asymmetric seed <id> [options]
Seeds a running clone into a known starting state. Fixtures apply deterministic SQL directly; --ai generates realistic data and creates it through the clone’s REST API. For the conceptual difference, see Seeding.

​
Arguments

ArgumentRequiredDescription
<id>yesThe clone id, e.g. slack-a1b2.

​
Options

OptionDescription
-f, --fixture <name>Named fixture pack (deterministic SQL), e.g. acme-corp.
--aiGenerate AI data using the template’s defaults. Needs ANTHROPIC_API_KEY.
--jsonOutput the seed result as JSON instead of the human summary.
You must pass at least one. With neither, the command prints Nothing to seed. Pass --fixture <name> and/or --ai. and exits 1.

​
Examples

Deterministic fixture: 
asymmetric seed slack-a1b2 --fixture acme-corp
AI-generated data: 
asymmetric seed slack-a1b2 --ai

  ✓ seeded slack-a1b2  (ai: 20 (0 rejected))
Both at once (fixture backbone + AI on top): 
asymmetric seed slack-a1b2 --fixture acme-corp --ai

  ✓ seeded slack-a1b2  (fixture: 150 rows · ai: 78 (3 rejected))
    ! signup alice-0: 409 conflict
    ! message: 400 invalid channel
Warnings (prefixed !) are best-effort — rejected records don’t fail the seed. Up to five are shown.

AI seeding details

  • Model: claude-haiku-4-5.
  • Auth: reads ANTHROPIC_API_KEY from your environment.
  • Default brief: “a small, fast-moving software startup.”
  • Default volume medium: 6 users, 4 channels, 20 messages. See the volume table.
  • Data is created via real signup → workspace → channels → messages, so auth and referential integrity hold.

​
Seed on spin

To seed at create time instead, pass --seed to spin: 
asymmetric spin slack --seed acme-corp

​
Reset replays it

The last seed is recorded on the clone and re-applied automatically by reset.

Errors you might see

ErrorCause
CLONE_NOT_FOUNDNo clone with that id.
LLM_UNAVAILABLEAI seeding failed (model error, parse error, or missing API key). Retry.
SEED_VALIDATIONGenerated records were rejected by validation.
