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 | $0.00040 | $0.02764 |
| Opus 5 | $0.00020 | $0.01382 |
| Sonnet 5 | $0.00008 | $0.00553 |
| Haiku 4.5 | $0.00004 | $0.00276 |
Grade A, and why
git-workflow-and-versioning 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.

Git Workflow and Versioning
Overview
When AI agents generate code at machine speed, version control becomes your only safety mechanism. Without it, a single bad generation can overwrite hours of work irreversibly. With it, every change is a save point you can inspect, revert, or compare.
The git contract: Every meaningful change gets its own commit with a clear message. Branches are short-lived (1-3 days max). History tells a story an engineer can follow. Commits are small enough to review in under 10 minutes. This isn't bureaucracy — it's the difference between confident experimentation and fearful coding.
Real-world impact: DORA research consistently shows trunk-based development correlates with elite engineering performance. Teams that merge small changes frequently have 60% fewer integration failures and recover from incidents 2x faster. Large, long-lived branches are where code goes to die — or worse, to create merge conflicts that take days to resolve.
When to Use
Always. Every code change flows through git.
Core Principles
Trunk-Based Development (Recommended)
Keep main always deployable. Work in short-lived feature branches that merge back within 1-3 days. Long-lived development branches are hidden costs — they diverge, create merge conflicts, and delay
integration. DORA research consistently shows trunk-based development correlates with high-performing engineering teams.
main ──●──●──●──●──●──●──●──●──●── (always deployable)
╲ ╱ ╲ ╱
●──●─╱ ●──╱ ← short-lived feature branches (1-3 days)
This is the recommended default. Teams using gitflow or long-lived branches can adapt the principles (atomic commits, small changes, descriptive messages) to their branching model — the commit discipline matters more than the specific branching strategy.
- Dev branches are costs. Every day a branch lives, it accumulates merge risk.
- Release branches are acceptable. When you need to stabilize a release while main moves forward.
- Feature flags > long branches. Prefer deploying incomplete work behind flags rather than keeping it on a branch for weeks.
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.

git-workflow-and-versioning is a skill published in the GitHub repository borhen68/SkillEngine (17 stars, last pushed 2mo ago), licensed MIT. It adds 40 tokens to every session and 2,764 once invoked, about $0.0002 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.
