[DOCS] `/resume` session picker docs omit PR URL search support

Documentation Type

Missing documentation (feature not documented)

Documentation Location

https://code.claude.com/docs/en/common-workflows

Section/Topic

Resume previous conversations and Use the session picker

Current Documentation

The docs currently say:

* claude --from-pr 123 resumes sessions linked to a specific pull request

The /resume command (or claude --resume without arguments) opens an interactive session picker with these features: | / or any printable character other than Space | Enter search mode and filter sessions |

And the CLI reference says:

--from-pr Resume sessions linked to a specific pull request. Accepts a PR number, a GitHub or GitHub Enterprise PR URL, a GitLab merge request URL, or a Bitbucket pull request URL. Sessions are linked automatically when Claude creates the pull request

What's Wrong or Missing?

The docs explain two related pieces separately: claude --from-pr can resume PR-linked sessions, and /resume has a search/filter mode. They do not document that in v2.1.122 you can paste a PR URL directly into the interactive /resume search box and Claude Code will find the session that created that PR.

That omission matters because the supported URL formats are only documented for --from-pr. A reader of the /resume picker docs would not learn that the same linked-session lookup now works interactively for GitHub, GitHub Enterprise, GitLab merge requests, and Bitbucket pull requests.

Suggested Improvement

Add a short note in the Use the session picker section near the search-mode row explaining that the /resume picker accepts pasted PR URLs and uses them to find the session that created that PR.

Suggested wording:

You can paste a pull request URL into the /resume search box to find the session that created that PR. This works for GitHub, GitHub Enterprise, GitLab merge request URLs, and Bitbucket pull request URLs.

Also cross-reference this from the --from-pr documentation so the CLI flag and interactive picker stay aligned.

Impact

Medium - Makes feature difficult to understand

Affected Pages:

| Page | Line(s) | Context |
|------|---------|---------|
| https://code.claude.com/docs/en/common-workflows | 561-569 | Documents claude --from-pr and /resume, but not PR URL lookup inside the picker |
| https://code.claude.com/docs/en/common-workflows | 617-629 | Documents the picker's search mode, but not pasting a PR URL to find the linked session |
| https://code.claude.com/docs/en/cli-reference | 66 | Documents the supported PR URL formats for --from-pr, which should be mirrored in the interactive /resume flow |

Total scope: 2 pages affected

Behavior added in changelog version v2.1.122: pasting a PR URL into the /resume search box finds the linked session that created that PR.
