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.
Add Sub-Agents section explaining agent/new with prompt= key.
Include examples for single and parallel sub-agent spawning.
Update 9P namespace table to show agent/new as rdwr.
Writing to session/{s}/agent/new with a prompt= key now blocks
until the agent completes its task, then returns the reply and
destroys the transient agent. Without prompt=, behaves as before
(creates agent, returns ID).
Also:
- Move ParsePayload/UnescapeValue to shared ollie/toolsrv package
- Remove duplicate implementations from cmd/toolsrv/internal/server
- Add session.CreateAgentWithParams for direct AgentParams usage
- Eliminate flattenParams/unescapeValue redundancy in fs package
Read, Write, and Rdwr are the three atomic 9P operations:
- Read: non-blocking read
- Write: non-blocking write (fire-and-forget)
- Rdwr: atomic write-then-read (blocking, produces result)
BlockOnce and Stream are special cases of Read.
Rdwr is its own primitive — not a variant of either.
All foreground tool calls now acquire a lock based on the tool's
declared scope and file path before execution:
- scope "read": no lock (reads never conflict)
- scope "write": exclusive lock on the file path
- scope "global": exclusive global lock (serializes with everything)
This ensures writes to the same path serialize regardless of which
agent initiated the call, enabling safe parallel sub-agents within
a session without explicit coordination.
Cross-session serialization (shared toolsrv per host) is left as
future work.
The persist path created agents with &Runtime{} (nil Preamble).
If a prompt arrived before resume rebuilt the runtime, Preamble.Set
panicked. Initialize with an empty Preamble.
ListProcs now does rdwr to toolsrv proc/list with the agent ID.
Returns pre-formatted text. Ctl proc handler uses it directly.
Removed all ListDetachedRaw map-parsing logic.
- Remove /tools from olliesrv root (toolsrv owns all tool state)
- Add /all file to toolsrv namespace (lists all available tools on disk)
- Add ListAllTools() to toolsrv client library
- Add tools_all ctl command to agent (reads from toolsrv/all)
- Update system prompt with tools_all usage
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.
On context cancellation, close the connection first to unblock
ReadFcall. Then wait for in-flight handlers, drain the response
channel, and wait for the writer to finish. No writes hit a
closed socket.
