Preconditions

• Explicit invocation approves one user-owned task. Arguments set its focus; otherwise recover the current objective from verified context.
• Require list_projects and create_thread. If unavailable, stop; do not substitute a shell command or Markdown file.

Build the continuity prompt

Write a self-contained prompt of roughly 2,000–4,000 Chinese characters or comparable size. Prefer smaller when links carry detail. Include:

• objective and first action;
• completed work and current state;
• decisions, constraints, and material rejected alternatives;
• authoritative files, plans, issues, commits, diffs, or URLs;
• verification performed and failures observed;
• remaining work, blockers, fragile state, and transient paths;
• relevant installed Skills.
