charset=UTF-8 Content-Transfer-Encoding: 8bit Resolves Issue #25 - Plugin fails with confusing errors if started with the other oauth plugin's cache files **Root Cause**: Both opencode-openai-codex-auth and @openhax/codex plugins used identical cache file names in ~/.opencode/cache/, causing conflicts when switching between plugins. **Solution**: 1. **Cache Isolation** (lib/utils/cache-config.ts): - Added PLUGIN_PREFIX = "openhax-codex" for unique cache namespace - Updated cache files to use plugin-specific prefixes: - openhax-codex-instructions.md (was codex-instructions.md) - openhax-codex-opencode-prompt.txt (was opencode-codex.txt) - Corresponding metadata files with -meta.json suffix 2. **Migration Logic** (lib/prompts/opencode-codex.ts): - migrateLegacyCache(): Automatically detects and migrates old cache files - validateCacheFormat(): Detects incompatible cache formats from other plugins - Enhanced error messages with actionable guidance for cache conflicts 3. **Test Updates**: - Updated all test files to use new cache file names - All 123 tests passing ✅ **User Experience**: - Seamless migration: Users switching plugins get automatic cache migration - Clear error messages: When cache conflicts occur, users get actionable guidance - No data loss: Existing cache content is preserved during migration Files modified: - lib/utils/cache-config.ts - Cache isolation configuration - lib/prompts/opencode-codex.ts - Migration and validation logic - test/prompts-opencode-codex.test.ts - Updated cache file paths - test/prompts-codex.test.ts - Updated cache file paths - spec/issue-25-oauth-cache-conflicts.md - Implementation spec --- lib/prompts/opencode-codex.ts | 110 +++++++++++++++-- lib/utils/cache-config.ts | 27 ++++- spec/issue-25-oauth-cache-conflicts.md | 158 +++++++++++++++++++++++++ test/prompts-codex.test.ts | 4 +- test/prompts-opencode-codex.test.ts | 5 +- 5 files changed, 289 insertions(+), 15 deletions(-) create mode 100644 spec/issue-25-oauth-cache-conflicts.md diff --git a/lib/prompts/opencode-codex.ts b/lib/prompts/opencode-codex.ts index a66bb0f..8b7162c 100644 --- a/lib/prompts/opencode-codex.ts +++ b/lib/prompts/opencode-codex.ts @@ -3,13 +3,14 @@ * * Fetches and caches codex.txt system prompt from OpenCode's GitHub repository. * Uses ETag-based caching to efficiently track updates. + * Handles cache conflicts when switching between different Codex plugins. */ -import { mkdir, readFile, writeFile } from "node:fs/promises";
