🐕‍🦺 restory

The seatbelt for AI coding agents.

restory adds best-effort guardrails to your AI coding agent: it blocks dangerous commands before they run, records intercepted tool calls to a local timeline, and rolls back Git-visible workspace changes to the session baseline. Local-only. Claude Code · Gemini CLI (experimental).

Claude Code edits normally while restory records the session, blocks high-risk commands, and rolls the workspace back to the session baseline.

pip install restory && restory init   # then run your agent as usual
restory open                          # watch the live blast-radius timeline

Why this exists

AI coding agents (Claude Code, Cursor, Copilot) run as you — with your files, your keys, your shell. A single hallucination or a poisoned file in a repo can rm -rf your home dir or POST your .env to a pastebin. Allowlists don't catch it (CVE-2026-22708), and a container is too heavy for the inner loop.

restory sits between the agent and your machine: it inspects the effect of each command before it runs, records the tool calls it intercepts, and restores your Git-visible workspace changes with one keystroke.

What it does

• 🛑 Blocks dangerous effects — secret reads, network exfiltration, mass deletes, git-history nukes, writes outside the repo — before they execute.
• 📼 Records intercepted activity — a live, local timeline of the commands and file changes restory intercepts (Bash/Write/Edit tool calls).
• ↩️ Session rollback — restory undo --session rolls back the Git-visible working-tree changes captured during the session.
• 🔒 Local-only — no accounts, no cloud, nothing leaves your machine.

Commands

Example session report

Run restory export after a session to get a shareable report. Here's what a blocked session looks like:

Install

pip install restory
restory init                 # installs hooks for Claude Code (.claude/settings.json)
restory init --agent gemini  # experimental — Gemini CLI (.gemini/settings.json)
restory open                 # opens the live timeline at http://127.0.0.1:8765

Works on Windows, macOS, and Linux. Hook-based — no kernel driver, no container.

What restory does NOT do

Being honest, because security tools that overpromise get torn apart:

• It's not a sandbox and not a security boundary. A determined attacker with code execution can bypass static command inspection — shell wrappers (bash -c), scripts, indirect execution, and encoded commands all defeat it. Use an OS sandbox or container for a hard boundary; restory complements isolation, it doesn't replace it.
• Rollback has limits. undo reverses Git-visible working-tree changes that restory snapshotted. It does not reverse: data already exfiltrated, a completed git push or API call, changes outside the worktree, system/package changes, or files excluded by .gitignore (a gitignored .env may not be in the snapshot). Undo is a recovery tool for workspace state, not a safety net for confidentiality or remote side effects.
• It doesn't trace every file the agent touches. It classifies the intercepted tool calls (Bash/Write/Edit) — it doesn't do OS-level file-access tracing, and it doesn't currently intercept the agent's built-in Read tool. Concretely: an agent that reads a secret file via Read leaves no trace here, while the same read run as cat through Bash would be caught and classified.
• It doesn't replace your judgment. It surfaces what the agent tried and lets you reverse workspace changes. You're still the human in the loop.

FAQ

Why not just build this myself in a weekend? You could build a basic version — but "basic" is the trap. What's here is a shell-effect classifier that covers command-substitution, pipe-to-shell, find -delete, redirect writes, and the unquoted-~ expansion class; a shadow git repo that restores the Git-visible working tree to the session baseline; a live timeline; and an adapter layer for multiple agents. That's the difference between a weekend hack and something you'd actually trust on a real repo. pip install restory takes one second.

Isn't this just Claude Code's permission prompts? No. Native prompts are per-tool yes/no fatigue, they miss the ~/ expansion and shell-builtin bypass classes, they show no network-egress view, and they produce no shareable record. Restory is effect-aware, records the session, and gives you one-command workspace rollback. (CVE-2026-22708 is an example of why command allowlists are brittle — restory doesn't claim to remediate that specific Cursor vulnerability.)

Why not just run the agent in a container? Containers are great for isolation but too heavy for the everyday inner loop — especially on Windows. Restory is a hook, lightweight — no VM or container required.

Can't the classifier be bypassed? Yes — easily, and I don't hide it. Static inspection of shell can't win against bash -c, scripts, or encoded commands (my own selfcheck lists known bypasses). So the classifier is a best-effort pre-execution guard, not a boundary. For real containment, use an OS sandbox. What restory adds on top: a local audit trail, visibility, and workspace rollback for the cases it does catch.

Does it send my data anywhere? No. Everything is local — a SQLite store and a shadow git repo on your machine. No accounts, no cloud, no telemetry.

Why not just use Claude Code's sandbox? You should, when you can — restory isn't trying to replace OS-level isolation. A sandbox prevents classes of host/network effects at the OS boundary. restory adds a local timeline, auditable reports, best-effort pre-execution warnings, and session rollback around agent activity. They're complementary layers, not substitutes — use both.

How it works

restory init installs pre/post tool-use and session-start hooks for your agent (PreToolUse / PostToolUse on Claude Code, the equivalent BeforeTool / AfterTool on Gemini CLI). A thin adapter layer normalizes each agent's hook payload into one canonical shape and formats the decision each agent expects, so the classifier, store, and snapshot logic are shared unchanged across agents. Every tool call the agent makes is classified for blast radius; dangerous effects are blocked with a reason, everything is logged to a local SQLite store, and the working tree is snapshotted to a shadow git repo so undo can restore the Git-visible working-tree changes to the session baseline.

Roadmap

restory is actively developed. On the horizon: broader agent support, richer policy controls, and team features. Have a request? Open an issue — I'm prioritizing by what people actually ask for.
