linkerd

linkerd is a skill for Claude Code, Codex from G1Joshi/Agent-Skills. It costs 14 tokens per session (294 once invoked), scanned A, original, MIT.

A lightweight Kubernetes service mesh for managing communication between services. It provides encrypted service traffic, authorization policies, metrics, retries, and timeouts through small proxies.

In plain words
What is it for?
Use it to enable mutual TLS, monitor service success rates and latency, configure route retries and timeouts, and include virtual machines in the mesh.
Why use it?
It adds common networking and security controls without requiring each application to implement them. Its focus on low overhead can suit clusters where a larger mesh would be too costly or complex.

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

linkerd 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 9d 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.

What it actually says

Linkerd

Linkerd is a lightweight Service Mesh. It focuses on simplicity and performance (Rust-based proxies). v2.15 (2025) enables Mesh Expansion to VMs.

When to Use

  • Low Overhead: You want mTLS and Metrics but can't afford Istio's CPU tax.
  • Simplicity: "It just works". No complex configuration for basic features.
  • Security: Default-on mTLS and authorization policies.

Core Concepts

Micro-Proxy

Linkerd uses a specialized Rust proxy (not Envoy) that is tiny and fast.

Viz Extension

A dashboard and Prometheus instance pre-configured to show mesh metrics (Success Rate, Latency).

ServiceProfiles

Define retry logic and timeouts per route.

Best Practices (2025)

Do:

  • Use HA Mode: Run control plane in high-availability mode for production.
  • Automate Cert Rotation: Use cert-manager to rotate the mTLS root CA automatically.
  • Expand to VMs: Use the new 2.15 feature to include legacy databases in the mesh.

Don't:

  • Don't disable mTLS: It's verified automatically. Keep it on.

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.

linkerd is a skill published in the GitHub repository G1Joshi/Agent-Skills (12 stars, last pushed 7mo ago), licensed MIT. It adds 14 tokens to every session and 294 once invoked, about $0.0001 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 2026-09-03.
