## What it does

The skill tracks progress through structured project decisions: `set_target`, `start_experiment` paired with `commit_to_build`, `release`, and `close`. For L0 scale, it handles `state_purpose` and `review`. Closing a diamond triggers an executable Definition of Done checklist that serves as an active transition gate.

Before running any gate checks, the workflow enforces cognitive forcing. It asks for your unprimed gut assessment first, records it, and then compares your instinct against formal gate results. Canvas modifications under `.claude/canvas/*.yml` enforce strict preflight rules: you must execute the `Read` tool before any `Write` or `Edit`, and prefix sequence IDs require numeric scanning to prevent duplicates.

Running this skill standalone bypasses the underlying theory gates, harness behavior, and canvas state tracking. It depends directly on the Mycelium framework to function properly.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add haabe/mycelium --skill diamond-progress -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add haabe/mycelium --skill diamond-progress -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add haabe/mycelium --skill diamond-progress -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install haabe/mycelium diamond-progress
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add haabe/mycelium --skill diamond-progress -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/haabe/mycelium --path plugins/mycelium/skills/diamond-progress
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add haabe/mycelium --skill diamond-progress -a opencode
```

### Claude.ai

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

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/haabe/mycelium/tree/HEAD/plugins/mycelium/skills/diamond-progress/SKILL.md

## When to use it
- record stage decisions like `set_target`, `commit_to_build`, or `close`
- evaluate theory gates before advancing project state in canvas files
- verify numeric ID sequences in `.claude/canvas/*.yml` to avoid duplicates
- compare developer gut judgment against formal Definition of Done criteria

## Example prompts
- Record the commit_to_build decision for the active diamond
- Run the theory gates and record close on this diamond
- Advance the canvas state with set_target

# Diamond Progress Skill

Record a diamond's decisions, each through the theory gates it needs. Where a diamond is, is read from its decisions ("target set", "committed to build", "released", "closed"; discovery until `commit_to_build`, delivery after; DL-1368, DL-1372). At `close`, runs an executable checklist that GATES it.

## Preflight: Read target canvas file(s) before any Write/Edit

**Hard rule.** Before issuing `Write` or `Edit` against any `.claude/canvas/*.yml`, use the **Read tool** on that file in this session. Claude Code's Read-before-Write check requires the `Read` tool specifically — `cat`/`head`/`grep` via Bash do NOT satisfy it.

## Preflight: Read-before-Recommend (gate-narration discipline)

**Hard rule** (per the operating contract's Communication Rules, anti-pattern #7 graduation v0.39.16). Every gate-status narration, blocker statement, hold claim, theory-gate verdict, or transition-blocked finding this skill emits MUST cite the canvas file + field path of the source evidence. Adjacent-surface inference (different opportunity, different ht, different topic) MUST be tagged as inference, not asserted as gate state. Companion to the Read-before-Write rule above: that one protects what gets WRITTEN to canvas; this one protects what gets CLAIMED about canvas state in the skill's narration.

**Edit vs Write — different cost profiles** (verified 2026-05-14):
- **`Edit`** (exact-string replacement): `Read` with `limit: 1` satisfies the check at ~50 tokens. State-tracking is per-file, not per-byte — subsequent `Edit` calls work anywhere in the file. Use this for partial updates against large canvas files (e.g., `purpose.yml` at 800+ lines).
- **`Write`** (full replacement): do a **full Read** first. Write obliterates the file; you should see what you're about to replace. The `limit:1` shortcut is *not* appropriate here.

**ID-bearing entries — scan the ID space before assigning** (added 2026-05-15, v0.23.19): When adding a new component, opportunity, solution, or any other ID-bearing entry to a canvas file, run a Bash grep first to confirm the next ID in your prefix sequence is actually free:
