Wasp is a full-stack web framework for building React and Node.js applications with declarative code, while Prisma handles database access. It is for developers who want built-in features such as authentication, background jobs, email, RPC, type safety, and deployment in one application framework.
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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00019 | $0.01162 |
| Opus 5 | $0.00010 | $0.00581 |
| Sonnet 5 | $0.00004 | $0.00232 |
| Haiku 4.5 | $0.00002 | $0.00116 |
Grade A, and why
crossposting 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 5d 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 — 97 lines — stays where its author put it; the contents beside it link to each section on GitHub.
MDX Conversion Script
Converts a Wasp blog MDX file to clean markdown, HTML, and Medium-ready chunks. Output is saved to .claude/skills/crossposting/scripts/output/.
npx tsx .claude/skills/crossposting/scripts/convert-mdx.ts <path-to-mdx-file> [--publish-devto] [--update-devto <id>] [--upload-videos]
Output files (always written):
<slug>.md— clean markdown (for DEV.to)<slug>.html— HTML (for Medium preview/reference)<slug>-medium-chunks.json—{ title: string, chunks: string[] }pre-split at<h2>boundaries, pre-escaped for JS template literals
Flags:
--publish-devto— POST as draft to DEV.to (requiresDEVTO_API_KEY)--update-devto <id>— PUT to existing DEV.to article (requiresDEVTO_API_KEY)--upload-videos— upload local .mp4s to YouTube (unlisted), embed as{% youtube URL %}liquid tags
Env vars: DEVTO_API_KEY (from https://dev.to/settings/extensions), YOUTUBE_CLIENT_ID + YOUTUBE_CLIENT_SECRET (saved in 1password for the users).
Notes:
canonical_urlis auto-generated from MDX filename →wasp.sh/blog/...- Without
--upload-videos, local .mp4 videos become plain links
YouTube Setup (one-time, human steps)
- Create Google Cloud project → enable YouTube Data API v3 → create OAuth 2.0 Desktop credentials
- Add
YOUTUBE_CLIENT_IDandYOUTUBE_CLIENT_SECRETto~/.zshrc - Run
npx tsx .claude/skills/crossposting/scripts/upload-youtube.ts --auth→ authorize in browser (select @wasplang channel if prompted) - Refresh token stored in
~/.youtube-upload-tokens.json - Check channel:
npx tsx .claude/skills/crossposting/scripts/upload-youtube.ts --whoami. Wrong channel? Delete token file and re-auth.
Crossposting to Dev.to
Use --publish-devto or --update-devto <id> flags. Requires DEVTO_API_KEY.
Crossposting to Medium
Paste HTML into Medium's editor via Chrome DevTools MCP. The user must be logged in to Medium using email login (not google oauth) with [email protected].
What ships with it
4 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.

crossposting is a skill published in the GitHub repository wasp-lang/wasp (18,718 stars, last pushed yesterday), licensed MIT. It adds 19 tokens to every session and 1,162 once invoked, about $0.0001 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.
