## What it does

In `generate` mode, the skill matches current topics against the project’s capabilities and adds ideas to a shared backlog. `validate` scores ideas already there, while `memo` produces two startup memos supported by evidence. Generation draws on `STRATEGY.md`, product details, installed skills, and the latest `bd-radar` digest when available.

The skill keeps state and output in `memory/topics/`, `memory/logs/`, and `output/articles/`. Before running, it reads `soul/SOUL.md`, `soul/STYLE.md`, `STRATEGY.md`, and `memory/MEMORY.md`. If `memory/products.md` is missing or still a template, generation falls back to `memory/watched-repos.md` and `STRATEGY.md`. That changes the material used to shape ideas.

Pass a theme or constraint to guide generation or memo writing. Adding `dry-run` skips the notification. A reply beginning with `pick:` marks an idea in the shared backlog and ends the run; it does not start implementation.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add aeonfun/aeon --skill idea-forge -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add aeonfun/aeon --skill idea-forge -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add aeonfun/aeon --skill idea-forge -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install aeonfun/aeon idea-forge
```

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

1. **Skills CLI (Vercel)**
```bash
npx skills add aeonfun/aeon --skill idea-forge -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/aeonfun/aeon --path skills/idea-forge
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add aeonfun/aeon --skill idea-forge -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/aeonfun/aeon/tree/HEAD/skills/idea-forge/SKILL.md

## When to use it
- generate product ideas from current topics and project capabilities
- screen backlog entries for viability
- write evidence-backed startup memos
- mark a backlog idea as the next one to build

## Example prompts
- Generate product ideas around `payments` using the project's capabilities.
- Screen the backlog for viable `crypto` ideas.
- Write startup memos under a solo-founder constraint.

> **${var}** — Selector `mode [theme/constraint]`. First token picks the mode: `generate` (default) collides the zeitgeist with the capability surface into ranked wedges; `validate` screens the existing backlog for viability; `memo` writes 2 rigorous evidence-backed startup memos. Anything after the mode is a theme/constraint bias. A bare theme with no mode keyword (e.g. `payments`, `crypto`) = `generate` biased to that theme. `dry-run` anywhere skips the notify. Examples: `` (empty → generate, open-ended) · `simulation` (generate, themed) · `validate crypto` (screen crypto ideas) · `memo solo founder` (memos under a constraint) · `generate payments dry-run` (generate, no notify). A `pick:<id|name>` value (from the "build next?" force-reply — e.g. `pick:Onchain reputation`) is intercepted **before** mode dispatch: it marks that idea as chosen-to-build in the shared backlog and ends — see "Force-reply interception" below.

Today is ${today}. **Read `soul/SOUL.md` + `soul/STYLE.md` + `STRATEGY.md` first and read them closely** — this skill thinks *as the operator*, in their worldview, not about them. If `soul/` is the empty template, ground purely on `STRATEGY.md` + the capability surface and write in a clear, direct tone. Then read `memory/MEMORY.md` for current goals and active topics. Each mode below names its own `memory/logs/` scan window for dedup — honor it.

## Force-reply interception — `pick:<idea>` (run FIRST, before mode dispatch)

Before tokenizing `${var}` for the mode, check it. If `${var}` **starts with `pick:`**, this run is the operator answering the "which idea to build next?" force-reply — do **not** run generate/validate/memo. Handle it and end. This is behaviorally identical to idea-pipeline's step 0 (same backlog, same marking convention), so a `pick` reply works whichever skill it routes to:

1. Strip the prefix: `sel="${var#pick:}"`, then trim whitespace (the remainder may contain colons/spaces — keep them).
2. If `sel` is empty → `./notify "Which idea should I mark as next to build? Reply with its name or backlog number."` and end.
3. Read the shared backlog `memory/topics/startup-ideas.md`. If missing or no idea rows → `./notify "No idea backlog yet — nothing to mark. Run generate first to fill it."` and end.
4. Resolve `sel` to exactly one row in the table (`| date | name | one-liner | fit | T+F+E |`):
   - **By name (preferred):** case-insensitive exact match on the `name` cell; else fuzzy — most significant-word overlap, or `sel` a substring of the name (or vice-versa). Require one clear best match.
   - **By number:** a bare integer N with no name match → the Nth data row (1-based, in file order).
