Nightly Coda wiki freshness grader

Every night, embeds each Coda doc page and scores it for staleness against the current source-of-truth, then writes a freshness grade and reason back onto each page.

What it does

Runs a nightly sweep of your Coda workspace, embeds every page, and grades each one on how stale its content has become relative to the authoritative source data. Each page gets a freshness score (0-100), a plain-English reason, and a last-graded timestamp written back into Coda so editors can see at a glance which docs are decaying.

When to use it

Use it when your team's wiki has grown past the point where humans can manually audit freshness, and outdated runbooks or specs are causing real mistakes. Best for orgs that keep a structured source of truth (a Postgres table, product spec, or canonical doc) that wiki pages are supposed to reflect.

How it works

  1. 1A nightly schedule fires the run.
  2. 2The flow pulls every page from the target Coda doc.
  3. 3Each page body is embedded with OpenAI and compared against embeddings of the source-of-truth records.
  4. 4A grading step computes a staleness score from semantic drift plus age since last edit.
  5. 5The score, reason, and timestamp are written back to a freshness column on each Coda page.

Set it up

What you configure once, before turning it on.

  1. 1
    Connect CodaDocs, packs, automations.
  2. 2
    Connect OpenAIModels, embeddings, files.
  3. 3
    Connect PostgresAny Postgres URL — query, write, migrate.
  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.
