ghl_saas_allow_attach_rebilling

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

Discloses state-changing behavior (sets payment_pending, optionally stores config) and preconditions. No contradiction with annotations (readOnlyHint=false, destructiveHint=false). Adds context beyond annotations.

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?

Well-structured with key information front-loaded: auth requirement, action, preconditions, and endpoint. Minor redundancy with title repeated, but overall efficient.

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?

Covers security, precondition, action, and endpoint, but lacks return value or error information. No output schema, so description could better specify expected outcomes.

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% with descriptions for all parameters. Description provides overall context but does not significantly add new semantic meaning beyond what the schema already explains.

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?

Clearly states the tool marks a SaaS sub-account as awaiting rebilling attach and optionally stores rebilling configuration. Distinguishes from sibling tools by being specific to this action, though not explicitly contrasted with similar tools like ghl_saas_update_rebilling.

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?

Provides a precondition (sub-account must be in setup_pending state) and authentication requirement (agency-level token). However, lacks guidance on when not to use this tool or alternatives to consider.

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