Sourcegraph Amp CLI Cheatsheet - Terminal AI Coding Agent Full Reference

Sourcegraph Amp is Sourcegraph terminal AI coding agent, for developers who need quick one-shot questions or want to push long tasks to run asynchronously in the background instead of blocking the foreground session. It is lightweight and controllable, organizing prompts and background jobs with threads. This sheet covers install/login, one-shot prompts, background execution, and thread management.

One-shot Prompts 5

amp "refactor user-auth to use the new session API"
Start a one-off task with an initial prompt
amp -x "list all TODO comments in this repo"
-x runs in execution mode (more action-oriented)

amp --no-stream
Disable streaming, return the result whole
amp --help
Show all commands and flags

amp --resume
Resume the most recent thread

Background & Integration 5

amp -x "run the test suite" &
Run long tasks in the background
amp --json "..."
Emit JSON for programmatic parsing
amp --cwd /path/to/repo "..."
Run with a specified working directory
AMP_API_KEY=... amp -x "..."
Headless CI task via API key
amp --verbose
Show per-turn tool execution details

Tips 5

amp -x is execution, amp is conversation
Pick the mode by intent
Isolate context per topic with threads
Open a thread per task
CI runs -x with AMP_API_KEY
Headless env needs no login state
--json feeds scripts
Structured output parses cleanly
Switch --model by need
Strong model for hard tasks, fast for light

Tips

  • Sourcegraph Amp is a terminal coding agent from Sourcegraph that can sit on multiple models; `amp` leans conversational, `amp -x` leans execution — pick by intent.
  • The threads mechanism isolates context per task so a long conversation does not pollute another — handy in complex projects.
  • In CI/headless, use `AMP_API_KEY` with `amp -x` for automation without interactive login.
  • `--json` output feeds scripts for programmatic parsing (quality gates, batch audits).
