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

Goes well beyond the annotations: it discloses the auth/permission requirement, the mandatory read-before-respond flow, the 409 conflict behavior (re-read and re-confirm), the accept vs reject effects, and that both parties are notified. Annotations only flag it as non-idempotent and destructive, which the description's 'reject clears the proposal' story is consistent with.

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?

A single dense paragraph that front-loads the login/permission gate and then the workflow. Every clause carries operational meaning, though the compact punctuation makes it slightly heavy to parse.

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 mutation tool with no output schema, a nested required object, and conflict handling, the description covers auth, permissions, preconditions, the 409 recovery path, effects of each branch, and notification behavior. Nothing essential for correct invocation 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 description coverage, the description compensates by mapping the nested expectedProposal fields (linkId, proposal bps, side, at) and requiring them to be echoed back verbatim, which explains the optimistic-concurrency contract. allianceId/organizationId are left implicit but are self-evident from the name.

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 (respond) plus resource (alliance-organization share proposal) and the two outcomes (accept takes effect, reject clears the proposal). It also names the related sibling set_alliance_organization_share for the ratio semantics, letting an agent distinguish this responder from its counterpart respond_organization_alliance_share.

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?

Explicit preconditions: login required, only the alliance leader under managePolicy may call it, and you must first read the organization share to confirm the organization, the counterparty's proposed value, and accept. It also states a clear exclusion (you may not respond to a proposal you yourself raised) and points to set_alliance_organization_share for ratio meaning.

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