Readmes: React readme uses imported catalogues instead of hand-written message objects, root readme gains a React section, format/transform readmes drop trailing semicolons, Babel readme gains the catalogues example, core readme mentions the number/date/time macros.

Docs: install commands one per line, quickstart runtime example uses catalogue.locale, standalone number/date/time examples, exit codes section removed from the CLI reference, number/date/time macros added to the core and React API references, assorted stale wording fixed.

Code: Catalogue.Options removed in favour of Record<Locale, Catalogue.Source>; the id prop is allowed on , matching what the JSX transform already reads.

Skill: skills/saykit/SKILL.md, an agent skill covering setup, macros, runtime, React and Carbon, workflow and common errors, installable with npx skills add k0d13/saykit. Pinned to 0.10 and tells the agent to refresh it on a version mismatch. Blind-tested across four rounds with a fresh session that had only the skill text.

Walkthrough

The PR removes Catalogue.Options, updates createCatalogue, permits Say.id, documents standalone formatting APIs, expands React integration guidance, and aligns installation, plugin, runtime, and CLI documentation.

Changes

Catalogue and runtime contracts

Layer / File(s) Summary
Catalogue API contract
packages/integration/src/catalogue.ts, packages/integration/src/catalogue.test.ts, website/content/reference/api/saykit.mdx, website/content/core-concepts/runtime.mdx, .changeset/catalogue-options.md
createCatalogue now accepts Record<Locale, Catalogue.Source>. The Catalogue.Options type and its documentation were removed. Descriptor and subscription documentation now reflects inline messages and the current say view.
Formatting and runtime authoring
packages/integration/src/..., packages/integration-react/src/runtime/index.ts, website/content/core-concepts/messages.mdx, website/content/integrations/react.mdx, website/content/reference/api/saykit.mdx
The documentation covers say.number, say.date, say.time, standalone formatting, and the related React components. Say now accepts an optional id.
React integration flow
README.md, packages/integration-react/README.md, website/content/getting-started/quickstart.mdx, website/content/guides/locale-detection.mdx, website/content/reference/api/react.mdx
The examples now show JSX transformation, lazy locale loading, store-based locale switching, SayProvider, numbered message tags, and the React formatting components.

Documentation alignment

Layer / File(s) Summary
Documentation and example alignment
packages/*/README.md, website/content/core-concepts/*, website/content/getting-started/*, website/content/reference/cli.mdx
Documentation now uses the catalogue, view, store, and macro runtime model. Installation commands, formatter examples, plugin configuration, and CLI guidance were updated.

Priority: ⬇️ Low

Estimated code review effort: 3 (Moderate) | ~20 minutes

Change: Other

Merge Risk: 🔵 Low · up to 10921

The React setup instructions can leave users with untranslated TSX messages, and the quickstart runtime example cannot be copied as valid TypeScript without defining its inputs. Correct these examples before publishing the documentation.

Greptile Summary

This PR refreshes SayKit documentation, removes Catalogue.Options in favor of a locale-to-source record, permits id on <Say>, and adds an agent skill.

  • Updates React setup, catalogue-loading guidance, and standalone formatting examples.
  • The new skill covers setup, macros, runtime objects, framework integrations, and extraction workflows.
  • Three non-blocking corrections would improve the skill's ordinal examples, initial lazy-locale loading guidance, and server-layout typing.

Confidence Score: 5/5

The PR appears safe to merge, with non-blocking corrections recommended for three examples and instructions in the new skill.

The remaining findings concern incorrect ordinal suffixes, incomplete lazy-locale initialization guidance, and missing route-parameter typing in documentation examples; they do not change application runtime behavior in this repository. The earlier React setup findings are no longer outstanding.

Files Needing Attention: skills/saykit/SKILL.md

Prompt To Fix All With AI
### Issue 1
skills/saykit/SKILL.md:149
**Ordinal examples produce incorrect suffixes**

Numeric ordinal branches match exact values, so only 1, 2, and 3 receive the special suffixes. Numbers such as 21, 22, and 23 fall through to `other`, producing “21th”, “22th”, and “23th”. Use `one`, `two`, and `few` in both this example and the JSX `<Say.Ordinal>` example so agents copying these patterns generate correct English ordinals.

