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 concise yet comprehensive, with domain-specific terminology that minimizes conflict risk. The note about being 'grounded in local v3.1 docs — zero speculation' adds useful context about the skill's reliability.
| 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, CodeMode, Tool Search, testing, debugging. These are 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 unique to this ecosystem. Unlikely to conflict with generic Python or web server skills. | 3 / 3 |
Total | 12 / 12 Passed |
Implementation
85%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 routing/overview skill that effectively serves as an index into a large FastMCP v3 knowledge base. Its strengths are excellent progressive disclosure, clear decision flowcharts, actionable code examples, and a comprehensive trigger matrix. Its main weakness is moderate redundancy — the reference files are listed both in the trigger matrix and again in a dedicated section, and the version gating section adds token weight that could potentially live in a reference file.
Suggestions
Consider moving the detailed 'Version Gating' section and the full 'Reference Files' listing into a reference file to reduce token overhead, since the trigger matrix already links to all references.
The 'Related Skills' section partially overlaps with trigger matrix entries (e.g., testing, CLI usage) — consider consolidating to avoid redundancy.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill is mostly efficient with good use of tables and diagrams, but the extensive trigger matrix, three mermaid flowcharts, version gating section, and full reference file listing add significant token weight. Some of this (like listing all 13 reference files with descriptions after already linking them in the trigger matrix) is redundant. | 2 / 3 |
Actionability | The quick-start examples are fully executable and copy-paste ready. The trigger matrix provides concrete mappings from intent to reference files. The v3 API corrections table gives specific wrong→right patterns. The environment detection commands at the top are immediately actionable. | 3 / 3 |
Workflow Clarity | The mermaid decision trees provide clear, unambiguous workflows for choosing providers, transports, and auth approaches. The trigger matrix acts as a clear routing mechanism — when intent matches, load the specific reference file. For a skill that primarily routes to reference files, this is well-structured with clear decision points. | 3 / 3 |
Progressive Disclosure | Excellent progressive disclosure — the SKILL.md serves as a concise overview and routing layer, with all detailed content properly delegated to 13+ reference files via one-level-deep links. The trigger matrix, flowcharts, and reference file section all provide clear navigation to deeper content. | 3 / 3 |
