item_progress

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It implies a mutation but does not explain whether progress affects item state, whether the message is stored or broadcast, whether claim_generation is checked for concurrency, or what permissions or side effects are involved.

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?

The definition is a single front-loaded sentence with no wasted text. However, it is under-specified for a 6-parameter mutation tool, and the word 'meaningful' is vague rather than informative.

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 mutation tool with 6 parameters, no annotations, no output schema, and zero schema description coverage, one sentence is not enough. The purpose is conveyed, but prerequisites, parameter usage, and expected behavior are largely absent.

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?

The schema has 6 parameters with 0% description coverage, and the description mentions none of them. It does not explain id, message, agent_token, claim_generation, client_agent_id, or client_session_id, so an agent must infer their meaning entirely from field names.

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 states a specific verb and resource: record progress on a claimed item. This distinguishes it somewhat from completion or general update siblings like item_done and item_update, though it does not name them explicitly.

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 'your claimed item' implies a prerequisite that the caller must hold a claim, which is useful context. However, it gives no explicit guidance on when to use this instead of item_update, note_add, or item_done, and no exclusions or alternatives are named.

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