Wondel.ai Agent Skills is a collection of skills and guided workflows that give coding agents structured methods for business, marketing, UX, website, app, and software-development tasks. It is used with agents such as Claude Code, Codex, Cursor, OpenClaw, and other agents that support the agentskills.io format. The catalogue entries are the project's skills, plugins, instructions, and rule packaged for those agents.

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 | $0.00638 | $0.00638 |
| Opus 5.5 | $0.00255 | $0.00255 |
| Sonnet 5.5 | $0.00128 | $0.00128 |
| Haiku 4.5 | $0.00064 | $0.00064 |
Grade A, and why
cursorrules 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.

Wondel.ai Skills Repository
You are working in a collection of agent skills for Claude, Claude Code, Claude Cowork, Codex, Cursor, OpenClaw, Hermes Agent and other agentskills.io-compatible agents.
Repository Purpose
This repository contains specialized domain knowledge skills for AI agents. Each skill provides frameworks and methodologies for specific use cases (UX design, marketing, product strategy, etc.).
Strict Requirements
When Modifying Skills
-
ALWAYS bump version numbers in SKILL.md frontmatter when making changes:
- MINOR bump (e.g., 1.0.0 → 1.1.0) for new features or significant enhancements
- PATCH bump (e.g., 1.0.1 → 1.0.2) for bug fixes, typos, or small clarifications
-
YAML frontmatter is REQUIRED - Every SKILL.md must have:
--- name: skill-name description: What the skill does and when to use it (max 1024 chars, include trigger phrases) license: MIT metadata: author: wondelai version: "x.y.z" --- -
Name constraints:
- Max 64 characters
- Lowercase letters, numbers, hyphens only
- No start/end hyphens, no consecutive hyphens
- MUST match parent directory name exactly
-
Description requirements:
- Max 1024 characters
- Include specific trigger phrases and keywords
- Describe BOTH what it does AND when to use it

Adding New Skills
- Create folder:
{skill-name}/ - Create
SKILL.mdwith valid YAML frontmatter - Add to
README.mdwith description and examples - Add to
.claude-plugin/marketplace.jsonin appropriate collection
Code Style
- Use clear, semantic markdown
- Keep main SKILL.md concise (< 500 lines recommended)
- Move detailed content to
references/*.mdfiles - Use progressive disclosure: metadata → instructions → resources
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 · 81 lines · 638 tokens per session scan A e0b76a589655
cursorrules is a cursor rule published in the GitHub repository wondelai/skills (2,517 stars, last pushed 1mo ago), licensed MIT. It adds 638 tokens to every session, about $0.0026 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.
