Knowledge Base Skill

The skill only involves creating and updating a Markdown knowledge base in a local folder, does not execute terminal commands, and aligns with least privilege. The skill documentation explicitly requires asking the user before acting when ambiguous (e.g., new KB vs add note vs cleanup), and emphasizes updating the index synchronously, reflecting data-flow transparency. It does not handle sensitive data and has no external side effects. However, it relies on underlying MCP server tools (like write_file, edit_block) which may have broader filesystem access, and the skill itself provides no finer-grained permission control. Although the skill itself is low risk, the overall MCP server functionality (like terminal control) is high-risk, increasing overall trust concerns. Hence, a deduction is appropriate.

The skill documentation provides detailed workflows and a checklist, but there is no test or executable evidence. Static review cannot confirm the skill always works as expected with different MCP server tools. The documentation mentions using specific tools (e.g., start_search, get_file_info) for maintenance but does not provide error handling or failure feedback mechanisms. Therefore, key-path reliability lacks verification, leading to a deduction.

The skill has clear usage scenarios aimed at creating, updating, and maintaining Markdown knowledge bases. Trigger words are explicit (e.g., 'knowledge base', 'KB', 'add a note') which helps semantic triggering. However, the skill does not explicitly state environment requirements (e.g., dependency on MCP server tools) or non-fit scenarios (e.g., if user needs a relational database). For Chinese users, the skill mainly handles English content but does not rely on unreachable overseas services, so domestic usability is good. Deduction due to incomplete boundaries and trigger conditions.

The skill documentation is well-structured with clear information architecture: core principles, folder structure, naming rules, frontmatter requirements, INDEX.md and _topic.md explanations, detailed workflows, and a checklist. Installation/dependency notes are not in the skill itself but available in README. Version and changelog are not in the skill but the repository manages versions. Known limitations are not listed in the skill but SECURITY.md covers the server's security model. Overall documentation is good, but missing skill-specific version history and maintenance responsibility. Hence, deduction.

The skill instructs the agent to create and maintain a knowledge base with expected output of compliant Markdown files and index. The documentation provides clear steps and likely achieves the goal. However, static review does not verify actual output, lacking evidence of direct usability or comparative benefit. The core task (create/maintain KB) is likely achievable, but marginal value and alternative comparison evidence are limited. Therefore, score is near 7, not satisfied.

The repository has CI workflows (e.g., codespell.yml) and test files (e.g., ab-test.test.js, edit-block-performance.js), but these target the MCP server, not this skill. No third-party execution evidence directly verifying the skill's behavior is found. Static review can only confirm documentation existence, not actual effectiveness. Hence, evidence coverage is insufficient, leading to a low score.
