| Package map for shared utilities: atomic file writes, branded ids, deques, JSON values, harness home paths, launch environment, native commands, output retention, time and zone vocabulary, timeouts, and official package lists. | package-group |
util/ — shared utilities
English | 中文
Summary
The util/ group gives capability packages shared mechanical primitives instead of duplicate implementations. It covers atomic writes, branded ids, deques, lossless JSON values, UUIDs, Harness-home paths, launch environments, outbound proxy policy, native commands, output retention, time-zone, instant, and span vocabulary, and timeout handling. Every root entry here is a library: it registers no product service or event, and the consuming capability retains the business semantics. The exception is official-bundles: instead of a mechanical primitive, it holds the installation's and the plugin manager's official package lists as data their consumers apply.
Table of Contents
Packages
Each package provides one primitive or one data set; open a package page for how to use it.
| Package | Role |
|---|---|
brand/ |
Nominal string types and their stateless constructor |
package-manifest/ |
Shared TypeScript declarations for package manifests |
plugin-detail/ |
Selects plugin detail documents and reads them from local packages and npm file CDNs |
plugin-market-index/ |
Validates plugin market index format 1 and builds pinned install arguments |
official-bundles/ |
Lists the official bundle and plugin packages the installation ships, offers, installs on demand, retires, and the plugin manager protects or presents |
crypto/ |
Mints RFC 9562 v4 UUIDs from the cross-runtime crypto.getRandomValues primitive |
deque/ |
Provides amortized constant-time queue operations with bounded vacant storage |
chunked-list/ |
Retains immutable list versions with bounded append copying and checkpoint validation |
values/ |
Validates, snapshots, compares, and freezes lossless JSON-compatible values |
home-paths/ |
Resolves the single Harness home and joins shared user-data paths |
http-proxy/ |
Resolves one outbound proxy policy and installs it for fetch, SDK agents, and spawned children |
launch-environment/ |
Frozen launch environment that remembers which layer supplied each value |
atomic-write/ |
Atomic file replacement and cross-process writer locking |
lazy-require/ |
Loads CommonJS-compatible Host dependencies on first use with caller-relative resolution |
native-command/ |
Runs host-native commands directly, never through a shell string |
workspace-path/ |
Provides browser-safe Workspace path and display helpers |
code-language/ |
Maps a filename suffix to the syntax-highlighting language that the Code preview, diff review, and the read card render |
output-retention/ |
Bounds model-facing output and reports exact omission metadata |
time/ |
Parses strict instants, local calendars, and caller-reported IANA zones, and holds a millisecond span |
timeout/ |
Deadline arithmetic, signal fusion, and timeout-versus-cancel classification |
