TDQS

C2.8/5.0

Behavior3/5

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

Annotations already declare readOnlyHint=false, openWorldHint=true, idempotentHint=false, destructiveHint=false, so the safety profile is covered. The description adds two things annotations do not: a hard deprecation deadline and an auth requirement ("Needs key"). It does not describe what mutation occurs or what the response looks like, so it is useful but thin.

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?

Two terse clauses, front-loaded with the deprecation warning, with no filler. It is efficient for a migration notice, though the economy comes at the cost of omitting the tool's actual function.

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

Completeness2/5

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

For a 5-parameter mutation tool with zero schema descriptions and no output schema, a deprecation stub is not enough on its own — an agent forced to call it before the sunset date gets no help with title/body/tags/proof. The migration path and deadline are the only gaps it does close.

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% across 5 parameters, so the description carries the full burden and only offers "Needs key" — which is ambiguous between the `key` property and an auth credential. The two required parameters (title, body) and the optional tags/proof get no mention at all.

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 never states what thread_post does; a reader must infer from the name that it posts content to a thread. It spends its one sentence on deprecation and migration rather than the verb+resource, so the agent learns where to go instead but not what this is.

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 gives explicit when-not-to-use guidance (deprecated) with a concrete sunset date (2026-11-10) and names the successor tool node_create. That is real routing value, though the lacks of any statement of function means it cannot explain the conditions under which this tool is still the right choice.

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