description	This skill should be used when the user asks to "build a new command", "create a command", "implement a command", "add a new CLI command", or needs to build a new command for CLI for Microsoft 365 from a GitHub issue spec. It covers the full workflow: command logic, unit tests, documentation, sidebar registration, and PR checklist verification.

Building a New Command for CLI for Microsoft 365

Build a complete, production-ready CLI command from a GitHub issue spec. The workflow produces four artifacts: command implementation, unit tests, documentation page, and sidebar registration — then verifies everything against the PR checklist.

Prerequisites

A GitHub issue containing the command spec (name, description, options, examples, API details). If no issue is provided, STOP — ask the user for the issue URL or spec before proceeding.

Workflow

Execute each phase in order. Do not skip phases.

Phase 1: Parse the Spec

1. Read the GitHub issue thoroughly.
2. Extract: command name, description, service/workload, options (required/optional, types, aliases, allowed values, option sets), API endpoints used, example usage, and expected response shape.
3. STOP — Verify API details are complete. The spec must include the full API endpoint(s), HTTP method(s), request payloads, and response shapes. If any of these are missing, ask the user to provide them or point to API documentation. NEVER fabricate or infer API request/response shapes — even if similar commands exist in the codebase.
4. Identify the base class. Look at existing commands in src/m365/<service>/commands/ to determine which base class to extend (SpoCommand, GraphCommand, GraphApplicationCommand, AzmgmtCommand, etc.).
5. Check that every word in the command name exists in the dictionary in eslint.config.mjs. If a word is missing, add it to the dictionary array (keep alphabetical order).

Phase 2: Implement the Command

Create src/m365/<service>/commands/<noun>/<noun>-<verb>.ts.

Structure

import { globalOptionsZod } from '../../../../Command.js';
import { z } from 'zod';
import { Logger } from '../../../../cli/Logger.js';
import commands from '../../commands.js';
import <BaseCommand> from '../../../base/<BaseCommand>.js';
import request, { CliRequestOptions } from '../../../../request.js';
// additional imports as needed

// Enums for options with predefined values
// enum Foo { Bar = 'bar', Baz = 'baz' }

export const options = z.strictObject({
  ...globalOptionsZod.shape,
  // command-specific options
});
declare type Options = z.infer<typeof options>;

interface CommandArgs {
  options: Options;
}

class <Service><Noun><Verb>Command extends <BaseCommand> {
  public get name(): string {
    return commands.<NOUN>_<VERB>;
  }

  public get description(): string {
    return '<description from spec>';
  }

  public get schema(): z.ZodType {
    return options;
  }

  // getRefinedSchema — only if option sets or cross-field validation needed

  public async commandAction(logger: Logger, args: CommandArgs): Promise<void> {
    try {
      if (this.verbose) {
        await logger.logToStderr(`<Verbose message>...`);
      }

      const requestOptions: CliRequestOptions = {
        url: `<endpoint>`,
        headers: { accept: 'application/json;odata.metadata=none' },
        responseType: 'json'
      };

      const result = await request.get<any>(requestOptions);
      await logger.log(result);
    }
    catch (err: any) {
      this.handleRejectedODataJsonPromise(err);
    }
  }
}

export default new <Service><Noun><Verb>Command();

Key rules

• Class name: <Service><Noun><Verb>Command in PascalCase.
• Options: use z.strictObject spreading globalOptionsZod.shape.
• Aliases: .alias('x') on the Zod property.
• Enums: zod.coercedEnum(MyEnum) for case-insensitive matching. Import { zod } from ../../../../utils/zod.js.
• Validation: Zod refinements on properties (.refine()), not custom validate methods.
• URL validation for SharePoint: .refine(url => validation.isValidSharePointUrl(url) === true, { error: '...' }).
• Option sets: implement getRefinedSchema(schema) returning schema.refine(...).
• Async/await only — no .then().
• Verbose/debug logging → logger.logToStderr.
• Error handling → this.handleRejectedODataJsonPromise(err).
• SPO file/folder endpoints: use GetFileByServerRelativePath / GetFolderByServerRelativePath.
• Remove commands: include a force option and confirmation prompt using cli.handleMultipleResultsFound or cli.promptForConfirmation.
• No any types (except the catch clause). Use specific interfaces/types.
• No commented-out code.

Register the command name

Add the command constant to src/m365/<service>/commands.ts, keeping groups alphabetically sorted:

export default {
  // ...existing commands...
  <NOUN>_<VERB>: `${prefix} <noun> <verb>`,
  // ...
};

Phase 3: Write Unit Tests

Create src/m365/<service>/commands/<noun>/<noun>-<verb>.spec.ts.

