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

With no annotations provided, the description carries the full burden of behavioral disclosure. It mentions the tool 'supports' various operations but doesn't describe behavioral traits like whether operations are read-only or destructive, permission requirements, error handling, or rate limits. For example, it doesn't clarify that 'delete' is destructive or that 'create' might require specific Git permissions. This leaves significant gaps for an agent to understand the tool's behavior.

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 appropriately concise with two sentences that efficiently state the tool's purpose and scope. It's front-loaded with the core functionality and avoids unnecessary details. However, it could be slightly more structured by explicitly listing the actions or separating local vs. remote operations for better clarity.

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?

Given the tool's complexity (14 parameters, multiple actions) and lack of annotations and output schema, the description is incomplete. It doesn't address key contextual aspects like the distinction between local and remote operations (implied by parameters like 'owner' and 'provider'), the interaction between parameters (e.g., 'annotated' vs. 'lightweight'), or what the tool returns. For a multi-action tool with no structured behavioral hints, more comprehensive guidance is needed.

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?

The description adds minimal parameter semantics beyond the input schema, which has 100% coverage. It mentions support for 'both lightweight and annotated tags,' which relates to the 'annotated' and 'lightweight' parameters, but doesn't explain their interaction or default behavior. Since schema coverage is high, the baseline is 3, and the description provides only marginal additional context about tag types without detailing parameter usage or constraints.

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 the tool's purpose as 'Git tag management tool for tag operations' and specifies the supported operations (create, list, get, delete, search) and tag types (lightweight and annotated). It distinguishes this tool from siblings by focusing specifically on tags rather than other Git operations like branches, issues, or pulls. However, it doesn't explicitly differentiate from all siblings (e.g., git-release might overlap with 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?

The description provides no guidance on when to use this tool versus alternatives. It doesn't mention when to choose this tool over other Git tools in the sibling list (like git-release for release-related tags) or when to use specific actions within the tool. There's no context about prerequisites, typical use cases, or exclusions.

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