freeze

name	freeze
argument-hint	<directory>
preamble-tier	1
version	0.1.0
description	Restrict file edits to a specific directory for the session. Blocks Edit and Write outside the allowed path. Use when debugging to prevent accidentally "fixing" unrelated code, or when you want to scope changes to one module. Use when asked to "freeze", "restrict edits", "only edit this folder", or "lock down edits".

Preamble (run first)

# === RKstack Preamble (freeze) ===

# Read detection cache (written by session-start via rkstack detect)
if [ -f .rkstack/settings.json ]; then
  cat .rkstack/settings.json
else
  echo "WARNING: .rkstack/settings.json not found — detection cache missing"
fi

# Session-volatile checks (can change mid-session)
_BRANCH=$(git branch --show-current 2>/dev/null || echo "unknown")
_HAS_CLAUDE_MD=$([ -f CLAUDE.md ] && echo "yes" || echo "no")
echo "BRANCH: $_BRANCH"
echo "CLAUDE_MD: $_HAS_CLAUDE_MD"

Use the detection cache and preamble output to adapt your behavior:

• TypeScript/JavaScript — see detection.flowType (web or default). If web: check React/Vue/Svelte patterns, responsive design, component architecture. If default: CLI tools, MCP servers, backend scripts.
• Python — backend/ML/scripts. Check PEP8 conventions, pytest for testing.
• Go — backend/infra. Check error handling patterns, go test.
• Rust — systems. Check ownership patterns, cargo test.
• Java/C# — enterprise. Check build tool (Maven/Gradle/.NET), framework conventions.
• Ruby — web/scripting. Check Gemfile, Rails conventions if present.
• Terraform/HCL — infrastructure as code. Plan before apply, extra caution with state.
• Ansible — configuration management. Check inventory, role conventions, vault usage.
• Docker/Compose — containerized. Check service dependencies, .env patterns.
• justfile — task runner present. Use just commands instead of raw shell.
• mise — tool version manager. Versions are pinned — don't suggest global installs.
• CLAUDE.md exists — read it for project-specific commands and conventions.
• Read detection.stack for what's in the project and detection.stats for scale (files, code, complexity).
• Read detection.repoMode for solo vs collaborative.
• Read detection.services for Supabase and other service integrations.

Completion Status

When completing a skill workflow, report status using one of:

• DONE — All steps completed successfully. Evidence provided for each claim.
• DONE_WITH_CONCERNS — Completed, but with issues the user should know about. List each concern.
• BLOCKED — Cannot proceed. State what is blocking and what was tried.
• NEEDS_CONTEXT — Missing information required to continue. State exactly what you need.

Escalation

It is always OK to stop and say "this is too hard for me" or "I'm not confident in this result."

Bad work is worse than no work. You will not be penalized for escalating.

• If you have attempted a task 3 times without success, STOP and escalate.
• If you are uncertain about a security-sensitive change, STOP and escalate.
• If the scope of work exceeds what you can verify, STOP and escalate.

Escalation format:

STATUS: BLOCKED | NEEDS_CONTEXT
REASON: [1-2 sentences]
ATTEMPTED: [what you tried]
RECOMMENDATION: [what the user should do next]

/freeze — Restrict Edits to a Directory

Lock file edits to a specific directory. Any Edit or Write operation targeting a file outside the allowed path will be blocked (not just warned).

Setup

Ask the user which directory to restrict edits to. Use AskUserQuestion:

• Question: "Which directory should I restrict edits to? Files outside this path will be blocked from editing."
• Text input (not multiple choice) — the user types a path.

Once the user provides a directory path:

1. Resolve it to an absolute path:

FREEZE_DIR=$(cd "<user-provided-path>" 2>/dev/null && pwd)
echo "$FREEZE_DIR"

2. Ensure trailing slash and save to the freeze state file:

FREEZE_DIR="${FREEZE_DIR%/}/"
STATE_DIR="${CLAUDE_PLUGIN_DATA:-$HOME/.rkstack}"
mkdir -p "$STATE_DIR"
echo "$FREEZE_DIR" > "$STATE_DIR/freeze-dir.txt"
echo "Freeze boundary set: $FREEZE_DIR"

Tell the user: "Edits are now restricted to <path>/. Any Edit or Write outside this directory will be blocked. To change the boundary, run /freeze again. To remove it, run /unfreeze or end the session."

How it works

The hook reads file_path from the Edit/Write tool input JSON, then checks whether the path starts with the freeze directory. If not, it returns permissionDecision: "deny" to block the operation.

The freeze boundary persists for the session via the state file. The hook script reads it on every Edit/Write invocation.

Notes

• The trailing / on the freeze directory prevents /src from matching /src-old
• Freeze applies to Edit and Write tools only — Read, Bash, Glob, Grep are unaffected
• This prevents accidental edits, not a security boundary — Bash commands like sed can still modify files outside the boundary
• To deactivate, run /unfreeze or end the conversation
