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 | $0.00043 | $0.01792 |
| Opus 5.5 | $0.00017 | $0.00717 |
| Sonnet 5.5 | $0.00009 | $0.00358 |
| Haiku 4.5 | $0.00004 | $0.00179 |
Grade A, and why
consul 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 — 180 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Overview & Engine Architecture
Consul provides service discovery, health checking, a hierarchical KV store, and optional Connect service mesh (mTLS + intentions). Servers form a Raft quorum; client agents on nodes register services and answer DNS (*.service.consul) / HTTP catalog queries. In any shared environment treat ACLs as mandatory—bootstrap once, store the management token offline, issue least-privilege tokens to agents and sidecars. Put secrets in @vault, not Consul KV.

When to use / when not to
Use when
- Registering services with HTTP/TCP/gRPC checks so load balancers and apps resolve healthy instances only.
- Central non-secret config in KV; prepared queries / resolvers for failover.
- Service mesh intentions (allow/deny) with Connect proxies—often beside
@nomad.
Do not use when
- You need Kubernetes-native Service/Endpoints only and already run full K8s discovery →
@kubernetes. - The data is passwords, API keys, or certs →
@vault(Consul KV is for config, not secret source of truth). - Someone asks for a single Consul server “for prod simplicity” → refuse; require 3 or 5 voters.
What ships with it
2 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.

consul is a skill published in the GitHub repository alivirgo/Major-AI-Skills (2 stars, last pushed yesterday), licensed MIT. It adds 43 tokens to every session and 1,792 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-09-05.
