  • Add Access-Control-Allow-Methods header and typed catch-error narrowing preview
  • Fix import_map path (dropped extra supabase/ prefix) preview
  • Add catch-error narrowing before reading .message preview
  • Update inaccurate "zero cold starts" claim to "fast cold starts" preview
  • Fix missing closing quote (syntax error) and corrected entrypoint path example preview
  • Fix wall clock (150s Free/400s paid) and CPU time (2s/request) limits preview
  • Fix inaccurate "60 seconds" with the 150s request idle timeout preview
  • Fix env var name EXECUTION_ID → SB_EXECUTION_ID preview
  • Fix "60-second execution limit" with the 150s idle timeout / 504 behavior preview
  • Fix wall clock (150s Free/400s paid) and CPU time (2s/request) limits preview
  • Fix bundle size limits (20MB CLI/5MB server-side) and remove nonexistent supabase update command preview

Summary by CodeRabbit

  • Documentation
    • Updated Edge Function guidance for current memory, timeout, CPU, wall-clock, and bundle-size limits.
    • Corrected configuration paths, import-map examples, CLI upgrade instructions, and execution identifier usage.
    • Improved webhook signature verification and error-handling examples, including safer handling of unexpected errors.
    • Expanded CORS examples to support additional HTTP methods and non-standard thrown values.
    • Clarified cold-start behavior in the MCP server guide.

* docs: improve write-the-docs skill and retire docs-content (supabase#49089)

## I have read the CONTRIBUTING.md file.

YES

## What kind of change does this PR introduce?

Improves the `write-the-docs` skill and retires the overlapping
`docs-content` skill (provided @czenko agrees to the latter).

## What is the current behavior?

- Docs drafts could leak future-tense / internal roadmap language, add
redundant verbiage, and add single-item lists.
- No explicit CONTRIBUTING.md / WORD_LIST.md compliance pass for docs
drafts.
- Product intent was assumed to come from Linear without a good path
path for open-source contributors.
- `docs-content` overlapped `write-the-docs` and the broader
`*-the-docs` skill set (e.g. I started
[supabase#49432](supabase#49432) before
realizing we should likely not have overlapping skills).

## What is the new behavior?

- Codifies draft pitfalls as principles in
`reference/common-pitfalls.md` (timelessness, strip internal business
context, redundancy, single-item lists), with style detail pointed from
`SKILL.md` rather than duplicated.
- Clarifies SoT: Linear + code inspection for content accuracy;
CONTRIBUTING.md / WORD_LIST.md (and future DOCS-1177 style guide) for
voice/terminology/formatting only. `common-pitfalls.md` is flagged to
fold into that guide later.
- Linear is internal and preferred when available, not required for
open-source. Missing product intent: stop Draft and hand off to
`pm-the-docs` (Frame) / `ask-the-docs` (Shape/IA); do not invent
positioning or run Frame/Shape inside this skill.
- Adds drafting mechanics notes, a compliance checklist before handoff,
and a local `/review-the-docs` self-review step.
- Removes `.claude/skills/docs-content/`; `.claude/CLAUDE.md` points at
the canonical docs skills. Supersedes supabase#49432.

## Additional context

Based on @czenko review feedback on supabase#49020 and feedback I received for
`docs-content` from @aantti while trialing the "Write the docs" process
with contributors, plus my own testing while drafting docs for product
managers.

### Test plan

- [ ] `SKILL.md` reads as Draft-only; Frame/Shape stay with
`pm-the-docs` / `ask-the-docs`
- [ ] No-Linear path: ask for Linear (internal) or hand off Frame/Shape;
no invented positioning
- [ ] `.claude/skills/docs-content/` gone; `.claude/CLAUDE.md` updated
- [ ] `.claude/skills/write-the-docs` symlink still resolves to
`.agents/skills/write-the-docs`
- [ ] Next `/write-the-docs` run: compliance re-read + pitfalls guidance
before handoff

## Summary by CodeRabbit

- **Documentation**
- Added an `edit-the-docs` workflow for restructuring and improving
existing documentation pages.
- Expanded authoring guidance for concise, timeless, user-focused
content grounded in product intent.
- Added references covering common writing pitfalls, link and anchor
conventions, and validation workflows.
- Clarified that style guidance applies to voice, formatting, and
terminology—not product behavior.
- Updated documentation workflows to distinguish planning, writing,
editing, review, and assistance responsibilities.
- Replaced the previous standalone docs-content skill with the updated
authoring skill model.

