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. doc-diff-checker — 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. project-instructions-updater — 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 config/sync-source.md at your source-of-truth doc (Doc ID or file path) and the target Claude Project ID.
3. Run the starter prompt in starter-prompts.md once to do an initial full sync and establish the baseline version.
4. Schedule automation-prompt.md to check for changes on your preferred cadence (hourly is typical for actively-edited docs).
