What it does

Vastai Install Auth is an agent skill from jeremylongshore/tons-of-skills-marketplace. Install the supported Vast.ai CLI and establish a least-privilege authentication boundary without leaking or persisting the wrong key. Use when bootstrapping a workstation, CI runner, or automation account. Trigger with: "install Vast.ai", "configure VASTAPIKEY", "create a scoped Vast.ai key".

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/official-docs.md`). Compatibility notes: Requires a Vast.ai account, an approved secret store, and Linux, macOS, WSL, or Python 3.9+.

It sits in Backend & APIs, covering Authentication. The repository describes itself as: Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com. The licence is MIT.

When your agent uses it

  • Bootstrapping a workstation
  • Automation account
  • With: install Vast.ai
  • Configure VASTAPIKEY

Example prompts

  • “install Vast.ai”
  • “configure VASTAPIKEY”
  • “create a scoped Vast.ai key”
  • “/vastai-install-auth”

Requirements

  • Python 3
  • A credential in VAST_API_KEY
  • Compatibility (from SKILL.md): Requires a Vast.ai account, an approved secret store, and Linux, macOS, WSL, or Python 3.9+.
  • Pre-approved tools (allowed-tools): Read, Grep, Write, Edit

Workflow steps

5 steps, taken from the step headings in SKILL.md.

  1. Select the install channel
  2. Place the credential
  3. Create least privilege
  4. Verify positive and negative paths
  5. Plan rotation

What it can do on your machine

Read from SKILL.md and the folder at commit cfae287. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Grep
    • Write
    • Edit

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • docs.vast.ai
    • github.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • VAST_API_KEY

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

  • Compatibility

    Requires a Vast.ai account, an approved secret store, and Linux, macOS, WSL, or Python 3.9+.

    From compatibility in the SKILL.md frontmatter.

Context cost

Vastai Install Auth loads about 1.1k tokens when it runs, and up to ~1.4k if it reads all its reference files. Until then it costs about 79 tokens; SKILL.md has 457 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~79
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.4k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Vast.ai CLI Authentication Boundary

Overview

Install from the provider-supported channel, choose file-backed versus environment-backed authentication by runtime, and prove that the key can perform only the intended operations. The current CLI migrates legacy key files into the XDG configuration location.

Prerequisites

  • Named workload owner and classified workstation, CI, container, or service runtime
  • Permission inventory covering search, instance, user, billing, machine, and team operations
  • Approved secret store plus a rotation and revocation owner

Instructions

Step 1: Select the install channel

Use the managed installer on Linux, macOS, or WSL when an isolated runtime is desired. Use the vastai PyPI package for Windows or Python SDK work; record the installed version.

Step 2: Place the credential

For an interactive workstation, let vastai set api-key write ~/.config/vastai/vast_api_key or the corresponding XDG configuration path. For CI or containers, inject VAST_API_KEY; the environment value takes precedence and avoids a key file.

Step 3: Create least privilege

Build a permission file containing only the categories and endpoint constraints the workload needs, then create a named scoped key. Do not use a full-access console key for shared automation.

Step 4: Verify positive and negative paths

Run vastai show user --raw, one required operation, and one operation expected to be denied. Preserve only status, key ID, and permission evidence.

Step 5: Plan rotation

Create and verify the replacement before deleting the old key. Revoke immediately if a key, command trace, or artifact may have exposed its value.

Authentication

Every API request requires a key. Treat VAST_API_KEY, the XDG key file, and the legacy ~/.vast_api_key location as secrets; never print key values or copy them into receipts.

Tool Discipline

Use Read and Grep to inspect manifests, configuration, provider output, and existing tests before proposing a mutation. Use Write or Edit only for the approved plan, implementation, test, or redacted receipt; do not create, update, destroy, or fund Vast.ai resources without explicit operator approval.

Output

  • Install channel and exact CLI/SDK version
  • Scoped permission manifest with positive and expected-denial results
  • Redacted rotation, revocation, and rollback receipt

Return runtime, install channel, key ID, granted categories, verification outcomes, and credential owner.

Examples

A CI deployer receives misc, user_read, instance_read, and instance_write without billing or team access; its key is injected as a masked environment secret and deleted after replacement validation.
