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.

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 | $0.00070 | $0.00374 |
| Opus 5.5 | $0.00028 | $0.00150 |
| Sonnet 5.5 | $0.00014 | $0.00075 |
| Haiku 4.5 | $0.00007 | $0.00037 |
Grade A, and why
cordis-plugin-sofagent-inject 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
cordis-plugin-sofagent-inject
启动注入企业约束——四层加载链（seam: agent/pre-step）——桥接 @sofagent/inject buildConstrainedSystemPrompt
用途
装上之后：模型每次请求前带上企业铁律 / 反思 / 用户规则 / 知识库（四层加载链）。什么时候用：希望 Agent 一开口就带着公司的规矩，不必每次交代背景。
接入点（seam: agent/pre-step）：桥接 @sofagent/inject，缺依赖时该能力静默跳过；接入形态（声明 / 实现）见 SEAMS.md。
本插件随 sofagent 主线版本发布（SkillHub 通道：skillhub install cordis-plugin-sofagent-inject 安装与检索；npm 通道未开通）。版本号与 sofagent 主线对齐。

What ships with it
5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

cordis-plugin-sofagent-inject is a skill published in the GitHub repository KongFangXun/sofagent (54 stars, last pushed 4d ago), licensed MIT. It adds 70 tokens to every session and 374 once invoked, about $0.0003 per session on Opus 5.5. 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.
