Async patterns + +- **One `async` function = one logical operation**; split orchestration (`loadUserAndOrders`) from low-level calls (`fetchUser`). +- **Parallelism**: `Promise.all` for independent tasks; **sequential** `await` only when order or data dependency requires it. +- **Timeouts and cancellation**: use `AbortController` for fetch when the codebase supports it; document fire-and-forget only when truly intentional (e.g. analytics). +- **Retries**: centralize retry/backoff in a helper or library—do not copy-paste retry loops across files. + +--- + +## 4.

Use when the user asks for help writing commit messages or reviewing staged changes. + +# Code Review +description: Review code for quality, security, and best practices following team standards. Use when reviewing pull requests, code changes, or when the user asks for a code review. +``` + +--- + +## Core Authoring Principles + +### 1. Concise is Key + +The context window is shared with conversation history, other skills, and requests. Every token competes for space. + +**Default assumption**: The agent is already very smart. Only add context it doesn't already have. + +Challenge each piece of information: +- "Does the agent really need this explanation?" +- "Can I assume the agent knows this?" +- "Does this paragraph justify its token cost?" + +**Good (concise)**: +```markdown +## Extract PDF text + +Use pdfplumber for text extraction: + +\`\`\`python +import pdfplumber + +with pdfplumber.open("file.pdf") as pdf: + text = pdf.pages[0].extract_text() +\`\`\` +``` + +**Bad (verbose)**: +```markdown +## Extract PDF text + +PDF (Portable Document Format) files are a common file format that contains +text, images, and other content. To extract text from a PDF, you'll need to +use a library. There are many libraries available for PDF processing, but we +recommend pdfplumber because it's easy to use and handles most cases well... +``` + +### 2. Keep SKILL.md Under 500 Lines + +For optimal performance, the main SKILL.md file should be concise. Use progressive disclosure for detailed content. + +### 3. Progressive Disclosure + +Put essential information in SKILL.md; detailed reference material in separate files that the agent reads only when needed. + +```markdown +# PDF Processing + +## Quick start +[Essential instructions here] + +## Additional resources +- For complete API details, see [reference.md](reference.md) +- For usage examples, see [examples.md](examples.md) +``` + +**Keep references one level deep** - link directly from SKILL.md to reference files. Deeply nested references may result in partial reads. + +### 4. Set Appropriate Degrees of Freedom + +Match specificity to the task's fragility: + +| Freedom Level | When to Use | Example | +|---------------|-------------|---------| +| **High** (text instructions) | Multiple valid approaches, context-dependent | Code review guidelines | +| **Medium** (pseudocode/templates) | Preferred pattern with acceptable variation | Report generation | +| **Low** (specific scripts) | Fragile operations, consistency critical | Database migrations | + +--- + +## Common Patterns + +### Template Pattern + +Provide output format templates: + +```markdown +## Report structure + +Use this template: + +\`\`\`markdown +# [Analysis Title] + +## Executive summary +[One-paragraph overview of key findings] + +## Key findings +- Finding 1 with supporting data +- Finding 2 with supporting data + +## Recommendations +1. Specific actionable recommendation +2. Specific actionable recommendation +\`\`\` +``` + +### Examples Pattern + +For skills where output quality depends on seeing examples: + +```markdown +## Commit message format + +**Example 1:** +Input: Added user authentication with JWT tokens +Output: +\`\`\` +feat(auth): implement JWT-based authentication + +Add login endpoint and token validation middleware +\`\`\` + +**Example 2:** +Input: Fixed bug where dates displayed incorrectly +Output: +\`\`\` +fix(reports): correct date formatting in timezone conversion + +Use UTC timestamps consistently across report generation +\`\`\` +``` + +### Workflow Pattern + +Break complex operations into clear steps with checklists: + +```markdown +## Form filling workflow + +Copy this checklist and track progress: + +\`\`\` +Task Progress: +- [ ] Step 1: Analyze the form +- [ ] Step 2: Create field mapping +- [ ] Step 3: Validate mapping +- [ ] Step 4: Fill the form +- [ ] Step 5: Verify output +\`\`\` + +**Step 1: Analyze the form** +Run: \`python scripts/analyze_form.py input.pdf\` +... +``` + +### Conditional Workflow Pattern + +Guide through decision points: + +```markdown +## Document modification workflow + +1. Determine the modification type: + + **Creating new content?** → Follow "Creation workflow" below + **Editing existing content?** → Follow "Editing workflow" below + +2. Creation workflow: + - Use docx-js library + - Build document from scratch + ... +``` + +### Feedback Loop Pattern + +For quality-critical tasks, implement validation loops: + +```markdown +## Document editing process + +1. Make your edits +2. **Validate immediately**: \`python scripts/validate.py output/\` +3. If validation fails: + - Review the error message + - Fix the issues + - Run validation again +4. **Only proceed when validation passes** +``` + +--- + +## Utility Scripts + +Pre-made scripts offer advantages over generated code: +- More reliable than generated code +- Save tokens (no code in context) +- Save time (no code generation) +- Ensure consistency across uses + +```markdown +## Utility scripts + +**analyze_form.py**: Extract all form fields from PDF +\`\`\`bash +python scripts/analyze_form.py input.pdf > fields.json +\`\`\` + +**validate.py**: Check for errors +\`\`\`bash +python scripts/validate.py fields.json +# Returns: "OK" or lists conflicts +\`\`\` +``` + +Make clear whether the agent should **execute** the script (most common) or **read** it as reference. + +--- + +## Anti-Patterns to Avoid + +### 1. Windows-Style Paths +- ✅ Use: `scripts/helper.py` +- ❌ Avoid: `scripts\helper.py` + +### 2. Too Many Options +```markdown +# Bad - confusing +"You can use pypdf, or pdfplumber, or PyMuPDF, or..." + +# Good - provide a default with escape hatch +"Use pdfplumber for text extraction. +For scanned PDFs requiring OCR, use pdf2image with pytesseract instead." +``` + +### 3. Time-Sensitive Information +```markdown +# Bad - will become outdated +"If you're doing this before August 2025, use the old API." + +# Good - use an "old patterns" section +## Current method +Use the v2 API endpoint. + +## Old patterns (deprecated) +
+Legacy v1 API +... +
+``` + +### 4. Inconsistent Terminology +Choose one term and use it throughout: +- ✅ Always "API endpoint" (not mixing "URL", "route", "path") +- ✅ Always "field" (not mixing "box", "element", "control") + +### 5. Vague Skill Names +- ✅ Good: `processing-pdfs`, `analyzing-spreadsheets` +- ❌ Avoid: `helper`, `utils`, `tools` + +--- + +## Skill Creation Workflow + +When helping a user create a skill, follow this process: + +### Phase 1: Discovery + +Gather information about: +1. The skill's purpose and primary use case +2. Storage location (personal vs project) +3. Trigger scenarios +4. Any specific requirements or constraints +5.

