Operator Signature — Portable Identity Object

operator_signature
Read-onlyIdempotent

Computes a normalized operating signature from 4 token pillars or a codename. Returns a signature code, a legacy six-label signature_label, dominant trait, and closest comparable operators from the live board. The deprecated archetype field is retained as a compatibility alias; these labels are not the 10-type Build Archetypes reference extension.

B3.1/5.0
Behavior4/5

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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so the safety profile is covered. The description adds useful behavioral context: it computes a normalized signature from pillars or codename, returns several derived fields, and clarifies that the deprecated archetype field is a compatibility alias not part of the 10-type Build Archetypes. No contradiction with annotations.

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?

The description is three dense sentences with the primary purpose front-loaded and no filler. The disambiguation sentence is useful, though the heavy jargon may reduce clarity for an agent encountering this tool for the first time.

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?

With 7 parameters, low schema coverage, and no output schema, the description should provide more complete guidance but omits parameter-level semantics for window, input, output, cache_read, and cache_write. It lists return fields but does not explain their format or relationship to the inputs, leaving significant gaps for correct invocation.

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 only 29%, so the description must compensate for poorly documented parameters, but it only mentions '4 token pillars or a codename' without mapping those to specific parameters like input, output, cache_read, cache_write, or window. The description adds some semantic value but leaves most parameter meanings unclear.

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?

The description clearly states a specific verb ('Computes') and resource ('normalized operating signature'), and it names the main inputs and outputs. It does not explicitly distinguish this tool from siblings like who_operates_like_me or get_operator, though it does disambiguate from the Build Archetypes reference extension.

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?

The description explains what the tool computes but provides no guidance on when to use it versus alternatives such as who_operates_like_me or get_operator. There is no mention of prerequisites, conditions, or exclusions, so an agent must infer usage purely from the output description.

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