v2026.222.1

What's Changed

Bug Fixes

• Claude Code adapter: Added --dangerously-skip-permissions, --verbose, --output-format stream-json flags for proper pipe-mode execution
• Token parsing: Fixed nested message.usage handling + cache token counting (cache_read_input_tokens + cache_creation_input_tokens)
• Agent-commit detection: commitSandboxChanges() now diffs against origin/<baseBranch> to detect all changes, including those committed directly by the agent (previously showed filesChanged: 0)
• Commit message: Fixed hardcoded "Codex CLI" → "OAC"
• Availability check: Added stdin: 'ignore' to Claude Code checkAvailability() to prevent hanging

Verified

• Dogfood tested: OAC successfully contributed PR #27 to itself via Claude Code
• 369/369 tests passing

v2026.221.1

Changes

• fix: Refine Codex JSONL envelope parsing for item.completed events (file_change + command_execution types)
• fix: Updated Codex adapter test assertions
• chore: Refreshed .oac/context/ files from OAC self-contribution run

v2026.220.2

What's New

Multi-user Concurrency Protection (Phase 1)

• Layer 1: Discovery-time filter — issues with existing [OAC] PRs are automatically skipped
• Layer 3: Pre-PR duplicate guard — final check before creating PRs prevents duplicates
• Both layers fail silently (fail-open) to avoid blocking the pipeline

Config Loader Fix

• Handle ERR_UNKNOWN_FILE_EXTENSION on Node < 22.6 (data-URL fallback now triggers correctly)
• Match both @open330/oac and @open330/oac-core imports in config files

Reviews

• Round 5/9 reviews from 6 personas (Arch 9.8, Quality 9.5, Perf 9.5, Security 9.3, Perf-Opt 9.5, UX 10)

Full Changelog: v2026.220.1...v2026.220.2

v2026.4.4 — Config Loader Bug Fix

Bug Fix

• fix: config-loader regex now matches @open330/oac import — After running oac init, the generated config uses import { defineConfig } from "@open330/oac". The fallback regex in config-loader.ts only matched @open330/oac-core and @oac/core, so oac run couldn't read the config and threw "No repository specified." Fixed by updating the regex to @open330/oac(?:-core)?.

What's New Since v2026.4.3

• OpenCode provider integration (adapter + registry)
• 7 pre-existing typecheck errors fixed
• Utility consolidation (truncate, isRecord → core/utils.ts)
• CI actions SHA-pinned + pnpm audit added
• Empty catch blocks annotated
