renorm

Force-invoke renorm:derivation to start a derivation ledger. Optional argument: the observable target.

Force-invoke renorm:paper-analysis on a specific paper. Argument: arXiv ID, DOI, or local PDF path.

Force-invoke renorm:core to apply tagging + grounding discipline. Optional argument: a specific claim to interrogate.

Use when the user is making, asking about, or evaluating a research-level theoretical physics claim or comparison — about a specific system, mechanism, methodology, recent result, or unexplored regime. Applies to correlated systems, condensed matter, many-body physics, and adjacent topics. Skip for textbook recall (e.g., 'what is BCS pairing'), code/tooling, casual conversation, or algebra inside an active derivation.

Use when actively performing a theoretical derivation — including exploratory expansions and back-of-envelope estimates: writing equations, applying approximations (perturbation, mean-field, saddle-point, downfolding), expanding to a given order, computing a spectrum or response. Ledger weight scales with derivation complexity — short exploratory derivations get a lightweight 3-line ledger; full derivations get the 6-field form. Not for discussing existing derivations from a paper (use renorm:paper-analysis) or pure conceptual comparison (use renorm:core).

Use when initializing a new scientific computing package in Python, Julia, or C++. Picks the appropriate template directory based on user's request. Generates a working package skeleton with reproducibility conventions (RNG seeding, units in comments, type hints) consistent with the user's rules in ~/.claude/rules/.

Use when summarizing, analyzing, or extending claims from a specific paper (arXiv ID, DOI, or local PDF). Applies a quote-before-claim discipline: every assertion about the paper's content must be backed by a direct quote, equation reference, or figure reference. Not for general 'what does field X say' questions, which go to renorm:core; not for actively performing your own derivation, which goes to renorm:derivation.
