# Gitea PR Review

You are tasked with **addressing** PR review comments by making code changes, then summarizing what was done. This skill drives PR progress, not just conversation.

## Philosophy

**Comments are work items, not conversation starters.**

When a reviewer leaves a comment, they're identifying something that needs attention. This skill:
1. Categorizes comments by actionability
2. Makes code changes to address actionable comments
3. Commits and pushes those changes
4. Posts a single summary comment describing what was done

## Prerequisites

- `tea` CLI configured with a Gitea/Forgejo instance
- Access token from tea config: `~/.config/tea/config.yml`
- Repository must be a Gitea/Forgejo remote (not GitHub)
- **Nix users**: All tools available via nixpkgs (`nix run nixpkgs#tea`)

## Initial Setup

When this command is invoked:

1. **Parse the input for PR number**:
   - If a PR number is provided as argument, use it
   - If no PR number, detect from current branch (see PR Detection section)

2. **Verify required tools are available**:
   ```bash
   which tea
   ```

   If tea is missing:
   ```
   Error: `tea` CLI not found.

   Please install:
   - Nix: nix run nixpkgs#tea
   - Other: https://gitea.com/gitea/tea
   ```
   **STOP** if tea is missing.

3. **Extract configuration from tea config**:
   ```bash
   # Read tea config (it's YAML but simple enough to grep)
   TEA_CONFIG="$HOME/.config/tea/config.yml"
   GITEA_URL=$(grep -A1 'logins:' "$TEA_CONFIG" | grep 'url:' | head -1 | sed 's/.*url: //')
   TOKEN=$(grep -A5 'logins:' "$TEA_CONFIG" | grep 'token:' | head -1 | sed 's/.*token: //')
   ```

   If config is missing or invalid:
   ```
   Error: Could not read tea config at ~/.config/tea/config.yml

   Please ensure `tea` is installed and configured:
   1. Install tea
   2. Log in: tea login add --url https://your-gitea-instance --token YOUR_TOKEN
   ```
   **STOP** if config is invalid.

4. **Detect repository info from git remote**:
   ```bash
   REMOTE_URL=$(git remote get-url origin)
   # Parse owner and repo from URL (handles both SSH and HTTPS)
   OWNER=$(echo "$REMOTE_URL" | sed -E 's#.*[:/]([^/]+)/[^/]+\.git$#\1#')
   REPO=$(echo "$REMOTE_URL" | sed -E 's#.*/([^/]+)\.git$#\1#')
   ```

5. **Ensure we're on the PR branch**:
   ```bash
   CURRENT_BRANCH=$(git branch --show-current)
   # Verify this branch corresponds to the PR
   ```

6. **Respond with**:
   ```
   Addressing PR review comments for PR #{PR_NUMBER}...

   Repository: {OWNER}/{REPO}
   Branch: {CURRENT_BRANCH}
   Gitea URL: {GITEA_URL}
   ```

## PR Detection

If no PR number is provided, detect from the current branch:

```bash
CURRENT_BRANCH=$(git branch --show-current)
tea pr list --fields index,head --output simple | grep "$CURRENT_BRANCH"
```

If no PR exists for the current branch, use `AskUserQuestion`:

```
No PR found for branch '{CURRENT_BRANCH}'.

Would you like to:
1. Enter a PR number manually
2. Cancel
```

## Workflow

### Step 1: Fetch and Parse Comments

Fetch all reviews and their comments:

```bash
# Fetch reviews (filter out dismissed reviews)
curl -s -H "Authorization: token $TOKEN" \
  "$GITEA_URL/api/v1/repos/$OWNER/$REPO/pulls/$PR_NUMBER/reviews" \
  | jq '[.[] | select(.dismissed != true)]'

# For each review, fetch comments
curl -s -H "Authorization: token $TOKEN" \
  "$GITEA_URL/api/v1/repos/$OWNER/$REPO/pulls/$PR_NUMBER/reviews/$REVIEW_ID/comments"
```

**Filter resolved comments**: When processing comments, skip any that have been marked as resolved. Check the `resolver` field in the comment response - if it's not null, the comment has been resolved and should be skipped.

```bash
# Example: Filter to only unresolved comments
jq '[.[] | select(.resolver == null)]'
```

If no reviews found or all comments are resolved:
```
No unresolved reviews found for PR #{PR_NUMBER}.
Nothing to address.
```
**STOP** here.

### Step 2: Categorize Comments

For each comment, categorize it as one of:

| Category | Description | Action |
|----------|-------------|--------|
| **actionable** | Requests a code change, addition, or fix | Launch subagent to make change |
| **question** | Asks for clarification or explanation | Include answer in summary |
| **acknowledged** | FYI, self-resolved, or "no action needed" noted | Note in summary |
| **blocked** | Requires external input or is out of scope | Flag for user |

**Categorization heuristics**:
- Contains "add", "change", "fix", "update", "consider adding", "should be" → **actionable**
- Contains "?" or "why", "how", "what" → **question**
- Contains "no need to update", "will be separate", "acknowledged" → **acknowledged**
- Contains "discuss", "later", "out of scope", "blocked by" → **blocked**

Display the categorization:
```
## Comment Analysis

### Actionable (will make changes):
1. {file}:{line} - "{comment_summary}" → Will add nix note to prerequisites

### Questions (will answer in summary):
2. {file}:{line} - "{comment_summary}" → Explain CI token approach

### Acknowledged (no action needed):
3. {file}:{line} - "{comment_summary}" → Reviewer noted separate skill

### Blocked (needs input):
(none)
```

