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

Annotations already declare it is a non-read-only, non-destructive, non-idempotent, closed-world mutation, and the description adds real context on top: fixed 24-hour lifetime, exact return payload, secret-handling instruction, and the guarantee that only project state (never prompts or analytics) is stored. No rate limits or capacity limits are mentioned, which is the remaining gap.

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 purpose and lifetime, then the return values, then handling instructions. Most sentences earn their place, though the trailing 'Begin with read_session and edit_session; no account is needed' bundles two unrelated points awkwardly.

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, the description usefully enumerates return values (sessionId, token, editorUrl, revision, state) and states the expiry, so an agent knows what it gets back. The undocumented 'name' input is the one incompleteness.

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?

Schema description coverage is 0% and the single 'name' parameter is never mentioned in the description, despite the odd default 'Agent preset' that an agent would benefit from having explained. The description does compensate by documenting return fields, but not the input.

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 (create a private temporary collaborative workspace) with a concrete distinguishing trait, the 24-hour expiry. It also names read_session and edit_session as the follow-on tools, so an agent can place it among the siblings without opening any schema.

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 clear operating context: no account needed, share editorUrl with the user, keep the token private, and continue with read_session/edit_session. It stops short of stating when NOT to use this (e.g., when a session already exists and checkpoint_session or restore_session applies).

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