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 | $0.00093 | $0.02605 |
| Opus 5 | $0.00046 | $0.01303 |
| Sonnet 5 | $0.00019 | $0.00521 |
| Haiku 4.5 | $0.00009 | $0.00261 |
Grade A, and why
platform-custom-application-generate 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 4d 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.
How it starts
The opening of the file, as written. The whole thing — 216 lines — stays where its author put it; the contents beside it link to each section on GitHub.
When to Use This Skill

- Create professional, branded application identity with custom colors and branding
- Override standard actions with custom Lightning pages for enhanced user experience
- Enable profile-specific experiences through profile action overrides

- fullName: API name of the application
- label: Display name of the application
- uiType: Always "Lightning" for modern apps
- navType: CRITICAL - Choose based on user requirements and workflow patterns
- "Standard": DEFAULT for general business applications (e.g., sales, marketing, operations)
- "Console": ONLY when workflow requires managing multiple records simultaneously with split-view or multi-tab workspace (e.g., customer service, call centers, support operations)

- isNavTabPersistenceDisabled: Tab persistence setting (default: false)
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.
