trigger-synthetics

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

No annotations provided, so the description must carry the behavioral burden. It only says 'Trigger one or more Synthetics tests on demand', but fails to disclose what happens when tests are triggered (e.g., immediate execution, queuing, rate limits, impact on existing tests, or concurrency constraints). This is insufficient for a trigger action.

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 sentence, which is concise and front-loaded. However, it could be slightly more informative without losing conciseness (e.g., mentioning that the tests must exist).

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 simple trigger tool with one parameter and no output schema, the description is partially adequate. It covers the basic purpose, but lacks details on prerequisites, side effects, and how to interpret the trigger (e.g., async vs sync). The agent may need to guess these aspects.

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 coverage is 100% with only one parameter 'tests' (array of objects with 'publicId'). The description does not add any extra meaning beyond what the schema already provides. It does not explain the purpose of publicId or mention that the tests must be pre-existing. Baseline 3 is appropriate.

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 action ('Trigger') and the resource ('Synthetics tests'), with the qualifier 'on demand'. It distinguishes itself from sibling tools like create-synthetics-test (which creates tests) and get-synthetics-result (which fetches results).

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 on when to use this tool versus alternatives. It does not mention prerequisites, limitations, or cases where other tools (e.g., get-synthetics-test, create-synthetics-test) would be more appropriate. The phrase 'on demand' is generic.

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