Summary

Slash skills are now enabled by default and support multi-skill orchestration — referencing 2+ /skill-name in a single message auto-loads their contents and injects an orchestration plan. /skip-permissions adds a runtime toggle for unattended runs — forced-ask operations (destructive bash, etc.) auto-reject after 60s with actionable feedback, while other non-deny permissions auto-allow.

Agent mode is now locked after first message: Build and Plan can still switch between each other, but entering Compose isolates the session to that mode. Many models tend to ignore tools that appear mid-conversation, so keeping the skill/tool set fixed from session start significantly improves tool-call reliability.

Custom provider compatibility: /modalities command lets users configure multimodal support (image, audio, video, pdf) for custom models directly in the TUI without manual config editing; system prompt is now sent as a single {role:'system'} message instead of two, fixing vLLM and other backends that expect exactly one system message; Moonshot/Kimi tool calling no longer 400s on discriminated-union schemas; oversized images are now compressed and area-averaged downscaled before sending, preventing permanent 400 failures.

Other highlights: orchestrator mode improvements (liveness tracking, fan-in aggregation, stall watchdog, structured notification cards); workflow meta.permissions manifest for up-front permission declaration; /rebuild command to manually rebuild context from checkpoint; file hooks hot-reload from any external editor without restart; builtin skills gated by CLI availability; broken custom tools no longer crash the session.

Slash skills 默认开启，支持多技能编排——一条消息里引用多个 /skill-name 会自动加载对应技能内容并生成编排计划。新增 /skip-permissions 命令，适合无人值守跑任务——危险操作 60s 无响应自动拒绝，其余非 deny 权限自动放行。

模式锁定：发送第一条消息后 agent 模式不可切换（Build/Plan 之间仍可互切，但 Compose 进入后隔离）。很多模型不喜欢中途出现的新工具、倾向于不调用动态插入的 skill，锁定模式让 skill/tool 集合从会话开始就固定，显著提升工具调用成功率。

Custom Provider 兼容性改进：新增 /modalities 命令，可以直接在 TUI 里为自定义模型设置多模态支持列表（图片、音频、视频、PDF），不用手动改配置文件；system prompt 合并为单条消息发送，修复 vLLM 等后端因双 system message 导致的指令重复问题；Moonshot/Kimi tool calling 不再因 discriminated-union schema 报 400；超大图片发送前自动压缩和面积均值缩放，不再因尺寸超限导致 400 永久卡死。

其他：orchestrator 模式改进（存活状态跟踪、fan-in 聚合、卡顿监控、结构化通知卡片）；workflow 支持 meta.permissions 清单用于前置权限声明；新增 /rebuild 命令手动从 checkpoint 重建上下文；文件 hooks 支持外部编辑器热重载；内置 skill 按 CLI 可用性自动门控；自定义 tool 文件有语法错误不再导致整个 session 崩溃。

Bug Fixes

  • session: system prompt collapsed from two {role:'system'} messages to one — fixes vLLM and other self-deployed backends that only accept a single system message; memory instructions scoped to checkpoint owners only by @wqymi in #1636
  • provider: fix Moonshot/Kimi 400 errors on tool calls — strip parent type from discriminated-union tool schemas by @mvalentsev in #1665
