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

Annotations cover the read-only/idempotent safety profile, and the description adds genuinely new operational context: public no-auth access, the JSON-LD/HMAC-SHA256 signed receipt semantics, and the post-hoc regulator verification purpose. It doesn't cover failure modes (e.g. unverified publisher) or rate limits, but the added behavioral detail is substantial.

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 core action and scope are front-loaded before the detail, and most sentences carry information. It is dense with internal references ('Phase 12 Wave 1 W1.1', 'INVARIANTS.md W1.6') that add little for a calling agent.

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?

There is no output schema, so the description properly carries the return-value burden by naming the 4 canonical license types and the tdm_reservation posture. The exact response envelope is left unspecified, but an agent has enough to call and interpret the result.

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 both parameters are already documented, giving a baseline of 3. The description elaborates on the jsonld flag's purpose (signed receipt, tdm:reservationSignedAt) but largely restates what the schema already carries.

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+resource ('Fetch a publisher's RSL Standard manifest via GET /rsl-manifest') and scopes the audience (AI agents/crawlers). It explicitly contrasts itself with the sibling article_53_attestation, so an agent can separate the two without inspecting either schema.

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?

Gives an explicit when-to-use ('BEFORE going through the buyer-account signup flow') and an explicit when-not ('It is NOT a signed compliance attestation (which is buyer-side, JWT-auth, via article_53_attestation tool)'). The routing is unambiguous.

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