DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Reference / CLI flags

--title

A Claude Code CLI flag, read out of the shipped bundle. No mined inventory carries it: everything below comes from what this site has written about it.

What it is

The whiteboard skill gained opening sketches, named boards and clearer send-permission errors, but stays switched off.

Not Anthropic's. This is the line from the earliest changelog entry here that named it, v2.1.219.

Presence across releases

The miner has never read a build containing this name. It is here because a changelog entry of ours names it, which is evidence that it existed and not evidence of which releases carried it. The inventory starts at v2.1.138 and everything older than that was never mined.

Changelog entries naming it

  1. v2.1.229Updating an existing PR no longer passes a PR number

    Updating an existing PR now relies on your branch instead of passing a PR number.

  2. v2.1.219Whiteboard skill reworked with first sketch, named boards and up-front send-permission checks, still switched off

    The whiteboard skill gained opening sketches, named boards and clearer send-permission errors, but stays switched off.

Documentation pages

A reference table page is one whose own table defines this name, and it is where the description above came from. A page that mentions it carries the name somewhere in its text and may say nothing about it at all. Every page carrying it.

Read out of the published npm bundle release by release, and out of Anthropic's own documentation as this site captured it. Nothing on this page is a description anybody here wrote about what the CLI flag does. All CLI flags.
