-- **Language**: Go 1.21+
-- **Storage**: SQLite (internal/storage/sqlite/)
-- **CLI Framework**: Cobra
-- **Testing**: Go standard testing + table-driven tests
-- **CI/CD**: GitHub Actions
-- **MCP Server**: Python (integrations/beads-mcp/)

-## Coding Guidelines
-
-### Testing
-- Always write tests for new features
-- Use `BEADS_DB=/tmp/test.db` to avoid polluting production database
-- Run `go test -short ./...` before committing
-- Never create test issues in production DB (use temporary DB)
-
-### Code Style
-- Run `golangci-lint run ./...` before committing
-- Follow existing patterns in `cmd/bd/` for new commands
-- Add `--json` flag to all commands for programmatic use
-- Update docs when changing behavior
-
-### Git Workflow
-- Always commit `.beads/issues.jsonl` with code changes
-- Run `bd sync` at end of work sessions
-- Install git hooks: `bd hooks install` (ensures DB ↔ JSONL consistency)

 ### MCP Server (Recommended)
-Use the beads MCP server for native function calls instead of shell commands:
+
+For MCP-compatible clients (Claude Desktop, etc.), install the beads MCP server:
 - Install: `pip install beads-mcp`
 - Functions: `mcp__beads__ready()`, `mcp__beads__create()`, etc.
-- See `integrations/beads-mcp/README.md`
