five-step-method

A five-step decision framework for deciding whether and how to act on requests, from feature work and bug fixes to planning and deployment.

In plain words
What is it for?
Use it to assess requests, feedback, fixes, process changes, vendor choices, meetings, strategies, and configuration problems.
Why use it?
It helps identify unnecessary work and question requirements before adding code, tools, or process.

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

five-step-method 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 2d 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.

Five-Step Work Method

A universal decision framework that teaches you to evaluate whether to act before deciding how to act. Apply this to any decision — code, product, strategy, process, hiring, meetings, or resource allocation.

When to Apply

Trigger Action
New feature / product request Must apply — Question need before designing
External feedback (multiple points) Must apply — Evaluate each point independently
Bug fix that requires > 10 lines Must apply — Question if the fix adds complexity
Process / workflow change proposal Must apply — Can we delete the process instead?
New tool / vendor / hire decision Must apply — Is the role/tool actually needed?
Meeting or review request Must apply — Can this be an async message?
Strategy / roadmap planning Must apply — Delete low-impact items first
Configuration / deployment issue Must apply — Ask if code change is even needed
Single-line typo or obvious fix Skip — Just fix it
User gives explicit instructions Skip — Follow instructions, then review

The Five Steps

Step 1: Question the Requirement

Ask: "Is this actually needed? What happens if we don't do it?"

  • Challenge every request, including your own instincts
  • Check if the problem solves itself (e.g., agent self-corrects after retry)
  • Distinguish "nice to have" from "actually broken"
  • Ask who benefits and how often
  • If only one user hit it once, it's probably not a product problem

Decision matrix:

Frequency Impact Action
Common + High Do it Proceed to Step 2
Common + Low Maybe Proceed to Step 2
Rare + High Record Log for later, don't code now
Rare + Low Skip Don't do it

Step 2: Delete

Remove what shouldn't exist before adding anything.

  • Delete the feature, code, or process that created the problem
  • Delete options when a sensible default works
  • Delete fallbacks when the primary path is reliable
  • Delete auto-detection when one config line suffices
  • Delete backwards-compatibility shims for things nobody uses

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.
