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 | $0.00089 | $0.03359 |
| Opus 5 | $0.00044 | $0.01680 |
| Sonnet 5 | $0.00018 | $0.00672 |
| Haiku 4.5 | $0.00009 | $0.00336 |
Grade A, and why
git 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 — 201 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Git Operations
Advanced git workflows: rebase surgery, conflict resolution, and coexistence in shared multi-agent repos.
PR Branch Upkeep
The most-run workflow: keeping your own PR branch current against a moving main.
The loop: fetch → backup ref → rebase → re-run gates on the rebased SHA (pre-rebase receipts are void) → fetch again as the last pre-push step. Main moves mid-session; expect to loop. Three rebases in one turn is normal, each with a fresh backup. The exit condition is machine-checkable, not vibes:
git merge-base --is-ancestor origin/main HEAD && echo "based on current main"
Review etiquette: while a reviewer (bot, human, or agent) is actively reading, hold pushes. Batch fixes, then one rebase+push when the review lands. Freshness loops run at push boundaries.
Pushing rewritten history
Pin the lease. An unpinned --force-with-lease is satisfied by your own stale fetch:
git ls-remote origin refs/heads/<branch> # confirm the expected SHA immediately before pushing
git push --force-with-lease=refs/heads/<branch>:<expected-sha> origin HEAD:<branch>
On a "stale info" rejection, diagnose with ls-remote before any retry. Observed causes: auto-delete-on-merge removed the branch, a typo'd lease SHA, or the remote legitimately moved. Bare --force is not an escalation path.
After the base squash-merges
When a parent PR squash-merges, its commits vanish from main's ancestry. A plain rebase replays them as ghosts. Detect the merge type first: squash, rebase-merge, and merge-commit each leave different ancestry.
| Situation | Move |
|---|---|
| Parent PR squash-merged | git rebase --onto <new-base> <old-base-sha>: only your own commits replay |
| Replay keeps conflicting / branch polluted | Rebuild as main + delta: one git diff --binary patch from the backup, applied onto fresh main; prove with range-diff |
| Pushing fixes to an old branch | Verify PR open-state first. A squash-merged PR's branch is dead |
| Stacked chain | Cascade bottom-up with --onto, per-level backup, push bottom-first (validators diff against origin/<base>) |
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 is a skill published in the GitHub repository hyperb1iss/hyperskills (31 stars, last pushed 6d ago), licensed MIT. It adds 89 tokens to every session and 3,359 once invoked, about $0.0004 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.
