Agent-written cache-regression RCA from Cloudflare, Vercel and Datadog

What it does

This workflow has an agent investigate a cache regression and write it up. Triggered by a detected origin-load spike, it gathers the Cloudflare cache-status breakdown, the suspect Vercel deploy and its changes, and correlated Datadog metrics, then reasons over the evidence to draft a structured root-cause analysis: what regressed, the likely cause, and recommended remediation. The draft lands in Notion for an engineer to confirm.

When to use it

Use it when you want a human-readable RCA started automatically while context is fresh, instead of reconstructing a timeline hours later. It fits teams who keep incident records in Notion and want the tedious evidence-gathering and first draft done for them.

How it works

  1. 1An origin-load-spike webhook fires from your detection layer.
  2. 2The agent pulls the Cloudflare cache-status and cache-hit ratio detail for the affected zone.
  3. 3It fetches the suspect Vercel deploy and its change summary.
  4. 4It queries Datadog for correlated latency and error signals around the spike.
  5. 5The agent synthesizes a root-cause narrative with timeline, cause, and remediation.
  6. 6It writes the RCA draft to a Notion incident page for human review.

Set it up

What you configure once, before turning it on.

  1. 1
    Connect CloudflareWorkers, Pages, R2, KV — the edge stack.
  2. 2
    Connect VercelDeploys, runtime logs, analytics.
  3. 3
    Connect DatadogMetrics, traces, log search.
  4. 4
    Connect NotionPages, databases, comments.
  5. 5
    Connect HTTP webhookTrigger any URL on agent actions.
  6. 6
    Set each agent's modelWe leave models unset so you pick the tier — fast + cheap, or top-quality.
  7. 7
    Tune it to your dataEdit the prompts, filters, and field mappings so it matches how your team works.
  8. 8
    Test, then turn it onRun once against a sample, confirm the output, then enable the trigger.
