  5/5.0
  Behavior5/5

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

  Despite no annotations, the description fully discloses behavior: it loads a profile to make the agent act like the user, returns profile text or a recovery instruction, and explains domain semantics. No hidden side effects or contradictions.

  Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

  Conciseness5/5

  Is the description appropriately sized, front-loaded, and free of redundancy?

  Two sentences with no filler. The first sentence covers purpose and timing, the second covers domain definitions and return value. Efficiently communicates all necessary information.

  Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

  Completeness5/5

  Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

  Given the simple input schema and no output schema, the description covers purpose, usage guidance, parameter semantics, and return value. No gaps remain for effective agent invocation.

  Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

  Parameters5/5

  Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

  The single parameter 'domain' has 100% schema coverage with an enum and description. The description adds rich meaning by explaining what each domain represents (execution, debugging, UI/UX, writing voice), far exceeding the schema's minimal description.

  Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

  Purpose5/5

  Does the description clearly state what the tool does and how it differs from similar tools?

  The description clearly states the tool loads the user's Ditto profile to mimic them, specifies when to call it, and explains the domains with concrete examples. It distinctly identifies the tool's purpose and resource.

  Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

  Usage Guidelines5/5

  Does the description explain when to use this tool, when not to, or what alternatives exist?

  Explicitly instructs to 'Call this before working on their task', and details the three domains and their coverage (work, design, write). This provides clear guidance on when and how to use the tool.

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