+### Songs
+
+```bash
+recoup songs presets
+recoup songs analyze --audio "https://example.com/track.mp3" --preset catalog_metadata
+recoup songs analyze --audio "https://example.com/track.mp3" --prompt "Describe the production style"
+```
+
+Replace the example URL with your public audio URL. Every analysis requires audio
+and exactly one of `--preset` or `--prompt`.
+
+### Emails
+
+```bash
+recoup emails --text "Here is your weekly summary."
+recoup emails --text "Here is the update." --subject "Update" --chat-id <chat-id>
+```
+
+The recipient is resolved from your API key. `--subject` is optional; `--chat-id`
+adds a chat link. Use `recoup emails --help` for HTML, CC and organization-account options.
+
+### Content
+
+```bash
+recoup content templates
+recoup content validate --artist <artist-id>
+recoup content estimate --batch 2 --compare
+recoup content create --artist <artist-id> --template artist-caption-bedroom
+```
+
+Estimates use GET and do not start generation. `content create` starts the pipeline
+and returns run IDs; use those IDs with `tasks status` to check progress.
+
+### Tasks
+
+```bash
+recoup tasks status --run <run-id>
+recoup tasks status --run <run-id> --json
+```
+
 ### Global Flags
 
 All commands support `--json` for machine-readable JSON output.
 
+This command reference follows the source in this checkout. Run `recoup --version`
+and `recoup --help` to inspect your installed package; source changes alone do not
+establish that a new npm version has been published.
