How it runs

The automated pipeline, trigger to output.

  • TriggerDaily schedule fires before standup
  • ActionFetch 14 days of build durations from VercelVercelVercel
  • LogicGroup by project, compute rolling median and slope
  • LogicKeep only projects trending up past noise threshold
  • OutputPost ranked build-time digest to SlackSlack

What it does

Runs once a day, reads Vercel deployment build durations for every production project over a trailing 14-day window, and computes a per-project median plus the day-over-day and week-over-week slope. It posts a single Slack digest that ranks projects by how fast their build minutes are growing, so a slow regression surfaces before it becomes a 10-minute build.

When to use it

Use it when build times feel like they are slowly getting worse but no single deploy looks alarming. A daily digest catches gradual creep — a new dependency, an unbundled import, a growing test matrix — that a per-deploy alert would miss.

How it works

  1. 1A scheduled trigger fires every morning before standup.
  2. 2The flow calls the Vercel API to list deployments and their build durations across the 14-day window.
  3. 3A logic step groups by project, computes rolling medians, and ranks projects by upward slope.
  4. 4A second logic step keeps only projects trending up beyond a noise threshold.
  5. 5The flow posts a ranked digest to a Slack channel, with the worst offenders and their week-over-week delta at the top.

Set it up

What you configure once, before turning it on.

  1. 1
    Connect VercelDeploys, runtime logs, analytics.
  2. 2
    Connect SlackChannels, DMs, threads, mentions.
  3. 3
    Set each agent's modelWe leave models unset so you pick the tier — fast + cheap, or top-quality.
  4. 4
    Tune it to your dataEdit the prompts, filters, and field mappings so it matches how your team works.
  5. 5
    Test, then turn it onRun once against a sample, confirm the output, then enable the trigger.

Run this workflow in your colony.
