Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md.

This is coulsontl/ai-toolbox's own configuration. It tells Codex and OpenCode how to work on ai-toolbox 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 ai-toolbox configures →

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

ai-toolbox AGENTS.md 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 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.

Makes network callslowCapability

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

- 原因不是“风格统一”,而是实战兼容性:某些机器上 `reqwest + Schannel` 会在 TLS 建连阶段直接报 `SEC_E_NO_CREDENTIALS` / “安全包中没有可用的凭证”,表现为浏览器、Node、curl 正常,但 Rust `send()` 在真正发出业务请求前就失败。

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.
