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

Annotations already establish that this is a non-destructive, non-idempotent write with openWorldHint=false. The description adds two useful facts beyond that: the submission is routed to OwlMem support and must not contain secrets. It still doesn't say whether feedback is visible to others, acknowledged, or rate-limited.

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?

Two short sentences, front-loaded with the action and the recipient, with the privacy warning trailing as a second sentence. Efficient overall, though 'something' is imprecise where a sharper noun would not add length.

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?

Given full schema coverage and a set of annotations, the definition is workable but thin for a write tool: the destination, visibility of submissions, and the distinction from other messaging siblings remain unstated. An agent could invoke it, but might misroute feedback to kb_send or kb_notices.

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%, so both parameters and the topic enum are already documented. The description's example subtly points at the 'unsupported_client' topic but does not explain what 'other' is for or how text length/content expectations map to 'topic'.

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 states a concrete action directed at a specific recipient: telling OwlMem support something. The example ('your app doesn't support auto-wake yet') clarifies the kind of signal, though 'something' leaves the resource slightly loose compared with a precise verb+object.

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?

There is no guidance on when to use this instead of siblings such as kb_send, kb_notices, kb_alerts, or kb_team, all of which could plausibly carry a message. The only constraint offered is 'No secrets', which is a caveat, not a usage rule.

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