iac-scanner CLAUDE.md

iac-scanner CLAUDE.md is an instructions file for coding agents from alphacrack/iac-scanner. It costs 1,699 tokens per session, scanned A, original, Apache-2.0.

Project instructions for iac-scanner, a Python command-line tool and MCP server that scans Terraform and AWS CDK infrastructure code. It uses an AI model to report issues and generate corrected code.

In plain words
What is it for?
Use it when working on iac-scanner, including installation, running its test suites, modifying the scanner, or checking its generated infrastructure fixes.
Why use it?
It gives coding agents the project's setup, testing, versioning, and security-checking rules in one place.

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 A, and why

iac-scanner CLAUDE.md scanned grade A with 0 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 3d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this project is

iac-scanner is a Python CLI (iac-scan) and MCP server (iac-scan-mcp) that scans Terraform (main.tf) and AWS CDK (index.ts/index.js) IaC, then uses an LLM to both generate findings (structured output) and produce fixed code. It is AI-augmented, not rule-only — it complements Checkov/tfsec/KICS rather than replacing them. Version is derived from git tags (signed vX.Y.Z) by setuptools-scm; pyproject.toml has dynamic = ["version"] and no hardcoded version. The package reads the version from _version.py (written at build time) or falls back to importlib.metadata.

Commands

# Setup
pip install -e ".[dev]"             # editable install + dev deps
pre-commit install                  # ruff + bandit + gitleaks + hygiene

# Test
pytest tests/ -m "not e2e"          # fast suite (mocked LLM, no keys)
pytest tests/ -m smoke              # CLI end-to-end smoke
pytest tests/ -m e2e                # opt-in: real provider APIs, needs keys
pytest tests/test_runner.py -v      # single file
pytest tests/test_runner.py::test_name  # single test
pytest tests/ --cov=iac_scanner     # coverage (CI threshold 80%, target 90%)

# Lint / type / security
ruff check src/ tests/              # lint
ruff format src/ tests/             # format
mypy src/iac_scanner                # CI hard-fails on any issue (strict mode)
bandit -r src/ -ll -c pyproject.toml
pip-audit

# Version + release (tag-driven, setuptools-scm)
make version                                # print version setuptools-scm would emit
make release-dry                            # preview a patch release
make release-patch | release-minor | release-major   # promote CHANGELOG + signed tag
# then: git push --follow-tags origin <branch>   # tag push → GitHub Release → PyPI publish

Make targets mirror most of the above (make test, make lint, make check, make build).

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.
