Implementation notes
- Use this Developer Guide doc as a navigation page first: the local clone mirrors the source structure and links each heading back to the authoritative upstream section.
- Primary decision areas: Cached system prompt layers, Concrete example: assembled system prompt, Persistent Memory, User Profile, Skills (mandatory). Read those source anchors before changing installs, credentials, automation, or runtime configuration.
- Useful search signals for this doc: prompt, assembly, deliberately, separates, cached. These are derived from the public title and summary so the clone remains lightweight.
Decision table
Use when you need orientation for prompt assembly before applying exact upstream commands.
Open the source anchor for Cached system prompt layers and confirm platform-specific requirements before changing configuration.
Use the upstream page as the authority for current syntax, release changes, and security-sensitive steps.
Verification checklist
- Use this page to orient yourself within Developer Guide, then open the linked source page for exact current syntax.
- Start with the source section for Cached system prompt layers; do not rely on the local summary for commands or secrets.
- Check platform, install method, provider, and credential assumptions before changing a real environment.
- Review the source section for Concrete example: assembled system prompt if the page involves setup, automation, messaging, or runtime behavior.
- After applying anything from the source, run the smallest relevant smoke test before widening scope.
Risk notes
Keep human review before sending public posts, customer messages, trading instructions, or team notifications.
Check filesystem, shell, browser, repository, and server permissions before granting the agent write access.
