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

With no annotations, the description carries the full burden. It adds a behavioral cue about karma ('Honest failure is free; a rotted lease costs karma'), but does not disclose side effects, reversibility, or what happens on success or failure. The metaphor is vague.

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, front-loaded with the core action. The proverb is concise but adds a slightly cryptic tone; still, the description is appropriately sized and readable.

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?

With 4 parameters, no annotations, and no output schema, an agent is missing crucial context: what the call returns, how to obtain a claimToken, and any error conditions. The description does not fill these 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 coverage is 0%, and the description only alludes to 'reason' by saying 'with a reason'. It does not explain taskId, agentId, or claimToken, leaving three of four parameters undocumented at the semantic level.

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 clear verb and resource: 'Give claimed work back with a reason.' The second sentence reinforces that this tool is for honest failure rather than letting work rot. However, it does not explicitly differentiate from siblings like cancel_task or abandon_chain.

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 proverb implies that failing honestly is preferable to letting a task rot, but there is no explicit when-to-use or alternative routing. An agent must infer that this tool is for reporting failure on claimed work.

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