git_work_report

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

Discloses core behaviors: reading git commits, running git show, AI analysis of diffs, and output formatting. Annotations confirm readOnly and idempotent nature, which matches the description. No contradictions.

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?

Well-structured with clear sections (core function, output format, usage examples). Every sentence adds useful information without redundancy. Front-loaded with purpose.

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?

Although no output schema, the description fully specifies the output format (bullet points, Chinese, professional style, excluded elements). Parameters are fully covered. The tool's complexity is well addressed.

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?

All parameters are described in the schema (100% coverage). The description adds value by explaining the difference between date (daily mode) and start_date/end_date (periodic mode), and notes output_file is optional.

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?

Clearly states the tool generates work reports from Git diff analysis, supports daily and periodic modes, and provides concrete examples. Distinguishes from sibling tools by specifying a unique function.

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?

Provides explicit usage modes (daily vs periodic) with parameter examples. Does not explicitly mention when to avoid using, but the context of sibling tools makes it clear.

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