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 | $0.00041 | $0.01920 |
| Opus 5.5 | $0.00016 | $0.00768 |
| Sonnet 5.5 | $0.00008 | $0.00384 |
| Haiku 4.5 | $0.00004 | $0.00192 |
Grade B, and why
linkerd-patterns scanned grade B with 2 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 1mo 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.
Downloads and executes remote codemediumSupply chain
curl | sh runs whatever the server returns today, which is not necessarily what it returned when this was reviewed.
curl --proto '=https' --tlsv1.2 -sSfL https://run.linkerd.io/install | sh Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
curl --proto '=https' --tlsv1.2 -sSfL https://run.linkerd.io/install | sh This is a copy
84% identical to linkerd-patterns — 14 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.
How it starts
The opening of the file, as written. The whole thing — 312 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Linkerd Patterns
Production patterns for Linkerd service mesh - the lightweight, security-first service mesh for Kubernetes.
When to Use This Skill
- Setting up a lightweight service mesh
- Implementing automatic mTLS
- Configuring traffic splits for canary deployments
- Setting up service profiles for per-route metrics
- Implementing retries and timeouts
- Multi-cluster service mesh

2. Key Resources
| Resource | Purpose |
|---|---|
| ServiceProfile | Per-route metrics, retries, timeouts |
| TrafficSplit | Canary deployments, A/B testing |
| Server | Define server-side policies |
| ServerAuthorization | Access control policies |
Templates
Template 1: Mesh Installation

# Verify installation
linkerd check
# Install viz extension (optional)
linkerd viz install | kubectl apply -f -
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.
- 1mo ago First seen · 312 lines · 41 tokens per session scan B 695e6fa308fb
linkerd-patterns is a skill published in the GitHub repository NOMARJ/sigil (6 stars, last pushed 11d ago), licensed Apache-2.0. It adds 41 tokens to every session and 1,920 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it B with 2 findings (downloads and executes remote code, makes network calls). It is 84% identical to linkerd-patterns, differing in 14 lines, and is treated as a copy.
