add_multi_resource

Create a multi-resource operation that simultaneously seizes one token from each of several named resource pools and releases all upon completion.

Instructions

Add a MultiResource (AND-Resource) pattern — op requiring multiple simultaneous resources.

Seizes one token from each resource pool simultaneously and releases all upon completion. Unlike Machine (homogeneous channels), each pool can have a different name and capacity.

Use this for:

  • Painting: worker + spray gun + booth must all be free

  • Surgery: doctor + room + equipment required simultaneously

  • Welding: welder + welding machine + jig

Args: name: Instance name (e.g., "PaintBooth", "SurgeryRoom") resources: List of resource pool definitions. Each dict: {"name": str, "pool_size": int} Example: [{"name": "Worker", "pool_size": 3}, {"name": "Booth", "pool_size": 2}] processing_time: Mean processing time in time_unit distribution: Time distribution — "exp", "norm", "unif", "det" standard_deviation: Std dev for norm/unif (in time_unit) time_unit: Unit for time values — "s", "min", "h", or "d"

Behavior5/5

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

No annotations provided, but description fully discloses behavior: seizes one token from each pool simultaneously, releases upon completion. All parameters are explained in context.

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

Conciseness5/5

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

Efficient structure: definition, behavior, use cases, parameter list. Every sentence adds value without redundancy.

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

Completeness5/5

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

Given zero schema coverage and no output schema dependence, description fully covers all six parameters, behavior, and use cases. Complete for agent usage.

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

Parameters5/5

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

Schema has 0% coverage, but description adds detailed explanations for every parameter, including examples and defaults, far exceeding schema info.

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

Purpose5/5

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

Description clearly states 'Add a MultiResource (AND-Resource) pattern — op requiring multiple simultaneous resources.' It distinguishes from Machine, providing a specific verb-resource pair.

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

Usage Guidelines5/5

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

Explicitly lists use cases (Painting, Surgery, Welding) and contrasts with Machine, providing clear guidance on when to use.

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