Ralphmode

Ralphmode is a cross-platform permission profile for long-running ralph or omu workflows. It reduces approval friction, but it is not "allow everything everywhere." The core rule is simple: widen automation only inside a bounded project or disposable sandbox, and keep secrets plus destructive commands explicitly blocked.

When to use this skill

• You want ralph to iterate without repeated approval popups.
• You are setting up the same repo for Claude Code, Codex CLI, and Gemini CLI.
• You need a shared safety model: repo-only writes, no secrets reads, no destructive shell by default.
• You want a stronger separation between day-to-day automation and true YOLO mode.

Instructions

Step 1: Define the automation boundary first

Before changing any permission mode:

• Pick one project root and keep automation scoped there.
• List files and commands that must stay blocked: .env*, secrets/**, production credentials, rm -rf, sudo, unchecked curl | sh.
• Decide whether this is a normal repo or a disposable sandbox.

If the answer is "disposable sandbox," you may use the platform's highest-autonomy mode. If not, use the repo-scoped preset instead.

Step 2: Choose one preset per platform

Use only the section that matches the current tool:

• Claude Code: everyday preset first, bypassPermissions only for isolated sandboxes.
• Codex CLI: use the current official approval and sandbox model first; treat older permissions.allow and permissions.deny snippets as compatibility-only.
• Gemini CLI: trust only the project root; there is no true global YOLO mode.

Detailed templates live in references/permission-profiles.md.

Step 3: Apply the profile locally, not globally, unless the workspace is disposable

Prefer project-local configuration over user-global defaults.

• Claude Code: start with project .claude/settings.json.
• Codex CLI: start with project config and repo instructions or rules files.
• Gemini CLI: trust the current folder, not ~/ or broad parent directories.

If you must use a user-global default, pair it with a stricter denylist and a sandbox boundary.

Step 4: Run Ralph with an explicit verification loop

After permissions are configured:

1. Confirm the task and acceptance criteria.
2. Run ralph or the omu plan-execute-verify loop.
3. Verify outputs before claiming completion.
4. If the automation profile was temporary, revert it after the run.

Recommended execution contract:

boundary check -> permission profile -> ralph run -> verify -> cleanup or revert

Step 5: Keep "skip" and "safe" separate

Treat these as different modes:

• Repo automation: minimal prompts inside a bounded workspace.
• Sandbox YOLO: promptless execution in a disposable environment only.

Do not collapse them into one shared team default.

Step 6: Configure Mid-Execution Approval Checkpoints

Static permission profiles (Steps 2–3) reduce friction before a run starts, but they do not stop dangerous operations that arise during execution. Add dynamic checkpoints so that Tier 1 actions are blocked or flagged at the moment they are attempted.

Dangerous operation tiers

Tier	Action	Platform response
Tier 1 (always block)	rm -rf, git reset --hard, git push --force, DROP TABLE, sudo, .env*/secrets/** access, production environment changes	Block immediately, require explicit user approval
Tier 2 (warn)	npm publish, docker push, git push (non-force), DB migrations	Output warning, continue only with confirmation
Tier 3 (allow)	File reads/edits, tests, local builds, lint	Allow automatically

Platform checkpoint mechanisms

Platform	Hook	Blocking	Recommended pattern
Claude Code	PreToolUse (Bash)	Yes — exit 2	Shell script pattern-matches command; blocks Tier 1
Gemini CLI	BeforeTool	Yes — non-zero exit	Shell script blocks tool; stderr fed to next turn
Codex CLI	notify (post-turn)	No	approval_policy="unless-allow-listed" + prompt contract
OpenCode	None	No	Prompt contract in opencode.json instructions

Principle: Combine static profiles (Steps 2–3) with dynamic checkpoints (this step).

• Platforms with pre-tool hooks (Claude Code, Gemini): use the hook script.
• Platforms without (Codex, OpenCode): rely on approval_policy and explicit prompt contracts that instruct the agent to output CHECKPOINT_NEEDED: <reason> and wait before proceeding with Tier 1 actions.

See references/permission-profiles.md for full hook script templates per platform.

Examples

Example 1: Claude Code sandbox run

Use the Claude sandbox preset from references/permission-profiles.md, then run Ralph only inside that isolated repo:

/ralph "fix all failing tests" --max-iterations=10

Example 2: Codex CLI repo-scoped Ralph run

Apply the Codex repo preset from references/permission-profiles.md, then run the task. The current official model uses config file settings, not CLI flag overrides:

approval_policy = "never"
sandbox_mode = "workspace-write"

Place this in ~/.codex/config.toml (or a project-local override) and restart Codex before running Ralph.

Example 3: Gemini CLI trust-only setup

Trust the current project folder, keep explicit file selection, then run the Ralph workflow for that repo only.

Best practices

• Default to the least-permissive preset that still lets Ralph finish end-to-end.
• Keep secret denylists and destructive command denylists even when approvals are reduced.
• Use full bypass only in disposable environments with a clear project boundary.
• Record which preset was applied so teammates can reproduce or revert it.
• Re-check platform docs when upgrading CLI versions because permission models change faster than skill content.
