The charly CLI

charly is one binary with a large command surface, and almost none of it is in the binary’s own source. Understanding that split makes the CLI reference easier to read.

A small spine, a large catalog

Three top-level words are the core spine, implemented by the binary itself:

Word	What it is
charly box	the build/authoring parent — its subcommands are plugin-served
charly version	the CalVer identity of the running binary
charly reap-orphans	internal cleanup of orphaned resources

Everything else — bundle, check, secrets, candy, alias, agent, clean, status, shell, vm, config and the rest — is a command word served by a plugin candy. Each has a page in the CLI reference naming the plugin that serves it and whether that plugin is compiled into the binary or loaded at runtime.

Some plugin-served words nest under a parent: add-candy, generate, list, new, pkg, validate and friends are children of charly box. The nesting is expressed in the plugin’s Go code rather than its manifest, so the reference pages name the word and its owner without asserting where it sits — run charly box --help for the live tree.

Getting live help

The generated pages here describe what serves a word and why. For the exact flags of a given invocation, ask the binary:

charly bundle add --help
charly box build --help

A wrinkle worth knowing

For a plugin-served word, charly <word> --help is answered by the host and shows a generic stub. The plugin’s own grammar appears one level deeper (charly bundle add --help) or via the bare form (charly bundle help). This is also why this site’s CLI reference is generated from each plugin’s declarations rather than scraped from help output — the help surface is not uniform enough to parse.

Driving it from an agent

The same binary is an MCP server, so every verb is reachable over RPC:

charly mcp serve

An agent authoring a candy uses the same commands you would — charly candy set, charly candy add-rpm, charly box write — with comments and key order preserved across edits.
