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

With no annotations, the description carries the full behavioral burden and does reasonably well: it discloses that the operation is paid, that a Stripe Checkout URL is produced, that completion yields a PDF download, and that +10 bonus query credits are awarded. It omits auth/payment failure behavior, order durability, and whether the credit is granted before or after payment confirmation.

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?

Two sentences, zero filler, action and outcome front-loaded. Every clause carries information an agent needs (cost, checkout URL, deliverable, bonus credits).

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 payment/creation tool with no annotations and no output schema, the description adequately explains the input trigger and the resulting user-visible outcome. It could be more complete about required preconditions and failure modes, but nothing critical for correct invocation is absent.

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 all four parameters (email, barcode, doc_name, company_name) are already documented in the schema, including the cross-reference to get_company_filings for the barcode. The description adds no additional parameter meaning, so the baseline 3 applies.

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 ('Create a paid filing retrieval order for an official statutory document') and adds the concrete side effect of generating a Stripe Checkout URL. It does not explicitly differentiate itself from siblings like check_filing_order_status or get_company_filings, so an agent must infer the workflow split, but the core purpose is unmistakable.

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?

Usage is only implied: the description conveys that this is the order/payment step, but it never states when to use it versus check_filing_order_status or get_company_filings, nor does it give prerequisites (e.g., that a valid barcode must first come from get_company_filings). That prerequisite exists only in the schema's parameter description.

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