('Short list of things that make this repo stand out (vs. Cursor / Windsurf):\n'
 '\n'
 '- Native Emacs-first design\n'
 '  - The entire chat is an editable Emacs buffer (markdown-like), not a '
 'locked UI panel — you can edit assistant output, thinking blocks, tool '
 'calls, save chats as files and continue them.\n'
 '  - Tree‑sitter grammar for the chat format: syntax/highlighting, folding, '
 'clickable citations/URLs, TAB-based expansion.\n'
 '\n'
 '- Tooling as Emacs Lisp\n'
 '  - Tools are ordinary Emacs Lisp functions you register; you can write and '
 'register arbitrary tools (file ops, ripgrep, shell, web read/search, etc.) '
 'and pass buffer/callback/metadata/streaming hooks.\n'
 '  - Server tools (e.g., web_search) are modeled and registered too (JSON '
 'schema strings).\n'
 '\n'
 '- Safe, auditable file editing workflow\n'
 '  - File edits are done by explicit named tools (str-replace, replace-file, '
 'write-new-file, etc.) with checks (e.g., paren-balance for .el).\n'
 '  - Greger stages/commits changes to git automatically (and can commit the '
 'chat file) so every agent edit has git provenance.\n'
 '\n'
 '- Streaming + tool execution model\n'
 '  - Assistant text is streamed incrementally; tool calls are recognized and '
 'executed (in parallel) with placeholders inserted and streaming/tool '
 'callbacks that fill results back into the buffer.\n'
 '  - Terminal/control‑sequence processing so CLI progress bars and streaming '
 'outputs render sensibly in the buffer.\n'
 '\n'
 '- Rich UI transformations\n'
 '  - Tool inputs/results get syntax highlighting (creates a temp buffer with '
 'appropriate major-mode based on file path), unified-diff generation for '
 'str-replace, and “undiff” parsing back to original/new content.\n'
 '  - Folding/invisibility of tags, citation folding, and clickable links all '
 'implemented with tree‑sitter + text properties.\n'
 '\n'
 '- Claude & Anthropic features baked in\n'
 '  - Built specifically for Claude models, uses prompt-caching/ephemeral '
 'cache-control, explicit "thinking" blocks (separable internal reasoning '
 'budget).\n'
 '  - Uses curl-based streaming client with fine-grained content-block '
 'callbacks.\n'
 '\n'
 '- Security / UX choices\n'
 '  - Shell-command tool asks for permission unless a safe-command allowlist '
 'or allow-all flag is set; metadata carries safe-shell-commands.\n'
 '  - Minimal external deps (only curl + common CLI tools) — Emacs-native '
 'instead of requiring a separate service.\n'
 '\n'
 '- Extensibility & tests\n'
 '  - Easy to add custom tools (three-step process) and many examples.\n'
 '  - Large test suite and emphasis on correctness (parsing, diffing, tool '
 'plumbing).\n'
 '\n'
 'In short: Greger is built as an Emacs-native, fully-text, tree‑sitter‑aware '
 'agent framework where tools are first‑class Emacs Lisp functions and every '
 'change is tracked and reviewable in git. That combination (editable '
 'chat-as-file, Emacs Lisp tool extensibility, tree‑sitter UI/diffing, git '
 'provenance, and streaming/tool plumbing) is the repo’s primary '
 'differentiator compared to web/IDE‑centric agents like Cursor or Windsurf.')
