octo-guard

octo-guard is a command for Claude Code, Cursor from nyldn/claude-octopus. It costs 11 tokens per session (502 once invoked), scanned C, original, MIT.

A command that turns on two safety controls at once: warnings for destructive shell commands and a restriction that limits file edits to a chosen directory.

In plain words
What is it for?
Use it for focused work in sensitive repositories, especially when you want both command warnings and an edit boundary.
Why use it?
It helps prevent damaging commands and accidental changes outside the part of the codebase you are working on.

Command for Claude CodeCursor

Written for Claude Code and Cursor: disable-model-invocation in frontmatter, but also a Cursor plugin manifest. Also seen: positional $N argument.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is /octo:guard ./packages/core.

About the project

Claude Octopus is an orchestration project that sends research, design, and coding tasks to Claude Code and other AI model providers so their results can be compared. Developers use it for multi-model work, disagreement detection, reviews, persistent context, and an optional workflow that moves from discovery through delivery. The catalogue entries are its commands, skills, agents, instructions, hooks, plugins, and settings.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade C, and why

octo-guard scanned grade C with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

What it actually says

Guard Mode - Full Safety Activation

Instructions

When the user invokes /octo:guard <directory>, activate both careful mode and freeze mode in a single command.

Activation

  1. Activate careful mode (destructive command warnings):
_OCTO_SESSION_ID="${CLAUDE_CODE_SESSION_ID:-${CLAUDE_SESSION_ID:-$$}}"
echo "active" > "/tmp/octopus-careful-${_OCTO_SESSION_ID}.txt"
  1. Activate freeze mode (edit boundary enforcement):
freeze_dir="$(cd "$1" 2>/dev/null && pwd)" || freeze_dir="$1"
_OCTO_SESSION_ID="${CLAUDE_CODE_SESSION_ID:-${CLAUDE_SESSION_ID:-$$}}"
echo "${freeze_dir}" > "/tmp/octopus-freeze-${_OCTO_SESSION_ID}.txt"

What It Does

Guard mode combines both safety primitives:

  • Careful mode: Warns before destructive Bash commands (rm -rf, DROP TABLE, git push --force, etc.)
  • Freeze mode: Blocks Edit/Write operations outside the specified directory

This is the recommended safety configuration for focused work in sensitive codebases.

Usage

/octo:guard src/auth
/octo:guard ./packages/core
/octo:guard /absolute/path/to/module

After activation, confirm to the user:

🛡️ Guard mode activated:
   ⚠️ Careful: Destructive commands require confirmation
   🔒 Freeze: Edits restricted to <resolved-path>
   Use /octo:unfreeze to remove edit restriction.

Argument Required

If invoked without a directory argument, activate only careful mode and ask about freeze:

⚠️ Careful mode activated (destructive command warnings).
Which directory should I restrict edits to? Example: /octo:guard src/auth

When to Use

  • Starting work in a production-adjacent codebase
  • Debugging with maximum safety
  • When you want both protections without two separate commands

  • /octo:careful — Activate only destructive command warnings
  • /octo:freeze — Activate only edit boundary enforcement
  • /octo:unfreeze — Remove freeze restriction
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

octo-guard is a command published in the GitHub repository nyldn/claude-octopus (4,062 stars, last pushed today), licensed MIT. It adds 11 tokens to every session and 502 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it C with 1 finding (recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
