Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 27 findings, up to high
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 →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00040 | $0.04127 |
| Opus 5.5 | $0.00016 | $0.01651 |
| Sonnet 5.5 | $0.00008 | $0.00825 |
| Haiku 4.5 | $0.00004 | $0.00413 |
Grade A, and why
reskill-usage 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 1mo 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 — 420 lines — stays where its author put it; the contents beside it link to each section on GitHub.
reskill Usage Guide
reskill is a Git-based package manager for AI agent skills. It provides declarative configuration (skills.json + skills.lock), flexible versioning, and multi-agent support for installing, managing, and sharing skills across projects and teams.
Requirements: Node.js >= 18.0.0
CLI usage: If reskill is installed globally, use it directly. Otherwise use npx reskill@latest:
npm install -g reskill # Global install
npx reskill@latest <command> # Or use npx directly (no install needed)
When to Use This Skill
Use this skill when the user:
- Wants to install, update, or manage AI agent skills
- Mentions
skills.json,skills.lock, or reskill-related concepts - Wants to publish a skill to a registry
- Asks about supported install formats (GitHub, GitLab, HTTP, OSS, registry, etc.)
- Encounters reskill-related errors or needs troubleshooting
- Wants to set up a project for skill management
- Asks about multi-agent skill installation (Cursor, Claude Code, Codex, etc.)
AI Agent Execution Rules
AI agents cannot respond to interactive prompts mid-command. Always add -y to commands that support confirmation prompts (install, uninstall, publish) to prevent the command from hanging.
# Correct — will not hang
reskill install github:user/skill -y
reskill uninstall skill-name -y
reskill publish -y
# Wrong — will hang waiting for confirmation
reskill install github:user/skill
reskill uninstall skill-name
Quick Start
# Initialize a new project
npx reskill@latest init
# Install a skill
npx reskill@latest install github:anthropics/skills/skills/frontend-design@latest
# List installed skills
npx reskill@latest list

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.
- 1mo ago First seen · 420 lines · 40 tokens per session scan A e74d33914917
reskill-usage is a skill published in the GitHub repository kanyun-inc/reskill (60 stars, last pushed 1mo ago), licensed MIT. It adds 40 tokens to every session and 4,127 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-08-30.
