HTTP server wrapping the Claude Agent SDK. Persists chat events to Convex; the dashboard subscribes via Convex realtime

AI Security Review

scanned 8d ago · by lpm-firewall-ai

No confirmed malicious attack surface. The package is a user-invoked local HTTP bridge that runs Claude Agent SDK sessions, persists chat state to a configured Convex backend, and bundles a first-party reports plugin.

Static reason

No blocking static signals were detected.

Trigger

Explicit CLI/programmatic start: `baker-bridge hono` or createServer().start()

Impact

Expected agent bridge capabilities: project file access through the SDK, local session/memory files, attachment downloads, and chat relay posts.

Mechanism

local Hono bridge to Claude Agent SDK with env-configured Convex relay and package-owned plugin

Rationale

Source inspection shows a documented, explicit-run bridge with broad but package-aligned AI-agent/server behavior and no install-time mutation or covert exfiltration. Suspicious primitives such as fetch, env vars, child_process git/hook recovery, and .claude memory are tied to the advertised sandbox bridge workflow.

Decision evidence

public snapshot

AI called this Clean at 88.0% confidence as Benign with low false-positive risk.

Evidence for block

User-invoked server can run Claude Agent SDK with project settings and bundled local plugin via dist/hono/bridge-job.js and dist/hono/plugins.js.
Runtime writes local state/attachments under ~/.baker, /tmp/attachments, and project .claude/memory via dist/hono/runtime-files.js.
Runtime posts chat events/memory to env-controlled BAKER_CONVEX_SITE_URL and optional NotDiamond router URL.

Evidence against

package.json has no preinstall/install/postinstall lifecycle hooks.
dist/cli.js only starts the Hono server for explicit `baker-bridge hono`; no import-time execution beyond definitions.
Plugin files under plugins/reports are package-owned Claude plugin metadata/skill, not an install-time mutation of a foreign agent config.
Network endpoints are documented and env/user configured except optional NotDiamond model routing.
File reads/writes are bounded to the project sandbox, ~/.baker state, and /tmp attachments for documented bridge behavior.
No credential harvesting, stealth persistence, destructive payload, native binary loading, or remote code download found.
