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

With no annotations, the description carries the full burden, and it does disclose the key behavioral trait: submission is immediately visible to all peers, i.e. a public side effect rather than a private draft. It omits whether submissions overwrite prior ones, whether they can be retracted, and what permissions or identity constraints apply.

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 with no filler, and the core action is front-loaded before the visibility note. The brevity edges toward under-specification, which is penalized elsewhere.

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?

A required-parameter mutation tool with no annotations and no output schema needs more: parameter meanings, what happens on success, error conditions, and how it relates to sibling tools are all absent. Only the peer-visibility behavior is covered.

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%, so the description must compensate and it largely doesn't. 'Your method' loosely maps to the 'method' parameter, but the required 'agent' parameter is never explained (is it the submitter's name, an ID, a handle?).

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 (submit), resource (method) and destination (blackboard), which distinguishes it from the read-side sibling read_blackboard. It does not explicitly contrast with deposit_asset or validate_note, but the verb+resource pairing is unambiguous.

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 explicit guidance on when to use this tool versus siblings like deposit_asset or validate_note, nor any prerequisites or exclusions. 'All peers see it immediately' hints at a broadcast use case but the agent must infer it.

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