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

Annotations already declare destructiveHint=true, and the description is consistent with that, adding that it runs the deployment script and returns the created deployment object. However, it does not disclose whether the deployment is asynchronous, whether concurrent deploys are rejected, or what permissions are required - gaps that matter for a destructive trigger.

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?

Three short sentences, front-loaded with a warning marker and the core action, then the return behavior, then the API endpoint. The endpoint line is mildly extraneous but cheap and aids orientation; nothing is buried.

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?

Return behavior is stated, which compensates for the absent output schema, and params are fully covered by the schema. It stops short of telling the agent how to track the deployment afterwards (forge_get_deployment_status / forge_get_deployment_log) or noting asynchronous completion, which are the remaining gaps for a destructive trigger tool.

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% (all three required ids documented in-schema), so the baseline is 3. The description's REST path template reiterates organization/server/site as path parameters but adds no format, id-source, or validation detail beyond the schema.

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 precise verb and resource: 'Triggers a new deployment of the site', clarified parenthetically as running the deployment script. That distinguishes it cleanly from the get_/list_ siblings, though it never names the one adjacent mutating sibling (forge_run_site_command) 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?

Usage is implied by the purpose (call it when you want a new deployment) but there is no explicit when-to-use guidance, no statement of prerequisites, and no comparison against forge_run_site_command or the status/deployment-reading siblings. An agent can infer the intent but gets no routing help.

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