- 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
Remove the agent_orchestration enabled feature switch and root_delegates config; delegation edges now derive from the catalog's delegate_targets. Replace the four orchestration design/review docs with a single SUB_AGENT_DESIGN.md. Bump version to 1.13.0.
- 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
- 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
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.
