security-fix-oracle skillA
security-fix-oracle is agent-read markdown (skill) from lu1sdv/skillsmd: Use when turning a real project's git history into a labeled, enriched, leakage-free security-fix dataset ("oracle") for a vulnerability classifier, rule-authoring feed, or risk-prioritization model. Triggers: "mine commits for security fixes", "build a vuln dataset / training corpus from git history", "label commits by CWE / vuln category", "SZZ", "blame who introduced the vulnerability", "vulnerability-introducer attribution", "skill-gap analysis", "CVSS scoring of commits", "diff-verified gol.
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Security-Fix Oracle — mining git history into a labeled vuln dataset A reproducible pipeline + runnable **harness** for converting a project's commit history into a quality-tiered, leakage-aware dataset of security fixes, enriched with **CVSS 3.1** scores and **SZZ vulnerability-introducer attribution**. Built and validated on `gitlab-org/gitlab` (189k commits → 18,202 security-relevant → 1,018 diff-verified gold + 204 non-Ruby confirmed; CVSS over 18,060 rows; SZZ over 13,643 diffed rows). The methodology is repo-agnostic; the harness constants point at the GitLab build and are meant to be re-pointed. ## What it produces A single Parquet (one row per commit SHA) with: - **labels**: `category` (vuln-class taxonomy term), `cwe[]`, `quality_tier` (gold/weak) - **features**: `subject`, `body`, `diff` (the fix patch), `sink`, `tainted_input`, `language` - **enrichment**: `cvss_score`/`cvss_vector`/`cvss_severity`, `vuln_class_cwe[]` - **attribution** (optional sidecar column, PII): `szz_introducers`, `szz_primary_introducer`, … - **quality signals**: `is_security_fix_regate`, `label_disagreement`, `near_dup_subject_hash` …

How to install
mdr add lu1sdv/skillsmd/security-fix-oracle@git:20260922.755d461mdr add lu1sdv/skillsmd/security-fix-oracle@sha256:17939b5e9cedccfdPin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
