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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00022 | $0.00342 |
| Opus 5 | $0.00011 | $0.00171 |
| Sonnet 5 | $0.00004 | $0.00068 |
| Haiku 4.5 | $0.00002 | $0.00034 |
Grade A, and why
built-in-assistants 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 4d 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
Built-in Assistants
ContextGo 适合普通用户的一点，是它不要求你第一天就自己拼完整个能力栈。
内置 Assistants 的作用，就是先给你一个已经可以工作的起点。
这些内置助手更像已经整理好的工作模式入口，而不是一堆等你自己拼装的零件。
它们适合什么时候用
适合：
- 第一次上手
- 还不清楚该怎么组合 runtime、skills 和自动化
- 想先体验某一类工作方式
不适合：
- 已经非常明确要自己定义一套专用能力包
它们和 Runtime 的区别
Runtime 决定的是“谁来执行”。
Built-in Assistant 决定的是“以什么工作方式开始”。
也就是说：
- runtime 是执行后端
- assistant 是工作模式入口
该怎么选
最简单的原则：
- 做通用任务：先选通用 Cowork assistant
- 做研究：先选更偏 research 的 assistant
- 做开发：先选 builder / engineering 风格 assistant

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.

built-in-assistants is an agent published in the GitHub repository contextgo/contextgo (54 stars, last pushed 3mo ago), licensed Apache-2.0. It adds 22 tokens to every session and 342 once invoked, about $0.0001 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.
