handoff chains analysis
summary
extracted 1,239 spawn edges from message content (patterns: “from thread T-xxx”, “read_thread…T-xxx”). found 175 distinct root chains with max depth of 73 levels.
key stats
| metric | value |
|---|---|
| total spawn edges | 1,239 |
| distinct root chains | 175 |
| max chain depth | 73 |
| avg chain size | 8.84 threads |
| threads in chains | 1,361 |
chain outcome distribution
threads participating in spawn chains show different outcome patterns than overall:
| status | count | % |
|---|---|---|
| RESOLVED | 1,068 | 78.5% |
| COMMITTED | 153 | 11.2% |
| UNKNOWN | 126 | 9.3% |
| EXPLORATORY | 6 | 0.4% |
| HANDOFF | 3 | 0.2% |
| FRUSTRATED | 5 | 0.4% |
corrected 2026-01-09: prior analysis miscounted spawned subagent threads as HANDOFF. most were actually RESOLVED (spawn instructions to subagents, not true handoffs).
depth distribution
most chains are shallow (2-3 levels), but some marathon sessions go deep:
depth 2: 66 chains ████████████████████
depth 3: 21 chains ██████
depth 4: 23 chains ███████
depth 5: 15 chains ████
depth 6: 16 chains █████
depth 7: 9 chains ███
...
depth 33: 3 chains █
depth 48: 1 chain
depth 55: 1 chain
depth 73: 1 chain (@concise_commander marathon)

observations
-
@verbose_explorer’s parallelization strategy: spawns many parallel branches (size >> depth), indicating coordinated multi-agent work
-
@concise_commander’s marathon debugging: goes deep rather than wide (depth 73 on interface design), suggesting iterative refinement over handoffs
-
chain resolution rate: 78.5% RESOLVED — spawn chains are highly effective at solving problems
-
orphan detection: some chains (like T-019b31c3) have missing metadata - possibly threads that were deleted or corrupted
-
optimal chain depth: chains with depth 4-7 have highest resolution rates. beyond depth 10, resolution rate still high but complexity overhead increases
