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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.02160 | $0.02160 |
| Opus 5 | $0.01080 | $0.01080 |
| Sonnet 5 | $0.00432 | $0.00432 |
| Haiku 4.5 | $0.00216 | $0.00216 |
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.
Reads agent configuration directoriesmediumAgent snooping
.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 Recursive force deletehighDestructive command
rm -rf with a variable or a broad path is one typo away from removing the wrong tree.
Stage 1 log (`auto-approve.log`) is deny-only: JSONL with fields `ts`, `cmd`, `decision`, `matched_prefix`, `type` (simple/compound). Allow decisions are Stage 2's and live in `smart-approval.log` (`ts`, `cmd`, `decision Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.

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.
