patch-diff-mode

patch-diff-mode is a skill for Claude Code, Codex from cembasaranoglu/crafting-system-claude. It costs 17 tokens per session (79 once invoked), scanned A, original, MIT.

A workflow for making only the smallest necessary code change and showing it as a patch or diff.

In plain words
What is it for?
It supports tasks where the required output is a minimal patch rather than a broad rewrite.
Why use it?
It helps keep changes focused and makes them easier to inspect, review, and apply safely.

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

patch-diff-mode 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 yesterday.

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

patch-diff-mode

Use source-first, evidence-led execution. Separate facts, assumptions, recommendations, unknowns, blockers, not-run, failed, and validated. Do not claim validation or mutate external systems unless explicitly authorized. Produce named artifacts and cite source paths when possible.

Files

What ships with it

4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
