# thinking-systems

A skill for problems that resist local fixes: it maps the system, finds feedback loops and delays, then ranks interventions by leverage.

## What it does

The skill kicks in when a symptom spans several services or components and point fixes do not stick — you patch one place and break another. Instead of hunting the guilty line, it treats the problem as structure and interaction.

The procedure runs in steps. First you bound the system: purpose, actors, in and out flows. Then stocks get listed (queue depth, debt, cache size, WIP) along with the rates that fill and drain them. Next come feedback loops — reinforcing versus balancing, with link signs and delays such as TTL, deploy lag or metric lag. If the problem keeps returning, the skill checks the structure against recurring archetypes: Fixes That Fail, Shifting the Burden, Limits to Growth and others. An archetype is only applied when recurrence is actually present.

Output is a block with boundary, stocks and flows, loops, the structural driver and ranked interventions — from goals and rules down to parameters, each with side-effect risk and watch signals. There is an over-application guard too: if removing one component fully explains and fixes the issue, the skill tells you to drop the map and go back to local debugging. Worth installing once your local fixes have already been tried and failed.

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

2. **Manually: put the files in place**
- File: `.cursor/skills/thinking-systems/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install tjboudreaux/cc-thinking-skills thinking-systems
```

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

gemini skills install https://github.com/tjboudreaux/cc-thinking-skills --path skills/thinking-systems
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/thinking-systems/SKILL.md` — The legacy .windsurf/skills/ path still works

## When to use it
- debug a bug that only shows up across service boundaries
- explain why a fix in one module breaks behaviour in another
- find the reinforcing loop that brings an incident back after every patch
- separate the structural driver from the proximate symptom
- pick the highest-leverage intervention and check its side effects

## Example prompts
- the symptom runs across three services and local fixes keep bouncing — map the system and rank the interventions
- why does the queue refill after every fix? find the loops and delays
- this is the third time it comes back, check the structure against archetypes and name a leverage point

# Systems Mapping and Leverage

Treat the problem as structure and interaction, not isolated parts. Map boundary, stocks/flows, loops/delays, and recurring patterns; intervene at the highest feasible leverage after a side-effect check.

## When to Use

- Symptom spans services/components; single-stack fixes fail or bounce.
- A change in one place breaks another; behavior is emergent.
- Problem recurs despite local fixes (structure, not only symptom).
- Need to rank interventions when parameter/buffer tweaks do not stick.

## When NOT to Use

- Single-component linear bug with clear stack/diff—trace and fix.
- Throughput limited by one obvious stage—use theory-of-constraints.
- Decision is a consequence chain of one proposed action—use second-order.
- Approach selection (plan vs probe vs stabilize)—use cynefin first.

## Procedure

1. **Bound the system.** Name purpose, actors, boundary, and in/out flows. Exclude noise outside the decision horizon; include any path that can feed the symptom.
2. **Map stocks and flows.** List accumulating stocks (queue depth, debt, cache size, WIP) and the rates that fill/drain them. Note what changes slowly even when flows jump.
3. **Find feedback and delays.** For each candidate loop: classify reinforcing (amplifies) vs balancing (resists); mark same-direction (+) vs opposite (-) links; name delays (TTL, deploy lag, metric lag, ramp-up). Even count of opposite links → reinforcing; odd → balancing. Long delay + strong correction → overshoot risk.
4. **Match recurring structure when problems return.** Check only if recurrence or policy resistance is present; do not force a pattern:
   - Fixes That Fail — quick fix, delayed worse side effect
   - Shifting the Burden — workaround starves fundamental fix
   - Limits to Growth — growth hits a balancing constraint
   - Tragedy of the Commons — local optima deplete a shared stock
   - Escalation — mutual reaction spiral
   - Success to the Successful — advantage compounds via allocation