* Add blog post: Are Supabase docs agent-friendly? (supabase#49800)

## I have read the
[CONTRIBUTING.md](https://github.com/supabase/supabase/blob/master/CONTRIBUTING.md)
file.

YES

## What kind of change does this PR introduce?

Adds a new `apps/www` blog post, "Are Supabase docs agent-friendly? We
didn't know, so we checked," backdated to 2026-08-01 so it slots in
chronologically between the existing 2026-07-31 Evals launch post and
the 2026-08-05 post. The post writes up an eval-driven audit of the Row
Level Security guide built on `supabase/evals`: the first eval run found
the guide let agents grant the `anon` role write access to everything by
default, and the fix that stuck was structural, moving test guidance
next to the exact policy code a reader (human or agent) would copy.

## What is the current behavior?

No blog post exists yet for this project. Miranda Limonczenko and Nik
Richers also don't have author entries in `apps/www/lib/authors.json`.

## What is the new behavior?

- New post at
`apps/www/_blog/2026-08-01-are-supabase-docs-agent-friendly.mdx`
- New author entries for `miranda_limonczenko` and `nik_richers` in
`apps/www/lib/authors.json`
- Demo video embedded via YouTube (`youtube-nocookie.com/embed`),
matching the pattern used by other recent posts
- New image assets under
`apps/www/public/images/blog/are-supabase-docs-agent-friendly/`: the
eval pass/fail chart (`eval-chart.png`) and the `og.png`/`thumb.png`
hero images (cropped/resized to the standard 2400x1260 format)

Check the preview: [Are Supabase docs agent-friendly? We didn't know, so
we
checked](https://zone-www-dot-com-git-nikrichers-blog-agent-frie-514f83-supabase.vercel.app/blog/are-supabase-docs-agent-friendly)

## Remaining work before merge

- [x] Marketing +1 review per the Blog Post Process (post in
`#team-marketing`)

## Additional context

- Branch created directly off `origin/master` (no Linear ticket
associated; this is blog content, not a docs bug/feature).
- Content is adapted from an internal Notion writeup, tightened for blog
voice; internal Notion discussion-thread markup and an internal Linear
project link were stripped since they aren't accessible to public
readers.

### Test plan

- [ ] `pnpm run dev:www` and confirm
`/blog/are-supabase-docs-agent-friendly` renders: title, description,
both author bylines/positions, backdated date, chart image, video embed,
og:image meta tag
- [ ] Confirm `/blog` index card shows the new post with the thumb image
- [ ] Confirm `/blog/authors/miranda_limonczenko` and
`/blog/authors/nik_richers` render

Verified locally (2026-09-01): all of the above pass.

* chore(studio): refine Explorer query UI (supabase#49895)

## I have read the
[CONTRIBUTING.md](https://github.com/supabase/supabase/blob/master/CONTRIBUTING.md)
file.

YES

## What kind of change does this PR introduce?

UI refinements for Explorer query surfaces.

## What is the current behavior?

- The assistant chat textarea uses a tighter radius than the Run SQL /
Create a notebook cards on Explorer home.
- Chart results sit unevenly in the results pane because axis gutters
stack on card padding, and long Y labels can clip.
- Selecting SQL in the editor changes the primary Run button to Run
selected, which is easy to trigger by accident.
- The Prettify SQL icon in notebook query cells uses Lucide's default
size, so it doesn't match other toolbar actions.

