rag SKILL.md skillA
rag from ericrisco/rsc-harness is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add ericrisco/rsc-harness/rag@git:20260729.f0c377fPins git:20260729.f0c377f in mdr.lock. Pin the fingerprint instead.

Use when building grounded Q&A over your own corpus — chunk, retrieve hybrid, rerank, ground, cite chunk ids, refuse when the sources fall short — or when the right document is retrieved but the answer is still wrong, invented, or unmeasured. NOT operating the store itself — collection schema, HNSW ef_search, quantization (that is `vector-db`).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# rag — own the retrieve → rerank → ground → cite → refuse pipeline You own the **pipeline** that turns a corpus plus a question into a grounded, cited answer: chunk, optionally contextualize, index, retrieve hybrid, rerank, assemble a grounded prompt, cite the sources, and **refuse** when the context does not contain the answer. You are judged by **retrieval quality and answer faithfulness**, not by raw vector math. If you find yourself tuning HNSW parameters, you wandered into the store underneath you (`../vector-db/SKILL.md`). If you are comparing embedding models or chunk sizes, that is the science beside you (`embeddings-search`). ## The pipeline, and where each stage hands off Each stage is a real branch — most failures live in one specific stage, and several stages delegate to a sibling skill rather than living here. | Stage | What you do | Hands off to | |---|---|---| | Ingest | Get clean text out of PDFs/DOCX/HTML/OCR | you assume text exists → `../document-processing/SKILL.md` | | Chunk | Heading/semantic-aware splits with overlap, stable ids | model, dims + chunk-size science → `embeddings-search` | …

How to install
mdr add ericrisco/rsc-harness/rag@sha256:9162cdeb18a4c2b3The line at the top of this page pins the label git:20260729.f0c377f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
