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.
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.

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 | $0.00135 | $0.03602 |
| Opus 5 | $0.00068 | $0.01801 |
| Sonnet 5 | $0.00027 | $0.00720 |
| Haiku 4.5 | $0.00014 | $0.00360 |
Grade A, and why
mom-test 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 12d 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.

The Mom Test Framework
Framework for customer conversations that won't lead you astray, based on a fundamental truth: everyone is lying to you -- not maliciously, but because you're asking the wrong questions. The Mom Test provides rules for asking questions so good that even your mom can't lie to you.
Core Principle
Good customer conversations are about their life, not your idea. The moment you mention what you're building, people switch from sharing truth to performing politeness. Talk about their problems, their lives, and their existing behavior instead of pitching, and ask about specifics in the past, not hypotheticals about the future. Above all, talk less and listen more.
Scoring
Goal: 7/7. Score a conversation (or interview plan) by the seven-row Quick Diagnostic below: 1 point per row that passes.
- 6-7 = focused on their life and past behavior, concrete facts captured, a real commitment (time/reputation/money) secured, they talked 80%+, and beliefs got updated.
- 4-5 = some past-behavior facts but leaking into hypotheticals, compliments accepted as signal, or ending without an ask.
- <=3 = a pitch in disguise: leading questions, opinions and fluff, a polite zombie lead, no learning.
Always state the current score out of 7, name the failing diagnostic rows, and give the specific fix for each.
Framework Sections
1. The Mom Test Rules
Core concept: Three rules that make it impossible for even your most supportive loved ones to give you false validation, shifting conversations from opinion-gathering to fact-finding.
Why it works: People are unreliable predictors of their own future behavior, so opinions are worthless. Past behavior is the only reliable data and can genuinely inform product decisions.
Key insights:
- Rule 1: Talk about their life, not your idea -- never mention your solution until the end, if at all
- Rule 2: Ask about specifics in the past, not generics or hypotheticals about the future
- Rule 3: Talk less, listen more -- aim for them to speak 80% of the time
- A question fails the Mom Test if the answer is always "yes" regardless of whether the business will succeed
- Good questions could potentially destroy your currently imagined business
What ships with it
6 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.
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.

mom-test is a skill published in the GitHub repository wondelai/skills (2,138 stars, last pushed 12d ago), licensed MIT. It adds 135 tokens to every session and 3,602 once invoked, about $0.0007 per session on Opus 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.

dotnet-dependency
This skill should be used when investigating .NET project dependencies, understanding why packages are included, listing references, or auditing for outdated/vulnerable packages.
team-review
Review changed code for reuse, quality, and efficiency using a team of persistent named reviewers. This skill should be used when the user says "team review", "review with team", or wants parallel code review with persistent team members for follow-up questions. Similar to /subagent-review but reviewers persist after…
codex
Route a task to OpenAI's Codex CLI (codex exec) instead of doing it yourself. Use this skill ANY time the user names codex or types /codex — even for routine work Claude could handle, because the user is choosing to delegate. The intent: 'ask codex', 'have codex review/refactor this', 'check/validate with codex', 'see…
