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.

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 | $0.01936 | $0.01936 |
| Opus 5 | $0.00968 | $0.00968 |
| Sonnet 5 | $0.00387 | $0.00387 |
| Haiku 4.5 | $0.00194 | $0.00194 |
Grade A, and why
git-proxy AGENTS.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.
How it starts
The opening of the file, as written. The whole thing — 404 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md — GitProxy
Project Overview
GitProxy is a Git HTTP proxy that intercepts Git operations (primarily git push) and enforces organizational policies before allowing changes to reach the actual Git host.
It acts as:
- A policy enforcement engine (via processors and plugins)
- A review/approval gate (manual or automated)
- A proxy server for Git operations
- A UI + API layer for reviewing, approving, and auditing pushes
The core design principle is a chain-of-processors architecture where each Git action flows through ordered processing steps.

High-Level Architecture
GitProxy consists of four main components:
Contributor (git push)
↓
HTTP Proxy (/src/proxy)
↓
Action Chain (Processors + Plugins)
↓
Service API (/src/service)
↓
Database (audit, users, repos, approvals)
↓
Web UI (/src/ui)
1. Proxy Server (/src/proxy)
Express-based HTTP proxy that:
- Intercepts Git operations
- Parses requests into an
Action - Executes the appropriate Action Chain
- Blocks, rejects, or queues for approval
Core concepts:
- Action — Represents a Git operation (push/pull/default)
- Chain — Ordered list of processors
- Processor (Step) — A single policy enforcement unit
- Plugin — Custom processor injected externally
2. Service API (/src/service)
Express application responsible for:
- UI communication
- Authentication (Passport strategies)
- Database access
- Approval/rejection workflows
Default port: 8080
Authentication strategies supported:
- Local
- ActiveDirectory
- OpenID Connect
3. Configuration (/src/config)
Loads and validates proxy.config.json.

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.

git-proxy AGENTS.md is an instructions file published in the GitHub repository finos/git-proxy (243 stars, last pushed 2d ago), licensed Apache-2.0. It adds 1,936 tokens to every session, about $0.0097 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.
