decision-matrix

decision-matrix is a skill for Claude Code, Codex from fzfclee/consulting-skills. It costs 51 tokens per session (723 once invoked), scanned A, original, Apache-2.0.

A structured way to choose between several options by defining criteria, assigning their importance, and comparing evidence. It removes options that fail required conditions before scoring the rest.

In plain words
What is it for?
It helps compare viable options, record assumptions when information is missing, weigh trade-offs, and produce an action plan.
Why use it?
It makes decisions easier to explain and defend instead of relying only on intuition or changing criteria after seeing the results.

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-matrix 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 9d 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.

Decision Matrix

Use this skill to run Decision Matrix as a practical consulting method, not as a generic framework explanation.

Method Notes

  • Define criteria before scoring options.
  • Weights should reflect the real decision, not post-hoc preference.

Required Inputs

Collect or infer these inputs before execution:

  • options
  • decision criteria
  • weights
  • evidence for scoring

If an input is missing, do not block automatically. Mark it as missing, state the assumption used, and add a validation action.

When Not To Use

Do not use when there is only one viable option, the decision criteria are not agreed, or mandatory requirements remain unresolved. Apply hard gates before weighted scoring.

Adjacent Methods

  • weighted-scorecard: repeatable governance evaluation across comparable entities.
  • rice-scoring: product or initiative backlog prioritization.
  • wsjf-prioritization: sequencing by Cost of Delay and Job Size.

Step-by-Step Execution

Step Required input How to execute Output
Define decision Decision statement, options, must-have constraints. Remove non-viable options before scoring. Viable option set.
Choose criteria Objectives, stakeholder priorities, risk constraints. Select criteria that actually decide success. Criteria list.
Weight criteria Criteria and decision priorities. Assign weights totaling 100 percent or another explicit scale. Weighted criteria.
Score options Options, criteria, evidence. Score each option against each criterion and record rationale. Completed decision matrix.
Recommend and test Scores and uncertain assumptions. Pick recommendation, show tradeoffs, and test whether weight changes alter the choice. Decision recommendation.