### Issue 2
skills/saykit/SKILL.md:259
**Mixed catalogues also need loading**

Initial loading is necessary whenever the selected locale is lazy, not only when every locale is lazy. With the mixed catalogue above, a French browser selects `fr`. Copying the browser initialization recipe without the separate API-demonstration calls then throws during `createStore`, before the application starts. Show `const initial = catalogue.match(navigator.languages); await catalogue.load(initial);` before `createStore(catalogue, initial)`, and extend this guidance to mixed catalogues.

### Issue 3
skills/saykit/SKILL.md:313
**Layout props omit route parameters**

`withSay` infers its locale callback's props from the component signature, but this layout declares only `children`. Consequently, `props.params` in the callback below is a TypeScript error when the example is copied. Use `LayoutProps<'/[locale]'>`, as the existing Next.js example does, or explicitly include `params: Promise<{ locale: string }>` alongside `children`.

```suggestion
function Layout({ children }: { children: React.ReactNode; params: Promise<{ locale: string }> }) {
```

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Include TSX files in the extraction bucket.

The quick-start bucket above still uses include: ['src/**/*.ts']. Adding only jsx() leaves src/app.tsx outside extraction, so its <Say> messages do not enter catalogue files. Update this instruction to also include TSX files, for example src/**/*.{ts,tsx}.

Review: skills/saykit/SKILL.md

  • Read trigger comment and gather PR context
  • Read skills/saykit/SKILL.md in full
  • Cross-check claims against actual source (packages/integration, packages/integration-react, packages/carbon, packages/config, packages/plugin-babel)
  • Verify code examples against real exported APIs
  • Post review findings

This is a well-written, dense reference doc, and it's unusually accurate — I checked 12 separate technical claims (catalogue API, store shape, say macro surface, React server/client APIs, Carbon, config shape, Babel catalogues option, CLI, custom Formatter/Transformer types) against the actual source, and 11 of 12 check out exactly, down to specific error message strings.

One real issue found:

Packages table, line 26 — misleading export surface for @saykit/react:

| `@saykit/react`         | `<Say>`, `SayProvider`, `useSay`, `withSay`, `getSay`                       | React                                                        |

This conflates three separate entry points. Per packages/integration-react's exports map:

  • @saykit/react (root) exports only Say (Say.Plural/.Ordinal/.Select/.Number/.Date/.Time).
  • SayProvider / useSay live only in @saykit/react/client.
  • getSay / setSay / createWithSay live only in @saykit/react/server.
  • There is also no export literally named withSay — only createWithSay(catalogue), which returns a function the consumer binds locally to the name withSay. The doc's own later "Server components" section (line ~299-305) gets this right by importing createWithSay and naming the result withSay itself — it's just this summary table row that's inaccurate/oversimplified.

Suggested fix for the table row:

| `@saykit/react`         | `<Say>` (root), `SayProvider`/`useSay` (`/client`), `createWithSay`/`getSay` (`/server`) | React |

Fix this →

Minor / non-blocking:

  • The version pin ("Written for SayKit 0.10") correctly matches packages/integration/package.json (0.10.0), so that's fine and doesn't need a change.
  • Everything else — createCatalogue's record shape (no more Catalogue.Options), the View/store API, <Say> props including say-tag, the Carbon integration, saykit.config.ts shape, Babel catalogues: 'inline' | 'module' semantics, CLI commands, and the custom Formatter/Transformer/Message types — all matched the current implementation exactly, including specific runtime error strings quoted in the Errors table at the bottom.

Verdict: solid addition, low risk. Only the @saykit/react table row (line 26) needs a small correction before merge; nothing else is factually wrong.

await store.set('fr'); // loads if needed; last switch wins; a failed load keeps the current view
```

A store exposes `say`, `set` and `subscribe` only; keep the catalogue for `locales`. Do not hold `const say = store.say` across a switch. When every locale is lazy, `await catalogue.load(initial)` at the top of the i18n module before building the store.
