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

No annotations are provided, so the description carries the full behavioral burden. It usefully discloses a cost of 1 credit and that output is 'standalone' (self-contained), but says nothing about whether the HTML is returned inline or as a file, styling/CSS handling, size limits, or required permissions.

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?

A single front-loaded sentence identifies source, output, and purpose, with the cost parenthetical appended. There is no filler and nothing important is buried.

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 two-parameter, no-output-schema tool this covers the essential purpose, but it leaves open what the caller actually receives (HTML string vs file reference) and how markdown formatting maps to print styling. Adequate rather than complete.

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 nominally 100%, so the baseline is 3, but the schema descriptions are placeholders ('string', 'string, required') and the description adds no meaning about what `title` does or how it affects the printed document. It neither helps nor harms relative to the schema.

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 conversion (Markdown → print-ready standalone HTML) and names the intended end use (PDF printing), which implicitly distinguishes it from the make_docx/make_xlsx/make_csv siblings. It does not explicitly name an alternative, so it stops short of a 5.

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?

The phrase 'for PDF printing' implies the scenario in which this tool is the right pick, but there is no explicit when-to-use versus when-not or a named alternative for non-print outputs. Guidance is only implied.

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