Server:
- session/idx now outputs: session-id, session-name, paused, connected, remote, cwd
- session/{s}/agent/idx now outputs: session-id, agent-id, agent-name, parent-id, depth, state
- Add error if parent agent not found during sub-agent spawn
GUI:
- refreshSessions() reads session index, then agent/idx per session
- Auto-select first top-level agent (depth 0) instead of first in list
- SessionModel tracks agent expansion separately from session expansion
- Agents with children show expand/collapse arrows and are collapsible
- Add hasChildren role to SessionModel
Tools:
- subagent_spawn now passes parent= argument for proper depth tracking
- Remove hardcoded max_depth=5, use server default of 1
- Makefile installs shell script tools from data/tools/
KRunner:
- Update to parse new session/idx format
- Workflows are executable scripts in data/workflows/
- New 'workflows' 9P file lists available workflows
- Goal file stores text; writing triggers workflow if status allows
- goalstatus file for status read/write, goalwait for blocking
- Session ctl accepts 'run [workflow]' command
- Session now owns CWD; agents inherit via callback
- Conductor workflow: creates agent, primes with instructions, exits
- GUI workflow combo reads from workflows, not agents
- Persistence includes goal, goalstatus, workflow, and session CWD
Write to session/{s}/goal to set a session-level objective.
A conductor agent is spawned automatically in the background,
decomposes the goal, spawns sub-agents, and reports completion.
- goal file: write sets goal + starts conductor; read returns status
- goalwait file: blocks until goal status changes (BlockOnce)
- Conductor writes status=complete/blocked back to goal when done
- Session.Goal() / SetGoal() / GoalSignal() on Session struct
The step budget mechanism is gone. Agents run until they finish,
are interrupted by the user, or (for sub-agents) hit the timeout.
No replacement. The human is the kill switch.
Enforce three limits on sub-agent spawning:
- depth (default 1): sub-agents cannot spawn their own sub-agents
- parallelism (default unlimited): cap concurrent children per parent
- timeout (default 600s): sub-agents are killed after 10 minutes
Top-level agents are never constrained by timeout.
Also: refactored parseAgentNewRequest to return a struct instead of
4 positional values. Added depth/activeChildren fields to Agent.
OLLIE_SUBAGENT_DEPTH env var set on sub-agents.
Deferred: remove maxSteps (replace entirely with timeout).
- Move user-preferences.md from data/prompts/ to data/agents/.
- Remove it from prompt arrays in all agent JSON configs.
- Add userPrompts field referencing the file via $XDG_CONFIG_HOME path.
- Update justfile install target accordingly.
Sub-agents now clone the parent agent's conversation history into
their initial context. The tool script passes parent=$OLLIE_UNAME
automatically. Mechanically identical to session restore — uses
RestoreHistoryFromMessages on the parent's Messages().
Replace D-Bus fire-and-forget with blocking ollie-9p rdwr to
agent/new. The tool now:
- Blocks until the sub-agent completes
- Returns the sub-agent's reply directly
- Scope: read (multiple spawns run in parallel)
- Tier: hot
Removed: D-Bus dependency, session renaming, JIT config cleanup.
tool_load was a built-in intercept in the agent loop — the only
'tool' that didn't run in toolsrv. Removed entirely:
- Intercept in loop.go (25 lines)
- Script + .meta in data/tools/
- autoLoad references in agent configs
Loading tools is now exclusively via ctl (which already existed):
echo 'tool_load X' | ollie-9p write .../ctl
System prompt updated to show the ctl pattern.
- file_grep.meta: replace /home/user/project with /abs/path
- system_prompt.md: use $XDG_CONFIG_HOME instead of ~
- agent-copilot.md: use relative path in code block example
The sudo credential broker was never functional and added complexity
without value. This removes:
- Sudo field from bypass Request structs (broker, client, toolsrv)
- Sudo parameter from EvaluateRequest interface and implementations
- Sudo/ResetsCounter fields from MetaFile and Variant structs
- sudo: true from system_logs.meta variants
- All sudo documentation from writing-tools.md, tool-registry.md,
core.md, evolution.md, and misc.md
Bypass remains fully functional for sandbox escapes. Tools that need
elevated privileges should handle that internally or be run manually.
- KillAll(): sends SIGKILL to all running proc groups on clean shutdown
- Pdeathsig: SIGKILL ensures child procs die if toolsrv crashes
- Shell tool: use subshell + set +e for streaming without exit propagation
- Fix integration test to match new error format
This is the connection-based ownership model: toolsrv death = proc death.
The session owns the toolsrv process, so session death cascades to all procs.
- Timeout: timeout=0 means no deadline (was defaulting to 30s)
- Signal: send to process group (-pgid) not just process; SIGTERM no longer
cancels context (only SIGKILL does); cmd.Cancel sends SIGTERM with 5s WaitDelay
- Streaming: background procs stream output in real-time via procWriter;
shell tool no longer buffers all output into a bash variable
- Proc tree: olliesrv exposes proc/{id}/out, proc/{id}/ctl, proc/{id}/status
as proper 9P directory (was broken flat file)
- Connection: proc handlers dial fresh toolsrv conn per request via
Session.DialToolServer() to avoid deadlocking the agent's blocked conn
- Stat format: key=value (exited=true, exit_code=N, id=N) matching client parser
- GC: procs auto-removed 10min after LastRead (exited procs only)
- Rename: PID -> ID throughout (synthetic, not OS PID)
- Ctl commands: term (SIGTERM), kill (SIGKILL), signal <n>, dismiss
- System prompt: correct ollie-9p commands for proc management
