Lists multiple concrete actions: 'Find official portals, APIs, and download paths', 'authority comparison', and 'site navigation guidance'. Also specifies the types of sources covered (governments, international organizations, research institutions).

Clearly answers 'what' (find official portals, APIs, download paths with authority comparison and navigation guidance) and 'when' (explicit 'Use when' clause with three specific trigger scenarios). Both dimensions are well-covered.

Includes natural phrases users would say: 'where to find this data from an official source', 'which source is more authoritative', 'how to cite primary data'. Also includes relevant keywords like 'portals', 'APIs', 'download paths', 'official', 'authoritative', 'primary data sources'.

Occupies a clear niche around finding authoritative/official data sources, which is distinct from general data analysis, web search, or document processing skills. The focus on authority comparison and primary source identification makes it unlikely to conflict with other skills.

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.

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.

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.

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.
