zvec

zvec is a cursor rule for Cursor from alexqem/zvec-tool. It costs 0 tokens per session (765 once invoked), scanned A, original, MIT.

A command-line tool for finding relevant project documents by meaning rather than exact words. It searches an indexed knowledge base, such as documentation, regulations, and business-process notes.

In plain words
What is it for?
Use it to locate related documentation, regulations, process descriptions, or context before changing project configuration; use ordinary grep for code and configuration files.
Why use it?
A normal text search may miss documents that use different wording, while searching source code with this tool is outside its intended scope.

Cursor rule for Cursor

Written for Cursor: installed under .cursor/.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is node zvec-tool/zvec.mjs search "<query in RU or EN>" --top 8.

Good fit Use it to locate related documentation, regulations, process descriptions, or context before changing project configuration; use ordinary grep for code and configuration files.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

zvec scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

zvec — semantic search skill

zvec-tool is a CLI for semantic search over the project knowledge base. It turns documents into a vector index and retrieves relevant fragments by meaning. Use it to find docs, regulations, and business-process notes before doing broad greps.

  • Model: intfloat/multilingual-e5-small (384-dim, multilingual)
  • Indexed scope: the folder you pass to index (only *.md by default; configure via ZVEC_EXTENSIONS)
  • No global DB lock: withCollection opens/closes the DB per call, so search never blocks index

When to use

Call zvec search when you need to:

  • find how a business process is described/documented
  • locate documentation for a specific entity (справочник/документ/регистр)
  • find related regulations or concepts
  • get context before changing project configuration

Do not use zvec to search source code or config files — it only indexes the document folder you configured. For code, run a normal grep instead.

Search command

Run from the project root (the parent of zvec-tool/):

node zvec-tool/zvec.mjs search "<query in RU or EN>" --top 8
Flag Description
--top N Number of results (default: 8)
--json Machine-readable JSON output

Examples

node zvec-tool/zvec.mjs search "учёт товаров на складе" --top 5
node zvec-tool/zvec.mjs search "регистр накопления остатки" --top 8
node zvec-tool/zvec.mjs search "порядок закрытия месяца" --top 6
node zvec-tool/zvec.mjs search "документ поступление" --json

Each result contains: the file path, a score (cosine similarity, > 0.7 is strong), and a 220-char preview. Results are sorted by descending score.

Rebuild the index

# Path is required — point it at your documents folder
node zvec-tool/zvec.mjs index ./docs
# or: node zvec-tool/zvec.mjs index --root ./docs
# or set ZVEC_INDEX_ROOT=./docs

Status & diagnostics

node zvec-tool/zvec.mjs status     # index status: docCount, active version
node zvec-tool/zvec.mjs doctor     # detailed diagnostics (probes DB, shows lock holder)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
