Token cost

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.

Security

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 WebSearchTool for the tool web_search
  • You must have an entry in ToolFriendlyNameAndHandlers for 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.
