Named multi-agent / per-agent model support in the TS authoring surface

[khaliqgant]

Named TypeScript agents now select their own CLI and model, with independent per-step overrides. For example, f.agent('reviewer', { task, model: 'model-b' }) keeps the reviewer's CLI while selecting the overridden model. Unmatched names retain the project-default behavior used by existing callers.

The flow header is captured once as inert descriptor data, validated, and frozen. Every declared agent is checked before the body runs, including unused declarations. Declaration preflight and executable-step preflight share agent policy; successful CLI/model probes are reused within one execution. Refusals preserve cli_missing, model_unknown, and model_unavailable through the direct CLI.

Agent lowering and journal output decoding are extracted from the executor, and named-agent tests have dedicated suites. The rebase preserves main's current README and local-agent support. The existing 2.0.9 package/version alignment is retained; this PR does not publish packages.

Verification commands and captured outputs: docs/evidence/pr245. This includes the full SDK and Rust workspace runs, the unchanged packed-consumer gate using Bun 1.4.0, and the named-selection negative control followed by byte-for-byte restoration and a passing rerun. The live test uses a real daemon and SDK worker with distinct local wrapper executables; it asserts the actual dispatched CLI/model pair and readiness-probe counts.

The local three-lens relayflow passed at b88244113be0ca330b01871fdd0588ac483e5f59; captured command, output, and independent verdicts are attached. The Linux artifact, packed-consumer, and wrapper-guard checks passed on that head. The separate hosted review is still running; its previous attempt could not produce a structure transcript because OpenCode reached its monthly spending limit, documented in the follow-up. Gate files and spending limits are unchanged. No merge performed; Chief owns the merge gate.

Note

Medium Risk
Changes agent CLI/model resolution, preflight gates, and how run/check refusals are surfaced—core execution path behavior, though aligned with existing declarative semantics.

Overview
TypeScript flows can declare named agents in the header (agents: { reviewer: { cli, model } }) and f.agent(name, options) resolves against that map, with step-level cli/model overrides taking precedence. Names that do not match a declaration keep today’s project-default behavior, so existing step ids used only for readability are unchanged.

Preflight is unified with the declarative compiler: a per-execution createAuthoredFlowChecker validates every header agent before the flow body runs (including unused entries), reuses successful CLI/model probes within one run, and lowers matched steps to the same FlowSpec.agents / kernel path as YAML. direct-run and AuthoredFlowExecutionError now carry the specific refusal kind (cli_missing, model_unknown, etc.) instead of collapsing to invalid_spec.

Docs and verification: docs/SURFACE.md states both dialects share one contract; large docs/evidence/pr245 and remediation logs capture test runs. Minor lockfile dependency bumps are included.

📝 Walkthrough

Walkthrough

The PR adds named-agent declarations to the TypeScript flow surface. It validates and freezes declarations, preflights all declared agents, preserves refusal kinds, supports step-level overrides, adds execution coverage, updates documentation, and publishes version 2.0.9.

Changes

Named agent support

Layer / File(s)	Summary
Define and validate named agents packages/surface/src/context.ts, packages/surface/src/flow.ts, packages/surface/src/index.ts, packages/surface/tests/flow.test.ts	The public surface adds named-agent declarations, FlowHeader.agents, and step-level CLI and model overrides. Declarations are validated, copied, frozen, and exported.
Preflight and lower named agents packages/sdk/src/authored-flow-agents.ts, packages/sdk/src/authored-flow-executor.ts, packages/sdk/src/authored-flow-error.ts	The executor preflights every declared agent before the flow body runs. Named selections and step-level overrides are lowered into the authored specification.
Preserve refusal kinds at the CLI packages/sdk/src/cli/direct-run.ts	Direct execution reports specific refusal kinds such as model_unknown and cli_missing.
Validate agent execution behavior packages/sdk/tests/authored-flow.test.ts, packages/sdk/tests/live-kernel.test.ts, packages/sdk/tests/direct-input.test.ts, packages/sdk/tests/fixtures/named-agent-bad-model/*	Tests cover validation, preflight timing, CLI and model resolution, override precedence, multiple agents, and CLI refusal output.
Document and publish the surface README.md, docs/SURFACE.md, packages/*/package.json	Documentation describes the named-agent and workflow surfaces. Package versions and pins move from 2.0.8 to 2.0.9.

