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.

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 | $0.00152 | $0.03402 |
| Opus 5.5 | $0.00061 | $0.01361 |
| Sonnet 5.5 | $0.00030 | $0.00680 |
| Haiku 4.5 | $0.00015 | $0.00340 |
Grade A, and why
b2c-custom-api-development scanned grade A 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 1mo 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Custom API Development Skill
This skill guides you through developing Custom APIs for Salesforce B2C Commerce. Custom APIs let you expose custom script code as REST endpoints under the SCAPI framework.
Tip: If
b2cCLI is not installed globally, usenpx @salesforce/b2c-cliinstead (e.g.,npx @salesforce/b2c-cli code deploy).
Scope & grounding
This skill provides CLI-specific workflows and quickstart patterns for Custom API development. It covers OpenAPI 3.0 contract structure, OAuth scope configuration, cartridge-path resolution rules, and circuit breaker behavior. However, platform-specific validation rules, operational limits, security scheme requirements, and Script API integration patterns can drift across Commerce Cloud releases. Before answering questions that reference specific API versions or framework behavior, or before emitting code the user will run, confirm current platform specifics against the official documentation via b2c docs search / b2c docs read (CLI) or docs_search / docs_read (MCP). The official documentation is the authoritative source for Custom API contract specifications, runtime behavior, and B2C Commerce platform details not covered here.

What ships with it
4 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.
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.
