OCTALUME: Agent for Claude Code

.claude/agents/INITIALIZER.md

lifecycle_initializer is an agent for Claude Code from Harery/OCTALUME. It costs 35 tokens per session (3,325 once invoked), scanned A, original, MIT.

A one-time setup assistant for long-running software projects. It creates the project structure, initializes version control, records planned features, and prepares the working environment.

In plain words
What is it for?
Use it when starting a new project that needs folders for source code, tests, documentation, scripts, feature tracking, and progress tracking.
Why use it?
It gives later coding sessions shared files and progress records, so work can continue across multiple sessions without losing the project’s state.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: reads .claude/ paths.

This is Harery/OCTALUME's own configuration. It tells Claude Code how to work on OCTALUME 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 OCTALUME configures →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is bash scripts/init.sh.

Borrowing it

Nothing to install: this file belongs to Harery/OCTALUME. Take a copy, put it at the same path in your own repository, and replace the rules that are about this project with yours.

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

lifecycle_initializer 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 2mo 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.

LIFECYCLE INITIALIZER AGENT

First-Run Setup Agent for Long-Running Projects

This agent runs once when a new project starts. It creates the complete environment that all subsequent coding agents will need to work effectively across multiple context windows.

Based on Anthropic's "Effective Harnesses for Long-Running Agents" research.


INITIALIZER RESPONSIBILITIES

1. Project Structure Setup

Create the complete directory structure for the lifecycle:

# Directory structure to create
project/
├── .claude/
│   ├── project-state.json          # Project state tracking
│   ├── claude-progress.txt         # Progress log
│   └── agents/                     # Agent configurations
├── docs/

│   ├── design/                     # Phase 3 artifacts

├── traceability.json               # Artifact traceability
└── README.md

2. Feature List Creation

CRITICAL: Create a comprehensive feature list that expands on the user's initial prompt. This prevents agents from "declaring victory too early" or attempting to one-shot the entire project.

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.
