arnesto: Skill for Cursor

.cursor/skills-cursor/split-to-prs/SKILL.md

split-to-prs is a skill for Cursor from saski/arnesto. It costs 34 tokens per session (524 once invoked), scanned A, a copy of split-to-prs, Unlicense.

An instruction for dividing a large set of code changes into several small pull requests. A pull request is a proposed change submitted for review before merging.

In plain words
What is it for?
Inspecting changed files, proposing reviewable slices, and preparing a safe split plan before branches, commits, or pull requests are created.
Why use it?
Smaller pull requests are easier to review and reduce the risk of mixing unrelated work.

Skill for Cursor

This is saski/arnesto's own configuration. It tells Cursor how to work on arnesto itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything arnesto configures →

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

split-to-prs 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 3d 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.

Split to PRs

Turn one pile of work into a few small PRs.

Hard rules

  • Do not create branches, commit, push, or open PRs until the user approves the split plan.
  • Never discard user work. No destructive git commands (reset --hard, clean -fdx, branch deletion, force-push, history rewrite) without explicit approval.
  • Always save a recoverable snapshot before moving work around. This often starts from dirty work on main, so do not assume there is already a safe branch.
  • Stage only named files or hunks. No git add . / git add -A.

1. Check the state

Compare the current work to the repo's default branch, including committed and uncommitted changes. Summarize the real slices you see, and use the chat history to recover intent.

Before proposing slices, find ownership signals for the touched paths (CODEOWNERS, nested ownership files, tools/ownership/PRODUCTOWNERS, or repo equivalents) and use them to identify natural reviewer boundaries.

2. Propose the split

Use judgment on detail. Usually PR titles are enough. Add a one-line scope note only when a title is unclear. Show a Mermaid diagram when there are multiple slices.

Optimize for reviewer-aligned PRs with minimal unrelated diff: split independent owners or concerns, keep tightly coupled changes together, and when stacking is necessary, order foundations before consumers.

Default to independent PRs off the default branch. Stack PRs only when the dependency is real.

Ask for approval before starting.

3. Execute the split

  • If there is uncommitted work, save a recoverable snapshot without changing the working tree:

    SHA=$(git stash create "pre-split")
    if [ -n "$SHA" ]; then
      git update-ref "refs/backup/pre-split-$(date +%s)" "$SHA"
    fi
    
  • For each approved slice, create a branch from the right base, stage and commit only the planned files or hunks, then push and open the PR.

4. Report back

Keep it short: PR titles and URLs, plus anything left on the starting branch or working tree. Do not delete the backup ref or original branch unless the user asks.

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.
