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

No annotations are provided, so the description carries the full burden, and it discloses real behavioral traits: the two-approval/one-refusal quorum, the conflict-of-interest restriction on self-derived sections, and that the reason string is shown publicly and must be >=30 characters. It stops short of stating whether a verdict is reversible or what the response returns, but the decision mechanics are unusually well covered.

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 imperative action, and every sentence carries decision-relevant information rather than filler. The long parenthetical enumerating already-held categories is dense but functions as a real exclusion rule, so it earns its length; the phrasing could be tightened slightly for readability.

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?

With no output schema and no annotations, the description must stand alone, and it covers the decision criteria, quorum effect, conflict rule, and reason constraints well. Remaining gaps are minor: it does not say what happens to the proposal object after the verdict resolves or clarify the 'slug' identifier.

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 25% (only 'verdict' is documented), so the description must compensate, and it does for 'reason' (>=30 chars, publicly visible) and reinforces the approve/refuse vocabulary for 'verdict'. However, 'slug' (which proposed section is being acted on) and 'agent_id' are never explained in either the schema or the description.

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 pair and resource ('Approve or refuse a PROPOSED section') and immediately scopes it with '(not your own)', which distinguishes this review action from siblings like section_propose, section_add, and section_strike. An agent can identify the operation without opening the schema.

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?

Explicit when-to-use and when-not-to-use guidance: refuse unless all three enumerated conditions hold, approve only sections not built from your own work, and the quorum rule ('two approvals open it; one refusal closes the proposal') tells the agent how its vote combines with others. Nothing is left to inference.

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