Chat streams flowing like rivers, connections intertwined,
With Claude and durable paths, the architecture takes flight,
A real-time multiplayer dream, documented just right! 🚀

🤖 Fix all issues with AI agents
In `@docs/ai-chat-plan.md`:
- Around line 281-290: The fenced code block showing the directory tree
(starting with the triple backticks and the line "apps/stream-server/") lacks a
language identifier; update the opening fence from ``` to a language token such
as ```text or ```bash so markdownlint MD040 is satisfied, e.g., change the
opening fence before the directory listing to include the language identifier
while leaving the directory contents unchanged.
- Around line 404-415: The fenced code block that shows the chat/ directory tree
(the block starting with "chat/ ├── page.tsx") lacks a language identifier;
update that fenced block to include a language tag such as text (e.g., change
``` to ```text) so it satisfies markdownlint MD040 while preserving the
directory tree content in docs/ai-chat-plan.md.
- Around line 381-393: The fenced code block showing the directory tree for
"screens/chat/" violates markdownlint MD040 because it lacks a language tag;
update the opening fence from ``` to a tagged fence such as ```text (or ```bash)
so the block becomes ```text and retains the same contents; target the fenced
block that begins with the tree listing (the "screens/chat/" block) in
docs/ai-chat-plan.md and add the language identifier to satisfy MD040.
- Around line 7-35: The fenced diagram block is missing a language identifier
(MD040); update the opening backticks for the ASCII diagram (the triple-backtick
block that begins before "Any Client (Web/Mobile) ...") to include a language
tag such as text (e.g., change ``` to ```text) so markdownlint MD040 is
satisfied; apply the same fix to any other fenced blocks in this file if
present.
🧹 Nitpick comments (2)
packages/mcp/src/tools/devices/create-workspace/create-workspace.ts (1)

24-24: Inconsistent description compared to other workspace tools.

This description still includes "git worktree" while the other updated tool descriptions (delete, update, switch, navigate) have removed these references entirely. Consider simplifying for consistency:

-			description: "Create one or more git worktree workspaces on a device",
+			description: "Create one or more workspaces on a device",
.env.example (1)

33-34: Align key order with dotenv-linter expectation.

dotenv-linter flags EXPO_PUBLIC_STREAMS_URL should appear before NEXT_PUBLIC_STREAMS_URL. Consider swapping to avoid lint noise.

♻️ Suggested reorder
-NEXT_PUBLIC_STREAMS_URL=http://localhost:8080
-EXPO_PUBLIC_STREAMS_URL=http://localhost:8080
+EXPO_PUBLIC_STREAMS_URL=http://localhost:8080
