Dinesh vs Gilfoyle Code Review

Two-agent adversarial code review inspired by HBO's Silicon Valley. Gilfoyle attacks the code with withering technical precision. Dinesh defends it with flustered competence. The banter entertains; the back-and-forth produces genuinely better reviews.

Invocation

• /dg — review git diff (staged + unstaged)
• /dg 3 — git diff, max 3 rounds
• /dg src/auth.ts — review specific file
• /dg src/auth.ts 3 — specific file, 3 rounds max

Parse Arguments

1. No args → target = git diff, cap = 5
2. Number only → target = git diff, cap = that number
3. Path only → target = that path, cap = 5
4. Path + number → target = path, cap = number

Orchestration

Step 1: Gather Code

If git diff:

git diff HEAD
git diff --staged

Combine both diffs. If both are empty, tell the user there's nothing to review.

If file/path: Read the target file(s). If path is a directory, read all source files in it.

Always: Gather dependency context. Look for dependency files in the project root and include them in the context sent to agents:

• package.json, package-lock.json, yarn.lock, pnpm-lock.yaml (Node.js)
• requirements.txt, pyproject.toml, Pipfile.lock (Python)
• go.mod, go.sum (Go)
• pom.xml, build.gradle (Java)
• Gemfile, Gemfile.lock (Ruby)
• Cargo.toml, Cargo.lock (Rust)
• composer.json, composer.lock (PHP)

These are needed for Gilfoyle's dependency vulnerability scan.

Step 2: Run the Debate

Initialize: round = 0, debate_history = []

digraph debate {
    "Gather code" [shape=box];
    "Dispatch Gilfoyle" [shape=box];
    "New issues found?" [shape=diamond];
    "Dispatch Dinesh" [shape=box];
    "All conceded, no pushback?" [shape=diamond];
    "Round >= cap?" [shape=diamond];
    "Ask user: continue?" [shape=diamond];
    "Synthesize final review" [shape=doublecircle];

    "Gather code" -> "Dispatch Gilfoyle";
    "Dispatch Gilfoyle" -> "New issues found?";
    "New issues found?" -> "Synthesize final review" [label="no — converged"];
    "New issues found?" -> "Dispatch Dinesh" [label="yes"];
    "Dispatch Dinesh" -> "All conceded, no pushback?";
    "All conceded, no pushback?" -> "Synthesize final review" [label="yes — converged"];
    "All conceded, no pushback?" -> "Round >= cap?";
    "Round >= cap?" -> "Dispatch Gilfoyle" [label="no — next round"];
    "Round >= cap?" -> "Ask user: continue?" [label="yes"];
    "Ask user: continue?" -> "Dispatch Gilfoyle" [label="yes — extend cap"];
    "Ask user: continue?" -> "Synthesize final review" [label="no"];
}

Each round:

1. Dispatch Gilfoyle agent (Agent tool, general-purpose) with:

- Full content of gilfoyle-agent.md from this skill's directory - The code under review - Full debate history - Round number - Instruction: "You are doing research only — read the code and produce your review. Do NOT edit any files."

1. Display Gilfoyle's banter to the user.
2. Check convergence: Parse Gilfoyle's FINDINGS section. If all findings are repeats from previous rounds → converge.
3. Dispatch Dinesh agent (Agent tool, general-purpose) with:

- Full content of dinesh-agent.md from this skill's directory - The code under review - Gilfoyle's latest full response - Full debate history - Round number - Instruction: "You are doing research only — read the code and produce your defense. Do NOT edit any files."

1. Display Dinesh's banter to the user.
2. Check convergence: Parse Dinesh's FINDINGS section. If every point is [concede] with zero [defend] or [dismiss] → converge.
3. Append both responses to debate_history, increment round.
4. If round >= cap: Ask user: *"These two could go all night. Continue for more rounds? (y/N)"*

- Yes → extend cap by original amount, continue loop - No → proceed to synthesis

Convergence announcements (pick one that fits):

• "Gilfoyle has run out of things to hate. Unprecedented."
• "Dinesh has conceded defeat. As expected."
• "These two are going in circles. Separating them before it gets physical."

Step 3: Synthesize Final Review

After the debate ends, produce a structured summary from the full debate transcript.

Display format:

## Dinesh vs Gilfoyle Review — [target]
### [N] rounds of mass destruction

---
### Best of the Banter
[2-4 of the funniest or most insightful exchanges from the debate]

---

### Verdict

#### Critical (Gilfoyle won, Dinesh conceded)
[Issues where Dinesh couldn't mount a defense — these are real and need fixing]
- `file:line` — issue — fix

#### Important (Gilfoyle won after debate)
[Issues Dinesh tried to defend but Gilfoyle's argument was stronger]
- `file:line` — issue — fix

#### Contested (Dinesh held his ground)
[Issues where Dinesh's defense was valid — code is likely fine]
- `file:line` — what was raised — why the defense holds

#### Dismissed (Gilfoyle was nitpicking)
[Issues both sides agree don't matter]
- `file:line` — what was raised — why it's a non-issue

### Strengths
[Things even Gilfoyle grudgingly acknowledged were good]

### Score
Gilfoyle: X | Dinesh: Y
[Tongue-in-cheek tally of who won more arguments]

### Recommended Changes
[Clean checklist — no banter, no context, just what to do]
- [ ] `file:line` — what to change
- [ ] `file:line` — what to change
- [ ] ...

