LGTM, Ship It: The AI Code Review Problem

Main summary

Key takeaways

Technology

AI-written code that’s hard to maintain/read

AI agents generating large UI components can produce convoluted patterns (e.g., deeply nested calls and heavy reliance on side effects/effect logic), making the code harder to reason about.

Tactics to improve understanding and maintainability

  • Add terse, inline comments that document intent next to the code.
  • Enforce a style guide via prompts to make output more deterministic, e.g.:
    • In Svelte: “no effects / avoid side effects”
    • In React: be cautious because effects are often overused
  • Review in smaller chunks: change incrementally and zoom in rather than tackling huge blobs at once.
  • Use smaller, targeted edits instead of expecting AI to correctly factor everything perfectly.
  • Be explicit about when to duplicate vs extract utilities:
    • Duplicate when behaviors overlap but aren’t cleanly factorizable.
    • Extract shared logic into global utilities, and ensure prompts enforce:
      • “Check the shared utilities directory first; don’t create local duplicates”
    • This reduces repetition and “inline utility sprawl.”
  • Use linting / deterministic tooling so reviewers can focus on mission-critical areas rather than manually inspecting every line.

The “AI code generation” bottleneck: PR volume and review debt

A workflow is described where engineers:

1) ask an agent for a feature/bugfix 2) open a PR 3) address automated review comments 4) wait for CI to pass 5) merge with little/no meaningful human review

Reported scale problem

  • Up to ~60 PRs per contributor per week
  • PRs can span 20–70 files and thousands of lines

Consequences observed

  • Increasing technical debt
  • Recurring bugs
  • Architecture inconsistencies
  • Fragile implementations
  • Codebases becoming harder to extend/maintain

Key analysis shared

  • Even with “new superpowers” (AI), core engineering rules haven’t changed—the process just runs faster and creates mess sooner.
  • AI tends to add code more easily than remove/refactor it, so “debt fixes” may still leave long-term problems.
  • Without tests and strong review/architecture discipline, undoing AI-generated duplication becomes very difficult.

Explainer: what “local models” actually are

Clarified definition

  • Local models run on your local machine, not just “an API endpoint labeled local.”

Common misconception

  • Some call it “local” even when requests still go to third parties over the internet (e.g., “it’s going to China”).

Guidance/tooling

  • Referenced to CJ’s guide: “Your guide to local AI”.

Practical framing

  • “Local AI” isn’t necessarily one all-purpose super model—it’s often task-specific models (e.g., on Hugging Face) you can run in targeted ways.

Examples mentioned:

  • Transformers.js / Xenova for running certain models in-browser for real-time tasks such as:
    • detection/classification
    • speech
    • TTS
    • vectorization

Reality check

  • True “quality” local setups require substantial compute; expectations may not match hardware constraints.

Version control and agent workflows (Git alternatives + agent-friendly history)

JJ (“Jujitsu”)

  • Git-compatible behavior so standard tooling can still work (JJ can coexist with Git directories).
  • An operation log tracking revisions/snapshots in a unified log.
  • Undo capability, automatic staging/rebasing behavior, reduced need for stashing/branches:
    • uses bookmarks instead of branches
  • Criticism: some users see the lack of “true branches” as a major mental shift.

Zed Editor’s “Delta DB” (private beta)

  • Version control built around a coherent abstraction of agent conversation + worktree changes.
  • Stores fine-grained deltas with stable identities:
    • capturing not only commits, but operations between states
  • Motivation: preserve the “why” behind agent edits and keep artifacts reusable across interactions.

Takeaway

  • The “next Git/GitHub” may be about agent-scale workflows, where tooling handles huge volumes of automated changes and rollbacks.

Pricing for AI-accelerated freelance work

Fair pricing principle

  • Price based on value delivered, not time spent.
  • Time/effort billing can misalign incentives and lead to poor quoting decisions.

Notes on billing models

  • Hourly can work when scope is unknown, but for specific deliverables clients should pay for outcomes.
  • Token-based costs may be a new dimension (e.g., “$X worth of tokens”).

CSS standardization aside (WebKit box-reflect)

  • Safari/WebKit’s box-reflect wasn’t standardized; other browsers used vendor implementations.
  • Explanation given:
    • Apple likely added it for internal/trendy UI effects (like glossy reflections), and other browsers avoided standardizing trendy features.
  • It’s considered less useful today; alternatives like canvas-based approaches were suggested conceptually.

Angular ecosystem and dependency philosophy

A front-end developer asked how to get Angular teams to adopt more external libraries.

Discussion points

  • Angular teams often rely on framework-provided libraries (opinionated defaults), which can reduce experimentation with external packages.
  • Counterpoint: adding libraries costs; in the AI era, avoiding dependencies can be beneficial because:
    • AI can generate solutions using browser standards + small JS helpers
    • fewer dependencies reduces long-term maintenance risk

Example caution

  • An old dependency like Hammer.js (noted as last updated many years ago) can become “stuck” tech debt.

Product/guide highlights outside pure coding

“Sick pick” segments

  • Repairable long-life headphones (Bose QC 35) with pad/connector upgrades.

Robot demo (Hugging Face + Pollen “Richie Mini”)

  • A build-it-yourself expressive robot with:
    • camera
    • microphones/speakers
    • motors
    • Wi‑Fi
    • an app ecosystem
  • Connects to AI providers (example: Hermes) for:
    • chat
    • speech-to-text / text-to-speech
  • Build effort isn’t plug-and-play:
    • requires assembling multiple components/PCBs
    • compute can run on a laptop (vs. a Raspberry Pi variant mentioned as not available yet)

Future app ideas mentioned:

  • spelling practice
  • learning aids (including help for Warhammer 40K)
  • computer-vision motion/hand tracking using models like MediaPipe
