+
+</div>
+
+---
+
+Tandem is a Claude Code plugin that takes you from idea to production — without the chaos. You drive the whole plan with slash commands; Tandem makes sure nothing slips: no stories go in-progress without a testplan, no work ships without passing its gates, no decision disappears into the chat log. The result is a team-quality delivery rhythm, at solo-founder pace.
+
+---
+
+## How it works
+
+Tandem installs a `_00-Project-Management/` scaffold into your project and registers a set of `/Tandem:*` skills that cover the full North Star → Done lifecycle. Two hooks keep everything honest: a linter that runs on every PM file edit, and a generator that rebuilds an interactive HTML **Command Center** whenever your plan changes. Both hooks run a single stdlib-only Node entrypoint (`node ${CLAUDE_PLUGIN_ROOT}/_00-Project-Management/93-Scripts/hook.js`) directly — no `npm` step is involved.
+
+It's **stack-agnostic** — the bootstrap asks what you're building (web, mobile, CLI, library, backend, data-pipeline, Power Platform, or automation) and tailors the guidance to match.
+
+### Why it's different from "AI project management"
+
+Most "AI project management" is a chat log. Tandem is a contract:
+
+- **Closed-set status enum** — exactly nine statuses, never invented ad-hoc, so every board reads the same.
+- **Story ↔ Testplan pairing (enforced)** — you cannot create a Story without a paired Testplan where every acceptance criterion maps to a runnable test case. No "trust me, it works."
+- **DoR / DoD gates** — work can't enter *in-progress* without meeting Definition of Ready, and can't reach *done* without Definition of Done. The gates are checked, not assumed.
+- **ADR-on-the-spot** — every non-obvious decision becomes an Architecture Decision Record in the same edit, so the *why* is never lost.
+- **Auto bug-raising** — the moment a test case fails, a structured BUG file is filed before the failure is even reported back to you.
+- **A living Command Center** — a single self-contained HTML view of your entire plan, regenerated automatically. (That's the [live demo](https://data-ai-xyz.github.io/Tandem/) above.)
+
+## The lifecycle
+
+```mermaid
+flowchart LR
+  NS[North Star] --> OKR[OKRs]
+  OKR --> PRD[PRD]
+  PRD --> E[Epic]
+  E --> F[Feature]
+  F --> S[Story]
+  S --> TP[Testplan]
+  TP --> X[execute-story]
+  X --> R[run-testplan]
+  R --> C[close-out-story]
+  C --> M[(Command Center)]
+  M -. weekly / monthly review .-> OKR
+```
+
+Every arrow is a slash command. Every box is a markdown artefact in your repo.
+
+## Install
+
+```bash
+# 1. Add the Tandem marketplace
+/plugin marketplace add DATA-AI-XYZ/Tandem
+
+# 2. Install the plugin
+/plugin install Tandem@DATA-AI-XYZ
+
+# 3. Bootstrap it into your project (drops _00-Project-Management/, wires hooks, seeds CLAUDE.md)
+/Tandem:session-start
+```
+
+On install Tandem will:
+
+1. Drop the `_00-Project-Management/` scaffold into your project root (if absent).
+2. Register the `/Tandem:*` skills covering the full North Star → Done lifecycle.
+3. Enable two hooks — lint-on-edit and Command-Center-regen-on-stop.
+4. Insert a slim PM rules block into your root `CLAUDE.md` (idempotent, under a managed marker).
+
+> No plugin access? Tandem also ships a paste-prompt installer — see [`BOOTSTRAP-PROMPT.md`](BOOTSTRAP-PROMPT.md).
+
+## Slash commands
+
+| Command | Hat | When to use |
+|---|---|---|
+| `/Tandem:session-start` | any | Orient at the start of a session: read active work, recent ADRs, the board; announce the next step |
+| `/Tandem:draft-okrs` | Founder | Draft quarterly OKRs from a North Star |
+| `/Tandem:draft-prd` | Founder→PM | Draft a PRD from an OKR or raw notes |
+| `/Tandem:draft-epic` | PM | Draft an Epic from an OKR key result or PRD section |
+| `/Tandem:split-into-features` | PM | Decompose an Epic into Features |
+| `/Tandem:split-into-stories` | PM | Decompose a Feature into Stories + paired Testplans |
+| `/Tandem:refine-backlog` | PM | DoR gate — promote to *ready* or list the gaps; never silently promotes |
+| `/Tandem:execution-strategist` | PM | Plan how to execute an Epic — group stories into batches with lanes & sub-agents |
+| `/Tandem:execute-story` | Dev | Pull a *ready* Story into active work |
+| `/Tandem:execute-batch` | Dev | Run a whole strategy "batch" of stories end-to-end |
+| `/Tandem:run-testplan` | QA | Run every test case; auto-file BUGs on failure |
+| `/Tandem:close-out-story` | QA→PM | DoD gate (incl. AI-code review) + board update |
+| `/Tandem:weekly-monitor` | PM | Friday weekly summary; flag stalls and blocks |
+| `/Tandem:monthly-retro` | Founder/PM | Monthly retrospective |
+| `/Tandem:fill-claude-md` | any | Author/refresh `CLAUDE.md` files across the codebase |
+| `/Tandem:reflect` | any | End-of-session reflection: propose improvements (you approve before applying) |
+| `/Tandem:core` | — | Force-load the core PM rules (usually auto-loaded) |
+
+Skills are model-invoked — Claude auto-loads them when your task matches — but explicit invocation always works.
+
+## The Command Center
+
+The headline feature. A single self-contained HTML file, regenerated from your markdown plan, with tabs for the plan tree, the monitor board, the execution strategy, and a glossary. It's built to be glanceable and stays current automatically (the Stop hook regenerates it whenever a PM file changes).
