Use this skill when an agent needs to compute a substrate hot-path primitive — SimHash, Hamming distance, OR-reduce, bitwise combinators, Fingerprint256 construction, HammingNN top-K nearest neighbors, BitField bitmap extraction, or a SHA-256 hash. These are byte-identical Swift+Rust implementations behind a conformance-gated CRC. Trigger this skill whenever an agent is about to hand-write any of those operations, or use any bit operation on a Fingerprint256. (The AuditGate write gate lives in SubstrateLib and HLCGenerator in SubstrateTypes — see their skills.) The skill redirects to the existing implementation and prevents re-invention drift the conformance harness would catch in CI.
Use this skill when an agent needs cold-path or dreaming-driven algorithms — matrix decay, moment summary OR-reduce, Bradley-Terry online weight update, anomaly z-score, information theory (entropy / MI / KL), temporal compression rollups, partial-state recall scoring, FFT for rhythm analysis, NMF factorization, eigenvalue centrality (keystone scoring), audit-log fold for state projection or as-of reads, tier-contribution federation aggregate, or pairing handshake to mint shared hyperplane seeds. All 15 are conformance-gated Swift+Rust byte-identical. Trigger this skill any time an agent is about to write one of those, run a recall query that needs as-of state, compute a population-stat update, or anything dreaming-daemon-shaped. Redirects to the existing implementation.
Use this skill when working with substrate row shape — declaring, serializing, or holding a row without computing on it. Covers Fingerprint256 (the 256-bit four-block container), HLC (hybrid logical clock value), Row / RowLite, LatticeAnchor, AuditEvent (struct shape), MatrixF/C/O/T (storage containers), layout constants (BlockMask, RowBitmaps, BitVector216), TimeRange, and substrate enums (MutationKind, PairingScope, GeneratedByClass, NounType, RowStateValue). Trigger this whenever an agent is about to declare a substrate struct field, define a CloudKit record, write a wire-format encoder, or stub out an audit event. Do NOT trigger for algorithms — those belong to SubstrateKernel or SubstrateML.
Building product features that USE EngramLib (Swift or Rust). Trigger when product code needs similarity, nearest-neighbor, radius search, or engram aggregation. Trigger on phrases including "EngramLib", "Engram", "find nearest", "Hamming similarity in app code", "recall similar", "build a feature on the substrate", "EngramLib.Session", "engram_kit". Do NOT trigger on kernel implementation, decision records, or substrate engineering maintenance — that is the substrate-engineering skill.
