Problem-Based-SRS: Instructions file for Codex

AGENTS.md

Problem-Based-SRS AGENTS.md is an instructions file for Codex, OpenCode from RafaelGorski/Problem-Based-SRS. It costs 1,108 tokens per session, scanned A, original, MIT.

Repository instructions for Problem-Based Software Requirements Specification, a method for describing the user problem and requirements before deciding on a software solution. It guides AI coding assistants, especially GitHub Copilot and Claude Code, through requirements work.

In plain words
What is it for?
Use it to explore a problem, write or evolve software specifications, design new systems, and plan changes to existing systems.
Why use it?
It helps prevent code being produced before the underlying problem is understood and keeps requirements traceable as an existing system changes.

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

Problem-Based-SRS AGENTS.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 1mo 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.

GitHub Copilot Instructions for Problem-Based SRS

Project Overview

Problem-Based SRS is a plugin that extends your AI harness to handle Software Specifications. It plugs into GitHub Copilot first — and Claude Code and other AI coding assistants too — turning a general-purpose coding agent into one that can reason about, trace, and evolve requirements instead of only emitting code. On top of the harness it adds three things: AI‑slop prevention tuned to the specific model, a spec language and command palette that steer toward great design, and a rigorous method to evolve existing (brownfield) systems as well as build new ones.

The plugin delivers this through AgentSkills for a Problem-Based Software Requirements Specification (SRS) methodology, enabling AI-assisted requirements engineering through structured, problem-first approaches.

The repository follows the AgentSkills standard and the Claude Code Plugins layout. Compatibility priority is GitHub Copilot first, then Claude Code/Claude.ai.

Core Principles

  1. Problem-First Thinking: Always identify the problem before proposing solutions
  2. Lightweight Methodology: Favor simplicity over complex frameworks
  3. AI-Native Design: Content designed for consumption by AI agents (following AgentSkills standard)
  4. Practical Guidance: Focus on actionable skills and templates

Compatibility Priority (GHCP → Claude)

  • GitHub Copilot first: Keep skills and instructions directly usable in Copilot workflows.
  • Claude second: Keep .claude-plugin/plugin.json, skills/, agents/, and settings.json aligned with Claude plugin docs.
  • Consistency over time: Keep compatibility guidance consistent when it changes.

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.
