# Iterate on PR Until CI Passes

Continuously iterate on the current branch until all CI checks pass and review feedback is addressed.

**Requires**: GitHub CLI (`gh`) authenticated.

**Important**: All scripts must be run from the repository root directory (where `.git` is located), not from the skill directory. Use the full path to the script via `${CLAUDE_SKILL_ROOT}`.

## Bundled Scripts

### `scripts/fetch_pr_checks.py`

Fetches CI check status and extracts failure snippets from logs.

```bash
uv run ${CLAUDE_SKILL_ROOT}/scripts/fetch_pr_checks.py [--pr NUMBER]
```

Returns JSON:
```json
{
  "pr": {"number": 123, "branch": "feat/foo"},
  "summary": {"total": 5, "passed": 3, "failed": 2, "pending": 0},
  "checks": [
    {"name": "tests", "status": "fail", "log_snippet": "...", "run_id": 123},
    {"name": "lint", "status": "pass"}
  ]
}
```

### `scripts/fetch_pr_feedback.py`

Fetches and categorizes PR review feedback using the [LOGAF scale](https://develop.sentry.dev/engineering-practices/code-review/#logaf-scale).

```bash
uv run ${CLAUDE_SKILL_ROOT}/scripts/fetch_pr_feedback.py [--pr NUMBER]
```

Returns JSON with feedback categorized as:
- `high` - Must address before merge (`h:`, blocker, changes requested)
- `medium` - Should address (`m:`, standard feedback)
- `low` - Optional (`l:`, nit, style, suggestion)
- `bot` - Automated comments (Codecov, Sentry, etc.)
- `resolved` - Already resolved threads

## Workflow

### 1. Identify PR

```bash
gh pr view --json number,url,headRefName
```

Stop if no PR exists for the current branch.

### 2. Check CI Status

Run `${CLAUDE_SKILL_ROOT}/scripts/fetch_pr_checks.py` to get structured failure data.

**Wait if pending:** If bot-related checks (sentry, codecov, cursor, bugbot, seer) are still running, wait before proceeding—they may post additional feedback.

### 3. Fix CI Failures

For each failure in the script output:
1. Read the `log_snippet` to understand the failure
2. Read the relevant code before making changes
3. Fix the issue with minimal, targeted changes

Do NOT assume what failed based on check name alone—always read the logs.

### 4. Gather Review Feedback

Run `${CLAUDE_SKILL_ROOT}/scripts/fetch_pr_feedback.py` to get categorized feedback.

### 5. Handle Feedback by LOGAF Priority

**Auto-fix (no prompt):**
- `high` - must address (blockers, security, changes requested)
- `medium` - should address (standard feedback)

**Prompt user for selection:**
- `low` - present numbered list and ask which to address:

```
Found 3 low-priority suggestions:
1. [l] "Consider renaming this variable" - @reviewer in api.py:42
2. [nit] "Could use a list comprehension" - @reviewer in utils.py:18
3. [style] "Add a docstring" - @reviewer in models.py:55

Which would you like to address? (e.g., "1,3" or "all" or "none")
```

**Skip silently:**
- `resolved` threads
- `bot` comments (informational only)

### 6. Commit and Push

```bash
git add <files>
git commit -m "fix: <descriptive message>"
git push
```

### 7. Wait for CI

```bash
gh pr checks --watch --interval 30
```

### 8. Repeat

Return to step 2 if CI failed or new feedback appeared.

## Exit Conditions

**Success:** All checks pass, no unaddressed high/medium feedback, user has decided on low-priority items.

**Ask for help:** Same failure after 3 attempts, feedback needs clarification, infrastructure issues.

**Stop:** No PR exists, branch needs rebase.

## Fallback

If scripts fail, use `gh` CLI directly:
- `gh pr checks --json name,state,bucket,link`
- `gh run view <run-id> --log-failed`
- `gh api repos/{owner}/{repo}/pulls/{number}/comments`
