77%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is a well-structured skill with strong workflow clarity and actionable code examples. Its main weaknesses are the missing bundle files that the reference table points to, and some verbosity in the constraints and output templates sections that could be tightened. The core workflow with validation checkpoints is exemplary for a high-risk domain like legacy modernization.
Suggestions
Create the five referenced files (references/strangler-fig-pattern.md, etc.) to back the reference table, or remove the table if they won't be provided.
Trim the 'Knowledge Reference' keyword list and the 'Output Templates' section — replace with a concrete example of a migration plan output or remove entirely to save tokens.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill is reasonably efficient but includes some unnecessary content. The 'Knowledge Reference' section at the bottom is just a keyword list that adds no actionable value. The MUST DO/MUST NOT DO lists contain items Claude already understands (e.g., 'Communicate progress and risks transparently'). The Output Templates section is vague and could be tightened. | 2 / 3 |
Actionability | The skill provides fully executable Python code examples for the strangler fig facade, feature flags, and characterization tests. These are copy-paste ready, concrete, and directly illustrate the core patterns. The workflow steps include specific, measurable guidance (e.g., '80%+ coverage', traffic increment percentages). | 3 / 3 |
Workflow Clarity | The 5-step workflow has explicit validation checkpoints at every stage, including feedback loops (e.g., 'fix and re-validate'), rollback triggers, and clear sequencing. The traffic increment progression (5% → 25% → 50% → 100%) and the requirement to prove stability at 100% before removing legacy code are excellent validation gates for this inherently risky operation. | 3 / 3 |
Progressive Disclosure | The reference table is well-structured with clear 'Load When' guidance, providing good navigation signals. However, no bundle files were provided, meaning all five referenced files (strangler-fig-pattern.md, refactoring-patterns.md, etc.) are missing. The skill inlines substantial code examples that could arguably live in reference files, while the actual reference files that should contain detailed guidance don't exist. | 2 / 3 |
