Skills for Copilot Studio is a plugin for authoring, testing, and troubleshooting standard Microsoft Copilot Studio agents as YAML files from a terminal or editor. It is intended for users of Claude Code, GitHub Copilot CLI, and VS Code who work with Copilot Studio agents. The catalogue add-ons are the plugin's skills, agents, hook, and plugin definition.
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.

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 | $0.00024 | $0.01450 |
| Opus 5 | $0.00012 | $0.00725 |
| Sonnet 5 | $0.00005 | $0.00290 |
| Haiku 4.5 | $0.00002 | $0.00145 |
Grade A, and why
clone-agent 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 7d 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 — 156 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Clone Agent
Guided flow to clone a Copilot Studio agent from the cloud to a local workspace. Walks the user through environment selection, agent selection, and downloads the agent's YAML files.
IMPORTANT: Do Not Modify Scripts
This is a new capability under active development. If the manage-agent script fails, do not attempt to fix, patch, or work around it. Instead:
- Show the user the full error output
- Direct them to https://github.com/microsoft/skills-for-copilot-studio/issues
- Suggest using the Copilot Studio VS Code extension directly as a fallback for push/pull/clone
Phase 0: Resolve Configuration
Look for existing connection details in this order. Stop at the first source that provides a tenantId:
0a. Scan for existing .mcs/conn.json files
Search the filesystem for previously cloned agents — these already have all the connection details:
Glob: **/.mcs/conn.json
Also search common project locations:
Glob: /Users/**/projects/**/.mcs/conn.json
Each conn.json contains TenantId, EnvironmentId, DataverseEndpoint, AgentManagementEndpoint, and AccountInfo. Parse any found files and collect unique tenant/environment pairs. If matches are found, present them to the user:
Found existing agent connections:
- Employee Assistant — Elad's Env (tenant: 8a235459...)
- IT Agent — Contoso Dev (tenant: efb073bb...)
Use one of these, or enter a different tenant ID?
If the user picks one → extract tenantId, environmentId, environmentUrl, agentMgmtUrl and skip to Phase 2 (or Phase 1 if they want a different environment).
0b. Check for a Copilot Studio URL
If the user pastes a Copilot Studio URL (e.g. from their browser while viewing the agent), extract environment and agent IDs directly — no need for list-envs or list-agents.
Recognised URL formats:
https://copilotstudio.microsoft.com/environments/<envId>/bots/<agentId>/overview
https://copilotstudio.preview.microsoft.com/environments/<envId>/bots/<agentId>
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.

clone-agent is a skill published in the GitHub repository microsoft/skills-for-copilot-studio (430 stars, last pushed 3d ago), licensed MIT. It adds 24 tokens to every session and 1,450 once invoked, about $0.0001 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 2026-08-30.
