The mma-orchestrator skill is what the meta-tooling Tier 1/2 agents
load. The previous version was entirely built around the deprecated
scripts/mma_exec.py / claude_mma_exec.py bridge scripts — every
example used 'uv run python scripts/mma_exec.py --role tierN-X ...'
which was deprecated 2026-06-27 in favor of the OpenCode Task tool.
Rewrote the skill to use the OpenCode Task tool's subagent_type
parameter (tier3-worker / tier4-qa / tier1-orchestrator /
tier2-tech-lead) as the canonical mechanism, with explicit
deprecation notes for mma_exec.py.
Also updated: tool count (26 -> 45, now in src/mcp_tool_specs.py);
data locations (Ticket/Track/WorkerContext now in src/mma.py; the
src/models.py shim note).
The 8 mma_exec.py invocation examples in the previous version would
have caused Tier 2 Tech Lead agents to literally invoke deprecated
scripts. This is the highest-impact drift of the session — the user
explicitly said the deprecated invocation was wrong, and this skill
is what loaded the wrong pattern into agent context.
