Installation

Quick Install with Auto-Configuration (Claude Desktop)

New in v2.0! Configure Claude Desktop automatically with one command:

# Install and configure in one step
uvx --from obsidian-mcp obsidian-mcp-configure --vault-path /path/to/your/vault

This command will:

  • āœ… Automatically find your Claude Desktop config

  • āœ… Add the Obsidian MCP server

  • āœ… Migrate old REST API configs to v2.0

  • āœ… Create a backup of your existing config

  • āœ… Work on macOS, Windows, and Linux

Manual Configuration

  1. Locate your Obsidian vault:

    • Find the path to your Obsidian vault on your filesystem

    • Example: /Users/yourname/Documents/MyVault or C:\Users\YourName\Documents\MyVault

  2. Configure your AI tool:

    Edit your Claude Desktop config file:

    • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

    • Windows: %APPDATA%\Claude\claude_desktop_config.json

    {
      "mcpServers": {
        "obsidian": {
          "command": "uvx",
          "args": ["obsidian-mcp"],
          "env": {
            "OBSIDIAN_VAULT_PATH": "/path/to/your/obsidian/vault"
          }
        }
      }
    }

    Add to your Cursor settings:

    • Project-specific: .cursor/mcp.json in your project directory

    • Global: ~/.cursor/mcp.json in your home directory

    {
      "mcpServers": {
        "obsidian": {
          "command": "uvx",
          "args": ["obsidian-mcp"],
          "env": {
            "OBSIDIAN_VAULT_PATH": "/path/to/your/obsidian/vault"
          }
        }
      }
    }

    Then: Open Settings → Cursor Settings → Enable MCP

    Edit your Windsurf config file:

    • Location: ~/.codeium/windsurf/mcp_config.json

    {
      "mcpServers": {
        "obsidian": {
          "command": "uvx",
          "args": ["obsidian-mcp"],
          "env": {
            "OBSIDIAN_VAULT_PATH": "/path/to/your/obsidian/vault"
          }
        }
      }
    }

    Then: Open Windsurf Settings → Advanced Settings → Cascade → Add Server → Refresh

  3. Restart your AI tool to load the new configuration.

That's it! The server will now be available in your AI tool with access to your Obsidian vault.

Note: This uses uvx which automatically downloads and runs the server in an isolated environment. Most users won't need to install anything else. If you don't have uv installed, you can also use pipx install obsidian-mcp and change the command to "obsidian-mcp" in the config.

Testing

Running Tests

# Run all tests
python tests/run_tests.py

# Or with pytest directly
pytest tests/

Tests create temporary vaults for isolation and don't require a running Obsidian instance.

Testing with MCP Inspector

  1. Set your vault path:

    export OBSIDIAN_VAULT_PATH="/path/to/your/vault"
  2. Run the MCP Inspector:

    npx @modelcontextprotocol/inspector python -m obsidian_mcp.server
  3. Open the Inspector UI at http://localhost:5173

  4. Test the tools interactively with your actual vault

Integration with Claude Desktop

For development installations, see the Development Installation section above.

Enhanced Error Handling

The server provides detailed, actionable error messages to help AI systems recover from errors:

Example Error Messages

Invalid Path:

Invalid note path: '../../../etc/passwd'. 
Valid paths must: 1) End with .md or .markdown, 2) Use forward slashes (e.g., 'folder/note.md'), 
3) Not contain '..' or start with '/', 4) Not exceed 255 characters. 
Example: 'Daily/2024-01-15.md' or 'Projects/My Project.md'

Empty Search Query:

Search query cannot be empty. 
Valid queries: 1) Keywords: 'machine learning', 
2) Tags: 'tag:#project', 3) Paths: 'path:Daily/', 
4) Combined: 'tag:#urgent TODO'

Invalid Date Parameters:

Invalid date_type: 'invalid'. 
Must be either 'created' or 'modified'. 
Use 'created' to find notes by creation date, 'modified' for last edit date

Troubleshooting

"Vault not found" error

  • Ensure the OBSIDIAN_VAULT_PATH environment variable is set correctly

  • Verify the path points to an existing Obsidian vault directory

  • Check that you have read/write permissions for the vault directory

Tags not showing up

  • Ensure tags are properly formatted (with or without # prefix)

  • Tags in frontmatter should be in YAML array format: tags: [tag1, tag2]

  • Inline tags should use the # prefix: #project #urgent

  • Tags inside code blocks are automatically excluded

"File too large" error

  • The server has a 10MB limit for note files and 50MB for images

  • This prevents memory issues with very large files

  • Consider splitting large notes into smaller ones

"Module not found" error

  • Ensure your virtual environment is activated

  • Run from the project root: python -m obsidian_mcp.server

  • Verify all dependencies are installed: pip install -r requirements.txt

Empty results when listing notes

  • Specify a directory when using list_notes (e.g., "Daily", "Projects")

