Quality

Discovery

67%

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 concise and specific about its capabilities, clearly identifying the domain of managing CLI agents via tmux with cron scheduling. Its main weakness is the lack of an explicit 'Use when...' clause, which caps completeness. Adding natural trigger terms that users might actually say would also improve discoverability.

Suggestions

Add a 'Use when...' clause, e.g., 'Use when the user wants to run multiple agents in parallel, orchestrate background CLI tasks, or schedule agent runs.'

Include more natural user-facing trigger terms like 'parallel agents', 'background tasks', 'run multiple agents', 'agent orchestration', or 'batch agent execution'.

DimensionReasoningScore

Specificity

Lists multiple specific concrete actions: 'start/stop/monitor/assign' agents, mentions 'tmux sessions' as the mechanism, and 'cron-friendly scheduling' as an additional capability. These are concrete, actionable operations.

3 / 3

Completeness

Clearly answers 'what does this do' (manage local CLI agents via tmux with scheduling), but lacks an explicit 'Use when...' clause or equivalent trigger guidance. The when is only implied by the description of capabilities.

2 / 3

Trigger Term Quality

Includes relevant keywords like 'tmux', 'CLI agents', 'cron', 'scheduling', 'start/stop/monitor'. However, it misses natural user terms like 'background tasks', 'parallel agents', 'agent orchestration', or 'run multiple agents'. Users might not naturally say 'tmux sessions' when asking for this functionality.

2 / 3

Distinctiveness Conflict Risk

Highly distinctive with a clear niche: the combination of 'tmux sessions', 'local CLI agents', and 'cron-friendly scheduling' is very specific and unlikely to conflict with other skills. This is a well-defined operational domain.

Implementation

29%

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

The skill provides a useful set of CLI commands but lacks the depth needed to be truly actionable. There is no workflow sequencing, no validation/error handling guidance, and no supporting files or references for agent configuration or cron setup. The boilerplate limitations section wastes tokens without adding value.

Suggestions

Add a step-by-step workflow (e.g., 1. Run `doctor` to verify prerequisites → 2. Configure agents in `agents/` → 3. Start agents → 4. Monitor and verify output) with explicit validation checkpoints after each step.

Include a concrete example of an agent configuration file and a cron entry, rather than deferring to 'see the repo'.

Remove the generic 'Limitations' boilerplate and replace it with skill-specific constraints (e.g., max concurrent agents, tmux version requirements, known failure modes).

Add expected output examples for key commands (e.g., what `list` and `doctor` return) so Claude can verify success or diagnose failures.

DimensionReasoningScore

Conciseness

Mostly efficient, but the 'Limitations' section is boilerplate filler that doesn't add skill-specific value (e.g., 'Do not treat the output as a substitute for environment-specific validation' is generic advice Claude already knows). The 'When to Use' section is slightly redundant with the commands shown.

2 / 3

Actionability

Provides concrete CLI commands which is good, but they are listed without explaining expected outputs, flags, or error cases. There's no executable example of agent configuration, cron scheduling setup, or what the agents/ directory should contain—key details are deferred to 'see the repo' without specifics.

2 / 3

Workflow Clarity

There is no sequenced workflow—commands are listed but not ordered into a coherent process (e.g., doctor → configure → start → monitor → assign). There are no validation checkpoints, no error recovery guidance, and no feedback loops for monitoring or troubleshooting failed agents.

1 / 3

Progressive Disclosure

No bundle files are provided, and the skill references 'see the repo for examples' without any linked files, configuration templates, or structured navigation. There's no layered content organization—everything is in a flat, shallow document with no supporting references.
