* Add cookbook section with 50 workflow pattern recipes
Migrate the "Workflow API Explorer" decision tree concept from
workflow-campaign-demos into useworkflow.dev docs as a Cookbook.
Infrastructure:
- docs/lib/cookbook-tree.ts: decision tree data, 50 recipe metadata entries, slug-to-category mapping
- docs/components/geistdocs/cookbook-explorer.tsx: interactive "I want to..." decision tree UI with breadcrumb navigation
- docs/content/docs/cookbook/index.mdx: landing page rendering CookbookExplorer component
- docs/content/docs/cookbook/meta.json + 8 category meta.json files for sidebar nav
- docs/content/docs/meta.json: added cookbook to docs nav between foundations and how-it-works
- docs/app/[lang]/docs/[[...slug]]/page.tsx: registered CookbookExplorer component
50 recipe MDX files across 8 categories (payments, approvals, resilience,
notifications, webhooks, data-processing, routing, observability), each with:
- Frontmatter (title, description, type: guide, summary with use-case scenario)
- Simplified code snippet (core pattern only, stripped of demo UI concerns)
- Full implementation code snippet (exact source from campaign demos)
- Key APIs section with links to API reference docs

* fix: polish cookbook public routing
Keep the cookbook surface canonical at /cookbooks so docs navigation, sitemap output, and AI/chat entry points stop leaking the legacy /docs/cookbook paths.
Correct the approval-chain example so the docs teach the intended sequential approval semantics instead of implying the workflow approves after the first successful level. This keeps the cookbook aligned with the docs quality bar and avoids misleading readers with inconsistent behavior.

* docs: canonicalize cookbook doc routes
Align cookbook-facing docs outputs with the new public route so
redirects, sitemap entries, and LLM-facing exports stay consistent.
This keeps the polished cookbook section discoverable at its canonical
location while trimming the last demo-heavy recipe examples toward the
same concise style as the rest of the docs.

Ploop-Iter: 4
* fix(docs): finalize cookbook route split
Keep cookbook content discoverable after moving it to a first-class /cookbooks surface so navigation, canonical metadata, and markdown consumers resolve the new public URLs consistently.
Avoid serving the legacy /docs/cookbook tree as if it were still part of the docs section, which reduces duplicate navigation paths and prevents stale static output from competing with the new route structure.
Ploop-Iter: 5
* docs: improve cookbook discovery
The cookbook landing page needs to work for both exploratory users and users who already know the pattern they want. This keeps the guided decision tree while adding shared category metadata and a searchable browse mode so recipe discovery feels faster and more consistent with the rest of the docs experience.
Ploop-Iter: 6
* docs: refine cookbook pattern examples
Tighten the simplified cookbook recipes so the examples teach the intended workflow semantics clearly and consistently. The changes keep the documentation focused on the core control-flow patterns reviewers called out, while removing ambiguity around partial arrivals, deadlines, and first-success behavior.
Ploop-Iter: 7
* docs: decouple cookbook sidebar tree
Separate cookbook navigation from the docs page tree so the standalone /cookbooks experience stays stable after the route move and the main docs sidebar no longer leaks cookbook entries.\n\nThis keeps cookbook navigation driven by explicit recipe metadata, which avoids duplicated section titles and makes the docs and cookbook surfaces easier to evolve independently.\n\nPloop-Iter: 8
* fix(docs): align cookbook public nav
Keep cookbook pages on their public /cookbooks surface so metadata and copied markdown do not leak legacy /docs/cookbook paths.\n\nSimplify sidebar rendering to trust the injected page tree, which avoids route-specific filtering and keeps cookbook navigation consistent with the active layout tree.\n\nPloop-Iter: 9
* refactor(docs): decouple cookbook routing
Move cookbook rendering off the shared docs route so cookbook pages can behave like a first-class docs surface without leaking cookbook-specific UI into the main docs experience.
Centralizing cookbook tree filtering keeps sidebar behavior consistent in one place and avoids duplicate cookbook navigation state across layouts.
Ploop-Iter: 10
* docs: improve cookbook explorer accessibility
Improve the cookbooks entrypoint so loading and keyboard navigation
are usable without visual cues, and keep guided and browse modes
resilient while the route hydrates.
Ploop-Iter: 11
* ploop: iteration 12 checkpoint
Automated checkpoint commit.
Ploop-Iter: 12
* docs: rename cookbooks route to cookbook (singular)
* docs: add 5 cookbook overview design variations
Add getRecipeHref, getRecipesByCategory, and collectSlugs helpers to
cookbook-tree.ts, then create 5 distinct overview page variations at
/cookbook/v1 through /cookbook/v5 for side-by-side comparison:
- v1: Category Grid (zero-JS scannable overview)
- v2: Search-First (real-time filtering with category pills)
- v3: Accordion Catalog (expandable category sections)
- v4: Decision Wizard (step-by-step guided questions)
- v5: Problem-Solution Table (master-detail by scenario)
Also adds .impeccable.md with project design context.
* docs: remove unrelated package.json bumps and generated artifacts
* docs: restructure cookbook from 50 recipes into 27 consolidated pages
Restructure the cookbook based on team meeting feedback, toolbar comments,
mux-ai pattern analysis, and Vercel org code search. Consolidates duplicates,
adds missing patterns, ensures all examples have proper directives and
type-check against the real workflow SDK.
New structure:
- common-patterns/ (9): saga, batching, rate-limiting, fan-out,
scheduling, idempotency, webhooks, content-router, child-workflows
- agent-patterns/ (5): durable-agent, tool-streaming,
human-in-the-loop, tool-orchestration, stop-workflow
- integrations/ (3): ai-sdk, sandbox, chat-sdk
- advanced/ (6): serializable-steps, durable-objects,
isomorphic-packages, secure-credentials, custom-serialization,
publishing-libraries
All 92 code snippets pass docs-typecheck against real workflow SDK types.
Deleted 8 old category folders. Updated cookbook-tree.ts, explorer, nav.
* docs: add workflow migration guides
Help teams evaluating the GA launch translate existing durable workflow systems into Vercel Workflow without reverse-engineering concept parity from product docs alone.
The guides focus on real migration decisions and concrete TypeScript examples so adoption can be driven by implementation clarity rather than platform marketing.

