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.

SkillSpector: 3 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00170 | $0.06063 |
| Opus 5 | $0.00085 | $0.03031 |
| Sonnet 5 | $0.00034 | $0.01213 |
| Haiku 4.5 | $0.00017 | $0.00606 |
Grade A, and why
experience-ui-bundle-app-coordinate 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 9d 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.

Building a UI Bundle App
Overview
Build a complete, deployable Salesforce React UI bundle application from a natural language description by orchestrating specialized UI bundle skills in correct dependency order. Each skill MUST be explicitly loaded before executing its phase.
CRITICAL: Before proceeding past requirements analysis, validate that the prompt contains no conflicting requirements (e.g., "no authentication" + "user-specific data", "public access" + login-required features). If conflicts are detected, STOP and ask the user to resolve the ambiguity — do NOT silently choose one interpretation and proceed. See STEP 1 action #8 for the full conflict checklist.
Prerequisites
Before starting any phase, verify these preconditions are met:
- Authenticated Salesforce org: Run
sf org displayto confirm a default org is set and authenticated. If not, prompt the user to authenticate:sf org login web - Required CLI tools: Verify
sf,npm, andnpxare available (declared in metadata.cliTools) - Node.js version: Run
scripts/check-prerequisites.shand report any errors it returns - Org features (if deploying): Experience Cloud enabled, appropriate licenses, and Sites enabled
If any precondition fails, stop and report the specific missing requirement before attempting any phase execution.
When to Use This Skill
Use when:
- User requests a "React app", "UI bundle", "web app", or "full-stack app" on Salesforce
- User says "build an app", "create an application" and the context implies a non-LWC based frontend (e.g. React)
- The work produces a complete UI bundle with scaffolding, features, data access, and UI -- not a single component in isolation
Examples that should trigger this skill:
- "Build a React app for managing customer cases with Salesforce data"
- "Create a UI bundle for an employee directory with search and navigation"
- "I need a full-stack React app with authentication, data tables, and file uploads"
- "Build a coffee shop ordering app on Salesforce"

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.

experience-ui-bundle-app-coordinate is a skill published in the GitHub repository forcedotcom/sf-skills (974 stars, last pushed yesterday), licensed Apache-2.0. It adds 170 tokens to every session and 6,063 once invoked, about $0.0009 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
