We Have Code Review. We Need Intent Review.
The article argues that AI coding agents (e.g., Claude Code) frequently produce reasonable code that nevertheless violates recent team decisions because agents lack structured access to a project's decision history. The author proposes adding an "intent review" layer that records team decisions as structured, queryable records and surfaces them automatically to agents before they change code. The author describes Mainline, an open-source (Apache 2.0) tool in private beta that stores sealed intent records in git refs (e.g., refs/heads/_mainline/actor/<id>, refs/notes/mainline/intents). Sealed intents include summaries, decisions, risks, and fingerprints of touched files. The post explains design trade-offs, early dogfooding results, and argues git-native structured intents are a foundation for reliable, compound AI-assisted engineering.
Proposes a developer workflow and tool (Mainline) that could improve reliability of AI-assisted coding across teams, but it is a niche engineering practice/tool in private beta rather than an industry-shifting platform announcement.

Key Takeaways & Evidence Grounding
- AI agents can generate reasonable code that conflicts with undocumented recent team decisions because they only see code, not decision history.
- The author proposes "intent review": a pre-change review layer that exposes structured team decisions to agents before edits.
- Mainline is an open-source (Apache 2.0) tool, currently in private beta, that records structured intent records in git using refs and notes.
- Mainline sealed intents include summary.what, summary.why, decisions[], risks[], and a fingerprint of touched files and subsystems.
- Design choices for Mainline include a process-based CLI (not a daemon), intent-level (task-level) records, explicit sealing, and an append-only immutable history.

Review AI-Generated Code with Multiple AI Agents
The article describes a workflow for reviewing AI-generated code using multiple AI agents and retaining the full agent session as review context. It argues that code diffs and commit history alone do not capture the reasoning and intent that led to an implementation. Entire (entire.io) captures prompts, agent responses, tool calls, inspected files, constraints, and decisions via checkpoints and integrates that context with Git. Using an "entire review" profile, teams can run multiple reviewer agents in parallel and have a judge consolidate findings, enabling checks for technical correctness and whether the final code matches the original prompt (catching intent drift).
Five-stage workflow for safe AI coding agents
The article describes a five-stage, tool-agnostic workflow teams can use to manage AI coding agents so machine-written pull requests remain reviewable and aligned with human intent. The workflow moves human effort to defining intent and verifying results through artifact-driven gates: a spec packet (intake), splitting work into bounded tasks, agent implementation within explicit write scopes, an evidence file with test outputs, and a checklist-based human PR review. The piece emphasizes preventing out-of-scope silent decisions, running agents in isolated branches, serializing tasks that share files, and measuring review time, out-of-scope edits caught, and rework rate during early adoption.
Multi-Agent Code Reviews Need Pipelines
Developer Nimesh Kulkarni argues that as AI generates more code, single-agent workflows are unsafe and unscalable. Instead of asking one model to both write and validate code, teams should build multi-agent review pipelines where specialized agents (implementation, test, security, architecture, summary) run after deterministic CI checks. Continuous Integration should act as the control plane: run linting, types, and tests first, then trigger focused AI reviewers with narrow prompts and scoped permissions, aggregate findings, and escalate only risky items to humans. The post warns that Model Context Protocol (MCP) and similar tool layers make integrations easy but increase risk, so agents should start read-only, have logged tool calls, and never be given broad write/deploy permissions without higher safeguards.