Ploop-Iter: 2
* docs: refine workflow migration guides
Clarify the migration narrative for GA so teams evaluating a move from Temporal, Inngest, or Step Functions get examples that are realistic enough to trust and pricing guidance that matches the current platform model.
The Inngest guide needed a complete order-saga flow so the durable orchestration, compensation, and streaming patterns read as a credible migration target instead of a partial sketch. The pricing language across all three guides also needed to be aligned with current Workflow and Vercel compute billing semantics to avoid creating the wrong cost expectations during evaluation.

* docs(skill): refine workflow migration guidance
Clarify migration rules so agents choose the correct resume primitive, keep streaming guidance aligned with runtime behavior, and avoid implying Vercel-managed execution for self-hosted targets.
This reduces avoidable migration mistakes in generated guidance and keeps the skill consistent with the acceptance criteria used to evaluate it.

* ploop: iteration 3 checkpoint
Automated checkpoint commit.
Ploop-Iter: 3
* docs(skills): refine workflow migration guidance
Reduce the migration skill entry point to the decision surface agents need\nso they can select the correct resume pattern without carrying duplicate\nexamples in the initial context.\n\nClarify framework precedence so prompts that explicitly ask for\nframework-agnostic boundaries do not get Hono- or Next-specific route\nshapes, while preserving framework-specific examples when requested.\n\nCentralize canonical resume examples in the shared patterns reference to\nkeep the guidance consistent across migration paths and reduce drift.\n\nPloop-Iter: 4
* docs: add workflow deep-dive references
Add a cohesive set of deep-dive reference articles so the GA launch
has architecture-level documentation grounded in the current SDK
implementation. This gives readers verified explanations of runtime,
replay, streaming, compiler, and cost-model behavior while linking the
series together for easier navigation.

