salesforce-lwc

Router for the 83 SfSkills `lwc` skill packages. Lightning Web Components: reactivity, wire adapters, component communication, accessibility, performance, security and Jest testing. Use when the request mentions LWC, Lightning Web Component, wire, @api, @track, lightning-record-form, shadow DOM, Jest, Lightning Message Service, Aura migration, Lightning page. Finds and opens the exact skill package to read; it does not contain the guidance itself.

Salesforce lwc — SfSkills domain router

Lightning Web Components: reactivity, wire adapters, component communication, accessibility, performance, security and Jest testing.

83 skill packages live under ${CLAUDE_PLUGIN_ROOT}/skills/lwc/<slug>/SKILL.md. They are not loaded — reach them by path, on demand.

Generated by scripts/build_plugin.py. Do not hand-edit.

How to find the right skill

Three mechanisms, listed in order of reliability on a fresh install. Use the first one that is available; do not stop at a guess.

1. The shipped roster (always works, no setup). Read references/skill-index.md next to this file. It lists every lwc skill package with a one-line gloss, generated from registry/skills.json. Scan it and pick by name.

2. The MCP server (fast, needs the sfskills-mcp server connected). Call the search_skill tool with the user's phrasing and domain: "lwc". It returns ranked skill ids. get_skill then returns the package contents.

3. The search CLI (fast, needs a locally built index).

python3 "${CLAUDE_PLUGIN_ROOT}/scripts/search_knowledge.py" "<the user's question>" --domain lwc --json

This needs vector_index/, which is not shipped — it is gitignored and must be built once per clone:

cd "${CLAUDE_PLUGIN_ROOT}" && python3 -m pip install -r requirements.txt && python3 scripts/build_index.py

If the command errors or reports Coverage: NONE, fall back to mechanism 1 rather than telling the user the topic is uncovered.

Then read the package. Open the exact ${CLAUDE_PLUGIN_ROOT}/skills/<domain>/<slug>/SKILL.md the lookup returned, plus its references/gotchas.md and references/llm-anti-patterns.md. Do not answer from this router: it is a map, not the territory.

Featured entry points

Curated starting points when the request is broad or the lookup is ambiguous. This is a shortlist, not the catalogue — the roster at references/skill-index.md has all 83.

  • ${CLAUDE_PLUGIN_ROOT}/skills/lwc/component-communication/SKILL.md — parent/child, events, and when to reach for Lightning Message Service
  • ${CLAUDE_PLUGIN_ROOT}/skills/lwc/wire-service-patterns/SKILL.md — @wire, reactive parameters, and refreshing cached data
  • ${CLAUDE_PLUGIN_ROOT}/skills/lwc/lifecycle-hooks/SKILL.md — connected/rendered/disconnected and the work that belongs in each
  • ${CLAUDE_PLUGIN_ROOT}/skills/lwc/lwc-performance/SKILL.md — render cost, wasted reactivity, and the LWC side of a slow page
  • ${CLAUDE_PLUGIN_ROOT}/skills/lwc/lwc-security/SKILL.md — Lightning Web Security, sanitisation, and safe use of API data
  • ${CLAUDE_PLUGIN_ROOT}/skills/lwc/lwc-accessibility/SKILL.md — keyboard, focus and screen-reader behaviour as acceptance criteria
  • ${CLAUDE_PLUGIN_ROOT}/skills/lwc/lwc-testing/SKILL.md — Jest setup, mocking wire adapters, and asserting rendered output
  • ${CLAUDE_PLUGIN_ROOT}/skills/lwc/lwc-error-boundaries/SKILL.md — containing a component failure instead of blanking the page

Decision trees

Read the tree before activating a skill when the request could be solved more than one way, and cite the branch that decided it.

  • ${CLAUDE_PLUGIN_ROOT}/standards/decision-trees/performance-tuning.md — the LWC render branch, for any "the page is slow" report

Canonical templates

Do not hand-roll an idiom that already exists. Copy from ${CLAUDE_PLUGIN_ROOT}/templates/lwc/ and rename in the consuming project; never edit the template in place.

