decide

decide is a skill for Claude Code from martineserios/thebrana. It costs 14 tokens per session (776 once invoked), scanned A, original, MIT.

A decision-making helper that turns a question into a recommendation using criteria, scenarios, and decision patterns. It asks for more detail when a choice has several options or important trade-offs.

In plain words
What is it for?
Use it for go/no-go decisions, task prioritisation, product or market direction, architecture choices, and other decisions involving cost, speed, quality, or risk.
Why use it?
It helps reduce uncertainty when you need to choose between options or decide what to do next. Complex choices are made more explicit before giving an answer.

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

decide 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 5d 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.

Decide — Fast Decision

One sentence in, one recommendation out.


Step 1 — Get the question

Use the skill arg if provided. If the conversation makes the question obvious, use that (Recommended). Otherwise ask:

AskUserQuestion: "What's the decision? One sentence."

ToolSearch("select:mcp__ruflo__memory_search_unified")

Step 2 — Detect complexity

Before answering, classify the question:

Simple (fast lane → skip to Step 4):

  • One option to evaluate (go/no-go, yes/no)
  • Task selection ("what to work on next?")
  • Urgency ("should I do X now or later?")

Complex (ask first):

  • 2+ named alternatives (A vs B vs C)
  • Strategic direction (which product area, which market, which architecture)
  • Multi-criteria with real trade-offs (cost vs speed vs quality)
  • High stakes, hard to reverse

For complex questions, surface the right framework before answering:

AskUserQuestion:
  question: "This has multiple alternatives/dimensions. How deep do you want to go?"
  header: "Depth"
  options:
    - label: "Quick take — best guess now"
      description: "I give a recommendation with brief reasoning. Fast, opinionated."
    - label: "Decision matrix — weighted scoring"
      description: "We score each option against criteria with weights. Explicit, defensible. Best for vendor/tool/strategy selection."
    - label: "SWOT first — strategic framing"
      description: "Analyze strengths/weaknesses/opportunities/threats before deciding. Best for product or business direction."
    - label: "Six hats — full perspective sweep"
      description: "Run White/Yellow/Black/Green/Red/Blue lenses. Best for decisions that need both optimism and caution."

If user picks quick take → proceed to Step 4. If user picks decision matrix → invoke decision-matrix skill via Skill tool. If user picks SWOT → invoke swot-analysis skill via Skill tool. If user picks six hats → invoke six-thinking-hats skill via Skill tool.

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.
