The brief the agent was handed
What it was asked for.
Audience
Backend and infrastructure engineers choosing one conference a year
The pitch
COLDSTART is a two-day single-track conference about what actually runs in production, with no sponsor talks and every speaker required to show real incident data. The page is a typographic poster: dates, city, and the speaker list at enormous scale.
Sections it decided on
- Type wall: name, dates, city
- Single track, stated as a rule
- Speaker list at scale with talk titles
- The no-sponsor-talks policy
- Schedule as a plain two-column grid
- Hallway track, workshops and the incident clinic
- Tickets, and the pay-what-you-can allocation
- Code of conduct and how it is enforced
The run
Fifty of these. About one developer day.
Same toolchain, fifty different briefs, no templates. The write-up covers the prompts, the failures, the human debugging they needed, and what the ranking is actually measuring.
