mbun: Skill for Claude Code

.agents/skills/dev-process/SKILL.md

dev-process is a skill for Claude Code, Codex from Sunrisepeak/mbun. It costs 82 tokens per session (1,330 once invoked), scanned A, original, no licence file.

A development process for changes in the repository, dividing work into bug fixes, optimisations, and new features. New features require prior issue discussion and a written design in .agents/docs, followed by testing, validation, continuous integration, and pull-request checks.

In plain words
What is it for?
Use it before developing any change, especially a new feature, and alongside the repository's testing and review workflow.
Why use it?
It gives each change a defined path and records the reasoning before implementation begins.

Which agent this was written for is unclear — body not stored (licence); the path alone says nothing. Also seen: installed under .agents/ (shared by several agents).

This is Sunrisepeak/mbun's own configuration. It tells Claude Code and Codex how to work on mbun itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything mbun configures →

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-process 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 2mo 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.

The source is not reproduced here

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

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.
