name	chain-link
description	Save a work checkpoint to preserve context for multi-session projects. Use when pausing work on a feature, completing a milestone, or before ending a session.

Chain Link - Save Work Checkpoint

Save your current work context as a chain link for later retrieval.

Usage

/chain-link [chain-name] [slug]

Instructions

1. Gather Context - Analyze the current session:

   • What was accomplished
   • Key technical decisions made
   • Code changes with file paths
   • Unresolved issues or blockers
   • Next steps

2. Generate Chain Content - Structure as XML:

<chain-link>
  <summary>Brief overview of work done</summary>

  <completed>
    <item>Task or feature completed</item>
    <item>Another completed item</item>
  </completed>

  <code-changes>
    <file path="src/auth.rs">Added JWT validation middleware</file>
    <file path="src/routes.rs">New /login endpoint</file>
  </code-changes>

  <decisions>
    <decision reason="Performance">Used Redis for session storage</decision>
    <decision reason="Security">JWT tokens expire after 1 hour</decision>
  </decisions>

  <issues>
    <issue status="blocked">Rate limiting not implemented yet</issue>
    <issue status="investigation">Memory leak in connection pool</issue>
  </issues>

  <next-steps>
    <step priority="high">Implement rate limiting middleware</step>
    <step priority="medium">Add refresh token support</step>
  </next-steps>
</chain-link>

3. Save via MCP - Call tinymem_chain_link:
   • session_id: from TINYMEM_SESSION env
   • chain_name: provided or infer from task context
   • slug: provided or generate from summary (kebab-case)
   • content: XML structured content above

Examples

User: /chain-link auth-feature jwt-middleware → Saves checkpoint with chain "auth-feature", slug "jwt-middleware"

User: /chain-link → Ask user for chain name, auto-generate slug from work summary