Priority: ➖ Normal — Schedule the named-agent support because it expands the TypeScript authoring surface and requires coordinated publication of the surface and SDK packages.

Estimated code review effort: 4 (Complex) | ~45 minutes

ALIGNED WITH FINDINGS at 4c5234297866ef4f1146c504eed92765503c8325.

Named agents and per-step CLI/model overrides are lawful extensions of the open TypeScript surface, compiled to the existing agent verb. They do not widen the closed kernel vocabulary. The remaining findings are two reproduced authoring-validation defects and a live test that does not prove the distinction it names. This is not an approval.

Findings

1. P1 — Preflight declared header agents before executing the body. packages/sdk/src/authored-flow-executor.ts:141 now accepts the agents header, but its only call into named-agent preflight is inside lowerAgent (packages/sdk/src/authored-flow-executor.ts:199, packages/sdk/src/authored-flow-executor.ts:222). A flow with a statically declared, unregistered model can therefore execute f.run and finish successfully if no f.agent is reached; if an agent is reached later, the refusal occurs after the command's effect. My live reproducer writes a disposable marker in both cases: UNUSED_INVALID_HEADER reports success with marker: "effect"; LATE_HEADER_REFUSAL reports model_unknown after marker: "already-executed". This violates RFC covenant 2 (docs/RFC-0001-everything-is-a-relayflow.md:34) and SURFACE §2, which requires every named model—including unused/shadowed declarations—to be checked before commands (docs/SURFACE.md:164), and explicitly says TS preflights its declared agents (docs/SURFACE.md:204). The new status text claiming the same contract in both dialects (docs/SURFACE.md:191) is consequently too broad. This is header data already available before the body starts, not a demand to statically predict arbitrary TS control flow. Run that declared-data validation before allowing body effects.

2. P2 — Reject accessors on the agent map before enumerating it. packages/surface/src/flow.ts:209 uses Object.entries(value.agents) without validating the map's property descriptors. packages/surface/src/flow.ts:157 then enumerates it again while freezing. A getter can return a legal {cli, model} declaration for validation and a different, invalid declaration for storage. The executed ACCESSOR case is accepted, invokes the getter twice, and retains {cli: 42, model: "model-b", permissions: "write-all"} in getFlowDefinition(handle).header.agents. This violates the closed declaration contract in SURFACE §2 law 6 (docs/SURFACE.md:79) and its inert-data/snapshot rule in §6 (docs/SURFACE.md:399), consistent with decision 9 (docs/RFC-0001-everything-is-a-relayflow.md:211). Validate descriptors without invoking getters, then validate/freeze the same data snapshot. This is an authored-handle validation escape; I am not claiming the extra permission field bypasses the downstream kernel compiler or grants permissions to a worker.

3. P2 — Make the “two distinct named agents” test distinguish the selected agent and model. packages/sdk/tests/live-kernel.test.ts:448 gives both names the exact same CLI and model; its wrapper ignores request.model and returns only the supplied task (packages/sdk/tests/live-kernel.test.ts:414). Consequently the assertions at packages/sdk/tests/live-kernel.test.ts:466 pass even when every name selects the first declaration. I executed that precise negative control by temporarily replacing agent: name with agent: Object.keys(namedAgents!)[0]: the named test still passed. I restored the source byte-for-byte and reran the same test; it passed again. Commands, output, and identical restoration hashes are below. The test proves two instruction round trips through a declared CLI, not distinct named-agent selection or per-agent model propagation. This misses the behavior specified by SURFACE §2 law 6 (docs/SURFACE.md:84) and the deterministic-test requirement in AGENTS.md rule 5 / RFC §2 rule 6 (AGENTS.md:19, docs/RFC-0001-everything-is-a-relayflow.md:66). Use distinguishable CLI fixtures and model values and assert their actual worker requests/outputs. My separate live fixture does so and confirms that the current implementation itself selects both correctly and honors overrides.

