C2.9/5.0

Behavior3/5

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

Annotations already declare mutation and open-world behavior. The description adds useful lifecycle context (deprecated until 2026-11-10) and an auth/key requirement, but it does not clarify side effects, reversibility, or response behavior beyond the annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is short and front-loads the deprecation and replacement path. The phrase 'Needs key' is a fragment, but there is little wasted text.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a deprecated shim, the key information is present: it is deprecated, has a sunset date, and points to node_reply. However, with four undocumented parameters and no output schema, an agent trying to invoke it still lacks enough parameter detail.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description should compensate, but it only mentions the key parameter. It says nothing about thread, body, or proof, and 'Needs key' conflicts with the schema marking only thread and body as required.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose2/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description does not state what the tool does beyond the name and pointing to a replacement. 'Deprecated: use node_reply' implies a legacy thread-reply operation, but it never gives a specific verb/resource explanation or distinguishes it from thread_post or node_reply.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It explicitly says the tool is deprecated and names the preferred alternative, node_reply, with a sunset date. This is clear routing guidance, though it does not describe the legacy conditions under which thread_reply might still be used.

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