64%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
A solid, actionable skill with clear CLI usage, good examples, and efficient table-based option documentation. Main weaknesses are the lack of validation/error handling guidance for a tool that performs destructive operations by default (replacing originals), some redundancy between the Preferences and Extension Support sections, and missing details about what EXTEND.md should actually contain.
Suggestions
Add a warning or verification note about the default destructive behavior (replacing originals without --keep), and suggest using --keep for first-time usage or batch operations.
Remove the redundant 'Extension Support' section at the bottom or merge it with the Preferences section to reduce token waste.
Provide a brief example of what EXTEND.md content looks like so users know the expected format and supported keys.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Mostly efficient with good use of tables, but includes some redundancy: the 'Extension Support' section at the end just restates what was already covered in the Preferences section. The script directory resolution instructions are a bit verbose. The description of resolving BUN_X could be tighter. | 2 / 3 |
Actionability | Provides fully executable CLI commands with clear options table, concrete examples covering common use cases (single file, directory, format override, JSON output), and shows expected output format. Copy-paste ready once variables are resolved. | 3 / 3 |
Workflow Clarity | This is essentially a single-command tool, so multi-step workflows aren't deeply needed. However, the EXTEND.md lookup priority is clearly sequenced. The skill lacks any validation or error handling guidance — what happens if no compression tool is available? What if the input file doesn't exist? For a tool that replaces originals by default (destructive operation), there's no warning or verification step. | 2 / 3 |
Progressive Disclosure | References EXTEND.md and scripts/main.ts appropriately, but no bundle files were provided to verify these exist. The 'Extension Support' section at the bottom is redundant with the Preferences section, creating unnecessary noise. The structure is reasonable but the EXTEND.md content/format is never shown, making it unclear what users should put there. | 2 / 3 |
