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

Adds real behavior beyond the annotations: the draft is non-publishing (awaits approval), it overwrites any earlier unpublished suggestion for the same item, and content is constrained (no links, no @mentions because X adds the author). Those are exactly the side-effect and content rules an agent needs before calling a non-readOnly 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?

Three short sentences, front-loaded with the action and provenance, then the approval/overwrite behavior, then the content rules. Nothing is repeated from the schema and no sentence is filler.

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?

With no output schema, the description still covers the important post-call state (draft pending approval, prior suggestion replaced) and content constraints. The only gap is what happens on an invalid or already-published item_id, which an agent would want to know.

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 baseline is 3, but the description adds meaning for text (link and @mention prohibition) and for item_id (retrieve it from get_social_inbox). title_id is left as the bare 'TitleID' label, which is the only unexplained input.

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?

States a specific verb (propose a reply) and resource (an inbox item), and pins the item_id's provenance to get_social_inbox. The 'waits for approval in the dashboard' clause cleanly separates it from publish_social_reply and from draft_social_post, which targets posts rather than inbox items.

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?

Explicitly tells the agent where item_id comes from (get_social_inbox) and that the result is queued for dashboard approval rather than published immediately, which is the key routing signal versus publish_social_reply. It does not spell out exclusions or failure conditions, so it stops short of a 5.

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