* fix(sveltekit): patch server chunks with rollup-renamed __filename bindings
The adapter-node chunk patch skipped any chunk matching
/\b(const|let|var)\s+__(file|dir)name\b/ — but $ is not a regex word
character, so rollup-renamed declarations like `__filename$1` (produced
when adapter-node re-bundles the intermediate server output and our
banner's declaration collides) satisfied the check. Chunks that declared
only a renamed binding while a bundled CJS dependency referenced the
bare `__filename` were skipped, and the production server crashed at
boot (observed on main with the TypeScript compiler bundled via
cosmiconfig through @workflow/world-postgres).
Anchor both regexes with (?![\w$]) so renamed identifiers no longer
match. Verified: the sveltekit workbench production server now boots and
serves health checks (with and without a base path), and queue
deliveries from start() succeed.

* fix(sveltekit): keep the TypeScript compiler out of the server bundle
Since the world-target injection change, the sveltekit workbench's
hooks.server.ts imports @workflow/world-postgres, whose dependency chain
(graphile-worker -> cosmiconfig) reaches cosmiconfig's TS-config loader.
At runtime that loader's require('typescript') is lazy and never fires,
but SvelteKit bundles the whole chain into the server and rollup's CJS
conversion hoists it into an eager top-level evaluation — executing the
entire TypeScript compiler at boot and crashing the server
("__filename is not defined" inside the bundled compiler).
Alias 'typescript' to a stub module in the SvelteKit plugin, following
the existing pg-native pattern. Server output shrinks from 36MB to 11MB
and boots cleanly.
Verified: sveltekit workbench production build boots, serves
flow?__health (200), and start() runs execute with clean queue
deliveries. The chunk-patch regex fix from the previous commit stays as
hardening for any other CJS dependency that references __filename.

Inline source maps are embedded in the step bundle and the intermediate

the Vercel 250MB limit) even though maps only help when reading a stack trace.
Make the default environment-aware in @workflow/builders: inline in
development (next dev / nitro dev / Vite-based dev servers, detected via
config.watch or NODE_ENV=development) and off in production. The `sourcemap`
config option and `WORKFLOW_SOURCEMAP` env var still override in either
environment. A production build with no override also drops the
source-map-support shim from the Vercel step function.
Keep runtime stack remapping graceful and fast when maps are absent
(@workflow/core): short-circuit when no frame references the workflow file
and memoize the parsed map (or its absence) per bundle, so production failures
don't rescan the bundle.

* test(e2e): make source-map expectations match dev-on/prod-off default
The e2e error-stack tests gate source-map assertions on hasWorkflowSourceMaps()
and hasStepSourceMaps(). Now that source maps default to off in production
builds, update those helpers:
- hasWorkflowSourceMaps(): false for all production builds (local prod,
postgres, Vercel — keyed off DEV_TEST_CONFIG), and exclude nest in dev (the
Nest integration builds with watch:false / no NODE_ENV=development, so its
bundles have no maps).
- hasStepSourceMaps(): nest now resolves to a production build (maps off) in
both dev and prod.
Add unit cases for the dev-vs-prod and nest behavior.

