+description: "Document-based project control for AI-human collaboration. Use '/doc-harness init' to create a status documentation system for any project (new or existing), or '/doc-harness check' to audit documentation health and reflect on working principles. Keeps projects organized, principles enforced, and information persistent across context resets."

+
+# Doc Harness — Document-Based Project Control
+
+Doc Harness creates and maintains a structured documentation system for any project, enabling any AI agent or human collaborator to understand and resume project work purely from reading files — no external memory needed.
+
+**Repository with full documentation, templates, and Chinese version**: https://github.com/cilidinezy-commits/doc-harness
+
+## Commands
+
+### `/doc-harness init [project-name] [description]`
+
+Creates 5 documents in the current directory:
+
+| Document | Role |
+|----------|------|
+| **CLAUDE.md** | Project entry point — overview, recovery chain, iron rules, embedded operational rules |
+| **CURRENT_STATUS.md** | Active state — recent history, current work detail, next steps, working principles |
+| **FILE_INDEX.md** | File catalog organized by category |
+| **WORKLOG.md** | Permanent work history (append-only) |
+| **DOC_HARNESS_SPEC.md** | Complete specification (reference) |
+
+**How to use**: Just say "set up project documentation" or "create a status doc system for this project." The agent will ask about your project and create tailored documents. Works for new projects and projects already in progress.
+
+**Information gathering**: Extract project details from conversation context first. For anything unclear, ask the user — don't guess. Required: project name, description, first phase name, first task.
+
+### `/doc-harness check`
+
+Runs a two-part audit:
+
+**Part 1 — File Health**: Checks all 4 core documents exist, CURRENT_STATUS is fresh, FILE_INDEX matches actual files on disk, WORKLOG TOC is consistent, car body isn't too long.
+
+**Part 2 — Principle Reflection**: Reads the project's iron rules and working principles, prompts honest reflection: "Am I following these?" Includes a "Write It Down" check for unsaved information.
+
+**How to use**: Just say "check the status documentation" or "run a doc-harness check in the background."
+
+## Core Principle: "Write It Down or Lose It"
+
+All information in context is temporary. Important information must be **written to a file** and **registered in FILE_INDEX**. Not written = lost. Not registered = undiscoverable = effectively lost.
+
+## CURRENT_STATUS Structure ("Moving Car")
+
+| Section | What's in it |
+|---------|-------------|
+| **Recent History** (Tire Tracks) | 2-3 summaries of recently completed phases |
+| **Current Phase Detail** (Car Body) | Full record of active work — steps, files, decisions |
+| **Next Steps** (Headlights) | Immediate actions + future plans |
+| **Phase Principles** (Driving Manual) | Working guidelines for this phase |
+
+When a phase ends: car body → archived to WORKLOG, compressed to tire track summary, cleared for new phase.
+
+## Key Rules for Agents
+
+**Session start**: Read CLAUDE.md → CURRENT_STATUS → continue working.
+
+**During work**:
+- Complete a meaningful step → update CURRENT_STATUS car body
+- Create a file → register in FILE_INDEX + record in CURRENT_STATUS
+- Important insight or decision → save to file immediately (Write It Down!)
+
+**Session end checklist**:
+- [ ] CURRENT_STATUS car body reflects all work?
+- [ ] Next steps accurate?
+- [ ] Dates refreshed?
+- [ ] New files registered in FILE_INDEX?
+- [ ] Anything unsaved in context? → Write it down!
+
+**Phase transition** (5 steps, strictly in order):
+1. Copy car body to WORKLOG (protect data first)
+2. Compress to tire track summary in CURRENT_STATUS
+3. Remove oldest tire track if >3
+4. Clear car body for new phase; update driving manual
+5. Update CLAUDE.md status; update WORKLOG TOC