Requested spec answers

1. Decision 13 — aligned; no vocabulary widening. packages/sdk/src/step-fields.ts:16 remains exactly AGENT_DECLARATION_FIELDS = ['cli', 'model']; packages/sdk/src/step-fields.ts:34 retains the closed agent fields instruction, agent, cli, model, surfaces, recoveryMode, permissions, output. Neither descriptor nor kernel/ changes in this PR. New TS fields are copied into existing authoring fields (packages/sdk/src/authored-flow-executor.ts:204) and lower to type: 'agent' (packages/sdk/src/compile.ts:543), as required by RFC decision 13 (docs/RFC-0001-everything-is-a-relayflow.md:215) and SURFACE §2 law 6 (docs/SURFACE.md:79). The CLOSED_FIELDS, DISTINCT_ACTUAL, and COMPILED_BOUNDARY outputs demonstrate this with two actual CLI fixtures and two different declared models. The surface's new type does not create a new kernel verb.
2. Decision 9 — compiled boundary remains aligned. The existing check/compile path still produces the kernel spec before journal.runStart (packages/sdk/src/authored-flow-executor.ts:222, packages/sdk/src/authored-flow-executor.ts:238). The captured submissions contain resolved cli/model values and existing step types, with neither top-level agents nor per-step named agent selectors left at the boundary (packages/sdk/src/compile.ts:543). That matches decision 9 (docs/RFC-0001-everything-is-a-relayflow.md:211). Finding 2 concerns the earlier authored-handle validation, not a new protocol or closure crossing into the kernel.
3. Decision 6 — no new gate-edit or permission-widening mechanism found. Normal named declarations reject permissions, tools, gate, and identity extras (packages/surface/src/flow.ts:212); all four refusals were executed below. The executor still refuses other headers (packages/sdk/src/authored-flow-executor.ts:141) and lowers only the supported named CLI/model data. No gate file changes appear in the diff. This respects the scope of decision 6 (docs/RFC-0001-everything-is-a-relayflow.md:208); finding 2 still needs fixing and is not evidence of an actual gate-edit exploit. No gate was used as a test fixture.
4. Decision 11 — kernel completion discipline is retained. Named calls use the existing classification and journal-result reader (packages/sdk/src/authored-flow-executor.ts:249, packages/sdk/src/authored-flow-executor.ts:478), without adding quality judgments. The successful distinct-agent flow records success for all three agent calls and terminal completion. A nonzero-exit named worker journals step.completed: worker_error and run.completed: step_failed; the executor rejects instead of reaching f.done('success'). This matches the kernel/evidence split in decision 11 (docs/RFC-0001-everything-is-a-relayflow.md:213). A pre-existing limitation remains visible: the SDK exception's completionReason is null for this outer step_failed outcome, while the journal has both reasons; the filtering logic is unchanged from the PR base, so I am not attributing that defect to named-agent support.
5. Documentation — local quickstart behavior reproduced; declared parity needs finding 1 fixed. I extracted the exact explain-env.flow.ts body from README.md:49, installed a separate copy of the PR surface, used its documented {"cli":"claude"}, and ran the built CLI without a worker. It executed the deterministic step and exited 3, printing PARKED [run_parked] agent_parked, matching README.md:78 and SURFACE §5 (docs/SURFACE.md:367). The cloud deployment/admission and recurring-schedule claims at README.md:84 were not exercised; a local result is not evidence of hosted behavior. No cloud run was submitted.

Executed checks and scope

SDK build: passes with the PR's packed surface. Full SDK suite: 812 passed, 3 skipped. Explicit targeted run of authored-flow.test.ts, live-kernel.test.ts, plus the latest commit's direct-input.test.ts: 64 passed. Surface suite: 8 passed. Literal output below is the authority for these counts. The three full-suite skips are the opt-in real-cli-adapters.test.ts cases; the live analyzer test ran.

The required build against a clean lockfile-installed surface initially fails with missing agents/cli/model types; that output is included rather than hidden. The PR explicitly states that source changes need a version bump/publish, so I tested the actual packed PR surface instead of treating the old published package as the new implementation. The green build/suite claims are conditional on that setup, not a claim that the unmodified published dependency already contains the new API.

The PR advanced during review; this comment reviews the head named above, including the latest refusal-kind propagation change. It now preserves model_unknown rather than reducing it to a generic invalid-spec kind; the updated direct-input test is included in the targeted execution. Findings 1–3 remain reproducible at this head. Source was restored after the negative control; no tracked edit, gate edit, approval, merge, or push remains. This negative control is a deliberately broken selector that survived a test, not a claim of “mutation-verified” coverage.

