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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false, and openWorldHint, so the safety profile is covered. The description adds one genuinely useful behavior not in the annotations: a required read scope (an auth prerequisite). It says nothing about pagination, sorting, result volume, or what 'release state' means for the caller.

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?

Two short sentences with no filler, and the resource is stated first followed by the access prerequisite. It is close to optimally sized, though the first sentence subordinates the actual action to a noun phrase.

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?

A parameterless read is simple, but there is no output schema, so the description is the only place an agent can learn what comes back. 'Including reports and release state' gestures at the payload without explaining its structure or whether the list is scoped to the calling user ('Owned').

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?

The tool takes zero parameters and the schema has full coverage, so there is no parameter meaning to add. The description appropriately avoids inventing filtering options that do not exist.

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 names the resource ('Owned experiment jobs') and hints at returned content ('reports and release state'), but never supplies a verb such as list or retrieve, so the agent must infer that this is a collection read. It also does not distinguish itself from the singular sibling emt_experiment_job, which is the main ambiguity an agent would face.

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 or when-not-to-use guidance. With a near-identical sibling name (emt_experiment_job) present, the description should say it returns all jobs versus a single job, or whether a narrower sibling such as emt_monitor should be preferred for live status; it says none of this.

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