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

With no annotations provided, the description carries the burden of behavioral disclosure. It reveals that analysis runs in parallel across 4 frameworks and lists the output categories (scores, dimension breakdowns, recommendations, cross-framework insights). This adds meaningful context beyond the schema, though it does not explicitly state side-effect-free behavior; analysis is inherently read-only, so the risk is low.

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 concise at 5 lines, uses a clear bulleted list for outputs, and front-loads the core function. Every sentence adds value: the parallel execution fact and the output summary are non-redundant. No fluff or repetition exists.

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?

Despite having an output schema, the description provides a helpful high-level summary of return structure, covering overall scores, dimension breakdowns, recommendations, and cross-framework insights. It also highlights the parallel execution aspect. It does not mention parameter-specific effects (e.g., platform affects scoring weights), but those are in the schema. The description is sufficiently complete for an agent to understand what the tool does and what it returns.

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%, so each parameter is already documented in the schema. The description does not add any extra meaning about the parameters—it does not mention platform or target_audience, leaving their roles entirely to the schema. This matches the baseline where the schema does 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 states a specific verb ('Analyze'), resource ('content'), and scope ('all 4 COS frameworks in parallel'). This clearly distinguishes it from sibling tools like analyze_framework, which likely target a single framework. The purpose is unambiguous and differentiates from alternatives.

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 clearly implies this is the comprehensive analysis tool ('using all 4 COS frameworks in parallel'), providing clear context that alternatives like analyze_framework are narrower. However, it does not explicitly state when not to use this tool or point to specific siblings, so it lacks overt exclusions or alternative routing.

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