Spec Converge

Category: Security · Sub-category: security-misc · Last updated: 2026-05-21

Iteratively review an instar-development spec with multi-angle internal reviewers (security, scalability, adversarial, integration) and cross-model external reviewers (GPT, Gemini, Grok) until convergence, then produce a comprehensive ELI10 convergence report. Output is a spec tagged review-convergence — one of the two tags /instar-dev requires before it will touch instar source. NOT user-invocable; run by the instar-developing agent before any spec-driven /instar-dev work.

Audience: the instar-developing agent. End users do not invoke this. Throughout this document, "the agent" refers to the instar-developing agent running the skill.
