Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00053 | $0.06321 |
| Opus 5.5 | $0.00021 | $0.02528 |
| Sonnet 5.5 | $0.00011 | $0.01264 |
| Haiku 4.5 | $0.00005 | $0.00632 |
Grade A, and why
multi-platform-plugin-guide 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 1mo 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.
How it starts
The opening of the file, as written. The whole thing — 253 lines — stays where its author put it; the contents beside it link to each section on GitHub.
多平台插件开发指南（AI Inner OS）
本仓入口：优先执行文末 SumSec-Skills 发布清单（本仓）。前半部分保留 AI Inner OS 多平台矩阵作为参考；本仓还落地 OpenClaw / OpenCode / Hermes / DeepSeek Harness（DSH）/ Pi 专用入口。
上游矩阵参考：AI Inner OS 主仓根目录 CLAUDE.md。若本技能的通用平台说明与 AI Inner OS 主仓不一致，先更新上游矩阵，再同步本技能。
何时使用
- 修改
hooks/hooks.json、.claude-plugin/、.codex-plugin/、.cursor-plugin/、.agents/plugins/marketplace.json、根plugin.json、openclaw.plugin.json或 release 版本字段。 - 修改根
package.json的dsh.bundle.patch/ DSH keywords、dsh/cordis.patch.yml、dsh/README.md、scripts/validate-dsh.mjs或 profile bundle 安装说明。 - 修改根
package.json的pi/pi-packagekeyword、pi/README.md、.pi/settings.json、scripts/plugin-skill-roots.mjs或scripts/validate-pi.mjs。 - 修改
hooks/、codex/、cursor/下的 hook 适配器，或共享库hooks/lib/。 - 更新必须和 manifest 保持一致的安装文档，例如
cursor/README.md、docs/install-cursor.md、codex/README.md、docs/install-codex.md。 - 准备跨平台 release、插件市场发布、插件缓存更新或多平台能力对齐。
官方文档优先
开发或审查任何平台适配前，先查看对应平台最新官方文档。本技能只记录本仓库当前约定；如果官方规范变化，以官方文档为准，再同步更新仓库实现、CLAUDE.md 和本技能。
| 平台 | 官方开发指南 |
|---|---|
| Claude Code | Plugins reference |
| Codex | Build plugins |
| Cursor | Plugins Reference |
| OpenClaw | Building plugins、Skills |
| OpenCode | Plugins |
| Hermes Agent | Plugins、Skills System |
| DeepSeek Harness | deepseek-ai/deepseek-harness、@deepseek-ai/dsh；本仓当前按 0.1.0-rc.6 验证，该包仍为 prerelease，升级前必须重新检查 package manifest、profile 与 Cordis patch contract。 |

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.

multi-platform-plugin-guide is a skill published in the GitHub repository SummerSec/SumSec-Skills (8 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 53 tokens to every session and 6,321 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings.
