# plan

Reads the request, open drafts and code, then writes only the documents a later reader will need. A small fix gets none.

## What it does

The `plan` skill from the archcore set takes a topic and decides what is actually worth writing down. It searches `.archcore/` with `mcp__archcore__search_documents` and `mcp__archcore__list_documents`, pulls linked documents one hop through `implements`, `depends_on` and `related` relations, then reads the branch, recent commits and working tree. Document types follow from the request: a new CSV export feature usually means one `spec` and one `plan`; a coordinated HTTP client upgrade across three services means a `plan` alone; a notifications platform adds a `prd` on top.

An existing draft on the topic that carries an `archcore:track` state block gets resumed at its earliest incomplete gate instead of starting a new track. With no `.archcore/` directory at all, the skill announces initialization in one line and calls `mcp__archcore__init_project` without asking anything. Investigation requests route to the `research` type, comparisons to `rnd`, and when the deciding facts are already recorded and only the weights are in dispute, an `rfc` is created.

Know the edges. Recording a decision, documenting existing code and codifying a team standard belong to `/archcore:document`; checking documents against code belongs to `/archcore:review`. The skill leans on the archcore MCP server and the shared files under `skills/_shared/`, so without them the search and routing steps have nothing to run on.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add archcore-ai/archcore --skill plan -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add archcore-ai/archcore --skill plan -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add archcore-ai/archcore --skill plan -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install archcore-ai/archcore plan
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add archcore-ai/archcore --skill plan -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/archcore-ai/archcore --path plugins/archcore/skills/plan
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add archcore-ai/archcore --skill plan -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/archcore-ai/archcore/tree/HEAD/plugins/archcore/skills/plan/SKILL.md

## When to use it
- work out which documents a task needs and which would be noise
- pick up an abandoned planning draft at its last gate
- separate gathering material from weighing alternatives
- trace only the requirement levels an auditor asked for
- gather code and git context before a feature discussion

## Example prompts
- Plan a new feature for CSV export
- Investigate X before we plan
- Compare the alternatives for Y: REST or a queue? Two teams disagree

description: "Plan future work, investigate before building, research a topic, or compare the alternatives for a choice. Takes optional free text. The skill reads the request, open drafts, accepted canon, branch, and code, then creates only the documents a later reader needs — none for a small fix. Use for 'plan the X redesign', 'create a roadmap', 'plan a new feature', 'plan the onboarding journey', 'investigate X before we plan', 'compare the alternatives for Y', 'REST or a queue? two teams disagree', 'I need market research before we plan', 'we are regulated — trace the requirements'. With no arguments it resumes an open planning draft or offers what to plan next. Not for recording a decision or documenting existing code — use /archcore:document. Not for checking docs against code — use /archcore:review."

# /archcore:plan

Plan future work from the project context. Context resolution
(`skills/_shared/gate-contract.md`, section Context resolution) records the
claims, unknowns, hazards, and authority; the conductor
(`skills/_shared/delta-routing.md`) selects the documents a later reader needs;
instruments produce them. Vision types are the primary output. Reads cover all three categories: vision supplies intent and
resumption targets, knowledge supplies constraints, experience supplies
precedent.

## When to use

- "Plan a new feature for CSV export" → typically one `spec` and one `plan`
- "Upgrade the HTTP client across three services with a coordinated rollout" → a `plan` alone
- "Plan the notifications platform" → a `prd`, one `spec` per capability, one `plan`
- "Fix the typo in the onboarding copy" → no document; implement directly
- "I need market research before we plan" → acquisition instrument
- "We must trace these requirements for the auditor" → only the requirement levels that obligation names
- "Investigate X before we plan" → `research`; "Compare the alternatives for Y" → `rnd`
- "REST or a queue for SAP? Two teams disagree", with the facts of both options recorded → `rfc`
- `research <topic>` as the first word → the type `research`

**Not plan:**

- Recording a decision → `/archcore:document`
- Documenting existing code → `/archcore:document`
- Codifying a team standard → `/archcore:document`
- Checking documents against code → `/archcore:review`
