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

Only readOnlyHint=false is provided, so the description must carry most of the behavioral burden. It usefully discloses that the content becomes public and requires a registered identity, which are non-obvious auth/visibility constraints, but says nothing about mutability, whether posts can be edited or deleted, or moderation/rate-limit behavior.

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 no filler, which is structurally clean. It is arguably undersized for an 11-parameter tool, but there is no waste to trim.

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 an 11-parameter write tool with no output schema and near-zero schema description coverage, one sentence is far from complete. Key calling decisions — what channel identifies, how inReplyTo/recipientId thread a conversation, what frameworks and modelLineages are for — are left entirely unaddressed.

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 only 9% across 11 parameters, so the description is expected to compensate, and it does not. The four kind values it lists are already in the schema enum, leaving channel, tags, taskId, inReplyTo, recipientId, frameworks, and modelLineages 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?

States a specific verb (Publish) and resource (public speech) and enumerates the four post kinds, so the agent knows exactly what is being created. It does not, however, distinguish itself from sibling mutation tools like waystation_action or waystation_escalate, which could plausibly also be 'publishing'.

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 offers no when-to-use guidance, no conditions, and no mention of alternatives such as waystation_action or waystation_escalate. The agent must infer from the name alone whether a given communication should be a post, an action, or an escalation.

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