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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so safety is covered. The description adds genuine value beyond that by disclosing the shape of the response: conversation content plus the outcome of confirmations and a waiting-on-user flag.

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?

One sentence, front-loaded with the verb and resource, with the two payload qualifiers appended compactly. No filler or redundancy.

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 only one optional parameter, the description carries the return-value burden and does so adequately by naming what the read yields (confirmation outcomes, waiting state). Minor gap: no indication of conversation history length, ordering, or whether past conversations are retrievable.

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 100% and the single 'team' parameter is fully documented in the schema, including the conditional 'only when the user belongs to more than one team.' The description adds nothing about parameters, so baseline 3 applies.

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+resource: 'Reads the user's current conversation with Capital Company's assistant.' It also scopes the payload (confirmation outcomes, waiting state), which separates it from write-oriented siblings like capital_company_reply or capital_company_confirm. It stops short of naming those siblings explicitly.

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?

Usage is implied rather than stated — the agent can infer this is the tool for checking conversation state, and the mention of 'whether it is waiting on them' hints at a status-check use case. There is no explicit when-to-use, when-not-to-use, or named alternative (e.g., capital_company_show_confirmation).

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