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

With no annotations, the description carries the full burden and does disclose the key behavioral trait: this is a stateful publish gated on a prior status check, with an ordering constraint tied to the user's next message. It does not state failure behavior, idempotency, or whether repeated publishes are safe, which is a real gap for a mutation tool.

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?

Front-loaded with the verb and endpoint, then parameters, then the status vocabulary, then the gating rule — a logical order with no filler. The parenthetical status glosses are dense but each carries a distinct instruction, and nothing is redundant enough to penalize heavily.

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 2-param tool with no annotations and no output schema, it covers the workflow and return-state vocabulary reasonably. However, it never explains how this consent gate relates to sibling action tools (cube_create, cube_vote), which is the main ambiguity an agent would face when deciding whether and when to invoke it.

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 coverage is 0%, and the description fully compensates: it defines action=status|notice_shown and explains msg_ref as 'id of the current user message (e.g. t648u)' with a concrete example. It does not say whether msg_ref is required for each action, nor mention that action defaults to status, so it is not a 5.

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 concrete verb and resource ('Publish consent') plus the backing endpoint (POST /cube/consent), and enumerates the two action modes (status, notice_shown), so an agent knows exactly what the tool does. It does not differentiate itself from siblings such as cube_create or cube_vote, which keeps it out of 5 territory.

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?

Gives explicit conditional guidance: call notice_shown when status=notice_required, and 'publish only after the user's next message' when status=notice_pending, plus the hard rule 'Publish only when status=allowed'. What it lacks is any reference to alternative tools or what to do on error/unknown, so it stops short of full when/when-not coverage.

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