Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00059 | $0.02016 |
| Opus 5.5 | $0.00024 | $0.00806 |
| Sonnet 5.5 | $0.00012 | $0.00403 |
| Haiku 4.5 | $0.00006 | $0.00202 |
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 1mo 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.
How it starts
The opening of the file, as written. The whole thing — 142 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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
- Clarify the decision — State the decision in one clear sentence. Define what "success" looks like and the deadline by which you must decide.
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.

decision-maker is a skill published in the GitHub repository NickCrew/Claude-Cortex (61 stars, last pushed 4mo ago), licensed MIT. It adds 59 tokens to every session and 2,016 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
