Get Personal Bonus Box Offers

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

Adds two genuinely useful traits beyond the readOnlyHint annotation: the fixed result cardinality (5 promotions) and a 30-minute cache window, which tells the agent not to poll for freshness. It stops short of stating that results depend on an active login session or what happens if the member has no offers.

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 resource and scope front-loaded and the caching caveat appended. Every clause carries information an agent would otherwise have to guess.

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 no output schema, the description carries the return-value burden but only supplies the count and the domain concept 'Bonus Box promotions'. That is enough to select and call the tool, though slightly thin on what a promotion entry contains compared with the sibling bonus-offer tooling.

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 the baseline is 4; there is nothing for the description to disambiguate. The implicit assumption that identity comes from the session rather than an argument is consistent with the empty schema.

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 and resource with concrete scope: exactly 5 personalized weekly Bonus Box promotions for the logged-in member. However, it never distinguishes itself from siblings like ah_get_bonus_offers, ah_get_promo_digest, or ah_activate_personal_bonus, so an agent must infer the boundary from the name alone.

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: the 'logged-in Albert Heijn member' framing hints that authentication is a prerequisite, and 'weekly Bonus Box' implies a once-a-week promotional check. No when-not conditions, no naming of ah_get_bonus_offers or ah_get_promo_digest as alternatives, and no hint that ah_activate_personal_bonus is the follow-up action for these offers.

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