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

Beyond the annotations, the description discloses that the tool is single-use, aborts at the first failed or uncertain item, and returns results rather than debug/approval-handle payloads. It does not elaborate on the destructive side effects already flagged by annotations, but it adds useful execution semantics.

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?

Three short sentences each add a distinct piece of information: what is being approved, the token source/exactness, and execution/output behavior. The opening 'Approved status/budget/bid' is slightly awkward but not wasteful.

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 one-parameter confirmation tool with a destructive annotation and an output schema, the description covers the token requirement, failure handling, and response expectation. Nothing essential for calling it correctly is missing.

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 coverage, the description carries the full burden for confirm_token. It defines acceptable values as exact bu_confirm_* or mu_confirm_* tokens obtained from prepare. This turns an unconstrained string into a precise, validated input.

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?

The description identifies the operation as the confirm step for overview status/budget/bid updates and ties it to prepare tokens; the title 'Confirm Overview Update' reinforces this. It is slightly cryptic ('Approved status/budget/bid' is a fragment rather than an explicit 'Confirms...'), but it distinguishes from the deny/update siblings.

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?

It specifies the precondition clearly: the input must be an exact bu_confirm_* or mu_confirm_* token from a prepare call. It also states single-use and early-stop behavior. It does not explicitly contrast with deny/update alternatives, but the 'from prepare' condition leaves little ambiguity.

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