Done means the shim-cli submission is represented consistently and its stated compatibility details are preserved.

Plugin name

shim-cli

Short description

Finds secrets and personal data locally, in your prompts and in the tool results the agent reads, and tells you what it found. In VS Code it reports, and with enforcement on it stops a prompt or denies a tool call before it runs; a result that has already reached the model is reported, never masked. No account, no network destination, no telemetry.

Additional notes for reviewers

I'm one of the maintainers. What each client was measured to grant is in docs/compatibility.md at this commit; the short version:

• VS Code (measured on 1.137.0 with Copilot Chat 0.65.0) is the client this listing serves. shim reports what it finds in prompts and tool results. With enforcement turned on in its config it can stop a prompt at UserPromptSubmit or deny a tool call at PreToolUse. It never masks in VS Code. After a tool has run it can only report: a PostToolUse block was measured and the model still read the result.
• In VS Code a read_file result reaches the hook as an empty tool_response, so file reads are checked by path only. run_in_terminal output arrives in full.
• GitHub Copilot CLI loads the same com.github.copilot/hooks/hooks.json, but the command exits at once when COPILOT_CLI is set, so installing this plugin in Copilot CLI inspects nothing. Copilot CLI users get the hook from the PyPI package with shim install copilot. The Copilot app has not been tested.
• If no Python 3.9+ is found or the hook fails, the prompt or tool call goes through uninspected. Detection is regex plus checksums, so expect false positives and misses.
• macOS and Linux are the supported platforms; the hook commands run through sh.

v1.0.1 is an annotated tag (tag object c83249766a307c78a5a2e2533b95fa9598ceb371); the SHA above is the commit it points to.
