They give the coding agent the context and rules needed to work consistently in the CDD repository and in projects created from its template.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: reads .claude/ paths; mentions subagents; mentions Claude Code.

This is drabaioli/cdd's own configuration. It tells Claude Code how to work on cdd itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything cdd configures →

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

cdd CLAUDE.md scanned grade A with 1 finding 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 6d 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.

CDD (Claude-Driven Development) — Claude Code Context

CDD is a human-in-the-loop workflow for evolving software projects together with Claude Code. This repository contains the process document (the philosophy and lifecycle) and the template (copy-paste material for bootstrapping new projects). The CDD repo itself uses CDD on itself; the template under template/ is content this project ships, not the project's own scaffolding.

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.
