+# TTYverse Agent Guide
+
+## Project Layout
+- `ttyverse.pl` is the main (large) Perl script and source of truth.
+- `ttytter.pl` is the original upstream script for reference.
+- `extensions/` contains optional extensions.
+- `ttyverse.wiki/` contains user and developer documentation.
+
+## Run
+- `./ttyverse.pl`
+- `perl ttyverse.pl`
+- `./ttyverse.pl -version`
+
+## Testing
+- No automated test suite is present.
+- Minimum sanity check after edits: `perl -c ttyverse.pl`.
+- Manual checks are expected (login, timelines, posting, notifications, media, polls).
+
+## Coding Standards
+- Follow the existing code style in `ttyverse.pl`.
+- New code should use camelCase variables, snake_case functions/methods, and PascalCase class names.
+- For bash scripts, all variables must be camelCase (except system env vars). Run `shellcheck` on any edited bash script and fix issues.
+- Log lines should be `message [timestamp]` (message first).
+
+## Accessibility
+- Do not use Speech-Dispatcher or `spd-say` in GUI contexts.
+- Prefer clear, complete labels and avoid keyboard traps.
+
+## System Interactions
+- If a task requires `sudo`, ask the user to run it.
