Blog: Publish post

blog_publish_post
Destructive

Publish a blog post on its site now, or schedule it for a future moment ('publish_at', ISO-8601 with timezone). The post becomes visible to site visitors at that moment. Reversible from the cabinet (unpublish). Runs propose→confirm. CONFIRMATION: this tool is PROPOSED, never performed directly. You get status='confirmation_required' with an action_id and a plan_token, and the write happens only after confirm_action.

A4.3/5.0
Behavior5/5

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

Beyond the annotations, the description discloses the key workflow: the tool only proposes the action, returns status='confirmation_required' with action_id and plan_token, and performs the write only after confirm_action. It also adds important behavioral context about visitor visibility and reversibility via unpublish.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is appropriately sized and front-loads the core publish-or-schedule behavior. The confirmation workflow is clearly stated, though 'Runs propose→confirm' and the longer CONFIRMATION segment partially repeat the same idea.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a write tool with a propose→confirm safety workflow, the description covers the most important behavior an agent needs: scheduling semantics, visibility, reversibility, and confirmation mechanics. It is somewhat less complete on parameter meaning for 'post_id' and on error or edge-case behavior.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema documents 'publish_at' as ISO-8601 and optional, but not 'post_id'. The description adds that 'publish_at' includes timezone and controls immediate versus scheduled publishing, but it does not explain 'post_id', leaving the 50% schema coverage gap only partially compensated.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb and resource: publish a blog post on its site. It clearly distinguishes publishing now from scheduling for a future moment via 'publish_at'.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It explains the primary usage choice: publish now, or schedule later by supplying 'publish_at'. It also explains that the action is reversible via unpublish and that it requires a propose→confirm flow, though it does not explicitly compare against siblings such as blog_update_post or blog_create_draft.

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