devtu-github

A GitHub workflow for preparing ToolUniverse code before it is pushed to a shared code repository.

In plain words
What is it for?
Use it to clean the working tree, enable pre-commit checks, run tests and linting, inspect staged files, and prepare for CI fixes or a push.
Why use it?
It helps keep temporary files and credentials out of commits and catches code or test problems before they reach GitHub.

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

devtu-github 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.

DevTU GitHub Workflow

Safely push ToolUniverse code to GitHub by enforcing pre-push cleanup, pre-commit hooks, and test validation.

Instructions

When the user wants to push code, fix CI, or prepare a commit, follow this workflow:

Phase 1: Pre-Push Cleanup

  1. Move temp files out of root - session docs and ad-hoc test scripts must NOT be pushed:
# Move session markdown files to temp_docs_and_tests/
for f in $(ls *.md 2>/dev/null | grep -v README.md | grep -v CHANGELOG.md | grep -v LICENSE.md); do
  mv "$f" temp_docs_and_tests/
done

# Move root-level test scripts to temp_docs_and_tests/
for f in $(ls test_*.py 2>/dev/null); do
  mv "$f" temp_docs_and_tests/
done
  1. Verify nothing unwanted is staged:
git status --short

Red flags - these should NEVER be staged:

  • *_SUMMARY.md, *_REPORT.md, SESSION_*.md in root
  • test_*.py in root (these are ad-hoc scripts, not real tests)
  • .env or credential files
  • temp_docs_and_tests/ contents

Phase 2: Activate Pre-Commit Hooks

  1. Ensure pre-commit is installed and active:
pre-commit install

This enables automatic checks on every git commit:

  • ruff check --fix - Python linting with auto-fix
  • ruff format - Code formatting
  • YAML/TOML validation
  • Trailing whitespace removal
  • End of file fixes
  1. Verify hooks are active:
ls -la .git/hooks/pre-commit

Phase 3: Run Tests

  1. Run the full test suite locally:
python -m pytest tests/ -x --tb=short -q
  1. If tests fail, diagnose using the error patterns below and fix before proceeding.

Phase 4: Commit and Push

  1. Stage only specific files (never use git add . or git add -A):
git add src/tooluniverse/specific_file.py tests/specific_test.py
  1. Commit (pre-commit hooks run automatically):
git commit -m "Clear, descriptive message"
  1. Rebase onto latest main BEFORE pushing (CRITICAL — prevents PR conflicts):

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.

devtu-github is a skill published in the GitHub repository Zaoqu-Liu/ScienceClaw (59 stars, last pushed 5mo ago), licensed MIT. It adds 51 tokens to every session and 1,922 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
