Auto-Fix โ Cloud PR Babysitting
Hands off a submitted PR to Claude's optional cloud auto-fix. Claude watches the PR remotely โ fixing CI failures and addressing review comments โ so you can walk away and come back to a green, ready-to-merge PR.
"This happens remotely so you can fully walk away and come back to a ready-to-go PR." โ @noahzweben
Autonomous by default. When enabled via /flux:setup (autofix.enabled: true), auto-fix activates automatically after every /flux:work PR submit. No question asked โ it just runs. Can also be invoked manually on any PR.
Session Phase Tracking
On entry, set the session phase:
PLUGIN_ROOT="${DROID_PLUGIN_ROOT:-${CLAUDE_PLUGIN_ROOT:-$(git rev-parse --show-toplevel 2>/dev/null || pwd)}}"
[ ! -d "$PLUGIN_ROOT/scripts" ] && PLUGIN_ROOT=$(ls -td ~/.claude/plugins/cache/nairon-flux/flux/*/ 2>/dev/null | head -1)
FLUXCTL="${PLUGIN_ROOT}/scripts/fluxctl"
$FLUXCTL session-phase set autofix
On completion, reset:
$FLUXCTL session-phase set idle
Prerequisites
- A PR must exist (just submitted via
/flux:work, or user provides a PR URL)
- The Claude GitHub App must be installed on the repository
- Claude web or mobile access (auto-fix runs in the cloud, not locally)
How It Works
Claude's auto-fix subscribes to GitHub activity on the PR. When a check fails or a reviewer leaves a comment, Claude investigates and pushes a fix:
- Clear fixes (lint errors, type errors, test assertion mismatches): Claude fixes, pushes, and re-runs CI automatically
- Ambiguous requests (architectural comments, multi-interpretation feedback): Claude asks you before acting
- Duplicate/no-action events: Claude notes them and moves on
Review comment replies are posted using your GitHub account but labeled as coming from Claude.
When evaluating human or bot review comments, use flux-receive-review. Before posting that something is fixed, apply flux-verify-claims.
Input
Full request: $ARGUMENTS
Accepts:
- No arguments (uses the most recently submitted PR from the current branch)
- A PR URL (e.g.,
https://github.com/org/repo/pull/123)
- A PR number (e.g.,
#123 or 123)
Workflow
Step 0: Check if enabled (manual invocation only)
When invoked automatically from /flux:work Phase 5, the config is already checked before invoking this skill โ skip this step.
When invoked manually (/flux:autofix), always continue regardless of config โ the user explicitly wants auto-fix on this PR.
Step 1: Resolve the PR
If a PR URL or number was provided, use it directly.
If no arguments, detect the current branch's PR:
PR_URL=$(gh pr view --json url -q '.url' 2>/dev/null)
If no PR found:
No PR found on the current branch. Either:
- Run /flux:work to submit a PR first
- Provide a PR URL: /flux:autofix https://github.com/org/repo/pull/123
Stop here.
Step 2: Start cloud auto-fix session
Auto-fix works by spawning an independent cloud session via claude --remote. If --remote fails (Claude GitHub App not installed, auth issue, etc.), claude will return an error โ the skill logs it and continues to Reflect without blocking. This creates a new Claude session on Anthropic's infrastructure that clones the repo, subscribes to GitHub events on the PR, and runs autonomously. The local session continues to Reflect โ both run in parallel.
claude --help 2>&1 | grep -q "\-\-remote" && echo "remote supported" || echo "no remote"
If --remote is supported (standard path):
claude --remote "Watch this PR and auto-fix any CI failures or review comments. Only address NEW activity โ CI check failures and review comments posted after this point. Do not re-address bot comments (Greptile, CodeRabbit) that were already resolved in earlier commits. PR: ${PR_URL}"
Tell the user:
Auto-fix session started for: {PR_URL}
A separate Claude session is now running in the cloud. It will:
- Fix CI failures (test errors, lint issues, type errors)
- Address review comments from human reviewers
- Handle bot feedback (Greptile/CodeRabbit) if configured
- Push fixes and re-run CI
You can walk away โ the session runs independently.
Monitor it: run /tasks in the CLI, or open claude.ai/code.
If --remote is NOT supported (older CLI version or a non-Claude agent):
Auto-fix cannot run autonomously without --remote. Tell the user:
Auto-fix requires `claude --remote` which isn't available in your CLI version.
Options:
1. Update Claude: npm i -g @anthropic-ai/claude-code@latest
Then auto-fix will work automatically on next PR submit.
2. Start it manually from the web:
- Open claude.ai/code
- Paste: {PR_URL}
- Say: "Watch this PR and auto-fix any CI failures or review comments"
3. Start it from mobile:
- Open the Claude mobile app
- Say: "Watch {PR_URL} and auto-fix CI failures and review comments"
Proceeding to Reflect โ auto-fix is not running for this PR.
