# 📝 Description
[//]: #@corifeus-header:end
A multi-agent **RUP** (Rational Unified Process) pipeline for software design — driven by your **Claude Code + ChatGPT subscriptions** (no API keys, no per-call cost).
You hand it a one-paragraph requirement from a stakeholder. It hands you back a complete design dossier and a working implementation under `agents/<slug>/` — produced by **eleven role-played AI agents** that alternate between OpenAI (via `codex` CLI) and Claude (via `claude` CLI) across the four classic RUP phases:
| Phase | Roles | Provider chain |
| --- | --- | --- |
| **1. Inception** | `vision`, `vision-reviewer` | OpenAI → Claude |
| **2. Elaboration** | `requirements-analyst`, `architect`, `risk-analyst`, `design-reviewer` | OpenAI → Claude → OpenAI → Claude |
| **3. Construction** | `implementer`, `critic` ↔ `reviser` (loop) | Claude, then OpenAI ↔ Claude |
| **4. Transition** | `acceptance-writer`, `deployment-writer` | OpenAI → Claude |
Each phase's outputs feed the next. The cross-provider chain catches blind spots a single model would miss — when OpenAI writes the requirements, Claude reviews them; when Claude writes the architecture, OpenAI flags the risks; when Claude implements, OpenAI critiques.

## Cheapest path: subscriptions, not API keys
`p3x-architect` does **not** call the OpenAI or Anthropic HTTP APIs. It spawns the **`claude` CLI** (your Claude Code subscription) and the **`codex` CLI** (your ChatGPT subscription) as subprocesses and uses their structured-output flags (`--json-schema` for claude, `--output-schema` for codex).
This is **deliberate, and it's the whole point**:
- A single API run with `gpt-5.5` ($5 / $30 per 1M tok) + `claude-opus-4-7` ($15 / $75 per 1M tok) costs **$2–$10**. Ten runs a month → $20–$100 in API bills.
- A Claude Pro subscription is ~$20/month flat. ChatGPT Plus is ~$20/month flat. **You already pay for these.** Running the architect against them is **$0 marginal cost.**
- Trade-off: the CLI route is slower (5–15s per role × 11 roles = 1–3 min per pipeline run) and the model is whatever your subscription tier gives you. For the "boss handed me a feature, lay it out" use case, that's fine.
### Prerequisites — install both CLIs and log in once
#### 1. `claude` (Claude Code) — your Anthropic subscription
Both ship as Node packages, so install is the same on **Linux, macOS, and Windows** (anywhere Node.js ≥ 18 runs):
```bash
npm install -g @anthropic-ai/claude-code
# or, on macOS/Linux: curl -fsSL https://claude.ai/install.sh | bash
```
Then run `claude` once interactively — it opens a browser to OAuth into your **Claude Pro / Max** subscription. After that, `claude --print` works headlessly without prompts.
#### 2. `codex` (Codex CLI) — your ChatGPT subscription
```bash
npm install -g @openai/codex
# or, on macOS: brew install codex
# or grab a release binary from https://github.com/openai/codex/releases
```
Then run `codex login` once — opens a browser to attach your **ChatGPT Plus / Pro** subscription. After that, `codex exec` works headlessly without prompts.
> Both CLIs put their auth in your home directory (`~/.claude/`, `~/.codex/`), so once you've logged in any subprocess spawned by `p3x-architect` picks it up.
#### 3. `p3x-architect` itself
```bash
yarn global add p3x-architect
# or
npm install -g p3x-architect
```
If you don't want a global install, the MCP entry works on-demand via `npx -y -p p3x-architect p3x-architect-mcp` — `npx` pulls the `p3x-architect` package and runs its `p3x-architect-mcp` bin. **There is no separate `p3x-architect-mcp` package on npm**; both binaries ship inside `p3x-architect`.
### Model selection
Models are picked automatically by the CLIs: `claude` defaults to `opus`, `codex` picks the highest model your account is entitled to (`gpt-5.5` as of 2026-04). To override:
```bash
ANTHROPIC_MODEL=sonnet # opus | sonnet | haiku
CODEX_MODEL=gpt-5.5 # only set if you need to force a specific codex model
```
### What if you'd rather use API keys?
You can't, in this version. The HTTP-API providers were removed in favor of the CLI subprocess approach. If that ever needs to come back, it would land behind a flag (e.g. `--via-api`) — but no plans to do so.
