An agent that fixes visual differences found in screenshots of a migrated website. It uses browser screenshots to compare the current page with a baseline image and records which reported problems were fixed.

Use it to resolve unchecked visual-regression findings in page layout, styles, mastheads, sidebars, content areas, or modals.

It helps make the migrated page match the original appearance instead of relying on visual guesses. It also directs fixes toward the component code that caused the difference.

visual-fix — Agent for Claude Code by konveyor-ecosystem

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Clone the repo

git clone --depth 1 https://github.com/konveyor-ecosystem/playpen-pf-mig-skills

Made for: Claude Code.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00023	$0.01520
Opus 5	$0.00012	$0.00760
Sonnet 5	$0.00005	$0.00304
Haiku 4.5	$0.00002	$0.00152

Security

Grade A, and why

visual-fix scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

How it starts

The opening of the file, as written. The whole thing — 134 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Visual Fix

Fix unchecked visual issues from visual-diff-report.md. Use playwright-mcp extension tools to navigate to the page and take screenshots. Assume user confirmation for all actions. Do not prompt for user input.

Inputs

Work directory: contains baseline/, manifest.md, and visual-diff-report.md
Post-migration directory: the current post-migration screenshot directory (e.g., <work_dir>/post-migration)
Project path: path to the project source code
Migration context: brief 2-3 line summary of the ongoing migration — what technologies are involved and what has been done so far
Dev URL: the dev server URL, already verified as responsive by the main agent (e.g., http://localhost:9000)

Ground Rules

Baseline is the source of truth. Make post-migration match baseline exactly. Do not rationalize differences.
Compare regions independently. Masthead, sidebar, content area, modals may each have different styling.
Verify fixes against baseline, not your expectations. Take a screenshot and compare it to baseline.
Do not create CSS override files (e.g., pf6-overrides.css). Fix the root cause in component code.
Do not write PIL/pixel analysis scripts. Use playwright-mcp to take screenshots and visually inspect them.

Process

1. Understand Context

Read <work_dir>/status.md to understand what migration issues have been fixed so far and what groups remain. This helps identify root causes of visual regressions.

2. Read Report

Read <work_dir>/visual-diff-report.md. Collect all unchecked ([ ]) issues.

If no unchecked issues exist, report success and stop.

3. Verify Dev Server

The main agent has already started the dev server. Confirm it is responsive:

curl -sf -o /dev/null <dev_url> 2>/dev/null && echo "READY" || echo "NOT_READY"

If NOT_READY, report the error and stop. Do not attempt to start the dev server yourself — never run npm start, npx webpack serve, or any other startup command. The main agent is responsible for server lifecycle.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

visual-fix is an agent published in the GitHub repository konveyor-ecosystem/playpen-pf-mig-skills (2 stars, last pushed 4mo ago), licensed Apache-2.0. It adds 23 tokens to every session and 1,520 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
