claude-smart-approval: Instructions file for Claude Code

CLAUDE.md

claude-smart-approval CLAUDE.md is an instructions file for Claude Code from froggeric/claude-smart-approval. It costs 2,160 tokens per session, scanned D, original, MIT.

Repository instructions for a Claude Code permission hook that checks shell commands before allowing, denying, or escalating them.

In plain words
What is it for?
Use them to run tests, lint shell scripts, evaluate prompt templates, debug command parsing, and inspect hook decisions.
Why use it?
They explain how the project parses compound commands and applies deny lists before asking Claude to make a further decision.

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 D, and why

claude-smart-approval CLAUDE.md scanned grade D with 3 findings 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 8d ago.

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.

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

Deny rules (and Stage 2's auto-learned allow patterns) are read from (in order): `~/.claude/settings.json`, `~/.claude/settings.local.json`, `<git-root>/.claude/settings.json`, `<git-root>/.claude/settings.local.json`. A

CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Project

Claude Code PermissionRequest hook — an AI permission tier for Bash commands. Fires only when Claude Code is about to prompt the user (requires Claude Code ≥ 2.0.45; top-level headless claude -p sessions don't fire the event). Stage 1 parses compound commands (pipes, chains, subshells) via shfmt AST and denies anything matching the user's deny lists. Everything else falls through to Stage 2, which evaluates via claude -p and emits an allow/deny decision object — or nothing, which escalates to the native prompt.

Commands

# Run all tests (requires bats, shfmt, jq)
bats test/

# Run a single test file
bats test/parsing.bats

# Lint shell scripts
shellcheck -x auto-approve.sh smart-approve.sh auto-learn.sh

# Evaluate a prompt template against the test suite
./eval-prompt.sh prompts/candidate-refined.txt --runs 3 --model haiku

# Debug a specific command's parsing
echo 'ls | grep foo' | ./auto-approve.sh parse

# Debug a full hook decision (deny gate + Stage 2 dispatch)
echo '{"tool_input":{"command":"ls | grep foo"}}' | ./auto-approve.sh --debug

# Exercise the working tree as a plugin (installed copy untouched), in a pty:
script -q /tmp/out claude --plugin-dir <repo-root> --settings <default-mode.json> "run exactly: <cmd>" </dev/null
# then read the two logs and pkill the hung TUI

Live-test gotchas: headless claude -p never fires PermissionRequest (useful only to confirm inactivity). Marker commands must have zero allow AND deny rules in all four settings layers, and commands Claude Code classifies as read-only (diff --version) never reach the hook.

CI

The workflow never auto-runs on push (it is registered, but push triggers are inert; cause unknown). Run it manually:

gh workflow run CI --ref master
gh run watch <run-id> --repo froggeric/claude-smart-approval --exit-status

bats and shellcheck are installed locally via brew: brew install bats-core shellcheck.

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.

claude-smart-approval CLAUDE.md is an instructions file published in the GitHub repository froggeric/claude-smart-approval (4 stars, last pushed 19d ago), licensed MIT. It adds 2,160 tokens to every session, about $0.0108 per session on Opus 5. A static security scan graded it D with 3 findings (reads agent configuration directories, recursive force delete, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
