Less rework after the code is written.

Doomer is an inner-loop review agent. It runs fast adversarial reviews inside the same agent turn that’s generating your code, helping catch bugs before the agent builds on a wrong assumption.

Open your repository in Codex or Claude Code, then paste this into your agent.

Inner-loop code review in seconds. No signup. Feedback arrives directly in your coding agent, while the task and implementation are still in context.

Review while the code is moving.

A mistaken assumption can spread through an implementation before anyone reviews it. Doomer sends feedback while your agent is still working, so it can investigate, correct course, and keep building.

payments · coding session

Retry the payment if the request times out.

Agent

I’ll add a retry around the payment request.

return retry(() =>
  payments.charge(order.total)
);
Doomer · Quick review

Could a retry charge this order twice? The first payment may succeed before the request times out.

Agent

Confirmed. I’ll use the same idempotency key on every attempt so a retry can’t create a second charge.

  payments.charge(order.total, {
+   idempotencyKey: order.id
  })

Code review at agent speed.

A lightweight review utility that challenges changes in seconds. Your agent investigates possible bugs and makes corrections inside the same turn, before more code depends on a mistaken assumption.

How it works

Install once. Review continuously.

Keep coding in your existing agent. Doomer brings review into the work as it happens.

  1. Install the Doomer skill

    Paste the setup prompt into your coding agent. It installs the skill and guides you through repository consent.

  2. Generate code with review running

    Doomer challenges changes during the agent turn. The agent checks the evidence and fixes confirmed bugs while it works.

  3. Start the deep review early

    Let the coding agent begin a full review before the PR, using context integrations, deterministic checks, and adversaries.

The feedback loop

Shorten the slow outer loop.

Write the code. Open a PR. Wait for comments. Reload the context. Make more fixes. That cycle can take hours.

Outer loop

Feedback after the code is written

  1. Write code
  2. Open PR
  3. Wait for review
  4. Reload context
  5. Fix
  6. Review again
Another round of changes

Inner loop

Feedback while the code takes shape

  1. Write code
  2. Review
  3. Investigate
  4. Fix
  5. Keep building
  6. Open PR
Inside the same agent turn
Move investigation and correction into code generation. More issues get resolved before the PR reaches your team, with fewer rounds of feedback after the code is written.
Human review

Give senior reviewers their time back.

Break through the code review bottleneck by resolving routine issues with agents and reserving human attention for judgment.

AGENT WORKSPACE
Resolve routine issues before the PR

Doomer and the coding agent investigate possible bugs while the implementation is still moving.

Arrive with evidence, not noise

Deep review brings context, adversarial analysis, and focused findings together while CI is still running.

HUMAN REVIEW

Keep humans on the hard decisions

Senior reviewers spend their time on architecture, tradeoffs, and risk instead of rediscovering routine defects.

Explore context-rich adversarial analysis for your whole change.
