contest

A workflow for building several competing implementations of the same coding task and having a judge compare them. It requires Claude Code's agent-team feature to be enabled.

In plain words
What is it for?
Running implementation bake-offs, evaluating alternatives against stated criteria, and choosing the best result.
Why use it?
It helps compare different solutions when there is more than one reasonable way to solve a problem.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

contest scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 329 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Competing Implementations

Spawn multiple implementers to build different solutions to the same problem. A judge evaluates and picks the best one.

Prerequisites

Agent teams must be enabled in Claude Code settings:

CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1

If agent teams are not enabled, report: "Agent teams required. Add CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1 to your Claude Code settings (env section)." and stop.

Arguments

  • $ARGUMENTS - Required: the problem to solve, ideally with evaluation criteria (e.g., "optimize the search function -- prioritize readability over raw speed")

If no arguments are provided, ask the user what they want implemented.

Context

  • Current branch: !git branch --show-current
  • Git status: !git status --short
  • Base ref: !git branch -r 2>/dev/null | grep -oE 'origin/(main|master)' | head -1
  • Project root: !pwd
  • Project type: !find . -maxdepth 1 \( -name go.mod -o -name Gemfile -o -name package.json -o -name Cargo.toml -o -name pyproject.toml -o -name setup.py -o -name requirements.txt -o -name pom.xml -o -name build.gradle -o -name Makefile \) 2>/dev/null | head -5
  • Recent commits: !git log --oneline -5
  • Test files: !find . -maxdepth 4 -name "*_test.*" -o -name "*.test.*" -o -name "*_spec.*" 2>/dev/null | head -10

Overview

You are the contest coordinator. Your job is to frame the problem, assign it to multiple implementers working in separate worktrees, and have a judge pick the winner.

Problem: $ARGUMENTS

You do NOT implement or judge yourself. You coordinate the contest.

Why this works: For design problems with multiple valid solutions (performance optimization, API design, architecture choices), building 2-3 options and comparing is faster and more reliable than debating hypothetical trade-offs.


Phase 0: Setup

  1. Clean working tree: If there are uncommitted changes, commit them with message "WIP: pre-contest state" before proceeding.

  2. Analyze the problem and define evaluation criteria. If the user didn't specify criteria, propose them:

    • Correctness (tests pass)
    • Readability / maintainability
    • Performance (if relevant)
    • Simplicity (fewer lines, fewer dependencies)
    • Consistency with existing codebase

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

contest is a skill published in the GitHub repository drn/dots (23 stars, last pushed 4d ago), licensed MIT. It adds 26 tokens to every session and 2,520 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
