## Tools (6)

- `export_list`: Download the generated email sequences for a COMPLETED list.

Only call this AFTER get_list_status shows processing_status = 'completed'.
If the list is not yet completed, you'll get a 409 error — poll first.
- `generate_batch`: Submit multiple leads for batch email sequence generation (ASYNC).

Returns IMMEDIATELY with a list_id. Processing runs in the background.
After calling this, poll get_list_status every 15-30 seconds until
processing_status is 'completed' or 'failed', then call export_list.

You must have a campaign_id first. Call list_campaigns if you don't have one.
- `generate_sequence`: Generate a personalized cold email sequence for ONE lead.

This is SYNCHRONOUS — the request takes 3-10 minutes because MachFive
researches the prospect and crafts unique emails. Do NOT retry if it
seems slow; wait for the response.

You must have a campaign_id first. Call list_campaigns if you don't have one.
If the request times out, use the returned list_id with get_list_status
and export_list to recover results.
- `get_list_status`: Check the processing status of a lead list.

Use this to POLL after calling generate_batch. Call every 15-30 seconds
until processing_status is 'completed' or 'failed'.
When completed, call export_list. When failed, submit a new batch.
- `list_campaigns`: List campaigns in the user's MachFive workspace.

CALL THIS FIRST before generate_sequence or generate_batch — you need a
campaign ID to generate emails. If the user hasn't specified a campaign,
call this and ask them to pick one.

Returns JSON array of campaigns with id, name, and created_at.
Use the 'id' field as campaign_id in generate calls.
- `list_lists`: List lead lists (batch jobs) in the user's MachFive workspace.

Useful for browsing past batches, checking what's in progress, or finding
a list_id to export. Results are ordered newest first.