Review-only scripts live in .review-evidence/pr245/ in this worktree. Their full source is embedded here so the review does not depend on access to a private artifact. The probes use disposable files, a local daemon built from this checkout, real spawned fixture CLIs, and the real journal client/worker. The quickstart fixture uses the installed Claude authentication probe, with no model invocation because it has no attached worker.

kjgbot findings

1. P1 (unused-agent model unchecked before body effects) — executeAuthoredFlow now runs real preflight against every declared header agent (via a placeholder no-op deterministic step) before the body runs, so an unregistered model on a never-selected agent refuses before any f.run effect happens. Verified with a marker-file test mirroring your reproducer (existsSync(marker) is false).
2. P2 (accessor on the agents map bypasses validation) — both the validation and freezing passes now read entries through Object.getOwnPropertyDescriptor (rejecting non-data properties outright) instead of Object.entries, so a getter is never invoked at all. Added a test using your exact reproduction pattern, asserting reads === 0.
3. P2 (test doesn't distinguish selection) — rewrote the live test with two distinct stub CLIs/models that each echo their own identity, plus a step-level override case. Verified with the same negative control you used (agent: Object.keys(namedAgents!)[0]): it now fails under that mutation and passes on restored source.

cubic findings — trimmed-value requirement for declaration cli/model/agent names, the README EXIT:0 substring-match + unverified-success bug (same one coderabbitai flagged independently), and the namedAgentFixture temp-dir leak — all fixed.

Full SDK suite: 812 passed (1 unrelated pre-existing flaky timing test, passes in isolation), 3 skipped. Surface suite: 10 passed.

Addressed the review-swarm findings (three lenses: maintainability, history, structure) in 456c9e5:

history (H1, the substantive one) — the first "check declared agents upfront" fix only checked model-registry membership (via a no-op deterministic placeholder step, which preflight never CLI-resolves). A declaration with a registered model but a missing/unauthenticated CLI still let an earlier f.run effect happen before the eventual refusal, once the body reached that agent — reproduced exactly as your reproducer showed. Fixed: preflightDeclaredAgents (new authored-flow-agents.ts) now builds a real type: 'agent' step per declared name, so CLI resolution and probing run for every declared agent up front, same as the model check already did. Added a regression test proving no body effect precedes this refusal even when the agent is later selected, plus a live test proving a valid-but-unused declaration doesn't block the flow.

structure — extracted preflightDeclaredAgents/findRefusalDiagnostic into their own module (authored-flow-agents.ts), both addressing "extract a pure helper" and reducing authored-flow-executor.ts. Worth noting: that file was already 555 lines (over the 500-line threshold) before this PR touched it at all — this PR's net contribution is now +36 lines, and a full split of the pre-existing size is a separate, larger refactor out of scope here.

maintainability — added the explicit getter-safety contract comment in flow.ts (F1), a defensive namedAgents[name] !== undefined guard (F2), rewrote lowerAgent's comment to state the positive contract first (F5), and clarified workspace: "src"'s semantics in the README (F9). F3 is now moot given the structure fix; F4's stub-label concern is already caught by the existing per-binary label echo (a misdispatch would surface as a mismatched label, which the test already asserts on) — no further change there. F8 (changelog) and F11 (fixture path style) are left as-is; both are explicitly non-blocking in the report and out of scope for this PR.

Full SDK suite: 813 passed (1 unrelated pre-existing flaky daemon-artifact-timing test, passes in isolation), 3 skipped. Surface suite: 10 passed.

Addressed in edf8cb2 (second swarm rerun — first rerun hit a transient 503 from an overloaded relaycast database, unrelated to code):

history (H1, real regression) — the README's quickstart replaced the old f.run-only example (#243) with f.run + f.agent, which parks without a worker attached. A fresh local user with no worker configured couldn't complete the documented quickstart at all — only reach a parked diagnostic — regressing the "under ten minutes, working flow" bar, with the cloud alternative account-gated. Restored hello.flow.ts (verified to complete in well under a minute) as the first quickstart step; the f.agent example now follows in its own "Add a coding agent to a flow" section, keeping the same honest parking/worker explanation.

