zed/crates/eval_cli

eval-cli

Headless CLI binary for running Zed's agent in evaluation/benchmark environments. Designed to work inside containerized environments like Harbor where the repository is already checked out and API keys are provided via environment variables.

Uses the same NativeAgent + AcpThread pipeline as the production Zed editor — full agentic loop with tool calls, subagents, and retries, just without a GUI.

Building

Native (for local testing on the same OS)

cargo build --release -p eval_cli

Cross-compile for Linux x86_64 (from macOS or other hosts)

Harbor containers run Linux x86_64. Use the Docker-based build script:

crates/eval_cli/script/build-linux

This produces target/eval-cli (an x86_64 Linux ELF binary). You can also specify a custom output path:

crates/eval_cli/script/build-linux --output ~/bin/eval-cli-linux

Standalone usage

eval-cli \
  --workdir /testbed \
  --model anthropic/claude-sonnet-4-6-latest \
  --instruction "Fix the bug described in..." \
  --timeout 600 \
  --output-dir /logs/agent

Reads API keys from environment variables (ANTHROPIC_API_KEY, OPENAI_API_KEY, etc.). Writes result.json, thread.md, and thread.json to the output directory.

Exit codes

Code	Meaning
0	Agent finished
1	Error (model/auth/runtime failure)
2	Timeout
3	Interrupted (SIGTERM/SIGINT)

Harbor integration

The zed_eval/ directory contains a Python package that implements Harbor's BaseInstalledAgent interface, allowing eval-cli to be used with --agent-import-path without modifying Harbor's source code.

Setup

pip install -e crates/eval_cli/harbor/

Running with a local binary

Build for Linux first, then pass the binary path:

crates/eval_cli/script/build-linux

harbor run -d "swebench_verified@latest" \
  --agent-import-path zed_eval.agent:ZedAgent \
  --ae binary_path=target/eval-cli \
  -m anthropic/claude-sonnet-4-6-latest

The agent uploads the binary into the container during setup — no download URL needed during local iteration.

Running with a download URL

For CI or when the binary is hosted somewhere:

harbor run -d "swebench_verified@latest" \
  --agent-import-path zed_eval.agent:ZedAgent \
  --ak download_url=https://example.com/eval-cli \
  -m anthropic/claude-sonnet-4-6-latest

Setting a timeout

Pass EVAL_CLI_TIMEOUT via --ae:

harbor run -d "swebench_verified@latest" \
  --agent-import-path zed_eval.agent:ZedAgent \
  --ak binary_path=target/eval-cli \
  --ae EVAL_CLI_TIMEOUT=600 \
  -m anthropic/claude-sonnet-4-6-latest
