Steve Yegge 39a58fd085 docs: document bd setup command
Add comprehensive documentation for the bd setup command which was
largely undocumented (GH#518):

- CLI_REFERENCE.md: Add new "Editor Integration" section documenting
  bd setup claude/cursor/aider commands with all flags
- INSTALLING.md: Fix incorrect reference to "bd hooks install" for
  editor integration - should be "bd setup <editor>"
- CLAUDE_INTEGRATION.md: Add Installation section with bd setup claude
  examples

Fixes: GH#518

# Claude Code Integration Design
This document explains design decisions for Claude Code integration in beads.
## Integration Approach
**Recommended: CLI + Hooks** - Beads uses a simple, universal approach to Claude Code integration:
- `bd prime` command for context injection (~1-2k tokens)
- Hooks (SessionStart/PreCompact) for automatic context refresh
- Direct CLI commands with `--json` flags
- Optional: Plugin for slash commands and enhanced UX
**Alternative: MCP Server** - For MCP-only environments (Claude Desktop, no shell):
- Higher context overhead (MCP tool schemas)
- Use only when CLI is unavailable
## Why CLI + Hooks Over MCP?
**Context efficiency matters**, even with large context windows:
1. **Compute cost scales with tokens** - Every token in your context consumes compute on every inference, regardless of whether it's used
2. **Latency increases with context** - Larger prompts take longer to process
3. **Energy consumption** - Each token has environmental impact; lean prompts are more sustainable
4. **Attention quality** - Models attend better to smaller, focused contexts
**The math:**
- MCP tool schemas can add 10-50k tokens to context (depending on number of tools)
- `bd prime` adds ~1-2k tokens of workflow context
- That's 10-50x less context overhead
**When context size doesn't matter:**
- MCP-only environments where CLI isn't available (Claude Desktop)
- Very short conversations where context overhead is negligible
**When to prefer CLI + hooks:**
- Any environment with shell access (Claude Code, Cursor, Windsurf, etc.)
- Long conversations or coding sessions
- Multi-editor workflows (CLI is universal)
## Why Not Claude Skills?
**Decision: Beads does NOT use or require Claude Skills (.claude/skills/)**
### Reasons
1. **Redundant with bd prime**
- `bd prime` already provides workflow context (~1-2k tokens)
- Skills would duplicate this information
- More systems = more complexity
2. **Simplicity is core to beads**
- Workflow fits in simple command set: ready → create → update → close → sync
- Already well-documented in ~1-2k tokens
- Complex workflow orchestration not needed
3. **Editor agnostic**
- Skills are Claude-specific
- Breaks beads' editor-agnostic philosophy
- Cursor, Windsurf, Zed, etc. wouldn't benefit
4. **Maintenance burden**
- Another system to document and test
- Another thing that can drift out of sync
- Another migration path when things change
### If Skills were needed...
They should be:
- Provided by the beads plugin (not bd core tool)
- Complementary (not replacing) bd prime
- Optional power-user workflows only
- Opt-in, never required
### Current approach is better
-`bd prime` - Universal context injection
- ✅ Hooks - Automatic context refresh
- ✅ Plugin - Optional Claude-specific enhancements
- ✅ MCP - Optional native tool access (legacy)
- ❌ Skills - Unnecessary complexity
Users who want custom Skills can create their own, but beads doesn't ship with or require them.
## Installation
```bash
# Install Claude Code hooks globally
bd setup claude
# Install for this project only
bd setup claude --project
# Use stealth mode (flush only, no git operations)
bd setup claude --stealth
# Check installation status
bd setup claude --check
# Remove hooks
bd setup claude --remove
```
**What it installs:**
- SessionStart hook: Runs `bd prime` when Claude Code starts a session
- PreCompact hook: Runs `bd prime` before context compaction to preserve workflow instructions
