Env Reporter

A safe helper. It reads environment values and builds local data structures, but never sends anything over the network — so there is no source→sink flow for the taint pass to flag.

Step 1 — Run

python3 ~/.claude/skills/env-reporter/scripts/client.py

Why this passes audit (negative test for the taint pass)

scripts/client.py exercises every guard that keeps the taint pass quiet:

  • A credential read that never reaches a network call (os.environ["HOME"] then print) — sink-reachability guard: a secret that goes nowhere is not a flow.
  • A credential passed only to a same-file, non-network helper — the pass is intraprocedural and the helper is not a sink, so nothing fires.
  • Non-credential values built and used locally — no source, no sink.

There is no requests / httpx / urllib call anywhere, so neither HI009 nor any TF rule fires.

Expected verdict: 🟢 GREEN, exit 0.
