Implement workspace-scoped conversation storage with legacy migration based on host workspace metadata, active host workspace state protection, and frontend/backend conversation list scoping.
Add proactive recent-conversation prompt support with a configurable personal-space limit, frozen per conversation metadata, empty-conversation filtering, and a dedicated prompt template.
Add conversation_search and conversation_review tools with readable formatted results, workspace-only access, current-conversation exclusion, multi-keyword search, list mode, message/tool counts, read/save review modes, long-review fallback to .agents/review, and frontend detail renderers.
Move internal workspace artifacts under .agents, update upload/skills/compact/review paths, show .agents internal directories in prompt file trees, and adjust versioning ignores.
Add create_skill and a Skills tool category, move read_skill into that category, validate and archive skill folders, support host global skills and Docker/API private skills, and sync private skills into .agents/skills and prompts.
Update memory stamping with conversation/time source metadata and include frontend icon/status/display updates plus tests for workspace conversation storage and skills management.
This commit consolidates a large set of host-mode security and UX fixes across backend and frontend.
Security / execution model:
- Make permission/execution mode switches apply immediately (no deferred pending-only behavior).
- Keep runtime mode change notices durable and visible via user-message guidance path.
- Add explicit runtime message source taxonomy support and persistence:
user / presend / guidance / notify / sub_agent / background_command.
- Ensure guidance/notify insertion is batched per tool-cycle so mid-run inserts are committed together.
- Separate notify from guidance semantics for mode-change notices.
- Add direct-mode auto-fallback handling visibility on frontend.
Approval and command gating:
- Align run_command approval pre-check logic with docker behavior for approval/auto_approval modes in host execution paths.
- Keep approval retry flow and final-result semantics intact when permission errors trigger approval.
- Externalize forbidden command keyword list into JSON config:
config/forbidden_commands.json.
- Update forbidden command rejection message to user-facing wording:
用户不允许执行包含“... ”的指令.
Prompt/runtime guidance:
- Refine execution-mode runtime rule text to avoid endless workaround loops:
one safe alternative first, then request switching to direct mode when truly required.
Chat rendering / message UX:
- Prevent injected guidance/notify user-messages from incorrectly triggering assistant work header/timer chain.
- Restore correct visibility after history reload while preserving runtime-source behavior.
- Update user-header icon/label rendering by message source:
- guidance -> 引导 + navigation icon
- notify/sub_agent/background_command -> 通知 + bell icon
- user/presend -> keep normal user header.
- Add new icons: static/icons/navigation.svg, static/icons/bell.svg.
Approval panel UX:
- Convert desktop approval panel from layout-compress sidebar to overlay + blur sheet.
- Fix panel transition behavior (remove unintended vertical motion; use dedicated desktop overlay transition).
- Improve approval result display:
- decision and reason split lines,
- green/red status styling,
- multiline reason rendering,
- auto-collapse delay adjusted to 3s.
Execution mode TTL feedback:
- When direct mode auto-expires to sandbox, frontend menu state is updated from status snapshot.
- Show non-auto-dismiss warning toast to explicitly notify auto-fallback.
Misc consistency updates:
- Execution mode label text cleanup in composer.
- Runtime notice wording normalization (权限模式修改为..., 执行环境修改为...).
Build/test notes:
- Frontend rebuilt after UI changes.
- Smoke tests passed for server refactor path.
