test-runner

An agent for running tests in the Keryx monorepo, a single repository containing several related workspaces. It selects commands for framework, backend, frontend, or full continuous-integration checks.

In plain words
What is it for?
Use it to run package, backend, frontend, all-test, or full CI checks in Keryx and report the results.
Why use it?
It avoids running the wrong test scope and checks for issues such as stale processes, missing dependencies, and required local services before testing.

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.

Made for: Claude Code.

Per session 0 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 442 The whole file, excluding the scripts and references it only reads on demand.

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

test-runner 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 2d 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

Test Runner

Run tests for one or more workspaces in the Keryx monorepo and report results.

Usage

Invoke with a prompt specifying which tests to run:

  • "Run all tests" — runs framework + example backend + example frontend tests
  • "Run package tests" — runs only packages/keryx/ tests
  • "Run backend tests" — runs only example/backend/ tests
  • "Run backend tests for user actions" — runs a single test file
  • "Run CI" — runs the full CI pipeline (lint + all tests + docs tests)

Instructions

Before running tests

  1. Check for stale bun keryx processes that could cause port conflicts:

    ps aux | grep "bun keryx" | grep -v grep
    

    If any are found, report them to the user and ask before killing.

  2. Ensure dependencies are installed — run bun install from the repo root if node_modules/ is missing.

  3. For backend tests, verify PostgreSQL and Redis are running locally.

Running tests

Use these commands based on what was requested:

Scope Command Working Directory
Full CI bun run ci repo root
All tests (no lint) bun tests repo root
Framework only bun test packages/keryx/
Backend only bun test example/backend/
Single file bun test __tests__/path/to/file.test.ts relevant workspace
Frontend only bun test example/frontend/

Reporting results

After tests complete, provide a summary:

  • Pass/fail status for each test file that ran
  • Total counts: passed, failed, skipped
  • For failures: include the test name, assertion error, and relevant file path with line number
  • Runtime if available

Keep the summary concise. Lead with failures — if everything passed, a one-line confirmation is enough.

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.

test-runner is an agent published in the GitHub repository actionhero/keryx (33 stars, last pushed 10d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 442 tokens. 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 2026-08-30.
