copilot-framework@1.6.1
Contract-first Copilot scaffolding and workspace bootstrap scripts for Edenred repositories.
AI Security Review
scanned 6d ago · by lpm-firewall-aiThe package performs unconsented, install-triggered changes to the consumer repository's AI-agent configuration, including instructions and an MCP server registration. This is a concrete control-surface change and supports blocking publication.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source
Trigger
Installing the package in a repository root, unless CI is true or NODE_ENV is production.
Impact
Subsequent Copilot sessions can follow package-provided instructions and activate package-provided tooling from the consumer workspace.
Mechanism
The hook copies .github agent instruction files and creates or merges .vscode/mcp.json to register the package MCP server.
Policy narrative
On repository installs, the postinstall hook automatically copies the package's agent guidance and configures its MCP server in the consumer workspace. The hook has no user-consent check; its exemptions are development mode, CI, and production. This gives package-authored instructions and tooling a place in later Copilot sessions.
AI rationale
The package performs unconsented, install-triggered changes to the consumer repository's AI-agent configuration, including instructions and an MCP server registration. This is a concrete control-surface change and supports blocking publication.

Decision evidence
public snapshotAI identified this as a dangerous AI-agent capability at 94.0% confidence with low false-positive risk.
Evidence for policy risk
- package.json runs scripts/postinstall.js automatically after installation.
- The hook proceeds for repository roots; it skips only development mode, CI, and production, with no user consent check.
- During postinstall, it copies package-authored agent instructions and workspace guidance into the consumer repository.
- It creates or merges .vscode/mcp.json with a package MCP server, activating package-provided tooling in the consumer's Copilot workspace.
- The copied instructions establish default behavior for the consumer's Copilot sessions.
- The MCP configuration registers a copilot-context server that runs the package's dist/index.js with the workspace folder as its COPILOT_REPO.
Evidence against
- The hook skips when CI is true or NODE_ENV is production.
- Existing agent instruction files are preserved, and existing MCP server entries are merged.