* Validate unique step ids at build time
* Fall back to file-path IDs for non-exported package files
Instead of synthesizing a 'name/dist/<path>@version' specifier (which
hardcoded the dist/ output convention), non-exported workspace/node_modules
files now return moduleSpecifier: undefined and let the SWC plugin's
'./{filepath}' fallback produce per-file IDs. This is the same path local
app files have always taken and avoids the dist/ assumption flagged in
review. The build-time duplicate-ID check stays as the safety net.
* Dedupe virtual-entry imports by canonical module identity
When both the source and the compiled-dist copies of the same workspace
package export end up in discoveredSteps/discoveredWorkflows (e.g. the
'workflow' package's internal/builtins in monorepo dev), they resolve to
the same module via esbuild's package resolution. The virtual entry was
emitting BOTH 'import "workflow/internal/builtins";' (the built-in
preamble) and 'import "../../packages/workflow/src/internal/builtins.ts";'
(via the isWorkspaceSourceBackedPackageFile carve-out in createImport),
which made the swc plugin transform both copies and generate duplicate
step IDs.
Track a per-bundle set of emitted module identities (package specifier
when reachable, otherwise the file path) and skip files whose identity
has already been imported. The steps bundle pre-seeds the set with the
built-in steps specifier so workspace step files at that path don't
emit a competing relative-path import.
* Stop rewriting workspace package /dist/ -> /src/ during Next.js discovery
The Next.js deferred builder's `resolveSourceBackedPackagePath` rewrote
any discovered `/dist/` path to its `/src/` sibling for workspace
packages and for `workflow`/`@workflow/*` tarballs. That made the
discovered step file list point at source files while base-builder's
esbuild bundle (which builds the workflow VM and step registrations)
resolved the same package imports through `pkg.exports` to
`/dist/`. The workflow proxy ID — generated from the dist path —
didn't match the step bundle's registration ID — generated from the
src path — producing "Step function not registered" failures at
runtime, most visibly with @workflow/ai's doStreamStep on Vercel and
Windows Next.js deployments.
App code that imports a package by name should resolve naturally
through pkg.exports; the loader has no business reaching into the
package's source tree. Drop the rewrite (and the now-unused
`resolveCopiedStepImportTargetPath` helper that supported it).
Workspace packages are still discovered — that's a separate predicate
(`shouldPreferSourceBackedPackagePath`) which only gates inclusion,
not path translation.
Verified locally with the nextjs-turbopack workbench: agent e2e suite
(19 tests, including the failing `agentBasicE2e`) and the
addTenWorkflow duplicate-name suite all pass.

* Warn when serverExternalPackages hides workflow-enabled packages
Add a build-time warning when packages in serverExternalPackages contain
workflow code ('use step', 'use workflow', or serialization classes).
These packages are completely invisible to the workflow compiler when
externalized, causing silent runtime failures.
The warning detects workflow patterns via two methods:
- Fast path: check package.json dependencies for @workflow/serde
- Thorough path: read the package entry file and run pattern detection
Also adds documentation in the serialization guide about the
externalization footgun for 3rd-party packages.
* Auto-remove workflow packages from serverExternalPackages
When workflow-enabled dependencies are externalized in Next.js, compiler transforms are skipped and runtime failures follow. Detect those packages in withWorkflow, remove them from serverExternalPackages for the current build, and keep a generalized externalPackages warning fallback for non-Next builders.

Phase 2: Add four context-violation error classes to @workflow/core
(NotInWorkflowContextError, NotInStepContextError,
NotInWorkflowOrStepContextError, UnavailableInWorkflowContextError)
and apply them to all twelve user-facing throw sites so errors now
include docs links and a structured "what/why/fix" frame.

* Address review: tighten changeset, implement ansifyName, harden Ansi
- Tighten phase 1 changeset to a single sentence (per pranaygp review) and switch to double-quoted frontmatter (per Copilot + repo convention).
- Implement `ansifyName` to actually apply dim styling to workflow/ / step/ prefixes; add an `Ansi.dim` helper to `@workflow/errors` so callers don't need to import chalk directly.
- Remove the `void getWorkflowMetadata;` workaround in context-errors.ts by dropping the unused value import (we only needed the type and symbol).
- Render the plain-Error throw in `workflow/get-workflow-metadata.ts` with `Ansi.frame` + docs link so the VM path matches the structured-class styling from the sibling step path (still uses a plain Error to avoid the module-init cycle).
- Guard `buildUnderline` against zero-length markers so a stray empty token can't produce a negative `String.repeat` count.
* Structured runtime logger metadata + fold in replay-timeout logging
Adds a `.child()` and `.forRun(runId, workflowName)` child-logger API to
the structured logger so runtime/step code doesn't have to repeat
`workflowRunId`/`workflowName`/`stepId` on every call. Normalizes error
metadata to structured `errorName` / `errorMessage` / `errorStack` fields
instead of ad-hoc `error: err.message` strings, and adds comments to
silent catches that swallow expected idempotency conflicts.
Also folds in the pending changes from #1812 so that PR can be closed:
- Standardize the console prefix to `[workflow-sdk]`.
- Split the replay-timeout log into a warn-while-retrying vs.
error-when-giving-up, and surface the underlying error when we can't
mark a timed-out run as failed.
- Include the error stack in the "Fatal runtime error during workflow
setup" log and in the top-level user-code workflow error log so the
stack surfaces in flattened log drains.
- Drop the `[Workflows] "<runId>" - ` prefix from
`buildWorkflowSuspensionMessage` — the structured logger now attaches
run context.
Supersedes #1812.

