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

Annotations already declare readOnly=false, destructive=true, openWorld=true, idempotent=false, so the safety profile is largely covered. The description adds genuinely non-structured context: it reserves money or credits, and it only works when the organization has enabled "AI assistants can order and publish" — a prerequisite an agent cannot infer. It stops short of explaining failure behavior (insufficient balance, partial publish across sites, refunds), which is the remaining gap for a destructive spending tool.

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?

Front-loaded with what the tool does, then the prerequisite, then the when/when-not guidance. Slight redundancy between "Rezervă bani sau credite" and the later "Spends credits or money", but the repetition reinforces a high-stakes fact rather than wasting space.

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 values need no explanation, and annotations cover the mutation/idempotency profile. Given that this is a money-spending, non-idempotent, destructive operation, the description supplies the critical gating and cost context; what is missing is post-call semantics (partial failure across multiple sites, refund behavior).

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 100%, so every parameter is already documented, including provenance hints (siteIds from search_catalog or plan_budget, articleId from list_articles or create_article). The description adds only the high-level notion of one-or-more sites and a specific draft; it does not clarify how packageTypeId/promoCode interact with the reserved amount. 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?

States a specific verb and resource ("Trimite un articol spre publicare"), the fan-out scope ("pe unul sau mai multe site-uri"), and a gating prerequisite (org must have enabled AI ordering). It also names the sibling tools (plan_budget, get_site) that cover the cases this tool does not, so an agent can separate it from cost-estimation tools without opening schemas.

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?

Explicit positive condition (user has explicitly confirmed a specific draft on specific sites, with the total shown) and explicit negative conditions (not confirmed; cost estimation → use plan_budget or get_site). Both when-to-use and when-not-to-use plus named alternatives are present.

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