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 | $0.03471 | $0.03471 |
| Opus 5 | $0.01736 | $0.01736 |
| Sonnet 5 | $0.00694 | $0.00694 |
| Haiku 4.5 | $0.00347 | $0.00347 |
Grade A, and why
n8n-Claude-Skill-Package CLAUDE.md 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 10d 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.

n8n Claude Skill Package
Standing Orders — READ THIS FIRST
Mission: Build a complete, production-ready skill package for n8n Workflow Automation and publish it under the OpenAEC Foundation on GitHub. This is your standing order for every session in this workspace.
How: Follow the 7-phase research-first methodology. Delegate ALL execution to agents. You are the ARCHITECT — you think, plan, validate, and delegate. Agents do the actual work.
What you do on session start:
- Read ROADMAP.md → determine current phase and next steps
- Read all core files (LESSONS.md, DECISIONS.md, REQUIREMENTS.md, SOURCES.md)
- Continue where the previous session left off
- If Phase 1 is incomplete → create the raw masterplan first
- If Phase 2+ → follow the methodology, delegating in batches of 3 agents
Quality bar: Every skill must be deterministic (ALWAYS/NEVER language), English-only, <500 lines, verified against official docs via WebFetch. No hallucinated APIs. No vague language.
End state: A published GitHub repo at https://github.com/OpenAEC-Foundation/n8n-Claude-Skill-Package with:
- All skills created, validated, and organized
- INDEX.md with complete skill catalog
- README.md with installation instructions and skill table
- Social preview banner (1280x640px) with OpenAEC branding
- Release tag (v1.0.0) and GitHub release
- Repository topics set (claude, skills, n8n, workflow-automation, ai, deterministic, openaec)
Reflection checkpoint: After EVERY phase/batch, pause and ask: Do we need more research? Should we revise the plan? Are we meeting quality standards? Update core files before proceeding.
Consolidate lessons: Any workflow-level insight (not tech-specific) should also be noted for consolidation back to the Workflow Template repo (C:\Users\Freek Heijting\Documents\GitHub\Skill-Package-Workflow-Template).
Masterplan template: When creating your masterplan in Phase 3, follow the EXACT structure from:
- Template:
C:\Users\Freek Heijting\Documents\GitHub\Skill-Package-Workflow-Template\templates\masterplan.md.template - Proven example:
C:\Users\Freek Heijting\Documents\GitHub\Tauri-2-Claude-Skill-Package\docs\masterplan\tauri-masterplan.md(27 skills, 10 batches, executed in one session)
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.
