enable_environment_connection

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

Annotations already declare mutation (readOnlyHint=false), no external side effects, idempotency, and non-destructiveness. The description adds a genuinely new operational fact not in the annotations: 'Requires the caller OAuth token.' Its idempotency sentence merely restates idempotentHint=true, so it does not fully earn a 5.

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?

Front-loads the action, then follows with acquisition step, exclusions, auth requirement, and idempotency in five tight sentences with no filler.

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 two-parameter toggle with no output schema, the description covers prerequisites, auth, idempotency, and boundary exclusions. An agent has everything needed to call it correctly and interpret the result.

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 coverage is 100% and both parameters carry format patterns (conn_<id>, env_<id>), so the schema does the heavy lifting. The description adds only the pointer to list_environment_connections for obtaining connection_id, which is helpful but already captured as usage guidance rather than parameter semantics.

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?

States a specific verb (Enable) plus a precisely scoped resource (one existing environment connection). It immediately distinguishes itself from create_environment_role/create_organization and from list_environment_connections, so an agent can identify what it does without opening the schema.

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?

Gives explicit positive workflow ('Use list_environment_connections to find the connection id') and two explicit exclusions ('does not create a connection', 'does not enable an organization connection'). This is exactly the when/when-not/alternative pattern.

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