update_release_tag

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

No annotations are provided, so the description must carry the behavioral transparency burden. It discloses key behavior: partial update semantics ('Only the fields you pass are changed') and the return value (the updated ReleaseTag). However, it does not clarify null-handling behavior (e.g., whether passing null clears a field), error conditions, or potential side effects, leaving some ambiguity for a behavioral safety assessment.

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 concise and well-structured: a single-sentence purpose, a clear Args list, and a Returns line. Every sentence contributes value, and the format is easy to scan. No redundancy or fluff.

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?

For a simple CRUD update tool, the description covers the essential aspects: what it updates, which fields are updatable, and what is returned. Given that an output schema exists, return values do not need further explanation. The only notable gap is the ambiguous handling of null values for optional fields, which could affect usage in partial-update edge cases.

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. It does so effectively with an Args section explaining each parameter: tag_id (UUID), version (with example), description (notes), commit_hash (Git commit source), and git_tag (corresponding tag name). This adds semantic meaning beyond the bare schema types, though it could be more explicit about null behavior and valid formats.

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 states a specific verb and resource: 'Update a release tag by ID.' It clearly distinguishes this from sibling tools like create_release_tag, retrieve_release_tag, and delete_release_tag by focusing on the update operation. The partial-update clarification ('Only the fields you pass are changed') further sharpens the purpose.

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 makes clear this tool is for updating an existing release tag by ID. It implies a partial-update usage pattern, but does not explicitly state when not to use it or contrast with alternatives like update_release. The context is unambiguous enough for a developer to know when to invoke it, but it lacks explicit exclusions.

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