KAI-Scheduler: Instructions file for Codex

AGENTS.md

KAI-Scheduler AGENTS.md is an instructions file for Codex, OpenCode from kai-scheduler/KAI-Scheduler. It costs 2,107 tokens per session, scanned A, original, Apache-2.0.

A set of project instructions for developing KAI Scheduler, a Kubernetes scheduler designed to assign GPU resources for AI and machine-learning workloads. It documents build, formatting, linting, and testing commands.

In plain words
What is it for?
Use it when building services, formatting or linting Go code, running unit and integration tests, testing Helm charts, or running selected Ginkgo tests for scheduler components.
Why use it?
It gives contributors consistent commands and rules for checking changes. It also clarifies where Go tests belong and how to run focused integration tests.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md.

This is kai-scheduler/KAI-Scheduler's own configuration. It tells Codex and OpenCode how to work on KAI-Scheduler itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything KAI-Scheduler configures →

About the project

kai-scheduler/KAI-Scheduler is a Kubernetes scheduler that allocates GPU resources for AI and machine-learning workloads. It is used by Kubernetes cluster administrators to run interactive jobs, training, and inference while balancing resource use and fairness across teams, including in large GPU clusters. The catalogue add-ons provide instructions and skills for working with KAI Scheduler.

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

KAI-Scheduler AGENTS.md 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 7d 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.

KAI Scheduler - Agent Development Guide

KAI Scheduler is a Kubernetes scheduler optimized for GPU resource allocation in AI/ML workloads, built on kube-batch with a modular plugin architecture.

Build/Lint/Test Commands

Building

make build                    # Build all services (Docker-based)
make build-go SERVICE_NAME=scheduler  # Build single service

Linting

make lint                     # Run all linters (fmt, vet, golangci-lint)
make fmt-go                   # Format Go code
make vet-go                   # Run go vet

Testing

unit and integration tests
  • Test files MUST ALWAYS be in the same directory as code
  • Test files names MUST ALWAYS end in _test.go. Example: resolver_test.go
make test                     # Run all tests (unit + helm chart tests)

# Run a single test file
ginkgo -v ./pkg/scheduler/actions/allocate

# Run a specific test function
ginkgo -v --focus "TestHandleAllocation" ./pkg/scheduler/actions/allocate

# Run tests with Ginkgo (for integration tests)
ginkgo -v --focus "test name pattern" ./pkg/binder/controllers/integration_tests

# Run tests with envtest (requires setup-envtest)
make envtest
KUBEBUILDER_ASSETS="$(bin/setup-envtest use 1.34.0 -p path --bin-dir bin)" go test ./pkg/... -timeout 30m
E2E tests

E2E tests run against a real Kubernetes using kind cluster and are located in test/e2e/suites/.

# Run locally with Kind (recommended for development)
./hack/run-e2e-kind.sh                          # Full e2e suite
./hack/run-e2e-kind.sh --preserve-cluster       # Keep cluster after tests
./hack/run-e2e-kind.sh --local-images-build     # Build images locally

# Run specific test suites (requires cluster with KAI installed)
ginkgo -r --randomize-all ./test/e2e/suites/allocate
ginkgo -r --randomize-all --focus "quota" ./test/e2e/suites

# Run with verbose output and trace
ginkgo -r --randomize-all --trace -vv ./test/e2e/suites/preempt

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.
