@elizaos/plugin-cli
CLI framework infrastructure for elizaOS agents: command registration, a TTY-aware progress reporter, and duration/byte formatting helpers.
Purpose / role
This plugin provides the scaffolding for building a Commander-based CLI on top of an Eliza agent runtime. It ships a module-level command registry that other plugins or host apps populate at startup, plus buildProgram / runCli entry points that assemble the final CLI. It is opt-in — load it explicitly via the agent's plugin list. It registers no actions, providers, services, evaluators, or routes; its value is its exported API.
Plugin surface
The cliPlugin export (default) registers:
| Field | Value |
|---|---|
name |
"cli" |
actions |
[] |
providers |
[] |
services |
[] |
routes |
[] |
config |
CLI_NAME, CLI_VERSION (see below) |
init |
Logs count of registered commands; no persistent side effects |
dispose |
Returns immediately |
All real functionality is in the exported API (registry + utils), not in the plugin object's hooks.
Exported API
src/index.ts — entry point
cliPlugin— thePluginobject; default export.buildProgram(options?)— constructs aCommandwith all registered commands attached; returns the Commander root.runCli(argv?, options?)— callsbuildProgram, thenprogram.parseAsync. Passargvto overrideprocess.argv.- Re-exports
Commandfromcommanderfor convenience.
src/registry.ts — command registry
Module-level Map<string, CliCommand> — shared across all imports in the same process.
| Export | Purpose |
|---|---|
registerCliCommand(cmd) |
Add a CliCommand; warns and replaces on duplicate name |
unregisterCliCommand(name) |
Remove by name; returns boolean |
getCliCommand(name) |
Look up by name |
listCliCommands() |
All commands sorted by priority (lower = earlier, default 100) |
registerAllCommands(ctx) |
Called by buildProgram; iterates sorted list, calls each register(ctx) |
clearCliCommands() |
Empties the registry — test helper only |
defineCliCommand(name, description, register, options?) |
Factory for CliCommand; accepts optional aliases and priority |
addSubcommand(parent, name, description) |
Thin wrapper: parent.command(name).description(description) |
src/utils.ts — utilities
| Export | Purpose |
|---|---|
DEFAULT_CLI_NAME |
"elizaos" |
DEFAULT_CLI_VERSION |
"1.0.0" |
resolveCliName(argv?) |
Derives CLI name from process.argv[1] (strips path + extension) |
createDefaultDeps() |
Returns CliDeps (console.log, console.error, process.exit) |
createProgressReporter(deps, options?) |
TTY-aware spinner; falls back to plain log when not a TTY |
withProgress(deps, message, fn) |
Runs an async function with spinner; succeeds/fails reporter automatically |
parseDurationMs(input) |
Parses "1s", "5m", "2h", "7d", bare ms numbers → ParsedDuration |
parseTimeoutMs(input?, defaultMs) |
parseDurationMs with a fallback default |
formatDuration(ms) |
ms → human string ("1.5s", "3.2m", "1.0h") |
formatBytes(bytes) |
Bytes → "1.4 MB" etc. |
formatCliCommand(command, options?) |
Formats elizaos [--profile P] [--env E] <command> |
isInteractive() |
stdin.isTTY && stdout.isTTY |
src/types.ts — shared types
CliContext, CliCommand, CliRegistrationFn, CliPluginConfig, CliLogger, ProgressReporter, ProgressOptions, CliDeps, ParsedDuration, CommonCommandOptions.

Config / env vars
Declared in agentConfig.pluginParameters but not read from process.env by any source file. Pass values directly to buildProgram / runCli as call-site options:
| Variable | Required | Default | Description |
|---|---|---|---|
CLI_NAME |
No | "elizaos" |
CLI binary name shown in help output |
CLI_VERSION |
No | "1.0.0" |
Version string shown by --version |
Pass via buildProgram({ name: "myapp", version: "2.0.0" }) or runCli(argv, { name, version }). The init function does not read the config parameter (_config is intentionally unused).
