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

Adds substantial behavior beyond annotations: link validity is 10 minutes, missing entitlement returns a reason and links instead of a file, opening the link consumes one PRO download once per link, and purchased CVs download without limit. These details are consistent with readOnlyHint=false and are important for correct invocation.

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?

Front-loads the core action and then adds only distinct operational constraints: TTL, entitlement fallback, and download accounting. It is dense but tightly structured with no wasted sentences.

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?

Covers the important edge cases an agent needs: entitlement requirements, fallback behavior, 10-minute link validity, and download counting. It does not specify the exact response object shape, but the key behavioral context is present and actionable.

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%, and the schema already documents cvId, the pdf/docx enum, locale enum, defaults, and cvId source. The description restates the available formats but adds no meaningful parameter semantics beyond 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 verb and resource: get a download link for one of the user's CVs as PDF or Word. It is clearly a download-link tool, but it does not explicitly distinguish itself from nearby siblings like get_takemeup_download_access or get_takemeup_cv_preview.

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 a clear use condition with 'Use when the user wants the file' and states entitlement prerequisites: one-time purchase for that CV or PRO. It does not name alternatives or explicitly say when not to use it instead of another sibling.

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