encode_resistor_value

Convert a resistance value in ohms to its resistor color band sequence for standard or precision resistors.

Instructions

Encode a resistance value into color bands.

Converts a resistance value (in ohms) to the corresponding color band sequence.

Examples: 4700Ω, 5% → Yellow, Violet, Red, Gold 1000Ω, 1% → Brown, Black, Black, Brown, Brown (5-band)

A4.2/5.0
Behavior3/5

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

No annotations are provided, so the description fully bears the burden of behavioral disclosure. It describes the core transformation but omits details on input validation, error handling, or output format beyond examples. Adequate for a simple converter.

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?

The description is concise, front-loaded with the main purpose, and includes two informative examples with zero extraneous text. Every sentence adds value.

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

Completeness4/5

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

Given the tool's low complexity and the presence of an output schema (mentioned in context), the description adequately covers input usage and examples. It does not explain output format in text, but the examples suffice. Minor gap: no mention of tolerance value restrictions beyond schema enum.

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%, and the description adds meaning through examples showing how resistance_ohms, bands, and tolerance_percent map to output. The examples illustrate parameter usage effectively, exceeding the schema's basic definitions.

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 the tool encodes a resistance value into color bands, specifying the verb 'encode' and resource 'resistance value'. It distinguishes from the sibling 'decode_resistor_color_bands' tool by focusing on the encoding direction.

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

Usage Guidelines4/5

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

Description provides context for when to use (converting ohms to color bands) with clear examples. No explicit when-not or alternative tools mentioned, but the straightforward nature and sibling list implicitly guide usage.

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