- ponderNewhashgraph-online/awesome-codex-pluginsConvergent multi-pass deliberation and code review ledger that enumerates units, grades every unit against a lens rubric, runs four-perspective deliberation (Skeptic, Builder, Dreamer, Empath), records append-only finding deltas, verifies phantom-unit removals across all historical paths, and enforces 1.00 coverage and zero-churn convergence before stopping. Use when the user says "ponder <anything>" ("ponder the UI", "ponder our error handling", "ponder this PR"), "run a ponder audit", "grade every unit with the ponder ledger", "run four-voice Skeptic/Builder/Dreamer/Empath deliberation", or asks for a coverage-gated multi-pass lens audit across files or screens where stopping early would miss units.

- data-formshuytieu/COG-second-brainPick the right way to represent a dataset so a reader gets the finding in three seconds — a catalog of 20+ chart and diagram forms with when-to-use and failure modes, plus the encoding decisions that make any of them readable (takeaway headline, direct labels, kill the axis, highlight-and-mute, show the caveat).
