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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00015 | $0.00116 |
| Opus 5 | $0.00008 | $0.00058 |
| Sonnet 5 | $0.00003 | $0.00023 |
| Haiku 4.5 | $0.00002 | $0.00012 |
Grade A, and why
epic-sync 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 3d 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-sync
Run a deterministic sync for epic issues.
node scripts/github-coordination.js sync --repo <owner/repo>
What this does:
- Reads issue bodies as the canonical epic state.
- Reconciles the coordination block with labels.
- Writes a fresh local snapshot for each epic issue.
- Keeps the SQLite cache aligned with GitHub.
Compatibility aliases:
/projects/work-items sync-github
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-sync is a command published in the GitHub repository affaan-m/ECC (250,130 stars, last pushed yesterday), licensed MIT. It adds 15 tokens to every session and 116 once invoked, about $0.0001 per session on Opus 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.
Other commands, from other repositories
update-documentation
You are a release engineer responsible for maintaining the root-level CHANGELOG.md and verifying plugin READMEs. Analyze git changes, update the single CHANGELOG.md following the Keep a Changelog format organized by plugin, and ensure plugin READMEs accurately reflect their contents.
dev
You are an experienced Tech Lead overseeing multiple AI Worker Agents on software projects. The user is the PM / product owner. You drive all technical execution and communicate in natural language.
gh_close
Close one or more GitHub issues by number with GitHub's native close reasons — completed (default), not planned (--not-planned / --wontfix), or duplicate (--duplicate ) — or reopen with --reopen. Echoes each issue's title before acting and pauses when other open issues depend on the one being closed. Use for "ghclose".
t00-git
A Git assistant that explains version-control commands and guides work with commits, branches, merges, pull requests, and conflicts. Git records code changes so developers can review, restore, and share versions.
t00-new-pj
A command for starting a new T00 project by asking planning questions, assigning a project number, creating a folder and project file, and updating the project index. T00 appears to be a local project-management setup.
t00-estimate
A command that estimates whether a requested software task is practical before implementation and reports what was completed afterward. It uses different report formats depending on whether the user asks to start work or review the result.
