# Automations
|
|
|
|
The `automation` tool admits schedules, domain events, context conditions, and shell scripts.
|
|
The ledger stores durable deadlines and fire counts.
|
|
A fire creates its subscriber deliveries in the same transaction.
|
|
Each delivery uses a stable request id, so a restart does not duplicate the subscriber input.
|
|
Prompt runs use owned subagent conversations.
|
|
|
|
## Definitions and scripts
|
|
|
|
Each automation occupies `/src/sausage/automations/A<n>/` in the world.
|
|
The tool writes `automation.json` there as a readable copy of its definition.
|
|
The durable ledger remains authoritative.
|
|
The extension does not import manual changes to this copy.
|
|
Deletion retains the files.
|
|
|
|
A script uses `script.sh` in that directory.
|
|
If the file exists, the extension executes it with world `sh`.
|
|
Otherwise, a watcher writes it from the `ask` request before execution.
|
|
The watcher inherits the creator's agent configuration.
|
|
The script receives a one-hour timeout.
|
|
The host cancels execution when the task aborts.
|
|
|
|
Only stdout lines with `FIRE` trigger deliveries.
|
|
An optional message follows `FIRE`.
|
|
Stderr lines never trigger deliveries.
|
|
`DONE` takes effect after a successful exit.
|
|
The extension retains a bounded log in `log`.
|
|
Script tasks deduplicate their fire sequence across restarts.
|
|
External script effects can repeat after a crash.
|
|
|
|
## Credentials
|
|
|
|
The conversation that creates an automation remains its execution conversation.
|
|
Every script launch uses `host.chain(creator)`.
|
|
The host delegates to `conversationChains` in `host/js/environment.ts`.
|
|
The host appends the branch starter's chain after the ownership or fork ancestry.
|
|
The host removes duplicate ids without changing their order.
|
|
Subscribe and unsubscribe change notification recipients only.
|
|
They never change the execution conversation.
|
|
Built-in automations without a creator use an empty chain.
|
|
No secret value enters a definition, script environment, or watcher prompt.
|
|
|
|
## Triggers
|
|
|
|
Schedules accept `cron`, `at`, `in`, and `every` forms.
|
|
The five imported schedule cases verify IANA zones, leap days, and daylight-saving transitions in V8.
|
|
Events use the durable event service and its reactor cursor.
|
|
Conditions use measured prompt tokens and the model's context window.
|
|
A decrease of ten percentage points below the threshold re-arms a condition.
|
|
The cooldown starts with a condition fire, not a manual fire.
|
|
For `idleFor`, admitted conversation inputs reset the idle period.
|
|
|
|
## Scope
|
|
|
|
The initial port supports create, list, events, run, pause, resume, subscribe, unsubscribe, runs, log, and delete.
|
|
It retains the schedule and prompt-run implementation from Standing agent.
|
|
It replaces native process groups with host Exec.
|
|
Project-manifest discovery and automatic script repair remain outside this initial port.
|
|
Credentials use grants, not named secret files.