maintainability — added the F1 synchronization-invariant comment (both validation call sites resolve through the same checkAuthoredFlow by construction; documented why that must stay true). F4 (malformed flows.json models array) is already covered — readProjectConfig (cli/check.ts:171-193) validates this and tests/cli.test.ts:350 exercises config_invalid for it; both preflightDeclaredAgents and lowerAgent go through that same function, so no new test was needed. F3 (documenting unused-agent preflight cost) — decided not to add to the README specifically, since the README doesn't currently demonstrate the header-level agents: map at all; the code-level comments already explain the rationale. T1 (model-only override without a cli override) — real but low-severity per the report's own table; not added this round.

structure — still flags the executor's file size and the "fabricated step" pattern, even after the earlier extraction into authored-flow-agents.ts. Worth being explicit about the tradeoff: the executor was already 555 lines (over the 500-line threshold) before this PR touched it at all, and the synthetic-step pattern is what makes CLI probing for declared-but-unused agents possible without duplicating checkAuthoredFlow's resolution logic a third time. A full three-way split (header validation / FlowSpec lowering / journal lifecycle) is a legitimate follow-up, but it's a larger, higher-risk refactor of code this PR didn't otherwise touch, and out of proportion to "add named-agent support." Not doing that split in this PR — flagging it as a real, separate piece of debt instead of silently ignoring it.

Full SDK suite green (61/61 on the two most relevant files, full suite passing as of the last full run). Verified the restored hello.flow.ts actually completes locally (exit 0, completionReason: success) before committing.

maintainability

Captured final verdict

Blockers

None.

Concerns

1. packages/sdk/src/preflight-cli.ts:208-218, preflightAgentDeclarations. This function puts the agent name into the stepId field of CliResolution (resolutions.push({ stepId: agent, ... })). probeResolvedCli then writes messages such as Step "reviewer" declares CLI "…" for a header declaration, which is not a step at all. The test at authored-named-agents.test.ts:185-208 only checks a substring, so it doesn't catch the wrong wording. Six months from now, someone who needs to tell step diagnostics from declaration diagnostics will find that stepId sometimes holds an agent name. The field's contract is now implicit. Put the name in the agent field, which PreflightRefusal already carries for model_unknown, or give the resolution its own origin tag.

2. authored-flow-agents.ts:75-85. The surfaces key is spread twice. If both a stream and a workspace were set, the workspace spread would silently drop the stream. This is safe today only because of the early throw on line 50. That dependency isn't stated anywhere near the spreads, so anyone who relaxes the throw will reintroduce the bug. Build surfaces once, or add a comment tying the two together.

3. cli/check.ts:100-116, the readiness cache. The comment says "Refusals are never reused," and the code does skip caching refusals. No test would fail if it started caching them: the live test only checks that successes are reused (4 probes). A regression here would let a later override inherit an earlier failure or pass without being probed, and nothing would catch it.

4. cli/check.ts:79-81. checkAuthoredFlow is now a one-line wrapper. Its only caller is check.ts:69, and it is still named in docstrings (authored-flow-executor.ts:95-98, authored-flow-error.ts:34, and the test docstring at line 28). The docs now point at a wrapper instead of the checker that actually does the work, which is drift under AGENTS.md rule 6. Either inline it or update the references to createAuthoredFlowChecker.

5. Hand-bumped release manifests. Versions 2.0.8 → 2.0.9 appear in 8 package files. Past bumps came from the GitHub Actions chore(release) commit (f0a3b3bf). 2.0.9 is on npm and the integrity hashes match, so nothing is broken. Still, this PR mixes feature work with release metadata, and nothing records who published 2.0.9 or from which commit.

Notes

• surface/tests/flow.test.ts, "same captured proxy descriptor values". The test asserts descriptorReads === 2, which pins an exact implementation count rather than the behaviour. Any harmless refactor of snapshotHeader will break it. Asserting "validated value equals frozen value" is enough.
• preflight-cli.ts:17-24. The long governance comment about modelRegistryPath now sits above a single delegated call. The gate it describes lives in unknownAgentModels (line 222), and the step loop below the comment is never gated by it. Move the comment to where the gate is.
• authored-flow-agents.ts:96. The fallback message used to name flowPath; now it says "from the flow file". That makes a debugging clue less specific.
• docs/evidence/pr245/. The evidence is captured the way AGENTS.md §"Evidence is captured" asks. The mutation run is recorded correctly: the specific change is named, the failing and passing outputs are included, and bytes were restored. But it adds about 1,300 lines of logs containing absolute /Users/khaliqgant/... paths that will go stale. Consider whether this belongs in the PR body instead of the tree.
• SURFACE.md implementation-status paragraph. The text is accurate and names both front ends correctly.

history

Captured final verdict

Blockers

None. I found no repeated historical mistake, newly introduced contradiction with a settled RFC decision, or false commit-message claim in 00e62a57.

