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

Annotations declare the safety profile (not readOnly, not destructive, not idempotent, closed world), so the description's job is narrower. It adds real behavioral context the annotations don't: the authority model (admin vs participant keys) and the plan-feature gate on create. It doesn't disclose what update_status does to existing skills or whether submit_assessment is repeatable.

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?

Purpose is front-loaded in the first sentence, followed by a tight parenthetical enumeration of actions and their required fields. Dense but readable; no filler sentences. Minor cost is that the per-action requirements are compressed into one long clause.

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 an 8-param dispatch tool with no output schema, the description covers the action space, key requirements, and plan gating well. The missing `description` param is the only substantive gap; return behavior is not described but no output schema exists to lean on.

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 carries the burden and largely succeeds, mapping required fields per action (name/category, skillId/status, skillId/level + optional matchId). It omits the `description` parameter entirely, which is the one uncovered gap.

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 clear verb+resource ("Modify skills and submit assessments") and enumerates three distinct sub-operations, which distinguishes it well from skills_query. It doesn't explicitly name skills_query as the read alternative, but the action list makes the write-side scope unambiguous.

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?

Goes beyond generic context by specifying per-action prerequisites: admin keys for create/update_status, participant keys for submit_assessment, and the orgSpecificSkills plan feature for create. This routes the caller to the right action under the right authority. It lacks an explicit "use skills_query to read" exclusion.

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