Iteratively review an instar-development spec with multi-angle internal reviewers (security, scalability, adversarial, integration, decision-completeness, lessons-aware) and real cross-model external reviewers routed through the agent's own installed CLIs (codex → GPT-tier, gemini → Gemini-tier; one pass per available family) 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…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# /spec-converge **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. --- ## What this skill does Takes a spec file, runs multiple parallel reviewers against it, updates the spec to address their findings, runs another round, and repeats until convergence. Produces a final converged spec and a comprehensive human-readable report. The purpose is to catch architectural, security, adversarial, scalability, and integration issues BEFORE code is written, not after. The single-reviewer pattern used by `/instar-dev`'s existing second-pass step has proven too narrow in practice — a four-reviewer parallel audit on the integrated-being ledger PR surfaced 14 serious issues that a single reviewer had missed. This skill bakes that multi-angle pattern in as the structural default for any substantive instar-dev work. ## When it runs Before `/instar-dev` touches any instar source, the change's spec must pass through this skill. `/instar-dev`'s pre-commit hook refuses work unless: …

How to install
mdr add jkheadley/instar/spec-converge@sha256:09aaf442a2c87fa6The line at the top of this page pins the label git:20261022.976268d, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
