Extract duplicate MCP bridge initialization code from codexLocalLauncher and
codexRemoteLauncher into a new buildHapiMcpBridge utility. This ensures both
modes use identical server setup logic and provides a single source of truth
for MCP configuration.
Update codexStartConfig to deliver system prompt via developer_instructions
instead of appending to the user message. This ensures consistent behavior
between local and remote modes and properly separates system guidance from
user intent.
Implements MCP server configuration and developer instructions support in
Codex local mode, bringing it to parity with remote mode.
Key additions:
- buildMcpServerConfigArgs() and buildDeveloperInstructionsArg() utilities
to construct -c config arguments for passing MCP servers and instructions
to the Codex CLI at runtime
- TITLE_INSTRUCTION for Codex to call hapi__change_title to update chat
session titles dynamically
- Codex local mode now starts hapi MCP bridge server and passes both MCP
configuration and developer instructions to Claude, enabling full feature
parity with remote mode
Files changed:
- New: codexMcpConfig.ts (utilities), systemPrompt.ts (prompt definition),
codexMcpConfig.test.ts (comprehensive tests)
- Updated: codexLocal.ts (accepts mcpServers, builds config args),
codexLocalLauncher.ts (starts hapi server, passes config),
codexStartConfig.ts (imports TITLE_INSTRUCTION)
Create BaseSessionScanner abstract class to consolidate common session
scanning logic shared between Claude and Codex session scanners. Both
scanners now inherit from this base, reducing duplication and providing
consistent patterns for file watching, event processing, and state
management.
Add sendUserMessage() method to ApiSessionClient and CodexSession to handle
user_message events from Codex. Updates CodexConversionResult type and
convertCodexEvent() to process user_message payloads, with test coverage.
This refactoring introduces CLI argument overrides for sandbox and approval policy settings in remote mode, allowing users to specify security constraints via `--sandbox` and `--ask-for-approval` flags.
Changes:
- Add `CodexCliOverrides` type and `parseCodexCliOverrides()` utility to parse CLI flags like `--sandbox`, `-s`, `--ask-for-approval`, `-a`, along with convenience flags (`--full-auto`, `--dangerously-bypass-approvals-and-sandbox`)
- Extract complex start config building logic into `buildCodexStartConfig()` function with proper approval policy and sandbox resolution based on permission mode
- Thread `codexCliOverrides` through the session/loop/launcher chain and apply overrides only when permission mode is 'default'
- Update `codexRemoteLauncher` to use the new config builder and display appropriate warnings based on whether overrides are present
- Add comprehensive tests for both parsing and config building functions
Reorganized runCodex.ts to improve maintainability by extracting:
- CodexSession class for session lifecycle management
- CodexLocalLauncher and CodexRemoteLauncher for mode-specific initialization
- CodexEventConverter for MCP message handling and UI buffer updates
- CodexSessionScanner for resume file discovery
- emitReadyIfIdle utility for ready event emission
Added codexSessionId field to metadata schema for session tracking.
Updated UI components to work with refactored architecture.
