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

The annotations already declare readOnlyHint=true and destructiveHint=false, and the description reinforces this with the explicit 'opens nothing by itself', removing any doubt about side effects. It also discloses the return content (step-by-step screens, buttons, fields) and the notable backend fact that Peerspace has no public API, developer portal, or webhooks — context an agent cannot get from annotations. Missing only details like whether the steps are cached or versioned.

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 core workflow and the no-side-effects caveat are front-loaded and useful, but the opening phrase 'from ChatGPT, Claude or any AI agent' is marketing padding that adds nothing for tool selection. The trailing API-availability note is valuable but appended as a fragment rather than integrated, making the description slightly longer than it needs to be.

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 zero parameters, no output schema, and read-only annotations, the definition covers what an agent needs: what it returns, that it is side-effect free, and which sibling tools perform the actual action. The only gap is that it does not say what the response looks like structurally (text vs. structured steps), which matters since there is no output schema to fall back on.

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 the baseline is 4; there is no parameter meaning for the description to add or omit. The description correctly implies the tool needs no arguments because everything is derived from the user's connected Peerspace account.

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 names a specific verb and resource (reply to a Peerspace inquiry) and then immediately corrects the likely misreading by stating the tool 'Returns how to do it in Peerspace step by step (screens, buttons, fields)'. It distinguishes itself from the cotlet_browser_* siblings by positioning them as the actual executors. It loses a point because the name/title imply the tool performs the reply, so the true purpose only becomes clear after reading past the first clause.

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?

It gives a clear two-step workflow: call this to get instructions, then act with the cotlet_browser_* tools in the Cloud Browser. It does not compare against the other Peerspace siblings (peerspace_accept_booking, peerspace_send_custom_proposal) or cotlet_app_guide, so an agent choosing among related tools still has to infer which one applies.

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