fastmcp-creator
Use when building, extending, or debugging FastMCP v3 Python MCP servers. Activates on FastMCP tool/resource/prompt creation, provider and transform implementation (CodeMode, Tool Search), auth setup (MultiAuth, PropelAuth), client SDK usage, nginx reverse proxy deployment, Prefab Apps, and testing. Grounded in local v3.1 docs — zero speculation.

Quality
Discovery
100%Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.
This is a strong, well-crafted skill description that clearly identifies its niche (FastMCP v3 Python MCP servers), lists numerous specific capabilities and trigger terms, and explicitly states when it should be activated. The description is dense with relevant keywords without being verbose, and the specificity of named features (CodeMode, PropelAuth, MultiAuth, Prefab Apps) makes it highly distinctive. The only minor note is the phrase 'zero speculation' which is slightly promotional but doesn't detract meaningfully.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple specific concrete actions: building/extending/debugging FastMCP v3 servers, tool/resource/prompt creation, provider and transform implementation with named examples (CodeMode, Tool Search), auth setup (MultiAuth, PropelAuth), client SDK usage, nginx reverse proxy deployment, Prefab Apps, and testing. | 3 / 3 |
Completeness | Explicitly answers both 'what' (building/extending/debugging FastMCP v3 Python MCP servers with specific capabilities listed) and 'when' (opens with 'Use when building, extending, or debugging' and specifies 'Activates on' with detailed trigger scenarios). | 3 / 3 |
Trigger Term Quality | Excellent coverage of natural trigger terms users would say: FastMCP, MCP servers, tool/resource/prompt creation, auth, PropelAuth, MultiAuth, nginx reverse proxy, client SDK, Prefab Apps, testing, CodeMode, Tool Search. These are highly specific terms a developer working with FastMCP would naturally use. | 3 / 3 |
Distinctiveness Conflict Risk | Highly distinctive — targets a very specific technology (FastMCP v3) with named features (CodeMode, PropelAuth, MultiAuth, Prefab Apps) that are unlikely to overlap with any other skill. The mention of being 'grounded in local v3.1 docs' further narrows its niche. | 3 / 3 |

Implementation
72%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is a well-structured skill that excels as a routing/dispatch layer for a complex topic with many sub-domains. Its greatest strengths are the comprehensive trigger matrix, actionable code examples, and excellent progressive disclosure to reference files. The main weaknesses are moderate verbosity (mermaid diagrams could be more compact) and lack of explicit validation/verification steps in the workflows presented at the top level.
Suggestions
Consider replacing the three mermaid flowcharts with compact decision tables to save tokens — the trigger matrix table format already works well and is more token-efficient.
Add a brief end-to-end workflow with validation checkpoints (e.g., 'Build → Test → Deploy' sequence with explicit verification steps) to improve workflow clarity at the top level.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill is mostly efficient with good use of tables and diagrams, but the mermaid flowcharts add significant token cost for information that could be conveyed more compactly as decision tables. The version gating section and reference file listing are somewhat verbose, though they do provide useful information. | 2 / 3 |
Actionability | The quick-start examples are fully executable and copy-paste ready with correct Python syntax. The trigger matrix provides concrete file references for every use case, the v3 API corrections table gives specific wrong→right patterns, and the environment detection commands are immediately runnable. | 3 / 3 |
Workflow Clarity | The trigger matrix provides a clear lookup workflow (match intent → load reference file), and the decision flowcharts guide provider/transport/auth selection well. However, there are no validation checkpoints or feedback loops for multi-step processes like building and deploying a server — the skill delegates all detailed workflows to reference files without showing the overall sequence. | 2 / 3 |
Progressive Disclosure | Excellent progressive disclosure structure: the SKILL.md serves as a concise overview and routing layer with a well-organized trigger matrix pointing to 13+ clearly-named reference files, all one level deep. Navigation is well-signaled with both the table and the reference files section, and related skills are cross-referenced. | 3 / 3 |
