The changes can cause package-supplied code and instructions to run during future agent actions and commits. - **Trigger:** npm installation in a detected Suppa application repository. - **Impact:** The package takes control of parts of a foreign project's agent workflow and repository hooks without an explicit setup command. - **Evidence paths:** package.json, skills/suppa-entity-code/scripts/postinstall.mjs, skills/suppa-entity-code/scripts/install-entity-code-guards.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-28T09:39:09.845Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall installs agent hooks, instruction files, Git hooks, CI configuration, and an npm script. - **Attack narrative:** The package's automatic postinstall finds the installer's working repository and, for projects it identifies as Suppa applications, runs an installer without requiring an explicit setup action. That installer adds Claude Code hooks for write and stop events, injects instructions into AGENTS.md and CLAUDE.md, creates a Git pre-commit hook and CI file, adds a package script, and may set Git's hooks path. These are broad mutations of a consumer project's AI-agent and development control surfaces. - **Rationale:** This is an unconsented postinstall mutation of a foreign project's AI-agent control surface and repository hooks. Guard conditions and an opt-out reduce scope but do not establish consent for the automatic broad changes. - **Files touched:** .claude/settings.json, AGENTS.md, CLAUDE.md, .githooks/pre-commit, .gitlab/suppa-schema-gate.yml, package.json, git config core.hooksPath ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The manifest automatically runs a postinstall script., Postinstall targets the consumer repository from INIT\_CWD and launches the guard installer without an explicit user command., The installer adds Claude Code hooks that run package code before and after write actions and when an agent stops., The installer writes AGENTS.md and CLAUDE.md, a Git hook, a CI file, and modifies the consumer package.json., It changes Git's core.hooksPath when none is configured, creating persistence in the consumer repository. - **Evidence against:** The postinstall script skips CI, global installs, unrelated projects, and supports an environment-variable opt-out., No runtime dependency on its own package name is declared., No postinstall network request or credential exfiltration was found; runtime network use is for the stated service. ## Public findings ### 1.
