Evil OpenCode Reasonix

This repo builds a release pipeline on top of winmin/evil-opencode.

It does three things:

• watches winmin/evil-opencode releases
• resolves the matching source state or falls back to upstream OpenCode when needed
• applies a Reasonix cache-preservation patch layer before building and releasing

It now also materializes a CodexPro companion layer for oh-my-openagent users:

• generates an OMO-compatible .mcp.json entry for codexpro-mcp
• pins CodexPro support to 0.28.5
• uses CodexPro full mode so codex_context is available
• configures CodexPro with write=handoff and bash=off by default

In CodexPro full mode those restrictions are enforced at tool-call time; they do not remove write, edit, or bash from the advertised full-mode tool catalog.

Cache Audit

Live upstream research found three cache-hit behaviors that matter for current OpenCode-based releases:

• OpenAI Responses multi-turn continuity via persisted previous_response_id
• broader promptCacheKey wiring for SDK-based OpenAI and GitHub Copilot providers
• cache-aligned compaction so the compaction request reuses the same cached prefix as the main loop

The current winmin/evil-opencode v1.17.11-unguarded release already carries basic prompt-cache markers, but it does not include all of the later cache-hit behavior above. This repo patches those missing behaviors in a release-safe second layer.

Validation

Local validation:

npm test

Live validation performed against winmin/evil-opencode v1.17.11-unguarded:

• source resolution succeeds
• Reasonix patch application succeeds
• CodexPro integration assets generate successfully
• release verification succeeds
• patched packages/opencode passes bun run --cwd packages/opencode typecheck
