## Verdict summary
**Flagged as AI-agent capability risk** — Allowed by default with warning: agent-facing configuration or capability changes need review before use.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Warn-only AI-agent capability risk
- **Public report status:** Published
- **Threat category:** AI-agent capability abuse
- **Selected version:** 0.1.1936
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

Review flagged AI-agent configuration or capability changes. This remains warn-only unless evidence shows foreign-agent hijack through preinstall/install/postinstall, hidden persistence, exfiltration, remote code execution, or other concrete malicious behavior.

## Security analysis

### Published attack-surface review

- **Summary:** Explicit \`tsci init\` can download and install TSCircuit AI skills into project-local Claude and Codex-style skill directories. No install-time execution or unconsented broad agent-control mutation was found.

- **Trigger:** User runs \`tsci init\` (or supplies \`--yes\`).

- **Impact:** Adds remotely fetched skill files that can influence compatible AI agents in that project.

- **Evidence paths:** package.json, cli/entrypoint.js, dist/cli/main.js, dist/cli/build/build.worker.js, dist/cli/snapshot/snapshot.worker.js

- **Review source:** ai\_review

- **Reviewed:** 2026-08-14T21:56:36.971Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** Project-scoped remote AI-skill provisioning

- **Rationale:** The package has no install lifecycle hook, but its explicit initialization command provisions remote AI-agent skills into recognized project directories. Policy classifies this as a warn-level agent capability risk, not a publish-block chain.

- **Files touched:** .claude/skills/tscircuit, .agents/skills/tscircuit

- **Network endpoints:** https://api.github.com/repos/tscircuit/skill/contents

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 91.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Dangerous Capability

- **False-positive risk:** Low

- **Evidence for:** \`tsci init\` provisions skills under \`.claude\` and \`.agents\`., It fetches repository content and writes it into those skill directories., The behavior is reached by the explicit \`init\` command and prompts unless \`--yes\` is used.

- **Evidence against:** No npm preinstall, install, or postinstall lifecycle hook is declared., The CLI entrypoint only selects a local runner and launches its bundled main CLI., Agent-skill setup is project-scoped and same-vendor, not a broad foreign control-surface mutation.