In this case, skip auto-fix and continue to Reflect. Do NOT block the workflow.
Step 3: Continue to Reflect
Auto-fix is non-blocking. Whether it started successfully or not, the local session continues:
- If invoked automatically from
/flux:work โ return control to the work skill, which proceeds to Reflect
- If invoked manually (
/flux:autofix) โ offer next steps:
Auto-fix is running independently. What's next?
a) /flux:reflect โ capture learnings while context is fresh
b) /flux:scope โ start new work
c) Done for now
When Auto-Fix Runs Automatically
Auto-fix fires once per epic, at the end of /flux:work Phase 5 (Ship) โ immediately after the PR is created. The PR is always created at the end of the epic (after all tasks โ epic review โ quality โ Ship). There is no earlier PR creation point in the standard Flux flow.
The claude --remote call spawns an independent cloud session. The local session continues to Reflect in parallel. Both run independently โ the cloud session watches the PR, the local session captures learnings.
How Claude Responds to PR Activity
| Event | Claude's Response |
|---|
| CI check fails (lint, types, tests) | Investigates, pushes fix if confident, explains in session |
| Review comment (clear request) | Makes the change, pushes, replies on GitHub |
| Review comment (ambiguous/architectural) | Asks you before acting |
| Duplicate event | Notes it, moves on |
| No action needed | Notes it, moves on |
Relationship to Other Flux Skills
| Skill | Relationship | Overlap? |
|---|
/flux:work | Auto-fix activates after work submits a PR (Phase 5) | None โ sequential |
/flux:gate | Gate validates staging after merge. Auto-fix gets the PR to merge-ready state before merge | None โ different lifecycle stages |
/flux:epic-review | Epic review catches code quality issues before submit. Auto-fix catches CI/review issues after submit | See deconfliction below |
/flux:impl-review | Impl review is per-task, local. Auto-fix is per-PR, remote | None โ different scope |
/flux:reflect | Reflect runs after auto-fix is enabled (they're independent) | None โ independent |
Deconfliction with Epic Review (BYORB Self-Heal) and Review Bots
Auto-fix and BYORB self-heal are mutually exclusive โ they never both run. The routing is config-driven:
If autofix.enabled: true:
- Epic-review skips BYORB entirely (even if a draft PR exists)
- After submit, auto-fix owns the full post-submit lifecycle: CI failures, human review comments, AND bot review comments (Greptile/CodeRabbit)
- This is the better path โ cloud-based, unlimited iterations, handles everything in one place
If autofix.enabled: false (or unset):
- Epic-review skips BYORB as usual (no PR exists yet in the default flow)
- After submit, Phase 5 (Ship) runs BYORB locally against the now-existing PR โ polls for bot comments, self-heals (max 2 iterations)
- This is the fallback for users without Claude web/mobile
autofix.enabled: true autofix.enabled: false

Gotchas
- Auto-fix requires the Claude GitHub App โ it won't work without it
- Auto-fix runs remotely (cloud) โ it doesn't use your local session or context window
- Review comment replies appear under your GitHub username but are labeled as from Claude
- Auto-fix is best for mechanical fixes (CI failures, clear review feedback). For architectural discussions, Claude will ask before acting
- If you're already in a Claude web session that created the PR, just click "Auto-fix" in the CI status bar instead
- Auto-fix does NOT replace epic review or adversarial review โ those catch code quality issues before submit. Auto-fix handles the post-submit lifecycle (CI, human reviews, bot comments).
- Auto-fix and BYORB self-heal are mutually exclusive. When auto-fix is enabled, BYORB is skipped entirely โ auto-fix handles bot comments post-submit. When auto-fix is disabled, BYORB runs locally after submit as a fallback (max 2 iterations, bot comments only).
- Ralph mode: auto-fix still fires automatically after PR submit when
autofix.enabled: true. Two autonomous processes run in parallel โ Ralph locally, auto-fix in the cloud. This is fine; they don't interfere.
Update Check (End of Command)
ALWAYS run at the very end of command execution:
PLUGIN_ROOT="${DROID_PLUGIN_ROOT:-${CLAUDE_PLUGIN_ROOT:-$(git rev-parse --show-toplevel 2>/dev/null || pwd)}}"
CURRENT_VERSION=$(jq -r '.version' "${PLUGIN_ROOT}/.claude-plugin/plugin.json" 2>/dev/null)
MARKETPLACE_VERSION=$(jq -r '.plugins[0].version' "${PLUGIN_ROOT}/.claude-plugin/marketplace.json" 2>/dev/null)
if [ "$CURRENT_VERSION" != "$MARKETPLACE_VERSION" ] && [ -n "$MARKETPLACE_VERSION" ]; then
echo "Update available: v${CURRENT_VERSION} โ v${MARKETPLACE_VERSION}. Run /flux:upgrade"
fi
