A test runner for DCS, a distributed storage system, covering its control service, host agent, storage daemon, and live clusters.

Use it to run unit, integration, chaos, filesystem, virtual-machine, API smoke, load, and scenario tests.

It provides ready-made checks for testing DCS changes locally, in CI, or against running environments.

Install

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.

Clone the repo

git clone --depth 1 https://github.com/Kevin-Liu-01/Agent-Machines

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	$0.00041	$0.00840
Opus 5	$0.00020	$0.00420
Sonnet 5	$0.00008	$0.00168
Haiku 4.5	$0.00004	$0.00084

Measured 10d ago against content hash b9bd9da730f8, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-10, from the pricing page.

Security

Grade B, and why

dcs-test scanned grade B with 1 finding 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 10d 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.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

How it starts

The opening of the file, as written. The whole thing — 84 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Context

Test hub: apps/cloud/apps/dcs/src/tests/README.md
Local profile runner: apps/cloud/apps/dcs/src/tests/cmd/dcs-check/
Live API smoke runner: apps/cloud/apps/dcs/src/tests/cmd/dcs-smoke/
Scenario/load runner: apps/cloud/apps/dcs/src/tests/cmd/dcs-gauntlet/
Remote Linux/KVM runner: pnpm dcs testbox

Profiles

Run the cheapest command that proves the changed invariant:

dcs-check unit [--scope controlplane|host-agent|storage-daemon|all]
dcs-check integration [--scope controlplane|host-agent|storage-daemon|all]
dcs-check kwok
dcs-check chaos
dcs-check chaos-compaction
dcs-check kvm
dcs-check fuse [--suite all|sanity|pjdfstest|git|npm|rust-compile|c-compile|go-compile|data-integrity|concurrent|fsstress|xfstests|xfstest-general]
dcs-check full

Live API verification:

DEDALUS_API_KEY=... dcs-smoke --env=dev
DEDALUS_API_KEY=... dcs-smoke --base https://dev.dcs.dedaluslabs.ai --iterations 2

Load and scenario drills:

DEDALUS_API_KEY=... dcs-gauntlet scale --base https://dev.dcs.dedaluslabs.ai --count 20
DEDALUS_API_KEY=... dcs-gauntlet ramp --base https://dev.dcs.dedaluslabs.ai --count 20
DEDALUS_API_KEY=... dcs-gauntlet compaction-drain --base https://dev.dcs.dedaluslabs.ai

Dispatching

When the user invokes /dcs-test without arguments, run:

go run ./apps/cloud/apps/dcs/src/tests/cmd/dcs-check unit

When a profile is specified, run exactly that profile through dcs-check, dcs-smoke, or dcs-gauntlet. Prefer go run ./apps/cloud/apps/dcs/src/tests/cmd/<tool> inside the repo unless the binary is already installed.

Remote Linux/KVM

For profiles that need Linux, /dev/kvm, or /dev/fuse, use the typed testbox CLI:

pnpm dcs testbox run "cargo build --release -p dm-host-agent -p dm-storage-daemon -p dm-bake -p dm-guest-agent"
pnpm dcs testbox run "sudo ./target/release/dm-check --iters 2"
pnpm dcs testbox run "go run ./apps/cloud/apps/dcs/src/tests/cmd/dcs-check kvm"

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.

dcs-test is a skill published in the GitHub repository Kevin-Liu-01/Agent-Machines (27 stars, last pushed today), licensed MIT. It adds 41 tokens to every session and 840 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
