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.

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 | $0.00053 | $0.04861 |
| Opus 5.5 | $0.00021 | $0.01944 |
| Sonnet 5.5 | $0.00011 | $0.00972 |
| Haiku 4.5 | $0.00005 | $0.00486 |
Grade A, and why
kit-copilot-create-skill 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 1mo 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 — 353 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Create a New Agent Skill
What This Skill Does
Creates a properly structured Agent Skill directory containing a SKILL.md file and optional resources (scripts, templates, examples). Follows the Agent Skills specification and VS Code docs for Copilot's skills development.
An Agent Skill is a reusable capability — a multi-step procedure with optional bundled resources that the AI agent follows to complete a specific type of task. Skills are portable across VS Code, Copilot CLI, and Copilot coding agent.
Key Concepts: Skill vs Agent vs Prompt vs Instructions
Understanding the separation of concerns is critical for creating effective skills. Each customization mechanism has a distinct purpose:
| Component | Defines | Analogy | File Type |
|---|---|---|---|
| Agent Skill | Reusable CAPABILITY or multi-step workflow | A specialized training module the employee can use | SKILL.md in a skill directory |
| Custom Agent | WHO the AI is and HOW it behaves | The employee's role, personality, and work style | .agent.md |
| Prompt File | WHAT specific task to perform | A work order or task assignment | .prompt.md |
| Custom Instructions | WHERE — project context and standards | The company handbook | .instructions.md |
What ships with it
3 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.
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.

kit-copilot-create-skill is a skill published in the GitHub repository ikcode-dev/copilot-kit (29 stars, last pushed 7mo ago), licensed MIT. It adds 53 tokens to every session and 4,861 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-08-30.
