AgentBench-Live CLAUDE.md

AgentBench-Live CLAUDE.md is an instructions file for coding agents from jackjin1997/AgentBench-Live. It costs 536 tokens per session, scanned A, original, MIT.

Project instructions for AgentBench-Live, a tool that compares coding agents on tasks. They describe the project's current goals, planned work, testing setup, and deferred features.

In plain words
What is it for?
Use them when maintaining AgentBench-Live, adding or updating agent adapters, running benchmark tasks in Docker, improving its comparison interface, or updating project documentation.
Why use it?
They give an agent the repository's priorities and working context before it changes code. This helps keep benchmark results, sandboxing, adapters, documentation, and the website aligned.

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

AgentBench-Live CLAUDE.md 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 4d 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.

Project Goal

Get on GitHub Trending. Current: 2 stars. Need: 50-150+ stars/day spike.

Strategy: Credibility First, Then Ride the Wave

  1. Fix trust gaps (Docker sandbox, more agents, real scores)
  2. Wait for a major agent launch, benchmark it day-1
  3. Coordinated multi-channel social push (Twitter, Reddit, HN, 小红书, V2EX)

Current Sprint Scope (accepted from CEO review 2026-03-19)

  • Docker sandbox (replace tempdir with real isolation)
  • Add Codex CLI adapter (already existed)
  • Add Aider adapter
  • Re-run ALL agents × ALL tasks with Docker (get real scores) ← USER ACTION NEEDED
  • Methodology doc (docs/methodology.md)
  • Frontend redesign (radar charts, domain filtering, hero section)
  • Social card generator (shareable comparison images)
  • Update README for 4 agents

Deferred (TODOS)

  • Agent Output Viewer (show actual agent work per task) — P2
  • GitHub Actions automated benchmark CI — P2
  • Automated nightly benchmark runs — Phase 2

Architecture

CLI (click) → Runner → Adapter Registry → SandboxFactory
                                            ├── DockerSandbox (primary)
                                            └── LocalSandbox (fallback)
                                         → Evaluator (auto + LLM judge)
                                         → Ranking → Leaderboard (GitHub Pages)

Key Technical Decisions

  • 4 agents: Claude Code, Gemini CLI, Codex CLI, Aider
  • Docker sandbox with fallback to local tempdir
  • SandboxFactory pattern (not inheritance replacement)
  • 1 trial for initial run, pass@k requires multiple trials
  • Sanitize API keys from logs/output

Critical Gaps to Fix

  1. Docker not available → fall back to LocalSandbox gracefully
  2. Agent timeout → record score=0 and continue, don't crash
  3. LLM judge failures → fall back to auto-eval, don't crash

Competitors

  • SWE-bench: ~4k stars (academic, GitHub issues)
  • PinchBench: ~640 stars (company-backed)
  • ai-coding-lang-bench: ~98 stars (language comparison)
  • TheAgentCompany: ~659 stars (simulated company)

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.
