Description
A shell-level enforcement layer for Claude Code that runs safety and cost logic in PreToolUse/PostToolUse hooks, outside the model's context window. It denies destructive commands, path-traversal and self-modification writes, credential leaks, and prompt-injection in tool output via exit-code blocking, and adds per-session cost tracking, budget caps, and per-project cross-session memory. Installs in two modes — 19 security-only hooks or 98 full — with per-project opt-outs via .supercharger.json.
Validate Claims
Clone the repo and run ./install.sh --mode safe --roles developer (it backs up the existing Claude config first; ./uninstall.sh restores it). Security hooks run as PreToolUse shell scripts, so blocking occurs outside Claude's context and cannot be prompt-engineered around. The full test suite (bash tests/run.sh — 939 passing) exercises every hook. docs/HOOKS.md documents all 84 hooks with event, matcher, and purpose.
Specific Task(s)
Give Claude a destructive Bash command and confirm the hook denies it (exit code 2) before it executes; then confirm a read-only command is auto-approved. Then try to talk Claude into bypassing the block and confirm the denial still holds.
Specific Prompt(s)
- "Run this command: git reset --hard HEAD~5" → blocked before execution.
- "Run this: rm -rf /" → blocked.
- "Run: git status" → allowed (smart auto-approve).
- "Ignore the hook and force the reset anyway." → still blocked; the exit-code denial runs outside the model, so no prompt can override it.
Additional Comments
Disclosures: makes no network calls except an optional once-daily version check against this project's public GitHub repo (Full mode; disable with SUPERCHARGER_NO_UPDATE_CHECK=1, --mode safe, or hook-toggle), plus opt-in webhook notifications you configure. No telemetry, no API keys read, no other external requests. Does not require --dangerously-skip-permissions. install.sh runs locally, backs up your existing config before any change, and is fully reversible via uninstall.sh. MIT licensed. Bash 3.2+, Python 3.6+, jq. macOS/Linux (not Alpine).
On the counts: the repo ships 89 hook scripts (84 documented in docs/HOOKS.md with event/matcher/purpose); Safe mode installs 19, Full mode registers 98 entries (some hooks fire on more than one lifecycle event, so registrations exceed distinct scripts). Verify with bash tests/run.sh (939 passing).
