ab-v4 raw output capture on dashboard-search-filters-composite shows
minimax-m2.7 emitting <think>...</think> + 4 op_tool tags that fit
inside the 4096 default — its measured completion-token average for
this run was 697, well under the cap. So thinking-budget truncation
is NOT the actual root cause of minimax's lower multi-tool hit rate
(25% vs gpt+deepseek 50%); the real issues are instruction-following
(mixed Strategy A + B despite the explicit forbidance, invented
"canvas" parent_id placeholder).
Still doubling the cap defensively: composite multi-tool outputs can
chain 12-13 op_tool tags + thinking, and "fit easy" today doesn't
mean "fits headroom-free on a longer brief tomorrow." The bump is
free on the happy path (provider stops generating when done, doesn't
bill unused headroom) and only ever helps when the model would
otherwise hit a real ceiling.
Real follow-up for minimax: instruction compliance — the no-mix rule
needs to land harder than a single trailing sentence. Probably wants
the rule moved to top-of-prompt + a few-shot bad-example contrast.
Out of scope here; tracked under Phase 2 prompt design.
