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.
npx agentmods add instructions/abra5umente/api-proxy/claude-mdgit clone --depth 1 https://github.com/abra5umente/api-proxyWhat 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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00321 | $0.00321 |
| Opus 5 | $0.00161 | $0.00161 |
| Sonnet 5 | $0.00064 | $0.00064 |
| Haiku 4.5 | $0.00032 | $0.00032 |
Grade A, and why
api-proxy 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 2d 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.
What it actually says
CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
Project Overview
API Proxy service that routes requests through a residential IP for APIs that block cloud/datacenter IPs (e.g., Reddit). Built with FastAPI and httpx.
Request flow: Claude Container → Cloudflare Tunnel → This Proxy → Target API
Development Commands
# Run locally
uvicorn app:app --host 0.0.0.0 --port 8000
# Run with auto-reload during development
uvicorn app:app --reload --port 8000
# Build Docker image
docker build -t api-proxy .
# Run Docker container
docker run -p 8000:8000 -e PROXY_AUTH_TOKEN=your-token api-proxy
Architecture
Single-file FastAPI application (app.py) with two endpoints:
GET /health- Unauthenticated health checkPOST /proxy- Authenticated proxy endpoint (requiresX-Proxy-Tokenheader)
Environment variables:
PROXY_AUTH_TOKEN(required) - Auth token for/proxyrequestsALLOWED_DOMAINS- Comma-separated domain whitelist (empty = allow all)PROXY_TIMEOUT- Request timeout in seconds (default: 30)
Domain validation: is_domain_allowed() checks against whitelist, supports subdomains (e.g., reddit.com allows oauth.reddit.com).
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.

api-proxy CLAUDE.md is an instructions file published in the GitHub repository abra5umente/api-proxy (17 stars, last pushed 8mo ago), licensed MIT. It adds 321 tokens to every session, about $0.0016 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.
