halt_release

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

With no annotations, the description carries the full burden. It discloses that the release will be marked as halted and users stop receiving updates, but does not mention reversibility, required permissions, or side effects.

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 concise, with two clear sections: a brief purpose statement and a structured Args/Returns list. Every sentence adds value and there is no fluff.

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?

Given three required parameters and no annotations, the description adequately covers the tool's purpose, parameters, and return value. It lacks some edge cases or prerequisites, but is sufficient for a straightforward action.

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 Args section adds meaning beyond the input schema by explaining each parameter's purpose (e.g., track contains internal, alpha, beta, production). Since schema coverage is 0%, the description compensates well.

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 tool halts a staged rollout, using specific verb and resource. It distinguishes itself from sibling tools like promote_release and update_rollout by specifying 'halt', but does not explicitly differentiate when to use alternatives.

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?

The description says to use it to stop a currently rolling out release, providing a clear scenario. However, it does not mention when not to use it or suggest alternative tools like promote_release or update_rollout for other actions.

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