nested paths like **`settings/general`**, **`order-listing/:id`**, **`pricing-plan`**, etc. + +**Pattern**: **Route-based code splitting** at page granularity; add new routes by extending the **`routes`** array and importing a new lazy page. + +### L5 — Embedded shell (`ShopifyAppProvider`) + +- Reads **`shopinfo`** from Redux: onboarding status **`spld_onboarding_status`**, **`charge_approve`**. +- **Redirect priority**: if **`charge_approve === '0'`** → force **`usage-based-pricing`**;

uses **`lodash-es`**, **`safeJsonParse`** for string columns that may contain malformed JSON. + +**Pattern**: **Feature slices** per domain; async logic in **thunks**; components subscribe with **`useSelector`** / dispatch with **`useDispatch`**. + +### L8 — HTTP layer (`ODD_fetchData` in `utils/common.js`) + +- Prefixes paths with **`NODE_BASE_PATH`** (API mount). +- Appends **`odd_ref=1`** query flag on every request. +- Sends header **`authentication`**: Redux **`shopinfo.shopInfo.token`**, or **`await config.SHOPIFY.idToken()`** when available (matches backend **`verify.js`** expecting base64 JWT in **`Authentication`**). +- Supports **JSON**, **urlencoded**, and **FormData** bodies. +- On failure returns **`{ _fail: true, error }`** instead of throwing (call sites check **`response._fail`**). +- Logs client errors via **`create_logs`** (console in development). + +**Pattern**: **Single fetch wrapper** keeps auth and URL construction consistent; services stay thin. + +### L9 — Services + +- **`shopService.js`**, **`productService.js`**, etc., call **`ODD_fetchData`** / **`graphqlCall`** with specific paths (e.g. **`/shipping-price`**, settings endpoints). +- Some calls hit **third-party** promotion/marketing URLs—treat as **integration boundaries** and keep credentials out of source where possible. + +**Pattern**: One service module per aggregate (shop, product, order, onboarding). + +### L10 — Forms and validation + +- **Formik** (`useFormik`, **`FormikProvider`**) in settings pages (e.g. **`TextSettings.jsx`**). +- **Yup** available for schema validation (project dependency). +- **`SaveBarContext`** coordinates “dirty” state with navigation. + +**Pattern**: **Large settings screens** pair Redux-fetched data with Formik **`initialValues`** reset after fetch (see comments in **`shopinfoSlice`** / widget settings). + +### L11 — UI kit + +- **`src/ui`**: composable components (Table, Modal, Banner, Toast, DateField, DragAndDrop, FullEventCalendar pieces, …). +- **Storybook** stories colocated (`*.stories.jsx`). + +**Pattern**: Prefer **`src/ui`** for new controls; document variants in Storybook. + +### L12 — Advanced UI + +- **`@dnd-kit`** for sortable lists (see **`DragAndDrop`**). +- **Google Maps** scripting appears in route-related settings (dynamic script load, map overlays)—isolate script loading and teardown in hooks/callbacks. + +--- + +## Example: adding a new settings page (checklist) + +1.

Semantic Selectors +```typescript +// Resilient to changes +await page.click('button:has-text("Submit")') +await page.click('[data-testid="submit-button"]') +``` + +### ❌ WRONG: No Test Isolation +```typescript +// Tests depend on each other +test('creates user', () => { /* ... */ }) +test('updates same user', () => { /* depends on previous test */ }) +``` + +### ✅ CORRECT: Independent Tests
