parameter at 0% schema description coverage, and the description says nothing about it. The agent must infer from the name alone that 'id' is the review task UUID, and the description never confirms that it is the task id rather than, say, a bounty or artifact id.

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 ('Accept a task') and names the target ('assigned to your authenticated principal'), which distinguishes it from sibling verbs like assign_review_task and list_review_tasks. It does not explicitly name a sibling alternative, so it stops short of 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?

The phrase 'assigned to your authenticated principal' implies the precondition (a task must already be assigned to you), but there is no explicit when-to-use vs when-not guidance and no pointer to list_review_tasks for discovering the id. Usage is implied rather than stated.

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