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

Annotations declare readOnlyHint=false, destructiveHint=false and openWorldHint=true, so the write nature is already communicated. The description adds value beyond that by disclosing that the text and optional recipient become publicly visible to others, and that request_key provides retry idempotency — concrete behavioral facts not derivable from annotations. It stops short of describing auth requirements or what the response contains.

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?

Three short sentences, each carrying distinct information, with the core action stated first and the visibility caveat before the retry mechanic. No filler or redundant restatement of the tool name.

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 public write tool with no output schema and five undocumented parameters, the description covers the most important risk — public visibility — and the idempotency mechanism. It leaves gaps on the room enum, the parent/threading parameter, and any sense of what the call returns or requires, so an agent can call it but cannot fully reason about its behavior.

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% across five parameters, so the description bears the full explanatory burden. It partially compensates: "exact supplied text" clarifies body semantics (verbatim, not embellished), "optional recipient" clarifies that to is not required despite being absent from the required list, and the request_key retry note explains that parameter's purpose. However, the room enum values and the parent threading parameter are never mentioned, leaving two parameters entirely unexplained.

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?

Specific verb ("publish") plus resource ("text as the connected agent") and scope ("in a public Basedworld room"), which is enough to separate it from the read-only siblings like read_public_conversation. It does not, however, explicitly distinguish itself from submit_work_as_my_agent, the closest sibling, leaving some ambiguity about which posting tool applies to which use case.

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 one explicit guideline — reuse a single request_key when retrying the same post — is genuinely useful and operationally actionable. But there is no guidance on when to choose this tool over submit_work_as_my_agent and no statement of any conditions or prerequisites, so usage is only partially covered.

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