skaffold-testing

skaffold-testing is a skill for Claude Code from laurigates/claude-plugins. It costs 40 tokens per session (1,210 once invoked), scanned A, original, MIT.

A guide to testing container images and deployed applications in Skaffold, a tool for developing and deploying containerised applications. It covers checks before deployment and verification afterward.

In plain words
What is it for?
Use it to configure container-structure tests, custom image checks, security scans, and post-deployment verification in Skaffold pipelines.
Why use it?
It catches invalid image contents or failed deployments before they reach users, and failed checks can block deployment.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter. Also seen: names the TodoWrite tool.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is - ./tests/structure/*.yaml.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

  • high Tool Misuse · line 35
    Tool parameters are crafted to achieve unintended or unsafe behavior. Parameter abuse can bypass intended safety checks (e.g. shell=True, --force, dangerous glob patterns).
    Fix: Validate all tool parameters against an allowlist. Reject dangerous parameter values (shell=True, --force, -rf /) and use safe defaults.

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

skaffold-testing scanned grade A 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.

Unrestricted tool accesslowExcessive agency

A wildcard tool grant or "run any command" leaves no least-privilege boundary at all.

| **custom** | Run arbitrary commands | None (uses `$IMAGE` env var) |

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

When to Use This Skill

Use this skill when... Use another skill instead when...
Configuring container-structure-tests Writing Dockerfiles (use container skills)
Adding security scans to Skaffold pipelines General Skaffold build/deploy (use skaffold-development)
Setting up post-deploy verification Unit testing application code
Validating image contents pre-deploy Kubernetes manifest authoring

Testing Lifecycle

Build -> Test -> Deploy -> Verify
          ^                  ^
     Pre-deploy         Post-deploy
Stage Purpose Runs During
test Validate images before deployment dev, run, test
verify Validate deployment works correctly dev, run, verify

Failed tests block deployment. Use --skip-tests to bypass.

Test Stage Overview

Two mechanisms for pre-deploy validation:

Type Purpose Tool Required
structureTests Validate image contents container-structure-test binary
custom Run arbitrary commands None (uses $IMAGE env var)

Container Structure Tests

Validate image contents without running the container.

Configuration

apiVersion: skaffold/v4beta11
kind: Config
test:
  - image: my-app
    structureTests:
      - ./tests/structure/*.yaml
    structureTestsArgs:
      - --driver=tar      # Faster, no Docker daemon needed
      - -q                # Quiet output

Test Types Summary

Type Purpose Key Fields
commandTests Verify binaries work command, args, expectedOutput, exitCode
fileExistenceTests Verify files present/absent path, shouldExist, permissions, uid, gid
fileContentTests Validate file contents path, expectedContents, excludedContents
metadataTest Validate image config envVars, user, entrypoint, cmd, exposedPorts, workdir

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.

skaffold-testing is a skill published in the GitHub repository laurigates/claude-plugins (59 stars, last pushed today), licensed MIT. It adds 40 tokens to every session and 1,210 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 2 findings (unrestricted tool access, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-06.