* Use double-quoted changeset frontmatter per repo convention
* Add SerializationError + apply to user-facing serialization sites
Phase 4 of friendlier errors: introduce a `SerializationError` class with
an optional `hint` and a docs link (workflow-sdk.dev/err/serialization-failed),
and adopt it at every user-facing serialization boundary in @workflow/core:
- Locked ReadableStream at a workflow boundary
- Unregistered class / missing `classId` / missing `WORKFLOW_DESERIALIZE`
- Attempting to return step functions to clients or call workflow functions
directly
- Webhook `respondWith()` called outside a step
- `dehydrate*` / `getSerializeStream` failures (workflow args/return, step
args/return, stream chunks)
Internal invariants (format prefix length checks, unknown format bytes,
missing `STREAM_NAME_SYMBOL`, encryption key/size guards, etc.) now throw
`WorkflowRuntimeError` instead of plain `Error` so the classifier and logger
treat them consistently.
`formatSerializationError` now returns `{ message, hint }` so the hint
fragment can be rendered with the standard SerializationError framing
instead of being baked into the message string.

* Use double-quoted changeset frontmatter per repo convention
* Presentation-only user vs SDK error attribution
Add describeError() that derives attribution and class-aware hints from
existing error classes + RUN_ERROR_CODES — no event data changes. Wire into
step failures, max-delivery exhaustion, run failures, and fatal setup errors
so terminal logs include errorAttribution and a hint for known error types.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
* Address review: describeError accepts precomputed errorCode + instanceof
- `describeError(err, errorCode?)` now accepts an optional precomputed
`RunErrorCode`. `classifyRunError(err)` only narrows to USER_ERROR /
RUNTIME_ERROR, so the REPLAY_TIMEOUT and MAX_DELIVERIES_EXCEEDED branches
were previously unreachable from the step / run failure log sites.
Callers that know the failure category (runtime.ts for replay timeout and
max-deliveries exhaustion) now pass the code in.
- Context-violation checks use `instanceof` against the actual classes from
context-errors.ts instead of a name-string set. Type-safe + survives
class renames.
- Wire the new hints through to the REPLAY_TIMEOUT and MAX_DELIVERIES_EXCEEDED
log sites so those branches actually render a hint now.
- 3 new tests cover the reachable code paths + precomputed-code override.
- Changeset frontmatter switched to double quotes per repo convention.
* Cosmetic consistency pass on remaining bare throws
Internal invariants now use WorkflowRuntimeError so describeError attributes
them to the SDK: missing startedAt, VM generateKey, closure-vars outside
step context, ENOTSUP. defineHook().resume() formats schema validation
failures as a readable list instead of a JSON blob.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
* Use double-quoted changeset frontmatter per repo convention
* Data-driven describeRunError + expose via @workflow/core/describe-error
Observability renderers read persisted run_failed / step_failed event data,
not live Error instances. describeRunError takes { errorCode, errorName }
and returns the same { attribution, hint } shape as describeError, so the
CLI and web UI can derive user-vs-SDK framing from the event log directly.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
* Friendlier build-time errors: WorkflowBuildError class + applications
Add `WorkflowBuildError` class in `@workflow/errors` with optional `hint`
for an actionable next step, and apply it in `@workflow/builders` at
user-facing sites: failed esbuild phases, unresolved built-in steps, and
empty esbuild output now throw `WorkflowBuildError` with a hint pointing
at the likely fix. Runtime invariants remain plain `Error`.
* Polish friendlier-errors rendering: drop functionName leak, simplify docs link, redirect stack
- Drop the readonly `functionName` param-property on context-error classes so
util.inspect no longer prints a trailing `{ functionName: 'foo()' }` block.
- Replace the `DocLink` ("label: https://…") shape with a plain `DocsUrl`
template-literal type. Error output now renders a single clean line:
`docs: https://…` (new `Ansi.docs` helper) instead of the noisier
"note: Read more about foo(): https://…".
- Add throw helpers (`throwNotInWorkflowContext`, etc.) that call
