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

Annotations already declare readOnlyHint=true, idempotentHint=true and destructiveHint=false, so the no-side-effect profile is covered structurally; 'before anything is charged' reinforces it but adds little new. The description says nothing about quote validity/expiry, what a quote is bound to, or how to subsequently act on it, which are the behavioral details that matter here.

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?

A single well-formed sentence with no filler, and the key constraint ('before anything is charged') is placed at the end where it reads as a guardrail. It is efficient, though it is so terse that the agent gets no routing or sequencing 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?

For a read-only, parameterless pricing call with annotations covering the safety profile, the description is minimally adequate. What is missing is the quote lifecycle: whether the returned price is time-limited, and which sibling (soclo_articles_draft, soclo_articles_publish_quote) consumes the quote next.

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?

The tool takes zero parameters, so per the baseline of 4 the schema carries the entire burden and the description has nothing parameter-level to compensate for. The one open question — which draft is being quoted when no identifier is supplied — is a schema design issue rather than a description omission.

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?

Names a specific verb ('quote the price') and a precise resource ('one article draft'), which is far more informative than the title alone. However, it does not distinguish this from the several sibling quote tools (soclo_articles_plan_quote, soclo_articles_publish_quote, soclo_articles_check_quote, soclo_articles_prices), so an agent cannot tell which quote variant applies from this text.

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?

'Before anything is charged' implies the ordering — quote first, then charge — which gives implied usage context. But there is no explicit when-to-use instruction, no exclusion of the alternative article quote/pricing siblings, and no stated prerequisites such as an existing draft.

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