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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds nothing beyond that — it does not say whether pricing is a local calculation or a live lookup, what currency/units are used, or how retries factor in.

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. It is efficient, though its brevity stems partly from under-specification rather than disciplined editing.

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 9-parameter, all-required estimation tool with no schema descriptions and no output schema, the description is far too thin. Token-counting conventions, retry handling, aggregation across sub-agents, and the shape of the returned cost breakdown are all absent.

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?

All 9 parameters are required with 0% schema description coverage, and the description compensates for none of them. Ambiguous semantics such as whether retryRatePct is 0-100 or 0-1, and what runsPerDay drives in the estimate, are left entirely 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 (estimate) and resource (cost of an orchestrator + sub-agent swarm run), which implicitly distinguishes it from the single-agent 'agent_cost_estimate' sibling. It is clear but never explicitly names or contrasts with the alternative cost-estimate tools.

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 description gives no guidance on when to choose this over agent_cost_estimate or cursor_auto_cost_estimate, nor any preconditions. The agent must infer the multi-agent scope on its own.

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