Helios MTP acceptance analysis skill
Use this skill for MTP, speculative decoding, drafter, assistant model, verify/rollback, accepted tokens, or block-size tuning work.
Required discipline
- Do not make random MTP fixes before trace evidence exists.
- MTP output must match non-MTP native output at temperature 0.
- Record draft token, target token, top-k when feasible, accepted count, rollback, verify latency, shared KV shapes, and position offsets.
- Compare short prompts and real-context prompts separately.
- Treat acceptance improvement and net speedup as separate metrics.
- Keep MTP disabled by default unless a Goal explicitly accepts a gated default change.
Evidence to return
- Acceptance by workload family.
- Accepted tokens per verify pass.
- Exactness result.
- Speedup/slowdown after load and prefill are separated.
- Top likely root cause if acceptance is poor.
