No release since 0.86.2 on 12 February 2026 and no commit since 22 May 2026.\n\n**Amp.** Execute mode streams JSON in a format close to Claude Code's, with TypeScript and Python SDKs, and the security reference names each provider and what it sees. 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## Before you call either\n\n### Aider\n\n1. Read `.aider.conf.yml` in any cloned repository before starting aider. Its `test-cmd` and `lint-cmd` run without asking\n2. Script edits with `--message` and `--no-suggest-shell-commands`, not `--yes-always`\n3. Use Python 3.12 or earlier for the PyPI release\n4. Pass `--no-detect-urls` when the prompt holds links you don't want offered for scraping\n5. Check `git log` after a run. Each edit is its own commit\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## Questions\n\n### Which is better for AI agents, Aider or Amp?\n\nAmp scores 57.1 (C) on agent readiness against Aider's 46.9 (D), and leads in 4 of 7 scored categories.
