T3d init

t3d-init

Copy the harness templates into the current project root (the directory where Claude Code was launched).

Plan

1. Resolve the project root from ${CLAUDE_PROJECT_DIR}. Print it.
2. For each template file under ${CLAUDE_PLUGIN_ROOT}/templates/:
   • Compute destination path under ${CLAUDE_PROJECT_DIR}/.
   • If destination exists, ask the user before overwriting (do NOT silently clobber CLAUDE.md).
   • Otherwise, cp it across, preserving directory structure.
3. After copying, print a "next steps" message:
   • Open CLAUDE.md and fill the <!-- FILL IN --> project-identity section.
   • Open CONTEXT-MAP.md and list your bounded contexts.
   • Run /t3d-new-context <your-first-context> to scaffold the first context.

Required tool calls

You must use the Bash tool to run cp -r. Do not use the Write tool for copying — it would re-author files and lose timestamps/perms.

Templates to copy

The plugin ships this layout under ${CLAUDE_PLUGIN_ROOT}/templates/:

templates/
├── CLAUDE.md                # generic harness rules (with FILL IN placeholders)
├── CONTEXT-MAP.md           # empty bounded-context inventory
├── contexts/
│   ├── _TEMPLATE/           # 4-layer skeleton — copy-paste source for new contexts
│   └── _shared_kernel/      # example pure value objects (Money, Timestamp, ModelName, TokenCount)
└── docs/
    └── adr/
        ├── README.md        # Matt Pocock 3-condition ADR rule
        └── NNNN-template.md # ADR template

Conflict handling

If ${CLAUDE_PROJECT_DIR}/CLAUDE.md already exists, ask the user one of:

• keep — leave existing, don't copy CLAUDE.md (default)
• overwrite — replace with plugin version
• view-diff — show diff first

Do not overwrite contexts/_shared_kernel/ if it exists either — that directory often has project-specific value objects.

Done criteria

After running, the user should be able to:

• Edit a file at contexts/anything/domain/x.py containing import fastapi and see the PreToolUse hook DENY it.
• Run /t3d-new-context billing and see contexts/billing/ appear with the full 4-layer skeleton.