### Step 3: User Confirmation

Use `AskUserQuestion` to confirm the plan:

```
I've categorized {N} comments. My plan:

**Will make changes for:**
- {file}:{line}: {planned_change}

**Will explain in summary:**
- {file}:{line}: {planned_explanation}

**No action needed:**
- {file}:{line}: {reason}

Proceed with this plan?
```

Options:
1. **Proceed** - Execute the plan
2. **Modify** - Let user adjust categorization
3. **Cancel** - Exit without changes

### Step 4: Address Actionable Comments (Parallel Subagents)

For each actionable comment, launch a subagent using the Task tool:

```
Launch Task subagent with:
- subagent_type: "general-purpose"
- prompt: |
    You are addressing a PR review comment. Make the requested change and nothing else.

    **File**: {file_path}
    **Line**: {line_number}
    **Comment**: {comment_body}
    **Diff context**:
    ```
    {diff_hunk}
    ```

    Instructions:
    1. Read the file to understand context
    2. Make the minimal change to address the comment
    3. Do NOT commit - just make the edit
    4. Report what you changed

    Be precise. Only change what's needed to address this specific comment.
```

**Important**: Launch actionable comment subagents in parallel when they touch different files. For comments on the same file, run sequentially to avoid conflicts.

Wait for all subagents to complete and collect their results.

### Step 5: Commit and Push

After all subagents complete:

1. **Stage changes**:
   ```bash
   git add -A
   ```

2. **Create commit with summary**:
   ```bash
   git commit -m "Address PR review comments

   Changes made:
   - {file1}: {change_summary}
   - {file2}: {change_summary}

   Addresses comments from review by {reviewer}"
   ```

3. **Push to remote**:
   ```bash
   git push
   ```

### Step 6: Post Summary Comment

Post a single comment summarizing all actions taken:

```bash
tea comment $PR_NUMBER "$(cat <<'EOF'
## Review Comments Addressed

cc @{reviewer1} @{reviewer2}

**Changes made** (commit {SHORT_SHA}):
- `{file1}:{line}`: {what_was_changed}
- `{file2}:{line}`: {what_was_changed}

**Responses to questions**:
- `{file3}:{line}`: {answer_to_question}

**Acknowledged** (no action needed):
- `{file4}:{line}`: {reason_no_action}

---
*Automated response via /gitea_pr_review*
EOF
)"
```

### Step 7: Final Summary

Display to user:

```
## PR Review Complete

**Commit**: {SHA}
**Changes**: {N} files modified

### Actions Taken:
- [x] {file1}:{line} - Added nix prerequisite note
- [x] {file2}:{line} - Explained CI approach in comment
- [ ] {file3}:{line} - Acknowledged (separate skill)

**Reviewers tagged**: @{reviewer1}, @{reviewer2}
**Comment posted**: {comment_url}

PR URL: {GITEA_URL}/{OWNER}/{REPO}/pulls/{PR_NUMBER}
```

**Note**: When posting the summary comment, tag all reviewers who left comments so they receive notifications about the changes.

## Error Handling

### Subagent failed to make change

If a subagent fails:
```
Warning: Could not address comment on {file}:{line}

Reason: {error}

Options:
1. Skip this comment and continue
2. Retry with manual guidance
3. Abort all changes
```

### Push failed

```
Error pushing changes: {error}

Your changes are committed locally. You may need to:
1. Pull and resolve conflicts: git pull --rebase
2. Push again: git push
```

### No actionable comments

If all comments are questions/acknowledged:
```
No code changes needed.

All comments are either questions or acknowledged items.
Posting summary comment with explanations...
```

## API Reference

### Endpoints Used

| Action | Method | Endpoint |
|--------|--------|----------|
| List reviews | GET | `/api/v1/repos/{owner}/{repo}/pulls/{index}/reviews` |
| Get review comments | GET | `/api/v1/repos/{owner}/{repo}/pulls/{index}/reviews/{id}/comments` |
| Create issue comment | POST | via `tea comment` |

### Review States

- `PENDING` - Draft review not yet submitted
- `COMMENT` - General comment without approval/rejection
- `APPROVE` - Approving the changes
- `REQUEST_CHANGES` - Requesting changes before merge

## Shell Command Patterns

Claude Code's bash execution has quirks. Use these patterns for reliability:

### curl requests

**DO** - Use single quotes for URL and header separately:
```bash
curl -s 'https://git.example.com/api/v1/repos/owner/repo/pulls/1/reviews' \
  -H 'Authorization: token YOUR_TOKEN_HERE' | jq .
```

**DON'T** - Variable expansion in `-H` flag often fails:
```bash
# This may fail with "blank argument" errors
curl -s -H "Authorization: token $TOKEN" "$URL"
```

### Iterating over reviews

**DO** - Run separate commands for each review ID:
```bash
echo "=== Review 4 ===" && curl -s 'URL/reviews/4/comments' -H 'Authorization: token ...' | jq .
echo "=== Review 5 ===" && curl -s 'URL/reviews/5/comments' -H 'Authorization: token ...' | jq .
```

**DON'T** - For loops with multiline bodies often fail:
```bash
# This may cause syntax errors
for id in 4 5 6; do
  curl -s "URL/reviews/$id/comments"
done
```

### tea comment

**DO** - Use single-quoted string for comment body:
```bash
tea comment 26 '## Summary

Changes made:
- Item 1
- Item 2'
```

**DON'T** - Heredocs may hang or timeout:
```bash
# This may hang indefinitely
tea comment 26 "$(cat <<'EOF'
...
EOF
)"
```

## Limitations

1. **Thread replies**: Gitea API doesn't support inline thread replies. We post a single summary comment instead.

2. **Complex changes**: For comments requiring significant refactoring, the subagent may need guidance. The skill will flag these as "blocked" for user input.

3. **Merge conflicts**: If the branch is behind, you may need to rebase before changes can be pushed.
