Claude Projects Sync AI Agent

What this agent does

Claude Projects drift the moment two people edit instructions in two places — someone updates the source-of-truth doc, forgets to paste it into the Project, and now the model is running on stale context. This agent keeps a Claude Project's custom instructions permanently in sync with a single source-of-truth document, so the doc is the only place anyone ever needs to edit.

1. stage-1-change-detection — compares your source-of-truth doc (Google Doc, Notion page, or local Markdown file) against the last-synced version, and detects whether a meaningful change has happened.
2. stage-2-sync-apply — when a diff is found, reformats the doc content to fit Claude Project's custom-instructions field constraints and updates it via the Claude API/Console, then records the new synced version.

Every run logs whether a sync happened and a short diff summary, so you can see exactly what changed and when.

Requirements

• A Claude Project with API-manageable custom instructions (Claude API access — not required to be Claude Max, but you do need API access for the update step).
• Your source-of-truth doc accessible via gog (Google Docs) or a local/synced Markdown file.
• Works on OpenClaw (scheduled trigger + gog for Docs access) or Claude Code run manually/via cron.

Setup

1. Unzip the package into your workspace, keeping the folder structure intact.
2. Point the sync at your source-of-truth doc (Doc ID or file path) and the target Claude Project ID.
3. Run the starter prompt once to do an initial full sync and establish the baseline version.
4. Schedule it to check for changes on your preferred cadence (hourly is typical for actively-edited docs).

What you get

• Your Claude Project's custom instructions kept automatically in sync with a single source-of-truth doc
• Change detection that only updates the Project when a meaningful diff is found, not on every check
• A synced-version record so you always know what state the Project is running on
• A log of every sync attempt with a short diff summary, so you can see exactly what changed and when
• Setup that works on OpenClaw or Claude Code with your existing Google Docs/Notion access
