scaffold-skill

scaffold-skill is a skill for Claude Code, Codex from a-tokyo/aiworkspace. It costs 63 tokens per session (708 once invoked), scanned A, original, Apache-2.0.

A helper for creating new AI-agent skills with the correct folders and links for tools such as Cursor, Claude Code, and Codex.

In plain words
What is it for?
Use it to create workspace-wide or project-specific skills, validate their names, generate the starting template, and link them into supported tool directories.
Why use it?
It avoids manually creating skill files and prevents different coding tools from seeing inconsistent copies.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: reads .claude/ paths; mentions Claude Code; installed under .agents/ (shared by several agents).

SkillSpector: 2 findings, up to medium

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

  • medium Rogue Agent · line 6
    Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.
    Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.
  • medium Agent Snooping · line 22
    Skill enumerates or reads other installed skills. Access to other skills' SKILL.md files or the skills directory reveals prompt instructions, capabilities, and secrets that should be invisible to peer skills.
    Fix: Remove all code or instructions that list or read other skills' files or directories. Skills should operate independently; cross-skill access is a privilege escalation.

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

scaffold-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 2mo 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 — 86 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Scaffold Skill

Creates new skills using the workspace script, which handles name validation, directory placement, and symlinking to all AI tool directories.

Workflow

1. Decide scope

Ask the user if unclear.

  • Workspace-wide: stored in root-config/.agents/skills/, symlinked to the workspace root so all projects and AI tools (.agents/skills/, .claude/skills/, skills/) can discover it.
  • Project-specific: stored in <repo>/.agents/skills/, symlinked into that project's AI tool directories only.

2. Scaffold

Run from the workspace/ directory:

# Workspace-wide
npm run skills:create -- --name <skill-name>

# Project-specific
npm run skills:create -- --name <skill-name> --project <repo>

This validates the name, creates the directory with a template SKILL.md, and runs setup to symlink the skill into .claude/skills/ and skills/ so every AI tool can discover it.

Naming rules: lowercase letters, numbers, hyphens, underscores, and dots. Max 64 chars. Must start and end with a letter or number.

3. Write content

Do not write the SKILL.md content directly. Delegate to your IDE's skill-authoring guide for quality content and proper requirements gathering.

  1. Search your available skills for one named create-skill. Common locations:

    • Cursor: ~/.cursor/skills-cursor/create-skill/SKILL.md
    • Claude Code: ~/.claude/skills-cursor/create-skill/SKILL.md
    • Or check your available skills list for any skill with "create-skill" in the name or "skill" + "create" in the description.

  2. If found: Read it and follow its complete workflow from the start -- including any discovery or requirements-gathering phase (asking the user questions about purpose, triggers, format, etc.). Use the scaffolded SKILL.md as your starting point; the guide tells you how to fill it in.

  3. If not found: Edit the generated SKILL.md directly:

    • Replace the placeholder description with a specific, third-person description that includes both WHAT the skill does and WHEN to use it.
    • Replace the placeholder body with clear instructions and examples.
    • Keep the file under 500 lines.

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.
