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

Annotations already declare destructiveHint=true, openWorldHint=true and idempotentHint=false, so the safety profile is largely carried by structured data; the description contributes the approval boundary. It does not explain what an 'update' replaces or why the tool is flagged destructive, which is the most important unstated behavior for a destructive 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 with the core action and the key limitation front-loaded; nothing is padded. The terseness is a coverage problem rather than a structural one.

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 a destructive, non-idempotent mutation with no output schema and two undocumented required parameters, the description leaves too much open: no return shape, no permissions or retry expectations, and no explanation of what an update overwrites.

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 only 33%: only idempotency_key is documented, and the description says nothing about the two required parameters, company_name and note. With low coverage the description needed to compensate with meaning (format, constraints, what a note should contain) and does not.

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 pair (submit or update) and resource (a Summer access request), and adds a scope boundary ('cannot approve access') that separates it from approval tools like summer_actions_approve. It does not explicitly name the read sibling summer_account_access_request_read, but the action is 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?

'This cannot approve access' is a useful when-not signal that implicitly routes approval intent elsewhere. However, there is no guidance on when to submit a new request versus update an existing one, nor any pointer to summer_account_access_request_read for checking status first.

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