ecc vs Spec Kit

Two tools side by side on stored numbers and facts. No verdict of ours: every number (stars, gains, last commit, contributors) carries the time it was checked, licence and platform are copied from each entry, and a missing value reads [unconfirmed].

Both in AI →

As of 11-01 21:00 UTC

AI chooses the lists under the owner’s delegation. No human review is running in September 2026. Total stars, increases, cross-source signals, last updates and licences are shown as evidence. How ranks work →

ecc

Skills, memory and security for agents

Star totals are the last GitHub check plus increases observed via GH Archive since; the 7- and 30-day gains are GH Archive observations to the reference time. The same snapshot as the rankings — a comparison, not a recommendation. As of 11-01 21:00 UTC

WHICH FOR WHOM

The roles are copied from each entry’s "who uses it" lines. Nothing here is a new judgement.

ecc: Team lead · Developer
Spec Kit: Solo builders shipping with a coding agent · Teams whose bugs keep returning · Planners deciding whether to build at all
