Sas94 Skill

sas94-skill

A [Claude Code](https://docs.anthropic.com/en/docs/claude-code) skill for writing, reviewing, and debugging SAS 9.4 code with AI assistance.

SAS 9.4 is the daily driver for biostatisticians, health-services researchers, and pharma/claims analysts, yet SAS is underrepresented in LLM training corpora. This skill distills rules and idioms from MIT-licensed sources (`sasjs/lint`, `sasjs/core`) plus hand-transcribed SAS-programmer pitfalls (GWU data-mining curriculum), and routes Claude Code to topic-specific reference files on demand.

**Status:** `v0.0.1` pre-release. Reference content is organized as per-topic atom directories under `references/`, with each atom covering one concept (e.g. `references/data-step/merge.md`, `references/macros/scope-and-quoting.md`). Atoms are populated across both REQUIRED sections (Overview, Critical Rules, Canonical Idioms, Function/Statement Quick Ref, See Also) and OPTIONAL sections (Silent Pitfalls, Anti-patterns). See [`docs/coverage-matrix.md`](docs/coverage-matrix.md) for per-file status.

What This Skill Does

When activated, Claude Code can:

• Translate study descriptions into idiomatic SAS 9.4 (DATA step, PROC SQL, macros, PROC FREQ/MEANS/LOGISTIC, hash tables, ODS)
• Catch silent-failure patterns before code ships — MERGE overwrite, LAG-inside-IF, missing retain on accumulators, macro-quoting errors, PROC APPEND shape mismatches, and more
• Enforce the 15 rules from sasjs/lint v2.4.3 covering macro definition, file headers, line formatting, and source hygiene
• Apply sasjs/core macro patterns — positional-required + keyword-optional signatures, %local discipline, iftrue= guards, /*/STORE SOURCE*/ registration
• Route to topic-specific reference files for deep dives
