From SkillCheck to TraceMantle: Tracking Agent Skill Changes and Test Evidence
1+ hour, 15+ min ago (637+ words) I’ve renamed SkillCheck to TraceMantle and expanded its scope. The original project focused mainly on validating AI agent skill files. TraceMantle retains that functionality and adds support for tracking the files in a skill package, comparing changes, and checking whether…...
Where AI review pays: the codebase matters more than volume
4+ hour ago (329+ words) The question I keep getting is how a team can review the growing volume of AI-generated code. Most answers start with throughput: faster review tools, more automated checking, larger batches. That assumes the problem is volume. The review I read…...
Fixing the Proxy Deleted the Objective: The Style Review Removed a CTA and Every Accuracy Gate Passed
4+ hour, 38+ min ago (181+ words) Originally published on hexisteme notes. Closing this out took more than restoring the CTA. Four changes, each aimed at a different point where the same shape of failure could recur: And I split the downstream metric so "no data yet…...
I built a ReDoS scanner that proves each bug offline — and hands you a verified fix
7+ hour, 7+ min ago (442+ words) A regular-expression denial-of-service bug is a regex whose backtracking engine can be pushed into super-linear (often exponential) time by a short, hand-crafted input. The textbook shape is a quantifier inside a quantifier: The scary part is that these patterns look…...
The Model Wrote the Right Rule and My Replay Rejected It: The Extraction-vs-Replay Split
6+ hour, 33+ min ago (528+ words) CauterRule is an open-source sidecar that learns standing rules from repeated agent failures. It extracts lessons from trajectories, replay-tests them, and tries to separate reusable guidance from noisy overgeneralization. For two releases we treated "the pass rate is low" as…...
Inside BeeLadybug: Visual Logic & Collision Debugging (CodePen Challenge)
8+ hour, 30+ min ago (616+ words) 🐞 BeeLadybug (v2.4.0) — Visual Debugging & System Monitoring Following up on my previous post about BeeLadybug, I wanted to map out its internal architecture for this week's CodePen Challenge using a clean Mermaid flowchart! BeeLadybug serves as the primary visual inspector for BeeEngine…...
A CSV diff should reject duplicate IDs before it reports changes

Why Static Mock APIs Aren't Enough for Modern Frontend Development
8+ hour, 57+ min ago (408+ words) Every frontend developer has experienced this sequence: Nothing happens. The list is identical to what it was before. Your newly created item has vanished into thin air. For over a decade, developers have accepted this as "normal" mock API behavior....
Postman Collection to MCP: From Requests to MCP Tools
9+ hour, 7+ min ago (720+ words) A Postman collection can be a surprisingly useful starting point for an MCP server. Many teams have Postman collections before they have polished OpenAPI documentation. The collection already contains working requests, paths, query parameters, headers, bodies, example responses, and authentication…...
A Screenshot Is Not an Agent Failure Artifact
9+ hour, 25+ min ago (593+ words) A screenshot of an execution tree looks useful in a pull request. It is also missing almost everything a skeptical reviewer should ask: Raw JSONL answers some of those questions and creates another problem: it may contain identifiers, attributes, or…...
