Core trick
Scores candidates on sandboxed agent sessions where they drive Claude toward working software, graded from their traces rather than memorized algorithms.

Deployed Live - www.vibeforces.tech
The thing I kept thinking about, walking into this hackathon, was how unrecognizable our hiring pipelines have become from the way we actually build software now. I write code with Claude every day. So does almost every engineer I know. Yet the interviews we still give look like 2018 — reverse a linked list, balance a binary tree, prove you can manually do the thing the model now does in two seconds.
There are mass vibecoders now. There is no standardized way to train them. No way to test them. No way to rank them. Engineers who ship with Claude are an entirely different population from engineers who ship without — and the industry has no instrument for telling them apart.
I built VibeForces to be that instrument. A competitive assessment platform with Codeforces-style ratings, public leaderboards, live contests, and a recruiter test builder that lets companies grade candidates on how well they drive a model toward working software, not on how many algorithms they memorized. There are categories for spec-to-prompt translation, token-efficient golfing, bug-fix prompting, architecture ranking, and UI reproduction.
Then there's the part of the platform I'm proudest of: a senior track where the candidate doesn't write a prompt — they drive an agent. Real distributed bugs reproduced and patched inside sandboxed sessions. Services built end-to-end. Agents designed, instantiated, and graded by their trace. That whole track lives inside Claude Managed Agents, because it couldn't have lived anywhere else.
Three roles, full auth, deployed live at vibeforces.tech.
You're not hiring someone who memorized merge sort anymore. You're hiring someone who can ship with Claude. VibeForces is where that question gets answered.

README excerpt
# VibeForces **LeetCode for vibecoders.** A competitive assessment platform for the engineering skill that actually ships software in 2026: prompting, debugging, and orchestrating AI. **Submission:** Built with Opus 4.7 — Claude Code Hackathon **Live:** [vibeforces.tech](https://vibeforces.tech) **Author:** Shivam Dwivedi · [@dwivediishivam](https://github.com/dwivediishivam) **License:** MIT --- ## Why this exists LeetCode tests whether you can reverse a linked list. Eighty percent of startups now ship code through AI. There is no standardized way to train, test, or rank the skill that actually moves the needle in a 2026 engineering org — the ability to drive a model toward working software. VibeForces is two things in one platform: 1. **A training ground for engineers** who want to get measurably better at prompt-driven work. 2. **A hiring instrument for recruiters** who are tired of testing the wrong thing. Three roles (learner / recruiter / admin), Codeforces-style ratings, public leaderboards, live contests, recruiter test builder with shareable links. --- ## The two tiers ### Tier 1 — SDE1 / SDE2 (5 categories, 30 challenges) The skills you'd test for an entry-to-mid-level role at a startup: | Category | What it tests | |---|---| | **Spec-to-Prompt** | Listen to a voice-note spec. Write a prompt that produces the described output. Plan-and-act mode at higher difficulties. | | **Token Golf** | Achieve the target output in the fewest possible tokens. Efficien
