Overview
ECC Tools is an open agent harness platform created by developer Affaan Mustafa, originating at a 2026 Claude Code hackathon hosted by Cerebral Valley and Anthropic, that analyzes a repository and generates project-specific skills, rules, hooks, and security checks for AI coding agents.
It is built on top of a large open-source library of pre-built skills, agents, and commands, and adds a hosted GitHub App plus a dedicated security scanner called AgentShield for auditing AI agent configurations.
Key Features
The platform generates reusable skills, rules, and commands based on a repository's commit history and existing configuration, and proposes them as reviewable pull requests rather than silent automated changes.
AgentShield runs roughly 100 static analysis rules against agent configs, MCP servers, and tool permissions, with an optional multi-model red-team/blue-team/auditor pipeline to simulate adversarial attacks against an agent's guardrails.
Pricing
ECC Tools offers a Free tier for public repositories with 10 analyses per month, a Pro tier at $19 per seat per month (or $190 per seat yearly) for private repos and deeper audits, and a custom-priced Enterprise tier for organization-wide governance and rollout.
All tiers build on the free, MIT-licensed open-source repository, so teams can adopt the core skills library at no cost before upgrading for private-repo automation and security scanning.
Key Features
Repository-aware skill generation — Analyzes commit history and existing configuration to generate project-specific skills, rules, and commands for AI coding agents.
Reviewable pull-request automation — Proposes generated configuration as pull requests for human review rather than modifying a repository silently.
Issue-comment commands — Supports commands like analyze, setup, and audit triggered directly from GitHub issue comments.
AgentShield security scanning — Runs roughly 100 static analysis rules against agent configs, MCP servers, and tool permissions to catch misconfigurations.
Multi-model adversarial testing — An optional red-team, blue-team, and auditor pipeline simulates attacks against an agent's guardrails using multiple AI models.
Cross-harness compatibility — Works across Claude Code, Codex, Cursor, and OpenCode rather than locking teams into a single agent vendor.
Open-source skills library — Provides a free, MIT-licensed library of hundreds of pre-built skills, agents, and commands covering planning, testing, and code review.
Enterprise governance — Enterprise tier adds SSO-ready governance, audit logs, and custom policy packs for organization-wide rollout.
Pros & Cons
Pros
Free tier and open-source core make it accessible before committing to a paid plan
Combines context generation and security scanning for AI agents in one workflow
Works across multiple AI coding agent platforms instead of a single vendor
Pull-request-based automation keeps a human in the review loop
Cons
Very new project (2026 origin), with a shorter track record than established dev tools
Private repository features require a paid Pro or Enterprise plan
Enterprise pricing is not published and requires direct sales contact
Effectiveness depends on the quality of a repository's existing commit history and documentation
