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

Annotations only say all hints are false, so the description carries the burden. It discloses asynchronous background execution, 5-10 minute wait, polling requirement, dedupe behavior returning the existing blog_id, and quota consumption. No contradiction with annotations.

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?

Compact and well-structured: action and async return first, then date/dedupe semantics, then quota impact. Every sentence carries operational value with no 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?

Covers the async lifecycle, polling target, dupe behavior, and plan limit. With no output schema, a minor gap is that for a non-dupe generation it doesn't explicitly state what the immediate response value contains beyond 'returns immediately.'

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%, but the description meaningfully expands scheduled_date (format, default, uniqueness per website/date) and keyword (target keyword). It does not explicitly explain the optional topic parameter, though the schema title and optionality make it low-risk.

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 + resource: 'Start generating an SEO article for a target keyword.' It also disambiguates itself from get_article_status by positioning this tool as the initiator of background generation rather than the status checker.

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?

Gives clear context: use this to kick off generation, then poll get_article_status until a blog appears. It also explains the one-article-per-website-per-date rule and the monthly limit, but does not explicitly contrast with siblings like publish_article or list_articles.

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