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 | $0.00063 | $0.02285 |
| Opus 5 | $0.00032 | $0.01143 |
| Sonnet 5 | $0.00013 | $0.00457 |
| Haiku 4.5 | $0.00006 | $0.00229 |
Grade A, and why
adk-workshop-builder 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 7d 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.

Google ADK Workshop Builder Skill
Purpose
Automates the end-to-end creation of technical hands-on workshops focused on Google Agent Development Kit (ADK) and autonomous multi-agent systems. It provides standardized, production-ready curriculum and code skeletons across four major programming language tracks (Python, TypeScript/JavaScript, Go, Kotlin), enforcing best practices for agent planning, sub-agent delegation, tool bindings, and state persistence.
Pre-Flight Web Research Protocol: Before generating workshop materials, execute live web searches to verify current ADK SDK package versions and Gemini model tags (
gemini-3.7-flash,gemini-3.5-flash).

Core Agentic Architecture Patterns
When generating an ADK workshop, enforce the following three foundational architectural patterns:
1. Coordinator-Worker Multi-Agent Delegation Pattern
- Coordinator (Root Agent): Receives user queries, decomposes complex objectives into sub-tasks, and delegates to specialized sub-agents.
- Specialist Sub-Agents: Dedicated agents with narrow scopes and custom tools (e.g.
ResearchAgent,CodeExecutionAgent,ReviewerAgent).

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.

adk-workshop-builder is a skill published in the GitHub repository JAICHANGPARK/workshop-harness (5 stars, last pushed 6d ago), licensed MIT. It adds 63 tokens to every session and 2,285 once invoked, about $0.0003 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 2026-08-31.
