What is Instability CLAUDE.md?

Repository instructions for Instability, a Python chatbot and security-testing toolkit. They describe how to run its chatbot, diagnostics, tools, tests, and v3 environment checks.

Use them when developing or reviewing Instability, running its chatbot or diagnostic tools, checking the v3 environment, or running tests.

They give a coding agent the project’s expected commands, structure, and simple function-based style, reducing the chance of changes that conflict with the repository.

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.

Model	Per session	Once invoked
Fable 5.1	$0.01883	$0.01883
Opus 5.5	$0.00753	$0.00753
Sonnet 5.5	$0.00377	$0.00377
Haiku 4.5	$0.00188	$0.00188

Security

Grade A, and why

Instability CLAUDE.md 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.

Run test suite: python instability.py run-tests

Code Style Guidelines & Design Philosophy

Simplicity First: Avoid framework complexity and OOP abstraction - keep code easy to understand, maintain, and customize
Function-Based: Use simple functions rather than complex class hierarchies
No Heavy Frameworks: Avoid LangChain, complex ORMs, or other heavyweight abstractions
Direct Implementation: Prefer direct library usage over abstraction layers
No Emojis: Never use decorative emojis in code, terminal output, or documentation. This is a professional pentesting tool that needs clean, scannable output during critical network diagnostics.
Functional Symbols: Use plain Unicode symbols for functional indicators:
- ☐ for unchecked/incomplete items
- ☑︎ for checked/complete items
- ⚠ for warnings (plain symbol only)
- Use text like [OK], [FAIL], [PASS], [ERROR] for status indicators
Imports: Standard library imports first, then third-party, then local modules
Typing: Use Python type hints (from typing import List, Dict, Optional, etc.)
Naming:
- snake_case for functions/variables
- CamelCase for classes (use sparingly)
- UPPERCASE for constants
Error Handling: Use try/except blocks with specific exceptions
Logging: Print statements should use colorama (Fore.COLOR)
Comments: Minimal comments, focusing on why not what
Functions: Include verbose, thorough docstrings for functions, especially for tools that can be called by the chatbot

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.
