s4h-ethics-impact-scan

s4h-ethics-impact-scan is a skill for Claude Code from human-avatar/skills-for-humanity. It costs 105 tokens per session (1,285 once invoked), scanned A, original, MIT.

A quick ethical check for a proposed feature, product change, or decision before it ships. It asks who benefits, who may be harmed, and how widely those effects are distributed.

In plain words
What is it for?
Use it before releasing a feature, changing a product, or adopting a policy when you need a short review of likely benefits, burdens, and affected groups.
Why use it?
It brings affected people into view before the team commits to a design or release. It can catch harms that are widespread but small for each person, as well as harms concentrated on people with less power.

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

s4h-ethics-impact-scan 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.

How it starts

The opening of the file, as written. The whole thing — 114 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Ethics Impact Scan

A pre-ship ethical scan. Not a deep council — a structured sweep that forces you to see who's in the blast radius before you commit.

It runs two lenses: utilitarian (net effect on aggregate wellbeing) and justice/fairness (whether benefits and burdens are distributed equitably). These two together catch the most common pre-ship blind spots: harm that's small-per-person but large-in-aggregate, and harm that falls disproportionately on people with the least power.


Your Process

Step 1: Clarify the subject State what is being scanned — a feature, change, product decision, or policy. If the subject is vague, ask one clarifying question before proceeding.

Framing check: Confirm the specific ethical situation before continuing. State what you've identified — the actual thing being scanned and the parties most likely affected — in one sentence, then use AskUserQuestion:

  • Question: "I'm reading this as: [your one-sentence framing of the specific feature/decision and who it affects]. Is that right?"
  • Header: "Framing"
  • Options:
    • Yes — proceed — framing is correct
    • Adjust — one element is off; user will correct it before you continue
    • Reframe — different situation than read; incorporate the correction before proceeding

Step 2: Map the stakeholder field Before applying any lens, identify everyone affected:

  • Direct users (who uses this feature and how?)
  • Indirect parties (who is affected by users' use of this feature?)
  • Third parties (suppliers, partners, communities)
  • Non-users (people who don't opt in but are still affected)
  • Future parties (people who will be affected by the precedent this sets)

Don't skip non-users and future parties. They are the most commonly missed.

Step 3: Apply the Utilitarian Lens For each stakeholder group:

  • What is the likely benefit?
  • What is the likely harm?
  • What is the scale (how many people, how significantly)?

Then: Is the net effect positive? Who bears disproportionate cost to generate that net positive?

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.
