Content
35%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This skill provides useful reference information about the FirstData MCP server and its tools, but suffers from significant verbosity and organizational issues. Large sections (What FirstData Is, Typical Queries table, Description Quality Guidelines, Community) add little actionable value for Claude. The tool documentation is detailed on limitations but lacks concrete invocation examples showing actual parameters and responses.
Suggestions
Remove or drastically shorten the 'What FirstData Is', 'Typical Queries', 'Description Quality Guidelines', and 'Community' sections — these waste tokens on context Claude doesn't need to perform the task.
Add concrete tool invocation examples with actual parameters and expected response structures for at least `search_source` and `ask_agent` (e.g., show the exact tool call for finding China GDP data and what the response looks like).
Move the detailed MCP Tools Reference (with all limitations) to a separate reference file and keep only a brief tool selection decision tree in the main SKILL.md.
Add an explicit workflow with decision points: e.g., 'Start with search_source for keyword queries → if results insufficient, escalate to ask_agent → verify source details with get_source → optionally get_access_guide for navigation help'.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill is extremely verbose with significant unnecessary content. The 'What FirstData Is' section explains concepts Claude doesn't need (what a data navigator is, what primary sources are). The 'Typical Queries' table, 'Description Quality Guidelines' section, and 'Community' section are all unnecessary padding. The coverage bullet list and capabilities section largely repeat information Claude can infer from the tool descriptions. | 1 / 3 |
Actionability | The Quick Start section provides concrete MCP configuration commands and JSON config, which is good. The MCP Tools Reference documents real limitations and parameters. However, there are no executable end-to-end examples showing actual tool invocations with specific parameters and expected responses — the tool descriptions are reference-style rather than showing concrete usage patterns with real input/output. | 2 / 3 |
Workflow Clarity | There's an implicit workflow (configure → authenticate → select tool → use tool) but no explicit sequenced workflow with validation checkpoints. The skill doesn't clearly guide through error recovery (e.g., what to do when quota is exhausted, when authentication fails, or when search returns no results). The tool selection guidance ('browse the tool list and select the appropriate tool') is vague rather than providing a clear decision tree. | 2 / 3 |
Progressive Disclosure | There is one reference to a separate file (references/firstdata-register.md) and an external README link, which is good. However, the main SKILL.md contains too much inline content that could be split out — the full MCP tools reference with all limitations could be a separate reference file, and the Description Quality Guidelines section doesn't belong in the main skill file at all. The bundle has no files provided to verify the referenced path exists. | 2 / 3 |