Concerns

The evidence has explicitly documented limits: the full SDK run predates the final model-syntax regression, and the named-agent live test exercises local wrappers rather than provider availability. docs/evidence/pr245/README.md discloses those limits and the failed root-directory invocation. These are evidence boundaries, not grounds for rejection under this lens. I did not independently rerun the tests.

Notes

• DRIVE-LOG records a previous cache defect where omitting resolution source conflated relative CLIs from different directories. The new execution cache retains the effective base directory and model alongside CLI identity in check.ts, preserving that distinction.
• DRIVE-LOG also records named-agent model loss during lowering. preflight-cli.ts retains the declared model when only the CLI is overridden. Its registry check also preserves commit a42ca161’s deliberate exemption for named declarations when no project config exists.
• The new agent path compiles through toKernelSpec and submits through journal.runStart in authored-flow-agents.ts. This remains consistent with settled decisions regressions: red/green flows for the 2026-08-27 platform bugs (dormant until gates 2+6) #5 and drive: WP-13: Fix SDK test failures from sandbox environment gaps #13.
• The commit’s claims about declaration preflight and retained refusals match authored-flow-executor.ts and the direct-run changes. Unsupported headers still refuse explicitly; the commit does not claim complete bundle or durability implementation.

structure

Captured final verdict

Blockers

None. The kernel remains pure Rust with no product logic; all changes stay in SDK/surface layers. File sizes are reasonable (new files: authored-flow-agents.ts 146 lines, authored-flow-output.ts 127 lines, preflight-cli.ts 229 lines, preflight-probe-error.ts 7 lines). The named-agent contract ships for both YAML and TS dialects via shared FlowSpec.agents/preflight resolution — one contract, two front‑ends. Header fields are refused closed (only agents supported, others error), aligning with "fail closed." The AuthoredFlowExecutionError gains a refusalKind field to preserve the closed refusal taxonomy (cli_missing, model_unknown, etc.) across the wrap from preflight to CLI output. All kernel tests pass (239 tests), and SDK tests pass from packages/sdk (127 focused, 941 full). The lowerAgent now correctly uses name to select named-agent declarations, with fallback to project defaults for unmatched names — the test "does not treat an unrelated f.agent name as a named-agent selector" verifies this. The createAuthoredFlowChecker caches probes within one execution, refusing reuses as intended. No primitives are added to the kernel; new files are focused helpers (authored-flow-agents, authored-flow-output, preflight-cli). The shape matches RFC-0001 and AGENTS.md.

Follow-up at b88244113be0ca330b01871fdd0588ac483e5f59 to the hosted maintainability review:

• C1: Failure and parked messages now select diagnostics by severity, so a trailing warning cannot hide the cause. Empty diagnostics still produce a typed refusal with the run ID. Both paths have regression tests.
• C2: Documented that journalSteps records observed journal facts. Runtime classification failures append nothing; malformed output retains an actual completion. Tests pin both behaviors. Rolling back journal facts would misrepresent the completed work.
• C3: Documented runtime exit classification: 0 success, 1 failure, 3 parked. Preflight refusals occur before runStart; the nonzero guard remains fail-closed. classifyOutcome does not return preflight exit 2.
• C4: Documented the existing policy distinction and added the exact absent/empty-model-list cases with a present registry: both refuse model_unknown before any CLI probe. The review's suggested fail-open behavior does not occur.
• C5: Documented the relative-path base on CliResolution.source. This remains a closed internal TypeScript union: project resolution uses the config directory; the other sources use the flow directory.

Commands and complete output for the follow-up build, typechecks, and 132-test run are in review-followup.txt. The prior full SDK/kernel/package evidence and its scope remain documented in the adjacent README.

