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
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00006 | $0.00279 |
| Opus 5 | $0.00003 | $0.00139 |
| Sonnet 5 | $0.00001 | $0.00056 |
| Haiku 4.5 | $0.00001 | $0.00028 |
Grade A, and why
plan 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 yesterday.
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
Plan Command
Create a detailed implementation plan for: $ARGUMENTS
Your Task
- Restate Requirements - Clarify what needs to be built
- Identify Risks - Surface potential issues, blockers, and dependencies
- Create Step Plan - Break down implementation into phases
- Wait for Confirmation - MUST receive user approval before proceeding
Output Format
Requirements Restatement
[Clear, concise restatement of what will be built]
Implementation Phases
[Phase 1: Description]
- Step 1.1
- Step 1.2 ...
[Phase 2: Description]
- Step 2.1
- Step 2.2 ...
Dependencies
[List external dependencies, APIs, services needed]
Risks
- HIGH: [Critical risks that could block implementation]
- MEDIUM: [Moderate risks to address]
- LOW: [Minor concerns]
Estimated Complexity
[HIGH/MEDIUM/LOW with time estimates]
WAITING FOR CONFIRMATION: Proceed with this plan? (yes/no/modify)
CRITICAL: Do NOT write any code until the user explicitly confirms with "yes", "proceed", or similar affirmative response.
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.

plan is a command published in the GitHub repository affaan-m/ECC (246,988 stars, last pushed yesterday), licensed MIT. It adds 6 tokens to every session and 279 once invoked, about $0.0000 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.
