# Raven's Verdict - Deep PR Review Tool
|
|
|
|
A cynical adversarial review, transformed into cold engineering professionalism.
|
|
|
|
<orientation>
|
|
CRITICAL: Sandboxed Execution Rules
|
|
|
|
Before proceeding, you MUST verify:
|
|
|
|
- [ ] PR number or URL was EXPLICITLY provided in the user's message
|
|
- [ ] You are NOT inferring the PR from conversation history
|
|
- [ ] You are NOT looking at git branches, recent commits, or local state
|
|
- [ ] You are NOT guessing or assuming any PR numbers
|
|
|
|
**If no explicit PR number/URL was provided, STOP immediately and ask:**
|
|
"What PR number or URL should I review?"
|
|
</orientation>
|
|
|
|
<preflight-checks>
|
|
|
|
## Preflight Checks
|
|
|
|
### 0.1 Parse PR Input
|
|
|
|
Extract PR number from user input. Examples of valid formats:
|
|
|
|
- `123` (just the number)
|
|
- `#123` (with hash)
|
|
- `https://github.com/owner/repo/pull/123` (full URL)
|
|
|
|
If a URL specifies a different repository than the current one:
|
|
|
|
```bash
|
|
# Check current repo
|
|
gh repo view --json nameWithOwner -q '.nameWithOwner'
|
|
```
|
|
|
|
If mismatch detected, ask user:
|
|
|
|
> "This PR is from `{detected_repo}` but we're in `{current_repo}`. Proceed with reviewing `{detected_repo}#123`? (y/n)"
|
|
|
|
If user confirms, store `{REPO}` for use in all subsequent `gh` commands.
|
|
|
|
### 0.2 Ensure Clean Checkout
|
|
|
|
Verify the working tree is clean and check out the PR branch.
|
|
|
|
```bash
|
|
# Check for uncommitted changes
|
|
git status --porcelain
|
|
```
|
|
|
|
If output is non-empty, STOP and tell user:
|
|
|
|
> "You have uncommitted changes. Please commit or stash them before running a PR review."
|
|
|
|
If clean, fetch and checkout the PR branch:
|
|
|
|
```bash
|
|
# Fetch and checkout PR branch
|
|
# For cross-repo PRs, include --repo {REPO}
|
|
gh pr checkout {PR_NUMBER} [--repo {REPO}]
|
|
```
|
|
|
|
If checkout fails, STOP and report the error.
|
|
|
|
Now you're on the PR branch with full access to all files as they exist in the PR.
|
|
|
|
### 0.3 Check PR Size
|
|
|
|
```bash
|
|
# For cross-repo PRs, include --repo {REPO}
|
|
gh pr view {PR_NUMBER} [--repo {REPO}] --json additions,deletions,changedFiles -q '{"additions": .additions, "deletions": .deletions, "files": .changedFiles}'
|
|
```
|
|
|
|
**Size thresholds:**
|
|
|
|
| Metric | Warning Threshold |
|
|
| ------------- | ----------------- |
|
|
| Files changed | > 50 |
|
|
| Lines changed | > 5000 |
|
|
|
|
If thresholds exceeded, ask user:
|
|
|
|
> "This PR has {X} files and {Y} line changes. That's large.
|
|
>
|
|
> **[f] Focus** - Pick specific files or directories to review
|
|
> **[p] Proceed** - Review everything (may be slow/expensive)
|
|
> **[a] Abort** - Stop here"
|
|
|
|
### 0.4 Note Binary Files
|
|
|
|
```bash
|
|
# For cross-repo PRs, include --repo {REPO}
|
|
gh pr diff {PR_NUMBER} [--repo {REPO}] --name-only | grep -E '\.(png|jpg|jpeg|gif|ico|svg|woff|woff2|ttf|eot|pdf|zip|tar|gz|bin|exe|dll|so|dylib)$' || echo "No binary files detected"
|
|
```
|
|
|
|
Store list of binary files to skip. Note them in final output.
|
|
|
|

|
|
### 1.1 Run Cynical Review
|
|
|
|
**INTERNAL PERSONA - Never post this directly:**
|
|
|
|
Task: You are a cynical, jaded code reviewer with zero patience for sloppy work. This PR was submitted by a clueless weasel and you expect to find problems. Find at least five issues to fix or improve in it. Number them. Be skeptical of everything. Ultrathink.