Skeleton

import assert from 'assert';
import sinon from 'sinon';
import auth from '../../../../Auth.js';
import { CommandError } from '../../../../Command.js';
import { cli } from '../../../../cli/cli.js';
import { CommandInfo } from '../../../../cli/CommandInfo.js';
import { Logger } from '../../../../cli/Logger.js';
import { telemetry } from '../../../../telemetry.js';
import { pid } from '../../../../utils/pid.js';
import { session } from '../../../../utils/session.js';
import { sinonUtil } from '../../../../utils/sinonUtil.js';
import request from '../../../../request.js';
import commands from '../../commands.js';
import command, { options as commandOptionsSchema } from './<noun>-<verb>.js';

describe(commands.<NOUN>_<VERB>, () => {
  let log: any[];
  let logger: Logger;
  let loggerLogSpy: sinon.SinonSpy;
  let commandInfo: CommandInfo;

  before(() => {
    sinon.stub(auth, 'restoreAuth').resolves();
    sinon.stub(telemetry, 'trackEvent').resolves();
    sinon.stub(pid, 'getProcessName').returns('');
    sinon.stub(session, 'getId').returns('');
    auth.connection.active = true;
    commandInfo = cli.getCommandInfo(command);
  });

  beforeEach(() => {
    log = [];
    logger = {
      log: async (msg: string) => { log.push(msg); },
      logRaw: async (msg: string) => { log.push(msg); },
      logToStderr: async (msg: string) => { log.push(msg); }
    };
    loggerLogSpy = sinon.spy(logger, 'log');
  });

  afterEach(() => {
    sinonUtil.restore([
      request.get,
      request.post,
      request.put,
      request.patch,
      request.delete
      // restore only the HTTP methods actually stubbed
    ]);
  });

  after(() => {
    sinon.restore();
    auth.connection.active = false;
  });

  it('has the correct name', () => {
    assert.strictEqual(command.name, commands.<NOUN>_<VERB>);
  });

  it('has a description', () => {
    assert.notStrictEqual(command.description, null);
  });

  // Validation tests — one pass and one fail per validation rule
  // Option set tests — valid combos and invalid combos
  // commandAction tests — one per branch/code path
  // API error test
});

Required test categories

1. Name and description — always.
2. Validation — each Zod refinement tested for pass and fail using commandOptionsSchema.safeParse(...).
3. Option sets — valid single option, invalid multiple options, missing required option.
4. Command action — one test per logical branch. Stub request.get/post/etc. with callsFake matching URL patterns.
5. Error handling — stub request to reject, assert CommandError.
6. Coverage — every if, switch, catch branch hit. Target 100% code and branch coverage.

Run tests

npm test

Check coverage in coverage/lcov-report/index.html. If coverage is below 100% on the new command file, add tests for missed branches.

Phase 4: Write Documentation

Create docs/docs/cmd/<service>/<noun>/<noun>-<verb>.mdx.

Template

import Global from '../../_global.mdx';
import Tabs from '@theme/Tabs';
import TabItem from '@theme/TabItem';

# <service> <noun> <verb>

<Description from spec>

## Usage

```sh
m365 <service> <noun> <verb> [options]
```

## Options

```md definition-list
`-<alias>, --<option> <<option>>`
: <Description>. <Constraints>.

`--<optionalOption> [<optionalOption>]`
: <Description>.
```

<Global />

## Permissions

<!-- Generate with: node ./scripts/generate-docs-permissions.mjs -->

<Tabs>
  <TabItem value="Delegated">

  | Resource   | Permissions |
  |------------|-------------|
  | ...        | ...         |

  </TabItem>
  <TabItem value="Application">

  | Resource   | Permissions |
  |------------|-------------|
  | ...        | ...         |

  </TabItem>
</Tabs>

## Examples

<At least 2 examples using long option names>

```sh
m365 <service> <noun> <verb> --<option> <value>
```

## Response

<Tabs>
  <TabItem value="JSON">

  ```json
  { ... }
  ```

  </TabItem>
  <TabItem value="Text">

  ```text
  ...
  ```

  </TabItem>
  <TabItem value="CSV">

  ```csv
  ...
  ```

  </TabItem>
  <TabItem value="Markdown">

  ```md
  ...
  ```

  </TabItem>
</Tabs>

Rules

• Required options: angle brackets <option>. Optional: square brackets [option].
• Examples use long option names, start with m365.
• Normalize data: tenant → contoso, no real PII.
• List commands: JSON wrapped in [ ] with one item.
• No output commands: write The command won't return a response on success.
• Add Remarks section between Options and Examples if needed (preview API, 0-based index, etc.).

Register in sidebar

Edit docs/src/config/sidebars.ts. Find the correct service section, locate or create the command group, add the doc entry alphabetically:

{
  type: 'doc',
  label: '<noun> <verb>',
  id: 'cmd/<service>/<noun>/<noun>-<verb>'
}

Phase 5: Verify

STOP — Read references/pr-checklist.md and verify every item passes before declaring done.

1. Run npm run build — must pass.
2. Run npm test — all tests green.
3. STOP — Check the coverage output for the new command file. All four metrics (Stmts, Branch, Funcs, Lines) must show 100%. If any metric is below 100%, add tests for the uncovered lines/branches and re-run until all are 100%. Do NOT proceed until this passes.
4. Walk through every checklist item in references/pr-checklist.md.
5. Fix any failures before proceeding.

Only after all checks pass is the command complete.
