publish_page_photo

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only says the tool publishes a photo; it does not mention permissions, side effects on the Page timeline, draft behavior when 'published' is false, or any other operational consequences.

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 front-loaded sentence with no filler and no redundant restatement of the schema. Every word contributes to understanding what the tool does.

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 publish action with an output schema and mostly self-explanatory parameters, the description covers the core operation. However, it omits usage boundaries and behavioral context that would help an agent confidently choose and invoke it, especially given no annotations.

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 0%, so the description must compensate for missing parameter documentation. It clarifies that 'image_url' should be a public URL, but it does not help with 'page_id', 'caption', or 'published' beyond the bare schema titles and defaults.

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 ('Publie'), resource ('une photo sur une Page Facebook'), and source ('depuis une URL publique'). This clearly differentiates it from siblings like publish_page_photo_from_file and publish_page_post.

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 phrase 'depuis une URL publique' implies this tool is for publishing an image accessible via URL, which distinguishes it from file-based siblings, but the description does not explicitly state when to use it vs alternatives or mention exclusions. Usage context is implied, not stated.

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