Replace the dual task/monitor model, NO_REPLY string protocol, and Agent
self-delivery with a single Scheduled Run path: claim-time JobRun snapshots,
isolated Root/named Agent execution, exactly-once complete_scheduled_run
termination, and Scheduler-owned policy delivery through a persistent outbox.
- SQLite v11: drop job_kind/model/delete_after_run, add job_runs with
status/outcome joint constraints and delivery lease columns; one-shot
BEGIN IMMEDIATE migration with atomic rollback.
- Non-blocking JoinSet event loop with bounded run/delivery concurrency;
terminal commit before any channel I/O; recover unfinished runs as unknown.
- ExecutionOrigin::Scheduled propagates to descendants, completion sink is
top-level only, background delegation downgrades to foreground.
- Typed delivery receipts, fixed target_session_id, idempotent
scheduled:<job_run_id> history insert.
- New cron_runs read-only tool; cron_add/update drop kind/model; WebUI and
Health consume the same JobRun projection.
- Bump version to 1.22.0.
Restructure the WebUI around sub-agent activity: move definition management into Settings, turn the agents page into a live activity monitor with a read-only detail view, and slim the tasks page to scheduled jobs only. Persist incrementally streamed per-run transcripts in a new agent_run_messages table (schema v9, version-gated drops preserve v8 run history) and expose them via GET /api/agent-runs/{id}.
- drop agent_run_groups table and group_id/scope_kind/scope_id columns (schema v8)
- remove group_id from AgentExecutionContext and recovery group counters
- flatten TasksPage background tab into a per-run list
- add WebUI Agents page with definition CRUD and inline provider/model
- bump version to 1.11.0
- bash is now Delegatable so named Agents may run shell commands
- remove the legacy anonymous 'general' path entirely: SubAgentManager
run_background/run_foreground_batch/run_inline/run_foreground,
filter_tools/get_skills_prompt, TaskNotification direct delivery,
DelegateContext task-local, background_permits/admission, and the
delegate tool's check_task/cancel_task/list_tasks actions (agent_task
replaces them); /stop and todo migrate off the task-local bridge
- stop writing the legacy background_tasks table (read-only transition);
/api/tasks union still renders historical records
- ship a built-in general-purpose Agent definition (resources/agents)
released to ~/.picobot/agents on first run like built-in skills, with
bash/read-only/search/web/calculator/sleep tools; root_delegates now
defaults to it so orchestration works out of the box
- update AGENTS/README/architecture/config/db-schema docs accordingly
- AgentCatalog/definitions with strict Markdown frontmatter, delegation graph,
fail-closed tool scoping, and signal contracts
- structured cancellation (AgentError::Cancelled/TimedOut) across provider
streams, tool batches, and sleep; /stop drives the same terminal state
- schema v6 run/group/inbox persistence with execution-ID conditional
transitions and completion-slot reservations
- ExecutionGate separating run quota from provider/tool step permits
- background completion inbox with hidden-trigger continuation turns,
fairness scheduling, lease release, dead-lettering, and activation recovery
- typed TurnMailbox with two-phase steer admission and atomic consumption at
turn commit; /stop releases admitted steer events back to pending
- emit_signal tool with contract-enforced rate/dedupe/severity/size limits
- WS run/event projection (GetAgentRuns, AgentRunUpdated, AgentEventUpdated),
/api/agent-runs* management endpoints, /api/tasks union, WebUI run tree
and signal cards
- ChannelContext.durable_private persisted for continuation delivery reuse
Version 1.7.0
Resolve strict Clippy findings across all targets, preserve public API compatibility with scoped lint exceptions, and fix sourced messages retaining media references. Replace meval and its future-incompatible nom dependency with a bounded internal expression parser and regression tests.
Add versioned SQLite migrations, enforced runtime pragmas, and transactional message constraints. Claim scheduled jobs with durable leases, execute them concurrently within bounds, and commit completion atomically. Supervise background tasks and clean up WebSocket clients and writer tasks during ordered shutdown.
- Removed InputHandler and related input event handling code.
- Updated GatewayState to handle new session commands for dialogs.
- Introduced UnifiedSessionId for managing session identifiers across channels and chats.
- Refactored Session and SessionManager to manage dialogs instead of sessions.
- Added methods for creating, listing, switching, renaming, archiving, and deleting dialogs.
- Updated storage functions to accommodate dialog IDs in persistent session management.
- Enhanced tests to cover new dialog functionalities and ensure stability.
- Added SessionSummary struct for session metadata.
- Updated ws_handler to create and manage CLI sessions more robustly.
- Implemented session creation, loading, renaming, archiving, and deletion via WebSocket messages.
- Introduced SessionStore for persistent session storage using SQLite.
- Enhanced error handling and logging for session operations.
- Updated protocol definitions for new session-related WebSocket messages.
- Refactored tests to cover new session functionalities and ensure proper serialization.
