Install Thinking Cynefin
Pick your agent. Every command is ready to paste.
npx skills add tjboudreaux/cc-thinking-skills --skill thinking-cynefinThe open skills CLI detects your agents (Claude Code, Cursor, Codex and 70+ more) and installs to the right folder. Add -g to install globally.
01
Install it
Run the command above, or upload the folder in Claude.
02
Ask naturally
Describe the task. Your agent loads thinking-cynefin when the request matches its description.
03
Name it if needed
If it does not trigger, say “use the thinking-cynefin skill”. In Codex, type $thinking-cynefin.
Cynefin Classification
Classify by cause-effect, then use only the matching response mode. Wrong-domain method is the failure mode.
When to Use
- Unsure whether to run a playbook, analyze, probe, or stabilize.
- A method keeps failing and domain mismatch is plausible.
- A novel or mixed problem needs approach selection before solution work.
When NOT to Use
- Domain and method are already agreed—execute.
- Task is finding a specific cause, not choosing an approach.
- Classification done; switch to the domain method—do not re-label endlessly.
- Pure mechanical edits with no approach uncertainty.
Procedure
- State the unit. Name the decision, incident, or subsystem; if mixed, list separable parts.
- Probe cause-effect. Is the link obvious, expert-analyzable, retrospective only, or imperceptible in turbulence? Check predictability, urgency, and probe safety.
- Assign one domain per unit:
- Clear — obvious → Sense → Categorize → Respond with a runbook.
- Complicated — expert-analyzable → Sense → Analyze → Respond; several valid answers.
- Complex — emergent → Probe → Sense → Respond with safe-to-fail probes; amplify/dampen signals.
- Chaotic — no safe sensing time → Act → Sense → Respond; stabilize first.
- Disorder — unknown → split and classify each part.
- Mismatch check. Reject Clear if its runbook fails; Complicated if analysis cannot predict; Complex if probing is unsafe; Chaotic once safe probing becomes possible.
- Commit and stop. Output domain + first actions. Re-classify only on evidence of domain shift.
Stop when every unit has one domain, first actions, and a falsifier—or disorder is decomposed.
Output
unit: <decision/incident/part>
domain: clear | complicated | complex | chaotic | disorder
evidence: <cause-effect basis>
response_mode: <Sense-Categorize-Respond | Sense-Analyze-Respond | Probe-Sense-Respond | Act-Sense-Respond | decompose>
first_actions: <1-3 concrete steps>
falsifier: <what forces reclassification>
parts: <only if disorder>
Verification
- Falsify: Reliable prediction → not Complex. No safe probe → Chaotic. Working runbook → Clear.
- Stop: Stop classifying once the matched action is clear.
- Over-application guard: Do not call work Complex to avoid analysis or Complicated to avoid a standard fix. One label per unit; decompose multi-domain work.
Tips for Thinking Cynefin
- • Start a fresh session after installing so your agent picks up the new skill.
- • It is part of a pack with 28 skills. Install only the ones you need with --skill to keep triggers precise.
- • If two skills overlap, mention the one you want by name.
Questions about Thinking Cynefin
What does the Thinking Cynefin skill do?
When the right response mode is unclear, classify the cause-effect domain first; decompose disorder.
How do I install Thinking Cynefin?
Run "npx skills add tjboudreaux/cc-thinking-skills --skill thinking-cynefin" in your project. The skills CLI installs it for Claude Code, Cursor, Codex and 70+ other agents. In Claude on the web, upload the skill folder as a ZIP under Customize > Skills.
Does Thinking Cynefin work in Cursor and Codex?
Yes. Thinking Cynefin uses the open SKILL.md format, so it works in Claude Code, Claude, Cursor, OpenAI Codex, Gemini CLI, GitHub Copilot and other agents that support agent skills.
Is Thinking Cynefin free?
Thinking Cynefin is open source on GitHub under the MIT license. It is free to install; check the license before commercial use.
