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.

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 | $0.00043 | $0.00388 |
| Opus 5.5 | $0.00017 | $0.00155 |
| Sonnet 5.5 | $0.00009 | $0.00078 |
| Haiku 4.5 | $0.00004 | $0.00039 |
Grade A, and why
ae-ltd-mcp-foundry 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 today.
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.
What it actually says
AE.LTD MCP Foundry
What This Skill Does
Scaffolds and hardens MCP (Model Context Protocol) servers with strict contracts and validation. Niche gem source: model-context-protocol plugin from awesome-claude-code-toolkit.
- Scaffold new MCP servers with proper structure
- Add tools, resources, and prompts to existing servers
- Validate input/output with Zod (TS) or Pydantic (Python)
- Test happy-path and failure-path scenarios
Quick Start
User: "Create an MCP server for file operations"
→ Confirm context → Lock contracts → Scaffold → Validate → Test → Document
Workflow
-
Confirm server context. Path, language, transport (
stdioorsse), and whether this is new or existing. -
Lock contract first. Define tool names, descriptions, and input/output schema before writing handlers.
-
Scaffold or extend. Create server structure (if new), then add tool/resource registration and handler wiring.
-
Validate hard. Use Zod (TS) or Pydantic (Python). Reject invalid input early with useful error text.
-
Test one happy-path and one failure-path per tool. Prefer runnable tests or lightweight CLI/integration checks.
-
Document usage for agent callers. Keep descriptions explicit so models can invoke tools correctly.
Guardrails
- Keep tool names unique and verb-oriented.
- Do not ship tools with ambiguous parameter names.
- Every required input must be validated.
- Error responses must be actionable, not generic.
- If multiple transports are possible, start with
stdiounless user asks otherwise.
What ships with it
2 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.

ae-ltd-mcp-foundry is a skill published in the GitHub repository aegntic/cldcde (11 stars, last pushed today), licensed MIT. It adds 43 tokens to every session and 388 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 2026-11-05.

tauri-django-react
Agents should invoke this skill for Tauri + Django + React desktop apps, especially backend lifecycle, CORS/auth, frontend integration, mandatory light/dark theming, German/English i18n, build packaging, dual desktop/web deployment, Rust commands, and platform-specific gotchas.
shoo-auth
Use when evaluating, implementing, reviewing, or debugging Shoo auth (shoo.dev) Google sign-in in browser apps, including @shoojs/react, @shoojs/auth, hosted shoo.js, Convex custom JWT integration, PKCE callbacks, session checks, and server-side idtoken verification. Do not use for unrelated auth systems.
add-a-service
Scaffold a new service under services/ in the builders-stack monorepo. Use when something needs its own URL, port, or independent deploy. Covers the package, entrypoint, config, Tilt, deployment registry, and shared small-image build path.
wire-a-new-payment-provider
Add or swap a payment provider behind the @stack/payment adapter in the builders-stack monorepo. Use when integrating Stripe, Paddle, Lemon Squeezy, or any provider alongside or in place of the default Creem adapter. The whole point is that apps and the API never change — only the adapter implementation does. Covers…
api-fetch-wrapper
Wrap a public HTTP API (Open-Meteo weather as the demo) with credential handling, error normalisation, and a single retry on transient network failures. Demonstrates the production-shaped baseline for any "skill that calls an external service" — env-based secrets, structured error output, no leaked API keys in logs…
