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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00031 | $0.00362 |
| Opus 5 | $0.00015 | $0.00181 |
| Sonnet 5 | $0.00006 | $0.00072 |
| Haiku 4.5 | $0.00003 | $0.00036 |
Grade A, and why
list-topics 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 9d 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.
What it actually says
List Topics in Solution
List all topics in the current agent with their trigger types and details.
Instructions
-
Auto-discover the agent directory — find all agents via:
Glob: **/agent.mcs.yml- If multiple agents found, list them and ask which one to inspect.
- NEVER hardcode an agent name or path.
-
Find all topic files in the discovered agent directory:
Glob: <discovered-agent>/topics/*.topic.mcs.yml -
For each topic file, read it and extract:
- Topic name (from the
# Name:comment or filename) - Trigger type (from
beginDialog.kind) - Trigger phrases (if
OnRecognizedIntent, fromtriggerQueries) - Number of actions in the
actionsarray - Dialog references (any
BeginDialogorReplaceDialogcalls)
- Topic name (from the
-
Present results in a table:
| # | Topic Name | Trigger | Phrases | Actions | Calls | |---|------------|---------|---------|---------|-------| | 1 | Greeting | OnRecognizedIntent | Hello, Hi, Hey | 2 | - | | 2 | Fallback | OnUnknownIntent | - | 4 | Escalate | -
Note any system topics (OnError, OnSelectIntent, OnSignIn) that should be modified with care.
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.

list-topics is a skill published in the GitHub repository microsoft/skills-for-copilot-studio (433 stars, last pushed 5d ago), licensed MIT. It adds 31 tokens to every session and 362 once invoked, about $0.0002 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.
