## What it does

The skill pushes the agent to start from what's already at hand instead of from a fixed goal. It inventories means: who you are (skills, constraints, values), what you know (domain, tools, data), and who you can reach. An ideal plan is explicitly not an input.

Next it sets affordable loss — time, money, reputation, opportunity cost — and picks one action inside those caps. That action has to earn either a real commitment from someone or discriminating information. Feedback without commitment gets discarded. Surprises count as new means, not as a reason to restore the old plan.

You get an effectuation brief with `means`, `affordable_loss`, `next_action`, `commitments_sought_or_won`, `contingencies_used`, `emerging_goal`, and `stop_or_loop`. The skill checks itself: a brief that starts from a fixed goal and backfills resources gets rewritten. Where a reliable forecast and a known playbook exist, the skill tells you not to use it and to plan causally instead. Worth checking whether you actually face uncertainty or just routine execution.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add tjboudreaux/cc-thinking-skills --skill thinking-effectuation -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/thinking-effectuation/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/thinking-effectuation/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add tjboudreaux/cc-thinking-skills --skill thinking-effectuation -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/thinking-effectuation/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add tjboudreaux/cc-thinking-skills --skill thinking-effectuation -a cursor
```

2. **Manually: put the files in place**

```bash
npx skills add tjboudreaux/cc-thinking-skills --skill thinking-effectuation -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

## When to use it
- pick a first move when market or technology forecasts are untrustworthy
- cap time and money losses before the project starts
- tell real partner commitments apart from polite interest
- reframe a failed hire or an off-roadmap request as a new means
- stop exploring and switch back to ordinary planning

## Example prompts
- Work through this new niche with effectuation: inventory my means and give me one step inside my affordable loss
- Run an effectuation brief on my project with means, affordable_loss and next_action
- My plans keep breaking — rework them through effectuation and tell me when to switch to causal planning

# Effectuation

Under Knightian uncertainty, start from available means and affordable loss—not a fixed goal and predicted return. Create the path through controllable action and real commitments.

## When to Use

- The market, technology, or problem is novel enough that outcome probabilities are not trustworthy.
- Means are clearer than the goal: identity, skills, assets, and network exist before a fixed target does.
- A small action can buy information or a partner commitment without risking ruin.
- Plans keep breaking because the environment shifts faster than forecasts.

## When NOT to Use

- The path is predictable: known market, knowable unit economics, established playbook → use causal planning.
- A single wrong step is ruinous or irreversible → de-risk first; do not treat affordable-loss steps as free.
- The goal is already fixed and resources are the only uncertainty → plan to the goal.
- Routine execution with settled requirements → act; do not re-inventory means.

## Procedure

1. **Inventory means only.** List who you are (skills, constraints, values), what you know (domain, tools, data), and who you know (reachable partners, users, resources). Reject "what would be needed for an ideal plan" as input.
2. **Cap affordable loss.** State the maximum time, money, reputation, and opportunity cost you can lose and still continue. If the proposed step exceeds any cap, redesign the step smaller or stop.
3. **Choose one controllable next action.** Prefer the smallest action that can yield either (a) a real commitment from someone else or (b) discriminating information. Act inside the loss cap; do not optimize expected return.
4. **Seek commitments, not opinions.** Share the working means-based offer. Anyone who commits resources, access, or work becomes a co-creator and may reshape the goal. Discard non-committing feedback as non-binding.
5. **Leverage contingencies.** Treat surprises as new means: failed hires, competitor moves, off-roadmap requests. Ask "how can this expand control?" not "how do we restore the old plan?"
