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.

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 | $0.00036 | $0.01261 |
| Opus 5.5 | $0.00014 | $0.00504 |
| Sonnet 5.5 | $0.00007 | $0.00252 |
| Haiku 4.5 | $0.00004 | $0.00126 |
Grade A, and why
musubix-code-generation 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.

MUSUBIX Code Generation Skill
This skill guides you through generating code from design specifications following MUSUBIX methodology.
Prerequisites
Before generating code:
- Verify design document exists (
DES-*) - Verify requirements are traceable (
REQ-*) - Check

Code Generation Workflow
Step 1: Read Design Document
# Generate code from design
npx musubix codegen generate <design-file>
Step 2: Generate with Traceability
Always include requirement references:
/**
* UserService - Handles user operations
*
* @see REQ-INT-001 - Neuro-Symbolic Integration
* @see DES-INT-001 - Integration Layer Design
*/
export class UserService {
// Implementation
}
Step 3: Follow Test-First (Article III)
- Write test first:
describe('UserService', () => {
it('should create user', async () => {
const service = new UserService();
const user = await service.create({ name: 'Test' });
expect(user.id).toBeDefined();
});
});
- Implement minimal code:
export class UserService {
async create(data: CreateUserDto): Promise<User> {
return { id: generateId(), ...data };
}
}
- Refactor
Design Pattern Templates
Singleton Pattern
/**
* @see REQ-DES-001 - Pattern Detection
* @pattern Singleton
*/
export class ConfigManager {
private static instance: ConfigManager;
private constructor() {}
static getInstance(): ConfigManager {
if (!ConfigManager.instance) {
ConfigManager.instance = new ConfigManager();
}
return ConfigManager.instance;
}
}
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.

musubix-code-generation is a skill published in the GitHub repository nahisaho/katashiro (0 stars, last pushed 9mo ago), licensed MIT. It adds 36 tokens to every session and 1,261 once invoked, about $0.0001 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 2026-08-31.
