decision-making

decision-making is a skill for Claude Code, Codex from byronxlg/skillfold. It costs 14 tokens per session (335 once invoked), scanned A, original, MIT.

A structured way to compare choices and explain a recommendation. It records the criteria, alternatives, trade-offs, and reasons behind a decision.

In plain words
What is it for?
Use it to assess technical or product options, compare cost, risk, time, complexity, and maintainability, and document rejected alternatives.
Why use it?
It prevents decisions from resting on the first idea or on unstated assumptions. Others can see what was considered and why an option was chosen.

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-making 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 8d 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.

What it actually says

Decision Making

You evaluate options, weigh trade-offs, and produce clear recommendations with justification. Your decisions are structured and traceable - anyone reading your output can understand what was considered and why.

Principles

  • Make the decision criteria explicit before evaluating options
  • Consider at least two alternatives for any significant decision
  • Separate reversible decisions (move fast) from irreversible ones (move carefully)
  • Acknowledge trade-offs honestly - every option has downsides
  • Document what was rejected and why, not just what was chosen

Approach

When making or recommending a decision:

  1. State the decision to be made and why it matters
  2. Define the criteria that matter (cost, complexity, risk, time, maintainability)
  3. Identify the realistic options - include "do nothing" when relevant
  4. Evaluate each option against the criteria with specific evidence
  5. Note the trade-offs for each option - what you gain and what you give up
  6. Make a recommendation with a clear rationale
  7. State the conditions under which you would revisit this decision

Common Pitfalls

  • Anchoring on the first option considered - deliberately explore alternatives
  • Optimizing for one criterion while ignoring others
  • Confusing familiarity with superiority - evaluate options on their merits
  • Analysis paralysis - set a time box proportional to the decision's reversibility

Output

Present a decision record: the context, options considered with pros and cons, the recommendation, and the rationale. Keep it concise enough to review quickly but detailed enough to be useful months later.

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-making is a skill published in the GitHub repository byronxlg/skillfold (12 stars, last pushed today), licensed MIT. It adds 14 tokens to every session and 335 once invoked, about $0.0001 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 2026-08-30.
