63%Weight 40%Scale 1-5Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is a strong, actionable skill: the three-way merge logic is precisely specified with executable commands, the safety invariant (backed-up files are definitionally modified) is well-enforced through conflict escalation, and the workflow has clear sequencing with a closing checklist. Its weaknesses are repetition — a six-branch copy-pasted detection script and a triple-stated invariant — and the absence of any bundle files, which forces ~90 lines of detection code inline and leaves the backup-meta.json schema unspecified.
Suggestions
Replace the six copy-pasted env-var detection blocks with a single loop over (env var, subdirectory) pairs, or move the detection script into a scripts/ file and reference it from SKILL.md — this fixes both the conciseness and progressive disclosure issues.
Show the expected structure of backup-meta.json (at least the key field names) so Step 4's per-file iteration can be executed exactly as written.
State the 'never conclude no custom content' invariant once (in purpose) and reference it briefly elsewhere; add an explicit post-merge verification step (e.g., diff the merged file against the backup to confirm user changes are present) to close the workflow's validation gap.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is mostly efficient domain-specific guidance (no explanations of concepts Claude already knows), but it could be tightened: the ~90-line bash detection block repeats six nearly identical env-var branches that a loop over tool/env pairs would collapse to ~15 lines, and the 'never conclude no custom content' invariant is stated three times (purpose, Step 4 CRITICAL RULE, and the Never-report line). Fits anchor 3 ('Mostly efficient but... could be tightened'), not anchor 4 which requires only minor trims. | 3 / 5 |
Actionability | Concrete, executable guidance throughout: copy-paste-ready bash for patch-directory detection, exact git commands for baseline extraction ('git log --diff-filter=A', 'git show {install_commit}:{file_path}'), explicit merge classification rules, and literal output templates. The minor gap keeping it below anchor 5 is that backup-meta.json's schema is never shown, so Step 4's iteration over it lacks the key names needed to execute precisely. | 4 / 5 |
Workflow Clarity | A clear six-step numbered sequence with checkpoints appropriate to a batch/destructive operation: a conflict feedback loop (flag both versions and ask the user), per-file status reporting with a summary of what was preserved, and a final success_criteria checklist ('All backed-up patches processed — zero files left unhandled'). Below anchor 5 because there is no explicit post-merge validation step verifying the written file actually contains the user's changes before reporting success. | 4 / 5 |
Progressive Disclosure | Sections are well-organized (purpose / process / success_criteria with numbered steps), and no references are buried. However, the skill is a single file with no bundle: the ~90-line runtime-detection bash block is inline content that clearly belongs in a scripts/ helper, and the merge heuristics could be split into a reference file, which would leave SKILL.md as a lean overview. Fits anchor 3 ('content that should be separate is inline'). | 3 / 5 |
