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

Annotations already declare readOnlyHint=false, idempotentHint=false and destructiveHint=false, so the agent knows this is a non-idempotent but non-destructive POST. The description adds that attestation output is optional, but says nothing about required credentials, whether a decision is recorded/consumed, or side effects of the POST.

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?

One tightly written sentence that front-loads the operation and appends the endpoint cheaply. No filler, though the endpoint path is only marginally informative.

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 single-parameter authorisation endpoint with no output schema, the description covers the gist but omits what a decision response looks like and whether the call has side effects or quota costs. Adequate but with visible gaps.

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?

Only one parameter exists (body) and schema description coverage is 100%, so the baseline is 3. The description does not expand on the request body beyond naming the resource/action semantics it represents.

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 states a specific verb and resource: check whether a verified AI agent is allowed to run a given action against a named resource, and it names the endpoint. It is a genuine authorisation-decision tool, distinguishable from sibling verification tools, though it does not explicitly contrast itself with affix_agent_trust_verify or affix_verify.

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?

There is no guidance on when to call this versus the many adjacent trust tools (affix_agent_trust_verify, affix_delegate_verify, affix_gate_verify, affix_verify_policies). The usage context is only implied by the word 'authorise'.

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