Explicit Identity Across Boundaries

Never rely on "latest" or "current" when crossing process or async boundaries.

Pattern

Pass explicit identifiers through the entire pipeline. "Most recent" is a race condition.

DO

  • Pass 
    --session-id $ID
    when spawning processes
  • Store IDs in state files for later correlation
  • Use full UUIDs, not partial matches
  • Keep different ID types separate (don't collapse concepts)

DON'T

  • Query for "most recent session" at execution time
  • Assume the current context will still be current after await/spawn
  • Collapse different ID types: 
    • session_id
      = Claude Code session (human-facing)
    • root_span_id
      = Braintrust trace (query key)
    • turn_span_id
      = Braintrust turn within session

Example

typescript
// BAD: race condition at session boundaries
spawn('analyzer', ['--learn'])  // defaults to "most recent"

// GOOD: explicit identity
spawn('analyzer', ['--learn', '--session-id', input.session_id])
