Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00051 | $0.01922 |
| Opus 5 | $0.00026 | $0.00961 |
| Sonnet 5 | $0.00010 | $0.00384 |
| Haiku 4.5 | $0.00005 | $0.00192 |
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.
How it starts
The opening of the file, as written. The whole thing — 240 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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
- 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
- Verify nothing unwanted is staged:
git status --short
Red flags - these should NEVER be staged:
*_SUMMARY.md,*_REPORT.md,SESSION_*.mdin roottest_*.pyin root (these are ad-hoc scripts, not real tests).envor credential filestemp_docs_and_tests/contents
Phase 2: Activate Pre-Commit Hooks
- 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-fixruff format- Code formatting- YAML/TOML validation
- Trailing whitespace removal
- End of file fixes
- Verify hooks are active:
ls -la .git/hooks/pre-commit
Phase 3: Run Tests
- Run the full test suite locally:
python -m pytest tests/ -x --tb=short -q
- If tests fail, diagnose using the error patterns below and fix before proceeding.
Phase 4: Commit and Push
- Stage only specific files (never use
git add .orgit add -A):
git add src/tooluniverse/specific_file.py tests/specific_test.py
- Commit (pre-commit hooks run automatically):
git commit -m "Clear, descriptive message"
- 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.