`Error.captureStackTrace(err, stackStartFn)` on V8 engines so the top frame
of the thrown error points at the user's call site instead of at the gate
function inside the framework. Callers pass themselves as the boundary.
- Refactor `defineHook()` (both root and `/workflow`) to use named function
closures rather than `this.create`/`this.resume`, since the stack redirect
relies on a stable function identity that survives destructuring.
- Update context-errors.test.ts to snapshot the new `docs:` framing and to
add a regression test asserting the top stack frame is the user call site.
* Consolidate friendlier-errors stack: fix ANSI leak + non-retry semantics
Addresses PR review feedback across the 8-phase friendlier-errors stack and
fixes issues surfaced by manual testing (createHook() inside a step):
- ANSI no longer leaks into .message / .stack. Context-violation errors
now store plain text on .message and render the colored framed form
lazily via [util.inspect.custom] / toString(). Structured logs, log
drains, CBOR-serialized events, and JSON payloads no longer contain
raw \x1B[...m bytes.
- Context violations are now fatal. ContextViolationError sets
fatal = true; FatalError.is(err) recognizes any error with a
fatal: true own property. Calling createHook() from a step no longer
burns three retry attempts on a guaranteed-to-fail context violation.
- Ansi helpers moved to @workflow/errors/ansi subpath so imports from
@workflow/errors no longer pull chalk into consumers that only want
error classes (addresses reviewer VaguelySerious).
- Shared redirectStackToCaller helper in packages/core/src/capture-stack.ts,
used by both context-errors.ts and workflow/get-workflow-metadata.ts
(addresses Copilot review on #1849).
- Structured framed content: ContextViolationError now takes a structured
FramedContent (title segments + detail branches) and renders plain/pretty
from the same source of truth.
Tightens the eight existing phase changesets to 1-2 sentences each and adds
four new scoped changesets (errors-ansi-subpath, context-errors-plain-message,
context-errors-fatal, capture-stack-shared) for the followup fixes, so the
final changelog history stays readable.
* test: update step-handler mocks for scoped forRun() logger
The runtime logger now uses .forRun(runId, name, {stepId, stepName})
to attach scope context, so 409-handling log calls no longer repeat
{workflowRunId, stepId} in every metadata bag — those live on the
scoped logger instance. Update the mock to return itself from forRun()
and tighten assertions to check both the log args (errorName/errorMessage)
and the forRun() scope.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
* Mark SerializationError fatal + route dehydration through step-failure path
SerializationError now carries readonly fatal = true. Step-return
dehydration is wrapped inside the user-code try/catch so that the
resulting error flows through userCodeFailed → step_failed →
FatalError.is() short-circuit instead of bubbling up as HTTP 500 and
triggering a queue retry loop. Retrying a step that returned a non-POJO
is guaranteed to fail the same way, so this saves ~20s and 3 near-
identical error blocks per serialization failure.
* Add logging snapshot tests + manual-test artifacts
Snapshot tests lock in the exact shape of:
- describeError() payloads (attribution, errorCode, hint) for every
classification — plain Error, SerializationError, context-violation,
WorkflowRuntimeError, REPLAY_TIMEOUT, MAX_DELIVERIES_EXCEEDED.
- The scoped-logger call signature for the two canonical runtime
failure paths (fatal-bubble and hit-max-retries), so refactors of
forRun() / child() metadata merging can't silently change what users
see in their log drains.
SerializationError now also has a direct test for readonly fatal=true
+ FatalError.is() recognition.
pr-artifacts/ contains real log-output snapshots from running the
nextjs-turbopack workbench against five error scenarios. These are
reference material for reviewers and are flagged to be removed before
merge.
* Readable step-fatal logs: inline stack + friendly step/workflow names
The step-level fatal-error log used to embed the full stack trace inside
an `errorStack` string field in the metadata object, so util.inspect
rendered it as a quote-escaped, line-continuation blob when the log
hit the terminal — unreadable in practice. Move framing + stack into
