codeset — Onboard your coding agent

Codeset is a service that gives your coding agents, like Claude, the important background information about your team's codebase. It learns this by looking at your past code changes, tracking how functions are used, and checking your tests. Codeset then makes this knowledge ready for coding agents so they can understand your project.

Benefits

Codeset helps coding agents work much better. For example, Claude Haiku 4.5 with Codeset performs 10% better. Claude Sonnet 4.5 improves by over 9%, and Claude Opus 4.5 gets about a 7% boost. Using Codeset, especially with Haiku 4.5, can save money because it works so well.

Use Cases

Imagine a coding agent needs to fix a bug where charts weren't showing data correctly. The agent used Codeset's information, which pointed out a past change that stopped a certain column from being used. This knowledge helped the agent quickly find and fix the problem by changing the code that was being used.

Codeset finds hidden knowledge in your code that goes beyond simple notes. It can figure out which files often change together, which functions have been used incorrectly, and what past tricky situations have happened. This is all found by studying your code's history, tests, and structure.

The information Codeset provides includes details about past bugs and why they happened, specific problems related to certain files and how to avoid them, which tests check which parts of your code, which files are usually changed at the same time, and a map showing which functions call others and where.

For a small fee, Codeset creates a knowledge base for each file that agents can access. It also creates better overview files for agents that explain the project's structure, important commands, rules, and potential issues.

This detailed knowledge for each file includes past bugs and their causes, specific problems and their effects, all the functions that call a given function, and the tests that cover that file. This information is gathered automatically.

The process is simple: first, connect your code repository. Then, Codeset analyzes your code by studying its history, function calls, problems, and tests. Finally, you get overview files and a knowledge base for each file to use with your agent.

Pricing

Codeset costs $5 for each repository. This is a one-time payment, and there are no ongoing subscriptions. The analysis for a medium-sized project is usually done in about 45 minutes.
