doors

doors is a skill for Claude Code from askarzh/epistemator. It costs 86 tokens per session (2,364 once invoked), scanned A, original, MIT.

A decision-triage method that separates reversible choices from choices that are difficult to undo. These are often called two-way and one-way doors.

In plain words
What is it for?
Use it to classify a decision, decide how much thinking it needs, and determine whether to act quickly or investigate more before committing.
Why use it?
It helps prevent spending extensive analysis on choices that can be reversed, while identifying decisions that need more information and care. It also looks for ways to make difficult choices easier to reverse.

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

doors 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 7d 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.

One-Way / Two-Way Door Decision Triage

Overview

Apply the One-Way / Two-Way Door decision framework (Type 1 / Type 2 decisions), articulated by Jeff Bezos in his 2015 and 2016 Amazon shareholder letters. This is a meta-analytical triage tool designed for velocity. Its primary purpose is to prevent decision paralysis by determining how much thinking is actually required before acting.

This is not a deep analytical framework like the other four in this toolkit. It is a pre-analytical classifier: it answers "how should I decide?" before you decide "what should I decide?" Highly analytical thinkers often make the mistake of treating all decisions as One-Way doors, deploying heavy cognitive machinery on reversible problems. This framework categorizes the decision, sets the required information threshold, and most importantly, attempts to structurally transform One-Way doors into Two-Way doors to maintain momentum.

The framework is a practitioner tool from business leadership, not academic theory. However, its core insight — that irreversibility under uncertainty creates option value — is rigorously grounded in real options theory (Dixit & Pindyck, Investment under Uncertainty, 1994). The vocabulary is Bezos's; the economics are sound.

Core Methodology

  1. Classify the Door — Determine whether the decision is reversible (Two-Way Door / Type 2) or irreversible (One-Way Door / Type 1). Reversibility is a spectrum, not a binary. Evaluate along three dimensions:

    • Reversal cost: How expensive is it to undo? ($100 vs. $1M are both "reversible" but very different decisions.)
    • Reversal speed: How long does it take to walk back? A feature flag takes seconds; a public announcement takes months of reputation repair.
    • Blast radius: How many people, systems, or commitments are affected? A team experiment vs. a company-wide reorganization.

    If the decision is clearly a Two-Way door, apply the 70% rule and act. If it is clearly a One-Way door, proceed to step 2. If ambiguous, treat it as a One-Way door and proceed to step 3 (transformation).

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.

doors is a skill published in the GitHub repository askarzh/epistemator (3 stars, last pushed 6mo ago), licensed MIT. It adds 86 tokens to every session and 2,364 once invoked, about $0.0004 per session on Opus 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 2026-08-31.
