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

Annotations already cover the safety profile (readOnly, idempotent, non-destructive, closed-world), and the description adds genuinely new context: the data is a frozen saved receipt, that requested raw-field changes are distinguished from independent provider readback, and that no credits are consumed. The only weakness is that the frozen/staleness implication is stated in compressed jargon rather than plainly.

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?

It is short and reasonably front-loaded, but the middle sentence ("Saved receipt distinguishes requested raw-field changes from independent provider readback") is dense and unclear, and the closing "No provider write or new credits" partly restates the readOnly annotation. Two of the three sentences carry real information; the phrasing wastes space on ambiguity rather than excess length.

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?

An output schema exists, so return-value explanation is not needed, and the tool is simple (one required param). However, the description leaves the agent guessing about its place in the content workflow relative to siblings and about what "frozen" means operationally, which is meaningful for a receipt/inspection tool.

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?

With a single parameter and 100% schema description coverage, the schema already explains plan_id fully. The description adds only a light scoping hint ("original API key's") and gives no extra syntax, format, or example beyond what the schema provides, so 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?

The description uses a specific verb ("Read") but the resource is described only in jargon — "frozen content review, approval state and observed operation" — and the word "publication" from the name/title never appears, so an agent cannot immediately map this to a saved publication receipt. It also never distinguishes itself from nearby siblings such as webanto_get_content_entry or webanto_get_asset_publication.

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?

There is no statement of when to call this versus the many sibling `get_*` tools, and no prerequisites or follow-up guidance. The only usage-adjacent signal is the implicit hint that this returns a saved/frozen snapshot, with no mention of what to call instead when a live read is wanted.

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