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

Annotations declare destructiveHint=true and openWorldHint=true, and the description adds valuable behavioral context: a user confirmation step occurs first, the latest saved version is published, and progress is shown. It doesn't explain what makes this destructive or whether re-publishing overwrites, but adds real process detail beyond the 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?

Two sentences, front-loaded with the trigger condition, no wasted words. The sequencing (confirm, then publish, then progress) is clearly ordered.

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?

Output schema exists so return values needn't be explained. Description covers trigger, confirmation flow, and what gets published, which is sufficient for a state-changing tool with destructive/openWorld annotations. Minor gap: no mention of failure modes or prerequisites like domain setup.

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 50%. The confirm parameter is well documented in the schema (card-only, agent should leave it out), and the description implies the confirmation flow. But site_id has no description in schema or description. Baseline 3 given the schema covers the tricky parameter.

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 (publish the user's site live) and distinguishes itself clearly from siblings like unpublish-site and show-preview. An agent immediately knows this makes a site publicly live.

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?

Clear trigger context: 'when the user wants their WebTwizz site live on the web.' It doesn't explicitly name unpublish-site as the inverse or discuss preview vs publish, but the usage condition is well stated.

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