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

Annotations declare readOnlyHint=false and idempotentHint=true, so the mutation/idempotency profile is already structured. The description adds genuinely new consequence information: acceptance is 'never a contract, charge, assignment or dispatch,' which tells the agent exactly how far the commitment reaches. It stops short of saying what record is produced or whether acceptance closes the conversation.

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, front-loaded with the action and immediately followed by the required input and the safety caveat. No filler and nothing repeated from structured fields.

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 5-parameter mutation with no output schema, the description covers the effect and the key input but omits the post-acceptance state (what is recorded, whether the proposal is consumed, whether the conversation closes) and says nothing about the auth-token parameters. Adequate to call correctly, but thin for a state-changing operation.

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 60%; the description reinforces the revision parameter ('the revision you read') but that constraint is already in the schema. It adds nothing about proposal_id, which is required yet undocumented in both schema and description, nor about the optional note or the two token parameters.

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 and resource ('Accepts the human's current revision as nonbinding terms') and scopes it to the current revision, which distinguishes it from counter_nonbinding_proposal and withdraw_nonbinding_proposal without naming them. The 'nonbinding' qualifier further pins down what kind of acceptance this is.

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?

'Pass the revision number you read' gives the calling condition implicitly: you accept a revision you have already read. However, there is no explicit guidance on when to choose accept versus counter versus withdraw, and no stated prerequisites (e.g., that a proposal must exist and be open). Usage is inferable rather than spelled out.

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