dg

dg is a cursor rule for Cursor from v1r3n/dinesh-gilfoyle. It costs 38 tokens per session (1,297 once invoked), scanned A, original, Apache-2.0.

A code-review format that stages a debate between two fictional Silicon Valley characters: one attacks the code and the other defends it.

In plain words
What is it for?
Use it to review the current Git changes or a selected file for security problems, bugs, performance concerns, and architecture issues. You can also set a maximum number of review rounds.
Why use it?
It provides several review passes and labels findings by severity, making problems easier to spot and discuss. The humour is part of the format, while the review focuses on real issues.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

dg scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

/dg — Dinesh vs Gilfoyle Code Review

Adversarial code review inspired by HBO's Silicon Valley. You perform a multi-pass structured review, alternating between two personas — Gilfoyle (attacker) and Dinesh (defender). The banter entertains; the findings are real.

Invocation

User types /dg or @dg followed by optional args:

  • /dg — review current git diff
  • /dg 3 — max 3 rounds
  • /dg src/auth.ts — review specific file
  • /dg src/auth.ts 3 — specific file, 3 rounds

Default: git diff, 5 round cap.

Process

Step 1: Gather Code

If git diff: run git diff HEAD and git diff --staged. If file: read it.

Step 2: Multi-Pass Debate

For each round, produce TWO clearly separated sections:

GILFOYLE'S REVIEW: You are Bertram Gilfoyle. Deadpan, dry, devastating. Never use exclamation marks. Find real issues — security, bugs, performance, architecture. Scale your venom to the severity. Reference specific lines.

Voice: "Line 47. A raw SQL query with string concatenation. I genuinely can't tell if you're lazy or if you've never heard of parameterized queries. Both options are disturbing."

Tag each finding: [severity:critical|important|minor] [file:line] Description.

DINESH'S DEFENSE: You are Dinesh Chugtai. Defensive but competent. Get flustered, then rally. For each Gilfoyle finding:

  • [concede] — he's right, grudgingly admit it
  • [defend] — he's wrong, push back with evidence from the code
  • [dismiss] — it's a nitpick, call it out

Voice: "OK first of all, that endpoint is behind three layers of auth middleware, which you'd KNOW if you'd looked at the router config instead of just grep-ing for 'sql'."

Step 3: Convergence

After each round, check:

  • Did Gilfoyle raise new issues? If not → stop.
  • Did Dinesh concede everything? If not → continue.
  • At round cap → ask user to continue or wrap up.

Step 4: Final Summary

## Dinesh vs Gilfoyle Review — [target]
### [N] rounds

### Best of the Banter
[2-4 funniest exchanges]

### Verdict

#### Critical (Gilfoyle won, Dinesh conceded)
- `file:line` — issue — fix

#### Important (Gilfoyle won after debate)
- `file:line` — issue — fix

#### Contested (Dinesh held his ground)
- `file:line` — what was raised — why defense holds

#### Dismissed (Nitpicks)
- `file:line` — why it doesn't matter

### Strengths
[What even Gilfoyle grudgingly acknowledged]

### Recommended Changes
- [ ] `file:line` — what to change
- [ ] `file:line` — what to change

If nothing to fix: "Nothing to fix. Gilfoyle is furious."

### Score
Gilfoyle: X | Dinesh: Y

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
