autonomous-roundtable
DEPRECATED: This skill has been absorbed into the develop skill. Use develop instead.
The capabilities of autonomous-roundtable (project decomposition, roundtable gating,
reflexion on ITERATE) are now available through develop's dialectic_mode and
token_enforcement preferences. Set dialectic_mode to "roundtable" in Phase 0.4
for equivalent behavior.
