generate_dev_report

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the agent knows this is a safe read operation. The description adds useful context about the DevMemory (데브메모리) source and the daily/weekly format, but does not disclose output details or limitations.

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 a single concise sentence that front-loads the verb and resource. It avoids fluff and provides essential information without unnecessary detail.

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?

With no output schema, the description should explain what the report looks like or how it is returned. It also lacks guidance on parameter selection for different environments (repoUrl vs repoPath), which is a significant gap given the tool has 5 parameters.

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 80% (4 of 5 params have descriptions), so the schema already provides most parameter meaning. The description adds 'daily/weekly' which aligns with the format enum, but does not explain the distinction between repoUrl and repoPath or provide example usage.

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 a specific verb ('Generates') and resource ('dev report'), and specifies the data source ('commits and diffs'). This distinguishes it from sibling tools like get_commit_timeline or summarize_commit, which focus on individual commits or timelines.

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?

There is no explicit guidance on when to use this tool versus alternatives like get_commit_timeline or summarize_commit. The description does not mention prerequisites (e.g., having a git repo) or scenarios where a simpler tool might be more appropriate.

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