helpers: Instructions file for Claude Code

CLAUDE.md

helpers CLAUDE.md is an instructions file for Claude Code from gpsaggese/helpers. It costs 1,340 tokens per session, scanned A, original, Apache-2.0.

A repository instruction file describing the structure, conventions, and testing approach of the Helpers Python library. It guides Claude Code when working in that repository.

In plain words
What is it for?
Use it when maintaining the Helpers codebase, especially its utility modules, data-processing code, integrations, and tests.
Why use it?
It gives the coding agent project-specific context instead of making it infer how files and tests are organized.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: mentions CLAUDE.md; mentions Claude Code.

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

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

helpers 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 yesterday.

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.

Repository Architecture

Core Structure

This is the helpers repository, a foundational Python library providing utilities, development tools, and infrastructure components for a larger ecosystem. The codebase follows a modular architecture with these key components:

  • helpers/: Core utility modules (100+ modules) following h<name> naming convention organized into categories:
    • Core Infrastructure: hdbg, hio, hsystem, hserver, henv - debugging, I/O, system operations
    • Data Processing: hpandas, hdataframe, hnumpy, hparquet, hcsv - data manipulation and analysis
    • Testing Framework: hunit_test, hpytest, hcoverage, hplayback - comprehensive testing utilities
    • External Services: haws, hs3, hgit, hdocker, hchatgpt, hllm - cloud and tool integrations
    • Caching & Performance: hcache, hcache_simple, hjoblib, htimer - performance optimization
    • Command-line & Parsing: hparser: argument parsing and CLI utilities
    • Text & Markdown: hmarkdown* family, hstring, htext_protect - text processing and markdown utilities
  • config_root/: Configuration system with Config class and builders for hierarchical configuration management
  • linters/: Pluggable linting framework with custom linters for code quality (amp_black, amp_isort, etc.)
  • dev_scripts_helpers/: Development automation scripts organized by functionality (git, docker, documentation, etc.)

Task System Architecture

The repository uses pyinvoke for task automation with a modular task system:

  • tasks.py: Entry point that imports all task modules
  • helpers/lib_tasks_*.py: Task modules organized by domain (docker, git, pytest, lint, etc.)
  • Tasks are decorated with @task and accessible via invoke <task_name>

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.