  • Root directory listing requires recursive implementation

  • Check if notes are in subdirectories

Tags not updating

  • Ensure notes have YAML frontmatter section for frontmatter tags

  • Frontmatter must include a tags: field (even if empty)

  • The server now properly reads both frontmatter tags and inline hashtags

Best Practices for AI Assistants

Preventing Data Loss

  1. Always read before updating: The update_note tool REPLACES content by default

  2. Use append mode for additions: When adding to existing notes, use merge_strategy="append"

  3. Check note existence: Use read_note to verify a note exists before modifying

  4. Be explicit about overwrites: Only use overwrite=true when intentionally replacing content

Safe note editing:

  1. Read the existing note first

  2. Modify the content as needed

  3. Update with the complete new content

Adding to daily notes:

  • Use merge_strategy="append" to add entries without losing existing content

  • Use edit_note_section to add content to specific sections (like "## Tasks" or "## Notes")

Creating new notes:

  • Use create_note with overwrite=false (default) to prevent accidental overwrites

  • Add relevant tags to maintain organization

  • Use list_tags to see existing tags and avoid creating duplicates

Organizing with tags:

  • Check existing tags with list_tags before creating new ones

  • Maintain consistent naming (e.g., use "project" not "projects")

  • Use tags to enable powerful search and filtering

Security Considerations

  • Vault path access - The server only accesses the specified vault directory

  • The server validates all paths to prevent directory traversal attacks

  • File operations are restricted to the vault directory

  • Large files are rejected to prevent memory exhaustion

  • Path validation prevents access to system files

Development

Code Style

  • Uses FastMCP framework for MCP implementation

  • Pydantic models for type safety and validation

  • Modular architecture with separated concerns

  • Comprehensive error handling and user-friendly messages

Adding New Tools

  1. Create tool function in appropriate module under src/tools/

  2. Add Pydantic models if needed in src/models/

  3. Register the tool in src/server.py with the @mcp.tool() decorator

  4. Include comprehensive docstrings

  5. Add tests in tests/

  6. Test with MCP Inspector before deploying

Publishing (for maintainers)

To publish a new version to PyPI:

# 1. Update version in pyproject.toml
# 2. Clean old builds
rm -rf dist/ build/ *.egg-info/

# 3. Build the package
python -m build

# 4. Check the package
twine check dist/*

# 5. Upload to PyPI
twine upload dist/* -u __token__ -p $PYPI_API_KEY

# 6. Create and push git tag
git tag -a v2.0.2 -m "Release version 2.0.2"
git push origin v2.0.2

Users can then install and run with:

# Using uvx (recommended - no installation needed)
uvx obsidian-mcp

# Or install globally with pipx
pipx install obsidian-mcp
obsidian-mcp

# Or with pip
pip install obsidian-mcp
obsidian-mcp

Configuration

Performance and Indexing

The server now includes a persistent search index using SQLite for dramatically improved performance:

Key Features:

  • Instant startup - No need to rebuild index on every server start

  • Incremental updates - Only re-indexes files that have changed

  • 60x faster searches - SQLite queries are much faster than scanning all files

  • Lower memory usage - Files are loaded on-demand rather than all at once

Configuration Options:

Set these environment variables to customize behavior:

# Set logging level (default: INFO, options: DEBUG, INFO, WARNING, ERROR)
export OBSIDIAN_LOG_LEVEL=DEBUG

The search index is stored in your vault at .obsidian/mcp-search-index.db.

Performance Notes

  • Search indexing - With persistent index, only changed files are re-indexed

  • Concurrent operations - File operations use async I/O for better performance

  • Large vaults - Incremental indexing makes large vaults (10,000+ notes) usable

  • Image handling - Images are automatically resized to prevent memory issues

Migration from REST API Version

If you were using a previous version that required the Local REST API plugin:

  1. You no longer need the Obsidian Local REST API plugin - This server now uses direct filesystem access

  2. Replace OBSIDIAN_REST_API_KEY with OBSIDIAN_VAULT_PATH in your configuration

  3. Remove any OBSIDIAN_API_URL settings

  4. The new version is significantly faster and more reliable

  5. All features work offline without requiring Obsidian to be running

TDQS

A4.6/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full burden of behavioral disclosure. It effectively describes key behaviors: tags are added to frontmatter (not content), hierarchical structures are supported, duplicates are automatically prevented, and it returns the updated tag list. However, it doesn't mention error conditions, permission requirements, or rate limits.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is well-structured with clear sections (purpose, when to use, tag format, when not to use, returns) and every sentence adds value. There's no redundant information, and the most important information (what the tool does) is presented first.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a mutation tool with no annotations and no output schema, the description does an excellent job covering purpose, usage guidelines, parameter semantics, and behavioral traits. The main gap is the lack of explicit error handling information or permission requirements, which would be helpful for a tool that modifies notes.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

