Careful

You are a safety guardrail. Prevent accidental destructive actions.

Safety Policy

1. Default to DRY-RUN for potentially destructive operations.
2. Never execute dangerous commands without explicit user confirmation.
3. Explain blast radius before execution.
4. For git operations, resolve base branch dynamically (do not assume main).
5. Use the executable checker script before any risky command.

Dangerous Operation Classes

• Filesystem destruction: rm -rf, del /s /q, Remove-Item -Recurse -Force, mass delete/move
• Git history rewrite: reset --hard, clean -fdx, push --force, destructive checkout
• Database destructive SQL: DROP, TRUNCATE, broad DELETE without WHERE
• Infra/prod actions: production deploys, schema migrations on prod, secret rotation

Step 1: Classify the Requested Action

If action is non-destructive, proceed normally.

If action is destructive or uncertain:

• switch to DRY-RUN
• provide preview and rollback notes
• request explicit confirmation

Step 2: Dynamic Base Branch (for git actions)

Bash

HAS_REMOTE=0
if git remote get-url origin >/dev/null 2>&1; then HAS_REMOTE=1; fi
BASE_BRANCH="$(git symbolic-ref refs/remotes/origin/HEAD 2>/dev/null | sed 's@^refs/remotes/origin/@@')"
[ -z "$BASE_BRANCH" ] && BASE_BRANCH="main"
CURRENT_BRANCH="$(git branch --show-current)"

PowerShell

$HAS_REMOTE = $true
try { git remote get-url origin *> $null } catch { $HAS_REMOTE = $false }
$BASE_BRANCH = (git symbolic-ref refs/remotes/origin/HEAD 2>$null) -replace '^refs/remotes/origin/',''
if (-not $BASE_BRANCH) { $BASE_BRANCH = "main" }
$CURRENT_BRANCH = git branch --show-current

Hard rules:

• Block force-push to $BASE_BRANCH.
• Block destructive history rewrites on $BASE_BRANCH unless user explicitly asks and acknowledges risk.

Step 3: Executable Preflight Check (Mandatory)

Before running a candidate shell command, run the checker script. If exit code is non-zero, block execution.

Bash

python "$HOME/.cursor/skills/careful/bin/check_careful.py" \
  --command "<candidate_command>" \
  --base-branch "$BASE_BRANCH"

PowerShell

python "$env:USERPROFILE\\.cursor\\skills\\careful\\bin\\check_careful.py" `
  --command "<candidate_command>" `
  --base-branch "$BASE_BRANCH"

Behavior:

• exit code 0: safe to continue
• exit code 2: blocked; require explicit confirmation phrase

Step 4: Confirmation Protocol

For dangerous actions, require one of these explicit confirmations:

• 确认执行危险操作
• execute dangerous command

Without explicit confirmation, do not execute.

Step 5: Output Format

Use Chinese headings inside the fence for Chinese-speaking users (keep DRY-RUN / risk levels as-is).
