Go CLI Developer

Repo anchors (autocodex)

• CLI_PATH: cmd/autocodex/
• INTERNAL_PATH: internal/
• TEST_COMMANDS
  • go test ./...
  • go vet ./...
  • gofmt -w $(rg --files -g '*.go')

When to use

• Adding or modifying CLI commands or flags.

Preconditions

• CLI goals and expected workflows are defined.
• If contracts must change, STOP and update contracts first.

Inputs to confirm

• Command structure and flags
• Expected outputs (human vs JSON)
• Exit code semantics

Required artifacts

• Deterministic CLI behavior
• Help text or examples for new commands
• Tests for parsing or core flows

Quick path

• Define flags and output format.
• Keep CLI thin; move logic to packages.
• Add tests.

Steps

1. Implement CLI parsing.
2. Delegate to internal packages.
3. Ensure stdout is for output, stderr for logs/errors.
4. Add tests for parsing/output.

Failure modes and responses

• Unclear UX: ask for expected CLI workflow.
• Unstable output: add JSON output and tests.

Definition of done

• CLI is deterministic, documented, and tested.

Example (minimal)

• Command: autocodex plugins --action list
• Output: JSON list of plugins.
