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

The description adds substantial context beyond the annotations: the copy is public, confirmation is required, it can be moved or cancelled before publication, and it does not evaluate original performance. It also discloses failure conditions around approval requirements and an empty posting queue, which is valuable for a destructive, non-read-only action.

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 action is front-loaded in the first clause, and every subsequent sentence adds practical information about confirmation, reversibility, source-post selection, or failure modes. There is no redundant restatement of the name or annotations.

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?

Although there is no output schema, the description states what is returned: the new post and its scheduledFor value. It also covers confirmation requirements, ID selection pitfalls, reversibility, and failure conditions, leaving no major gap for an agent invoking this tool.

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 already 100%, so the baseline is 3. The description still adds useful semantic guidance by warning that postId must be the Ignix id from list_posts, not the analytics id returned by get_top_posts.

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 uses a specific verb and resource: schedule a copy of an existing post in the next free queue slot. It also states the return values and a key behavioral limitation, namely that it does not check how the original post performed.

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 gives clear pre-use guidance, especially confirming with the user before public posting, and names update_post and unschedule_post for moving or cancelling the copy before it goes out. It also explains how to find a good source post via get_top_posts and list_posts, though it does not directly compare recycle_post to siblings such as duplicate_post or schedule_post.

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