careful

careful is a skill for Claude Code from yonatangross/orchestkit. It costs 84 tokens per session (1,342 once invoked), scanned C, original, MIT.

A safety guard for shell commands that blocks several destructive actions after it is enabled, including broad file deletion, force-pushing Git branches, deleting database data, and destroying cloud resources.

In plain words
What is it for?
Use it during coding sessions where commands may affect repositories, databases, Kubernetes resources, Terraform-managed infrastructure, or remote machines.
Why use it?
It reduces the chance that an agent or developer will erase files, rewrite shared Git history, delete database contents, or remove infrastructure by mistake.

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

careful 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 15d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/careful-guard.mjs), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Recursive force deletehighDestructive command

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

How it starts

The opening of the file, as written. The whole thing — 87 lines — stays where its author put it; the contents beside it link to each section on GitHub.

careful, block destructive commands for this session

Invoking this skill registers a PreToolUse hook on Bash (the hooks: block above). Claude Code keeps a skill's hooks registered for the rest of the session, on every later turn, so careful stays on until the session ends. There is no off switch: start a new session to work without it.

What it blocks

Rule Blocks Still allowed
rm-rf rm with recursive and force flags (-rf, -fr, -r -f, --recursive --force), xargs rm -rf, and any target the shell expands: $TMPDIR/x, $TMP, $TEMP, $X, $( ), globs, braces, ~ the same command when every target is a LITERAL absolute path that lands, after following existing symlinks, strictly inside /tmp, /private/tmp or the configured TMPDIR (trusted only when it is two or more levels deep); write /tmp/build, not $TMPDIR/build, because a command can reassign TMPDIR first (TMPDIR=/ ; rm -rf $TMPDIR/usr); rm -r; rm -f file
git-push-force git push --force, -f (also inside -uf), --force-with-lease[=...], a +branch refspec, to any branch git push, git push -u origin <branch>
git-push-delete git push origin --delete <b>, -d <b>, :<b> git push origin <b>:<b>
git-reset-hard git reset --hard git reset --soft, git reset HEAD <file>
sql-drop DROP TABLE, DROP DATABASE, DROP SCHEMA anywhere in the command, heredocs included a SELECT that mentions drop
sql-truncate TRUNCATE TABLE, or a TRUNCATE <name> statement sent to a SQL client truncate -s 0 file.log
kubectl-delete kubectl ... delete kubectl get, kubectl logs
terraform-destroy terraform destroy, terraform apply -destroy, the same with tofu terraform plan, terraform apply

Matching is on shell words, not substrings: a commit message or grep pattern that quotes git push --force is text, not a push. Compound commands are split on ;, &&, | and newlines, and the bodies of bash -c, eval, $( ) and the remote command of ssh host '...' are checked as well.

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.

careful is a skill published in the GitHub repository yonatangross/orchestkit (295 stars, last pushed today), licensed MIT. It adds 84 tokens to every session and 1,342 once invoked, about $0.0003 per session on Opus 5.5. 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 2026-10-02.
