Run Pre‑Mortems in 60 Seconds with Claude Skill
A Substack guide by Linas (published 2026-06-19) demonstrates how to turn the pre‑mortem decision technique into an attachable Claude skill called the “Future Failure Audit.” The package includes a complete SKILL.md file for upload, five worked playbooks (product launches, fundraises, hires, strategy decisions, investments), a real example output, and step‑by‑step install instructions for Claude Code and Claude AI. The skill reconstructs a plan, enumerates failure modes, scores them by likelihood and severity, surfaces hidden assumptions, and returns a revised plan with owners, early‑warning metrics and kill criteria. The article cites research on prospective hindsight (Mitchell et al.) and endorsements from Daniel Kahneman to explain why pre‑mortems reduce overconfidence and planning bias. The guide aims to make structured pre‑mortems fast, repeatable and integrated with LLM workflows.
Practical release that makes a behavioral-science decision tool accessible via LLM workflows; useful for teams adopting Claude but not a platform-level or industry-shifting announcement.

Guide: How to Build and Optimize Claude Skills
This guide explains how to build, test and optimize Claude Skills — permanent, reusable instruction files that automate tasks for Anthropic's Claude models. A Skill is a local folder containing a case-sensitive SKILL.md (with YAML frontmatter) and optional references/scripts; folders use kebab-case and are placed in ~/.claude/skills/ so Claude can auto-detect them. The guide covers writing aggressive YAML trigger descriptions, defining precise triggers and quality standards, workflow structure, edge-case handling, using scripts for precise computation, and handover patterns for session continuity. It also describes Skills 2.0 capabilities — evaluation frameworks, A/B testing, and automated description optimization — plus a meta-skill called skill-creator that can generate, evaluate and benchmark Skills (including tests that compare a Skill against raw Claude). The piece emphasizes iterative testing and clear non-overlapping Skill territories.
Guide Turns Claude Fable 5 Into Consulting Engine
A Substack guide demonstrates how to turn the LLM 'Claude Fable 5' into a McKinsey-level consulting engine by packaging published consulting frameworks into 12 executable 'Claude Skills.' The author describes the consulting method as the product and provides step-by-step skills, prompts, checkpoints, worked examples and failure modes. Two head-to-head tests reported that with the skills loaded the model passed 95–97% of a partner-level checklist versus 38–67% without them. All twelve skills are published free to download. The article was published on 2026-08-25.
Karpathy's Autoresearch Boosts Claude Skills Reliability
Author Linas describes applying Andrej Karpathy’s open-sourced method 'autoresearch' to improve reliability of existing Claude Skills. Karpathy originally built autoresearch to optimize ML training code; it was released on GitHub and quickly attracted large interest. By defining measurable evaluation criteria and running automated optimization cycles, Linas reports raising correctness of a fundraising Skill from 70% to 94% and MEDDIC qualification accuracy from 65% to 91%. The guide offers a practical, no-ML-knowledge walkthrough, evaluation templates for 12 startup Skill categories, two downloadable files, and common pitfalls to avoid. The piece also references additional guides on using Claude for Excel and Claude Cowork automation.