## What is the new behavior?

- Assistant chat form uses `rounded-lg` so it matches the home action
cards everywhere the form is used.
- Query result charts collapse unused axis space, add a little padding
when labels are on, and size the Y axis from formatted ticks so longer
labels fit.
- Run is a default split button that always executes the full query. Run
selected is a secondary menu item, disabled until SQL is selected.
- Notebook cell Prettify SQL icons use `size={16}` and `strokeWidth={2}`
like the rest of the Explorer toolbar.

## Additional context

Cmd+Enter in the editor still runs the current selection when there is
one.

## Test plan

- [ ] Open Explorer home and confirm the assistant chat radius matches
the Run SQL and Create a notebook cards.
- [ ] Run a query, switch to chart view, and check spacing with labels
off and on, including large Y values.
- [ ] With no selection, click Run and confirm the full query runs. Open
the split menu and confirm Run selected is disabled.
- [ ] Select SQL, click Run, and confirm the full query still runs. Use
Run selected from the menu to run only the selection.
- [ ] In a notebook query cell, confirm Prettify SQL matches the size
and stroke of nearby toolbar icons.


Made with [Cursor](https://cursor.com)

<!-- This is an auto-generated comment: release notes by coderabbit.ai
-->

## Summary by CodeRabbit

- **New Features**
- Added a split Run control in the query editor, with separate actions
for running all content or only selected text.
  - Added support for customizing chart X-axis display settings.
- Improved chart Y-axis sizing, scaling, and tick formatting for clearer
results.

- **Bug Fixes**
  - The “Run selected” action is unavailable when no text is selected.

- **Style**
- Updated toolbar icon sizing and added rounded corners to the assistant
chat input.

* refactor(studio): simplify pipeline advanced settings (supabase#49841)

## What kind of change does this PR introduce?

Small Studio UI refactor.

## What is the current behavior?

BigQuery-only fields are already conditionally rendered, but repeat that
scope in badges. Number inputs also convert non-empty invalid values
directly with Number().

## What is the new behavior?

Removes the redundant badges, keeps number fields empty instead of
storing NaN, and gives the invalidated-slot menu consistent viewport
collision spacing.

## To test

1. Open the pipeline creation sheet and expand Advanced settings.
2. Confirm connection pool size and maximum staleness appear only for
BigQuery, without BigQuery-only badges.
3. Clear and re-enter the numeric advanced settings.
4. Open Invalidated slot behavior near the viewport edge and confirm the
menu remains visible.

<!-- This is an auto-generated comment: release notes by coderabbit.ai
-->

## Summary by CodeRabbit

* **Bug Fixes**
* Improved handling of numeric input in advanced replication settings,
including empty and invalid values.
  * Adjusted the invalidated slot menu positioning for better display.

* **UI Improvements**
* Simplified labels for connection pool size and maximum staleness
settings.

* fix(ui): standardise nav logout label to "Sign out" (supabase#49874)

## What kind of change does this PR introduce?

Copy fix across nav dropdowns.

## What is the current behavior?

Authenticated nav dropdowns use mixed logout wording: Studio shows "Log
out", while www, docs, and learn show "Logout". Studio error flows
already use "Sign out".

## What is the new behavior?

All four nav dropdowns use **Sign out**, matching the Sign in / Sign up
standard and the direction in
[DOCS-1328](https://linear.app/supabase/issue/DOCS-1328).

Related: [Slack
thread](https://supabase.slack.com/archives/C0429V78ACX/p1787081498302919)

## To test

Only Studio is possible to test (before merge) given how authentication
works across apps on staging:

1. **Studio** (`/dashboard`): open the account avatar dropdown. Confirm
the bottom item reads **Sign out**.
2. **www** (`supabase.com`): open the account avatar dropdown. Confirm
**Sign out**.
3. **docs** (`supabase.com/docs`): open the account avatar dropdown.
Confirm **Sign out**.
4. **learn** (`supabase.com/learn`): open the account avatar dropdown.
Confirm **Sign out**.

