github-readme-override

github-readme-override is a skill for Claude Code, Codex from fabioc-aloha/Alex_Skill_Mall. It costs 28 tokens per session (710 once invoked), scanned A, original, MIT.

An explanation of how GitHub chooses which README file to show on a repository page when several README files exist. A README is the documentation shown to people visiting a project.

In plain words
What is it for?
Use it to diagnose unexpected repository documentation and decide whether to remove, rename, or link an overriding README.
Why use it?
It explains why an updated root README may not appear and shows where an overriding file can be located.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one.

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is ln -s ../README.md README.md.

Good fit Use it to diagnose unexpected repository documentation and decide whether to remove, rename, or link an overriding README.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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

github-readme-override 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.

How it starts

The opening of the file, as written. The whole thing — 110 lines — stays where its author put it; the contents beside it link to each section on GitHub.

GitHub README Override

Category: GitHub Time Saved: 30-60 minutes Battle-tested: Yes — multiple projects affected


The Problem

You update your root README.md with new documentation. You push to GitHub. The repo landing page still shows the old content — or worse, a completely different file.

Why It Happens

GitHub treats .github/README.md as a "community health file" and displays it on the repository landing page instead of the root README.md. This is documented behavior but surprising when you don't expect it.

The Hierarchy

GitHub displays the FIRST match found in this order:

1. .github/README.md     ← Overrides everything
2. README.md             ← Standard location
3. docs/README.md        ← Alternative location

The Fix

Option 1: Delete the override

git rm .github/README.md
git commit -m "Remove README override"
git push

Option 2: Rename it

# Keep the file but don't let it override
git mv .github/README.md .github/ABOUT.md
git commit -m "Rename to prevent override"
git push

Option 3: Symlink (if you want both)

# Make .github/README.md a symlink to root
cd .github
ln -s ../README.md README.md
git add README.md
git commit -m "Symlink README"
git push

Note: GitHub renders symlinks, but some Git clients handle them poorly on Windows.

When .github/README.md Is Intentional

Sometimes you want different content on the landing page vs. what developers see locally:

Use Case Root README .github/README
Internal tool Technical setup Public-facing overview
Template repo "How to use template" "What this template does"
Monorepo Navigation/workspace docs Project overview

Verification

# Check if override exists
ls -la .github/README.md

# See what GitHub will display
# Push and check the repo landing page

Common Symptoms

  • "I updated README but GitHub shows old content"
  • "My README looks different on GitHub vs. locally"
  • "README changes aren't showing up"

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.
