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
- Detach background proc context from request context so processes survive
after the 9P request returns (fixes premature SIGTERM)
- Add /proc/list file to toolsrv showing all procs with state
- Show status (running/exited (N)) in agent proc list
- Keep exited procs in tracker until explicitly dismissed
- Skip 'list' entry in ListDetachedRaw
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.
This refactors the bypass (sandbox escape) mechanism to work with remote
toolsrv deployments. Previously, bypass used a Unix socket which only
works when toolsrv runs locally. Now:
1. toolsrv exposes bypass/{pending,resolve} 9P files
- pending: blocking read returns next bypass request as JSON
- resolve: write JSON {id, approved, error} to complete request
2. olliesrv reads bypass/pending in a loop per session
- Evaluates requests through the existing bypass broker
- Policy check, rate limiting, user notification all stay in olliesrv
- Writes approval/denial back to bypass/resolve
3. When approved, toolsrv executes the command directly (no sandbox)
- Execution happens on toolsrv's host (local or remote)
- Output streams back through the normal tool call path
This enables bypass to work when toolsrv is remote:
- User sees the approval notification locally
- Command executes on the remote host outside its sandbox
Architecture:
toolsrv (remote) olliesrv (local)

The registry was keyed by agent ID but read it from a shared env map
(st.env["OLLIE_UNAME"]) that all agents overwrote — making it
effectively per-session with a race condition.
Fix: pass agent ID explicitly through the protocol at every call site.
- ctl protocol: 'load <agentID> <tool>', 'unload <agentID> <tool>'
- tools file: rdwr (Request) — write agent ID, read filtered list
- proc/new payload: 'agent=<id>' field required
- Client: SetAgentID() stores identity, included in all operations
- Empty agent ID is a hard error everywhere
- Setting OLLIE_UNAME via env ctl is blocked (prevents reintroduction)
- 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
When a tool call includes "background": true, it executes via
proc/new.bg and returns immediately with a PID in a
<system-proc-background> tag. The agent tracks active background
processes and injects their output as <system-proc-interrupt> blocks
alongside subsequent tool results.
The model sees background updates without polling. It can react to
build failures, log events, etc. naturally. Kill via PID when done.
Implementation:
- toolsrv client: CallToolBackground (uses proc/new.bg as rdwr)
- toolsrv: proc/new.bg upgraded from write-only to request-response
- agent: bgTracker collects last 20 lines of output per proc
- agent loop: injects interrupts after execToolCalls, before h.update
- system prompt: documents the background mechanism and rules
Bug: spec9p.go was double-processing payloads - parseKV unescaped
\n to newlines, then rebuilt the payload without re-escaping,
then fs9p.go's parsePayload tried to unescape again. Result:
multiline content like file contents was truncated to first line.
Fix: Pass raw payload data through to fs9p.go. Escaping/unescaping
happens once in parsePayload.
Also:
- Add proper one-pass unescape function (handles \\n correctly)
- Add TestIntegration_MultilineContent to verify fix
- Add InputSchema verification to TestIntegration_ToolExecution
- Pass session ID via --session-id flag (not env var) so tool registry is configured when olliesrv spawns toolsrv
- /tools now returns JSON array with full ToolInfo including InputSchema (fixes Bedrock validation error requiring type: object)
- Implement SpawnRemote: deploy ~/.config/ollie via tarball over SSH, set XDG_CONFIG_HOME so tools/*.meta are found on remote
- Add --no-auth flag for debugging Tauth issues
After Write(), the file offset is at the end of the written data.
For request-response files (like proc/new), we need to read the
result from offset 0, not from the current offset.
Changed CallTool() to use ReadAt(buf, 0) instead of io.ReadAll()
which uses Read() and inherits the wrong offset.
Same fix was already applied to token reading in Dial().
Added TestIntegration_ToolExecution to verify the full tool
execution path works end-to-end.
Replace HMAC-based registration with proper 9P Tauth flow:
- First client to connect sets the secret via Tauth afid write
- Server stores secret in memory, returns session token
- Subsequent clients must provide matching secret
- Secret never in env vars or disk, only transmitted over socket
Changes:
- server9p.go: Authenticate() replaces RegisterAgent/GetAgent
- client9p.go: Dial() does Tauth handshake (write secret, read token)
- spawn.go: generates secret, no longer passes via TOOLSRV_SECRET env
- auth9p.go: simplified to just GenerateSecret()
- spec9p.go: removed /register file, token validation at connection level
- cmd/toolsrv/server.go: handleAuth/handleAuthWrite/handleAuthRead
Security model:
- Session generates secret on Spawn()
- All agents share session's secret via ProcessKeeper
- Socket permissions (local) or SSH (remote) protect transport
- Secret dies with toolsrv process, new secret on respawn
Added integration tests verifying:
- First connection sets secret
- Reconnect with same secret works
- Wrong secret rejected
- ProcessKeeper reconnect/respawn behavior
- Concurrent connections
