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

No annotations are provided, so the description carries the behavioral burden. It discloses the default return (72h download short link) and the base64 fallback, which is useful. However it omits whether the operation is read-only/side-effect-free, permission requirements, and expected output characteristics beyond format.

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?

Information is front-loaded with the core purpose, but the sentence is dense and mixes purpose, output sheets, delivery modes, and prerequisites in one block. It is reasonably compact but not as structurally clean as it could be.

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?

Given the complex nested data schema and generated output, the description covers what the tool produces, delivery modes, and prerequisite tool calls. It is fairly complete, though it doesn't explain the division of labor with sibling Excel generators.

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 100%, so the schema already documents all three parameters in detail. The description repeats the return_mode behavior and file naming conventions but adds little syntax or format meaning beyond what the schema provides.

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 (pricing data JSON → full-formula Excel workbook) and even enumerates the sheets produced. This is clearly distinguishable from siblings like estimate_excel or fast_calc_excel, though the description does not explicitly contrast with them.

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 prerequisites (call get_protocol_instructions first; see get_skill_instructions for the five-step data collection) and states the default vs. recommended delivery mode. It does not name an alternative sibling for the same task, but the prerequisite routing is concrete.

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