the log *message* (matching the workflow-level log in runtime.ts) and
keep the metadata object compact with only the indexable structured
fields (`errorAttribution`, `errorName`, `errorMessage`, `hint`,
IDs). Log drains still get the same keys; humans now see a readable
stack trace.
Also introduce `formatStepName` / `formatWorkflowName` in
`@workflow/utils` that render machine names
(`step//./workflows/1_simple//add`) as `add (./workflows/1_simple)` in
log framings, using the existing `parseStepName` / `parseWorkflowName`
parsers. Applied to step-fatal, hit-max-retries, exceeded-max-retries,
and workflow-threw log sites.
Artifacts in pr-artifacts/ updated to show the new output shape, and
renamed .log → .md since they're Markdown and IDE previews are nicer
that way.
* Opinionated pretty formatter for runtime structured-log metadata
Replace util.inspect's default object dump (which quote-escapes
multi-line stacks and paragraph hints into a single-line JSON-y blob)
with a workflow-aware formatter that composes the entire log line
into a single string passed to console.error / console.warn.
Highlights of the new output:
- Per-run / per-step IDs render with their parsed friendly names so
users see `wrun_… · simple (./workflows/1_simple)` instead of just
the raw `workflowName: 'workflow//./workflows/1_simple//simple'`.
- Color-coded attribution badge (user error red / sdk error magenta)
paired with the error class in bold.
- Hints render as a paragraph under `hint:` rather than a backslash-
`\n`-escaped string.
- Drops redundant fields (errorStack always; errorMessage when it's
already in the parent message) to avoid double-printing.
- Unknown fields fall through as a sorted `key value` tail so we
never silently drop log information.
@workflow/errors/ansi gains bold/red/magenta helpers used by the
formatter. The web / web-shared packages don't consume stderr — they
read structured event payloads from the World event log — so this is
presentation-only at the runtime layer.
* ci(benchmarks): disable pnpm cache for getCommunityWorldsMatrix
The job never runs `pnpm install` (it just calls `node` against a
checked-in script), so the pnpm store path never exists. The post-job
`actions/setup-node@v4` cache-save then fails with `Path Validation
Error: Path(s) specified in the action for caching do(es) not exist`
and red-X's the entire job even though the matrix step succeeded.
The setup-workflow-dev composite already has a `cache-pnpm` opt-out
input for this exact case — wire it through here.
* Address PR review comments: inspect dedup, cause leak, retry-loop tests
- ContextViolationError: util.inspect(err) duplicated every framed detail
line because the stack-tail strip only sliced the first message line.
V8's Error.stack reads `Name: messageLine1\n messageLine2\n at ...`,
so for our multi-line `title\n╰▶ docs: …` messages every detail line
was getting prepended twice (once in the pretty form, once via the
unsliced message tail). Count the actual message lines and slice past
all of them. Repro test asserts `╰▶ docs:` appears exactly once.
- WorkflowError: stop assigning `cause: undefined` as an enumerable own
property when no cause is provided. Subclasses (every error in this PR)
inherit the parent constructor; the unconditional assignment polluted
`util.inspect(err)` output with `{ cause: undefined, … }` on every
no-cause instance. The `super(...)` call already conditionally sets
`.cause` non-enumerably when `options.cause` is provided.
- step-handler.test.ts: add a regression-gate suite that exercises the
fatal-vs-retryable retry-loop wiring directly. Asserts that an error
with `fatal: true` produces exactly one `step_failed` event with no
`step_retrying`, and that a non-fatal `Error` retries via
`step_retrying` on early attempts and emits `step_failed` once the
retry budget is exhausted. Catches the silent-regression case where
`fatal = true` is removed from a context-violation error class but
the `FatalError.is()` unit tests stay green.
* Consolidate changesets + remove pr-artifacts
Address review feedback to drastically shorten the changesets — fold
the 15 file-by-file entries into a single user-facing changeset for
@workflow/core / errors / builders / utils. Also drop the pr-artifacts/
folder (reviewer-only log captures, no longer needed).
