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

Annotations already declare idempotency, non-read-only, and destructive hints, but the description adds genuinely new behavioral facts: assignments grant no approval rights, email notifications are queued subject to access and recipient preferences, and delivery is not confirmed. That is real context beyond the structured hints, though it never explains the destructiveHint=true implication.

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?

Four dense but purposeful sentences, front-loaded with the core action. Each sentence carries distinct information (idempotency, revision return, approval semantics, notification behavior), though the last sentence is somewhat packed.

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?

No output schema exists, and the description compensates by noting it returns an exact revision for later updates. Combined with the kind/target semantics and notification caveats, it gives an agent enough to call the tool correctly for a moderately complex 3-parameter tool.

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 coverage is 67% and the schema supplies const/enum values but no prose for the complex item oneOf. The description compensates by describing the four item kinds and the target link types (requirement, draft section, proof version, document-plan item), giving meaning beyond the raw schema structure.

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 ('Add') and enumerates the four record kinds it creates (project deadline, assignment, comment, clarification), which clearly separates it from the update-oriented sibling helvabase_update_work_item. The purpose is unambiguous, though it does not name the sibling it differs from 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?

The phrase 'Returns an exact revision for later updates' hints that a separate update path exists, and the targeting options give context, but there is no explicit when-to-use / when-not-to-use guidance or named alternative. Usage is implied rather than stated.

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