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

Annotations already declare readOnlyHint=false, destructiveHint=true, idempotentHint=true, and openWorldHint=true. The description adds valuable context beyond annotations: new dossiers receive a server-required BID policy, and returned IDs must be reused. It also warns about required steps before final review/submission. This is meaningful behavioral disclosure that complements the annotations.

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 sentences, all informative. The core purpose is front-loaded, followed by the BID policy constraint and the ID reuse instruction. No wasted words, though the BID policy sentence is dense and could be clearer.

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 creation tool with no output schema, the description covers the key behavioral requirements: BID policy, ID reuse, and next-step inspection. It doesn't describe the return value shape, but the 'Returned IDs must be reused' implies an ID is returned. Given the tool's complexity and the lack of output schema, this is reasonably complete, though it could mention what the response contains.

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 idempotencyKey has a description). The description doesn't explain the 'name', 'slug', or 'description' parameters beyond what the schema provides. The idempotencyKey guidance in the schema is already detailed, and the description's 'Returned IDs must be reused' is about the response, not parameters. With low coverage, the description could have compensated but doesn't.

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?

The description states a specific verb and resource: 'Create a current RFP/client dossier in this workspace.' This clearly distinguishes it from sibling tools like helvabase_list_dossiers or helvabase_contribute_dossier. However, it doesn't explicitly name a sibling alternative, so it doesn't fully earn a 5.

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 provides clear context: it's for creating a new dossier, and it directs the agent to inspect helvabase_bid_policy for missing steps. It doesn't explicitly state when not to use this tool or name alternatives, but the 'inspect helvabase_bid_policy' instruction gives actionable routing guidance.

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