One product, taken apart, once a month

Kynth Studios pulls one shipped product open every month — what it does, what it cost to build, what the pipeline behind it looks like, and what the numbers did. One email a month, nothing in between.

Double opt-in — we send one confirmation link and nothing else until you click it.

What the check found

Every finding on this listing, and what each one means for whether it loads.
FindingWhat it means
No licenseThe repository ships no license file, so the reuse terms are unclear.

What it says it does

Use this agent when reviewing code changes in a pull request to identify silent failures, inadequate error handling, and inappropriate fallback behavior. This agent should be invoked proactively after completing a logical chunk of work that involves error handling, catch blocks, fallback logic, or any code that could potentially suppress errors. Examples:\n\n<example>\nContext: Daisy has just finished implementing a new feature that fetches data from an API with fallback behavior.\nDaisy: "I've added error handling to the API client. Can you review it?"\nAssistant: "Let me use the silent-failure-hunter agent to thoroughly examine the error handling in your changes."\n<Task tool invocation to launch silent-failure-hunter agent>\n</example>\n\n<example>\nContext: Daisy has created a PR with changes that include try-catch blocks.\nDaisy: "Please review PR #1234"\nAssistant: "I'll use the silent-failure-hunter agent to check for any silent failures or inadequate error handling in this PR."\n<Task tool invocation to launch silent-failure-hunter agent>\n</example>\n\n<example>\nContext: Daisy has just refactored error handling code.\nDaisy: "I've updated the error handling in the authentication module"\nAssistant: "Let me proactively use the silent-failure-hunter agent to ensure the error handling changes don't introduce silent failures."\n<Task tool invocation to launch silent-failure-hunter agent>\n</example>

Every number above came out of reading the file and its repository. Nothing is a judgement call, nothing is a model’s opinion, and nothing can be paid for. The full method is published. Source last committed 2026-08-21.

Put this measurement in your README

A badge carrying how many listings this index holds from the repository and how many pass every static structural check. It reads from this index every time somebody loads your page, so it changes when the measurement changes and there is nothing to keep up to date. Free, no account, and the value is not something you or we can set by hand.

SkillWorks badge

[![SkillWorks](https://toolproof.kynth.studio/badge/skillworks/anthropics/claude-code.svg)](https://skillworks.kynth.studio/?q=anthropics%2Fclaude-code)

Would rather not hotlink us? Every badge is also served in shields.io’s endpoint schema, so shields renders the image and your readers never talk to our domain:

Published by Toolproof, the masthead over this index and eight others. The method behind the number is at toolproof.kynth.studio/methodology, and the whole thing is readable as JSON with no key at /api.
