Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.01255 | $0.01255 |
| Opus 5 | $0.00628 | $0.00628 |
| Sonnet 5 | $0.00251 | $0.00251 |
| Haiku 4.5 | $0.00126 | $0.00126 |
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.
How it starts
The opening of the file, as written. The whole thing — 160 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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:
- build - Build system configuration (Makefile, dependencies)
- quality - Code formatting, linting, error handling
- testing - Test organization, coverage, patterns
- ci - CI/CD pipeline configuration
- security - Vulnerability scanning, supply chain, secrets
- docs - Documentation requirements (README, CHANGELOG, ADRs)
- vcs - Version control practices (git, branching, commits)
- release - Semantic versioning, release automation
- observability - Logging, metrics, health checks
- ai - AI coding assistant context configuration
- 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.

sdlc-quality copilot-instructions.md is an instructions file published in the GitHub repository zircote-plugins/sdlc-quality (10 stars, last pushed 1mo ago), licensed MIT. It adds 1,255 tokens to every session, about $0.0063 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
