File contents

AgentEnv CLI

Use agentenv to check environment prerequisites before running a model, sync task, or automation step.

Invoke the Tool

Prefer the installed binary when it exists:

agentenv OPENAI_API_KEY HOME

If working inside this repository or the binary is not installed, run:

go run ./cmd/agentenv -- OPENAI_API_KEY HOME

Choose Flags

Pass variable names as positional arguments for simple checks.
Use -file required-env.txt to load names from a file.
Use -allow-empty only when blank values are acceptable.
Use -show-values only when exposing raw values is safe.
Use -format json or -format yaml for automation.
Use -format text for human review.

Apply Good Defaults

Keep -strict=true for CI, startup checks, and agent preflight.
Avoid -show-values unless the environment is trusted and the output will not be logged.
Prefer JSON output when a caller will branch on missing keys.

Examples

Validate a known set:

go run ./cmd/agentenv -- OPENAI_API_KEY AGENT_HOME MODEL_NAME

Load from file:

go run ./cmd/agentenv -- -file required-env.txt -format json
