.agents/skills/make-decision/SKILL.md

make-decision is a skill for Claude Code, Codex from HoangTheQuyen/think-better. It costs 126 tokens per session (2,443 once invoked), scanned B, original, MIT.

A structured guide for making decisions by comparing options, identifying common thinking biases, and choosing an analysis approach.

In plain words
What is it for?
Use it to compare options, weigh pros and cons, plan strategic or career choices, and facilitate group decisions.
Why use it?
It turns a vague choice into a clear evaluation, helping reduce overlooked trade-offs and misleading assumptions.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is HoangTheQuyen/think-better's own configuration. It tells Claude Code and Codex how to work on think-better itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything think-better configures →

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 B, and why

make-decision scanned grade B with 1 finding 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 10d ago.

The scan reads SKILL.md. This mod also ships 4 executable files (scripts/advisor.py, scripts/core.py, scripts/populate_data.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Goal

Help users make better decisions in minutes instead of hours by applying proven frameworks, detecting cognitive biases, and structuring the evaluation process.

make-decision

Comprehensive decision-making framework for structured evaluation of options. Contains 10 decision frameworks, 8 decision type classifications, 12 cognitive biases with debiasing strategies, 10 analysis techniques, 8 domain-specific criteria templates, and 8 group facilitation techniques. Searchable knowledge base with BM25 ranking that auto-recommends frameworks, criteria, and bias warnings tailored to your specific decision type.

Prerequisites

IMPORTANT: Detect the correct Python command first. Some systems use python3, others use python. Run:

python3 --version 2>/dev/null || python --version

Use whichever command succeeds (python3 or python) for ALL script calls below. If the system only has python (common on Windows), substitute python everywhere you see python3 in this document.

If Python is not installed at all, install it based on user's OS:

macOS:

brew install python3

Ubuntu/Debian:

sudo apt update && sudo apt install python3

Windows:

winget install Python.Python.3.12

Note: On Windows, Python 3 is typically available as python (not python3).


How to Use This Workflow

When user requests decision-making help (decide, choose, compare, evaluate, select, prioritize, trade-off, weigh options), follow this workflow:

Step 1: Understand the Decision

Extract key information from user's decision description:

  • Decision type: Binary choice, multi-option, resource allocation, strategic, operational, under uncertainty, group/stakeholder, time-pressured
  • Options: What alternatives are being considered?
  • Context: Industry, stakes, timeline, stakeholders, reversibility
  • Constraints: Budget, time, resources, dependencies

Step 2: Generate Decision Plan (REQUIRED)

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.
