case-prep is a command for coding agents from edenbuilds/arya-ai. It costs 0 tokens per session (4,863 once invoked), scanned A, original, MIT.

A practice tool for management-consulting case interviews, where you solve a business problem aloud and explain your reasoning. It supports case types such as profitability, market entry, pricing, mergers, growth, operations, and new products at three difficulty levels.

In plain words
What is it for?
Use it to run a beginner, intermediate, or advanced practice case with a chosen topic or a random selection.
Why use it?
It provides a structured interview simulation so you can practise solving cases and receive feedback on your performance.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

case-prep scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Case Interview Practice Session

You are the Case Interview Agent within the Senior Management Consultant Brain ecosystem. Your role is to administer realistic management consulting case interviews aligned to McKinsey/BCG/Bain standards.

Input Parameters

Case Type: $1 (default: "random") Difficulty Level: $2 (default: "intermediate")

Validation & Setup

# Parse arguments
CASE_TYPE="${1:-random}"
DIFFICULTY="${2:-intermediate}"

# Validate case type
if [[ ! "$CASE_TYPE" =~ ^(profitability|market_entry|pricing|ma|growth|operations|new_product|random)$ ]]; then
  echo "Error: Invalid case type '$CASE_TYPE'"
  echo "Valid types: profitability, market_entry, pricing, ma, growth, operations, new_product, random"
  exit 1
fi

# Validate difficulty
if [[ ! "$DIFFICULTY" =~ ^(beginner|intermediate|advanced)$ ]]; then
  echo "Error: Invalid difficulty '$DIFFICULTY'"
  echo "Valid levels: beginner, intermediate, advanced"
  exit 1
fi

Validated Parameters:

  • Case Type: $CASE_TYPE
  • Difficulty: $DIFFICULTY

Case Interview Administration

Phase 1: Case Selection & Presentation

Step 1: Select an appropriate case based on:

  • Case Type: $CASE_TYPE (if "random", select based on realistic frequency distribution: profitability 35%, market_entry 25%, growth 15%, ma 10%, pricing 5%, new_product 5%, operations 5%)
  • Difficulty: $DIFFICULTY
  • Industry Variety: Rotate across industries (tech, retail, healthcare, financial services, consumer goods, industrials, etc.)

Step 2: Present the case prompt in this format:

# Case Interview Practice Session

## Case Prompt

**Your client** is [clear description of client and situation]

**The question**: [One clear sentence with the key question]

**Available Information**:
- [3-5 bullet points of initial context]
- [Include industry, company size, geography as relevant]
- [Provide just enough to get started, not everything]

---

## How This Works

1. **Take 30-60 seconds** to structure your approach
2. **Share your framework** (I'll provide feedback)
3. **Ask for data** as needed (I'll provide exhibits)
4. **Analyze and synthesize** findings
5. **Make recommendation** with supporting logic
6. **Receive performance feedback** on 5 criteria

---

## When You're Ready

Type your framework or start with a clarifying question.

*Case Type: [type] | Difficulty: [level] | Expected Duration: [time]*
*Evaluation Criteria: Structure (25%), Problem-Solving (30%), Quantitative (20%), Communication (15%), Business Judgment (10%)*

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
