bar_set_slot_meta

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

No annotations are provided, so the description carries full burden. It discloses a meaningful semantic: cross-category subs get a small flat penalty so in-category ranks first, and tolerance modes change behavior ('exact' requires a named bottle). However, it doesn't discuss whether this mutates existing slot metadata, idempotency, permissions, or error behavior when required params are missing.

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 the core purpose and prerequisite, then a compact Args block. Slightly verbose in restating param names, but each line adds semantic meaning not present in the schema. Well-structured for an 8-param tool.

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?

Given 8 params with 0% schema coverage and an output schema present (so return values needn't be explained), the description covers all parameters, the prerequisite relationship with constraint tools, and the cross-category penalty behavior. Nothing essential for correct invocation is missing.

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 0%, so the description must compensate and it does: it explains sort as 1-based BA sort index, defines each tolerance value ('exact'=named bottle, 'style'=vector match, 'any'=any in-category), states exact_ingredient_id is required when tolerance='exact', and clarifies also_accept_categories semantics and proof_min/proof_max as US proof range.

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+resource ('Declare the category + tolerance for a recipe slot') and distinguishes itself from siblings by naming what it must precede (axis constraints) and pointing to bar_describe_slots for the sort index. An agent can tell it apart from bar_set_point_constraint and bar_set_band_constraint.

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?

Explicitly states 'Required before setting axis constraints', which is a clear prerequisite and sequencing rule. It doesn't say when NOT to use it or fully contrast with the constraint-setting siblings, but the prerequisite and the pointer to bar_describe_slots give solid context.

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