create_tag

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

The description discloses that the tool fetches the latest commit SHA internally and logs errors on failure. However, it does not specify the type of tag (lightweight vs annotated) or side effects like triggering CI events. With no annotations, the description partially covers behavioral traits but not comprehensively.

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 separate sections for Args, Returns, and Error Handling. It is not overly verbose, though the Error Handling section could be slightly more concise. The main purpose is front-loaded.

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?

The description covers the basic flow: parameters, return values, and error handling. However, it lacks context on prerequisites (e.g., repository existence, commit availability) and idempotency. Given the tool's complexity and no annotations, it is adequate but not fully comprehensive.

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?

Input schema has 0% description coverage, and the description provides brief explanations for each parameter (e.g., 'repo_owner: The owner of the repository'). This adds basic meaning but lacks format constraints or examples. Baseline compensation for low coverage is partially met.

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 it creates a new tag in a GitHub repository. The verb 'creates' and resource 'tag' are specific, and it distinguishes from sibling tools like create_issue or create_pr by focusing on tag creation.

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?

No explicit guidance on when to use this tool versus alternatives. It does not specify prerequisites like requiring an existing commit or mention that it creates an annotated tag (requires message). Lacks usage context and exclusions.

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