fix-python

fix-python is a skill for Claude Code from quay/ai-helpers. It costs 31 tokens per session (489 once invoked), scanned A, original, MIT.

A Python dependency update procedure for fixing a known CVE, a publicly tracked security vulnerability. It changes the package version, rebuilds the dependency lock-style file with hashes, and checks the result with pip-audit.

In plain words
What is it for?
Use it when you know the affected package, fixed version, CVE identifier, and repository directory. It updates requirements files and requirements-build.txt, with an optional workaround for a setuptools build issue.
Why use it?
It removes the repetitive steps involved in applying a Python dependency security fix. The audit check helps identify whether the specified vulnerability still appears after the update.

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

fix-python 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 2d 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 it actually says

Fix Python CVE

Inputs

Input Required
PACKAGE yes
FIXED_VERSION yes
CVE_ID yes
REPO_DIR yes (cwd)
CVE_PYBUILD_SETUPTOOLS_WORKAROUND optional, default false

Steps

1. Find requirements file

REQ_FILE=""
for f in requirements.txt requirements-dev.txt; do
  if grep -qi "^${PACKAGE}" "$f" 2>/dev/null; then
    REQ_FILE="$f"
    break
  fi
done

2. Bump version pin

ESCAPED_PACKAGE=$(printf '%s\n' "$PACKAGE" | sed 's/[.[\*^$]/\\&/g')
sed -i "s/^${ESCAPED_PACKAGE}[=>~!][=<>~!]*.*$/${PACKAGE}>=${FIXED_VERSION}/" "$REQ_FILE"

3. Regenerate requirements-build.txt

pybuild-deps compile --generate-hashes --output-file=requirements-build.txt requirements.txt

if [ "${CVE_PYBUILD_SETUPTOOLS_WORKAROUND:-false}" = "true" ]; then
  sed -i '/^setuptools==82\b/d' requirements-build.txt
fi

4. Verify

grep "${PACKAGE}" requirements-build.txt
pip-audit -r requirements.txt 2>/dev/null | grep -i "${CVE_ID}" && \
  echo "WARNING: CVE still detected" || echo "CVE resolved in scan"

Output

Modified requirements*.txt and requirements-build.txt in REPO_DIR.

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.
