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

Goes beyond the annotations by describing the actual side effects: pages, feed and sitemap are regenerated, non-draft posts become public at their address, and removed or unpublished posts disappear. "Changes are public immediately" adds an important visibility caveat not in the structured fields. Not a contradiction with destructiveHint=false — this is regeneration, not data deletion — though noting that it only affects the public surface, not stored content, would complete it.

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?

Two tight sentences, front-loaded with the verb and outcome, then the immediate-public consequence. No filler or repetition of the title.

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?

For a one-parameter publish tool with annotations declaring non-destructive, idempotent and closed-world behavior, this covers what actually happens to the site and its public output. No output schema exists so return values needn't be explained; only a hint about ordering relative to post-writing tools is missing.

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% and the single parameter (site) is documented as "The site name." The description adds no syntax, format, or naming guidance beyond that, so it neither compensates nor detracts — the baseline 3 applies.

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 and resource ("Publishes a Pagehaus site's blog") and then spells out the concrete mechanics — pages, feed and sitemap are rewritten from posts. That distinguishes it clearly from content-authoring siblings like write_post and delete_post without needing their schemas.

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?

Usage is only implied: the description makes clear the tool materializes the post list into public output, so an agent can infer it belongs after post edits. It never states when to call it versus alternatives or whether it must follow write_post/delete_post, and offers no exclusions.

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