Use the hyalo CLI instead of read/edit/grep/write when working with markdown (.md) files that have YAML frontmatter. This skill MUST be consulted whenever pi is working with markdown documentation directories, knowledgebases, wikis, notes, Obsidian-compatible collections, Zettelkasten systems, iteration plans, or any collection of .md files with frontmatter. Trigger this skill when: searching or filtering markdown files by content, tags, or properties; reading or modifying YAML frontmatter…
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
# Hyalo CLI — Prime Tool for Markdown Knowledgebases in pi Ranked queries return `score` and up to three body `matches` with `line`, `section`, and `text`; text output displays that context directly. Snippets rank by distinct query tokens then line number and share stemming, OR and CJK rules with scoring. Quoted phrases must fit on one line. `--section` scopes snippets; frontmatter is excluded, so title-only hits can have an empty array. Indexed queries read snippet text only for final results after `--limit`. Hyalo is a fast CLI for querying and mutating YAML frontmatter, tags, tasks, and structure in directories of markdown files. If the hyalo pi extension is installed (`.pi/extensions/hyalo.ts`), prefer its **typed tools** for the common operations — they take structured parameters, so there is no flag spelling or quoting to get wrong: | Operation | Typed tool | Example parameters | |-----------|------------|--------------------| | Search/filter | **hyalo_find** | `property: ["status=planned", "type=iteration"]`, `query: "rust"`, `tag: "feature"`, `taskStatus: "todo"`, `countOnly: true`, `limit: 10` | …

How to install
mdr add ractive/hyalo/hyalo@sha256:4806a9e40846e3f0The line at the top of this page pins the label git:20261005.191a694, 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.
