Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions AGENTS.md; mentions Codex.

This is router-for-me/CLIProxyAPI's own configuration. It tells Codex and OpenCode how to work on CLIProxyAPI itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything CLIProxyAPI configures →

About the project

CLIProxyAPI is a proxy server that exposes compatible OpenAI, Gemini, Claude, and Codex APIs for models accessed through command-line services and accounts. It lets clients and SDKs use these providers through a common local API interface. The catalogue contains instructions for using CLIProxyAPI.

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

CLIProxyAPI 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 22d 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.

The opening of the file, as written. The whole thing — 64 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md

Go 1.26+ proxy server providing OpenAI/Gemini/Claude/Codex compatible APIs with OAuth and round-robin load balancing.

Repository

Commands

gofmt -w . # Format (required after Go changes)
go build -o cli-proxy-api ./cmd/server # Build
go run ./cmd/server # Run dev server
go test ./... # Run all tests
go test -v -run TestName ./path/to/pkg # Run single test
go build -o test-output ./cmd/server && rm test-output # Verify compile (REQUIRED after changes)
  • Common flags: --config <path>, --tui, --standalone, --local-model, --no-browser, --oauth-callback-port <port>

Config

  • Default config: config.yaml (template: config.example.yaml)
  • .env is auto-loaded from the working directory
  • Auth material defaults under auths/
  • Storage backends: file-based default; optional Postgres/git/object store (PGSTORE_*, GITSTORE_*, OBJECTSTORE_*)

Architecture

  • cmd/server/ — Server entrypoint
  • internal/api/ — Gin HTTP API (routes, middleware, modules)
  • internal/api/modules/amp/ — Amp integration (Amp-style routes + reverse proxy)
  • internal/thinking/ — Main thinking/reasoning pipeline. ApplyThinking() (apply.go) parses suffixes (suffix.go, suffix overrides body), normalizes config to canonical ThinkingConfig (types.go), normalizes and validates centrally (validate.go/convert.go), then applies provider-specific output via ProviderApplier. Do not break this "canonical representation → per-provider translation" architecture.
  • internal/runtime/executor/ — Per-provider runtime executors (incl. Codex WebSocket)
  • internal/translator/ — Provider protocol translators (and shared common)
  • internal/registry/ — Model registry + remote updater (StartModelsUpdater); --local-model disables remote updates
  • internal/store/ — Storage implementations and secret resolution
  • internal/managementasset/ — Config snapshots and management assets
  • internal/cache/ — Request signature caching
  • internal/watcher/ — Config hot-reload and watchers
  • internal/wsrelay/ — WebSocket relay sessions
  • internal/usage/ — Usage and token accounting
  • internal/home/ — CLIProxyAPIHome control plane integration (bootstrap, RESP communication, dispatch coordination)
  • internal/tui/ — Bubbletea terminal UI (--tui, --standalone)
  • sdk/cliproxy/ — Embeddable SDK entry (service/builder/watchers/pipeline)
  • test/ — Cross-module integration tests

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.
