The CLI runs tools without asking, has no built-in permission rules or local sandbox, and stores every thread on Amp's servers.\n\n**Kiro CLI.** Permission rules follow deny over ask over allow, cloned repositories can't add rules, and a headless session treats every ask as a deny. Content from Free and individual paid accounts is used for service improvement, including model training, unless the user opts out, and API keys for pipelines need a paid plan.\n\n## Before you call either\n\n### Amp\n\n1. Run unattended jobs in a container or VM. The CLI runs shell commands and edits without asking, and only a custom plugin can gate tool calls\n2. Set `AMP_API_KEY` to an access token starting `sgamp_` from Settings. The CLI rejects the short-lived token that `amp login` stores\n3. Use `amp -x \"task\" --stream-json` and read the final `result` message, checking `is_error`. Exit codes are not documented\n4. Set `AMP_SKIP_UPDATE_CHECK=1` or `amp.updates.mode` to `disabled` in CI. Updates install automatically by default\n5. Treat the block headed INSTRUCTIONS FOR LLMs in ampcode.com page source as vendor copy, and take facts from the docs Markdown\n\n### Kiro CLI\n\n1. Set `KIRO_API_KEY` and pass `--no-interactive` with `--trust-tools=\u003clist\u003e` in pipelines. Keep `--trust-all-tools` for disposable environments\n2. Pass `--require-mcp-startup` when a run depends on MCP tools. Without it a failed server is logged and the run continues\n3. Pass `--no-interactive` whenever input is piped from a source you don't control, and run 2.10.0 or later on Windows\n4. Run `kiro-cli settings telemetry.enabled false` and turn off content collection on Free and individual plans. Both are on by default\n5. Export variables in the shell before starting. Since 2.24.0 a project `.env` file is no longer loaded into sessions, MCP servers or tools\n\n## Questions\n\n### Which is better for AI agents, Amp or Kiro CLI?\n\nKiro CLI scores 59.9 (C) on agent readiness against Amp's 57.1 (C), and leads in 4 of 7 scored categories.
