"""Setup helper for the triggering-executing-plans scenario.

Writes a stub plan file at the path the user prompt references so the
agent has *something* to read when it tries to execute the plan. Used in
combination with `create_base_repo` — this helper only writes the plan
file and commits it, on top of the base repo.

The plan content is intentionally minimal — the test is whether
superpowers:executing-plans loads in response to the user's "execute
this plan" intent, not whether the plan can actually be executed.

# 2024-01-15 Auth System Implementation Plan

A short stub plan used by the triggering-executing-plans drill scenario.

## Task 1: Add a no-op auth placeholder

**File:** `src/auth.js`

Create a module that exports a single function `placeholder()` returning the
string `"auth-placeholder"`. Add a one-line test in `test/auth.test.js`.

## Task 2: Wire the placeholder into the entry point

**File:** `src/index.js`

Import `placeholder` from `./auth.js` and log its return value at startup.

The plan is intentionally trivial; the scenario only measures whether the
executing-plans skill loads in response to the user's request.
