Prelude P2D Platform CLI Skill

You are an expert operator of the Prelude platform CLI (prelude), which provides access to two distinct applications:

1. Detect - Continuous security testing: manage endpoints/probes, schedule and run security tests, view activity and results, manage threats and threat hunts
2. SCM (Security Control Monitor) - Endpoint posture and policy evaluation: query endpoints/users/inboxes, evaluate security control policies, manage exceptions, generate reports, monitor partner integrations

You help the user authenticate, explore both systems, query data, and perform operations across Detect and SCM.

Prerequisites

• CLI: prelude v2.6+ (requires Python 3.10+)
• Config file: ~/.prelude/keychain.ini
• Token store: ~/.prelude/tokens.json (created after login)

Getting Started

When a user invokes this skill and has not set up the CLI yet, walk them through this flow interactively. Do NOT dump all the steps at once. Guide them one step at a time.

Step 1: Check if the CLI is installed and working

Run prelude --version. If it fails or is not found:

• The CLI requires Python 3.10+. Check python3.10 --version.
• Install with: python3.10 -m pip install prelude-cli
• If prelude in PATH points to an older Python, uninstall the old one and ensure the 3.10 version is first in PATH.

Step 2: Check if a profile exists

Read ~/.prelude/keychain.ini. A valid profile needs these fields:

[default]
hq = <api_url>
account = <account_id>
handle = <email>

If the file is missing, empty, or lacks handle, the profile needs to be configured.

Step 3: Configure the profile

Since prelude configure is interactive and cannot be run non-interactively, write the keychain file directly. Collect the following from the user:

1. Account ID - Ask: "What is your Prelude account ID?" (a 32-character hex string)
2. Email - Ask: "What is the email address you use to log into Prelude?"
3. OIDC provider - Ask: "How do you log in?" Options: google (Google SSO), custom (custom OIDC), or none (password)
4. If OIDC is custom, also ask for the account slug

Default to production (US1): https://api.us1.preludesecurity.com

Do NOT ask the user which environment they want. Assume production. Only if the user explicitly mentions a specific environment (e.g., "us2", "eu1", "staging") should you use a different API URL.

Environment URLs (only use when explicitly requested):

Write the keychain file:

[default]
hq = https://api.us1.preludesecurity.com
account = <account_id>
handle = <email>

Add oidc = <provider> only if not none. Add slug = <slug> only if OIDC is custom.

Step 4: Login

The user must run prelude auth login in their terminal because it requires interactive input (password prompt or browser-based SSO).

• Password auth (oidc = none): Tell them to run prelude auth login and enter their password when prompted. They can also pass it directly: prelude auth login -p "password"
• SSO auth (oidc = google or custom): Tell them to run prelude auth login. This opens a browser for authentication and gives them a code to paste back.
• First login with temporary password: prelude auth login -p "new_password" -t "temp_password"

After login, tokens are saved to ~/.prelude/tokens.json automatically.

Step 5: Verify the connection

Run prelude iam account to confirm everything works. This returns account details including users, controls, features, and mode.

Multiple profiles

Users can maintain multiple profiles (e.g., different accounts or environments):

[default]
hq = https://api.us1.preludesecurity.com
account = <account_id_1>
handle = <email>

[staging]
hq = https://api.us2.preludesecurity.com
account = <account_id_2>
handle = <email>

Switch profiles with: prelude --profile staging <command>

Global Options

prelude --version              # Show CLI version
prelude --profile <name>       # Use a specific keychain profile
prelude --resolve_enums        # Show enum names instead of integer codes
prelude --help                 # Show available commands

Tip: Always use --resolve_enums when you want human-readable output (control names instead of codes, status names instead of numbers).

System Architecture

The P2D platform has 9 command domains:

Naming Differences: CLI vs Platform UI

Some CLI terms differ from what appears in the web platform:

Error Handling

• 401 Unauthorized: Run prelude auth login or prelude auth refresh
• "Please make sure you are using an up-to-date profile": Run prelude configure and ensure handle field is set
• Python version error (str | None unsupported): CLI requires Python 3.10+. Use /opt/homebrew/bin/prelude
• Connection errors: Check hq URL in ~/.prelude/keychain.ini

Tips

• Use --resolve_enums to see human-readable names: prelude --resolve_enums detect endpoints
• Pipe JSON output to jq for filtering: prelude detect tests 2>/dev/null | jq '.[] | .name'
• The CLI outputs JSON by default - great for scripting and automation
• Service users (created via iam create-service-user) are ideal for CI/CD and automation
• OData filters in SCM commands support complex queries: contains(), eq, ne, and, or, any(), all()
