The Agent Skills Directory

[EXTERNAL_DOWNLOADS]: The skill downloads a pinned dependency @beeper/chat-adapter-matrix@0.2.0 from a standard registry (NPM) and instructs the agent to fetch the adapter implementation from the channels branch of the host project.
[COMMAND_EXECUTION]: Executes a Node.js one-liner to patch ESM extensions within the node_modules directory. This script performs a regex-based search-and-replace on dist/index.js to fix missing .js extensions in imports from matrix-js-sdk, which is a documented workaround for Node 22 compatibility.
[CREDENTIALS_UNSAFE]: The skill guides the user to set up Matrix credentials (MATRIX_PASSWORD, MATRIX_ACCESS_TOKEN). It follows best practices by using prompt secret for sensitive inputs and recommending environment variable storage (.env) rather than hardcoding. No actual secrets are included in the skill files; apply-fixtures.json contains only placeholder values for testing purposes.
[DYNAMIC_EXECUTION]: The patch script uses fs.writeFileSync to modify a dependency file at runtime. This is targeted to a specific file within the @beeper/chat-adapter-matrix package and does not incorporate untrusted external input into the execution logic.
