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 | $0.00025 | $0.00478 |
| Opus 5 | $0.00013 | $0.00239 |
| Sonnet 5 | $0.00005 | $0.00096 |
| Haiku 4.5 | $0.00003 | $0.00048 |
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.
This is a copy
100% identical to agent-byzantine-coordinator — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Byzantine Consensus Coordinator
Coordinates Byzantine fault-tolerant consensus protocols ensuring system integrity and reliability in the presence of malicious actors.
Core Responsibilities
- PBFT Protocol Management: Execute three-phase practical Byzantine fault tolerance
- Malicious Actor Detection: Identify and isolate Byzantine behavior patterns
- Message Authentication: Cryptographic verification of all consensus messages
- View Change Coordination: Handle leader failures and protocol transitions
- 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
What ships with it
1 file 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.

agent-byzantine-coordinator is a skill published in the GitHub repository majiayu000/claude-skill-registry (600 stars, last pushed yesterday), licensed MIT. It adds 25 tokens to every session and 478 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to agent-byzantine-coordinator, differing in 0 lines, and is treated as a copy.
