Quality
Discovery
85%Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.
This is a well-structured description that clearly communicates both what the skill does and when to use it, with an explicit 'Use when' clause. The main weakness is that trigger terms could be more comprehensive, missing common shorthand like 'env' or related terms users might naturally use. Overall it's a strong description with good specificity and distinctiveness.
Suggestions
Add common natural trigger terms users would say, such as 'env command', 'export', 'PATH', 'shell environment', or 'printenv' to improve keyword coverage.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple specific concrete actions: 'run a command with a modified environment', 'print the current environment', 'setting environment variables for a single command', 'clearing the environment', 'inspecting variables'. | 3 / 3 |
Completeness | Clearly answers both 'what' (run a command with modified environment, print current environment) and 'when' (explicit 'Use when' clause covering setting env vars, clearing environment, inspecting variables). | 3 / 3 |
Trigger Term Quality | Includes relevant terms like 'environment variables', 'modified environment', 'clearing the environment', but misses common natural user terms like 'env', 'export', 'PATH', 'shell variables', or the actual command name (likely 'env'). | 2 / 3 |
Distinctiveness Conflict Risk | Clearly scoped to environment variable manipulation and inspection for command execution, which is a distinct niche unlikely to conflict with other skills. | 3 / 3 |
Total | 11 / 12 Passed |
Implementation
85%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is a solid reference skill for the `env` command with excellent actionability through concrete examples and a complete flags table. It's well-structured for a simple utility reference. Minor verbosity in the gotchas section (explaining shebang mechanics and shell equivalences that Claude already knows) prevents a top conciseness score.
Suggestions
Trim the Gotchas section to only non-obvious behaviors (e.g., remove the explanation that env in shebangs finds executables in $PATH, which Claude already knows). Keep the -S kernel behavior note and the -i empty environment warning.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Mostly efficient but includes some unnecessary content. The full flags table with every option (including --help, --version) is somewhat verbose for Claude, and the gotchas section explains things Claude likely already knows (like how shebangs work). However, it's not egregiously padded. | 2 / 3 |
Actionability | Provides fully executable, copy-paste ready examples covering all major use cases. The examples are concrete with real commands and realistic variable names (DB_HOST, DB_PORT), and the flags table gives specific, complete reference information. | 3 / 3 |
Workflow Clarity | This is a simple, single-purpose skill (running a command with modified environment). There are no multi-step processes or destructive operations requiring validation checkpoints. The single actions are unambiguous and clearly presented. | 3 / 3 |
Progressive Disclosure | For a simple skill under 50 lines of substantive content with no need for external references, the content is well-organized into clear sections (Synopsis, Flags, Examples, Gotchas) that are easy to navigate and appropriately scoped. | 3 / 3 |
Total | 11 / 12 Passed |
