+# cquote TODO
+
+## Core functionality (high priority)
+
+- [ ] Implement proper CSV line reader for `random`, `search`, and `list`
+  - Read one record at a time using `fgets`
+  - Parse fields with correct unquoting (handle doubled quotes `""`)
+  - Store quote, author, tags, and date in a struct
+
+- [ ] Finish `quote_random()`
+  - Count total quotes
+  - Pick a random one (using `srand(time(NULL))`)
+  - Print cleanly (quote on first line, author on second, tags on third)
+
+- [ ] Implement `quote_search(const char *term)`
+  - Case-insensitive substring match on quote, author, or tags
+  - Print matching quotes with context
+
+- [ ] Implement `quote_list()`
+  - Optional `--tag` filter
+  - Simple tabular output or one-per-line
+
+- [ ] Improve `quote_add()`
+  - Validate input (non-empty quote and author)
+  - Normalize tags (lowercase, no duplicates)
+  - Prevent duplicate quotes (optional)
+
+## cnotes integration
+
+- [ ] Create shell alias / wrapper examples
+  ```bash
+  alias cnquote='cquote random | cnadd -c Quote'
+  ```
+- [ ] Document in README how to pipe quotes into daily logs
+- [ ] *Optional*: Add a cnotes sub-command like cnotes quote
+
+## Future / nice-to-have
+
+- [ ] `--pipe` flag for clean output (no extra newlines)
+- [ ] Support multiple database files (-f filename)
+- [ ] `delete` or `archive` command (append to `.arc` like cnotes)
+- [ ] Integration with `proj`:
+
+```Bash
+proj c mytool --quote          # inserts random quote into README
+proj c mytool --quote "focus"  # uses tagged quote
+```
+
+## Testing & polish
+
+- [ ] Add basic test cases (manual or simple shell scripts)
+- [ ] Improve error messages and usage text
+- [ ] Ensure Windows/DOS compatibility (path handling, line endings)
+- [ ] Update README with usage examples and cnotes integration
+
+## Long-term ideas
+
+- [ ] Quote-of-the-day daemon / cron suggestion
+- [ ] Export to HTML or plain text
+- [ ] Fuzzy search
+
