What is managing-media?

A collection of implementation patterns for handling files and media in applications, including images, video, audio, and documents. It covers uploading, displaying, playing, and optimizing these files.

Use it to build drag-and-drop or resumable uploads, image galleries, video and audio players, PDF viewers, cloud-storage integrations, and accessible media features such as captions and transcripts.

It helps solve common problems such as large uploads, slow media loading, missing accessibility information, and inconsistent playback or viewing controls.

Install

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

Clone the repo

git clone --depth 1 https://github.com/ancoleman/ai-design-components

agentmods

npx agentmods add skills/ancoleman/ai-design-components/managing-media

Made for: Claude Code.

Or install ui-content-skills, the plugin that ships this one along with the rest of its 2 skills.

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	$0.00088	$0.02806
Opus 5	$0.00044	$0.01403
Sonnet 5	$0.00018	$0.00561
Haiku 4.5	$0.00009	$0.00281

Security

Grade A, and why

managing-media scanned grade A with 0 findings 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 9d ago.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/generate_mock_images.py, scripts/optimize_images.py, scripts/validate_media_accessibility.js), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Managing Media & Files

Purpose

This skill provides systematic patterns for implementing media and file management components across all formats (images, videos, audio, documents). It covers upload workflows, display patterns, player controls, optimization strategies, and accessibility requirements to ensure performant, accessible, and user-friendly media experiences.

When to Use

Activate this skill when:

Implementing file upload (single, multiple, drag-and-drop)
Building image galleries, carousels, or lightboxes
Creating video or audio players
Displaying PDF or document viewers
Optimizing media for performance (responsive images, lazy loading)
Handling large file uploads (chunked, resumable)
Integrating cloud storage (S3, Cloudinary)
Implementing media accessibility (alt text, captions, transcripts)
Designing empty states for missing media

Quick Decision Framework

Select implementation based on media type and requirements:

Images                  → Gallery pattern + lazy loading + responsive srcset
Videos                  → Player with controls + captions + adaptive streaming
Audio                   → Player with waveform + playlist support
Documents (PDF)         → Viewer with navigation + search + download
File Upload (<10MB)     → Basic drag-drop with preview
File Upload (>10MB)     → Chunked upload with progress + resume
Multiple Files          → Queue management + parallel uploads

For detailed selection criteria, reference references/implementation-guide.md.

File Upload Patterns

Basic Upload (<10MB)

For small files with simple requirements:

Drag-and-drop zone with visual feedback
Click to browse fallback
File type and size validation
Preview thumbnails for images
Progress indicator
Reference references/upload-patterns.md

Example: examples/basic-upload.tsx

Advanced Upload (>10MB)

For large files requiring reliability:

Chunked uploads (resume on failure)
Parallel uploads for multiple files
Upload queue management
Cancel and retry controls
Client-side compression

What ships with it

40 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
