Constraint: Only use this skill when the user explicitly mentions "Stitch".
Purpose
This skill makes the Element Plus design spec executable in two modes:
- Prefix mode: output a paste-ready Hard constraints prefix for Stitch
[Context]. - Selector mode: output
CONTRACT_SELECTION_JSON_V1and then an assembled Stitch prompt that injects only the required component/state snippets.
Trigger Keywords
Prefer this skill when the user request includes any of:
element,element-plus,el-plus,element-ui
Chinese trigger keywords (only for triggering):
element 风格饿了么组件库后台管理系统(if context implies Element Plus)
Source of Truth
references/contract.mdreferences/examples.mdreferences/official.md
Output (STRICT)
Decide the mode by the user intent:
- If the user asks for beautify/polish/refine an existing screen, or asks for selector / JSON / contracts.include / states.include → use Selector mode.
- Otherwise → use Prefix mode.
Prefix mode
Return exactly one code block:
[Hard constraints prefix]
- Framework: Element Plus (Vue 3).
- Design Tokens:
- Colors: Primary=#409EFF (Blue), Success=#67C23A, Warning=#E6A23C, Danger=#F56C6C, Info=#909399.
- Typography: Font-family: "Helvetica Neue", Helvetica, "PingFang SC", "Hiragino Sans GB", "Microsoft YaHei", Arial, sans-serif.
- Radius: Small=2px, Base=4px, Round=20px.
- Component Contracts:
- Layout: Use <el-row :gutter="20"> and <el-col :span="...">. Container: <el-container>, <el-header>, <el-main>.
- Buttons: Use <el-button type="primary" plain/round>.
- Forms: Use <el-form>, <el-form-item>, <el-input>, <el-select>, <el-switch>, <el-checkbox>.
- Data: <el-table>, <el-descriptions>, <el-timeline>, <el-carousel>, <el-empty>.
- Cards: Use <el-card shadow="hover"> with #header slot.
- Icons: Use <el-icon><Edit /></el-icon> (from @element-plus/icons-vue).
- Navigation: <el-menu>, <el-breadcrumb>, <el-tabs>, <el-steps>.
- Feedback: Use ElMessage.success() for JS feedback, <el-alert>, <el-dialog>, <el-drawer>.
- Layout Invariants:
- Always use 24-column grid system.
- Use el-space for inline spacing.
Selector mode
Return exactly two code blocks, in this order, with no extra prose:
- Contract selection JSON:
{
"version": "CONTRACT_SELECTION_JSON_V1",
"designSystem": "element-plus",
"mode": "selector",
"contracts": { "include": [] },
"states": { "include": [] }
}
- Final Stitch prompt:
[Context]
(Paste Hard Constraints Prefix here)
(Add "Layout Invariants" from contract.md if beautifying)
[Layout]
(Describe the macro layout structure, e.g., "Admin Dashboard Layout with Sidebar")
[Components]
(Inject component snippets matching the JSON selection above)

When to use
When the user needs to select and execute a verifiable, recoverable professional workflow for the current request . Load this skill. First extract the goal, inputs, constraints, delivery format, and acceptance criteria from the request; the description summary is: Element Plus design spec for Stitch. Outputs hard-constraints prefix or selector JSON and assembled prompt.
Rules
- Read before write: first confirm the current state and real capabilities, then perform actions that change external state.
- Least privilege: use only the files, tools, accounts, and network scope required to complete the current step.
- Evidence first: when run results, resource IDs, versions, hashes, or test output are missing, clearly mark them as
NOT_VERIFIED。 - Idempotency first: retain request identifiers and phase state; when results are unclear, query first and do not retry blindly.
- Privacy and security: logs, examples, receipts, and error messages must not contain tokens, cookies, keys, or personally sensitive data.
Workflow
Step 1: Clarify intent
Confirm whether this skill matches the goal; if it is only an adjacent need, hand it off to a more precise skill.
Step 2: Perform prechecks
Confirm the goal, inputs, constraints, available tools, success criteria, and failure boundaries; if any key condition is unknown, stop at the read-only stage.
Step 3: Form a plan
List the tools to be called, the objects that will change, the success criteria, and the safe exit method after failure.
Step 4: Execute actions
Execute in minimal sufficient steps and record evidence at key state changes; retain an associable state or receipt for every external call.
Step 5: Verify delivery
Output the results, verification evidence, unfinished items, risks, and clear next steps, and state facts, inferences, and unverified items separately.
Validation checklist
- The skill trigger conditions match the user's intent, and no adjacent task was misrouted to this skill.
- The inputs, target objects, versions, and output locations are all clear, and no guessed values were used in place of required values.
- All write, paid, publishing, or irreversible actions are within the scope authorized by the user.
- The results have been verified with independent checks; "command succeeded" or "file exists" alone does not count as complete acceptance.
- The output includes actual evidence, failed/skipped items, remaining risks, and executable next steps.
Gotchas
- Treating the plan as the result: documentation or prompts are not the same as actual execution; the actual execution level must be indicated.
- Erroneous retry: a timeout or lost response may already have produced remote state; query first before deciding whether to retry.
- Implicit scope expansion: batch, full-scale, publishing, overwriting, and paid operations are not a natural extension of ordinary reads and writes.
- Version drift: when referencing external resources, record the version, tag, or commit; do not treat a mutable branch as release evidence.
- Stale evidence: caches, old screenshots, and historical tests cannot prove the current environment; refresh key evidence before delivery.
Non-applicability and boundaries
Do not exceed the scope given by the user; write, paid, publishing, and irreversible actions require explicit authorization. If the request requires another skill, do not copy its content; hand off by skill name and preserve the current task context.
