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 | $0.01276 | $0.01276 |
| Opus 5 | $0.00638 | $0.00638 |
| Sonnet 5 | $0.00255 | $0.00255 |
| Haiku 4.5 | $0.00128 | $0.00128 |
Grade A, and why
Promptheus GEMINI.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 5d 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.

Promptheus Project Context
This document provides a comprehensive overview of the Promptheus project, its architecture, and development conventions to be used as instructional context.
1. Project Overview
Promptheus is a sophisticated, AI-powered command-line interface (CLI) tool written in Python. Its primary purpose is to help users craft and refine prompts. The tool takes a user's initial prompt and, through a series of AI-driven steps, outputs a better, more effective prompt for the user to then take and use with any Large Language Model (LLM).
Core Features:
- Multi-Provider Support: It uses LLM backends (Google, Anthropic Claude, OpenAI, Groq, Qwen, GLM) for its internal refinement process.
- Adaptive Interaction: The tool intelligently detects the user's task type:
- Generation Tasks: It offers to ask clarifying questions to add detail.
- Analysis Tasks: It performs an automatic, non-interactive "light refinement" to improve the prompt's clarity.
- Iterative Refinement: Users can "tweak" a generated prompt with natural language commands in an interactive loop.
- Rich Interactive UI: The interface is built with
richandquestionary, providing a polished and user-friendly experience. - Flexible Configuration: Configuration is handled via a clear hierarchy: CLI arguments (
--provider), environment variables (PROMPTHEUS_PROVIDER), and.envfiles. - Prompt History: All refined prompts are automatically saved to a history file for later reference and reuse.
- Subcommand Interface: Provides dedicated subcommands for utility functions like
list-models,validate, andhistoryfor a clean and modern CLI experience. - Dynamic Model Discovery: Model information is dynamically fetched from the models.dev API and cached locally for 24 hours.
Architecture:
The project follows a modular and modern Python architecture:
src/promptheus/main.py: The main application entry point. It handles parsing command-line arguments, orchestrates the refinement workflow, and manages the user interface.src/promptheus/cli.py: Defines the entire command-line interface, including all subcommands and their arguments, using Python'sargparsemodule.src/promptheus/commands.py: Implements the logic for the utility subcommands (list-models,validate,template,history).src/promptheus/config.py: A dedicated configuration manager that detects and validates API keys and settings from environment variables and.envfiles. It usesproviders.jsonfor provider-specific metadata.src/promptheus/providers.py: The core abstraction layer. It defines anLLMProviderabstract base class and concrete implementations (GeminiProvider,AnthropicProvider,OpenAICompatibleProvider, etc.).src/promptheus/prompts.py: Stores the system instruction templates that guide the internal LLM calls for question generation, refinement, and tweaking.src/promptheus/history.py: Manages persistent storage of prompt history with timestamp tracking.
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.

Promptheus GEMINI.md is an instructions file published in the GitHub repository abhichandra21/Promptheus (17 stars, last pushed 5mo ago), licensed MIT. It adds 1,276 tokens to every session, about $0.0064 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 2026-08-30.
