abx_post_actions_by_id_action_runs

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

Annotations already declare readOnlyHint=false, idempotentHint=false and openWorldHint=true, so the fact that this mutates remote state is covered structurally. The description confirms execution occurs ('Runs the specified action taking into consideration the supplied configuration') and is consistent with those hints, but adds nothing beyond them - no mention of asynchronous behaviour, returned run identifier, or that runs can later be cancelled.

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 definition is short and front-loads the verb 'Trigger'. It wastes a little space by restating the same idea twice ('Trigger an action run' / 'Runs the specified action...') and by appending the HTTP path, which the annotations title already carries.

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 trigger tool with a large nested body object and no output schema, the description should say what comes back (a run id? a run object?) and whether the call blocks or is asynchronous - both are completely absent. With no output schema to compensate, an agent cannot tell how to obtain or track the run it just started.

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 reported at 100%, and both top-level parameters carry descriptions ('ID of the action (path)', 'Configuration of the action run'), so the baseline of 3 applies. The phrase 'taking into consideration the supplied configuration' adds no actionable meaning - it does not say which of the ~20 nested body properties (inputs, runtime, timeoutSeconds, actionId) are actually honoured versus echoed.

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 gives a specific verb and resource: 'Trigger an action run' against /actions/{id}/action-runs, which is concrete enough for an agent to know this launches an action execution. However it never distinguishes this tool from the close sibling abx_post_action_runs, which appears to do the same thing via a different path, so the agent has no basis for choosing between them.

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?

There is no when-to-use guidance at all: nothing explains when to pick this over abx_post_action_runs, or that abx_cancel_action_run and abx_get_action_run_by_id are the follow-on tools for an in-flight run. The only hint of usage is implied by the verb 'Trigger'.

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