v2.6.0 - Plugin Support, Stability Improvements

Highlights

🔌 Claude Code Plugin Support

Load plugins from .claude/plugins/ - full compatibility with Claude Code's plugin ecosystem.

🧠 Dynamic Context Pruning (DCP)

No more abrupt compactions. When context runs low, DCP intelligently prunes before falling back to full compaction:

Each stage runs independently. If one stage frees enough tokens, later stages are skipped.

Protected by default: todowrite, lsp_rename, session_* and more.
Configurable: notification level, turn protection, per-strategy toggles.

Result: Longer sessions, better context retention, fewer forced compactions.

⚡ Sisyphus as Default Agent

When omoSisyphus.enabled: true, Sisyphus automatically becomes your default agent - no manual configuration needed.

🛡️ Two-Layer Thinking Validation

Proactive + reactive validation ensures thinking blocks are always valid and properly formatted.

📝 JSONC Config Support

Comments in your config files! Both oh-my-opencode.json and oh-my-opencode.jsonc now support JSON with Comments.

Fixes

• Windows file URL compatibility in look_at tool
• notify-send command existence check before calling
• CLAUDE_CONFIG_DIR environment variable support
• Dynamic truncator fallback when context usage unavailable
• Config error toast deferred to session.created for TUI readiness
