signadot-cli

A command-line guide for Signadot, a system for creating isolated test environments called sandboxes and routing requests to them.

In plain words
What is it for?
It helps create, update, inspect, and delete sandboxes, route groups, clusters, secrets, jobs, resource plugins, and smart tests. It also covers preview URLs and YAML templates.
Why use it?
It gives developers and platform engineers a way to manage temporary test environments and related resources from one CLI.

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

signadot-cli 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.

Signadot CLI

Help the user manage Signadot resources using the signadot CLI. If the user specifies a resource type ($ARGUMENTS), focus on that section. Otherwise, provide guidance based on what they're trying to accomplish.

Core Concepts

  • Sandbox: An isolated environment comprising forked workloads, local workloads, or virtual workloads plus ephemeral resources. Each sandbox gets a unique routing key for request routing.
  • Route Group: Dynamically groups sandboxes by label criteria and provides shared preview URLs. Useful for combining multiple sandboxes into a single test environment.
  • Preview URL: An authenticated URL that routes traffic to a specific sandbox or route group by automatically injecting the routing key.
  • Resource Plugin: A reusable template for provisioning ephemeral resources (databases, queues, etc.) within sandboxes.
  • Templates: YAML files with @{variable} directives, expanded at apply time with --set variable=value.

Configuration

The main configuration for the CLI is authentication (org and optionally api key) and configuration for signadot local.

The CLI reads $HOME/.signadot/config.yaml by default. Use --config to switch:

signadot --config ~/configs/staging.yaml sandbox list

See authentication below for authentication information and the signadot-local skill for local configuration.

Authentication

# Interactive browser login
signadot auth login

# API key login
signadot auth login --with-api-key <key>

# Check status
signadot auth status

# Logout
signadot auth logout

For CI, use environment variables: SIGNADOT_ORG and SIGNADOT_API_KEY.

Sandbox Management (alias: sb)

Create or Update a Sandbox

Write a YAML spec file and apply it:

# my-sandbox.yaml
name: my-sandbox
spec:
  cluster: my-cluster
  description: Testing new feature
  forks:
  - forkOf:
      kind: Deployment
      namespace: example
      name: my-app
    customizations:
      images:
      - image: example.com/my-app:dev-abcdef
        container: my-app
      env:
      - name: FEATURE_FLAG
        container: my-app
        operation: upsert
        value: "true"
  defaultRouteGroup:
    endpoints:
    - name: my-endpoint
      target: http://my-app.example.svc:8080

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.

signadot-cli is a skill published in the GitHub repository signadot/cli (8 stars, last pushed 13d ago), licensed Apache-2.0. It adds 56 tokens to every session and 3,107 once invoked, about $0.0003 per session on Opus 5. 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 2026-08-31.
