rhdh-test-placement

rhdh-test-placement is a skill for Claude Code, Codex from redhat-developer/rhdh-skills. It costs 162 tokens per session (999 once invoked), scanned A, original, Apache-2.0.

Advice for choosing where a permanent automated test should live in the Red Hat Developer Hub dynamic-plugin codebase. It compares repositories and test layers, from small unit tests to browser tests that may need a cluster.

In plain words
What is it for?
Use it to choose the repository and test level for a regression test, and to identify an existing test to model. It only advises and does not write or run tests.
Why use it?
It helps place a test in the least expensive environment that can still catch the problem, which can shorten feedback time and avoid unnecessary infrastructure.

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

rhdh-test-placement 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.

How it starts

The opening of the file, as written. The whole thing — 91 lines — stays where its author put it; the contents beside it link to each section on GitHub.

RHDH Test Placement

Advisory only. This skill answers where a lasting test belongs and what it should be modelled on. It does not write the test, run it, or change a file. The guiding rule: pick the cheapest environment that can actually catch the bug. Most plugin validation needs no cluster, and a growing share needs no Docker either.

Prerequisite: /grilling

Placement is a tradeoff, not a lookup. Cost, feedback time, coverage overlap, and what a layer can physically observe all pull in different directions, and the person asking usually has a preferred answer already.

Invoke /grilling before recommending a placement, and use the constraints it produces. If /grilling is not installed, stop: say the skill is required, name /setup-rhdh-skills install as the human's next step, and do not guess a placement in the meantime.

Scope

In scope Out of scope
Where a permanent regression or coverage test belongs Writing or running the test
Which repository and layer, and why not the others Fixing the defect under test
Which existing file to mirror A throwaway reproduction test
The rough feedback cost of each candidate Reviewing an RHDH Jira test plan

A one-off test that reproduces a defect and is then deleted is not this skill's subject; /rhdh-plugin-bug-fix owns that and removes the file before handing its change off. Come here for the durable test that stays behind afterwards.

Route by outcome

Outcome Load and follow
Recommend a repository, layer, harness, and template references/test-placement.md

references/test-placement.md carries the context questions to settle first, the repository decision table, the L1–L4b layer ladder, per-placement authoring notes with the file to copy, the commands that run each layer, and the things that are researched as not possible today.

Boundaries

  • /grilling is a hard prerequisite, not an option.
  • /rhdh-plugin-authoring owns writing the recommended test once the placement is settled.
  • /rhdh-plugin-bug-fix owns the throwaway reproduction and its evidence.
  • /rhdh-test-plan-review reviews an RHDH release test plan in Jira. That is a release-readiness review, not a placement question.

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.
