file-classification SKILL.md skillA
file-classification from cxcscmu/skilllearnbench is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add cxcscmu/skilllearnbench/file-classification@git:20260424.d50cf5aPins git:20260424.d50cf5a in mdr.lock. Pin the fingerprint instead.

Classify academic papers and documents into subject categories using keyword-based text analysis.
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
# File Classification by Subject ## Approach: Keyword Scoring For classifying documents into known categories, a keyword scoring approach is effective: 1. Define keyword sets for each category 2. Extract text from each document 3. Score text against each keyword set (count occurrences) 4. Assign document to highest-scoring category ## Keyword Sets for This Task - **LLM**: language model, transformer, attention mechanism, GPT, BERT, token, prompt, fine-tuning, NLP, neural network, deep learning, text generation, embedding, LLM, large language, reinforcement learning from human feedback, RLHF, instruction tuning, pretraining, machine learning - **Trapped ion / Quantum computing**: trapped ion, quantum computing, qubit, quantum gate, entanglement, quantum error, ion trap, quantum circuit, quantum algorithm, quantum processor, quantum information, Coulomb, motional mode, laser cooling, quantum simulation - **Black hole**: black hole, event horizon, Hawking radiation, singularity, gravitational, spacetime, general relativity, accretion, Schwarzschild, Kerr, entropy, holographic, AdS/CFT, cosmological, dark energy, dark matter …

How to install
mdr add cxcscmu/skilllearnbench/file-classification@sha256:df1952d1f2067ca1The line at the top of this page pins the label git:20260424.d50cf5a, 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.
