Features on main

Synara main currently contains a large post-0.5.5 development batch. The public documentation tracks the user-facing parts without presenting them as stable release behavior.

Agent Gateway and app control

The Synara Agent Gateway adds an app-owned MCP tool surface for supported provider sessions. It gives capable agents controlled access to Synara tasks, projects, task state, steering, diagnostics, and selected automation operations.

Gateway-created tasks are normal top-level Synara tasks. Provider-native subagents remain child sessions and do not silently become Synara resources.

External MCP integrations

Under Settings → Integrations, main can expose a scoped Synara tool surface to outside MCP apps — Codex, Claude Code, Claude Desktop, or any other MCP client — through a guided pairing flow: copy the pairing command, paste it in a terminal, and the integration moves through Paired → Connected. Synara generates the exact claude mcp add / codex mcp add command for you.

Paired apps get tools like synara_capabilities, synara_list_allowed_projects, synara_create_task, synara_wait_for_task, and synara_read_task. Safe defaults apply — managed worktrees and approval-required — with higher-impact scopes behind Advanced permissions. Connections are loopback-only, with revocable per-integration credentials.

Project spaces

Threads can be organized into named spaces per project, with a space switcher tab bar and space-aware orchestration. Keyboard: mod+alt+← / mod+alt+→ switch spaces, mod+alt+1…9 jump directly.

Native subagents and workflows

Claude subagents and dynamic workflows now receive richer first-class presentation: subagents appear as child threads with their own usage meters, and a workflow run card above the composer shows live agent rows, workflow phases, and pause/resume/stop controls. The composer includes a /subagents workflow for explicitly requesting parallel delegation.

Smaller preview changes

• The AppSnap global capture shortcut is user-configurable in settings.
• On macOS, sidebar search is cmd+k and ctrl+k is freed for other bindings.
• Interrupted worktree cleanup recovers automatically; reverting a checkpoint is rejected while a turn is active.

Provider and model updates

• Pi model discovery includes newly available Claude Fable 5 and Claude Opus 4.8 entries when the authenticated provider catalog returns them.
• Namespaced Cursor Grok ACP model identifiers are supported.
• Provider model choices are prefetched to make new-task creation faster.
• Provider update paths preserve the configured global package prefix more reliably.

Performance and reliability

The post-release work reduces first-turn latency, moves independent startup and turn I/O into parallel paths, cuts repeated streaming persistence work, and improves recovery around provider commands, approvals, sessions, attachments, and interrupted gateway operations.

Interface changes

The sidebar prioritizes live tasks, cross-task labels are clearer, agent activity has stronger hierarchy, workflow cards show their phases more directly, and model/effort controls have been consolidated around the composer.

Canary workflow for contributors

Contributors can build an isolated Synara Canary from a selected remote Git ref. Canary uses its own app identity, data directory, Electron profile, source checkout, logs, and update path, so it can run beside Stable or a development instance without sharing user data.

See the repository's docs/canary.md for the current setup, update, rollback, and isolation commands.
