How I Audit Security Patches with an AI Pipeline

Posted on Sat 02 May 2026 in Thought, AI, Security Research • Tagged with chronicles, AI agents, WebKit, security research, vulnerability research, patch auditing, methodology

Most security patch auditing tools look for known vulnerability patterns. They diff a commit, grep for dangerous functions, maybe flag things that look like what last year's CVEs looked like. That works for the obvious stuff. It doesn't work for the commit that says "no behavior change" and silently fixes …

This is a follow-up to my previous post on routing agents through LiteLLM. That post covered the architecture. This one covers what broke when I actually ran it.

Claude Code Doesn't Pass Through Arbitrary Model Names

The first thing I got wrong: I assumed model: local-sonnet in agent frontmatter would …

This is a follow-up to my previous post where I covered reducing token costs in a multi-agent pipeline. That post touched on local model fallback at a high level. This one goes deeper on how the routing layer actually works.

The Pipeline

I have five agents, split across two tiers …

How I Cut AI Agent Costs Without Cutting Corners

Posted on Mon 20 April 2026 in Thought, AI, Security Research • Tagged with chronicles, AI agents, claude, pipeline, cost optimization, LLM

Running a multi-agent pipeline for security research gets expensive fast. I have several agents doing sequential analysis work - reading commit diffs, running adversarial bypass analysis, building proof-of-concept exploits. Token costs compound at every step: system prompts, tool schemas, conversation history, and verbose outputs all stack up before a single useful …

Evince Integer Overflow and Truncation Due to Type Promotion in TIFF Backend

Posted on Thu 01 August 2024 in Thought, vulnerability research and discovery • Tagged with chronicles, vulnerability research, vulnerability discovery, type promotion

I have been pretty facinated with type promotion bugs in the recent months. Why? Because I love when there is some crazy mixed data types with arithmetic. Something about math (in)correctly implemented always makes me geek out. For those not familiar with Type promotion, it's when data type values …