* fix: improve `useRefreshOnOpen` hook (supabase#49886)

## Problem
The `useRefreshOnOpen` returns a new object each time it runs, making
the `useCallback` useless.

## Solution
Wrap the function content in `useMemo` instead

<!-- This is an auto-generated comment: release notes by coderabbit.ai

## Summary by CodeRabbit

* **Refactor**
* Improved refresh handling for the replication destination form when it
is opened.
  * Existing refresh behavior remains consistent and reliable.
* No user-visible changes to functionality, controls, or configuration
options.

* fix(www): prevent State of Startups banner collision (supabase#49932)

## What kind of change does this PR introduce?

Bug fix.

## What is the current behavior?

The Supabase Select 2026 announcement is rendered outside the fixed
navigation stack on `/state-of-startups`, so the navigation overlaps the
banner. At shorter viewport heights, the hero's viewport-based minimum
height also lets its headline sit beneath the fixed banner and
navigation.

## What is the new behavior?

On State of Startups routes, the announcement is rendered inside the
fixed navigation stack. The hero content also reserves the stack's
responsive height as its minimum top inset, keeping the headline clear
when the viewport is short without shifting it at normal heights.
Dismissing the banner moves the navigation back to the top without a
hard-coded navigation offset. Other routes keep the existing
announcement and sticky navigation layout.

## To test

1. Open `/state-of-startups` on the deploy preview with the Supabase
Select 2026 announcement visible.
2. Confirm the announcement sits above the navigation without overlap at
desktop and mobile widths.
3. Reduce the viewport height to around 500px and confirm the State of
Startups headline remains below the navigation.
4. Dismiss the announcement and confirm the navigation moves to the top
of the viewport without leaving a gap.
5. Open another www route and confirm the announcement remains above the
sticky navigation.

## Summary by CodeRabbit

* **Bug Fixes**
* Updated the announcement banner placement on State of Startups pages
so it appears within the sticky navigation area.
  * Preserved the existing announcement banner placement on other pages.
* Increased top spacing above the State of Startups header content
across mobile and desktop layouts.

* fix(ui-patterns): prevent duplicate horizontal scrollbar in MultipleCodeBlock (supabase#49940)

## I have read the
[CONTRIBUTING.md](https://github.com/supabase/supabase/blob/master/CONTRIBUTING.md)
file.

YES

## What kind of change does this PR introduce?

Bug fix

## What is the current behavior?

Fixes supabase#49903

In `ConnectSheet` (e.g., Next.js -> Step 2 "Add files"), multi-file
instructions render using `MultipleCodeBlock`.
The `TabsContent` container in
`packages/ui-patterns/src/MultipleCodeBlock/index.tsx` was styled with
`className="... overflow-scroll ..."`.
The CSS property `overflow-scroll` forces both horizontal and vertical
scrollbar tracks to be rendered regardless of whether horizontal content
overflows.
Because the child `<CodeBlock>` already manages its own horizontal
overflow (`overflow-auto`) and fills the container width, `TabsContent`
displayed a frozen/disabled horizontal scrollbar at the top level. When
scrolling down vertically to the bottom of the code snippet,
`<CodeBlock>`'s real horizontal scrollbar came into view, resulting in
inconsistent and duplicate scrollbars.

## What is the new behavior?

- Replaced `overflow-scroll` with `overflow-y-auto` on `TabsContent` in
`MultipleCodeBlock`.
- `TabsContent` cleanly scrolls vertically when content height exceeds
`max-h-72`.
- Eliminates the duplicate/disabled top-level horizontal scrollbar.
- Horizontal code scrolling is cleanly delegated to `<CodeBlock>` only
when lines exceed the available width.
- Added a unit test in
`packages/ui-patterns/src/MultipleCodeBlock/index.test.tsx` verifying
`TabsContent` applies `overflow-y-auto` rather than `overflow-scroll`.

