# mold

mold turns a high-stakes design choice into a checked specification through guided dialogue. Use it before architectural or destructive changes.

## What it does

The skill frames the goal, separates settled points from open forks, and selects a dialogue mode such as Explore, Ground, Shape, Sketch, Grill, or Diagnose. It checks claims against code and project evidence, defines module boundaries, and records the decisions that shape the specification.

Its procedure has Quick, Light, and Full tiers, reference material under `references/`, coherence checks, and strict spec validation. The durable artifact path comes from `python3 skills/mold/scripts/mold.pyz artifact-path specs <slug>`. Once the draft is reconciled, mold can offer a handoff to Cook.

The `taste-test` check requires `python3`; without it, `python3 skills/mold/scripts/mold.pyz taste-test` cannot run. `/culture`, `/cook`, and `/briesearch` cover free-form discussion, direct implementation, and research-only questions respectively.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add paulnsorensen/easy-cheese --skill mold -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add paulnsorensen/easy-cheese --skill mold -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add paulnsorensen/easy-cheese --skill mold -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install paulnsorensen/easy-cheese mold
```

2. **Manually: put the files in place**
- File: `.github/skills/mold/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add paulnsorensen/easy-cheese --skill mold -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/paulnsorensen/easy-cheese --path skills/mold
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add paulnsorensen/easy-cheese --skill mold -a opencode
```

### Claude.ai

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

## When to use it
- turn a risky design choice into a written spec
- check the impact of authentication or irreversible operations
- settle a new public interface
- map dependencies across modules
- save a validated spec for Cook

## Example prompts
- Run `/mold` and help me design authentication for this project.
- Shape the API for a new public interface, then test the unresolved design forks.
- Use `/mold` to work through an irreversible operation and save the resulting specification.

name: mold
description: Turn a high-leverage design decision into a validated spec through grounded dialogue. Use it when a leverage trigger fires (auth, irreversible effects, concurrency, contracts, destructive ops, a new slice, a cross-slice dependency, an invariant gap) or when the user asks for a spec or design. Typical phrases include "let's design X", "shape this into a spec", "what should the API for Z look like", and "/mold". A feature ask with zero fired triggers is a `/cook` mini-spec, not a mold; route it through `/cheese`. Do NOT use it for free-form discussion without artifact intent (`/culture`), direct implementation (`/cook`), or research-only questions (`/briesearch`). Ceremony scales to the ask through `references/tiers.md`, so a small clear change gets a validated mini-spec without a write-approval turn.

# /mold

Ceremony scales to the job. The Bounds pass picks one of three tiers from `references/tiers.md`: **Quick** writes a validated mini-spec, **Light** runs only the dialogue modes the open forks need, and **Full** runs the whole Flow below. Saving a spec needs no extraction approval. Cook still needs an explicit user request. `/cheese`'s tier-1 escalation enters mini-spec mode; see `## Agent-invoked mini-spec mode`.

## Flow

1. **Bounds pass** — open the `Goal / Decided / Asking / [AGENT-DECIDED]` ledger with the goal pinned as one sentence; only an explicit user fork changes it. Split it into `G-n` clauses (`references/handshake.md` § Goal coverage). Map every input's goals and **non-goals** as one `[AGENT-DECIDED]` line; ask the user only when the goal is genuinely unknown or a leverage trigger fires. Run the shape check, then announce the tier with its reason (`references/tiers.md`). Quick exits here to `## Agent-invoked mini-spec mode` without a write-approval turn. Upgrade the tier whenever the evidence changes; never downgrade silently.
2. **Route** — choose the secondary mode from `references/modes.md`, announce it, and correct false premises first.
3. **Dialogue** — consequential forks are the user's to pick. A fork is consequential per the leverage line in `../age/references/voice.md`. Every other fork is `[AGENT-DECIDED]`. Supply options, trade-offs, and evidence before you ask. Ground each critical claim through code, the [Validate Cycle](references/validate-cycle.md), or a [Prototype Cycle](references/prototype-cycle.md). Resolve every contradiction. Render the decision map after three consecutive fork questions, or on request.
4. **Sketch** — For work across modules or with a new public interface, run `references/shape-check.md`. Bind identity and role nouns to code referents. Record the Placement block; no bodies.
