Claude stands back from pull requests handled by PR Steward

What

PR Steward is described as a Claude agent that can watch a GitHub pull request (PR), fix its automated checks (CI) and merge it. Behind a flag, tengu_federated_flask, Claude Code now avoids working on PRs that Steward is handling. A PR is under Steward when it carries the label claude-pr-steward-watching or claude-pr-steward-is-working.

• /autofix-pr, which starts a cloud session to fix a PR, now also reads the PR's labels through gh pr view. If a Steward label is present, it refuses to take the PR on and explains the options: leave it with Steward, make one change and hand back, or take over by removing the label.
• /autofix-pr gives the same answer when the server responds pr_steward_owns_binding. In that case, a cloud session that was just started is archived.
• The periodic check inside an autofix session is told not to fix or push while those labels are present. Cloud autofix sessions also get extra instructions added to their first message.
• A new PR Steward section is added to the /loop skill prompt, to the PR-monitoring prompt ('You're monitoring PR #...') and to one other prompt. It tells Claude to check a PR's labels before pushing to it or watching it. If a Steward label is present, Claude must not push or start a loop, and must offer the same three choices.
• In cloud sessions, Claude is told never to remove the label itself.

This site's flag readings for tengu_federated_flask were off for its own account and for the anonymous baseline. None of them were taken under this release.

Why

Two agents pushing to one PR race each other. This keeps Claude and PR Steward from both making changes to the same pull request and leaves the choice of who handles it to you.
