dotPilot: Skill for Codex

.codex/skills/mcaf-source-control/SKILL.md

mcaf-source-control is a skill for Codex from managedcode/dotPilot. It costs 50 tokens per session (798 once invoked), scanned A, a copy of dotnet-mcaf-source-control, MIT.

A source-control policy guide covering branches, pull requests, merges, releases, repository structure, and keeping secrets out of Git. Git is the system commonly used to track code changes.

In plain words
What is it for?
Use it when creating or tightening branching rules, merge and pull-request processes, commit hygiene, release policy, or secret-handling rules.
Why use it?
It removes uncertainty about how changes move through a repository and helps prevent unsafe handling of credentials or inconsistent release practices.

Skill for Codex

Written for Codex: installed under .codex/. Also seen: mentions AGENTS.md.

This is managedcode/dotPilot's own configuration. It tells Codex how to work on dotPilot 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 dotPilot 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

mcaf-source-control 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 3d 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.

Origin

This is a copy

95% identical to dotnet-mcaf-source-control — 4 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

MCAF: Source Control

Trigger On

  • bootstrapping source-control policy
  • tightening branch, merge, or PR rules
  • documenting commit or release hygiene
  • dealing with secrets-in-git or repository structure issues

Value

  • produce a concrete project delta: code, docs, config, tests, CI, or review artifact
  • reduce ambiguity through explicit planning, verification, and final validation skills
  • leave reusable project context so future tasks are faster and safer

Do Not Use For

  • CI/CD workflow design with no source-control policy change
  • one-off git commands that do not alter repo policy

Inputs

  • current branching and merge flow
  • release strategy and versioning expectations
  • secret-handling and repository-structure constraints

Quick Start

  1. Read the nearest AGENTS.md and confirm scope and constraints.
  2. Run this skill's Workflow through the Ralph Loop until outcomes are acceptable.
  3. Return the Required Result Format with concrete artifacts and verification evidence.

Workflow

  1. Agree on merge and release strategy before scaling implementation.
  2. Keep branch and PR rules explicit in-repo.
  3. Treat secrets in git history as a critical incident, not cleanup noise.
  4. Use concrete policy language, not hand-waving.

Deliver

  • clear branch and merge strategy
  • updated contribution or governance docs
  • safer repository hygiene around commits, PRs, and secrets

Validate

  • naming and merge rules are explicit
  • release/versioning implications are documented where needed
  • secret hygiene is treated as policy, not tribal knowledge

Ralph Loop

Use the Ralph Loop for every task, including docs, architecture, testing, and tooling work.

  1. Brainstorm first (mandatory):
    • analyze current state
    • define the problem, target outcome, constraints, and risks
    • generate options and think through trade-offs before committing
    • capture the recommended direction and open questions
  2. Plan second (mandatory):
    • write a detailed execution plan from the chosen direction
    • list final validation skills to run at the end, with order and reason
  3. Execute one planned step and produce a concrete delta.
  4. Review the result and capture findings with actionable next fixes.
  5. Apply fixes in small batches and rerun the relevant checks or review steps.
  6. Update the plan after each iteration.
  7. Repeat until outcomes are acceptable or only explicit exceptions remain.
  8. If a dependency is missing, bootstrap it or return status: not_applicable with explicit reason and fallback path.

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.
