From 3252115a678ad59c0e2d177716cb184f2b3bb269 Mon Sep 17 00:00:00 2001 From: Relayflow Lead Date: Tue, 8 Sep 2026 11:40:36 +0200 Subject: [PATCH 1/2] feat(sdk): make f.agent real, fix cross-package flow-handle identity, TS quickstart MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Three findings from actually trying to write and run a relayflow as an external user would, chased down one at a time: 1. Every externally-authored .flow.ts refused with "expected an @relayflows/surface flow handle" — a real Node dual-package-instance hazard, not specific to f.agent. flow()'s handle validation is a WeakMap keyed by module-scoped object identity in @relayflows/surface itself; an author's own project resolves its own separate copy of that package, so the CLI's internal copy's WeakMap never has the entry the author's copy wrote. The fix is NOT a new identity mechanism on the handle — surface's own test suite (flow.test.ts "refuses malformed and forged handles") already pre-empts exactly that (a Symbol.for()-tagged handle is globally guessable, so it's forgeable; tried it, reverted it, kept the WeakMap). The real fix: authored-flow-loader.ts now dynamically resolves @relayflows/surface/runtime FROM THE FLOW FILE'S OWN location (same anchor its own `import` already used), so both sides read the same WeakMap instance. That needed @relayflows/surface's exports map to also carry a `require` condition (alongside the existing ESM-only `import`) purely so `createRequire(...).resolve()` can find the file path — resolve() never executes it, so the package stays ESM-only in practice. 2. f.agent threw unsupported_verb unconditionally. The kernel already has real, tested agent-step dispatch (this morning's daemon-lifecycle workflow used it directly) — the gap was authored-flow-executor.ts never lowering f.agent into a kernel AgentStepSpec at all. Now it does, and reuses checkAuthoredFlow's existing preflight pipeline (cli/check.ts) to resolve a real CLI from the project's flows.json — the same resolution a declarative `type: agent` YAML step already gets, which an authored TS flow had never gone through. Getting this working end-to-end against a real attached worker (not just a mock) surfaced one more real bug: readCompletedStepOutput read the journal exactly once, immediately after runStart — fine for a deterministic step, which the kernel drives to completion inline, but an agent step's completion depends on an external worker actually running a real CLI process. Added a bounded poll, and made the run-outcome cross-check re-fetch fresh status only when polling was actually needed (never for the synchronous path), so the existing mock-journal unit tests keep working unmodified. 3. README's Quickstart now shows a real, verified TypeScript flow (f.run + f.done) instead of YAML, per request, plus an honest note on what's real now (f.run, f.agent) vs. still design-only (f.llm, f.human, f.dispatch, f.cloud). Verified for real throughout, not just by reading code: built a separate npm project outside this repo, installed @relayflows/surface from it, ran a flow through the actual built CLI, and added a live test (tests/live-kernel.test.ts) that runs f.agent through a real attached AgentWorker with a real spawned CLI process, not a mock. Full SDK suite (804 tests) and surface suite (7 tests) both green.

