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

Annotations already cover the safety profile (readOnly, idempotent, non-destructive, closed-world), so the description's added value is its disclosure of *what comes back* — five named content buckets — which is meaningful given there is no output schema. It stops short of stating ordering, volume limits, or how an empty inbox is represented, so it is helpful but not fully transparent.

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?

A single front-loaded sentence with the core promise ('Everything you should act on, in one call') stated first, followed by the category enumeration. The five-item parenthetical list is dense but each entry carries information; no filler sentences.

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?

For a zero-required-parameter read aggregate with no output schema, the description supplies the most important missing piece — the shape of the result. Remaining gaps (pagination, ordering, whether unread counts are included) are modest for a triage tool whose annotations already establish it as a safe read.

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 sole `token` parameter is documented thoroughly in the schema itself, including the guest-requester override use case. The description adds nothing about the parameter, so the baseline of 3 applies — the schema does all the work here.

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 concrete resource — an aggregated inbox — and enumerates exactly which five item categories it returns (skill-matched offers, to_deliver, to_review, in-progress requests, unread rooms). That is far more specific than a tautology like 'Your inbox', and the aggregate framing implicitly separates it from single-domain siblings such as list_requests or rooms_list, though no sibling is named 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 only implied: 'in one call' hints that this is the preferred entry point over fanning out to several list tools, and 'everything you should act on' suggests a triage-first workflow. There is no explicit when-to-use/when-not statement, no mention of whether to prefer this over rooms_list or list_requests for a specific domain, and no guidance on using it before acting.

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