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 strength is extreme token efficiency while remaining scannable. Its weakness is that it could benefit from slightly more detail on workflows involving destructive or multi-step operations (like grouping) and example outputs to confirm correct behavior.

Suggestions

Add a brief validation step or expected output example after key commands (e.g., what `blu devices` output looks like) to help confirm correct execution.

Expand the grouping workflow with a concrete multi-step example including verification (e.g., `blu group add <player>` → `blu group status` to confirm).

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 examples of output or more complex workflows (e.g., grouping a specific player, full TuneIn flow). The commands are real but somewhat surface-level.

2 / 3

Workflow Clarity

The quick start provides a reasonable sequence (discover → select → control), and there's a note to confirm target 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, single-purpose skill under 50 lines with no bundle files, the content is well-organized into logical sections (quick start, target selection, common tasks) and is easy to scan.

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) which gives it strong distinctiveness, but it is too terse and lacks explicit trigger guidance ('Use when...'). The capability listing stays at the category level rather than naming concrete actions, and it omits natural user terms like 'speaker', 'Bluesound', or 'music' that would help Claude match this skill to user requests.

Suggestions

Add an explicit 'Use when...' clause, e.g., 'Use when the user asks about BluOS, Bluesound speakers, or the `blu` command-line tool.'

Include natural trigger terms users might say, such as 'Bluesound', 'speaker', 'music playback', 'audio streaming', 'multi-room audio'.

Expand the capability list with more specific actions, e.g., 'discover players on the network, play/pause/skip tracks, create and manage speaker groups, adjust per-player volume'.

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 players on the network, play/pause/skip tracks, group/ungroup speakers, adjust volume levels'.

2 / 3

Completeness

Describes what the skill does (BluOS CLI operations) but completely lacks a 'Use when...' clause or any explicit trigger guidance for when Claude should select this skill. Per rubric guidelines, a missing 'Use when...' clause caps completeness at 2, and the 'what' portion is also thin, warranting a score of 1.

1 / 3

Trigger Term Quality

Includes some relevant keywords like 'BluOS', 'blu', 'playback', 'volume', and 'grouping', but misses common user terms like 'speaker', 'music', 'audio', 'Bluesound', 'streaming', 'player', or file extensions/protocol names that users might naturally mention.

2 / 3

Distinctiveness Conflict Risk

BluOS CLI ('blu') is a very specific niche tool for Bluesound/BluOS devices, making it highly unlikely to conflict with other skills. The domain is narrow and distinct enough that false triggers would be rare.
