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 | $0.00231 | $0.03107 |
| Opus 5 | $0.00115 | $0.01554 |
| Sonnet 5 | $0.00046 | $0.00621 |
| Haiku 4.5 | $0.00023 | $0.00311 |
Grade A, and why
experience-lds-best-practices-apply 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 12d 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.

Applying LDS Best Practices
Apply the Lightning Data Service guidelines to a Lightning Web Component. Three pillars: data consistency, referential integrity, and UIAPI vs Apex. Focused on the UI API path — GraphQL and upstream data-requirements analysis are handled out-of-band.
When to Use
- Reviewing a component's data layer for LDS compliance (hand-rolled forms, stringly-typed field names, un-synchronized Apex + LDS, Apex overuse).
- Implementing CRUD on standard or custom objects.
- Deciding between
getRecord,getRecords,createRecord,updateRecord,deleteRecord, base record form components, or Apex. - Fixing stale-data bugs after record mutation.
- Adding schema imports (
@salesforce/schema/...) to replace hard-coded field/object names.
Do NOT use this skill for:
- GraphQL query/mutation generation — handled out-of-band today.
- Upstream data-requirements discovery — handled out-of-band today.
- SLDS class / design-token work (use
design-systems-slds-apply). - Accessibility, security, or RTL review — those are separate passes run with their own tooling.
Prerequisites
- Component path.
- Understanding of the component's data operations (read / write / both) and whether Apex is already involved.
- Access to the org's schema for
@salesforce/schemaimports (Setup → Object Manager →<Object>→ Details → API Name; or, when GraphQL serves the read, an SDL pulled from the target org).
Knowledge Bases
- references/lds-expert.md — authoritative LDS knowledge (patterns, adapters, caching, mutation flows).
- references/lds-data-consistency.md — cache invalidation,
refreshApex,notifyRecordUpdateAvailable, wire result propagation. - references/lds-referential-integrity.md —
@salesforce/schemaimports, field constants, object-name resolution, and their propagation through refactors.
Per-adapter API reference — references/adapter-apis.md holds Syntax / Parameters / Returns / Usage for every UI API adapter, grouped by family (uiRecordApis, uiListsApis, uiRelatedListApis, uiObjectInfoApis). Each adapter is a # `<name>` block; grep for the backticked name (e.g. # `getRecord`) to jump to its entry. Read this before wiring an adapter; do not paraphrase from memory.
What ships with it
5 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.

experience-lds-best-practices-apply is a skill published in the GitHub repository forcedotcom/sf-skills (981 stars, last pushed 3d ago), licensed Apache-2.0. It adds 231 tokens to every session and 3,107 once invoked, about $0.0012 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.
