Nova

Self-only metrics (n < threshold = gray-out, honest signal — see docs/guides/measurement.md) · UI changes gated by G1+G3 pair — see docs/guides/ui-quality-gate.md:

Verify before you ship. Every time. AI-generated code, cross-checked by an independent adversarial evaluator — before commit, before deploy.

A Claude Code plugin. 17 slash commands, 12 skills, 6 specialist agents, local MCP server.

AI coding tools make you type faster — but the real bottleneck isn't typing. A single wrong decision in week 1 compounds into a full rewrite by week 4. Nova gives AI agents the operating environment they need to work reliably.

Nova is a Claude Code plugin that makes AI agents operate dependably in real projects. It started as a Quality Gate — and that's still the strongest pillar — but it now spans five:

Pillar	Purpose
Environment	Worktree, secret-sharing, isolated agent workspaces — see Worktree Setup guide
Context	Session-to-session state continuity (NOVA-STATE.md)
Quality	Generator-Evaluator separation, file-bound pre-commit hard gate — run gate-only alongside other plugins via NOVA_COEXIST
Collaboration	Design→build→verify orchestration, multi-AI consulting
Evolution	Self-diagnosis and auto-upgrade

The Quality pillar remains load-bearing: independent evaluation, multi-AI cross-verification, and design-implementation gap detection are injected into every session automatically.

What's New in v5.23.0 — ECC Adversarial Gap Closure

A multi-release sprint that adopted measured ideas from the ECC (Everything Claude Code) ecosystem while preserving Nova's cohesive identity. Identity is discovered after the mechanism proves itself, not declared upfront — the additions below were absorbed because they passed adversarial evaluation, not because of vocabulary fit.

Release	Addition	Source
v5.23.0	/nova:audit-self --jury — Red(attacker) / Blue(defender) / Auditor(arbiter) 3-persona adversarial security audit. Counters single-evaluator self-justification bias.	ECC AgentShield §P2-3
v5.22.3	release.sh Step 2.5 hygiene gates — fail-open advisories for review trail / NOVA-STATE.md freshness / audit-self regression integration	Self-gap (Always-On 4 enforcement)
v5.22.2	audit-self rule sensitivity layer (T11–T25) — 15 inline violation fixtures prove rules catch intended patterns. Self-discovered jq escape bug in T13.	Self-discovered via meta-loop
v5.22.1	hooks/session-start.sh MCP load alert — caches claude mcp list 1h, surfaces ⚠️ when >10 servers active	ECC §P1-2 (10/80 rule)
v5.22.0	/nova:audit-self command + 30-rule security rulebook (5 categories: plugin/hooks/agents/skills/commands). Generator-Evaluator separation applied to Nova's own codebase.	ECC AgentShield §P1-1

Closed: Known Risks Medium (release.sh review-trail gate) and Info (audit-self rule sensitivity). Identity layer untouched — five pillars, slogan, Generator-Evaluator separation, NOVA-STATE 9-entry continuity all intact. See docs/proposals/2026-04-29-ecc-adversarial-gap.md for the full adoption rationale and what was deliberately rejected (183-skill quantity race, auto-promotion, 100% PreToolUse observation).
