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.
Refs #391
Send a test completion request after configuration to verify the model
is reachable. If validation fails, warn the user and suggest trying a
different model or checking their settings.
Fixes#335
Replace hardcoded 5-field example with schema-driven generation.
Now shows actual enum values, types, and required markers for
each role's frontmatter schema.
Fixes#389

Replace hardcoded 5-field candidate with schema-driven extraction.
Now reads outputSchema properties and picks matching fields from
parsed frontmatter, supporting role-specific fields like plan,
approved, success.
Falls back to standard 5 fields when schema has no properties.
Fixes#388

Agent CLI outputs plain CAS hash (not JSON), engine parses plain hash.
StepOutput no longer carries sessionId — session info is already in CAS detail.
Keeps the valuable parts of #385: sessionId in AgentRunResult (process-internal),
continue support, and frontmatter retry loop.
Breaking changes:
- AgentRunResult now requires sessionId field
- AgentOptions now requires continue function
- Agent CLI outputs JSON {stepHash, sessionId} instead of plain CAS hash
- Engine parses JSON output (with legacy CAS hash fallback)
New features:
- Frontmatter validation retry: if agent output lacks valid frontmatter,
engine calls agent.continue() up to 2 times with correction message
- Session tracking: sessionId flows from agent → engine → StepOutput
- Hermes agent: session parse failure is now a hard error (no raw text fallback)
- Hermes agent: supports --resume for continue sessions
Closes#384
Agent output must contain valid YAML frontmatter matching the role schema.
If frontmatter parsing fails, the step fails immediately with a clear error
instead of falling back to an LLM extraction that can fabricate values.
The extract module remains as a public API export but is no longer used
in the agent run loop.
Breaking change: agents that relied on LLM extraction to produce valid
output will now fail. They must output proper frontmatter.
Add --count/-c flag to 'uwf thread step' for running N steps in one
invocation, stopping early if $END is reached.
- cmdThreadStep now loops up to count times, delegates to cmdThreadStepOnce
- CLI parses -c/--count, defaults to 1 (backward compatible single output)
- Validation rejects 0, negative, and non-integer counts
- 7 new tests covering CLI parsing and count validation
Fixes#373

Fallback transitions (last entry in graph node) omit the condition
field in YAML, resulting in undefined instead of null. The validator
and materializer now handle this:
- validate.ts: accept undefined as valid condition value
- workflow.ts: normalizeGraph() coerces undefined → null before CAS put
This was broken by the graph fallback pattern introduced in #370.
Register custom $first(role) and $last(role) functions in the JSONata
evaluator. These search the steps array and return the matching role's
frontmatter (output) directly, replacing verbose steps[-1].output.x
expressions with semantic $last('role').field syntax.
- workflow-moderator: register functions via expr.registerFunction()
- Updated all condition expressions in .workflows/ and examples/
- Added tests for $last, $first, and unmatched role (undefined)
Fixes#376
- Last transition in each graph node is now the fallback (no condition)
- Remove redundant positive conditions (ready, devDone, approved, passed, pushSuccess)
- notApproved → rejected (positive naming)
- Move generateCliReference() to @uncaged/workflow-util
- buildRolePrompt inlines CLI reference directly (no agent tool call)
- Fix Role terminology to use new field names
- Add maintenance comment in cli-reference.ts
- Fix test assertions
- Add legacy-packages/ and scripts/ to biome ignore
- Allow noDefaultExport in vitest.config.* and .d.ts
- Allow console in cli.ts and setup.ts (CLI user output)
- Fix unused imports in cas.ts and setup.ts