How to extend
Add a new CLI command
- Call
defineCliCommand+registerCliCommandbeforebuildProgramruns (typically at module load time or in your plugin'sinit):
import { defineCliCommand, registerCliCommand } from "@elizaos/plugin-cli";
registerCliCommand(
defineCliCommand(
"my-cmd",
"Does something useful",
(ctx) => {
ctx.program
.command("my-cmd")
.description("Does something useful")
.option("--flag", "a flag")
.action((opts) => {
const runtime = ctx.getRuntime?.();
// ...
});
},
{ priority: 50 }, // lower = registered earlier
),
);
- The command appears in
elizaos --helpautomatically oncebuildProgramis called.
Use the progress reporter in a command
import { createDefaultDeps, withProgress } from "@elizaos/plugin-cli";
const deps = createDefaultDeps();
await withProgress(deps, "Doing work", async () => {
await someLongOperation();
});
Conventions / gotchas
- The command registry is module-level state (a
Map). In a single Node/Bun process all imports share the same registry; in tests always callclearCliCommands()inbeforeEach/afterEachto avoid cross-test pollution. buildProgramiterateslistCliCommands()at call time. Register all commands before callingbuildProgram.registerCliCommandsilently replaces on duplicate name (with alogger.warn). Use distinct names to avoid accidental overrides.- The plugin object itself has no persistent resources:
disposereturns immediately andinitonly logs. createProgressReporterwrites directly toprocess.stdoutusing ANSI escapes whenisTTY; it degrades to plaindeps.login non-TTY environments (CI, piped output).parseDurationMsreturns{ valid: false, ms: 0 }on bad input — always checkvalidbefore usingms.- Build output goes to
dist/(.gitignored). The package ships onlydist/— nosrc/in the published tarball.
⛔ NON-NEGOTIABLE — evidence, trajectories & real end-to-end tests
The binding, repo-wide standard is AGENTS.md. Read it. Nothing in this package is done until it is proven done — a reviewer must confirm it works without reading the code, from the artifacts you attach. This applies to every feature, fix, refactor, and chore here. "Tests pass" is not proof; "CI is green" is not proof.
- Record AND read model trajectories. Capture the actual inputs and outputs of the model
from a live LLM — not the deterministic proxy, not a mock: the prompt, the
providers/context, the raw model output, every tool/action call, and the result. Then open
the trajectory and review it by hand. A captured-but-unread trajectory is not evidence
(
packages/scenario-runner/bin/eliza-scenarios run <scenario> --report <out>). - Real, full-featured E2E — no larp. Every feature ships detailed end-to-end tests that drive the real path end to end. Not the happy "front door" only: cover error paths, edge/empty/invalid input, concurrency, roles/permissions, and adversarial input. A test that asserts against a mock/stub/fixture standing in for the thing under test does not count. If the real model/device/chain/connector/account is hard to reach, make it reachable — that is the work, not an excuse to mock. If the existing tests here are shallow or mocked, fixing them is part of your change.
- Screenshots + logs at every phase, plus a complete walkthrough video/run-through of
the entire feature or view, start to finish (
bun run test:e2e:record). - Manually review every artifact the change touches — never just the green check: client
logs (console + network), server logs (
[ClassName] …), the model trajectories in and out, before/after full-page screenshots, and the domain artifacts listed below for this package. - No residuals. No shortcuts. The goal is not "done" — it is everything done. Clear every blocker by the hard path: build the real architecture, stand up the real model/device/service, actually test it. Never leave a TODO, a stub, a stepping-stone, or a "follow-up." When unsure, research thoroughly, weigh the options, and ship the best, highest-effort, production-ready version. Keep going until every possibility is exhausted.
Artifacts → attached inline in the PR (MP4 video, JPG screenshots, logs in <details>); attach each evidence type or
explicitly mark it N/A with a reason — never leave it blank. If develop moved and changed
behavior, re-capture evidence; stale proof is worse than none.
Capture & manually review for this package — CLI / tooling:
- The real command/flow invocation transcript (args in, stdout/stderr, exit code) and the artifacts it generated (files, scaffolds, manifests, screenshots/recordings).
- Failure paths: bad args, missing deps, partial state, permission/network errors.
- A recording/log of the actual run end to end — not a unit test of one helper.
- Any model interaction captured as a live trajectory and reviewed.
