Update GitOps sync

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

Annotations already indicate idempotentHint=true, so the description does not need to repeat that. However, the description adds no additional behavioral context such as which fields are optional or whether the update partially replaces the configuration. It is adequate but does not enrich beyond the structured data.

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 efficiently states the tool's purpose. While it is minimal, it avoids redundancy. A slightly more informative phrase (e.g., listing common updateable fields) would be more helpful, but it is not verbose.

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 has 8 parameters and no output schema or return value explanation, the description is too sparse. It does not mention that only optional fields are updated or that the required parameters identify the sync. This lack of context could lead to misuse or incomplete invocations.

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 100%, so the baseline is 3. The description adds no parameter-specific meaning; it simply reiterates the tool's action. The schema itself already describes each parameter sufficiently.

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 verb 'Update' and the resource 'GitOps sync configuration', making the tool's purpose immediately understandable. However, it does not differentiate from sibling tools like arcane_gitops_create or arcane_gitops_delete, which also target GitOps sync configurations.

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 usage guidelines are provided. The description does not indicate when to use this tool over alternatives such as arcane_gitops_create (to create a new sync) or arcane_gitops_sync (to trigger a sync). There is no mention of prerequisites or expected context.

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