ChatDev holds an Evidaxis momentum score of 49.5 of 100 on methodology m4, snapshot 2026-10-10, measured within the Coding Agents cohort (n = 20). Axis coverage: 1 of 3 axes measurable. Gate: not computable — 1 of 3 axes measurable

Derived signals

second-order reads, computed from the published series

Three signals ship when the commit series is statistically sufficient; the rest are held in a reserved state until the data supports them. A reserved signal shows its reason, never a fabricated number. How these are computed.

recency-weighted swing trailing 13-week vs prior 39-week log-slope ratio -5.92, regime recent slope sign differs from prior window. prior slope +0.004, recent slope -0.023 per week. +0.004prior 39w-0.023recent 13w-5.92×

points

Weekly commits over the past year, reconstructed from git history (GitHub commit_activity). This is reconstructed, not a point-in-time capture. Evidaxis captures the Type-2 signals (watchers, issues, dependents) live and never backfills them; those are the moat.

Measurement states

ChatDev is under weekly measurement. History: 14 weekly observations; minimum 4. Development velocity axis: measured. Citation axis: insufficient source coverage (source returned too few observations). Direct-dependents axis: no admitted own package; not measured. Gate: not computable — 1 of 3 axes measurable
