Why choose Dejavu: Stop showing coding agents the same command output twice — deduplicates terminal output to save tokens and improve agent efficiency

Optimal workflow match: Ideal for teams seeking automated and streamlined AI workflows.

✅ Pros / Key Advantages

• PATH shim architecture — intercepts commands by placing a shim directory at the front of PATH; always runs the real command, only changes what the agent sees on repeated runs
• Cross-run deduplication — remembers previous command output and returns only a compact delta (or 'unchanged' notice) when output is identical or nearly identical, suppressing redundant tokens
• Zero-prompt integration — works without instructing the agent to behave differently; no MCP protocol or prompt engineering required, the shim is transparent to the agent
• Agent-gated activation — reduces output only when an agent context is detected (CLAUDECODE, CODEX_SANDBOX, CURSOR_AGENT, AI_AGENT/COPILOT_AGENT markers); normal terminal sessions get raw output
• Multi-agent support — works with Claude Code, Codex CLI, Cursor agent, opencode, Aider, Gemini CLI, and VS Code Copilot agent mode
