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

Annotations already declare destructiveHint=true, readOnlyHint=false, and idempotentHint=false, so the safety profile is covered. The description adds genuinely new behavioral context beyond that: the delete cascades to child batches and works, which tells the agent what collateral damage to expect before invoking.

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?

One sentence, front-loaded with the action and immediately qualified by the cascade scope. Nothing redundant, nothing padded.

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 one-parameter destructive tool with no output schema and annotations covering the safety flags, the key missing piece an agent needs — that the deletion is cascading — is present. Only the reversibility/undo question (and the archive alternative) is left unstated, which is a minor gap given the destructiveHint.

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% and the single 'id' parameter is documented as 'Id of the Project.' The description adds nothing about identifier format or source, so the baseline 3 for a fully-documented single-param schema is appropriate.

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?

Specific verb ('Delete') plus resource ('project'), with added scope detail that everything beneath it (batches and works) is removed. It does not differentiate itself from the nearby archive_project/unarchive_project or the other delete_* siblings, so an agent gets a clear purpose but no routing signal.

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?

No when-to-use guidance, no prerequisites, and no mention of the obvious alternative archive_project for a reversible removal. The sibling set is dense with archive/unarchive/delete variants, yet the description offers no condition for picking this one over them.

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