New productivity/andreessen plugin — a Marc Andreessen-mode operator that
pressure-tests ventures/ideas/features/bets through his documented frameworks
(market > team > product; product/market fit is the only milestone; bias to
build) and runs his 3x5-card + Anti-Todo daily routine. Built as the
Andreessen-lens counterpart to a founder-operating-system plugin.
Runs on the user-supplied anti-sycophancy operating prompt, preserved verbatim
in references/operating_prompt.md (counterargument first, no premise validation,
no disclaimers, explicit confidence levels, no capitulation without new
evidence). The second emphasis block is operationalized as a posture-mapping
table so each instruction changes behavior rather than sitting as decoration.
Ships 3 stdlib-only deterministic tools (market_first_evaluator with a hard
sub-4 market kill gate, pmf_signal_scorer with the Sean Ellis 40% gate,
anti_todo_card enforcing the 3-5 cap), 4 references each citing 5-7 sources with
explicit confidence levels on every Andreessen attribution, cs-andreessen agent,
/cs:andreessen + /cs:pmf-check commands, and a worked 3x5-card asset.
Registered in marketplace.json + .codex skills index (productivity 5 -> 6).
.codex review/run/status symlinks reflect the sync generator's standard
collision resolution on the current tree.
