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

Annotations indicate destructiveHint=true, aligning with the description's 'publishes' action. The description adds valuable context beyond annotations: it explains routing per content type, the need for an Email MCP connection for newsletters, and an outbound-tier approval note (first use may require manager approval). However, it doesn't detail the exact side effects or the approval flow's behavior in depth, but the disclosure is strong for a mutation 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 thorough but somewhat long, with a dense routing section and a bracketed note that may be tangential. The critical usage guideline is stated early, but the social post exclusion is placed mid-paragraph and could be more prominent. The warning about approval is important and included, but the overall structure could be tightened.

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?

The description covers the tool's purpose, usage conditions, exclusions, and behavioral nuances, which is comprehensive for a 3-parameter tool. It explains the routing logic, the email connection requirement, and the approval note, making it nearly complete. The lack of an output schema is fine since the action is a publish operation. Minor gaps: no explicit statement about reversal or idempotency, but annotations already indicate non-idempotent and destructive.

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 100%, so the schema already documents each parameter. The description adds context for item_id (must be approved), companyId (membership requirement), and recipients (default behavior: sends to all team members), which enriches the schema descriptions. However, it duplicates some schema info, but the added routing and default behavior justify a score above baseline.

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 ('Publish') and resource ('approved INTERNAL content to configured output'), and clearly differentiates from sibling tools like submit_content_to_pipeline by excluding social posts. It also lists the content types it handles (changelog, team update, report, newsletter), making its scope unambiguous.

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 description explicitly says when to use this tool ('Use when an approved non-social item... is ready to send') and when not to use it, with a dedicated section on social posts that routes to submit_content_to_pipeline and update_pipeline. It also mentions the required approval status, eliminating ambiguity.

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