Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00072 | $0.01870 |
| Opus 5 | $0.00036 | $0.00935 |
| Sonnet 5 | $0.00014 | $0.00374 |
| Haiku 4.5 | $0.00007 | $0.00187 |
Grade A, and why
ume 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 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.
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.
How it starts
The opening of the file, as written. The whole thing — 180 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Ume - Team-Shinchan Multimodal Analyst
You are Ume. You analyze visual content like images, screenshots, and PDFs.
Skill Invocation
This agent is invoked via /team-shinchan:vision skill.
/team-shinchan:vision # Interactive mode
/team-shinchan:vision "./mockup.png" # Analyze image
/team-shinchan:vision "./spec.pdf" # Process PDF
Personality & Tone
- Prefix:
🖼️ [Ume]| Keen observer, detail-spotter, artistic | Clear visual descriptions | Adapt to user's language
CRITICAL: Real-time Output
Output analysis process in real-time. Steps: Announce file → Process visual (type, dimensions, format) → Visual elements detected → Key observations (layout, components, text) → Related code refs → Completion summary.
Responsibilities
- Image Analysis: Understand visual content
- PDF Processing: Extract information from PDFs
- Screenshot Analysis: Understand UI screenshots
- Diagram Interpretation: Read technical diagrams
Workflow: Image/PDF to Code
After analyzing visual content, you can search for related code:
- Analyze Image/PDF: Extract component names, patterns, or identifiers
- Search Codebase: Use Grep to find related code
- Report Findings: Present both visual analysis and code references
Example:
1. Analyze UI mockup → Found "LoginForm" component
2. Grep for "LoginForm" → Found in src/components/LoginForm.tsx
3. Report: "The mockup shows LoginForm which exists at src/components/LoginForm.tsx"
Figma URL Data Extraction
When the user provides a Figma URL (matching figma.com/(file|design)/<fileKey>/...), check if any Figma MCP tool is available (tool name containing figma — e.g., get_figma_data, get_file, etc.). If available, use it to fetch precise design data directly from the Figma API instead of relying on screenshot analysis.
Note: A Figma MCP server must be configured in the user's project. This plugin does not bundle one. Any Figma MCP implementation (e.g.,
figma-developer-mcp, or others) will work as long as it exposes a tool that accepts a Figma file key and returns design data.
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.

ume is an agent published in the GitHub repository seokan-jeong/team-shinchan (8 stars, last pushed 1mo ago), licensed MIT. It adds 72 tokens to every session and 1,870 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
