Validate Edit

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

With no annotations, the description carries the behavioral burden and does well: it discloses that the edit is discarded, that nothing is committed, and that a failure indicates the service account cannot publish. It does not mention auth or rate limits, but for a dry-run safety profile this is adequate.

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 compact and front-loaded: the first sentence captures the core dry-run behavior, and the following sentences add no-commit semantics and a concrete use case. Every sentence earns its place with no filler.

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 one-parameter tool with an output schema, the description explains the edit lifecycle, the no-commit behavior, and the primary intended use. It is not exhaustive about alternatives like validate_open_edit, but nothing essential to calling it correctly is missing.

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 schema description coverage is 100% for the single package_name parameter, so the baseline is 3. The description adds no material parameter-level detail beyond what the schema already provides.

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 operation: dry-run an edit by opening, validating, and discarding it, and it clearly distinguishes itself from commit/deploy operations by emphasizing that nothing is committed. However, it does not explicitly differentiate from the near-named sibling 'validate_open_edit', which weakens sibling differentiation.

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?

It gives clear usage context: most useful as a permissions probe before a deploy, and it explains the benefit of learning about publish failures before release. It does not name alternatives or say when not to use it, but the implied lifecycle is clear.

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