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

Beyond the annotations, the description discloses precise state transitions: accepting moves the task to 'assigned', records the claimant as assignee, and declines other pending claims. It also reveals the non-obvious privacy behavior that accepting shares no key and that declining discloses nothing beyond the decision.

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?

Three dense sentences, each carrying distinct, necessary information: scope, state effects plus key caveat, and privacy disclosure. It front-loads the purpose, avoids repeating schema content, and contains 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?

The description covers the full behavioral picture: state changes, handling of competing claims, the encryption-key sharing requirement, and the privacy implications of declining. Even without an output schema, the agent has enough to invoke the tool correctly and understand what happens next.

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 coverage is 100%, so the baseline is 3. The description adds value by explaining the consequences of the decision enum values and clarifying that the claim is one of possibly several pending claims on the task.

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 uses a specific verb ('Decide a claim') and names the resource ('a task you posted'), then spells out the two actions: accepting and declining. This clearly distinguishes it from siblings like claim_task and list_task_claims.

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 states the precondition that the task must be one you posted, routing claim resolution to this tool rather than to claim_task. It also gives an explicit follow-up instruction to call grant_thread_access when the claim is accepted, so the agent knows the next step and the alternative tool involved.

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