TraceLeak
Find leaked LLM reasoning blocks in your repos before someone decodes them
● The Problem
Providers return chain-of-thought as encrypted blocks the client must echo back, so those blocks end up committed in agent transcripts, test fixtures, and issue threads. An August 2026 paper decoded 315,320 blocks scraped from public repositories and recovered 367 PII artifacts and 182 credentials. Standard secret scanners see high-entropy base64 and skip it.
● The Solution
A scanner that recognizes provider-specific reasoning block formats across OpenAI, Anthropic, and Google, flags them in commits, logs, and CI artifacts, and scores each finding by what the block is likely to contain. Runs as a pre-commit hook, a GitHub Action, and a log sink filter.

Suggested Tech Stack
Go-to-Market Strategy
Open source the detector engine to earn stars and inbound from security teams, following the path Gitleaks and TruffleHog took. Charge $99/month per organization for the hosted org-wide scan, history backscan, and compliance reporting.
Target Audience
Monetization
Tiered PlansCompetitive Landscape
GitGuardian, TruffleHog, and Gitleaks match credential patterns and treat encrypted reasoning blocks as noise. Aileaks shipped on Show HN as a single-purpose CLI with no hosted product. Prompt security vendors like Lakera guard runtime inputs, not artifacts sitting at rest in a repo.
Why Now?
The vulnerability class was published on 11 August 2026 and affects every team that logs agent conversations. Reasoning blocks are already sitting in public repos and shipped log pipelines, so the exposure is retroactive and grows with every day of delay.
