Croncool Cron Jobs

Run a cron job now

run_job

Destructive

Use this when the user wants to immediately execute the configured request for one CronCool job. Returns only that Croncool invoked it, not the target's response. Each call immediately sends the job's configured request again, which can write, message or bill downstream, and a repeated call sends it once more. Not for checking a run's result.

A4.4/5.0

Behavior5/5

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

Beyond the annotations (destructive, non-idempotent, open-world), the description explains the mechanism: each call re-sends the job's configured request, which 'can write, message or bill downstream,' and a repeat call sends it once more. It also discloses the return contract (only an invocation acknowledgement, not the target's response), information neither the annotations nor the output schema convey as clearly.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Four sentences, front-loaded with the trigger condition and followed by the return contract and the side-effect warning; every sentence carries distinct information. Minor awkwardness in the second sentence slightly reduces polish but not substance.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a one-parameter action tool, the description covers the trigger, the non-obvious side effects, the non-idempotent behavior, and the narrow return value. Nothing an agent needs to call it correctly or interpret its result is missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% and the single jobId parameter is fully documented in the schema as a uuid. The description adds no further parameter-level detail, so the baseline of 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb and resource: 'immediately execute the configured request for one CronCool job.' It is unambiguously distinct from read siblings like get_job_runs because it defines the target action (send the configured request) rather than observing runs.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It clearly states when to use it ('when the user wants to immediately execute...') and adds an explicit exclusion ('Not for checking a run's result'), which routes the agent away from run-inspection siblings. It stops short of naming the alternative tool, so it falls just short of a 5.

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