  • ${CLAUDE_PLUGIN_ROOT}/templates/lwc/jest.config.js
  • ${CLAUDE_PLUGIN_ROOT}/templates/lwc/component-skeleton
  • ${CLAUDE_PLUGIN_ROOT}/templates/lwc/patterns
  • ${CLAUDE_PLUGIN_ROOT}/templates/lwc/README.md — the full list

Run-time agents for this domain

Invoke one of these subagents when the ask is a whole workflow rather than a single question:

  • lwc-auditor — Accessibility + performance + security audit of an LWC bundle
  • lwc-builder — Generate a Lightning Web Component bundle
  • lwc-debugger — Diagnose a live LWC failure

Rules

  1. Answer from the opened lwc package, never from this router.
  2. Cite the skill id and, where one applied, the decision-tree branch.
  3. Never claim a topic is uncovered without pasting lookup output.
  4. Never deploy to an org.

概要と使いどころ

acceptance-criteria-given-when-then

無料

Use this skill when writing test-first, behavior-driven acceptance criteria in Given/When/Then format for a Salesforce user story. Covers happy path, edge cases, negative paths, permission boundaries, and data-state preconditions so the AC block can drive UAT scripts and Apex test design downstream. Trigger keywords: given when then, gherkin, behavior driven AC, test first acceptance criteria, scenario outline, BDD acceptance criteria. NOT for the user-story format itself (use admin/user-story-writing-for-salesforce). NOT for UAT script writing (use admin/uat-test-case-design). NOT for Apex test method generation (use agents/test-class-generator). NOT for high-level UAT planning (use admin/uat-and-acceptance-criteria). More triggers: acceptance criteria record, ac_id, req_id on a criterion, artefact under test, negative case for a rule-type requirement, no-match fall-through criterion, oracle for a Then clause, test type apex flow manual, criteria linter, check_ac_format.py, --manifest-dir.

activity-and-task-patterns

無料

Task and Event objects: polymorphic WhatId/WhoId, Activity object model, ActivityHistory vs OpenActivity, activity timeline customization, bulk task creation, Einstein Activity Capture boundaries. NOT for turning on EAC or calendar sync — use admin/einstein-activity-capture-setup. NOT for Email-to-Case — use admin/case-management-setup. Covers ActivitiesSettings metadata, enableActivities, shared Task/Event custom fields and FLS, TaskStatus value sets, Shared Activities and TaskRelation/EventRelation, recurring and child activities, and partial-success bulk DML on Task.

agent-action-error-handling

無料

Design Invocable Apex actions that return deterministic, agent-friendly errors instead of surfacing raw exceptions to the LLM. NOT for authoring the action itself — @InvocableMethod schema, labels, security context — use agentforce/custom-agent-actions-apex. NOT for the Apex tests that force each error branch — use agentforce/agent-action-unit-tests.

agent-action-input-slot-extraction

無料

Use when designing how an Agentforce agent extracts structured input parameters (slots) from a user's natural-language utterance to invoke an action. Triggers: 'agent extract date from user', 'agent action argument extraction', 'agentforce slot filling', 'agent invocable input mapping', 'agent fails to fill required parameter'. NOT for action authoring (use agentforce/agent-actions) or for prompt-template variable binding (use agentforce/prompt-builder-templates).

agent-action-unit-tests

無料

Apex test patterns for @InvocableMethod agent actions: per-reason-code branch coverage, bulk safety, callout mocking, deterministic assertions. NOT for testing whether the agent routes to the right topic or answers well — use agentforce/agent-testing-and-evaluation. NOT for designing the error envelope the tests assert on — use agentforce/agent-action-error-handling.

agent-actions

無料

Designing or reviewing Agentforce actions: Flow actions, Apex invocable actions, prompt-template actions, action naming, input and output contracts, confirmation requirements, and safe error behavior. Triggers: 'agent actions', 'build an agent that can look up an order', 'make the agent able to check order status', 'give the agent a capability', 'agent that can retrieve a record', 'flow action for agent', 'agent invocable action', 'action schema design'. NOT for writing the Apex class itself — use agentforce/custom-agent-actions-apex. NOT for the reason_code error envelope that stops an agent retry loop — use agentforce/agent-action-error-handling.
