Visual Studio Code is a code editor that supports editing, navigating, understanding, debugging, and extending software projects. Developers use it for the edit-build-debug cycle, and the catalogue add-ons provide skills, instructions, and agents for working within the editor.
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 | $0.00024 | $0.00306 |
| Opus 5 | $0.00012 | $0.00153 |
| Sonnet 5 | $0.00005 | $0.00061 |
| Haiku 4.5 | $0.00002 | $0.00031 |
Grade A, and why
updateCopilotCLIToolMapping 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 today.
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
The constant ToolFriendlyNameAndHandlers in src/extension/chatSessions/copilotcli/common/copilotCLITools.ts
contains a mapping of known tools, and how the progress and output is displayed.
The type ToolInfo contains all of the tools and their corresponding arguments/return types.
All of this information has been derived from /src/tools/**
I would like you to update the ToolFriendlyNameAndHandlers mapping as well as ToolInfo and other related types based on any new/updated tools that are defined in the CLI runtime repo.
- You must create simple TypeScript interfaces as done today see
WebSearchToolfor the toolweb_search - You must have an entry in
ToolFriendlyNameAndHandlersfor the new tools - You must add/update any of the related tests
At the end of all of your changes you must provide a summary
- List of updated tools and their friendly names What are the updates to, did the arguments change, did the return type change, etc. How does this impact what is displayed to the user
- List of new tools and their friendly names How are the arguments and output displayed to the user
Finally, if the user hasn't already provided this, then you must ask for the folder path to the CLI runtime repo.
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.

updateCopilotCLIToolMapping is a command published in the GitHub repository microsoft/vscode (190,932 stars, last pushed today), licensed MIT. It adds 24 tokens to every session and 306 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 2026-09-06.
