get_job to discover each trigger’s stable slug and reflection.paths. Never assume an automatic trigger is trigger-1. Mustache renders only the firing trigger’s context: manual has prompt and data; schedule currently has occurredAt, externalId and metadata.timezone; provider context contains prepared delivery fields (Linear issue, ClickUp task); terminal lifecycle currently has sourceJobId, sourceRunId, state, completedAt; edited has source_job_id, event, edited_at. Current reflection still describes older snake_case terminal fields: use the persisted run context as the authority.
Missing/null scalar paths become empty text. Objects and arrays interpolate as compact JSON; array order is preserved and object keys sorted. Double braces preserve plain-text URLs, quotes, Markdown and code; triple braces are also supported. Sections use original context truthiness and array iteration. There are no global parameter defaults/overrides.
After creating an automatic trigger, read its returned slug, then safely replace the full configuration to reference that slug. For example {{trigger-2.issue.title}} only works if that is the actual Linear trigger. Verify the rendered prompt and complete context with get_run. See the full context contract.
