recommend_faith_gifts

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

No annotations are provided, so the description must carry the burden. It does disclose the core behavior—a non-mutating recommendation/consulting action—but it does not state what the response looks like, whether it checks live product availability, or how it handles missing optional inputs.

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?

Single sentence, front-loaded with the tool's role ('Smart faith gift consultant'), and packs product categories plus input dimensions without filler. The only minor word is 'Smart,' which doesn't undermine its efficiency.

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 simple recommender, the description plus schema is adequate for basic invocation, but with no output schema and no annotations it leaves gaps: output format, handling of optional parameters, and relationship to product-search siblings are not explained.

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?

All five parameters are documented in the schema (100% coverage), so the description adds no new syntax or format details. It merely restates the parameter dimensions (occasion, budget, style vibe, scripture theme) in prose, which is helpful orientation but not semantic enrichment.

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 ('recommends') and names the exact resource ('personalized Christian streetwear, hats, EVA foam clogs, and accessories'), with the input dimensions that drive the recommendation. This clearly differentiates it from sibling product-search/detail tools, which are about retrieving existing products rather than acting as a gift consultant.

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 implied by the 'gift consultant' framing: it should be used when a personalized faith-gift recommendation is needed. However, it never explicitly says when not to use it or names alternatives (e.g., search_armornglory_products for direct product lookup).

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