ContextForge

Purpose

ContextForge helps engineering teams create reusable AI context for Cursor, Claude Code, Codex, Windsurf, and other AI IDEs.

Use this skill to guide AI agents with project-specific architecture, coding standards, domain knowledge, business rules, reusable prompts, and implementation constraints.

When to Use

Use this skill when the user wants to:

Create a reusable AI skill
Convert requirements into structured context
Generate SKILL.md, rules.md, domain.md, or agents.md
Build context packs for AI IDEs
Standardize AI-assisted development across a team
Reduce repeated prompting and token waste
Maintain consistent architecture and coding practices

Core Concepts

Skill

A reusable instruction file that teaches an AI agent how to perform a specific task.

Rule

A strict engineering or business constraint that must always be followed.

Domain

Business vocabulary, entities, workflows, invariants, and bounded context.

Agent

Role-based behavior for AI assistants, such as reviewer, architect, tester, or refactor agent.

Context Pack

A bundled set of skills, rules, domains, and agent instructions that can be reused across projects.

Operating Rules

Always understand the target project before generating context.
Keep instructions specific, actionable, and reusable.
Avoid generic advice that does not improve agent behavior.
Separate business rules from technical implementation rules.
Keep domain language consistent across all files.
Prefer markdown files that can be used directly inside AI IDEs.
Optimize context for clarity, token efficiency, and maintainability.

Output Format

When generating a context pack, produce:

context-pack/
  SKILL.md
  rules.md
  domain.md
  agents.md
