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

The annotations already declare destructiveHint=true and idempotentHint=true, so the description adds real value by disclosing that updates are applied asynchronously (queued) and capped at 100 per call. It does not explain what happens on partial failure or whether an async edit can be undone, which is a gap for a destructive batch 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?

Three short sentences, each carrying distinct information: purpose, addressing key plus async behavior, and batch limit. Front-loaded with the operation and free of filler.

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 destructive batch mutation with no output schema, the description covers addressing, async queuing, and the item cap, which is solid. It stops short of describing per-item success/failure behavior and the consequences of setting status to rejected, which an agent needs before issuing 100 destructive updates.

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 reported at 0%, so the description must compensate; it does partly by explaining that records are addressed by 'click_id + event' and that the batch is capped at 100. It says nothing about how status and payout interact or what currency defaults to, leaving the nested item fields unexplained.

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 and resource: 'Edit already-registered conversions: approve/reject and adjust payout'. The qualifier 'already-registered' implicitly separates it from the sibling import_conversions, which creates conversions, but it never names that sibling explicitly.

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?

'after reconciling with the affiliate network' gives the situational context for calling it, which is genuinely useful. However, there is no explicit when-not guidance, no mention of import_conversions as the alternative for new records, and no stated prerequisites such as required permissions or a valid click_id.

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