patpat-perf

patpat-perf is a skill for Cursor from goiltpatpat/patpat. It costs 45 tokens per session (344 once invoked), scanned A, original, MIT.

A performance-testing guide for finding and fixing slowdowns or other measurable resource problems in software.

In plain words
What is it for?
Use it to improve latency, CPU use, memory use, throughput, startup time, or another numeric performance target.
Why use it?
It replaces guesswork with comparable before-and-after measurements, helping identify the real main cost without weakening correctness or safety.

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-perf 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 10d 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.

What it actually says

Patpat Performance

When invoked directly, read the operating protocol and execution graph in full. Do not load the router.

Read proof over proxy, fix root causes, and smallest safe change. Apply the performance playbook.

Measure the reported surface before reading toward a preferred cause. Keep workload, environment, warm-up, sample policy, and units comparable. Locate the dominant cost, change one causal variable, and preserve correctness and safety invariants.

When the objective requires sustained improvement toward a numeric target rather than one regression fix, apply the metric hillclimb playbook through patpat-run.

Report the baseline, post-change result, measurement noise, artifact locations, and remaining tradeoffs. Do not claim improvement from a single incomparable or proxy measurement.

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.

patpat-perf is a skill published in the GitHub repository goiltpatpat/patpat (1 stars, last pushed yesterday), licensed MIT. It adds 45 tokens to every session and 344 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.
