ECC Tools Pro is live. The GitHub App now has Stripe billing with a Pro tier ($19/seat/month) for private repo analysis, 50 analyses/month, and AgentShield-backed scanning. Free tier remains at 10 analyses/month for public repos. Install at github.com/apps/ecc-tools, upgrade at ecc.tools/pricing.
Selective install is here. Install only what you need with --with and --without flags. ecc install --profile developer --with lang:typescript --with agent:security-reviewer --without skill:continuous-learning. Agent and skill component families are now in the install manifest.
12 language ecosystems. C#, Rust, Java, Kotlin, C++, Go, Python, TypeScript, Perl, PyTorch, Nuxt 4, and Flutter now have dedicated rules, agents, or skills.
v1.8.0 shifts ECC from "config bundle" to a practical agent harness performance system: more reliable hooks, stronger eval/quality controls, and tighter parity across Claude Code, Cursor, OpenCode, and Codex (macOS app + CLI).

Reliability and Hook Fixes
Fixed SessionStart root resolution (robust fallback when plugin root env is missing).
Fixed empty/partial session summary behavior by moving summary persistence to the Stop lifecycle path where transcript payload exists.
Added explicit hook controls:
ECC_HOOK_PROFILE=minimal|standard|strict
ECC_DISABLED_HOOKS=comma,separated,ids
Replaced fragile inline one-liner hook commands with dedicated scripts for safer cross-platform behavior.
Improved Windows path handling for doc-warning/whitelist logic.
Hardened observer behavior for non-interactive environments to reduce hang risk.
Cross-Harness Parity
Claude Code, Cursor, OpenCode, and Codex now share tighter behavior around hooks, commands, and skill execution semantics.
OpenCode command mirrors added for the new harness command set.
Codex config/docs alignment improved for both app and CLI workflows.
Compatibility Notes
autonomous-loops is retained for compatibility in this release.
continuous-agent-loop is now the canonical skill name.
Upgrade Path
Pull latest and reinstall/update ECC.
Run /harness-audit to baseline reliability and risk.
Use /quality-gate . --strict on active repos.
If needed, tune hooks with ECC_HOOK_PROFILE and ECC_DISABLED_HOOKS.

This release tightens ECC as a single source of truth across Claude Code, Codex, Cursor, and OpenCode, adds a full presentation-building workflow, and expands the repo with reusable content, research, and fundraising skills that are generic enough for any team to use.

Highlights
Direct Codex support — ECC now ships cleaner Codex app + CLI support with AGENTS.md-based setup, installer support, and Codex-facing docs
Cross-platform harness parity — Cursor, Codex, and OpenCode support were expanded so the same repo structure works cleanly across all major AI coding tools
New frontend-slides skill — Build animation-rich, zero-dependency HTML slide decks and convert PPTX workflows into web-native presentations with strict viewport-fit rules
5 new generic business/content skills — article-writing, content-engine, market-research, investor-materials, and investor-outreach
Cowork marketplace compatibility — Plugin manifests were reworked for Cowork compatibility and cleaner marketplace behavior
Chief-of-staff agent — Added a communication-triage oriented agent for coordination-heavy workflows

Platform and Workflow Improvements
Improved Codex packaging and discovery
Better OpenCode package/release alignment
Cross-platform hook and path fixes
Auto-detect formatter support in the post-edit hook
Cleaner rule priority and development workflow documentation
Better skill metadata traceability and distribution support
Why This Matters
ECC is no longer just “a Claude Code plugin.” It now works as a multi-harness operating layer for modern AI coding environments while keeping the repo coherent enough to ship from one place.
