What is tiygate AGENTS.md?

Repository instructions for TiyGate, an open-source Rust AI Gateway organized as a Cargo workspace with eight crates and a web admin console.

Use them when working on TiyGate so changes fit the crate boundaries, web console, documentation, scripts, and testing layout.

They give coding agents the project’s structure, engineering rules, build and test commands, and naming conventions.

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.

Model	Per session	Once invoked
Fable 5.1	$0.01187	$0.01187
Opus 5.5	$0.00475	$0.00475
Sonnet 5.5	$0.00237	$0.00237
Haiku 4.5	$0.00119	$0.00119

Security

Grade A, and why

tiygate 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 2mo 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.

Repository Guidelines

Contributor guide for TiyGate, an open-source Rust AI Gateway. Preserve the crate layering described below; it is intentional and enforced.

Project Structure & Module Organization

This repository is a Cargo workspace with 8 crates and an embedded admin console:

crates/core contains canonical IR, traits, and pipeline code. It must stay zero-I/O and free of concrete provider, protocol, or database dependencies.
crates/protocols implements protocol codecs for chat completions, messages, responses, Gemini, and embeddings.
crates/providers stores built-in provider metadata and auth; crates/provider-bedrock isolates heavy AWS Bedrock SDK dependencies.
crates/store, crates/cache, crates/admin, and crates/server cover config storage, embedding cache, Admin REST/OAuth, and the tiygate binary.
webui/ is the React + TypeScript + Vite admin console, embedded with rust-embed and served at /admin/ui.
docs/ holds architecture and protocol capability docs; scripts/ contains helper checks such as verify-deps.sh.
Tests live in crates/<crate>/tests/ for integration tests and inline #[cfg(test)] modules for unit tests.

Engineering Principles

Keep changes aligned with three project constraints:

Reliability first: keep the request hot path resilient with fallback budgets, circuit breakers, ingress limits, graceful drain, and telemetry/logging off the hot path.
Extensible by design: add providers, protocols, routing strategies, cache backends, and log sinks through existing trait/registration boundaries instead of central rewrites.
Maintainable layering: keep core as canonical IR + traits only, use the IR to avoid N×N protocol coupling, document lossy protocol behavior in docs/protocol-capability-matrix.md, and isolate heavy dependencies in dedicated crates.

Build, Test, and Development Commands

Run commands from the repository root. Use make help for the full list.

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.
