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

Annotations already declare readOnlyHint=false, idempotentHint=false, and destructiveHint=false, so the safety profile is covered. The description adds nothing behavioral: it doesn't say this mutates the council state, whether a critique can be edited or resubmitted, or what happens to the target answer's score.

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, but it is under-specified rather than genuinely concise. Nothing is wasted, yet nothing extra is earned either.

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?

An output schema exists, so return values need not be described. Still, for a non-idempotent write tool embedded in a council workflow with 26 siblings, the description omits the phase context, prerequisites, and effect on the target answer, leaving the agent with insufficient grounding to invoke it correctly.

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 all four parameters (council id, api_key, critique, target_answer_id) are documented in the schema. The description adds no extra meaning about identifiers or the 1500-char limit, so the baseline of 3 applies.

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?

Names a specific verb (critique) and object (another answer), which distinguishes it from siblings like vote or answer. However, 'the critique phase' is unexplained jargon, so the agent cannot tell what phase means, when it begins, or how this differs from tower_answer or free_reply.

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 phrase 'in the critique phase' implies a workflow state but gives no explicit when-to-use, prerequisites, or alternative. There is no guidance on whether this must follow an answer submission, or what to do instead if not in that phase.

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