### Running multiple dev instances

Set `T3CODE_DEV_INSTANCE` to any value to deterministically shift all dev ports together.

- Default ports: server `3773`, web `5173`
- Shifted ports: `base + offset` (offset is hashed from `T3CODE_DEV_INSTANCE`)
- Example: `T3CODE_DEV_INSTANCE=branch-a bun run dev:desktop`

If you want full control instead of hashing, set `T3CODE_PORT_OFFSET` to a numeric offset.

## Runtime modes

T3 Code has a global runtime mode switch in the chat toolbar:

In `@scripts/dev-runner.mjs` around lines 61 - 67, The usage string thrown in
main() is misleading because the script is invoked via "bun run"; update the
thrown Error message inside the mode validation (the block that checks mode and
MODE_ARGS) to reflect the actual invocation (e.g., include "bun run" and mention
optional flags like --dry-run) so the message matches how users run this script;
locate the error creation in function main() where MODE_ARGS is referenced and
replace the existing Usage text with the corrected invocation text.

### Running multiple dev instances

Set `T3CODE_DEV_INSTANCE` to any value to deterministically shift all dev ports together.

- Default ports: server `3773`, web `5173`
- Shifted ports: `base + offset` (offset is hashed from `T3CODE_DEV_INSTANCE`)
- Example: `T3CODE_DEV_INSTANCE=branch-a bun run dev:desktop`

If you want full control instead of hashing, set `T3CODE_PORT_OFFSET` to a numeric offset.

## Runtime modes

T3 Code has a global runtime mode switch in the chat toolbar:

### Running multiple dev instances

Set `T3CODE_DEV_INSTANCE` to any value to deterministically shift all dev ports together.

- Default ports: server `3773`, web `5173`
- Shifted ports: `base + offset` (offset is hashed from `T3CODE_DEV_INSTANCE`)
- Example: `T3CODE_DEV_INSTANCE=branch-a bun run dev:desktop`

If you want full control instead of hashing, set `T3CODE_PORT_OFFSET` to a numeric offset.

## Runtime modes

T3 Code has a global runtime mode switch in the chat toolbar:

### Running multiple dev instances

Set `T3CODE_DEV_INSTANCE` to any value to deterministically shift all dev ports together.

- Default ports: server `3773`, web `5173`
- Shifted ports: `base + offset` (offset is hashed from `T3CODE_DEV_INSTANCE`)
- Example: `T3CODE_DEV_INSTANCE=branch-a bun run dev:desktop`

If you want full control instead of hashing, set `T3CODE_PORT_OFFSET` to a numeric offset.

## Runtime modes

T3 Code has a global runtime mode switch in the chat toolbar:

numeric T3CODE_DEV_INSTANCE values aren't validated before use - large numbers like "70000" will pass through but fail port validation later with a confusing error

⚠️ Potential issue | 🟡 Minor

Align usage message with actual invocation.
The scripts call this via bun run, so the error text is slightly misleading.

✏️ Suggested tweak
- throw new Error(`Usage: bun scripts/dev-runner.mjs <mode>. Supported modes: ${supportedModes}`);+ throw new Error(`Usage: bun run scripts/dev-runner.mjs <mode>. Supported modes: ${supportedModes}`);

Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

In `@scripts/dev-runner.mjs` around lines 61 - 67, The usage string thrown in
main() is misleading because the script is invoked via "bun run"; update the
thrown Error message inside the mode validation (the block that checks mode and
MODE_ARGS) to reflect the actual invocation (e.g., include "bun run" and mention
optional flags like --dry-run) so the message matches how users run this script;
locate the error creation in function main() where MODE_ARGS is referenced and
replace the existing Usage text with the corrected invocation text.
