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.
- Store default SQLite database at <config_dir>/data/picobot.db instead of
the workspace, keeping session data independent of the workspace; the
reload equivalence check and docs follow the new default
- Add per-skill enable/disable persisted in <config_dir>/skills_state.json;
skills default to enabled, disabled skills are excluded from prompts,
listings, and get_skill at load time
- Add mcp.servers[].enabled (default true); disabled servers are skipped
at activation and by health checks
- WebUI Tools page: switches for Skills and MCP servers, plus a concrete
MCP tool list with connection status and errors
- Add PUT /api/skills/{name} API and expose enabled/tool details in the
skills/status APIs
- Bump version to 1.15.0
- 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
