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

Annotations already declare readOnlyHint=true, so the description's main job is to resolve the name/behavior tension, which it does: 'opens nothing by itself' and 'Returns how to do it in Quora step by step'. It also discloses the external constraint that Quora has no public API, which explains why the browser workaround exists. Minor gap: the shape of the step output (screens, buttons, fields) is mentioned but no format or length expectation is given.

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?

Front-loaded with the action and the crucial 'this only returns steps' caveat, then the browser follow-up, then the API note. Dense but earns most of its clauses; the parenthetical '(checked 27 Oct 2026)' is dated and adds little beyond 'no public API'.

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 no output schema and no parameters, the description carries the burden of explaining what comes back, and it does (step-by-step screens, buttons, fields) plus why an alternative route exists (no Quora API). The remaining gap is that it never contrasts with the similarly named sibling tools an agent will see in the same list.

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 tool takes zero parameters, so there is nothing for the description to disambiguate beyond confirming it is a no-argument call. Baseline applies; the description adds no conflicting parameter hints.

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 specific verb and resource (post to a Space in the user's own Quora account) and explicitly clarifies that the call itself returns step-by-step instructions rather than performing the post: 'opens nothing by itself'. That nuance rescues an otherwise misleading name. It does not distinguish itself from the sibling tools named post_to_space or quora_post_answer, which appear to target the same resource.

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?

Gives a clear follow-on path: use the returned steps, then act with cotlet_browser_* tools in the Quora Cloud Browser. It does not say when to choose this over the sibling post_to_space / quora_post_answer tools, nor any prerequisite such as being logged in or having Space membership.

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