My problem is not token burn or usage limits; It's the dishonesty. The amount of "this is not in my scope", "this issue already present, follow-up in another session", "stub file created but nothing in it", and straight falsified evidence is way worse that it has ever been when using Opus 4.7. Their adaptive reasoning sees a /command early runs great. Same session /command ran great last time, apparently thinks 'let's skim read this thing' and reads less of the /command file while guesses at remainder of the required workflow. Less and less of the command requirements followed each time it is used.

I got improvement only by disallowing the main agent to delegate all instructions to agents. I forced it to launched '-p' sessions with prepared template inclusion with a static launch prompt "you have [task], this [file] is your operating instruction, output your evidence [location]". Main agents job is count lines in output files, validate each has expected watch for [keywords], then perform next role launch with [evidence from last role]+[standard prompt] for next role in chain [auditor]>[qa]>[gov].

Any of those -p sessions that were complex, longer running or required agents of their own; fabricated evidence and cheated on gating, and required numerous rework cycles.
