update is a command for Claude Code from edochi/mdvs. It costs 0 tokens per session (1,583 once invoked), scanned A, original, MIT.

A command that rescans a Markdown directory and adds newly discovered frontmatter fields to mdvs.toml, the project's configuration file. It can preview changes or explicitly reinfer field definitions.

In plain words
What is it for?
It is for discovering new metadata fields, reviewing possible schema changes, and selectively recalculating field definitions.
Why use it?
It keeps the schema aligned with the notes as the knowledge base grows while protecting existing field rules by default.

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

update 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 10d 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.

How it starts

The opening of the file, as written. The whole thing — 185 lines — stays where its author put it; the contents beside it link to each section on GitHub.

update

Re-scan files, infer new fields, and update the schema.

Usage

mdvs update [path] [--dry-run]
mdvs update [path] reinfer [fields..] [flags]

Flags

Flag Default Description
path . Directory containing mdvs.toml
--dry-run Preview changes without writing anything

Global flags (-o, -v, --logs) are described in Configuration.

What it does

update re-scans the directory using the existing [scan] config, infers types and path patterns from the current files, and merges the results into mdvs.toml. Unlike init, it preserves all existing configuration — only the [fields] section changes.

Default mode

By default, update only discovers new fields — fields that appear in frontmatter but aren't yet in mdvs.toml (either as [[fields.field]] entries or in the ignore list). Existing fields are protected: their types, allowed/required patterns, nullable flags, and constraints don't change.

Fields that disappear (no longer in any file) are kept in mdvs.toml by default. This is conservative — removing a field from the schema is an explicit action.

reinfer subcommand

Re-infer field definitions from scratch. This is a subcommand of update with its own flags:

Flag Description
fields.. Fields to reinfer (all if none specified)
--with <kinds> Comma-separated constraint kinds to apply (categorical, range, none). Requires named fields.
--max-categories <N> Override max distinct values for categorical inference
--min-repetition <N> Override min average repetition for categorical inference
--dry-run Preview changes without writing anything

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.

update is a command published in the GitHub repository edochi/mdvs (27 stars, last pushed 11d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,583 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-10-05.
