This session burned $2.47
on the same mistake
four times.

Claude tried to import Stripe at module scope in a “use node” file. The build failed. Claude retried with a different import. Failed again. Retried. Failed. Retried. Four attempts, same root cause—one line in CLAUDE.md would have prevented all of them.

Error cascade detected — 4 retries from same root cause

Chapter 1 — Mission Control

Detected in real time.

The CLI daemon watches every Claude Code session. When the error cascade started, Mission Control flagged it immediately—cost, root cause, and wasted tokens, all visible in a single dashboard.

Investigated forensically.

One click opens the full transcript. Select the cascade messages, group them, annotate the root cause. Debug Studio traces the UUID chain automatically—no guesswork, no scrolling through logs.

Annotations
Root Cause
Stripe SDK initialized at module scope in “use node” file. Convex requires lazy init pattern.
+ Add to CLAUDE.md
Fix
Use lazy init: let _stripe = null; function getStripe() { ... }
Insight
This pattern has occurred in 3 of the last 12 sessions involving Convex actions.

Chapter 3 — Context Studio

Improved permanently.

The root cause annotation becomes a CLAUDE.md rule. Context Studio scores the change, confirms it improves the file, and previews the score delta before you commit.

# Convex Rules
 
## “use node” files
 
- Only contain actions (no queries/mutations)
- Split pattern: stripe.ts + stripeActions.ts
 
- Don't initialize SDKs at module scope —
  use lazy init: let _stripe = null;
  function getStripe() { if (!_stripe)
  { _stripe = new Stripe(...); } }
 
- No hyphens in Convex file names
## http.ts
- Cannot have “use node” — delegate to
  internal actions for Node.js work

Overnight, Dream Mode runs
Chapter 4 — Dream Mode

Compounded overnight.

While you sleep, Dream Mode runs a 6-stage pipeline: summarize sessions, detect patterns, analyze rule compliance, and generate an improved CLAUDE.md with before/after scoring. Review the diff, save to your project, or compare side-by-side in split editor.

☾

Dream Mode generated 1 improved CLAUDE.md

Analyzed 8 sessions. The lazy-init rule you added yesterday hit 95% compliance—working great. Found 2 new patterns and generated an improved version:

▲CLAUDE.md quality score 84 → 91+7
+Added: validate parentFolderId when creating folders (from pattern detection)
~Rewritten: Convex schema rule (was 25% compliance) (made more specific)

The Result

Session #4,292 gets it right
on the first try.

Same project. Same developer. Same Stripe integration task. But now CLAUDE.md has the rule—and Claude uses the lazy init pattern without a single error.
