sdlc-quality copilot-instructions.md

Repository guidance for GitHub Copilot when working on the `sdlc` plugin. SDLC means software development life cycle: the stages used to plan, build, test, and maintain software.

In plain words
What is it for?
It helps Copilot navigate the repository and follow its software-quality rules, including RFC 2119 terms such as MUST and SHOULD.
Why use it?
It gives the coding assistant the project structure, conventions, and required wording for quality-related work.

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

sdlc-quality copilot-instructions.md 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.

Copilot Instructions for sdlc plugin

This document provides guidance for GitHub Copilot when working with the sdlc plugin repository.

Project Overview

Plugin Name: sdlc

The sdlc plugin is a Claude Code plugin that provides comprehensive Software Development Lifecycle standards guidance. It works with any AI coding assistant (Claude, Gemini, Codex, Copilot, OpenCode, etc.) and codifies project quality requirements across the entire software development lifecycle.

Key Conventions

RFC 2119 Terminology

This project uses RFC 2119 compliance levels:

  • MUST: Mandatory requirement. Non-compliance blocks release.
  • SHOULD: Strong recommendation. Should be followed unless there's good reason not to.
  • MAY: Optional enhancement. Nice to have.

SDLC Domains

The plugin covers 11 domains:

  1. build - Build system configuration (Makefile, dependencies)
  2. quality - Code formatting, linting, error handling
  3. testing - Test organization, coverage, patterns
  4. ci - CI/CD pipeline configuration
  5. security - Vulnerability scanning, supply chain, secrets
  6. docs - Documentation requirements (README, CHANGELOG, ADRs)
  7. vcs - Version control practices (git, branching, commits)
  8. release - Semantic versioning, release automation
  9. observability - Logging, metrics, health checks
  10. ai - AI coding assistant context configuration
  11. setup - Project initialization and scaffolding

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.
