Github Top Trending Tool Just Fixed The AI Agent’s Biggest Problem

Claude skills are how Graft plugs into Claude Code, so this is also a Claude skills guide: what are Claude skills, how to use Claude skills, and Claude skills explained, on a tool that cuts the tokens your agent burns searching your project.

WHY YOUR AGENT BURNS TOKENS BEFORE IT CHANGES ANYTHING

- Coding agents search your project with terminal commands before every edit, and rarely find the right file on the first try
- Every one of those turns resends your whole conversation plus all the earlier tool results
- The context window grows, the model slows down, and you hit your usage limit sooner
- Quality drops too, because there is too much in the window to focus on one thing
- Worst on high end models like Opus, GPT Astra and Fable 5.1, where one task already takes a while

WHAT IS CONTEXT ENGINEERING, AND WHY IT MATTERS HERE

- Context engineering is deciding what actually reaches the model instead of letting the agent discover it from scratch
- Graft's answer is a knowledge graph: a map of every part of your project and how the parts connect
- Each part is a node, each link is an edge, saved as a JSON file with a browser viewer you can explore
- Other tools use vector search, which matches by similarity, so "create an account" and "delete an account" both look right. The map records which part actually uses which

CLAUDE CODE SKILLS, HOOKS, AND HOW GRAFT INSTALLS

- How to add skills in Claude the easy way: the graft init command creates the skill inside your project folder for you
- So if you have looked at how to create Claude skills, this is the version where the tool generates it
- The skill tells the agent how to use Graft and which commands it has, which is what skills Claude loads at session start are for
- It also installs hooks, and the video explains what a hook is: a small script that runs on its own at a set point
- AI automation at the plumbing level: one hook hands over the instructions at session start, one attaches up to three matching locations to every prompt, one updates the map after Claude edits a file
- For a project you already started, graft build maps the code that is already there

HOW TO USE CLAUDE SKILLS LIKE THIS ONE IN A REAL PROJECT

- Claude skills tutorial style walkthrough: copy the install command, or paste their setup prompt into your agent and let it install everything
- Run init inside the folder you are working in, pick your coding agent, and the setup lands in that project
- Works with Claude Code and Codex, and other AI agents that use terminal commands or MCP
- There is an MCP option too. With hooks, Graft attaches locations to every message. With MCP, the agent asks only when it needs something. In their tests MCP got a few more answers right, the CLI was faster, and you get both
- No separate API key, so it runs on your normal Claude AI subscription

THE NUMBERS FROM THEIR BENCHMARK

- Best case, four times cheaper in token usage
- Across 162 runs: 60% less time, 46% fewer tool calls, 42% fewer tokens, 32% lower cost on average
- The saving comes from searching the agent no longer does, so it pays off more the bigger the project

WHAT HAPPENED WHEN WE BUILT A REAL APP WITH IT

- A booking and scheduling app, like Calendly but for independent providers, built with Fable 5.1 twice, once with Graft and once without
- With Graft: 39 minutes and about 31% of the context window. Without: 47 minutes and about 35%. Both apps worked
- The gap widened after that. A full landing page revamp took under 2 minutes, then Graft updated the map and showed its estimate of the tokens saved
- We started from a PRD and a claude.md tuned for long autonomous runs, and that template is in AI Labs Pro

THE HONEST LIMITATION

- Graft only maps code, so your PRD, area files and learnings.md are still read the old way
- We modified it for projects with multiple plan files, and that version is in AI Labs Pro

One of the best Claude skills is the one you never think about, and this is that kind of tool. If you build with AI tools every day and your agent eats your limit before it writes a line, this is the fix. More AI, Claude and Claude Code workflows every week.
