cfx_model_context

Get targeted CFX model context slices with actions like summary, find objects, and state. Control response size via max_items for efficient, compact queries.

Instructions

Return a targeted, compact CFX model context slice. Actions: summary, list_named_objects, find_named_object, select_named_objects, state, api_help, find_api, allowed_values, targeted_context. Use max_items to keep responses small.

A3.9/5.0

Behavior3/5

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

No annotations are provided, so the description carries the burden. It discloses that responses are 'targeted, compact' and that max_items limits size, but does not state whether the tool is read-only, possible errors, or any side effects. This is adequate but not rich.

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?

Two concise sentences, front-loaded with purpose, followed by a compact action list and max_items guidance. No redundant wording.

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

Completeness3/5

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

Given the tool has many actions and parameters, the description covers the core purpose and output control but lacks guidance on when to choose this tool over siblings or how to select between actions. Output schema covers return values, so no need to explain them.

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

Parameters4/5

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

Schema coverage is 100%, so baseline is 3. The description adds value by enumerating valid action values and explaining the purpose of max_items, which goes beyond the schema's generic descriptions.

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?

The description uses a specific verb ('Return') and resource ('CFX model context slice'), and enumerates distinct actions. It clearly distinguishes this as a context-query tool from siblings like run_code or connect.

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

Usage Guidelines3/5

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

The description implies when to use the tool (for context queries) and lists actions, but does not explicitly state when not to use it or mention alternatives among sibling tools. No exclusionary or comparative guidance is given.

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