Intelligent Terminal is an experimental fork of Windows Terminal that adds native support for AI agents through the Agent Client Protocol. It is for Windows users who want to manage compatible agent command-line tools alongside terminal tabs, profiles, themes, shells, and keyboard shortcuts, and the catalogue entries provide instructions, skills, hooks, and a plugin for working with it.

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 | $0.03888 | $0.03888 |
| Opus 5.5 | $0.01555 | $0.01555 |
| Sonnet 5.5 | $0.00778 | $0.00778 |
| Haiku 4.5 | $0.00389 | $0.00389 |
Grade A, and why
intelligent-terminal agent-skills.instructions.md 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.

Agent Skills File Guidelines
Instructions for creating effective and portable Agent Skills that enhance GitHub Copilot with specialized capabilities, workflows, and bundled resources.
What Are Agent Skills?
Agent Skills are self-contained folders with instructions and bundled resources that teach AI agents specialized capabilities. Unlike custom instructions (which define coding standards), skills enable task-specific workflows that can include scripts, examples, templates, and reference data.
Key characteristics:
- Portable: Works across VS Code, Copilot CLI, and Copilot coding agent
- Progressive loading: Only loaded when relevant to the user's request
- Resource-bundled: Can include scripts, templates, examples alongside instructions
- On-demand: Activated automatically based on prompt relevance
Directory Structure
Skills are stored in specific locations:
| Location | Scope | Recommendation |
|---|---|---|
.github/skills/<skill-name>/ |
Project/repository | Recommended for project skills |
.claude/skills/<skill-name>/ |
Project/repository | Legacy, for backward compatibility |
~/.github/skills/<skill-name>/ |
Personal (user-wide) | Recommended for personal skills |
~/.claude/skills/<skill-name>/ |
Personal (user-wide) | Legacy, for backward compatibility |
Each skill must have its own subdirectory containing at minimum a SKILL.md file.

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.

intelligent-terminal agent-skills.instructions.md is an instructions file published in the GitHub repository microsoft/intelligent-terminal (2,056 stars, last pushed today), licensed MIT. It adds 3,888 tokens to every session, about $0.0156 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.
