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 | $0.00152 | $0.08232 |
| Opus 5 | $0.00076 | $0.04116 |
| Sonnet 5 | $0.00030 | $0.01646 |
| Haiku 4.5 | $0.00015 | $0.00823 |
Grade A, and why
israeli-cloud-cost-comparator 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 9d 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.

Israeli Cloud Cost Comparator
Instructions
Step 1: Understand the User's Cloud Requirements
Gather before comparing:
- Workload type: web app, API backend, data pipeline, ML training, static site, database
- Scale: traffic (requests/month), storage (GB/TB), compute (vCPU/RAM), and egress volume, which is the line item most often forgotten and, in the Israeli region, the largest cost difference
- Compliance: must the data stay in Israel? Any sector overlay (Bank of Israel supervision, health, government)?
- Budget: monthly, in NIS or USD, and whether pay-as-you-go or committed spend is preferred
- Technical stack: language, database, containerized or serverless
- Growth trajectory: startup scaling fast, SMB steady, or enterprise predictable. This decides whether a commitment is safe at all
- Existing credits and promotions: ask explicitly whether the user has active credits, free-tier benefits or promotional balances with ANY provider (AWS Activate, Google for Startups, Microsoft Founders Hub, GitHub Student Pack, hackathon or accelerator credits). Credits can flip the comparison and must be factored in
Step 2: Compare AWS Israel Region (il-central-1)
AWS launched the Israel (Tel Aviv) region il-central-1 in August 2023. Key details:
Available services in il-central-1:
- EC2 (compute), EBS (block storage), S3 (object storage)
- RDS (managed databases: PostgreSQL, MySQL, Aurora)
- Lambda (serverless), ECS/EKS (containers)
- ElastiCache (Redis/Memcached), DynamoDB
- CloudFront (CDN with Tel Aviv edge), Route 53
Pricing benchmarks (il-central-1 vs. eu-west-1 Ireland):
- EC2 instances carry a flat ~5% premium over eu-west-1. Measured August 2026 across all 324 shared Linux instance types present in both regions via the AWS Price List API: median 5.0%, range 4.3-5.9%. It does not vary by family (t3.medium 5.0%, m7i.xlarge 5.0%, r6i.xlarge 5.0%, g5.xlarge 5.0%). Do not model a 5-15% band and take the midpoint; that doubles the real gap.
- S3 storage is roughly equivalent
- Data transfer out is NOT the same globally, and it is the largest Israeli-region cost difference by far. Internet egress from il-central-1 is $0.110/GB for the first 10 TB/month against $0.090/GB from eu-west-1 and us-east-1, a 22% premium. Inter-region transfer OUT of Tel Aviv is $0.08/GB to every destination checked, against $0.02/GB out of Ireland, and the charge is asymmetric. Full tiers, destination list and the architectural consequence are in
references/cost-mechanics.md. - The Israeli-region cost story is a network story, not a compute story. Compute is a flat ~5% premium; network is 22% and 4x. A comparison that models a 10% compute premium and zero egress delta has it backwards on both counts. When to use il-central-1:
- Data residency requirements mandate Israeli hosting
- Latency-sensitive applications serving Israeli users (1-3 ms local vs. 45-65 ms to Western Europe)
- Financial services, healthcare, or government applications
- Compliance with Israeli Privacy Protection Authority regulations
What ships with it
9 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.

israeli-cloud-cost-comparator is a skill published in the GitHub repository skills-il/developer-tools (10 stars, last pushed today), licensed MIT. It adds 152 tokens to every session and 8,232 once invoked, about $0.0008 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.
