Switch from --output-format json to stream-json --verbose to capture
per-turn data. Detail now includes:
- model name
- usage (input/output/cache tokens)
- stopReason
- turns[] as individual CAS nodes with role, content, tool calls
Also addresses PR #421 review fixes:
- sessionId guard: skip cache write when sessionId is empty/undefined
- silent catch: log resume failures with debug tag 5VKR8N3Q
- atomic write: session cache uses temp+rename for crash safety
Closes#422
Two-role debate (against/for) with up to 3 rounds per side.
Each role re-enters with session resume, making this an ideal
integration test for cross-process session continuity.
Supports early termination via concession (conceded=true in frontmatter).

- Replace resolvePathInWorkspace with simple resolvePath (no boundary check)
- Remove UWF_BUILTIN_ALLOW_SHELL env gate from run_command
- Update tests accordingly
Per review: sandbox was false security with shell=true, and path
restrictions are unnecessary for a trusted agent environment.
Move getCachedSessionId/setCachedSessionId from workflow-agent-hermes
into workflow-agent-kit so all agent adapters can share the same
session cache logic.
Add cross-process session resume to workflow-agent-claude-code:
on re-entry (isFirstVisit=false), look up the cached sessionId and
use 'claude --resume' to continue with full conversation history.
Cache file renamed from hermes-sessions.json to agent-sessions.json
to reflect its shared nature.
Refs #418
Built-in role agent that uses workflow config models directly,
with its own tool-calling run loop. No external agent dependency.
- OpenAI-compatible chat completion client with tool_calls support
- P0 toolkit: read_file, write_file, run_command
- Integrates via createAgent factory from workflow-agent-kit
- CAS detail recording for each turn
- Path sandboxing and shell opt-in (UWF_BUILTIN_ALLOW_SHELL)
Hermes ACP _restore fails for custom providers — resolve_runtime_provider
throws and base_url/api_mode are lost, causing resume to silently create a
new session with no history. Prompt then returns empty text or refusal.
Disable resume by default. Set UWF_HERMES_RESUME=1 to opt back in.
Includes investigation notes in docs/investigations/.

Two bugs fixed:
1. request_permission messages (JSON-RPC requests with both id+method) were
silently swallowed by the response handler, causing hermes to hang waiting
for permission approval. Now properly distinguish responses (id only) from
server requests (id+method).
2. uwf-hermes process never exited after completing because the hermes ACP
subprocess was still alive. Now explicitly close the ACP client after
agent completion so the subprocess terminates.

The official TS SDK's ndJsonStream hangs indefinitely on prompt()
for sessions with 20+ messages (solve-issue planner). Root cause
appears to be a stream backpressure issue in the SDK's ReadableStream
adapter.
Switch back to readline-based line parsing which reliably receives
all JSON-RPC responses. Also handle session/request_permission
inline (auto-approve, yolo mode equivalent).
Ref #398
UwfAcpClient now tracks all session/update events:
- agent_message_chunk → assistant message content
- agent_thought_chunk → assistant reasoning
- tool_call → pending tool invocation (name + rawInput)
- tool_call_update (completed/failed) → assistant tool_call + tool result
Messages are accumulated across prompts (same session) and stored
via storeHermesSessionDetail, restoring the full structured detail
(turns with tool calls, reasoning) that was lost in the initial ACP
migration.
Ref #398
The client is now created once in createHermesAgent() and shared by
runHermes and continueHermes closures. This preserves conversation
context during frontmatter retry loops — continue() sends a follow-up
prompt on the same ACP session instead of starting a new one.
Client is cleaned up via process.on('exit').
Ref #398
Replace 250-line custom ACP client with official TypeScript SDK.
Uses ClientSideConnection + ndJsonStream for stdio transport.
Same public API (connect/prompt/close), 115 lines, zero custom protocol code.
Ref #398
Remove spawnHermes, spawnHermesChat, spawnHermesResume, parseSessionId,
and buildResultFromSession. runHermes and continueHermes now use
HermesAcpClient for structured JSON-RPC communication.
Session ID comes directly from ACP protocol, eliminating #380 race
condition. Agent output collected via streaming chunks instead of
session file loading.
Phase 2 of RFC #398Fixes#380
Implements JSON-RPC client that communicates with `hermes acp` via
stdin/stdout. Replaces fragile stdout/stderr parsing with structured
protocol: initialize → session/new → session/prompt → collect chunks.
Session ID comes directly from protocol response, eliminating the
race condition in #380.
Phase 1 of RFC #398
buildOutputFormatInstruction now includes explicit language telling agents to
output ONLY schema-defined fields and to focus on their role's deliverable.
Fixes#394
Claude Code CLI adapter for the workflow engine, mirroring
workflow-agent-hermes architecture. Spawns `claude -p` with
`--output-format json` for structured output parsing.
