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

No annotations exist, so the description carries the full burden. It clearly discloses the 7-day expiration, claimUrl transfer mechanism, persistence with token, paid-plan restrictions on custom slugs and noindex, and the default visibility. This goes well beyond basic operation.

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 dense but efficient—three sentences covering core behavior, auth, expiration, and upgrade path. It front-loads the primary verb and result. Could be slightly more compact, but every sentence adds useful information.

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?

With 11 parameters, no output schema, and no annotations, the description must cover a lot. It covers authentication, persistence, paid plans, response structure (claimUrl), and parameter relationships. It doesn't fully describe all return fields, but the mention of claimUrl provides key output context. For a complex tool, this is strong coverage.

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 high (91%), so the baseline is 3. The description adds value by explaining the 'use this or files' relationship, auto-rename of a single root .html, and the paid-plan constraints on slug and noindex, which are not in the schema. It doesn't fully detail every parameter but compensates adequately.

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 action ('Publish HTML') and resource ('to a shareable https://<slug>.publee.site URL'), and distinguishes two modes: new publication vs. in-place update. This is exactly the desired specificity.

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?

Provides clear conditions for use: works without authentication, expires in 7 days, token persistence, custom slug requires paid plan on new sites, overwrite requires token. It doesn't name alternatives (no siblings exist) but does explain when to use the `html` vs `files` parameter. Minor deduction for not having an explicit 'when not to use' statement.

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