obsidian-bases

Create and edit Obsidian Bases (.base files) with views, filters, formulas, and summaries. Use when working with .base files, creating database-like views of notes, or when the user mentions Bases, table views, card views, filters, or formulas in Obsidian.

Quality

Content

42%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The skill provides excellent actionability with concrete, executable YAML examples and comprehensive coverage of the Obsidian Bases format. However, it is severely over-long and monolithic—functioning as an exhaustive reference manual rather than a focused skill file. The lack of workflow guidance for creating/validating .base files and the absence of content separation into supporting files significantly reduce its effectiveness as a skill.

Suggestions

Split the function reference tables (Global, Date, String, Number, List, File functions) into a separate FUNCTIONS_REFERENCE.md file and link to it from the main skill.

Move the complete examples (Task Tracker, Reading List, Project Notes, Daily Notes Index) into an EXAMPLES.md file, keeping only one brief example inline.

Add an explicit workflow section at the top: 1) Identify target folder/tags, 2) Write the YAML, 3) Validate YAML syntax, 4) Save as .base file, 5) Verify rendering in Obsidian.

Remove the 'When to Use This Skill' and 'Overview' sections—this information belongs in frontmatter/description, not in the body content that consumes context window.

DimensionReasoningScore

Conciseness

The skill is extremely verbose at ~400+ lines, functioning as a comprehensive reference manual rather than a focused skill. It includes exhaustive function reference tables (string, number, list, date functions), operator tables, and property listings that Claude already knows or could infer. The 'When to Use This Skill' section and 'Overview' are unnecessary padding. Much of this content (e.g., all the function signatures) belongs in separate reference files, not inline.

1 / 3

Actionability

The skill provides fully executable, copy-paste ready YAML examples throughout. The complete examples (Task Tracker, Reading List, Project Notes, Daily Notes Index) are concrete and realistic. Filter syntax, formula syntax, and view configurations all include working code that Claude can directly use.

3 / 3

Workflow Clarity

The skill clearly documents the schema and syntax but lacks an explicit workflow for creating or editing .base files. There are no validation steps (e.g., how to verify YAML is valid, how to check the base renders correctly in Obsidian), no error recovery guidance, and no step-by-step process for creating a new base file from scratch. For a file-creation task, a clear sequence with validation would be valuable.

2 / 3

Progressive Disclosure

This is a monolithic wall of reference content with no separation into supporting files. The extensive function reference tables, complete examples, and common patterns should be split into separate files (e.g., FUNCTIONS.md, EXAMPLES.md, PATTERNS.md) with the SKILL.md serving as a concise overview. The external links at the bottom are to Obsidian docs, not to bundle files. Everything is crammed into one massive document.

Description

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 an excellent skill description that follows best practices closely. It uses third person voice, lists specific capabilities, includes a clear 'Use when...' clause with multiple natural trigger terms, and targets a distinct niche (Obsidian Bases) that is unlikely to conflict with other skills.

DimensionReasoningScore

Specificity

Lists multiple specific concrete actions: 'Create and edit Obsidian Bases', '.base files', 'views, filters, formulas, and summaries'. These are concrete, actionable capabilities.

3 / 3

Completeness

Clearly answers both 'what' (create and edit Obsidian Bases with views, filters, formulas, and summaries) and 'when' (explicit 'Use when...' clause covering .base files, database-like views, and multiple trigger terms).

3 / 3

Trigger Term Quality

Excellent coverage of natural terms users would say: '.base files', 'Bases', 'table views', 'card views', 'filters', 'formulas', 'Obsidian', 'database-like views of notes'. These are terms users would naturally use when requesting this functionality.

3 / 3

Distinctiveness Conflict Risk

Highly distinctive with a clear niche: Obsidian Bases and .base files are a very specific feature. The mention of the file extension, 'Obsidian', and specific view types (table views, card views) make it unlikely to conflict with other skills.
