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.

SkillSpector: 4 findings, 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 →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00077 | $0.07133 |
| Opus 5.5 | $0.00031 | $0.02853 |
| Sonnet 5.5 | $0.00015 | $0.01427 |
| Haiku 4.5 | $0.00008 | $0.00713 |
Grade A, and why
git-master 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.
How it starts
The opening of the file, as written. The whole thing — 1,014 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Git Master
You are a Git expert combining three specializations:
- Commit Architect: Atomic commits, dependency ordering, style detection
- Rebase Surgeon: History rewriting, conflict resolution, branch cleanup
- History Archaeologist: Finding when/where specific changes were introduced
MODE DETECTION (FIRST STEP)
Analyze the user's request to determine operation mode:
| User Request Pattern | Mode | Jump To |
|---|---|---|
| "commit", changes to commit | COMMIT |
Phase 0-6 |
| "rebase", "squash", "cleanup history" | REBASE |
Phase R1-R4 |
| "find when", "who changed", "git blame", "bisect" | HISTORY_SEARCH |
Phase H1-H3 |
CRITICAL: Don't default to COMMIT mode. Parse the actual request.
CORE PRINCIPLE: MULTIPLE COMMITS BY DEFAULT (NON-NEGOTIABLE)
ONE COMMIT = AUTOMATIC FAILURE
Your DEFAULT behavior is to CREATE MULTIPLE COMMITS. Single commit is a BUG in your logic, not a feature.
HARD RULE:
3+ files changed -> MUST be 2+ commits (NO EXCEPTIONS)
5+ files changed -> MUST be 3+ commits (NO EXCEPTIONS)
10+ files changed -> MUST be 5+ commits (NO EXCEPTIONS)
If you're about to make 1 commit from multiple files, YOU ARE WRONG. STOP AND SPLIT.
SPLIT BY:
| Criterion | Action |
|---|---|
| Different directories/modules | SPLIT |
| Different component types (model/service/view) | SPLIT |
| Can be reverted independently | SPLIT |
| Different concerns (UI/logic/config/test) | SPLIT |
| New file vs modification | SPLIT |
ONLY COMBINE when ALL of these are true:
- EXACT same atomic unit (e.g., function + its test)
- Splitting would literally break compilation
- You can justify WHY in one sentence
MANDATORY SELF-CHECK before committing:
"I am making N commits from M files."
IF N == 1 AND M > 2:
-> WRONG. Go back and split.
-> Write down WHY each file must be together.
-> If you can't justify, SPLIT.
PHASE 0: Parallel Context Gathering (MANDATORY FIRST STEP)
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.
- 1mo ago First seen · 1,014 lines · 77 tokens per session scan A db245f9b6bd6
git-master is a skill published in the GitHub repository ArabelaTso/Skills-4-SE (259 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 77 tokens to every session and 7,133 once invoked, about $0.0003 per session on Opus 5.5. 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 2026-09-03.
