What is 04-skill-api-tests?

A project rule for generating executable API tests in Kotlin with Ktor and JUnit. Ktor is a Kotlin framework for network applications, and JUnit is a tool for running tests.

It helps write tests for the /api-tests workflow using the ApiRequestBaseJson wrapper, JUnit 5 assertions, and Allure test IDs. Allure is a tool for linking and reporting test results.

It gives API test work a defined format instead of leaving request wrappers, assertions, and test tracking conventions to guesswork. API tests check whether software endpoints respond as expected.

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.

Per session 0 Nothing until a file matches its globs; then the whole rule loads.

When invoked 138 The whole file, excluding the scripts and references it only reads on demand.

Origin original No closer match found in the catalogue.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00000	$0.00138
Opus 5	$0.00000	$0.00069
Sonnet 5	$0.00000	$0.00028
Haiku 4.5	$0.00000	$0.00014

Security

Grade A, and why

04-skill-api-tests 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.

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.
