In plain words
What is it for?
Use it when setting up favicons for Rails, Next.js, Gatsby, SvelteKit, Astro, or other web projects.
Why use it?
It removes the repetitive work of creating the different icon files and wiring them into a project correctly.

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.

Security

Grade A, and why

github 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 yesterday.

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.

The opening of the file, as written. The whole thing — 105 lines — stays where its author put it; the contents beside it link to each section on GitHub.

GitHub Issues Manager

Complete GitHub issue management using the gh CLI tool. This Skill provides comprehensive capabilities for creating, viewing, updating, and managing GitHub issues.

Capabilities

  1. Create issues - Create new GitHub issues with context from conversations
  2. List issues - View and filter issues by state, labels, assignees
  3. View issues - Display full issue details including comments
  4. Update issues - Modify titles, bodies, labels, and assignees
  5. Close issues - Close issues with optional closing comments
  6. Assign issues - Assign issues to team members

Quick Reference

For detailed instructions on each operation, see:

Common Workflows

Bug reporting workflow

  1. User reports a bug in conversation
  2. Create issue with /create-issue or ask me to create one
  3. Issue is created with context from our discussion
  4. Assign to appropriate team member
  5. Add labels (bug, priority, etc.)

Issue triage workflow

  1. List open issues with filters
  2. View specific issues for details
  3. Update labels and assignments
  4. Close resolved issues with status updates

Sprint planning workflow

  1. List issues by label or milestone
  2. Assign issues to team members
  3. Update priorities and estimates
  4. Track progress through status updates

Critical Instructions

REQUIRED: Before executing ANY GitHub issue operations, you MUST load the relevant reference file(s) using the Read tool. These references contain essential command patterns, parameters, and workflows that are NOT included in this overview.

When the user asks to work with GitHub issues:

  1. Identify the operation they want to perform (create, list, view, update, close, assign)
  2. MANDATORY: Load the relevant reference file(s) using the Read tool BEFORE executing any commands:
    • Creating issues → Read CREATE_ISSUE.md FIRST
    • Listing issues → Read LIST_ISSUES.md FIRST
    • Viewing issues → Read VIEW_ISSUE.md FIRST
    • Updating issues → Read UPDATE_ISSUE.md FIRST
    • Closing issues → Read CLOSE_ISSUE.md FIRST
    • Assigning issues → Read ASSIGN_ISSUE.md FIRST
  3. Execute the gh CLI commands following the exact patterns from the loaded reference
  4. Use temporary files for issue bodies to avoid markdown conflicts (as specified in references)
  5. Confirm actions and display results

Files

What ships with it

6 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.