If no changes needed: "Nothing to fix. Gilfoyle is furious."

Step 4: Offer Comic Strip

After displaying the final review, ask the user:

*"Want a comic strip of the best moments? (y/N/pr)"* - y — generate and open in browser - pr — generate, convert to PNG, and attach to the current PR as a comment - N — skip

If y or pr, generate an HTML comic strip:

1. Read the comic template from comic-template.html in this skill's directory.
2. Fill in the template placeholders:

- {{REVIEW_TARGET}} — the target reviewed (e.g., "UI Codebase", "git diff", file path) - {{ROUND_COUNT}} — number of debate rounds - {{GILFOYLE_SCORE}} / {{DINESH_SCORE}} — final scores - {{DATE}} — current date - {{PANELS}} — Generate 4-8 comic panels from the best banter exchanges. Each panel uses this HTML structure:

<!-- Gilfoyle panel -->
<div class="panel gilfoyle">
  <span class="panel-number">1</span>
  <div class="panel-header">
    <div class="avatar"><svg><use href="#gilfoyle-avatar"/></svg></div>
    GILFOYLE
  </div>
  <div class="panel-body">
    <div class="speech">The quote goes here. Use <code>inline code</code> for technical references.</div>
  </div>
</div>

<!-- Dinesh panel -->
<div class="panel dinesh">
  <span class="panel-number">2</span>
  <div class="panel-header">
    <div class="avatar"><svg><use href="#dinesh-avatar"/></svg></div>
    DINESH
  </div>
  <div class="panel-body">
    <div class="speech">The response goes here.</div>
  </div>
</div>

<!-- Full-width panel for dramatic moments -->
<div class="panel gilfoyle full-width">
  <span class="panel-number">3</span>
  <div class="panel-header">
    <div class="avatar"><svg><use href="#gilfoyle-avatar"/></svg></div>
    GILFOYLE
  </div>
  <div class="panel-body">
    <div class="speech">A particularly devastating line that deserves the full width.</div>
  </div>
</div>

• {{VERDICT_ITEMS}} — Generate verdict items from the final review:

<div class="verdict-item">
  <span class="tag tag-fixed">FIXED</span> CSP nonce replaced with deploy-time placeholder
</div>
<div class="verdict-item">
  <span class="tag tag-contested">CONTESTED</span> MutationObserver lifetime — Dinesh held ground
</div>
<div class="verdict-item">
  <span class="tag tag-dismissed">DISMISSED</span> prop-types — tree-shakes out
</div>

1. Select the best moments for panels. Prioritize:

- The funniest exchanges (back-and-forth pairs work best) - Moments where Gilfoyle conceded (rare, dramatic) - Dinesh's best zingers - The most technically devastating lines - Keep quotes concise — trim to 1-3 sentences per speech bubble

1. Write the filled HTML to a timestamped file: /tmp/dg-comic-{timestamp}.html

If y: 5. Open it in the browser: open /tmp/dg-comic-{timestamp}.html 6. Tell the user where the file is saved.

If pr: 5. Convert to PNG using a headless browser:

# Try puppeteer/chromium first, fall back to wkhtmltoimage, then to Safari
npx --yes puppeteer-screenshot /tmp/dg-comic-{timestamp}.html /tmp/dg-comic-{timestamp}.png 2>/dev/null \
  || wkhtmltoimage --quality 90 /tmp/dg-comic-{timestamp}.html /tmp/dg-comic-{timestamp}.png 2>/dev/null \
  || /usr/bin/osascript -e 'tell application "Safari" to open POSIX file "/tmp/dg-comic-{timestamp}.html"'

If screenshot tools aren't available, tell the user to screenshot manually from the browser. 6. Detect the current PR:

gh pr view --json number,url --jq '.number'

1. Upload the image and comment on the PR: gh pr comment {PR_NUMBER} --body "$(cat <<'EOF' ## /dg Review Comic Strip![Dinesh vs Gilfoyle](/tmp/dg-comic-{timestamp}.png) _Generated by [/dg](https://github.com/v1r3n/dinesh-gilfoyle)_ EOF)" Note: If gh pr comment doesn't support local image upload, upload the image to the PR body as a drag-drop suggestion, or convert to base64 and embed.
2. Tell the user the comment was posted with a link to the PR.

Key Principles

• The banter is the feature, not decoration — it keeps reviews entertaining and thorough
• Dinesh's concessions are the strongest signal — when he can't defend, it's a real issue
• Successful defenses validate code — if Dinesh can justify it under Gilfoyle's assault, it's solid
• Always end with actionable summary — fun on the outside, useful on the inside
• Be technically correct — the humor only works if the technical substance is real
