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

Annotations already declare destructive=true, idempotent=true and openWorld=true; the description adds real context on top by naming the external side effect (dispatch of a contact notice) and explaining that authority derives from the current explicit grant, actor membership, and the operation/resource contract. It stops short of saying what is destroyed or whether dispatch can be undone, which matters given destructiveHint=true.

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?

The action and its side effect are front-loaded in the first clause, and the remaining sentences are short constraint statements. Some phrasing is abstract to the point of vagueness ("existing operation/resource contract"), which costs a little density of meaning per sentence.

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?

With an output schema present and full parameter documentation, the description only needs to cover authority and side-effect semantics, which it largely does. The remaining gap is what happens on confirmed=false and how repeat calls behave (idempotency is only in annotations).

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 100%, so baseline would be 3, but the description genuinely adds semantics the schema lacks: confirmed is a decision value rather than evidence of human presence, and true can trigger a notice dispatch. The other three UUID parameters are left entirely to 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 and resource ("Records attributable release evidence") plus the consequential side effect ("confirmation can prepare AND dispatch a contact notice"). However, "attributable release evidence" is jargon, and the description never distinguishes this from close siblings like engineering_approve, engineering_reject, or engineering_reconcile, so an agent must infer the boundary.

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 supplies two negative rules: confirmed is never independent proof of human presence, and a completed tracker issue alone does not establish release or contact receipt. Those are useful guardrails, but there is no positive "use this when…" statement and no explicit routing to the sibling approval/rejection tools that an agent would otherwise consider.

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