patpat-change

patpat-change is a skill for Cursor from goiltpatpat/patpat. It costs 38 tokens per session (568 once invoked), scanned A, original, MIT.

A workflow for implementing one clearly defined repository change with a small, focused diff and explicit checks. It is intended for known features, localized refactors, and fixes whose cause or design is already understood.

In plain words
What is it for?
Use it to add a feature, make a focused refactor, fix a known defect, or perform a behavior-preserving rename or extraction. It can include test-first work and visual comparison when requested.
Why use it?
It keeps implementation bounded and reduces unrelated cleanup, speculative abstractions, and accidental interface changes. It also requires evidence appropriate to the changed behavior before calling the work complete.

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

patpat-change 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 4d 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.

Patpat Change

For clear, bounded, reversible local work without delivery intent, use this skill and its relevant references. Otherwise read the operating protocol and execution graph in full before acting. Escalate on uncertainty, security, auth, billing, secrets, architecture, cross-cutting work, or delivery intent. Do not load the router or reread unchanged instructions already loaded in this session.

Read smallest safe change, preserve safety, and proof over proxy. Apply the bounded change playbook.

For a behavior-preserving rename, move, extraction, inline, or deduplication, apply the behavior-preserving refactor playbook. When the user requests test-first work or a cheap deterministic regression target exists, apply regression first.

When regression-first applies, observe fail-before (or an explicit why-not) and report fail-before and pass-after on the same check; do not silently skip.

For an explicit visual migration or pixel-equivalence claim, apply the visual equivalence playbook without weakening its baseline or comparison harness.

Inspect version-control state and nearby contracts before editing. Define Claim, Surface, Action, Expect, and Cleanup. Make one coherent repository-native patch. Avoid unrelated cleanup, speculative abstractions, new dependencies, and public interface changes unless the objective requires them.

Do not claim completion from generation, compilation, or tests alone when the changed behavior has an observable surface.

Proof closure

Define the five-field proof contract before any mutation. Close mutating work with:

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.

patpat-change is a skill published in the GitHub repository goiltpatpat/patpat (1 stars, last pushed yesterday), licensed MIT. It adds 38 tokens to every session and 568 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 2026-08-31.
