dev-small-scope-patch

A set of rules for making small, local changes to code, documentation, configuration files, or tests.

In plain words
What is it for?
Use it when a coding task has a clear scope and should follow the project's existing patterns while leaving other uncommitted work untouched.
Why use it?
It helps prevent unrelated refactoring and changes that could affect parts of the system outside the task.

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

dev-small-scope-patch 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

DEV Small Scope Patch

When to use

Use when implementation is authorized and scope is clear.

Rules

  • Keep edits small and local.
  • Follow project patterns.
  • Preserve unrelated dirty work.
  • Explain non-goals.

Required output

Use docs/skills/dev-playbook/small-scope-patch.md.

Forbidden actions

  • Do not perform drive-by refactors.
  • Do not modify formal FCoP protocol unless explicitly tasked.
  • Do not add Panel/API/runtime behavior from a Playbook task.

Minimal example

File: skills/README.md
Change: add new skill group list
Why: keep catalog discoverable
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.
