The whole point of the n-tools-per-element design is stability for weak
models in the BUILT-IN AGENT path (MiniMax / GLM / Kimi). But empirically
no element tool was firing on that path — the model emitted raw JSONL
and bypassed every `<op_tool>` strategy.
Root cause: when `elementToolsEnabled` is true, the prompt mixed two
incompatible output-format instructions:
- jsonl-format / jsonl-format-simplified — early in the prompt, leads
with `CRITICAL: Output ONLY ```json. Do NOT use [TOOL_CALL] or
{tool => ...} syntax.`
- ELEMENT_TOOL_OUTPUT_FORMAT — appended at the end, says `Respond
with one or more <op_tool> tags, nothing else.`
Weak models anchor on the early CRITICAL ("Do NOT use tool calls"),
read `<op_tool>` as a forbidden tool-call form, and silently fall back
to raw JSONL. Result: every brief on basic tier with element tools
enabled bypassed the whole element-tool surface — which is the opposite
of the design intent.
Fix: when `elementToolsEnabled` is true, drop both `jsonl-format` and
`jsonl-format-simplified` from `resolvedSkills`. ELEMENT_TOOL_OUTPUT_FORMAT
becomes the sole output-format instruction. Content rules (schema /
layout / text-rules / overflow / icon-catalog / elements) stay loaded.
This was P5/ab-v8's blind spot: the test harness either ran on standard
tier (no jsonl-format-simplified swap) or didn't observe `<op_tool>`
emit rate directly, so the conflict masked real-world failure on basic
tier in the built-in agent path.
