developer-code-organization

A code-organization guide for gh-aw, a Go project that can run GitHub Actions workflows. It describes how to arrange files, keep them focused, handle strings, and support different WebAssembly build variants.

In plain words
What is it for?
Use it when splitting or refactoring Go files, adding helpers, handling text, or maintaining code that differs between WebAssembly build variants.
Why use it?
It helps developers find the right place for new code and avoid large, hard-to-maintain files. It also distinguishes cleaning text for safety from changing its meaning or format.

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

developer-code-organization 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.

Table of Contents

File Organization Principles

The codebase follows clear patterns for organizing code by functionality rather than type. This section provides guidance on maintaining code quality and structure.

Prefer Many Small Files Over Large Ones

Organize code into focused files of 100-500 lines rather than creating large monolithic files.

Example:

create_issue.go (160 lines)
create_pull_request.go (238 lines)
create_discussion.go (118 lines)
Group by Functionality, Not by Type

Recommended approach:

create_issue.go            # Issue creation logic
create_issue_test.go       # Issue creation tests
add_comment.go             # Comment addition logic
add_comment_test.go        # Comment tests

Avoid:

models.go                  # All structs
logic.go                   # All business logic
tests.go                   # All tests

Excellent Patterns to Follow

Create Functions Pattern

One file per GitHub entity creation operation:

  • create_issue.go - GitHub issue creation logic
  • create_pull_request.go - Pull request creation logic
  • create_discussion.go - Discussion creation logic
  • create_code_scanning_alert.go - Code scanning alert creation

Benefits:

  • Clear separation of concerns
  • Easy to locate specific functionality
  • Prevents files from becoming too large
  • Facilitates parallel development

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.

developer-code-organization is a skill published in the GitHub repository github/gh-aw (5,050 stars, last pushed yesterday), licensed MIT. It adds 28 tokens to every session and 4,325 once invoked, about $0.0001 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.
