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

Beyond the annotations, the description discloses the approval workflow, non-publication behavior, scheduling semantics, and content constraints. It also clarifies the permission needed for the separate publishing path. These details materially help an agent understand the behavioral consequences of calling the tool.

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 front-loaded and appropriately sized for a mutation tool with approval behavior and content rules. Most sentences carry relevant invocation guidance. The note about X charging more for posts with links is somewhat tangential and could be trimmed without losing actionable meaning.

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 the rich schema and annotations, the description covers the essential workflow: draft creation, pending approval, scheduling, and publishing alternative. It lacks some context around draft permissions and what the tool returns, but no output schema exists and the approval behavior is clearly explained. The multi-network scope is left mostly to the 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 coverage is 100%, so the parameters are already well documented. The description adds useful text-specific rules such as the 280-character X limit, link counting as 23 characters, no @mentions, and no invented facts. It does not add much to the network parameter beyond the schema, and its X-centric framing may obscure the other supported networks.

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 gives a specific verb and resource: propose/draft an X post for a Title, and it explicitly says the post is not published. It also distinguishes itself from publish_social_post. However, it frames the tool as an X-specific poster even though the schema supports telegram, bluesky, and discord, so the scope is slightly understated.

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?

It clearly describes the main usage context: creating a draft that lands in the dashboard for approval rather than publishing immediately. It names publish_social_post as the publishing alternative and includes the social:publish permission condition. It does not explicitly distinguish when to use draft_social_reply versus this tool, but the post-vs-reply distinction is reasonably implied by the resource name.

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