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

Annotations already declare destructiveHint=true and idempotentHint=true, so the base safety profile is known. The description adds 'Atomically,' which is a useful behavioral trait, but it does not explain what gets replaced or destroyed when publishing, or what state transitions occur.

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, front-loaded sentence with no filler. 'Atomically,' 'publish,' 'sealed,' and 'hosted graph version' each carry meaningful information.

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 a destructive, idempotent operation with seven parameters and no output schema, one sentence is insufficient. The description omits the sync workflow context, the concurrency purpose of expectedProjectVersion, idempotency semantics, and what happens after publication.

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% and there are 7 parameters, yet the description mentions none of them. It does not explain the roles of sealedManifestDigest, expectedProjectVersion, idempotencyKey, or the optional sessionId/executionId, leaving the agent to infer meaning solely from parameter names and patterns.

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 uses a specific verb, 'publish', with a specific resource, 'a sealed hosted graph version,' so an agent knows this finalizes a version. It is clear, but it does not explicitly distinguish this from the sibling publish_project_graph or place itself in the project_sync lifecycle.

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 guidance is given about when to call this tool versus alternatives such as seal_project_sync, abort_project_sync, or publish_project_graph. There is no mention of the required preceding sync/seal flow or when commit is appropriate.

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