implicit_create_universe

Create a process-local synthetic warehouse universe in memory from a count, returning a handle and version. Use it for bounded agent test data with no files or external execution.

Instructions

Create a process-local synthetic warehouse universe. Mutates memory only; max 16 universes. Returns handle/version; no files or external execution.

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

TDQS

A3.5/5.0
Behavior5/5

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

The description adds substantial context beyond the annotations: mutation is memory-only with no files, there is a hard cap of 16 universes, no external execution occurs, and a handle/version is returned. These are precisely the behavioral traits an agent needs before invoking a non-idempotent, non-read-only creation call.

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?

Three tight clauses, front-loaded with the verb and resource, then side-effect scope, then limit and return value. Every clause carries information; nothing is padding.

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?

For a one-parameter tool with annotations and no output schema, the description covers side effects, the cap, and the return shape well. However, it leaves the meaning and units of 'count' undefined and does not address failure modes when the 16-universe cap is hit, which is the most likely error an agent will encounter.

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 coverage is 0% and the single parameter 'count' is never explained in the description. Worse, the description's 'max 16 universes' sits awkwardly against the schema's maximum of 1000000 for count, leaving it unclear whether count is a number of universes (contradicting the cap) or something else. The description does not resolve this ambiguity.

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 and resource ('Create a process-local synthetic warehouse universe'), which is far more informative than the tool name alone. It does not explicitly contrast itself with siblings like implicit_inspect_universe or implicit_materialize, but the 'create' framing makes the distinction reasonably inferable.

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?

There is no explicit when-to-use or when-not-to-use guidance and no alternative is named. The 'max 16 universes' limit implies scarcity pressure but does not tell the agent which sibling to prefer or under what condition.

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