decision-maker

decision-maker is a skill for Claude Code, Codex from NickCrew/Claude-Cortex. It costs 59 tokens per session (2,016 once invoked), scanned A, original, MIT.

A structured decision-making guide for comparing important choices. It includes methods such as pros-and-cons lists, weighted scoring, prioritisation, and pre-mortem analysis, which asks what could go wrong before deciding.

In plain words
What is it for?
Use it for career choices, product priorities, vendor selection, hiring, or other decisions involving multiple criteria and stakeholders.
Why use it?
It makes trade-offs visible and creates a reasoned record of how a decision was made. This reduces the effect of uncertainty and personal bias.

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

decision-maker 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 yesterday.

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.

Decision Maker

Overview

This skill applies proven decision-making frameworks—pros/cons analysis, weighted scoring matrices, RICE prioritization, the Eisenhower urgency-importance matrix, and pre-mortem analysis—to help you cut through ambiguity and make defensible, well-reasoned choices. By externalizing the decision into a structured format you reduce cognitive bias, surface hidden trade-offs, and create a record of your reasoning that can be revisited or shared with stakeholders.

When to Use

  • You have two or more meaningful options and are unsure which to choose
  • The decision has significant, lasting consequences (career, finances, product roadmap, hiring)
  • Multiple stakeholders need to align around a shared rationale
  • You feel emotionally stuck and want an objective framework to cut through the noise
  • You need to prioritize a backlog of features, tasks, or projects
  • You want to stress-test a decision you've already leaned toward

When NOT to Use

  • The decision is low-stakes and reversible (where any choice is fine)
  • You need licensed advice (legal, medical, financial) — frameworks support, not replace, professionals
  • The situation requires immediate crisis action with no time for structured analysis
  • Data needed to score criteria is completely unavailable or unknowable
  • You simply want validation for a decision already firmly made

Quick Reference

Framework Best For Output
Pros / Cons Simple binary choices, fast gut-check Two-column list
Weighted Scoring Matrix Multi-option, multi-criteria trade-offs Ranked score table
RICE Feature or project prioritization Priority-ranked backlog
Eisenhower Matrix Task triage and time management 4-quadrant urgency/importance grid
Pre-Mortem Risk identification before committing List of failure modes and mitigations

Instructions

  1. Clarify the decision — State the decision in one clear sentence. Define what "success" looks like and the deadline by which you must decide.

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.