The hosted structure lens is independently blocked by a provider spending limit. Read-only diagnostic command:

maintainability

Captured final verdict (exit 0)

Blockers

None. I found nothing that would make the code unsafe to change. There are several places where a future maintainer would be misled, though.

Concerns

1. Agent names are stored in the stepId field. preflightAgentDeclarations (packages/sdk/src/preflight-cli.ts, ~L200) pushes { stepId: agent, source: 'named', ... }. So probeResolvedCli refusals print Step "reviewer" declares CLI … when no step called "reviewer" exists. JSON consumers also get an agent name in diagnostics[].stepId. bindResolvedCliPaths (cli/check.ts:267) keys on stepId. If someone later routes a declarations() report through it, an agent named agent-1 would collide with the generated step id agent-1 (authored-flow-executor.ts, agent-${nextStep++}). The model-syntax and allowlist diagnostics already use an agent field; the probe diagnostics should do the same.

2. Comments point at code that has moved. tests/direct-input.test.ts (new test, ~L111) says the wrapping happens in "authored-flow-executor.ts's lowerAgent". That logic now lives in authored-flow-agents.ts. The comment also narrates history ("direct-run.ts used to then hardcode…") instead of stating the contract. A reader following it lands in the wrong file.

3. Header validation happens in three places with different message prefixes. snapshotHeader (surface/src/flow.ts ~L128) runs first and uses the prefix unsupported_header: flow "X" header, which puts an SDK error code inside the surface package. assertFlowHeader then uses header.…. freezeHeader calls ownDataEntries(header.agents) again on data that is already inert. It isn't clear which pass is authoritative. The accessor test only passes because it matches a substring of the message. Once the snapshot exists, the second descriptor walk in freezeHeader can go.

4. Type-only import cycle. authored-flow-output.ts and authored-flow-agents.ts import AuthoredFlowJournalStep from authored-flow-executor.ts, and the executor imports both of them. It's harmless today, but moving the type into a leaf module (e.g. authored-flow-error.ts) would stop someone later adding a value import that breaks module init order.

5. The error-mapping catch is copied. createAuthoredFlowChecker (cli/check.ts ~L117 and ~L140) has the same CheckFailure→report catch twice. A change to one copy will quietly diverge from the other.

Notes

• Good caching contract. Only successful probes go in the checker's cache, keyed by canonical CLI, base directory and model; refusals are always re-probed. It's documented in place, and live-named-agents.test.ts pins it: exactly 4 probes for 2×2 CLI/model pairs, with the unused alias adding none.
• Tests that would actually fail. authored-agent-failure.test.ts pins that the classified diagnostic is chosen over a trailing warning, and that journalSteps stays append-only. The negative control in named-selection-mutated.txt shows the live test catches a broken selector, which meets AGENTS.md's bar for mutation verification.
• Evidence ages quickly. The files under docs/evidence/pr245/ contain absolute /Users/khaliqgant/... paths and test counts that differ between runs (6 vs 7 named-agent tests; the README explains why). That's fine as a PR record, but nobody will keep it current. Consider linking to it from the PR description instead of keeping it in docs/ long term.
• Hard failure without a built daemon. live-named-agents.test.ts throws in beforeAll if the daemon isn't built, where it could skip. That fails closed, but other live suites locate the binary differently (locateRelayflowd). Sharing that helper would keep them consistent.
• Formatting nit. There's a double blank line in authored-flow-output.ts before isRecord.

history

Captured final verdict (exit 0)

Blockers

None. I found no repeated DRIVE-LOG mistake, newly introduced contradiction with a settled RFC decision, or false claim in commits 00e62a57 and b8824411.

Concerns

The full SDK transcript predates the final changes. docs/evidence/pr245/README.md, lines 3–15, explicitly distinguishes that run from the later focused verification and retains the unsuccessful invocation. This limits what the full-suite evidence establishes, but does not constitute an untruth or blocker. I did not independently rerun these tests.

