The package mutates AI-agent and MCP control surfaces during npm install. Even though this matches the package theme, the postinstall hook writes agent instructions and MCP configuration into the installing repository without an explicit CLI action. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 90.0% - **Started:** 2026-07-01T01:41:21.364Z - **Finished:** 2026-07-01T01:42:31.063Z - **Download time:** 510 ms - **Static scan time:** 202 ms - **AI review time:** 68986 ms - **Total time:** 69699 ms ## Security analysis ### Published attack-surface review - **Summary:** The package mutates AI-agent and MCP control surfaces during npm install. Even though this matches the package theme, the postinstall hook writes agent instructions and MCP configuration into the installing repository without an explicit CLI action. - **Trigger:** npm install of copilot-framework in a repository-like directory - **Impact:** Installer can change future Copilot/agent behavior and register a local MCP server for the workspace. - **Evidence paths:** package.json, scripts/postinstall.js, workspace/.github/AGENTS.md, workspace/.github/copilot-instructions.md, workspace/.vscode/mcp.json - **Review source:** ai\_review - **Reviewed:** 2026-07-01T01:42:31.063Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall scaffolds .github agent instructions and .vscode MCP config - **Attack narrative:** On install, scripts/postinstall.js detects a repository root and writes package-supplied .github agent guidance plus .vscode/mcp.json into the target project, then hides those generated paths in .gitignore. This creates an unconsented lifecycle mutation of AI-agent/MCP control files, even though no exfiltration endpoint or destructive payload was found. - **Rationale:** Source inspection confirms install-time writes to AI-agent instructions and MCP config, which is a concrete unconsented control-surface mutation. No network theft was found, but the lifecycle behavior itself is blocking under the firewall policy. Product guard normalized a non-low false-positive publish\_block request to warn-only suspicious. - **Files touched:** .github/AGENTS.md, .github/copilot-instructions.md, .github/skills/, .vscode/mcp.json, context/, .gitignore ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for:** package.json defines postinstall: node scripts/postinstall.js, scripts/postinstall.js runs on npm install outside CI/production when TARGET\_ROOT looks like a repo, scripts/postinstall.js copies workspace/.github/AGENTS.md and copilot-instructions.md into target .github, scripts/postinstall.js creates or merges .vscode/mcp.json pointing to package dist/index.js, scripts/postinstall.js adds target .github, context, and .vscode/mcp.json paths to .gitignore - **Evidence against:** No credential harvesting or network exfiltration found by source grep, workspace/.vscode/mcp.json uses local node command only, CLI shell execution is user-invoked or env-controlled via COPILOT\_CODEGRAPH\_REINDEX\_CMD, Templates appear workflow-oriented, not secret-stealing or destructive ## Public findings ### 1.
