freeze

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". (gstack)

/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).

mkdir -p ~/.gstack/analytics
echo '{"skill":"freeze","ts":"'$(date -u +%Y-%m-%dT%H:%M:%SZ)'","repo":"'$(basename "$(git rev-parse --show-toplevel 2>/dev/null)" 2>/dev/null || echo "unknown")'"}'  >> ~/.gstack/analytics/skill-usage.jsonl 2>/dev/null || true

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:

Resolve it to an absolute path:

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

Ensure trailing slash and save to the freeze state file:

FREEZE_DIR="${FREEZE_DIR%/}/"
eval "$(~/.claude/skills/gstack/bin/gstack-paths)"
STATE_DIR="$GSTACK_STATE_ROOT"
mkdir -p "$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

概要と使いどころ

ab-test-setup

無料

When the user wants to plan, design, or implement an A/B test or experiment. Also use when the user mentions "A/B test," "split test," "experiment," "test this change," "variant copy," "multivariate test," "hypothesis," "should I test this," "which version is better," "test two versions," "statistical significance," or "how long should I run this test." Use this whenever someone is comparing two approaches and wants to measure which performs better. For tracking implementation, see analytics-tracking. For page-level conversion optimization, see page-cro.
