link_launches_to_release

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

The annotations already establish a non-read-only, idempotent, non-destructive mutation, so the description's added value is clarifying that launches are linked rather than copied. This gives the agent a meaningful model of what operation occurs without being deep about partial failures or return values.

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 sentences, front-loaded with the main action, and the second sentence earns its place by explaining the reference-as-copy distinction. There is no filler or repeated schema content.

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 mutation with two fully documented parameters and annotations covering idempotence and destructiveness, the description supplies the essential semantic distinction needed for correct invocation. Nothing import is missing.

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 100%, and the schema already explains both releaseId and launchIds, including where launchIds should come from. The description adds no parameter-specific detail, so it meets the baseline without needing to compensate.

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 states a specific verb and resource: 'Link launches to a release.' It further separates itself from Test Collections by explaining that launches are linked by reference rather than copied, so an agent can select this over related collection or copy workflows.

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 provides clear context that a reference link is being created, and explicitly contrasts this with Test Collection copy semantics. It does not explicitly name alternative tools or state 'when not to use', but the reference-versus-copy distinction is enough to guide tool selection.

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