Key answer
A new conversation needs enough current state to continue: goal, authoritative artifact, constraints and starting point. Do not copy the entire history unnecessarily, but “continue last time” is insufficient.
Full explanation
Automatic inheritance depends on the product. Claude's history search has project-scope restrictions and separate project memories; OpenAI distinguishes ChatGPT and local Codex memory. Confirm that important conventions and latest files are available in the new conversation; an old chat's existence does not establish inclusion. Claude scope, OpenAI memory
Reprovide especially:
· Goals and acceptance criteria: audience, deliverable and mandatory requirements.
· Current artifacts and material: latest version, accessible files/links, key terms and necessary original text.
· Confirmed decisions: choices, reasons and superseded approaches/rules.
· Progress and remaining work: actual completion and verification, gaps and next action.
For tasks with action permissions or resource limits, include still-valid authorization, budgets and stopping conditions. Add unconfirmed ideas, old drafts or failed attempts only when they prevent repeating mistakes.

Anthropic's context-engineering practice uses compaction and persistent notes to retain key state while rereading material as needed. For daily work, adapt this as a short handoff plus latest artifacts and necessary sources. See B017 for details. Engineering explanation
