ECC is a toolkit that organizes and improves how coding agents work through skills, memory, security checks, research practices, and related extensions. It is for developers using agents such as Claude Code, Codex, OpenCode, and Cursor.
Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00010 | $0.00108 |
| Opus 5.5 | $0.00004 | $0.00043 |
| Sonnet 5.5 | $0.00002 | $0.00022 |
| Haiku 4.5 | $0.00001 | $0.00011 |
Grade A, and why
epic-validate scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
/epic-validate
Validate a single epic issue before publishing or review handoff.
node scripts/github-coordination.js validate <issue-number> --repo <owner/repo>
What this checks:
- Coordination state exists and is parseable.
- Validation state is satisfied by policy.
- Declared dependencies are closed.
- The epic is ready for the next workflow stage.
Compatibility aliases:
/quality-gate
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

epic-validate is a command published in the GitHub repository affaan-m/ECC (284,906 stars, last pushed today), licensed MIT. It adds 10 tokens to every session and 108 once invoked, about $0.0000 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.

amend-plan
Plan Amend - Discuss and apply amendments to a plan.json implementation plan.
rules
A command for managing coding rules stored in CLAUDE.md, AGENTS.md, and optional project RULES.md files. It can select built-in rules, add personal rules, change settings such as architecture or coverage, and control whether test-driven development (TDD) is required.
