Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

SkillSpector: 3 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

What it costs to keep this loaded
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 | $0.00234 | $0.05342 |
| Opus 5 | $0.00117 | $0.02671 |
| Sonnet 5 | $0.00047 | $0.01068 |
| Haiku 4.5 | $0.00023 | $0.00534 |
Grade A, and why
blockchain-infrastructure scanned grade A with 1 finding 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.

Blockchain Infrastructure
Purpose
Guide blockchain infrastructure operations: node deployment, RPC infrastructure, smart contract CI/CD, monitoring, MEV infrastructure, and key management. Covers production-grade deployment patterns for all major blockchain networks.
Agent Protocol
Trigger
"blockchain deploy", "node deployment", "archive node", "validator node", "RPC infrastructure", "blockchain RPC", "JSON-RPC load balancing", "smart contract CI/CD", "forge CI", "hardhat CI", "blockchain monitoring", "Prometheus blockchain", "Grafana blockchain", "Forta", "Tenderly", "devnet", "testnet", "blockchain environment", "mainnet deploy", "contract verification", "blockchain DevOps", "MEV infrastructure", "builder", "relay", "Flashbots", "MEV relay", "block building", "KMS", "HSM", "key management blockchain", "Fireblocks", "HSM blockchain", "validator key management", "searcher infrastructure"
Input Context
- Blockchain networks to support
- Node types (archive/full/validator)
- Infrastructure provider (bare-metal/cloud/K8s)
- Scale requirements (RPC load, number of chains, validators)
- Security requirements (key management, access control, compliance)
- Budget constraints
Output Artifact
Infrastructure architecture specification including: deployment topology, provisioning configuration, CI/CD pipeline, monitoring stack, and operations runbooks.
Response Format
- Deployment topology: node type, infrastructure sizing, network requirements, geographic distribution
- Provisioning: Ansible/Terraform/K8s configuration, secrets management, upgrade strategy
- CI/CD pipeline: test → build → verify → deploy → monitor flow with security gates
- Configuration: environment-specific parameters, chain settings, multi-env strategy
- Monitoring & alerting: metrics, dashboards, SLOs, runbooks, escalation
Completion Criteria
- Node deployment topology includes: sizing, network, storage, and HA strategy
- Provisioning automation covers: initial setup, upgrades, backups, disaster recovery
- CI/CD pipeline includes: contract testing, static analysis, deployment, verification, monitoring
- Monitoring covers: node health, chain health, infrastructure health, security events
- Runbooks document: deploy, upgrade, rollback, incident response procedures

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.
- 5d ago First seen · 579 lines · 234 tokens per session scan A 670ce72b8696
blockchain-infrastructure is a skill published in the GitHub repository j4flmao/agent-skills (22 stars, last pushed 3d ago), licensed MIT. It adds 234 tokens to every session and 5,342 once invoked, about $0.0012 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