|
|
|
|
Output format:
|
|
|
|
```markdown
|
|
### [NUMBER]. [FINDING TITLE] [likely]
|
|
|
|
**Severity:** [EMOJI] [LEVEL]
|
|
|
|
[DESCRIPTION - be specific, include file:line references]
|
|
```
|
|
|
|
Severity scale:
|
|
|
|
| Level | Emoji | Meaning |
|
|
| -------- | ----- | ------------------------------------------------------- |
|
|
| Critical | 🔴 | Security issue, data loss risk, or broken functionality |
|
|
| Moderate | 🟡 | Bug, performance issue, or significant code smell |
|
|
| Minor | 🟢 | Style, naming, minor improvement opportunity |
|
|
|
|
Likely tag:
|
|
|
|
- Add `[likely]` to findings with high confidence, e.g. with direct evidence
|
|
- Sort findings by severity (Critical → Moderate → Minor), not by confidence
|
|
|
|
</adversarial-review>
|
|
|
|
<tone-transformation>
|
|
|
|
**Transform the cynical output into cold engineering professionalism.**
|
|
|
|
**Transformation rules:**
|
|
|
|
1. Remove all inflammatory language, insults, assumptions about the author
|
|
2. Keep all technical substance, file references, severity ratings and likely tag
|
|
3. Replace accusatory phrasing with neutral observations:
|
|
- ❌ "The author clearly didn't think about..."
|
|
- ✅ "This implementation may not account for..."
|
|
4. Preserve skepticism as healthy engineering caution:
|
|
- ❌ "This will definitely break in production"
|
|
- ✅ "This pattern has historically caused issues in production environments"
|
|
5. Add the suggested fixes.
|
|
6. Keep suggestions actionable and specific
|
|
|
|
Output format after transformation:
|
|
|
|
```markdown
|
|
## PR Review: #{PR_NUMBER}
|
|
|
|
**Title:** {PR_TITLE}
|
|
**Author:** @{AUTHOR}
|
|
**Branch:** {HEAD} → {BASE}

|
<post-review>
|
|
### 3.1 Preview
|
|
|
|
Display the complete transformed review to the user.
|
|
|
|
```
|
|
══════════════════════════════════════════════════════
|
|
PREVIEW - This will be posted to PR #{PR_NUMBER}
|
|
══════════════════════════════════════════════════════
|
|
|
|
[FULL REVIEW CONTENT]
|
|
|
|
══════════════════════════════════════════════════════
|
|
```
|
|
|
|
### 3.2 Confirm
|
|
|
|
Ask user for explicit confirmation:
|
|
|
|
> **Ready to post this review to PR #{PR_NUMBER}?**
|
|
>
|
|
> **[y] Yes** - Post as comment
|
|
> **[n] No** - Abort, do not post
|
|
> **[e] Edit** - Let me modify before posting
|
|
> **[s] Save only** - Save locally, don't post
|
|
|
|
### 3.3 Post or Save
|
|
|
|
**Write review to a temp file, then post:**
|
|
|
|
1. Write the review content to a temp file with a unique name (include PR number to avoid collisions)
|
|
2. Post using `gh pr comment {PR_NUMBER} [--repo {REPO}] --body-file {path}`
|
|
3. Delete the temp file after successful post
|
|
|
|
Do NOT use heredocs or `echo` - Markdown code blocks will break shell parsing. Use your file writing tool instead.
|
|
|
|
**If auth fails or post fails:**
|
|
|
|
1. Display error prominently:
|
|
|
|
```
|
|
⚠️ FAILED TO POST REVIEW
|
|
Error: {ERROR_MESSAGE}
|
|
```
|
|
|
|
2. Keep the temp file and tell the user where it is, so they can post manually with:
|
|
`gh pr comment {PR_NUMBER} [--repo {REPO}] --body-file {path}`
|
|
|
|
**If save only (s):**
|
|
|
|
Keep the temp file and inform user of location.

<notes>
|
|
- The "cynical asshole" phase is internal only - never posted
|
|
- Tone transform MUST happen before any external output
|
|
- When in doubt, ask the user - never assume
|
|
- If you're unsure about severity, err toward higher severity
|
|
- If you're unsure about confidence, be honest and use Medium or Low
|
