--from-pr Flag for PR-Linked Session Resume / Claude Code v2.1.27

What

Resume a previous Claude Code session that was linked to a specific pull request, by PR number or URL.

Usage

claude --from-pr 123
claude --from-pr https://github.com/owner/repo/pull/123
claude --from-pr          # opens interactive picker
claude --from-pr "search" # opens picker filtered by search term

Details

Accepts a PR number, a full PR URL, or no value (opens an interactive picker)
When passed a string that is not a number/URL, it filters the picker by that search term
Works alongside existing --resume and --continue session management flags

Evidence

CLI option definition (search for "--from-pr [value]")

Strings lifted out of the shipped bundle, so the claim above can be checked against them.

Names in this entry

cli--from-pr
Open the session picker filtered to 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
cli--resume
Resume a specific session by ID or name, or show an interactive picker to choose a session. In place of an ID, you can pass the absolute path to a session's .jsonl transcript file. The picker and name search include sessions that added this directory with /add-dir. When you pass a session ID, Claude Code searches the current project directory and its git worktrees, then every other project on this machine. Before v2.1.223, the ID search covered only the current project directory and its git worktrees. Background sessions appear in the picker marked with bg
cli--continue
Load the most recent conversation in the current directory, including a background session that has finished; opening finished background sessions requires Claude Code v2.1.257 or later. Skips sessions created with claude -p or the Agent SDK, and sessions whose first prompt was /loop. claude -p --continue includes -p, SDK, and /loop sessions. Includes sessions that added this directory with /add-dir

Anthropic's note

Upstream's own release notes for v2.1.27 name something this entry names, so the two are probably about the same change. Probably: the pairing is made on a shared name rather than on the words around it.
