What it does

Prime Frontend is an agent skill from coleam00/skills. Primes the agent with focused understanding of the frontend portion of the codebase — components, routing, state management, and styling — without loading unrelated backend code. Use at the start of a session when the work is scoped to UI or client-side features. Optionally pulls external task context from Jira issues and Confluence pages first.

Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Frontend & Design, covering State management. It works with Jira, Confluence and Model Context Protocol. The repository describes itself as: The agent skills I actually use to build software with coding agents. The PIV loop, planning, worktrees, and the meta-skills for building your own AI Layer. The licence is MIT.

When your agent uses it

  • Tasks that involve State management

Example prompts

  • “Use the prime-frontend skill to prime the agent with focused understanding of the frontend portion of the codebase — components, routing, state…”
  • “/prime-frontend”

Workflow steps

5 steps, taken from the step headings in SKILL.md.

  1. Load External Context
  2. Locate the Frontend
  3. Read Frontend Documentation
  4. Identify Key Frontend Files
  5. Understand Current Frontend State

What it can do on your machine

Read from SKILL.md and the folder at commit 847be08. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • git

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Prime Frontend loads about 1k tokens when it runs. Until then it costs about 91 tokens; SKILL.md has 469 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~91
When it runs · the whole SKILL.md, loaded when a task matches
~1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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
Show full SKILL.md (196 more words)Show less
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.
