Shadowing Risk

A tool whose purpose is substantially covered by a sibling that is materially cheaper to invoke. Both can score well alone; an agent that can reach the answer either way tends toward the cheaper call, and when the dearer tool is the authoritative one the agent presents an answer it assembled itself. A deterministic prefilter proposes at most one candidate pair per tool and the coherence evaluation confirms whether the purposes genuinely overlap.

None. The flag is published beside the coherence score rather than folded into it, and the four coherence dimensions are instructed to ignore invocation cost.

all flags, or the specification.
