spex@0.1.0

VERIFIED· install only

Publisher claims: "Spec-Driven Development (Spex) skill that manages the full SDLC — from requirement analysis and design to incremental implementation and submission. Invoked manually via /spex <command>. Supports commands: create (new), modify, apply (run, do, go), apply-one-step (step), merge (submit), archive, init." Observed in sandbox: no network, touches nothing outside the project, writes no memory.

Coverage

Nothing executable in the bundle ran; the trace covers the install step only.
Tested
every file read, file written and host contacted by what ran
Not tested

KillerSkills ran it in the KillerSkills honeypot sandbox (1 scenario; nothing executable in the bundle ran; the trace covers the install step only) on 2026-11-09 and scored it 87/100 (Verified). In what ran, nothing we could detect went wrong: no undeclared network egress, no credential reads, no persistent instruction writes. What it does with a real credential was not observed; the static findings and the publisher carry the rest of the score. Summary: no network, touches nothing outside the project, writes no memory.
