We need a multi-agent code review workflow for backend PRs. I was going to build a reviewer from scratch with 5 subagents. Before we commit, check the field: what has already worked, what broke, and what should we copy?
Claude I will check current tools, user reports, and failure modes before designing the workflow.

  • [repo] postmortemthis: multi-model PR review CLI using Claude Code, Codex, Gemini, Qwen, Vibe.
  • [docs] Claude Code review plugin: 4 parallel reviewers, confidence threshold at 80, final synthesis.
  • [docs] Cline workflow: model-orchestration consensus across Gemini, Codex, and Opus.
  • [problem] runaway subagents: user reports severe token burn and rate-limit exhaustion.
  • [method] ultracost-style gate: estimate spend before expensive agent fan-out.
Claude I found a likely dead end: unbounded subagents. I need the source records before changing the plan.

tool result - decisive records
  • postmortemthis already implements the same product shape: multi-model review, aggregate findings, final verdict.
  • The strongest working pattern is bounded fan-out: 3-4 reviewers, not open-ended subagents.
  • Findings need confidence, source file, line range, and evidence text, or users reject the review.
  • Cost controls are not optional: preflight estimate, per-stage routing, hard stop on budget.
  • Failure reports cluster around vague prompts, duplicate findings, and hidden token spend.
Claude
plan changed
  1. Do not build a reviewer from scratch.
  2. Clone the bounded consensus architecture.
  3. Use 3 reviewers: correctness, security, maintainability.
  4. Drop findings below confidence 80 unless two reviewers agree.
  5. Add budget preflight and stop before spawning expensive agents.
  6. Return only source-backed findings with file, line, evidence, and fix.
outcome skipped the five-subagent dead end, copied the field-tested pattern, and avoided the token-burn failure before writing code.

What TruthAPI Tracks

Technical Change

Repos, releases, APIs, docs, models, methods, papers, and status pages.

Field Evidence

Reddit, YouTube, X, Discord, user reports, buyer debates, incidents, and workarounds.

Linked Objects

People, products, organizations, problems, methods, use cases, and outcomes.

Avoid the silent trap.

That feature in the docs that compiles clean and 400s on every call — because the fix was quietly rejected weeks ago. Truth API catches it before you ship.

See the contradictions.

A launch claims a number the filing doesn't support. Two labs claim the same capability. Truth API holds both at once and shows which the sources back.

Tell signal from noise.

Seven accounts hyping one launch isn't traction. Eighteen people swarming one fix is. Truth API counts who, not just how many.

Better code starts with better judgment.

Give your agent the evidence to choose what to build—and how.
