devtu-github is a skill for Claude Code, Codex from mims-harvard/ToolUniverse. It costs 51 tokens per session (1,922 once invoked), scanned A, original, Apache-2.0.

A GitHub workflow guide for preparing ToolUniverse code before commits and pushes. It includes cleaning temporary files, enabling automated checks, and running tests.

In plain words
What is it for?
Use it to prepare a branch, check what Git will include, run pre-commit checks and tests, and fix issues before pushing to GitHub.
Why use it?
It reduces the chance of sending credentials, session files, ad-hoc tests, or unverified code to a shared repository.

About the project

ToolUniverse is a collection of tools, interfaces, and supporting components for building AI systems that perform scientific work. It is for developers creating AI scientist agents that use APIs, databases, machine-learning tools, and domain-specific utilities. The catalogue includes skills, commands, an MCP server, an agent, and a hook for working with the ecosystem.

SkillSpector: 1 finding, up to high

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Tool parameters are crafted to achieve unintended or unsafe behavior. Parameter abuse can bypass intended safety checks (e.g. shell=True, --force, dangerous glob patterns).
    Fix: Validate all tool parameters against an allowlist. Reject dangerous parameter values (shell=True, --force, -rf /) and use safe defaults.

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 1mo 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):

Files

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
