b2c-logging

A guide to server-side logging in Salesforce B2C Commerce, an online-store platform. It explains message levels, categories, custom log files, and diagnostic context for tracing activity.

In plain words
What is it for?
Use it to add debug, information, warning, error, and critical messages; separate logs by functional area; write to named files; and trace related operations.
Why use it?
It makes application behavior and failures easier to inspect by putting useful messages in organized logs.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

b2c-logging 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.

Logging Skill

This skill guides you through implementing logging in B2C Commerce using the Logger and Log classes.

Overview

B2C Commerce provides a logging framework with:

Feature Description
Log Levels debug, info, warn, error, fatal
Categories Organize logs by functional area
Custom Files Write to dedicated log files
NDC Nested Diagnostic Context for tracing
BM Configuration Enable/disable levels per category

Log Levels

Level Method Description Default State
debug debug() Detailed debugging information Disabled (never on production)
info info() General information Disabled by default
warn warn() Warning conditions Always enabled
error error() Error conditions Always enabled
fatal fatal() Critical failures Always enabled, can send email

Basic Logging

Using Logger (Static Methods)

The Logger class provides static methods for quick logging:

var Logger = require('dw/system/Logger');

// Simple messages
Logger.debug('Debug message');
Logger.info('Info message');
Logger.warn('Warning message');
Logger.error('Error message');

// Messages with parameters (Java MessageFormat syntax)
Logger.info('Processing order {0} for customer {1}', orderNo, customerEmail);
Logger.error('Failed to process {0}: {1}', productId, errorMessage);

Using Log (Instance Methods)

The Log class provides instance-based logging with categories:

var Logger = require('dw/system/Logger');

// Get logger for a category
var log = Logger.getLogger('checkout');

log.debug('Cart contents: {0}', JSON.stringify(cart));
log.info('Checkout started for basket {0}', basketId);
log.warn('Inventory low for product {0}', productId);
log.error('Payment failed: {0}', errorMessage);
log.fatal('Critical checkout failure: {0}', errorMessage);

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
