ContextForge
Turn any repository into an AI-ready context pack — AGENTS.md, .cursorrules, CLAUDE.md.
Paste a file tree and ContextForge writes the instruction files every coding agent reads: AGENTS.md, .cursorrules, CLAUDE.md, .github/copilot-instructions.md and GEMINI.md. A deterministic extractor infers package manager, framework, test runner, CI, entry points and build/test/lint commands and tags each fact as detected or inferred; an optional model-assisted pass turns those facts into prose. If the model is unavailable it degrades to a labelled rule-based draft and never fakes AI output. A Context Score (0-100) plus an open-questions list shows exactly what the input could not determine.

Who is ContextForge for?
Solo founders, indie hackers and small teams who want a narrow, ready-to-use developer tools capability without building it from scratch.
How does ContextForge work?
Turn any repository into an AI-ready context pack — AGENTS.md, .cursorrules, CLAUDE.md.
When to do this manually
ContextForge does one thing well: Turn any repository into an AI-ready context pack , AGENTS.md, .cursorrules, CLAUDE.md. A complete context pack still does not guarantee correct AI output - review what the pack includes before you rely on it.

Pricing starts at $19/mo. See the live tool for the current plan and any free tier.
Who is ContextForge for?
ContextForge is built for operators and builders shipping content who need this exact job done: Turn any repository into an AI-ready context pack , AGENTS.md, .cursorrules, CLAUDE.md.
What inputs does ContextForge struggle with?
Not a replacement for reading the code yourself. A context pack organises what already exists; it cannot tell you whether the code is any good.
