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

With no annotations, the description carries the full burden and does disclose meaningful traits: it is 'Not a credit debit', 'Nothing is published' (limited side effects), and 'Writer failure is named — never an outline template' (failure behavior). Auth requirements are also stated. It still omits return format and any rate/limit behavior, keeping it below a 5.

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 main purpose is front-loaded and each clause tries to carry information, so it is not padded. But the prose is a dense run of fragments and shorthand ('length=short|medium|long.', 'Same writer door', 'stays cognition') that sacrifices parseability for compression, hurting structure relative to its length.

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 zero-annotation, zero-required-param, 12-parameter tool with no output schema, the description supplies useful auth and side-effect context. Still, with no output schema and very low parameter coverage, several inputs (url, topic, next_step, payment ids) and the response shape are left unexplained, so it is not fully complete for the tool's complexity.

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 only 8%, so the description must compensate, and it does explain several key params: unlock_token source, who, proof or proof_mode=no_proof, length values, and the piece_kind enum plus its cognition effect. But it leaves url, topic, next_step, paymentId/payment_id, and unlockToken undocumented, so half the 12 params remain unexplained.

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 opening line names a concrete verb+resource (a paid page draft produced after a settled page_draft_long checkout or via a developer key), which is specific. However, the meaning is buried in internal jargon ('writer door', 'cognition', 'Same writer door as the web buyer') that an outside agent cannot decode. It does not explicitly contrast itself with the sibling launchfiles_standalone_page_draft_short.

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 states a precondition (a settled checkout or a developer key) and how to authenticate (unlock_token from the billing poll, or Authorization: Bearer with the developer key). That is real usage context, but there is no explicit when-not-to-use rule or a named alternative such as the free short draft sibling. Usage is implied rather than routed.

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