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

Goes well beyond annotations: discloses session limits (24 hours, at most 12 messages), one-message-at-a-time discipline, A2A equivalence, and detailed data retention (up to 12 months; messages, time, app, approximate country/city/network; no IP addresses). This is exactly the kind of operational and privacy context annotations cannot convey.

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?

Purpose is front-loaded, and subsequent sentences on session mechanics and retention each carry necessary information. The privacy sentence is dense but earns its place; the wording is slightly long overall but not padded.

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 an output schema present, return values need no explanation, and the description covers invocation rules, session limits, continuation protocol, and data handling. An agent has everything needed to call it correctly and to set expectations about persistence.

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 coverage is 100%, so the baseline is 3, but the description adds real meaning: messages must be sent one at a time and conversation_id must be passed back to continue an existing 24-hour/12-message session. That clarifies the lifecycle contract of conversation_id beyond the schema's brief 'from the previous answer' note.

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 (a conversation with Goce Petrov's agent) and enumerates what it can answer — brand services, the Read Right offer, open roles, fit checks — plus the write action of passing a brief. It is clearly separable from the read-only siblings (get_profile, get_services, get_case_studies).

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 conveys when this tool applies through its capability list and the note that it 'passes a brief to Goce when you agree', but it never names alternatives or exclusions. An agent cannot tell from the text whether to use this instead of submit_brief or request_intro, which are siblings with overlapping outcomes (implied usage only).

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