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

Adds useful prerequisite context (PRO subscription and AI consent requirements) that annotations don't carry. However, with readOnlyHint=false it is unclear whether the drafted explanations are persisted, whether the CV is modified, or whether this consumes an add-on run; the description says nothing about those side effects.

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 tight sentences: the capability first, then the trigger condition and prerequisites. No filler or repetition of the name.

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?

There is no output schema, and the description does sufficiently characterize the return (draft explanations for CV and interviews). Minor gaps remain around what happens if no gaps are found and whether results are saved, but the essentials are covered.

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% and both parameters are fully documented in the schema, including the enum locale and where to get cvId. The description adds no parameter-level meaning beyond that, 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?

States a specific verb+resource pair: find gaps in a CV's work history and draft explanations for CV and interviews. This is clearly distinguishable from siblings like check_takemeup_resume_aging or find_takemeup_weak_achievements, which target different CV issues.

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 concrete trigger condition ('when the user has a break in employment they're worried about') plus prerequisites ('PRO and AI consent'), which is strong context. It stops short of naming alternatives or stating when not to use it, so not a 5.

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