Cloud Agent - Add Slash Command Support

[eshurakov]

Summary

Add end-to-end slash command support across the cloud agent stack by introducing discriminated send payloads (prompt vs command).

• Execution layer: Introduce ExecutionPayload union (PromptExecutionPayload | CommandExecutionPayload) and dispatchToWrapper() to route prompts vs commands to the wrapper client.
• Command catalog: Add commands.available event to cache and broadcast kilo slash commands to connecting clients. Remove hardcoded default-command-sets in favor of runtime catalog from kilo.
• Web SDK & UI: Update transport, session manager, normalizer, and chat components to handle command payloads and available commands.
• Mobile: Update session manager and detail content for slash command support.
• Wrapper: Open ingest connection for slash commands (mirroring prompt flow) and push command catalog on connect/reconnect.

Verification

Reviewer Notes

• Both prompt and command payloads ride the same sendMessageV2 tRPC method; the orchestrator branches only at the final wrapper call.
• model validation is skipped for command payloads since kilo applies the command's own agent/model override.
• The DO caches the command catalog separately from session metadata to avoid polluting MetadataSchema.

All Fixed Issues (across all review rounds)

File	Issue
services/cloud-agent-next/wrapper/src/server.ts	✅ WARNING — state.setActive(false) now called on both success and error paths
services/cloud-agent-next/src/session/ingest-handlers/commands-available.ts	✅ as cast replaced with commandsPayloadSchema.safeParse(data)
services/cloud-agent-next/src/websocket/stream.ts	✅ eventId: 0 sentinel comment added
apps/web/src/components/cloud-agent-next/CloudAgentProvider.tsx	✅ Inline WorkerPayload replaced with imported SendMessagePayload
apps/web/src/components/cloud-agent-next/NewSessionPanel.tsx	✅ DEFAULT_SLASH_COMMANDS unused import removed
apps/mobile/src/components/agents/mobile-session-manager.ts	✅ Inline WorkerPayload type removed; now uses SendMessagePayload from apps/web/src/lib/cloud-agent-next/types.ts

Other Observations

Circular dependency resolved: SlashCommandInfo type was moved from slash-commands.ts into default-slash-commands.generated.ts and re-exported, eliminating the import cycle between the two files.

DB migration squash: Branch-local migrations were squashed per AGENTS.md guidelines. The agent_environment_profile_kilo_commands table creation is in 0117_wise_taskmaster.sql. Content is clean — CREATE TABLE on a new table, proper ON DELETE cascade FK, unique constraint on (profile_id, name), profile_id index. No blocking DDL.

GDPR / soft-delete: The new table cascades off agent_environment_profiles, which is already deleted in softDeleteUser. No GDPR update needed.

SendMessagePayload consolidation: Shared type in apps/web/src/lib/cloud-agent-next/types.ts, re-exported from cloud-agent-client.ts, used in mobile-session-manager.ts.

messageId thread-through: Correctly plumbed from dispatchToWrapper through WrapperCommandOptions, kilo-api.ts, and server.ts.

listCommands skill filter: kilo-api.ts filters out source === "skill" from the live catalog, matching TUI behavior.

@cloud-agent-shared path alias: The tsconfig.json alias points apps/web directly at services/cloud-agent-next/src/shared/slash-commands.ts, creating a cross-package import without a formal boundary. Works today but may need attention if packages are split or build system changes.

Files Reviewed (incremental, 3 files)

• services/cloud-agent-next/src/session-service.test.ts — test model fixture updated from claude-sonnet-4-20250514 to kilo/claude-sonnet-4-20250514 to match normalizeKilocodeModel behavior; no issues
• services/cloud-agent-next/src/shared/default-slash-commands.generated.ts — SlashCommandInfo type moved here from slash-commands.ts to break circular dependency; no issues
• services/cloud-agent-next/src/shared/slash-commands.ts — now imports and re-exports SlashCommandInfo from generated file; no issues
