update_project_deadline

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

The description lacks disclosure of behavioral traits beyond the implied mutation. No annotations are provided, so the description carries full burden. It does not state whether the update is partial or full, idempotent, requires specific permissions, or what happens to omitted fields.

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?

The description is concise at one sentence, but it is too terse and lacks structure. It could be expanded to include key details without becoming verbose. The conciseness is adequate but not optimal for clarity.

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?

Given the 5 parameters, no annotations, and the existence of sibling tools and an output schema, the description is incomplete. It does not explain how the update works, what fields are updateable, or any side effects. A more complete description would cover common usage and constraints.

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?

With 0% schema description coverage, the description adds minimal meaning. It implies that the deadline is associated with a project, which helps understand project_id, but does not clarify the purpose of name, due_date, or fields_json. The output schema exists but does not compensate for parameter semantics.

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 clearly states the verb 'Update' and the resource 'a deadline on a project', which is adequate but very generic. It does not distinguish this tool from siblings like create_project_deadline or get_project_deadline, as it only specifies the action without scope or details.

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 guidance is provided on when to use this tool versus alternatives such as create_project_deadline or delete_project_deadline. There is no mention of prerequisites, required fields, or constraints like whether the deadline must exist or be editable.

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