* Polish runtime error logging: layout, stack trim, hint consolidation
Five user-driven fixes from manual smoke-testing of #1849:
1. Logger layout. composeLogLine() now puts the structured-fields block
(attribution badge, run/step IDs, error code) **between** the framing
line and the stack body, instead of after it where 30+ lines of stack
buried the most useful information. The framing stays at the top,
stack at the bottom, structured info readable at a glance.
2. Stack trim. Drops framework-internal frames (`node_modules/.pnpm/`,
`node:internal/`, Turbopack-bundled `node_modules__pnpm_*` chunks,
`_next_dist_*` chunks) and caps the surviving frame count at 6
so the stack stays compact even on heavy async wrappers. Suppressed
runs emit one summary line so users know the trim happened.
3. Wrapper-route noise. The nextjs-turbopack workbench's start route
was catching `WorkflowRunFailedError` rejection on
`Promise.race([readLoop(), run.returnValue])` and re-logging it via
`console.error('Error in workflow stream:', error)` plus
`controller.error(error)` — which then triggered Next.js's
`⨯ failed to pipe response` overlay. The SDK already logs the
failure cleanly upstream and the runId is on the response header, so
the wrapper now closes the SSE stream cleanly on
WorkflowRunFailedError.
4. Consistent framed `╰▶ hint:` / `╰▶ docs:` layout for all errors
that carry a hint or docs slug. WorkflowError, SerializationError,
and WorkflowBuildError now share one `appendFramedDetails` helper
matching the box-drawing structure that ContextViolationError
already used. Was: blank-line-separated `Learn more: <url>`. Now:
one tree, indistinguishable from context-violation rendering.
5. Drop the duplicate logger-side `hint` field. Hints now live on the
error message only — actionable hints get serialized into the event
log, rehydrated on the workflow side, and shown in observability
automatically. The previous logger-only hint duplicated stderr but
never made it past the step boundary.
Updated SerializationError hint to point at the foundations doc
("Ensure you're returning workflow serializable types. Check the
serialization docs to see what's serializable:
https://workflow-sdk.dev/docs/foundations/serialization") instead
of the hardcoded `(plain objects, arrays, primitives, …)` list,
which drifted out of sync as the supported types grew. Same hint
reuses for step args, workflow args/return, stream messages, and
any other site that goes through `formatSerializationError`.
Also retitled the retry summary `3 retries` → `3 max retries` since
"3 retries" next to "4 attempts" was ambiguous (already-happened vs.
budget).
* Trim error-card title + drop machine step name from persisted error
- ErrorStackBlock (web observability): show just the first non-empty
trimmed line of the error message in the card title with single-line
truncation. Multi-line messages (`Failed to serialize step return
value\n╰▶ hint: …`) were rendering the entire framed body in the
title, pushing the copy button off-screen and burying the
scannability of the headline. Full message stays in the body via
the stack (V8 prepends `Name: message` to `Error.stack`), so no
information is lost; hover-tooltip exposes the full title text.
- Persisted error message: drop the `Step "step//./.../foo"` machine
name from `Step failed after N retries: …` and `Step exceeded max
retries (…)` strings. Observability already attributes the event
to a specific step via the UI tree, and the CLI logger emits the
friendly `Step foo (./...) hit max retries` framing on its own
line. Embedding the raw `step//./...` machine name in the persisted
message text was duplicate noise.

* Update SerializationError snapshot tests for slug-less message
The class no longer attaches a slug-based `╰▶ docs:` line — the
foundations URL is embedded directly in the hint via the
`formatSerializationError` helper in @workflow/core. Update the test
expectations accordingly:
- bare-title case is now a single line (no docs link)
- hint case renders one `╰▶ hint: …` branch (no second branch)
* Update serialization.test.ts hint assertions for foundations URL
Four `should throw error for an unsupported type` cases were still
asserting on the old hardcoded type list. Update to the new hint
phrasing that points at the foundations doc, matching the change in
`formatSerializationError` (`packages/core/src/serialization/errors.ts`).
