Detect changed specs between manual revisions and alert affected teams

When a new manual revision is indexed, it diffs key specs against the prior version and posts a 'spec changed' alert to Slack summarizing what changed, the old vs new values.

What it does

Compares each newly ingested manual revision against the version it replaces, uses an LLM to extract and align the technical specs, and flags any value that changed. It then sends a structured alert so techs do not keep working from outdated torque, voltage, or clearance numbers.

When to use it

When a manufacturer ships a revision and you need to know immediately which specs moved, not just that a new PDF exists. Critical for safety-sensitive or warranty-bound equipment where a stale spec causes rework.

How it works

  1. 1The reindex workflow marks a manual version as superseded, firing this trigger.
  2. 2The flow pulls the old and new page chunks for the same equipment from Supabase.
  3. 3OpenAI extracts comparable spec key-value pairs from both revisions and aligns them.
  4. 4A logic step keeps only specs whose values actually changed, attaching old value, new value, and page.
  5. 5If any change is found, a formatted 'spec changed' alert with a page link is posted to the Slack ops channel.

Set it up

What you configure once, before turning it on.

  1. 1
    Connect SupabaseTables, auth, storage, edge functions.
  2. 2
    Connect OpenAIModels, embeddings, files.
  3. 3
    Connect SlackChannels, DMs, threads, mentions.
  4. 4
    Set each agent's modelWe leave models unset so you pick the tier — fast + cheap, or top-quality.
  5. 5
    Tune it to your dataEdit the prompts, filters, and field mappings so it matches how your team works.
  6. 6
    Test, then turn it onRun once against a sample, confirm the output, then enable the trigger.
