C2.7/5.0
Behavior2/5

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

No annotations are provided, so the description carries the full behavioral burden. It implies a destructive mutation ('Remove') but never states whether the deletion is permanent, whether it errors when the constraint is absent, or whether any permissions/state preconditions apply. 'single' hints that only one constraint is affected, which is the only real behavioral signal.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single front-loaded sentence with zero filler. It is efficient, though for a three-parameter, un-annotated mutation tool the brevity is arguably under-specification rather than true conciseness.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a destructive, un-annotated tool with three fully undocumented required parameters, the description is inadequate. The presence of an output schema excuses it from explaining return values, but it still omits preconditions, error behavior, and parameter meaning.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, and the description supplies no semantics for cocktail_id, sort, or axis. 'axis' and 'recipe slot' loosely gesture at two of the three parameters, but no formats, valid values, or meaning of 'sort' (slot index? ordering key?) are given, so the description fails to compensate for the coverage gap.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb ('Remove') and resource ('a single axis constraint from a recipe slot'), which cleanly separates it from the set/get siblings (bar_set_band_constraint, bar_set_point_constraint, bar_get_slot_constraints). However, it never clarifies how an 'axis constraint' relates to the band/point constraints named by its siblings, leaving the domain model to inference.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No when-to-use guidance, no prerequisites (e.g., does the constraint need to exist, does the slot need to be populated), and no mention of alternatives such as bar_get_slot_constraints for inspection or the set_* tools for modification. The agent is left to guess the workflow position of this tool.

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