charset=UTF-8 Content-Transfer-Encoding: 8bit A review of #243 (kjgbot, plus coderabbitai/cubic/codex) found several genuine bugs in the f.agent implementation, most confirmed by actually running the code against a live daemon and worker, not just reading it. Fixed the real ones; the review's other points are addressed below too. **P1 — workspace permission annotations were silently ignored.** `workspace: "path: readonly"` was passed through as an opaque surface name with no enforcement; the reviewer proved an agent could write to a file declared readonly. No parser anywhere in this package turns that annotation into a real restriction, so `lowerAgent` now REFUSES a workspace string carrying one (`unsupported_workspace_permission`) instead of silently accepting and ignoring it. Verified live: the annotation is now rejected before any dispatch. **P1 — a fixed 30-second deadline killed legitimately long-running or genuinely parked agent runs.** Replaced the hand-rolled polling entirely with `classifyOutcome` (cli/run.ts) — the exact same wait/classification the declarative `flows run` already uses for every agent step: follows the worker's actual lease (renewing, not a wall-clock bound), and distinguishes "no worker attached, genuinely parked" from "running with a live lease" instead of guessing. Verified live: a no-worker agent step now reports PARKED (exit 3) in ~0.6s, not a protocol failure after 30s. **P1/P2 — step.completed vs. the run's terminal state race.** The kernel appends these as two separate actions (kernel/relayflowd-core/src/machine.rs: completion_actions vs. complete_run_actions), so an immediate `run.get` right after seeing `step.completed` could legitimately still read `running`. Also fixed a narrower version of the same race in my own first pass, where the run could complete between `runStart` and the very first read. `classifyOutcome` already polls to a true terminal state before this executor ever reads the journal, so the completion read is now a single safe read with no re-check needed at all — the whole class of races is gone, not patched around. **P2 — `flowPath`'s default searched one directory too high.** `checkAuthoredFlow` always does `dirname()` on the path it's given, matching `flows check`'s real file-path contract; the previous default was bare `process.cwd()` — itself a directory — so dirname() searched cwd's PARENT. Now defaults to a synthetic `join(cwd, 'flow.ts')`. Verified live: a flows.json placed only in cwd (not its parent) is now found. **P2 — `agent_cli_unresolved` reported as a protocol failure (exit 1) instead of a refusal (exit 2).** `flows check` returns exit 2 for the same failed preflight; direct-run.ts now classifies both `agent_cli_unresolved` and `unsupported_workspace_permission` the same way. Also added `agent_parked` → exit 3, matching the declarative path's parked contract exactly (same diagnostic shape, same severity). Known, documented gap not solved here (confirmed not feasible without a large redesign — an imperative TS body's f.agent calls aren't knowable without running it, unlike the static declarative compiler): if an earlier f.run already journaled real work before a later f.agent's CLI turns out unresolvable, this still reports as a clean refusal. **P2 — the published `@relayflows/surface`'s `exports` field doesn't support `require.resolve()`.** Already fixed in the base commit; this pass adds the `engines` field a reviewer correctly pointed out was missing (`>=20.19.0 || >=22.12.0`), so a CJS consumer on an older Node gets a clear, honest floor rather than a silent `ERR_REQUIRE_ESM` if it ever tries to `require()` this ESM-only package for real (the `require` condition exists only so `.resolve()` can find the file path — never to actually load it via CommonJS). **Known, deliberately not fixed here:** the review correctly found that `packages/sdk/package-lock.json` still resolves the REAL published `@relayflows/surface@2.0.6`, which lacks even the base commit's `require`-condition fix — a genuinely clean `npm ci` today would still fail `direct-input.test.ts`. My own local testing missed this because I hand-patched the already-installed `node_modules` copy rather than testing a truly clean install. This needs a real npm publish of a fixed surface (with sdk's dependency + lockfile bumped to match) — not a source-only fix — and is the natural next step after this PR merges, using this session's own working release pipeline. **Explicitly not attempted:** a live 30+ second reproduction with a worker manually renewing a step's lease via `step.heartbeat` — doing this faithfully needs extracting a `lease_id` from internal dispatch state `AgentWorker` doesn't expose (and doesn't itself renew for long-running dispatches — a separate, pre-existing property of `AgentWorker`, not something this PR touches). `classifyOutcome`'s lease-following (`waitForRunningStep`) is pre-existing, independently tested code; what's new and load-bearing here is that `lowerAgent` correctly calls it and interprets its result, which the immediate success and immediate parked live tests both directly prove. **Consciously skipped, with reason:** - Caching `checkAuthoredFlow`'s project-config/probe results across steps (coderabbitai nitpick, marked trivial) — a performance suggestion with no evidence of an actual problem; premature here. - Switching the journal read to `run.watch` instead of `journalRead` — real for the general case (100-entry response cap), but every lowered spec here is a fresh, single-step, small run, so the single post-classifyOutcome read this PR now does is not exposed to that cap in practice. - The docstring-coverage pre-merge check (33% vs. an 80% threshold) — this codebase's own convention (and this session's own instructions) is comments that carry non-obvious WHY, not docstrings for their own sake; this diff already carries unusually extensive why-comments given the subtlety involved. Verified throughout with live reproductions (real daemon, real worker, real spawned CLI processes), not just re-reading the code: workspace permission refusal, immediate-parked timing, and default-flowPath anchoring all confirmed against the actual built CLI in an isolated external project, plus two new permanent regression tests. Full SDK suite: 806 passed, 3 skipped (unchanged skip count).
