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

With no annotations provided, the description carries full burden and exceeds expectations. It details side effects (read-only, no external modification), authentication (none for basic, api_key for higher tiers), rate limits (10/day free, unlimited pro), error handling (structured errors), idempotency (fully idempotent), and data privacy (no storage). No contradictions with annotations since none exist.

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 well-structured with clear sections, but contains redundant content. The 'Behavior:' and 'Behavioral Transparency:' sections overlap significantly, and the 'Args' section is repetitive. It could be trimmed by merging the behavioral sections and removing the generic 'Args' descriptions, which add no value.

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?

While behavioral transparency is thorough, parameter semantics are weak. The output schema exists but the description does not explain the return format (e.g., plain markdown, structured object). Given the tool's purpose, the description is moderately complete but lacks clarity on what the output looks like and how parameters shape it.

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 0%, so the description must compensate. The 'Args' section only repeats parameter names and types, adding generic phrases like 'The ... to analyze or process.' This adds no meaningful context beyond the schema. For example, 'project_name' is not explained as the name of the project for which the README is generated. This is a significant gap.

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 'Generate a complete README.md from project metadata including sections for install, usage, API, and contributing.' This is a specific verb+resource combination that distinguishes it from sibling tools like analyze_project, generate_badges, and suggest_sections, which focus on analysis or partial generation.

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 includes explicit 'When to use' and 'When NOT to use' sections. It advises using the tool for structured analysis or classification against standards, and warns against real-time production decision-making without review. However, it does not directly compare to siblings, leaving some ambiguity about when to choose this over alternatives.

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