## Additional context

Verified locally:
- `vitest run src/MultipleCodeBlock/index.test.tsx` (all tests passing)
- `tsc --noEmit` in `packages/ui-patterns` (0 type errors)
- `prettier --check` against modified files (passed)

## Summary by CodeRabbit

* **Bug Fixes**
  * Improved code block scrolling to use vertical scrolling only.
* Prevented unnecessary horizontal scrollbars in multi-file code
examples.
  * Added coverage to verify the updated scrolling behavior.

* docs(self-hosted): reorganize the left nav items (supabase#49917)

* feat(studio): show health advisors on the project home (supabase#49661)

## I have read the
[CONTRIBUTING.md](https://github.com/supabase/supabase/blob/master/CONTRIBUTING.md)
file.

YES

## What kind of change does this PR introduce?

Feature

## Summary

- Add a `useProjectHealthLintsQuery` that runs the live health checks
(database down, unreachable, connection limit, service error rate,
infrastructure alerts)
- Surface those results on the project home advisor row alongside
security and performance errors
- Register health lint metadata (titles, docs links, entity icon) so
homepage cards can render them

Bottom of the stack. The advisor sidebar still uses tabs; health items
show under All until supabase#49662.

## To test

1. Open any project home in Studio.
2. Find the Advisor row (the cards under “Advisor found N issues”).
3. If the project has a real health problem, you should see a **HEALTH**
card (for example “Database process is down” or “Database connection
limit reached”), not only SECURITY / PERFORMANCE.
4. If the project is healthy, you should **not** see a HEALTH card.
Existing security and performance cards should still appear as before.
5. Click a HEALTH card (or any advisor card). Advisor Center should open
on that item.
6. In Advisor Center on this PR, health items only show under the
**All** tab — Health is not its own tab yet.

<!-- This is an auto-generated comment: release notes by coderabbit.ai

## Summary by CodeRabbit

- **New Features**
- Added a Health category to Advisor, with a dedicated tab and activity
icon.
- Added health checks for database availability, connection limits,
service errors, and infrastructure alerts.
- Health issues now appear alongside security and performance
recommendations with relevant troubleshooting links.

- **Bug Fixes**
- Health-related advisor findings are now correctly categorized and
displayed.

- **Tests**
- Added coverage for health checks, categorization, filtering, and
project health query behavior.

* feat(studio): add health category to the advisor panel (supabase#49662)

## I have read the
[CONTRIBUTING.md](https://github.com/supabase/supabase/blob/master/CONTRIBUTING.md)
file.

YES

## What kind of change does this PR introduce?

Feature

## Summary

- Replace advisor panel tabs with multi-select category filters,
including Health
- Load health lints in the advisor panel (without blocking other
categories on the slower health request)
- Rename item `tab` to `category` and add empty-state copy for health

Stacked on supabase#49661.

## To test

1. Open any project in Studio.
2. Open Advisor Center from the toolbar (the advisor / lightbulb
control).
3. Confirm the old All / Security / Performance / Messages **tabs are
gone**. You should see **Category**, **Status**, and **Severity**
filters instead.
4. Open Category and confirm **Health** is in the list with Security,
Performance, and Messages.
5. Select only **Health**:
- If the project is healthy: empty state “No health issues detected” /
“Your database, instance and services are all responding normally”.
   - If it is not: only health issues in the list.
6. Clear Health, then filter **Security** and **Performance**
separately. Those lists should still match what you expect from before.
7. With Health selected, also filter Severity to **Info** only. If
nothing matches, you should get “No items found” and a way to clear
filters — not a false “no health issues” message.
8. From project home, click an advisor card. Advisor Center should still
open on that same item.

## Summary by CodeRabbit

- **New Features**
- Added category-based filtering for Advisor recommendations, including
Security, Performance, Health, and Messages.
- Added Health issue recommendations and category-specific icons,
labels, and empty-state messaging.
  - Advisor results now load according to the selected categories.
- Added clearer project requirements and hidden-item controls for
filtered results.

- **Bug Fixes**
  - Invalid category and severity filter values are safely ignored.
- Improved categorization and telemetry for Advisor items, including
health and security recommendations.
