nws_public_witnessing_commit_assignment

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

With no annotations, the description carries the full burden; it does disclose one meaningful behavioral trait — the commit is conditional on underlying NWS data not having changed. It omits conflict/error behavior, whether the commit is reversible, and any permission or side-effect (e.g., notifications to publishers) information, which matters for a mutation tool.

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?

A single front-loaded sentence with zero waste; the condition is stated compactly after the core action.

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?

An output schema exists, so return values need not be explained. But for a mutation tool with no annotations and an undocumented confirmation_id, the description should at minimum explain the provenance and lifecycle of the confirmation token and the consequence of a stale-data conflict; it does neither.

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% for the single required parameter, confirmation_id. The description only hints it is tied to a prior preview ('previewed shift assignment') but never states where confirmation_id comes from, its format, or how long it is valid, so it does not compensate for the schema gap.

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?

States a specific verb (commit) and a specific resource (one previewed shift assignment), plus a scoping condition that NWS data must be unchanged. This distinguishes it from the sibling preview_assignment and cancel_assignment, though it does not name those siblings explicitly.

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 word 'previewed' implies this must follow nws_public_witnessing_preview_assignment, and the 'if NWS data is unchanged' clause implies a conditional/concurrency guard. However, the description never states what to do on conflict, whether to re-preview, or how the tool relates to its cancel counterpart, leaving the workflow only implied.

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