## Path Patterns (MANDATORY)

### Plugin Paths

| Context | Pattern | Example |
|---------|---------|---------|
| Plugin location | `plugins/{plugin-name}/` | `plugins/projman/` |
| Plugin manifest | `plugins/{plugin-name}/.claude-plugin/plugin.json` | `plugins/projman/.claude-plugin/plugin.json` |
| Plugin commands | `plugins/{plugin-name}/commands/` | `plugins/projman/commands/` |
| Plugin agents | `plugins/{plugin-name}/agents/` | `plugins/projman/agents/` |
| Plugin .mcp.json | `plugins/{plugin-name}/.mcp.json` | `plugins/projman/.mcp.json` |
| Plugin integration snippet | `plugins/{plugin-name}/claude-md-integration.md` | `plugins/projman/claude-md-integration.md` |

### MCP Server Paths (v3.0.0 Architecture)

MCP servers are **shared at repository root** with **symlinks** from plugins.

| Context | Pattern | Example |
|---------|---------|---------|
| Shared MCP server | `mcp-servers/{server}/` | `mcp-servers/gitea/` |
| MCP server code | `mcp-servers/{server}/mcp_server/` | `mcp-servers/gitea/mcp_server/` |
| MCP venv | `mcp-servers/{server}/.venv/` | `mcp-servers/gitea/.venv/` |
| Plugin symlink | `plugins/{plugin}/mcp-servers/{server}` | `plugins/projman/mcp-servers/gitea` |

### Symlink Pattern

Plugins that use MCP servers create symlinks:
```bash
# From plugin directory
ln -s ../../../mcp-servers/gitea plugins/projman/mcp-servers/gitea
```

The symlink target is relative: `../../../mcp-servers/{server}`

### Documentation Paths

| Type | Location |
|------|----------|
| Architecture diagrams | `docs/architecture/` |
| This file | `docs/CANONICAL-PATHS.md` |
| Update guide | `docs/UPDATING.md` |
| Configuration guide | `docs/CONFIGURATION.md` |
| Commands cheat sheet | `docs/COMMANDS-CHEATSHEET.md` |
| Debugging checklist | `docs/DEBUGGING-CHECKLIST.md` |

## Validation Rules

### Before Creating Any File

1. Check this file for the correct path pattern
2. Verify the parent directory exists in the structure above
3. If path not listed here, **STOP AND ASK**

### Before Generating Any Prompt

1. List all file paths the prompt will create/modify
2. Verify each path against patterns in this file
3. Show verification to user before proceeding

### Relative Path Calculation (v3.0.0)

From `plugins/projman/.mcp.json` to shared `mcp-servers/gitea/`:
```
plugins/projman/.mcp.json
  → Uses ${CLAUDE_PLUGIN_ROOT}/mcp-servers/gitea/
  → Symlink at plugins/projman/mcp-servers/gitea points to ../../../mcp-servers/gitea

Result in .mcp.json: ${CLAUDE_PLUGIN_ROOT}/mcp-servers/gitea/.venv/bin/python
```

From `.claude-plugin/marketplace.json` to `plugins/projman/`:
```
.claude-plugin/marketplace.json
  ↑ marketplace.json is at repo root level
  → go down to plugins/projman/           (./plugins/projman/)

Result: ./plugins/projman
```

---

## Anti-Patterns (NEVER DO THIS)

| Wrong | Why | Correct |
|-------|-----|---------|
| `projman/` at root | Plugins go in `plugins/` | `plugins/projman/` |
| Direct path in .mcp.json to root mcp-servers | Use symlink | Symlink at `plugins/{plugin}/mcp-servers/` |
| Creating new mcp-servers inside plugins | Use shared + symlink | Symlink to `mcp-servers/` |
| Hardcoding absolute paths | Breaks portability | Use `${CLAUDE_PLUGIN_ROOT}` |

---

## Architecture Note (v3.0.0)

MCP servers are now **shared at repository root** with **symlinks** from plugins:

**Benefits:**
- Single source of truth for each MCP server
- Updates apply to all plugins automatically
- Reduced duplication
- Symlinks work with Claude Code caching

**Symlink Pattern:**
```
plugins/projman/mcp-servers/gitea -> ../../../mcp-servers/gitea
plugins/cmdb-assistant/mcp-servers/netbox -> ../../../mcp-servers/netbox
plugins/pr-review/mcp-servers/gitea -> ../../../mcp-servers/gitea
plugins/data-platform/mcp-servers/data-platform -> ../../../mcp-servers/data-platform
plugins/viz-platform/mcp-servers/viz-platform -> ../../../mcp-servers/viz-platform
plugins/contract-validator/mcp-servers/contract-validator -> ../../../mcp-servers/contract-validator
```
