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

Annotations already declare readOnlyHint=false and openWorldHint=true, and the description adds real behavioral context beyond them: that the article becomes publicly live on the user's site and that user confirmation is required beforehand. It does not address reversibility, retry/idempotency behavior, or failure modes, which keeps it out of 5 territory.

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 short sentences, zero filler, with the action and the safety instruction front-loaded in order of importance. Every sentence carries information the agent needs.

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 write tool with five fully undocumented required parameters and no output schema, the description does not supply enough to invoke it correctly — idempotency semantics, what a 'connection' is, and how failures surface are all unaddressed. Annotations cover the safety profile but not the invocation contract.

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% across five required parameters, so the schema provides no meaning at all. The description only obliquely maps 'article' to assetId and 'connected CMS' to connectionId; projectId, siteId, and especially idempotencyKey are left entirely unexplained despite being required.

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 an approved article') and names the destination ('a connected CMS'), which is enough to separate it from generate_article or update_article. It does not explicitly name the adjacent stage tools (submit_article_for_review, verify_article_publication), so differentiation is implied rather than stated.

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 words 'approved article' imply a prerequisite state and 'confirm with the user first' gives a conditional instruction, so usage is partially implied. However, it never contrasts against the obvious alternatives in the review/verification pipeline, nor says what to do if the article is not yet approved.

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