- AgentCatalog now records per-definition load errors (bad YAML, unknown
provider/profile/model/tool/skill, or explicit delegate edge to an absent
target) and excludes only the failing definition, never failing gateway
startup or reload; config- and directory-trust-level errors stay fatal
- Explicit delegation to an absent target cascades to deactivate the
delegating agent; `*` and implicit general-purpose delegation do not
- GET /api/agents lists broken definitions with parse/load errors so they
can be fixed and re-enabled from the WebUI instead of disappearing
- WebUI shows an error banner on broken definitions, hides the enable switch,
pre-fills the editor via lenient parsing, and re-enables on save
- Bump version to 1.16.0
- 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
- rename settings tab and editor labels (子代理定义 → 子代理, 可继续委托给 → 递归委托)
- show available sub-agents as selectable tags when delegation is a list
- fix edit button text wrapping next to the enable switch
- add hot reload button + phase status polling to the sub-agent pane
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}.
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
- RunQuota now enforced: background admission acquires the run permit
(global→session) and the runner holds it until terminal commit;
foreground never takes run permits so nested limit=1 cannot deadlock
- RuntimeAdmission activity guard held by background runners for the
whole run; admission checked before any durable write
- signal_contract_json/signal_delivery persisted at run admission so
definition-level steer delivery actually takes effect (was silently
falling back to queue)
- terminal completion payload carries the run's emitted signal IDs
(design §12.3) so the main Agent can recognise duplicates
- ROOT caller_scope_id is the literal "ROOT" (design §9.6)
- legacy general delegation returns a deprecation/migration hint
Cleanup:
- remove unused AgentCaller enum and run_parallel wrapper
- remove unreachable http_get_only prompt machinery (http_request is
RootOnly and never enters sub-agent registries)
- drop never-read EmittedSignal fields; derive WakeupSource from
TurnInputSource instead of duplicating match arms
- replace the /stop oneshot compatibility bridge with a plain turn_busy
flag; the worker's forced-cancel path now selects on the cancellation
token (implementation doc §11.1)
Version 1.8.0
- 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
- Replace static Space Grotesk weights with a variable font (300-700) and
bump the type scale across all tiers for a clearer weight hierarchy
- Add dot-grid texture, ambient glow, layered shadows with machined edge
highlights, and entrance/hover/press micro-interactions (reduced-motion aware)
- Refine sidebar and session list: sliding amber active indicator, search
focus ring, SESSIONS label header, living status dot, backdrop-blurred bars
- Replace inconsistent glyph icons with a unified Lucide-style SVG icon set;
rename 工具&Skills to 工具 and enlarge nav font
