vector-store-operations from amey-thakur/ai-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Run a vector index in production, covering dimensions, filtering, updates, and reindexing when the embedding model changes. Use when semantic search is live and must stay correct as data and models change.
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
# Vector store operations A vector index is a derived structure tied to a specific embedding model. The operational realities that surprise teams are that filters interact badly with approximate search, updates are not free, and changing the model means rebuilding everything. ## Method 1. **Pin the embedding model per index.** Vectors from different models are not comparable, so a model change is a full reindex rather than a rolling update (see embeddings-selection). 2. **Understand your filtering model.** Pre-filtering and post-filtering behave very differently with approximate search, and post-filtering can return far fewer results than requested. 3. **Store metadata alongside vectors.** Filters on source, date, and permissions need to be evaluated in the index rather than after retrieval (see realtime-permissions). 4. **Plan updates and deletions explicitly.** Some indexes handle deletion by tombstoning and degrade until compacted, which is an operational task rather than an automatic one. 5. **Build into a new index and swap.** Reindexing in place leaves the system serving inconsistent results during the rebuild (see search-indexing-pipeline). …

How to install
mdr add amey-thakur/ai-skills/vector-store-operations@sha256:0c1d1c7450b6f6f8The line at the top of this page pins the label git:20260728.fe84bd4, 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.
