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 | $0.00134 | $0.01925 |
| Opus 5.5 | $0.00054 | $0.00770 |
| Sonnet 5.5 | $0.00027 | $0.00385 |
| Haiku 4.5 | $0.00013 | $0.00193 |
Grade A, and why
knowledge-extension-ecosystem 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.

Module Structure
扩展生态先在 source project 上发现配置与资源，再由 Workspace 级注册表完成插件整合， 最后冻结为 Session 私有视图；MCP 和 LSP 还会在 Session 初始化时创建独立连接与进程。

Gotchas
- Workspace Trust 只决定项目扩展资源能否被发现，配置型 Hook 还必须通过独立的精确摘要信任；信任 workspace 不等于信任其中的命令、Prompt 或 HTTP Hook(
packages/cli/src/skills/SkillRegistry.ts,packages/cli/src/hooks/HookTrustService.ts) - source project 是 MCP/LSP/插件配置身份，execution workspace 是 worktree 中实际执行工具和启动 LSP 的路径；将两者混用会让 MCP 默认 cwd、MCP roots 或 LSP 文件边界指向错误 checkout(
packages/cli/src/agent/runtime/SessionRuntime.ts,packages/cli/src/mcp/resolveWorkspaceMcpConfig.ts,packages/cli/src/lsp/LspSessionManager.ts) - 插件刷新先清空再整批重注入 Workspace 注册表，但已创建 Session 使用 Skills、命令、Hooks 和 LSP 的快照，不应被刷新中的可变对象追改(
packages/cli/src/plugins/PluginIntegrator.ts,packages/cli/src/agent/resources/WorkspaceAgentResources.ts) - 插件整合阶段只登记 MCP/LSP 定义数量，不建立连接；实际 MCP client 和 LSP process 都延迟到精确 Session 中创建(
packages/cli/src/plugins/PluginIntegrator.ts,packages/cli/src/agent/runtime/SessionRuntime.ts) - MCP、LSP、Skills 和命令均按 workspace 或 Session 隔离，不能以无参数全局单例作为多项目调用的权威来源(
packages/cli/src/mcp/McpRegistry.ts,packages/cli/src/skills/SkillRegistry.ts,packages/cli/src/slash-commands/custom/CustomCommandRegistry.ts)
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.

knowledge-extension-ecosystem is a skill published in the GitHub repository echoVic/blade-code (181 stars, last pushed 3d ago), licensed MIT. It adds 134 tokens to every session and 1,925 once invoked, about $0.0005 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 2026-09-03.
