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 | $0.00330 | $0.00330 |
| Opus 5 | $0.00165 | $0.00165 |
| Sonnet 5 | $0.00066 | $0.00066 |
| Haiku 4.5 | $0.00033 | $0.00033 |
Grade A, and why
mysql-mcp-server 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 7d 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
AI / 协作者约定
MCP 与 Token 节约
修改 Tools / Resources / Prompts（server.tool、server.resource、server.prompt、工具描述、Zod 字段说明、getToolsDescription）时，须把 LLM 上下文体积 当作硬约束：在不影响安全与可理解性的前提下，优先更短的描述与更紧凑的返回。
要点：
- 工具 description：一句话，写清能力 + 关键约束（只读、须 WHERE、条数上限）；不写与 JSON Schema 重复的说明书。
- Zod
.describe()：能短则短；参数含义在 schema 类型已明时可省略赘述。 - 工具返回：紧凑 JSON；默认不附带调试字段。
- Resources：注册时的
description保持短；正文避免堆砌与describe_table重复的长注释（需要注释再查表工具）。 - Prompts：元数据描述短；正文步骤够用即可，避免与工具描述逐字重复。
- 新增工具：先评估能否合并进现有工具，避免
list_tools体积膨胀。

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.
