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 | $0.01069 | $0.01069 |
| Opus 5 | $0.00535 | $0.00535 |
| Sonnet 5 | $0.00214 | $0.00214 |
| Haiku 4.5 | $0.00107 | $0.00107 |
Grade A, and why
prompt-tower.nvim 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 9d 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.

Project Overview
prompt-tower.nvim is a Neovim plugin for creating AI-ready context from codebases. It allows users to select files and generate structured prompts for AI assistants.
Development Commands
Use these Make commands for development workflow:
# Testing
make test # Run all tests using plenary.nvim
make test-verbose # Run tests with verbose output
make test-file FILE=path # Run specific test file
# Code Quality
make lint # Run Selene linting
make format # Format code with StyLua
make format-check # Check formatting without changes
make ci # Run all CI checks (format + lint + test)
# Development Setup
make dev-setup # Setup development environment
make install-deps # Show dependency installation info
Architecture Overview
Core Architecture Pattern
The plugin follows a layered architecture:
- Plugin Layer (
plugin/prompt-tower.lua): Registers Neovim user commands - Main Interface (
lua/prompt-tower/init.lua): Primary API and command handlers - Configuration (
lua/prompt-tower/config.lua): Centralized configuration management with validation - Services Layer (
lua/prompt-tower/services/): Business logic for workspace and file operations - Models Layer (
lua/prompt-tower/models/): Data structures and domain objects
Key Components
Configuration System (config.lua)
- Centralized configuration with deep merging of user options
- Built-in validation for all configuration values
- Supports dot notation for nested config access (
config.get_value('clipboard.register')) - Default configuration covers ignore patterns, output formatting, project tree settings, and clipboard behavior
Workspace Management (services/workspace.lua)
- Automatically detects project roots using common markers (
.git,package.json,Makefile, etc.) - Manages multiple workspaces and file selection state
- Integrates with file discovery service for scanning directories
- Handles relative path calculation and workspace switching
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.

prompt-tower.nvim CLAUDE.md is an instructions file published in the GitHub repository kylesnowschwartz/prompt-tower.nvim (16 stars, last pushed 1y ago), licensed MIT. It adds 1,069 tokens to every session, about $0.0053 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.
