opencode-x v1.0.8

v1.0.8 is a large feature release with new agent workflows, Claude Code agent support, research tooling, checkpointed long-session memory, stronger provider compatibility, improved MCP/LSP behavior, and many TUI quality-of-life fixes.

Highlights

• Claude Code agent support: native support for Claude Code-style agent definitions, gated for safe rollout.
• Workflow engine: QuickJS-powered workflow system for scripted multi-agent automation.
• Research mode: new research tool and /research command for deeper investigation flows.
• Long-session checkpoints: checkpoint writer helps rebuild useful context after compaction.
• Smarter providers: OpenAI response chaining, cache retention, truncation support, stricter schema handling, and generic reasoning_options support.
• Better MCP/LSP: MCP roots/capabilities, local server cwd, structured tool output, and multi-root LSP diagnostics.
• TUI upgrades: transcript search, notification queue, OSC-8 links, workflow status, and editor chord fixes.

New features

Claude Code agents

• Added native Claude Code agent definition support.
• Integrated agent loading into opencode-x agent registry.
• Added feature gate for controlled Claude plugin agent rollout.

Workflows

• Added QuickJS sandboxed workflow engine for deterministic automation.
• Added workflow discovery from .opencode/workflows/ and ~/.config/opencode/workflows/.
• Added sample workflows: implement.js, review-and-fix.js, test-debug-loop.js, test.js.
• Added /workflow TUI command with create/start/list/stop flows.
• Added workflow status UI with running/waiting/agent-started states.
• Added crash-recovery journal support, concurrency limits, depth limits, and graceful shutdown.

Research

• Added research tool and /research command.
• Added command/docs support for research-oriented workflows.

Long-session checkpoints

• Added checkpoint system for long session context rebuild.
• Checkpoint writer summarizes session state into structured files before compaction.
• Added checkpoint boundary tracking in database.
• Added checkpoint writer agent prompt.
• Added rebuild context injection after compaction.
• Improved checkpoint reliability by writing files programmatically instead of relying on agent file tools.

Dream/distill self-improvement

• Added dream/distill prompt system.
• Added configurable dream/distill context limits.
• Added automatic dream/distill trigger support.
• Improved context extraction to include all text messages within configured limits.
• Raised distill quality bar to skip trivial patterns.

Provider capabilities

• Added OpenAI response chaining through previousResponseId.
• Added OpenAI Responses API options: promptCacheRetention, truncation.
• Added generic provider support through reasoning_options.
• Added schema compatibility support for stricter providers.
• Improved reasoning/tool/schema behavior across future model registry updates.

MCP and LSP

• Added MCP client capabilities declaration, roots support, local server cwd, and structured tool output handling.
• Added MCP tool filtering documentation and examples.
• Added multi-root LSP workspace support for cross-project diagnostics.
• LSP clients can now add workspace folders dynamically when agents touch external project files.
• Diagnostics are filtered to agent-opened files to avoid flooding.
• Improved TypeScript, Deno, Go, Rust, Python, and C/C++ language server handling.

TUI

• Added transcript search.
• Added notification queue.
• Added OSC-8 terminal hyperlinks.
• Added workflow status component.
• Fixed external editor chord handling.
• Improved no-argument slash commands.

Improvements

• Enabled more aggressive default performance/isolation behavior, including proactive pruning, context collapse, higher tool result budget, and Exa default behavior where configured.
• Reduced post-compaction token overhead by avoiding extra LLM turns, removing duplicate global memory injection, compressing todowrite description, and consolidating agent instructions.
• Improved TUI spinner pacing, toast countdown behavior, and autocomplete submit behavior.
• Removed old /goto command in favor of newer search/navigation behavior.
• Updated AI SDK versions.
• Updated OpenTUI to 0.4.1.
• Added design docs for workflows, response chaining, worktree isolation, provider support, LSP, and diagnostics.

Fixes

• Fixed provider request timeout poisoning where one header timeout could abort later requests.
• Fixed provider cache/scope behavior so native-only parameters are not sent to proxy endpoints.
• Fixed Anthropic cache scope gating and OpenAI store behavior for proxies.
• Fixed OpenAI MCP tool schema sanitization, Gemini type array handling, and unsupported schema keyword stripping.
• Fixed parallel tool call config handling.
• Fixed tool anchor memory growth with FIFO cap.
• Fixed MCP/LSP sidebar status refresh races and MCP initialization race.
• Fixed LSP duplicate spawning for external roots.
• Fixed MCP OAuth error escaping, idle server cleanup, and progress timeout resets.
• Fixed hidden session content-filter errors and double file injection.
• Fixed background subagents briefly appearing cancelled before runner start.
• Fixed workflow sandbox stability, concurrent workflow handling, and shutdown behavior.
• Fixed checkpoint global memory reading.
• Fixed Linux mock.module leakage, dream/distill tests, and memory-test hangs.
• Fixed published package startup by stripping type: module from packed package metadata.
• Fixed missing QuickJS dependencies in package metadata.
• Fixed CI branch filters and timeouts.

Developer / SDK

• Added session/message plumbing for checkpointing and response chaining.
• Regenerated SDK types for new message/error shapes.
• Added MCP client mock updates for roots support.
• Added config fields for workflows, dream/distill, provider reasoning options, and runtime feature controls.
• Added migrations for checkpoint boundary tracking.
• Split orchestration executor into foreground, background, push-to-background, and middleware layers for isolation/concurrency/guards.
• Added wire diagnostics and tool-call JSON repair support.
• Added package/prepack fixes for published binary compatibility.
• Updated dependency lockfile and SDK/provider packages.
