Quality

Content

78%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The content is well-structured, lean, and actionable with concrete tool calls and a useful troubleshooting table, and it uses progressive disclosure effectively by deferring board pinouts and device register maps to two real, one-level-deep reference files.

DimensionReasoningScore

Conciseness

The body is efficient and assumes Claude's competence (no explanations of what I2C/SPI is), with concrete tool calls and a tight troubleshooting table; only minor instances could be trimmed (e.g. the 'Common steps' list partly echoes the board-pinout reference), so it sits just below the lean 'every token earns its place' bar of 5.

4 / 5

Actionability

It provides concrete, copy-paste-style tool calls (`i2c detect`, `i2c scan (bus: "1")`, `i2c read (...)`, `spi list`, `spi read (...)`) plus executable shell commands (`modprobe i2c-dev`, `/etc/init.d/S30wifi stop`); the only gap is that board-specific pinmux `devmem` addresses are deferred to the reference, keeping it just below fully executable 5.

4 / 5

Workflow Clarity

There is a clear numbered Quick Start sequence, a numbered pinmux setup with an explicit 'Verify with i2c detect and i2c scan' checkpoint, a Safety section requiring `confirm: true` for destructive writes, and a troubleshooting table for error recovery; it falls just short of 5 because inline validate-then-retry feedback loops are not spelled out step by step.

4 / 5

Progressive Disclosure

SKILL.md is a concise overview with two well-signaled, one-level-deep references (`references/board-pinout.md` and `references/common-devices.md`, both real files that do not nest further), with detail appropriately split out into those files, matching the 'clear overview with well-signaled one-level-deep references' anchor.

Description

65%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description is distinctive and uses good natural trigger terms including specific board names, but it lacks an explicit 'Use when...' trigger clause and leans on a generic 'control' verb rather than enumerating concrete actions.

Suggestions

Add an explicit 'Use when...' trigger clause, e.g. 'Use when the user needs to read sensors, drive displays, or configure I2C/SPI peripherals on Sipeed boards (LicheeRV Nano, MaixCAM, NanoKVM).' to raise completeness above 3.

Replace the generic 'control' with concrete actions (e.g. 'scan, read from, and write to I2C/SPI peripherals') to lift specificity toward 4-5.

Consider adding common peripheral synonyms users say ('sensors', 'displays', 'IMU', 'OLED') to round out trigger term coverage toward 5.

DimensionReasoningScore

Specificity

The description names the domain ('I2C and SPI peripherals on Sipeed boards') and two actions ('Read and control'), but 'control' is generic rather than a list of several specific actions like scan/write/configure, so it does not reach the 'several specific actions' bar of 4.

3 / 5

Completeness

It clearly states what the skill does ('Read and control I2C and SPI peripherals...') but has no 'Use when...' clause or equivalent explicit trigger guidance, which per the judging guidelines caps completeness at 3.

3 / 5

Trigger Term Quality

Natural keywords a user would say are present ('I2C', 'SPI', 'peripherals', 'Sipeed boards', plus board model names 'LicheeRV Nano, MaixCAM, NanoKVM'), giving good coverage; a few natural synonyms (e.g. 'sensors', 'displays') are missing so it stops short of 5.

4 / 5

Distinctiveness Conflict Risk

It carves out a clear niche (I2C/SPI on specific Sipeed board models) with distinct triggers and minimal conflict risk against other skills, matching the 'clear niche with distinct triggers' anchor.
