Prime Frontend: Load Frontend Context

Objective

Build targeted understanding of the frontend codebase by analyzing its structure, components, and conventions. Loading only frontend context keeps the context window light on complex full-stack codebases. If external task references are provided, load them first so the analysis is anchored to the actual work.

Process

Step 0: Load External Context

Run this step BEFORE the codebase analysis. It accepts optional arguments: [jira-issue-keys] [confluence-page-ids].

• Jira keys may be a single key (ACC-2) or comma-separated (ACC-2,ACC-3).
• Confluence page ids are numeric page ids.

If Jira issue keys are provided:

1. Call mcp__atlassian__getAccessibleAtlassianResources to obtain the cloudId.
2. For each Jira key, call mcp__atlassian__getJiraIssue with that cloudId, the issue key, and responseContentFormat: "markdown".
3. Treat the returned issue summary, description, and acceptance criteria as the task context for everything that follows.

If Confluence page ids are provided:

1. Call mcp__atlassian__getConfluencePage for each page id with contentFormat: "markdown" (use the cloudId from above, fetching it via mcp__atlassian__getAccessibleAtlassianResources if it was not already retrieved).
2. Treat the returned page content as supporting context (specs, design docs, requirements).

If no arguments are provided: Skip this step entirely and proceed to Step 1.

Briefly summarize any external context loaded before continuing — this frames the rest of the priming.

1. Locate the Frontend

List all tracked files to find the frontend root:

!git ls-files

Common frontend roots: frontend/, client/, web/, src/ (when project is frontend-only), app/ (Next.js). Identify the correct root before proceeding.

2. Read Frontend Documentation

• Read CLAUDE.md or similar global rules file (for project-wide conventions)
• Read any README inside the frontend root
• Read .claude/references/frontend-component-best-practices.md if it exists — it contains project-specific component conventions

3. Identify Key Frontend Files

Based on the structure, read:

• Main entry point (main.tsx, index.tsx, app/layout.tsx, pages/_app.tsx, etc.)
• Routing configuration (router.tsx, routes.ts, app/ directory for Next.js)
• Global state setup (store, context providers)
• Shared component library root (components/, ui/)
• Core configuration (package.json, tsconfig.json, vite.config.ts, next.config.ts)
• One or two representative feature components to internalize the established patterns

Skip files outside the frontend root unless they define a shared type or contract the frontend depends on.

4. Understand Current Frontend State

Check recent frontend-relevant activity:

!git log -10 --oneline

!git status

Note any open changes in the frontend directory.

Output Report

Provide a concise summary covering:

External Task Context (if loaded)

• Jira issue(s): key, title, one-line goal, acceptance criteria
• Confluence page(s): title and what they specify

Frontend Overview

• Framework and major libraries (React, Vue, Next.js, Tailwind, etc.)
• Component patterns observed (atomic design, feature folders, etc.)
• State management approach

Directory Map

• Frontend root and key sub-directories with one-line purpose each

Conventions

• Naming conventions, file co-location rules
• Styling approach
• Testing framework and conventions observed

Current State

• Active branch, recent frontend changes
• Any immediate concerns (missing types, deprecated patterns, etc.)

Make this summary easy to scan - use bullet points and clear headers.
