uithub

A command that retrieves the structure and selected documentation of a GitHub repository without cloning it to your computer.

In plain words
What is it for?
Inspecting a repository tree, README, and other relevant documentation based on a GitHub URL, repository name, or question.
Why use it?
It provides focused repository context while avoiding a full local checkout.

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.

Clone the repo
git clone --depth 1 https://github.com/minghinmatthewlam/agent-guards
Per session 0 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 484 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 1 finding. Scan, not verified.
Origin original No closer match found in the catalogue.
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

uithub scanned grade A with 1 finding 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 3d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

What it actually says

Purpose: fetch UiThub repo context for a GitHub project without cloning.

Inputs

  • $REPO_URL (required): GitHub URL or owner/repo slug.
  • $CONTEXT (optional): focus areas/questions to guide which files to fetch.

Flow

  1. Validate $REPO_URL. If missing or invalid, ask the user for a correct value.
  2. Normalize to <owner>/<repo> and extract any path hints from $REPO_URL.
  3. Determine the repository’s default branch (e.g., curl -H "Accept: application/vnd.github.v3+json" https://api.github.com/repos/<owner>/<repo> | jq -r '.default_branch'). If discovery fails, fall back to main but mention the assumption.
  4. Fetch structure only:
    curl "https://uithub.com/<owner>/<repo>?accept=text/plain&omitFiles=true" > tree.txt
  5. Pull key docs (adjust lines) using the discovered branch:
    curl "https://uithub.com/<owner>/<repo>/tree/$BRANCH/README.md?accept=text/plain&plain=1&lines=200" > readme.txt
    • Fetch other docs (CONTRIBUTING.md, docs/overview.md, etc.) when $CONTEXT suggests.
    • After each curl, check the output (status code, byte size). Retry with plain=1, ?path=..., or https://raw.githubusercontent.com/<owner>/<repo>/$BRANCH/... if the response is empty or a 404.
  6. Capture code slices guided by $CONTEXT:
    • Start with curl "https://uithub.com/<owner>/<repo>/tree/$BRANCH/<path>?accept=text/plain&plain=1&lines=200" for targeted files.
    • For larger sections, use curl "https://uithub.com/<owner>/<repo>?accept=text/plain&path=<path>", then trim locally.
    • If UiThub still returns nothing, fall back to https://raw.githubusercontent.com/<owner>/<repo>/$BRANCH/<path>.
  7. Summarize what each artifact reveals and note gaps needing further UiThub pulls or a full clone, explicitly tying the findings back to $CONTEXT.

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.