## CLI usage
From the project where you want the `agents/<slug>/` folder created:
```bash
# from a Markdown spec
p3x-architect docs/feature-x.md --name feature-x
# inline text
p3x-architect --text "Build a simple REST API for tasks with create/list/update/delete and a SQLite store" --name task-api
# pipe via stdin
cat requirement.md | p3x-architect --name nightly-report
# tighten budget and rounds
p3x-architect spec.md --name auth --budget 3 --max-rounds 1
```
All flags:
| Flag | Purpose |
| --- | --- |
| `[input]` | path to a Markdown file containing the requirement |
| `-t, --text <s>` | inline requirement (alternative to a file) |
| `-n, --name <slug>` | folder name under `agents/` (auto-derived if omitted) |
| `-o, --output <dir>` | override output directory |
| `-r, --max-rounds <n>` | maximum critic↔reviser rounds (default `2`) |
| `-b, --budget <usd>` | cumulative USD budget across all roles (default `5`, `0` = unlimited) |
| `--cwd <dir>` | project root for `agents/<slug>/` (defaults to `process.cwd()`) |
## MCP usage (Claude Code, Cursor, VS Code, …)
The `p3x-architect` package ships **two binaries**:
| Binary | Purpose |
| --- | --- |
| `p3x-architect` | the CLI you saw above |
| `p3x-architect-mcp` | a Model Context Protocol server (stdio) that exposes the pipeline as a single `architect` tool |
Both live in the same package — there is no separate `p3x-architect-mcp` package. Wherever the docs below say `npx -y -p p3x-architect p3x-architect-mcp`, the `-p` flag tells `npx` "install the `p3x-architect` package, then run the `p3x-architect-mcp` bin from it."
### Claude Code (terminal **or** VS Code extension)
The Anthropic `claude` CLI and the **Claude Code VS Code extension** share the same MCP registry (`~/.claude.json`), so a single `claude mcp add` invocation registers the server for both. Run it once from any terminal:
```bash
# global install — short form
yarn global add p3x-architect
claude mcp add p3x-architect -- p3x-architect-mcp
# no global install — npx runs it on demand
claude mcp add p3x-architect -- npx -y -p p3x-architect p3x-architect-mcp
# per-workspace registration (lives in .mcp.json next to your project, scoped to that repo)
claude mcp add --scope project p3x-architect -- npx -y -p p3x-architect p3x-architect-mcp
```
Restart the Claude Code panel in VS Code (or re-open the chat in the terminal) and the `architect` tool will appear in the tool list. Then ask: *"Use p3x-architect to plan and implement this feature: …"*
### VS Code native MCP (no Claude Code extension)
VS Code 1.95+ ships native MCP support for any MCP-aware extension. Add the file `.vscode/mcp.json` at your workspace root:
```json
{
"servers": {
"p3x-architect": {
"command": "npx",
"args": ["-y", "-p", "p3x-architect", "p3x-architect-mcp"]
}
}
}
```
### Generic MCP clients (Cursor, Continue, Zed, …)
```json
{
"mcpServers": {
"p3x-architect": {
"command": "npx",
"args": ["-y", "-p", "p3x-architect", "p3x-architect-mcp"]
}
}
}
```
### Local (unpublished) testing
If you cloned this repo and want to drive the MCP from VS Code Claude Code without publishing first, point at the local bin directly:
```bash
claude mcp add p3x-architect -- node /absolute/path/to/architect/bin/architect-mcp.js
```
The MCP exposes one tool — `architect` — with these parameters:
- `requirement` (required) — plain-language requirement
- `slug` (optional) — folder under `agents/`
- `project_root` (optional) — absolute path; defaults to MCP server cwd
- `max_rounds` (optional) — defaults to 2
- `budget_usd` (optional) — defaults to `ARCHITECT_BUDGET_USD` or 5
The tool blocks for 30–120 seconds while the pipeline runs. Returns a JSON summary with the verdict, file count, total cost, and per-role token usage.
## Cost & timing
Because every role spawns your local `claude` / `codex` CLI, **runtime cost is $0** beyond your existing subscriptions. The `--budget` flag and `usd` fields in `pipeline.json` are kept for forward compatibility with an API-mode that may return later — they will all read `0` in CLI mode.
Wall-clock time is dominated by `claude` startup (each invocation re-loads its tooling) plus inference latency. Expect:
- 5–15 seconds per role
- 1–3 minutes for the full 11-role pipeline on a small spec
- 3–6 minutes on a large one with two critic↔reviser rounds
You can dial down latency with:
- `ANTHROPIC_MODEL=sonnet` (faster than opus, still strong)
- `--max-rounds 1` (skip the second critic round)

## Programmatic API
```js
import { architect } from 'p3x-architect';
const result = await architect({
requirement: 'Build a CRUD task API in Node.js with SQLite',
slug: 'task-api',
projectRoot: process.cwd(),
maxRounds: 2,
budgetUsd: 5,
log: console.log,
});
console.log(result.verdict); // ready-to-build | fix-then-build | redesign
console.log(result.files.length);
console.log(result.usage.totalUsd);
```
Every role is also exported individually if you want to run a single phase.