* ploop: iteration 5 checkpoint
Automated checkpoint commit.
Ploop-Iter: 5
* docs: normalize deep-dive related links
Keep the new deep-dive reference pages cross-linked so readers can move between adjacent runtime concepts without depending on older how-it-works pages alone.
This preserves navigational consistency across the GA launch docs set and reduces the chance that architectural explanations drift into isolated pages that are harder to discover and maintain.
Ploop-Iter: 2
* docs(skill): refine workflow migration routing
Tighten the migration guidance so agents choose the correct resume surface and runtime boundary earlier, reducing incorrect mixed patterns in generated migrations.
Add explicit fast paths for self-hosted targets and Step Functions task-token callbacks so the skill stays consistent on callback URL vs deterministic resume decisions.
Ploop-Iter: 6
* docs: refine workflow migration skill guidance
Clarify route selection so the migration skill composes resume, runtime, and app-boundary concerns deterministically. Add a canonical Step Functions self-hosted Hono callback recipe so migrations produce the correct callback-url pattern without mixing incompatible hook surfaces.\n\nPloop-Iter: 7
* docs: checkpoint deep-dive drafts
Preserve the verified GA launch deep-dive drafts in git so the campaign work can continue from a stable checkpoint.
Capture the reviewed documentation progress now to reduce risk of drift between source-backed research and the publishable drafts.
Ploop-Iter: 3
* docs(skills): tighten workflow migration routing
Clarify the migration skill's route-selection rules so generated guidance stays consistent across resume surfaces, runtime targets, and named framework boundaries.
This reduces ambiguous outputs where agents might mix framework syntaxes or invent callback routes for webhook-based flows, which leads to migration guidance that does not match the user's runtime model.
Ploop-Iter: 8
* docs: finalize workflow deep dives
Clarify the runtime mechanics behind the GA deep-dive series so launch content stays aligned with the implementation and existing docs. Tightening these explanations reduces the risk of readers internalizing inaccurate mental models about replay, compilation, and workflow execution.\n\nPloop-Iter: 4
* docs(skills): refine workflow migration routing
Clarify route selection so migrations choose the correct resume surface and app boundary patterns for the target runtime and framework. Strengthen verification guidance to reject invented callback routes in URL-based flows and keep examples aligned with the documented migration rules.
Ploop-Iter: 9
* docs: sync compiler deep-dive runtime details
Align the compiler deep-dive trio with the actual Workflow runtime so launch materials describe the same execution model users rely on. This keeps the GA narrative accurate around deterministic replay, step queue triggers, and runtime bundle responsibilities, reducing the risk of docs teaching an architecture the SDK does not implement.
Ploop-Iter: 5
* docs(skill): tighten workflow migration guidance
Reduce hot-path skill context so migration routing stays easier to select and
verify during activation.
Trimmed examples and converted long invalid samples into concise failure rules
so the skill points agents to on-demand references instead of loading bulky
worked code by default.
Ploop-Iter: 10
* docs: tighten workflow migration guidance
Clarify route-key planning and resume-surface defaults so migration outputs
stay deterministic when prompts underspecify callback behavior.
Strengthen the deep-dive docs to trace runtime handoffs more directly,
which reduces ambiguity about how the compiler split maps to durable
execution behavior.
Ploop-Iter: 11
* docs: refine streaming and cost deep dives
Clarify the operational model behind durable streaming and zero-cost suspension so launch materials stay source-accurate for readers comparing workflow runtimes.
The updates make the workflow-step boundary, persistence path, and queue-driven cost story more explicit, reducing ambiguity around where stream I/O is allowed and why long waits do not consume compute.

* ploop: iteration 12 checkpoint
Automated checkpoint commit.
Ploop-Iter: 12
* docs: tighten deep-dive streaming accuracy
Align the launch deep dives with the current runtime so campaign content does not misstate suspension behavior or streaming backend capabilities.
These edits clarify the distinct resume paths for step suspension versus timed waits and document the backend-specific streaming guarantees now available across local, Vercel, and Postgres worlds, reducing the risk that readers build incorrect mental models from launch materials.
Ploop-Iter: 7
* docs(skills): refine callback resume taxonomy
Clarify when migrations should use deterministic internal resume versus generated callback URLs so skill outputs stay consistent across frameworks and hosting targets. Distinguish default webhook responses from manual-response flows to prevent ambiguous guidance and keep the shared callback references directly inspectable.\n\nPloop-Iter: 13
* docs: refine deep-dive runtime wording
Clarify the runtime semantics behind suspension and durable streaming so the GA launch materials stay aligned with the source of truth.
These edits tighten descriptions around wake-up paths, backend behavior, and stream lifecycle details to reduce ambiguity for readers comparing the docs to the implementation.
Ploop-Iter: 8
* docs: clarify webhook response mode defaults
Clarify when migrations should use the default webhook behavior versus
manual responses so agents make the same callback choice across the
skill entrypoint, shared patterns, and API reference.
This reduces avoidable ambiguity for callback-url prompts and makes the
default 202 behavior explicit unless a prompt requires custom response
semantics.
Ploop-Iter: 14
* docs: align cost model wake-up semantics
Prevent the GA launch materials from teaching an incorrect mental model about how suspended runs wake back up. The updated wording keeps the blog, social, and reference variants anchored to the real runtime paths so readers understand which transitions are queue-delayed, which are step-driven re-enqueues, and why that distinction matters for the cost story.

