knowledge-tool-contracts-and-registryCovers Blade 的 Tool/ToolInvocation/ToolResult 契约、createTool 工厂、TypeBox 参数边界、ToolRegistry、延迟工具发现与通用 Session 制品存储。
Knowledge Tool Contracts And Registry is an agent skill from echoVic/blade-code. Covers Blade 的 Tool/ToolInvocation/ToolResult 契约、createTool 工厂、TypeBox 参数边界、ToolRegistry、延迟工具发现与通用 Session 制品存储。 Navigate when: 定义新工具字段、修改 schema 转换或校验、调整工具注册/搜索/MCP 目录、排查 metadata 或 deferred tool 可见性。 Excludes: 实际执行阶段与重试循环(见 ../tool-execution-pipeline/)、具体领域工具行为(见相邻子节点)。 Keywords: ToolConfig, ToolKind, ToolResult, UnifiedToolInvocation, createTool, ToolRegistry, DeferredToolManager, TypeBox, schemaToFunctionSchema, SessionArtifactStore.
Its SKILL.md is about 1.9k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Agent Workflows, covering MCP servers. It works with Model Context Protocol. The repository describes itself as: AI-powered CLI coding agent with 20+ built-in tools, MCP support, and multi-model providers. The licence is MIT.
Read from SKILL.md and the folder at commit 30f8684. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md (its code samples are typescript).
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Knowledge Tool Contracts And Registry loads about 1.9k tokens when it runs. Until then it costs about 120 tokens; SKILL.md has 391 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add echoVic/blade-code --skill knowledge-tool-contracts-and-registry -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/knowledge-tool-contracts-and-registry, .gemini/skills/knowledge-tool-contracts-and-registry, .github/skills/knowledge-tool-contracts-and-registry and .opencode/skills/knowledge-tool-contracts-and-registry in your project.
SKILL.md names no scripts, command-line tools or credentials: Knowledge Tool Contracts And Registry is instructions for the agent only.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Knowledge Tool Contracts And Registry is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.9k tokens (SKILL.md is roughly 7.7k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
