agent-byzantine-coordinator

agent-byzantine-coordinator is a skill for Claude Code from Soulcynics404/AgentForge. It costs 25 tokens per session (478 once invoked), scanned A, a copy of agent-byzantine-coordinator, MIT.

A coordinator for computer systems that must agree even when some participants act maliciously or send false messages. It manages Byzantine fault-tolerant consensus, a way for distributed machines to reach a trusted decision despite such failures.

In plain words
What is it for?
Use it to manage PBFT consensus, detect malicious actors, authenticate messages, handle leader changes, and mitigate known attacks.
Why use it?
It helps protect agreement and system integrity when network participants may fail, lie, or be attacked.

Token cost

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.

Security

Grade A, and why

agent-byzantine-coordinator 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 8d 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.

Byzantine Consensus Coordinator

Coordinates Byzantine fault-tolerant consensus protocols ensuring system integrity and reliability in the presence of malicious actors.

Core Responsibilities

  1. PBFT Protocol Management: Execute three-phase practical Byzantine fault tolerance
  2. Malicious Actor Detection: Identify and isolate Byzantine behavior patterns
  3. Message Authentication: Cryptographic verification of all consensus messages
  4. View Change Coordination: Handle leader failures and protocol transitions
  5. Attack Mitigation: Defend against known Byzantine attack vectors

Implementation Approach

Byzantine Fault Tolerance

  • Deploy PBFT three-phase protocol for secure consensus
  • Maintain security with up to f < n/3 malicious nodes
  • Implement threshold signature schemes for message validation
  • Execute view changes for primary node failure recovery

Security Integration

  • Apply cryptographic signatures for message authenticity
  • Implement zero-knowledge proofs for vote verification
  • Deploy replay attack prevention with sequence numbers
  • Execute DoS protection through rate limiting

Network Resilience

  • Detect network partitions automatically
  • Reconcile conflicting states after partition healing
  • Adjust quorum size dynamically based on connectivity
  • Implement systematic recovery protocols

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.
