The package implements production static cache generation and reads that cache through a same-origin relative path. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Clean - **Confidence:** 99.0% - **Started:** 2026-08-18T15:21:08.294Z - **Finished:** 2026-08-18T15:21:38.587Z - **Download time:** 754 ms - **Static scan time:** 22 ms - **AI review time:** 29516 ms - **Total time:** 30293 ms ## Security analysis ### Published attack-surface review - **Summary:** No confirmed malicious attack surface. The package implements production static cache generation and reads that cache through a same-origin relative path. - **Trigger:** Application runtime invokes the exported middleware in production with TSS\_CLIENT\_OUTPUT\_DIR configured. - **Impact:** Writes cache JSON to the configured application output directory; no external exfiltration or install-time action observed. - **Evidence paths:** package.json, src/index.ts, src/staticFunctionMiddleware.ts, dist/esm/staticFunctionMiddleware.js - **Review source:** ai\_review - **Reviewed:** 2026-08-18T15:21:38.587Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Static server-function cache serialization and retrieval. - **Rationale:** Source inspection shows a static-cache middleware, not malicious behavior. The flagged filesystem, environment, and fetch primitives are constrained to the configured build output and a relative cache URL. - **Files touched:** src/staticFunctionMiddleware.ts, package.json, src/index.ts, dist/esm/staticFunctionMiddleware.js ### Review decision - **Verdict:** Clean - **Confidence:** 99.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence against:** package.json has no preinstall, install, or postinstall hook., Only exported entry re-exports staticFunctionMiddleware., Runtime writes serialized server-function cache data only beneath TSS\_CLIENT\_OUTPUT\_DIR., Client fetch uses a relative /\_\_tsr/staticServerFnCache/ URL, not an external endpoint., No child process, eval, dynamic loading, credential harvesting, or agent-control writes found. ## Public findings ### 1.
