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

Annotations already declare readOnlyHint=true, destructiveHint=false and idempotentHint=true, so the safety profile is covered. The description adds meaningful behavior beyond that: the tool returns procedural guidance instead of mutating state, opens nothing by itself, and requires a browser-tool follow-up in the user's Officient Cloud Browser, which is exactly the context an agent needs before calling it.

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 second sentence is dense and front-loads the key behavior, but the opening clause 'from ChatGPT, Claude or any AI agent' is filler, and the closing note about Officient's official API and the 'checked 22 Oct 2026' provenance take space without helping an agent decide or act. Information is present but not tightly trimmed.

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 full annotation coverage, the description supplies what is needed: what it returns (screens, buttons, fields), that it performs no action itself, and which tools carry out the actual change. Scope could be tightened to say explicitly that only the user's own personal information is covered, but overall it is complete for a guidance tool.

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 no parameters, so there are no argument semantics to explain and the baseline for a zero-parameter schema applies. Nothing in the description misrepresents or omits parameter meaning.

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 resource (personal information in the user's own Officient account) but the headline verb is 'Update', while the tool actually 'Returns how to do it in Officient step by step' and 'opens nothing by itself'. The first sentence reads like a mutation tool, so an agent must read the second sentence to learn the real function, which is a clarity gap rather than a clean distinction.

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?

The description gives a clear follow-up path: call this first for step-by-step screens/buttons/fields, then execute with the cotlet_browser_* tools in the Officient Cloud Browser. It does not say when to use this versus cotlet_app_guide, nor when it is inappropriate (for example, editing someone else's record or non-personal Officient data), so the routing guidance is only partially explicit.

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