Guides
- Running several Claude Code agents in one repoThe setup, and what breaks first.
- Claude Code, Codex CLI and Cursor togetherThree vendors, one working tree, one rule.
- Claude Code and Cursor on one repoThe two-tool setup, snippet by snippet.
- Stopping agents overwriting each otherThree fixes ranked, and the one that catches uncommitted loss.
- Why agents cause merge conflictsA coordination failure surfacing late, and the two ways out.
- Advisory locks vs enforced locksWhy refusing a claim beats blocking a write.
- Best tools for running multiple agentsThe honest survey: worktrees, sequential, coordination, orchestrators.
Comparisons
- MCP coordination servers, comparedTwenty-five of them, checked against the API rather than a directory.
- Befall vs MCP Agent MailThe other coordination server, compared without flattering ourselves.
- Befall vs git worktreesIsolation and coordination solve different halves.
- Isolation vs coordinationThe whole category mapped along one axis.
- Subagents vs independent instancesOne orchestrator's context, or peers that outlive the session.
- Befall vs Claude Code agent teamsIn-session teammates against cross-tool peers.
