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

Annotations already declare readOnlyHint=true, openWorldHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is known. The description adds no behavioral context beyond the verb 'Starts', such as whether the OAuth flow returns a redirect URL, requires a callback, or has side effects. It does not contradict annotations, but it also does not enrich them, leaving the agent without expectations for the flow.

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 a single, focused sentence with no filler. It is front-loaded with the essential action and resource, making it easy to parse. In terms of conciseness, it is exemplary; the issue is under-specification, not verbosity.

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 tool that initiates an OAuth flow, the description is incomplete. It does not indicate that the tool may return a URL for user authorization, that it requires a redirect URI, or that the flow typically involves subsequent steps. Even with annotations covering safety and schema covering parameters, the lack of behavioral context leaves an agent unsure of the invocation's outcome or next steps, especially given the absence of an output schema.

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%, so all parameters are already documented with basic descriptions (page, userId, reconnect, locationId). The description itself adds no additional meaning to the parameters, which is acceptable given the high schema coverage. Baseline 3 applies because the schema does the heavy lifting.

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 'Starts OAuth For Facebook Account' clearly states the verb (Starts) and resource (Facebook Account) and distinguishes it from sibling OAuth starters (e.g., Google, Instagram). However, it is terse and could benefit from mentioning the specific platform and that it initiates an authorization flow, but it is unambiguous in identifying the tool's core purpose.

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 guidance on when to use this tool versus the sibling 'social_media_posting_start_*_oauth' tools. It does not explain prerequisites, the need for user interaction, or conditions that would make this specific tool the right choice. The context (Facebook-specific) is implied but not explicitly stated as a selection criterion.

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