decide

A guided process for making an important decision and recording the reasoning in a project repository. It covers clarifying the problem, comparing choices and examining possible failures.

In plain words
What is it for?
Use it for product, architecture or project decisions where trade-offs matter and the reasoning should be saved.
Why use it?
It helps turn a difficult choice into a documented decision that the team can revisit later.

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 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.

How it starts

The opening of the file, as written. The whole thing — 145 lines — stays where its author put it; the contents beside it link to each section on GitHub.

If there is no protocol directory yet, first scaffold one with python3 "${CLAUDE_PLUGIN_ROOT}/scripts/protocol_init.py" . — decisions are recorded in .clarity-protocol/decisions/. If the user named a decision topic when invoking this skill, work through that decision; follow the guide below from the beginning. A decision is not recorded until the --record-decision script step near the end of this guide has run — writing the decision document and updating the index do not record state.

Decision Guidance

Help the user think through an important decision — one where the choice matters, the tradeoffs are real, and the reasoning should be captured.

Overview

Decisions come up throughout a project — during problem clarification, solution brainstorming, architecture design, failure analysis, or just in conversation. This process isn't a phase in a pipeline; it's a tool you reach for when someone hits a fork that deserves careful thought.

You're already good at helping people think through choices. These instructions remind you what makes a decision well-made and well-documented, not how to analyze tradeoffs (you know how to do that).

When to Use This Process

Use this when:

  • A choice has come up that leads to materially different outcomes
  • The user asks "should we do X or Y?" and the answer isn't obvious
  • You notice a decision being made implicitly that should be made explicitly
  • A previous decision needs revisiting because circumstances changed

Don't use this for choices that are straightforward or easily reversible. Not every fork needs a formal process — most don't.

Inputs

Ground your thinking in whatever is relevant from:

  • .clarity-protocol/goal/problem.md — What the project is trying to achieve
  • .clarity-protocol/goal/stakeholders.md — Whose needs matter
  • .clarity-protocol/goal/requirements.md — What constraints apply
  • .clarity-protocol/solution/solution.md — The current approach
  • .clarity-protocol/solution/architecture.md — Technical context

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.

decide is a skill published in the GitHub repository danielrmay/claudity (5 stars, last pushed 2mo ago), licensed MIT. It adds 11 tokens to every session and 1,892 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 2026-08-31.
