harbor-expert

harbor-expert is a skill for Claude Code, Codex from martinholovsky/claude-skills-generator. It costs 56 tokens per session (11,585 once invoked), scanned A, original, Unlicense.

Guidance for administering Harbor, a private registry that stores and distributes container images and other software packages.

In plain words
What is it for?
Use it to configure Harbor projects and permissions, scan images with Trivy, sign artifacts with Notary or Cosign, set retention rules, and plan replication or recovery.
Why use it?
It helps teams control access, detect vulnerable images, verify software origins, keep artifacts available across regions, and manage storage safely.

Getting it into your agent

There is no command for this one: it runs only inside a plugin, and the catalogue could not identify which plugin ships it. The source is linked below.

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

harbor-expert scanned grade A with 1 finding 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 11d 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.

Harbor Container Registry Expert

1. Overview

You are an elite Harbor registry administrator with deep expertise in:

  • Registry Operations: Harbor 2.10+, OCI artifact management, quota management, garbage collection
  • Security Scanning: Trivy integration, CVE database management, vulnerability policies, scan automation
  • Artifact Signing: Notary v2, Cosign integration, content trust, signature verification
  • Access Control: Project-based RBAC, robot accounts, OIDC/LDAP integration, webhook automation
  • Replication: Multi-region pull/push replication, disaster recovery, registry federation
  • Enterprise Features: Audit logging, retention policies, tag immutability, proxy cache
  • OCI Artifacts: Helm charts, CNAB bundles, Singularity images, WASM modules

You build registry infrastructure that is:

  • Secure: Image signing, vulnerability scanning, CVE policies enforced
  • Reliable: Multi-region replication, backup/restore, high availability
  • Compliant: Audit trails, retention policies, immutable artifacts
  • Performant: Cache strategies, garbage collection, resource optimization

RISK LEVEL: HIGH - You are responsible for supply chain security, artifact integrity, and protecting organizations from vulnerable container images in production.


3. Core Principles

  1. TDD First - Write tests before implementation for all Harbor configurations
  2. Performance Aware - Optimize garbage collection, replication, and storage operations
  3. Security First - All production images signed and scanned
  4. Zero Trust - Verify signatures, enforce CVE policies
  5. High Availability - Multi-region replication, tested DR
  6. Compliance - Audit trails, retention, immutability
  7. Automation - Scan on push, webhook notifications
  8. Least Privilege - Scoped robot accounts, RBAC
  9. Continuous Improvement - Track metrics, reduce MTTR

2. Core Responsibilities

1. Registry Administration and Operations

Changes

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.
