README excerpt
Read full README on GitHub →Entroly — Select AI context with auditable recovery.
Receipt-backed selection records: what was kept, what was omitted, and the handle that recovers the exact original bytes. Compression you can undo, on your own repository, in one command — without replacing your model or agent architecture.
pip install -U entroly · entroly verify-claims · entroly simulate
Entroly is an open-source, local-first AI token-efficiency and Context Assurance layer: budgeted evidence selection, recoverable context compression, content-addressed evidence recovery, and auditable receipts. Works through VS Code, Claude Code, Cursor, Codex, OpenClaw, GitHub Copilot, Aider, and OpenAI/Anthropic-compatible apps.

What is Entroly? (in plain English)
Entroly is a local-first context control plane for AI coding tools. It selects evidence within a token budget, preserves recoverable omissions, and records selection decisions in receipts. Three properties to evaluate on your task:
| 💰 Avoidable input cost | Smaller requests can reduce input cost when they reach a provider through an Entroly-controlled route. The result depends on the workload and provider cache — see the real numbers below. |
| 🔍 Recoverable originals | Receipt-backed recovery retains source material locally. Exact recovery requires the referenced store and source bytes to remain available; it does not guarantee answer quality. |
| 🧾 You can check its work | Every decision comes with a receipt: what was kept, what was left out, and why. |
Do I have to change my code? No. On hosts with a verified prompt hook,
Entroly runs before the model plans. MCP-only integrations remain callable
tools that an agent may skip; API traffic is intercepted only when it is routed
through the Entroly proxy. Check entroly activation status --json instead of
assuming an installed integration is active.
Do I need to pay for anything to try it? No. The two commands in the Install section below run on your own machine, with no API key, and show you real numbers on your own project before you connect anything paid. (Missing native-engine support is reported without downloading packages — see the note under Install.)
Switching coding agents mid-task? entroly-work resume reconstructs
unfinished work from durable repository evidence, even if the previous agent
left no handoff. The receiving agent must review the inferred state and
acknowledge it before claiming work through Entroly. Start with
entroly-work --project . --json resume --to-agent codex;
the agent continuity guide shows the complete flow
and how to measure whether it actually saves rediscovery work on your tasks.
