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

No annotations are provided, so the description carries the full burden. It discloses two behavioral facts (15% discount and a permalink result), but says nothing about side effects, whether a record is created, what happens when no matching ottoman or chair exists, or how the budget cap alters results.

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 front-loaded sentence with no filler, and the bundle composition plus discount are stated up front. It is efficient, though the terseness contributes to the missing behavioral detail rather than remedying it.

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 two-parameter tool with no output schema, the description covers the core behavior, but it omits what the permalink contains, how budget_cap interacts with selection, and what the failure mode looks like for an unpairedable sofa. Adequate but with clear gaps.

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 both parameters are already documented in the schema. The description confirms the anchor sofa concept but adds no meaning about base_product_handle syntax or how budget_cap is applied (hard failure vs. part exclusion), leaving it at baseline.

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 action and resource: pairs an anchor sofa with an ottoman and accent chair to form a discounted bundle, which distinguishes it from constraint-search or comparison siblings. It does not name any sibling or explicitly contrast with find_products_by_constraints or create_checkout_handoff, so differentiation is only implicit.

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?

There is no when-to-use or when-not-to-use guidance and no mention of alternatives such as find_products_by_constraints for open-ended browsing. The agent must infer that this is for building a curated 3-piece set from a known sofa handle.

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