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

readOnlyHint=true already covers the safety profile, so the description's added value is in disclosing the returned payload (buyer, line items, taxes, totals, dates, currency, PDF link) and the underlying endpoint GET /ponuda?id=. That is genuinely useful given there is no output schema. It omits error behavior for an invalid or missing offer, which keeps it below a 5.

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 compact sentences, front-loaded with what the tool returns and followed by the id-provenance hint. No filler. The endpoint string is low value for an agent but cheap and occasionally useful for debugging.

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 one required parameter, no output schema, and readOnlyHint covering safety, the description supplies exactly the missing piece: the shape of the returned offer. Only the absence of any failure-mode or not-found context keeps it from a 5.

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% and the schema field already says "Offer id (hash) from solo_list_offers", so the description's "long hash from solo_list_offers" largely restates it. The only marginal addition is the word "long" hinting at the id format. Baseline 3 is appropriate when the schema carries the parameter documentation.

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?

Specific verb + resource ("Get one offer") plus an enumeration of the payload (buyer, line items, taxes, totals, dates, currency, PDF link), which makes it clearly a single-record fetch. It distinguishes itself from solo_list_offers by referencing it as the source of the id, but never contrasts with solo_get_offer_status, the sibling an agent could plausibly confuse it with.

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?

Usage is only implied through the workflow hint that the id comes from solo_list_offers. There is no explicit statement of when to call this versus solo_get_offer_status, nor any note about what happens when the id is unknown or stale. Adequate for a trivial single-id getter, but no real routing guidance.

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