description: Create Chinese monospaced compass-style PDCA or CAPD problem-solving cards using East-West-South-North-Center layout, full-width and half-width spaces, diagonal Unicode arrows, and strict Chinese character limits. Use when Codex needs to turn a problem, incident, decision tradeoff, root-cause analysis, improvement cycle, or CAPD/PDCA workflow into a square text diagram, Hermes/Discord-ready card, or Chinese 方位九宮圖 with center ◎, north Plan, east Do, south Check, west Action, and four diagonal transition arrows.

PDCA / CAPD Compass Card

Use this skill to transform a problem into a Chinese text diagram shaped like a compass: North, East, South, West, four diagonal arrows, and a center ◎ core. The output should feel like a fixed-width visual card, not a prose explanation.

Core Rules

• Use a fenced `text` code block for the final diagram.
• Prefer Chinese labels and short phrases.
• Use full-width spaces `　` for large horizontal alignment and half-width spaces only for small adjustments.
• Keep the center phrase at 8 Chinese characters or fewer, prefixed with `◎`.
• Keep each outer compass phrase at 8 Chinese characters or fewer when the user requests strict eight-character limits.
• Make the diagram readable in a monospaced environment such as Discord, Hermes, terminal, or Markdown preview.
• Avoid over-explaining inside the diagram. Let placement, arrows, and labels carry the structure.

Compass Mapping

• North `北`: `【Ｐ｜Plan 計畫】` for goals, options, choices, hypotheses, and intended destination.
• East `東`: `【Ｄ｜Do 執行】` for concrete measures, steps,现场 action, and use of methods.
• South `南`: `【Ｃ｜Check 檢查】` for facts, results, confirmation, and next-cycle evidence.
• West `西`: `【Ａ｜Action 改善】` for cause discovery, root-cause pursuit, correction, and institutional repair.
• Center `中`: `【◎核心】` for the problem essence, incident, contradiction, or decision point.

For CAPD, the cycle begins at Check:

• `Check -> Action -> Plan -> Do -> Check`
• Use CAPD when the task starts from現況認識, incident confirmation, observation, or evidence.

For PDCA, the cycle begins at Plan:

• `Plan -> Do -> Check -> Action -> Plan`
• Use PDCA when the task starts from a goal, plan, proposal, or project improvement loop.

Arrow Rules

Use 45-degree Unicode arrows at the four corners:

• `↗` means Action -> Plan: root causes become better plans.
• `↘` means Plan -> Do: plans become concrete execution.
• `↙` means Do -> Check: execution produces results to inspect.
• `↖` means Check -> Action: inspection returns to root-cause improvement.

Place arrows between the compass quadrants with enough full-width spacing to preserve the visual loop.

Output Template

Adapt this template. Keep line lengths visually balanced rather than mathematically perfect.

Construction Workflow

1. Extract the center problem as a phrase of 8 Chinese characters or fewer. 2. Decide whether the loop is CAPD or PDCA from the user's starting point. 3. Fill the four directions:

• Plan: options, desired end state, chosen principle.
• Do: immediate measures and executable steps.
• Check: confirmed facts, result state, what to inspect next.
• Action: causes, failures, root-cause questions, recurrence prevention.

4. Compress each phrase until it fits the requested width. 5. Render a single `text` code block with full-width spacing and arrows. 6. If helpful, add a brief note after the diagram listing the cycle order and any assumptions.

Phrase Compression

When content is too long, compress meaning before widening the diagram:

• `老虎已經逃出籠子` -> `老虎逃走`
• `人命安全與動物保護之間的取捨` -> `人獸取捨`
• `封鎖現場並避免民眾靠近` -> `封鎖現場`
• `防止同類事件再次發生` -> `防止再發`

Prefer four-character and six-character Chinese compounds when possible. Use eight characters only when needed.
