feat: Multi-Platform Support - Cursor & Codex

[DanielPodolsky]

The Ask

"Can OwnYourCode work with Cursor?"
— Actual user request

OwnYourCode currently targets Claude Code specifically. Developers use other agentic tools and shouldn't be locked out.

---

Target Platforms (Phase 1)

Platform	Type	Why First
Cursor	AI-native IDE	Massive adoption, has rules system
Codex (OpenAI)	CLI/API agent	Growing ecosystem, different architecture

---

Research Phase (Before Implementation)

We need to understand how similar projects implement cross-platform support.

Research Tasks

• Cursor: How do .cursorrules and project-level rules work?
• Cursor: Find 3-5 repos with sophisticated Cursor rules and analyze patterns
• Codex: What's the instruction/customization format?
• Codex: How do other projects inject methodology into Codex?
• Cross-platform projects: Find projects that support BOTH Claude Code AND Cursor, study their approach
• File format mapping: CLAUDE.md → .cursorrules → Codex equivalent

Research Output

A document answering:

1. What's the instruction format for each platform?
2. What features translate across platforms? What doesn't?
3. What's the recommended architecture for multi-platform support?

---

Implementation (After Research)

Proposed Approach

# User chooses platform during install
~/ownyourcode/scripts/project-install.sh --platform cursor
~/ownyourcode/scripts/project-install.sh --platform codex
~/ownyourcode/scripts/project-install.sh --platform claude  # default

Generates platform-appropriate files from same core methodology.

Community Help Wanted

Do you use Cursor or Codex? We need:

1. How custom instructions work on your platform
2. Example of a working instruction file
3. Links to projects with good platform-specific setups

+1, also Antigravity may be a good addition. Porting should be fairly easy, but can also be augmented by existing cross-platform tools like Skillshare

Thanks @atreydesai, I'll check it out!