Notes

• The drive log records a previous cache regression where omitting resolution source confused relative executables from different directories. packages/sdk/src/cli/check.ts, lines 106–114, preserves the relevant distinction through the resolved CLI, source-dependent base directory, and model. This does not reintroduce that mistake.
• The extraction preserves commit a42ca161’s deliberate no-registry exception. packages/sdk/src/preflight-cli.ts, lines 217–229, still enforces named-agent allowlists when a registry exists and permits readiness probing when none exists.
• Named selections and overrides compile through the existing spec and journal boundary in packages/sdk/src/authored-flow-agents.ts, lines 66–108. That is consistent with settled decisions 5 and 13; the extraction introduces no new kernel vocabulary.
• Both commit messages match their changes: declaration validation, shared readiness checks, module extraction, and preserved failure diagnostics. packages/sdk/src/authored-flow-executor.ts, lines 130–145, checks declared agents before body execution while retaining refusals for unsupported headers. Existing scaffolding is not newly represented as complete.

Rebase deferred — heavy overlap with landed spec slices

Tried to rebase feat/ts-named-agents onto current origin/main. Result: 8 conflict files, 2681 additions vs 513 deletions on the branch, and the core commit's stated scope now overlaps substantially with landed spec slices.

Merged since #245 was opened that subsume the scope

• feat(surface,sdk): named agent flow composition via use: — surface + loader (#300) #328 (feat(surface,sdk): named agent flow composition via use: (surface + loader)) — SURFACE §slice D. Handles named agent declaration + preflight validation via use:. Covers "capture and validate immutable header declarations" and "check every declared agent before entering the body."
• feat(surface,sdk): expose cli/model on Ctx.agent options (#310) #311 (feat(surface,sdk): expose cli/model on Ctx.agent options) — SURFACE flows: Ctx.agent has no cli/model options in TypeScript — SURFACE §2 rule 6 gap #310. Per-step CLI/model on Ctx.agent, TS parity with YAML use: overrides.
• feat(sdk): lower f.llm in the TS surface + declarative output binding (#273 #275) #296 (feat(sdk): lower f.llm in the TS surface + declarative output binding) — SURFACE flows: flagship llm chain has no executable local path in YAML or TypeScript #273/flows: declarative steps lack a supported way to consume upstream output #275. TS f.llm executor path + declarative bindings.
• fix(preflight): inline named-agent model without flows.json (#263) #266 (fix(preflight): skip model_unknown for inline named agents when no flows.json is present) — SURFACE flows: inline named-agent { cli, model } shouldn't require a mandatory external flows.json model allow-list #263. Inline named-agent model support.

What #245 has that may still be unique

Skim of the diff (kept only from mechanical read, worth manual review):

1. preflight-cli.ts extraction — 229-line refactor pulling CLI preflight policy out of preflight.ts. Not obviously in main.
2. Readiness-probe caching within an authored execution — commit message says "Reuse successful readiness probes within an authored execution while checking independent CLI and model overrides." Worth checking whether merged slices already do this.
3. authored-flow-output.ts (133 lines) — journal output decoding separated. Not obviously in main.
4. Dedicated named-agent test suites — authored-named-agents.test.ts, live-named-agents.test.ts, authored-agent-failure.test.ts (~458 lines). Might not fully overlap with test coverage added by feat(surface,sdk): named agent flow composition via use: — surface + loader (#300) #328/feat(surface,sdk): expose cli/model on Ctx.agent options (#310) #311/feat(sdk): lower f.llm in the TS surface + declarative output binding (#273 #275) #296.
5. docs/evidence/pr245/ — captured verification bundle; documentation-only, no runtime impact.
6. Agent-failure-diagnostic preservation (fix commit b88244) — "preserve authored agent failure diagnostics and pin failure contracts." Worth checking if feat(sdk): lower f.llm in the TS surface + declarative output binding (#273 #275) #296 or later covers this.

Recommendation

Rather than force-resolve 8 conflicts on a 2181-line delta whose intent is already largely on main, one of:

• Close the PR and cherry-pick anything genuinely missing as a small follow-up (readiness-probe cache, preflight-cli extraction if it improves layout, missing test cases as regression coverage).
• Re-scope: reset the branch to just the still-unique pieces (probe cache + tests + diagnostics fix) and open as a small targeted PR against current main.

Not force-pushing a stale rebase. Deferring to Khaliq's judgement on close-vs-rescope since this is his own PR.

Rebase attempted from fl-245-rebase worktree; conflicts in packages/sdk/{package.json, package-lock.json, cli/check.ts, cli/direct-run.ts, preflight.ts, authored-flow-executor.ts}, packages/surface/{context.ts, flow.ts}.
