Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# claude-io-guard

io-guard is a Claude Code plugin that checks what an agent sends to the file and shell tools, fixes what it safely
can, and returns a structured error for the rest. One codebase runs on Windows and macOS. This repository is also the
plugin's marketplace: github.com/Riztazz/claude-io-guard.

## Layout

The tasks build most of this. Today the marketplace, the plugin's manifest, hooks, launcher, skills, the
`ioguard` package's runtime core (`lib/` and the pipeline in `checks/`, with twenty-two checks: the session
probe, `write.location`, `write.locks`, `shell.writes`, `transport.body`, `shell.lint`, `win.paths`, `conform.write`,
`conform.edit`, `verify.write`, `verify.command`, `shell.touched`, `read.profile`, `diagnose.failure`,
`diagnose.refused`, `shell.results`, `server.heartbeat`, `run.rules`, `commit.policy`, `restore.ask`,
`trust.ask` and `journal.write`), the hook entry point and bridge in `hooks/`, the io MCP server in `mcp/` with
`io.read`, `io.edit`, `io.splice`, `io.append`, `io.run`, `io.status`, `io.read_log`, `io.format`, `io.snapshot`,
`io.restore`, `io.compare`, `io.stage`, `io.config`, `io.dashboard`, `io.trust` and the hook tools, the corpus,
…

How to install

The exact contents, by fingerprint
mdr add riztazz/claude-io-guard/CLAUDE.md@sha256:2474d502c55c9a95

The line at the top of this page pins the label git:20260929.7d9f2b2, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
