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

Annotations already declare non-read-only, open-world, non-idempotent and destructive behavior, so the safety profile is largely covered. The description adds the useful scope note that it cannot approve, but says nothing about what an update overwrites or what the request returns, so it does not fully exploit the lower bar.

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, front-loaded sentences with no wasted words. It is efficient, though arguably terse for a destructive 3-param mutation, keeping it just shy of a 5.

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 a mutation tool with destructiveHint and no output schema, the description covers purpose and scope but omits update-vs-create semantics and field expectations. Together with annotations this is minimally adequate but leaves real gaps.

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 33% (just idempotency_key) and the description mentions no parameters at all, so it fails to compensate for the undocumented company_name and note fields. The names are somewhat self-describing but the description adds zero semantic value over the schema.

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 (submit/update) and resource (Summer access request), and the second sentence scopes it by excluding approval. It clearly contrasts in spirit with the 'access_request_read' sibling, but never names it explicitly, so it stops short of a full 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?

'This cannot approve access' implies a boundary (use another tool to approve), which is a partial when-not signal. However there is no explicit when-to-use statement, no prerequisites, and no named alternative, so guidance is only implied.

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