Summary of Changes

Documentation fixes (src/content/docs/workflows/)

build/rules-of-workflows.mdx (main target of the issue):

• Fixed .append() to .push() — JavaScript arrays don't have .append() (2 occurrences)
• Fixed env.KV to this.env.KV — bindings inside WorkflowEntrypoint classes must use this.env (12 occurrences)
• Fixed duplicate const myRandom declarations — renamed to badRandom / goodRandom
• Fixed duplicate const myNewInstance declarations — renamed to badInstance / goodInstance / instance
• Fixed duplicate let instances declarations — renamed to createdInstances
• Fixed duplicate const issues declarations — renamed to badIssues / goodIssues
• Fixed Date.now to Date.now() — missing function call parentheses
• Fixed typo: "funtions" to "functions"
• Fixed typo: "ouside" to "outside"
• Added note that createBatch is idempotent (consistent with workers-api.mdx documentation)

build/sleeping-and-retrying.mdx:

• Added missing await on step.do() call in retry config example
• Fixed broken comment syntax /* Step code goes here /* to /* Step code goes here */
• Added missing closing parenthesis ) on the same line
• Fixed invalid catch(e as Error) to catch (e) — TypeScript catch clauses don't use as

build/events-and-parameters.mdx:

• Added missing await on two step.do() calls
• Fixed broken closing syntax { /* your code here */ ) to { /* your code here */ })
• Fixed let event shadowing the run() parameter — renamed to stripeEvent

build/workers-api.mdx:

• Fixed sleepUntil docs: "seconds from the Unix epoch" to "milliseconds" (consistent with Date.parse() return value and sleeping-and-retrying.mdx)
• Fixed let event shadowing the run() parameter — renamed to stripeEvent

Changelog fix

changelog/workflows/2025-04-07-workflows-ga.mdx:

• Fixed incorrect import import { Workflow, WorkflowEvent } from "cloudflare:workflows" to import { WorkflowEntrypoint, WorkflowStep, WorkflowEvent } from "cloudflare:workers" (consistent with all other docs)

Skills reference fixes (skills/cloudflare/references/workflows/)

api.md:

• Fixed waitForEvent option key from event to type (2 occurrences)
• Fixed event.params to event.payload (2 occurrences)
• Fixed NonRetryableError import from cloudflare:workers to cloudflare:workflows
• Removed fabricated retention parameter from create() (not part of the API)

patterns.md:

• Fixed waitForEvent option key from event to type (2 occurrences)
• Fixed event.params to event.payload (7 occurrences)
• Fixed Promise.race pattern to wrap in step.do() (consistent with rules-of-workflows guidance)

gotchas.md:

• Fixed Free plan concurrent instances limit from 25 to 100 (matches limits.mdx)

README.md:

• Fixed event.params to event.payload

Ambiguities for the issue author (@elithrar)

1. The fetch() Response examples in rules-of-workflows (e.g., return await fetch(...) from a step.do) return a Response object which is not serializable. These are demonstrative examples focusing on other concepts, but could mislead developers who copy them directly. Consider adding a .json() or .text() call in a follow-up.
2. The R2 .get() example near line 624 doesn't null-check the result before calling .json(). Minor, but could fail at runtime if the key doesn't exist.

Closes #28185

Great.

1. Fix

Here's a summary of what was done:

Reverted (out of scope)

• skills/cloudflare/references/workflows/README.md
• skills/cloudflare/references/workflows/api.md
• skills/cloudflare/references/workflows/gotchas.md
• skills/cloudflare/references/workflows/patterns.md

Fix 1: Reverted skill files

All 4 skill reference files have been restored to their original (pre-PR) state.

Fix 2: Variable shadowing in changelog

src/content/changelog/workflows/2025-04-07-workflows-ga.mdx:37 — The PR fixed the import line but missed that let event = await step.waitForEvent(...) shadows the run() method's event parameter. Changed to let stripeEvent for consistency with the same fix applied in events-and-parameters.mdx and workers-api.mdx.

Self-review of all remaining doc changes

Every other change from the original PR was verified correct:

• .append() -> .push() — JS arrays don't have .append()
• env.KV -> this.env.KV — bindings in WorkflowEntrypoint require this.env
• Variable renames (badRandom/goodRandom, badInstance/goodInstance, badIssues/goodIssues) — avoid duplicate const declarations
• Date.now -> Date.now() — missing function call parens
• Typo fixes ("funtions" -> "functions", "ouside" -> "outside")
• Missing await on step.do() calls
• Broken comment syntax /* ... /* -> /* ... */
• Missing closing ) fixes
• catch(e as Error) -> catch (e) — invalid TS syntax
• sleepUntil "seconds" -> "milliseconds" — consistent with Date.parse() return value
• Changelog import fix (cloudflare:workflows -> cloudflare:workers)
• createBatch idempotency note — consistent with workers-api.mdx
