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

No annotations are provided, so the description carries the full burden of behavioral disclosure. The description mentions the tool's purpose and usage context but lacks critical behavioral details: it doesn't specify what the analysis includes (e.g., features, pricing, strengths/weaknesses), whether it's read-only or has side effects, or any limitations (e.g., only covers listed competitors). For a tool with no annotation coverage, this is a significant gap.

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?

The description is extremely concise and front-loaded: two sentences that directly state purpose and usage guidelines with zero wasted words. Every sentence earns its place by providing essential information without redundancy.

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 tool's moderate complexity (competitive analysis with 2 parameters) and no annotations or output schema, the description is minimally adequate. It covers purpose and usage but lacks details on behavioral traits, output format, or limitations. Without annotations to fill gaps, the description should do more to be complete for an agent.

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%, with both parameters ('competitor' and 'context') well-documented in the schema. The description doesn't add any parameter-specific information beyond what's in the schema (e.g., it doesn't explain the 'other' enum option or provide examples for 'context'). Baseline 3 is appropriate since the schema handles the heavy lifting.

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?

The description clearly states the tool's purpose: 'Get a competitive analysis comparing Merlin against a specific competitor.' This specifies the verb ('Get'), resource ('competitive analysis'), and scope ('Merlin against a specific competitor'). However, it doesn't explicitly differentiate from sibling tools like 'handle_objection' or 'get_benchmarks', which might have overlapping competitive analysis functions.

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 description provides clear context for usage: 'Use when handling objections or competitive situations.' This gives practical guidance on when to invoke the tool. However, it doesn't explicitly state when NOT to use it or name alternatives among sibling tools (e.g., 'handle_objection' might be for general objections, while this is specifically for competitive comparisons).

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