Quality

Content

72%

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

This is a concise, well-structured skill that efficiently communicates CLI usage patterns for BluOS control. Its main weakness is that some commands are shown as patterns rather than fully concrete examples with expected outputs, and the workflow around destructive operations (grouping, playback changes) lacks explicit validation steps.

Suggestions

Add a brief example showing expected output from `blu devices` and `blu --device <id> status` so Claude knows what to parse and verify

Add a validation/confirmation step for grouping operations (e.g., check group status after add/remove to verify success)

DimensionReasoningScore

Conciseness

Extremely lean and efficient. Every line provides actionable information without explaining what BluOS is or how CLI tools work. No wasted tokens.

3 / 3

Actionability

Provides concrete commands that are copy-paste ready, but lacks complete workflow examples (e.g., full grouping sequence, what output to expect). The commands are real but some are incomplete patterns rather than fully executable examples.

2 / 3

Workflow Clarity

The quick start provides a reasonable sequence (discover → select → control), and there's a note to confirm target device before changing playback. However, there are no explicit validation checkpoints or error recovery steps for potentially disruptive operations like grouping changes.

2 / 3

Progressive Disclosure

For a simple, short skill with no bundle files, the content is well-organized into logical sections (quick start, target selection, common tasks, tips). No need for external references given the scope.

Description

40%

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 identifies a clear niche (BluOS CLI tool) which makes it distinctive, but it is too terse to be effective for skill selection. It lacks a 'Use when...' clause entirely and lists only high-level action categories rather than specific concrete actions. Users searching for help with Bluesound speakers, multi-room audio, or music streaming might not trigger this skill.

Suggestions

Add an explicit 'Use when...' clause, e.g., 'Use when the user asks about BluOS, Bluesound speakers, multi-room audio setup, or controlling music playback via the blu CLI.'

Expand action descriptions to be more concrete, e.g., 'Discovers BluOS players on the network, controls music playback (play, pause, skip), groups and ungroups speakers for multi-room audio, and adjusts volume levels.'

Include additional natural trigger terms users might say, such as 'Bluesound', 'speakers', 'multi-room', 'music', 'audio streaming', or 'NAD'.

DimensionReasoningScore

Specificity

Names the domain (BluOS CLI) and lists several action categories (discovery, playback, grouping, volume), but these are high-level categories rather than specific concrete actions like 'discover devices on the network, play/pause/skip tracks, group speakers together, adjust volume levels'.

2 / 3

Completeness

Provides a brief 'what' (BluOS CLI for discovery, playback, grouping, volume) but completely lacks any 'when' clause or explicit trigger guidance. Per rubric guidelines, a missing 'Use when...' clause caps completeness at 2, and the 'what' itself is also quite thin, warranting a score of 1.

1 / 3

Trigger Term Quality

Includes 'BluOS', 'blu', 'playback', 'grouping', and 'volume' which are relevant keywords, but misses common user terms like 'speakers', 'music', 'audio', 'streaming', 'Bluesound', or 'multi-room'. The CLI tool name 'blu' is helpful but niche.

2 / 3

Distinctiveness Conflict Risk

BluOS CLI is a very specific niche tool ('blu' command), making it highly unlikely to conflict with other skills. The combination of the product name and CLI tool name creates a clear, distinct identity.
