Mostly efficient with tables and executable code, but includes a mild fluff line ('vnpy is the most widely-used open-source quant framework in mainland China (39k+ GitHub stars)') and redundancy between the inlined full template and scripts/cta_template.py. Matches the score-2 anchor of mostly efficient with some tightening possible. Not 3 because of the marketing aside and template duplication; not 1 because it does not pad with concepts Claude already knows.

Provides a fully executable CtaTemplate skeleton, copy-paste-ready backtester block, and concrete mapping tables (Python→ArrayManager, Signal→Order). Matches the score-3 anchor of fully executable, specific, copy-paste-ready guidance. Not 2 because the code is real and complete rather than pseudocode with missing details.

Two clearly sequenced numbered workflows plus a 'Quality Checklist' acting as an explicit validation checkpoint before save, with feedback-oriented items ('on_bar calls self.cancel_all() at the start', 'load_bar(n) warmup ... at least max(all indicator windows) + 2'). Matches the score-3 anchor with explicit validation steps and a checklist. Not 2 because checkpoints are explicit, not merely implied.

Sections are well-organized and the body references a real bundle file (scripts/cta_template.py, verified present) plus external docs, but the full template is inlined in SKILL.md while cta_template.py covers overlapping ground — content that could be separate lives inline. Matches the score-2 anchor of some structure but inlined content that could be split. Not 3 because the inlined template duplicates the referenced file rather than pointing cleanly to one level of detail.

Quotes concrete actions: 'Export a Vibe-Trading backtest strategy to a runnable vnpy CtaTemplate Python class' and 'supports A-share equities, futures, and crypto via BarGenerator + ArrayManager' — multiple specific concrete actions matching the score-3 anchor. Not 2 because it lists several distinct, tangible capabilities rather than naming only a domain and partial actions.

Clearly answers 'what' ('Export ... to a runnable vnpy CtaTemplate Python class') but has no 'Use when...' trigger clause or equivalent explicit 'when' guidance in the description itself — the trigger guidance lives only in the body. Per rubric guideline, a missing explicit trigger clause caps completeness at 2, so not 3.

Contains natural terms users would say: 'vnpy', 'backtest strategy', 'CtaTemplate', 'A-share equities, futures, and crypto'. Good coverage of the vocabulary a user needing this export would naturally use. Not 2 because it goes well beyond a single generic keyword with several relevant, domain-accurate terms.

Highly distinct niche — exporting to a specific framework (vnpy) for specific asset classes — unlikely to trigger for unrelated skills. Not 2 because the combination of 'vnpy', 'CtaTemplate', and asset-class specifics carves a clear, non-overlapping trigger space.
