patch-edit

patch-edit is a skill for Claude Code, Codex from wolfenazz/YzPzCode. It costs 30 tokens per session (453 once invoked), scanned A, original, Apache-2.0.

A workflow skill that applies one planned code change at a time as a small, localised file edit. It records whether each step was completed or skipped and keeps a receipt of the change.

In plain words
What is it for?
It helps carry out multi-step code migrations or refinements while tracking progress and the files changed.
Why use it?
It makes code changes easier to review and avoids large rewrites that can hide unrelated mistakes.

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-edit 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.

What it actually says

Patch edit

Spec §20.3 / §21.3.2: code-migration / tune-collab cannot ship a trustworthy diff when the agent rewrites whole files in one pass — the reviewer can't audit the change. This atom enforces "one step per turn, smallest possible localised edit".

Inputs

  • plan/steps.json from rewrite-plan.
  • The current value of iterations (the daemon's per-stage counter).
  • code/index.json for the file's known imports + neighbours.

Output

The atom mutates files inside the project cwd via the file-edit tool. After every iteration, it writes a per-step receipt:

project-cwd/
└── plan/
    ├── steps.json (status updated: 'pending' → 'completed' | 'skipped')
    └── receipts/
        └── step-<id>.json    # { files: ['...'], diffSummary, rationale, completedAt }

Convergence

The atom completes when every step in plan/steps.json is in a terminal state (completed / skipped) OR iterations >= OD_MAX_DEVLOOP_ITERATIONS. Use:

{
  "id": "patch-edit-loop",
  "atoms": ["patch-edit"],
  "repeat": true,
  "until": "plan.steps.terminal === plan.steps.total || iterations >= 8"
}

Anti-patterns the prompt fragment forbids

  • Rewriting an entire file when the rewrite-plan step is localised.
  • Touching a file outside the step's files[].
  • Touching a shell-tier file when the step's risk is not 'high' or the user hasn't confirmed.
  • Skipping a step without a receipt + a rationale string.

Status

Reserved id, prompt-only fragment in v1.

Files

What ships with it

1 file 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.
