71%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.
A well-structured, highly actionable skill for translating requirements into TLA+ properties, with excellent progressive disclosure into three real reference files. Its main weaknesses are over-explanation of formal-methods basics Claude already knows (pitfalls, best practices, operator definitions) and placeholder templates that keep some examples from being fully executable, plus a missing output-validation step in the workflow.
Suggestions
Cut or drastically trim the 'Best Practices' and 'Common Pitfalls' sections — they restate formal-methods basics (safety vs. liveness, fairness needed for liveness) that Claude already knows; keep only guidance specific to this translation task.
Replace placeholder predicates in the Step 3 templates and Pattern 4 ('event_A_occurred_before', 'predicate_over_state_variables', bare 'P'/'Q') with concrete, syntactically valid TLA+ definitions so every shown property is copy-paste ready.
Add an explicit validation step to the workflow — e.g., 'check the generated property parses (SANY) and is checkable by TLC before presenting it; if not, fix and re-check' — turning Step 5's verification notes into a feedback loop.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The workflow, patterns, and output format are dense and skill-specific, but sections like "Common Pitfalls" ("Safety: 'Nothing bad happens' ([]P)", "Liveness properties often require fairness assumptions"), the generic "Best Practices" items ("Use meaningful names", "Start simple"), and Step 3's teaching of basic temporal operators ([] = always, <> = eventually) restate formal-methods knowledge Claude already has and duplicate content in references/tlaplus_syntax.md. Mostly efficient, but a few full sections could be trimmed, which matches the anchor-3 example better than anchor 4's 'minor instances'. | 3 / 5 |
Actionability | Mostly concrete, syntactically valid TLA+ (MutualExclusion, EventualService, SafeModeConstraint, AllTerminate, BufferSafety) plus a precise 7-part output format. However, several templates are placeholder pseudocode — "StateInvariant == predicate_over_state_variables", "Safety == []P", and Pattern 4's undefined "event_B_occurred => event_A_occurred_before" — so not everything is copy-paste ready, matching anchor 4 rather than anchor 5. | 4 / 5 |
Workflow Clarity | The five-step sequence (Analyze → Resolve Ambiguities → Map to Constructs → Generate → Explain) is clearly ordered, and ambiguity resolution acts as an explicit interactive checkpoint ("ask the user" with example questions). The gap is output validation: the skill explains how TLC will check properties but never instructs validating that the generated property parses (e.g., with SANY) before presenting it — a missing checkpoint that fits anchor 4's 'most checkpoints present; minor validation gaps' rather than anchor 5's explicit validation steps. | 4 / 5 |
Progressive Disclosure | The body is a clear overview (workflow, four key patterns inline, output format) with bulk material split into three real, one-level-deep reference files, each well-signaled at point of use ("See [references/clarification_patterns.md] for common question templates") and again in a closing References section. Verified: all three referenced files exist and contain no nested references, matching the anchor-5 example of a clear overview with well-signaled one-level-deep references. | 5 / 5 |
