skill

skill is a skill for Claude Code, Codex from humanity4ai/project_human. It costs 0 tokens per session (108 once invoked), scanned A, original, MIT.

A template for documenting a skill: its purpose, boundaries, workflow, safety limits, and common mistakes.

In plain words
What is it for?
Writing or reviewing skill instructions, defining limits, describing workflows, recording assumptions, and specifying when to escalate uncertain situations.
Why use it?
It provides a clear structure for explaining what an add-on should do and for preventing unsupported or unsafe behavior.

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

skill 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 3d 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

Skill Name

Purpose

Describe what the skill does and why it exists.

Boundaries

  • Non-clinical support only
  • No diagnosis, treatment, or legal advice
  • Escalate crisis and safety-critical situations

Workflow

  1. Identify context and user intent.
  2. Apply the skill protocol.
  3. Return structured outputs.
  4. Declare assumptions and uncertainty.

Anti-patterns

  • Overconfident claims without evidence
  • Missing safety escalation when required
  • Ignoring cultural or contextual constraints
Files

What ships with it

5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

skill is a skill published in the GitHub repository humanity4ai/project_human (4 stars, last pushed 5d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 108 tokens. 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.
