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

Annotations already declare destructiveHint=true, idempotentHint=false and openWorldHint=true, so the safety profile is covered. The description adds 'with its expected version' (optimistic concurrency) and 'Records the person and outcome', which is context beyond the annotations, but it never says what happens on a version mismatch or that a stale version aborts the write — a material gap for a destructive, non-idempotent mutation.

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?

Two short sentences, front-loaded with the operation set, with no filler. Nothing is wasted, though the brevity itself leaves the parameter gaps above unaddressed.

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?

An 8-parameter, 5-required destructive mutation with 13% schema coverage and no output schema needs far more description than two sentences. Missing version-conflict behavior, conditional assignee requirement, and the meaning of environment leave an agent likely to misfire on a write that alters task state.

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 13% (only idempotency_key is documented), so the description must carry the load and largely doesn't: taskId, company, environment, outcome and assigneeId get no explanation at all. It restates the four operation enum values and hints that version is an expected-version guard, but omits that assigneeId is only meaningful for the 'assign' operation and what the staging/production choice changes.

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?

Names the four concrete operations (complete, dismiss, reopen, assign) against a specific resource, and the 'expected version' phrase marks it as a versioned mutation. It implicitly separates itself from summer_actions_approve by rejecting plan approval, but never names a sibling explicitly, so it stops short of 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 'Does not approve a plan or change customer records' line is a partial exclusion, but it doesn't route the agent to the alternative (summer_actions_approve, summer_human_tasks_list) or state preconditions such as needing a current version or a valid assignee. Usage is only inferable from the verb list.

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