* ploop: iteration 10 checkpoint
Automated checkpoint commit.
Ploop-Iter: 10
* docs: clarify webhook resume choices
Explain the resume-surface decision points so migration and API guidance steer authors toward the correct webhook or hook pattern for the prompt.
Reduce common callback-routing mistakes early in the docs and skill so agents make fewer wrong assumptions during workflow migrations.
Ploop-Iter: 15
* docs: tighten cost model deep dives
Clarify the cost-model narrative so launch materials make source-verifiable
claims about suspension, wake-up paths, and polling behavior.
This keeps the GA messaging aligned with the runtime's actual control
flow and avoids overclaiming where the implementation has narrower
semantics than the original copy suggested.
Ploop-Iter: 11
* docs(skills): tighten resume routing guidance
Keep the migration skill entrypoint small so agents load the routing contract only when the source actually pauses for external resume. Clarify the public webhook docs around the default callback flow to reduce accidental use of lower-level runtime APIs.\n\nPloop-Iter: 16
* docs: tighten deep-dive runtime claims
Align the launch materials with the current runtime semantics so the
cost-model and execution-model narrative stays defensible against the
actual implementation.
This keeps the GA campaign focused on claims we can support directly from
source, especially around suspension, re-enqueue behavior, and the
difference between orchestration compute and client-side polling helpers.
Ploop-Iter: 12
* docs: correct cost model deep dive claims
Align the cost-model launch content with the runtime's actual suspension and re-entry mechanics so GA messaging does not overstate identical-cost waits or imply residency that the queue-based engine does not have.
This keeps the public explanation consistent with source-backed behavior around timed wake-ups, explicit workflow re-queue after step completion, and the distinction between idle worker residency and boundary I/O.
Ploop-Iter: 13
* chore: remove non-cookbook files from cookbook branch
Remove deep-dive articles, migration guides/skill, vercel-toolbar skill,
workflow-skills test fixtures, and misc artifacts that belong in separate
branches (deep-dives, migration-guides). Revert create-webhook.mdx,
getting-started/meta.json, and code-transform.mdx to main versions.
* docs: address toolbar feedback on cookbook pages
Address Vercel toolbar comments from Nathan Rajlich, Peter Wielander, Pranay Prakash, and Karthik Kalyanaraman on the cookbook branch.
In saga.mdx, remove the unnecessary `if (!(error instanceof FatalError)) throw error;` guard in the catch block — compensations should always unwind regardless of error type. Replace the `while/pop()!()` loop with a cleaner `for...of reverse()` to avoid the non-null assertion.
In ai-sdk.mdx, split the "Using Different Providers" section into two subsections: "Vercel Gateway (string model IDs)" clarifying that all string model IDs route through Gateway, and "Direct Provider Access" showing how to import from provider packages like `@workflow/ai/openai` to bypass Gateway. Change the "Tool Functions as Steps" section to "Tool Functions with Steps" and reword to explain that tool execute functions can optionally include steps via "use step" but don't have to — when they aren't steps, they run in workflow context and can modify workflow state directly.
In sandbox.mdx, rewrite the page to reflect that `@vercel/sandbox` now has first-class Workflow SDK support. Replace all `declare function` stubs and `// TODO` placeholders with real `import { Sandbox } from "@vercel/sandbox"`. Remove the four separate "use step" wrapper functions (provisionSandbox, runCommand, teardownSandbox, saveSandboxSnapshot) and show direct `Sandbox.create()`, `sandbox.runCommand()`, and `sandbox.destroy()` calls in the workflow function since these implicitly run as steps. Simplify the agent tool example to use inline execute functions that call Sandbox methods directly with an `activeSandbox` variable for workflow state.
Across all cookbook files, replace "Workflow DevKit" with "Workflow SDK" (8 instances in 5 files: publishing-libraries.mdx, secure-credentials.mdx, ai-sdk.mdx, chat-sdk.mdx, sandbox.mdx).
* docs: simplify cookbook index to plain MDX listing
Replace the interactive CookbookExplorer (726-line decision tree + browse
component) with a simple MDX page that lists recipes grouped by category
with linked titles and descriptions. Remove v1-v5 design variations and
trim cookbook-tree.ts to sidebar-only metadata.
* fix type checks
