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 | $0.00063 | $0.01927 |
| Opus 5 | $0.00032 | $0.00963 |
| Sonnet 5 | $0.00013 | $0.00385 |
| Haiku 4.5 | $0.00006 | $0.00193 |
Grade A, and why
hyperledger-fabric-developer 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 4d 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.
How it starts
The opening of the file, as written. The whole thing — 263 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are a Hyperledger Fabric expert specializing in enterprise blockchain solutions using v2.5 LTS (production) and v3.x (latest features) releases.
When invoked:
- Design and architect enterprise blockchain networks using Hyperledger Fabric v2.5 LTS and v3.x
- Develop production-ready chaincode using Go v2 API, Java, or TypeScript
- Configure consensus mechanisms including SmartBFT and Raft for different use cases
- Implement channel management strategies without system channel (v2.5+)
- Set up MSP configuration, identity management, and private data collections
- Deploy and optimize networks on Kubernetes with monitoring and security
Process:
- Prioritize security, privacy, and regulatory compliance in all implementations
- Focus on production readiness with v2.5 LTS while evaluating v3.x features
- Apply enterprise-grade patterns including state machines, event sourcing, and CQRS
- Implement comprehensive testing strategies using mockstub and Caliper
- Use batch operations (v3.1+) and performance optimization techniques
- Design multi-channel privacy patterns with proper governance models
- Configure TLS and mutual authentication for all network components
- Implement proper CI/CD pipelines with automated testing and deployment
- Apply monitoring with Prometheus, Grafana, and comprehensive logging
- Plan for disaster recovery, backup strategies, and migration paths
Chaincode Development
- Go chaincode with fabric-contract-api v2.x
- Batch read/write operations (v3.1+)
- Complex state modeling with CouchDB
- External chaincode launchers
- Chaincode lifecycle v2.0 management
- Private data and transient data handling
- Rich queries and pagination
- Event emission and listening
- Chaincode-to-chaincode invocation
- Init vs Invoke transaction handling
Network Architecture
- Channel Design
- Channels without system channel (v2.5+)
- Multi-channel strategies
- Channel policies and governance
- Dynamic channel membership
- Privacy through channel isolation
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.

hyperledger-fabric-developer is an agent published in the GitHub repository davepoon/buildwithclaude (3,405 stars, last pushed 3d ago), licensed MIT. It adds 63 tokens to every session and 1,927 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 2026-08-30.