With 67% schema description coverage (2 of 3 parameters documented in schema), the description adds valuable context about tag format (simple vs. hierarchical) and the automatic handling of duplicates. While it doesn't explicitly discuss the 'path' parameter or the optional 'ctx' parameter, it provides meaningful semantic information about the core 'tags' parameter beyond what the schema offers.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the specific action ('Add tags') and target ('to a note's frontmatter'), distinguishing it from sibling tools like update_note (for content) and update_tags (for replacement). It provides a precise verb+resource combination that leaves no ambiguity about the tool's function.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description includes explicit 'When to use' and 'When NOT to use' sections with clear alternatives named (update_note for content tagging, update_tags with merge=False for replacement). This provides comprehensive guidance on when to select this tool versus other available options.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

batch_update_properties_toolA

Batch update properties across multiple notes.

When to use:

  • Updating metadata across many notes (status, priority, etc.)

  • Bulk tag operations (add/remove tags from multiple notes)

  • Archiving projects (set archived=true, add year property)

  • Cleaning up properties (remove outdated fields)

  • Normalizing metadata across your vault

Search criteria options:

  • query: Use search syntax (tag:project, folder:Archive, property:status:active)

  • folder: Process all notes in a folder (with optional recursive flag)

  • files: Explicit list of file paths

Property operations:

  • Add/update any frontmatter property

  • Remove properties by name

  • Special handling for tags (add/remove with deduplication)

  • Remove inline #tags from note body (optional)

Examples:

  • Archive completed projects: query="tag:project status:completed", property_updates={"archived": true, "year": 2024}

  • Clean up draft tags: query="tag:draft", remove_tags=["draft"], remove_inline_tags=true

  • Update all notes in folder: folder="Projects/2023", property_updates={"year": 2023}

When NOT to use:

  • Single note updates (use update_note, add_tags, etc.)

  • Complex content changes (this only updates frontmatter)

Returns: { "total_notes": 10, # Total notes found matching criteria "updated": 8, # Successfully updated notes "failed": 2, # Failed updates "details": [...], # List of changes per note "errors": [...] # List of errors with paths and reasons }

ParametersJSON Schema
NameRequiredDescriptionDefault
search_criteriaYesHow to find notes to update. Must include one of: 'query' (search string), 'folder' (folder path), or 'files' (list of paths). Use 'query' for complex searches, 'folder' for directory operations, 'files' for specific notes.
property_updatesNo
properties_to_removeNo
add_tagsNo
remove_tagsNo
remove_inline_tagsNoAlso remove tags from note body (inline #tags). Only applies when remove_tags is specified.
ctxNo

TDQS

A4.6/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full burden. It discloses key behavioral traits: it's a mutation tool (implied by 'update'), handles bulk operations, supports specific search criteria, manages frontmatter and tags with deduplication, and includes error handling (shown in the return structure). However, it doesn't mention permissions, rate limits, or irreversible changes, leaving some gaps.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is well-structured with clear sections (purpose, usage guidelines, search criteria, property operations, examples, exclusions, returns) and every sentence adds value. It's front-loaded with the core purpose and efficiently uses bullet points and examples without redundancy.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's complexity (7 parameters, mutation operations, no annotations, no output schema), the description is largely complete. It covers purpose, usage, parameters, and return values in detail. However, it lacks explicit mention of behavioral risks (e.g., data loss potential) and doesn't explain the 'ctx' parameter, leaving minor gaps.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is low (29%), but the description compensates well by explaining parameter semantics in 'Search criteria options' and 'Property operations' sections. It clarifies the purpose of 'search_criteria', 'property_updates', 'add_tags', 'remove_tags', and 'remove_inline_tags', though it doesn't cover all 7 parameters (e.g., 'ctx' is unexplained).

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's purpose with specific verbs ('batch update properties across multiple notes') and distinguishes it from sibling tools like 'update_note_tool' for single-note updates. It explicitly names the resource (notes) and scope (batch operations).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides explicit 'When to use' scenarios with concrete examples (e.g., archiving projects, bulk tag operations) and a 'When NOT to use' section that names specific alternatives ('use update_note, add_tags, etc.'). This clearly guides the agent on when to choose this tool over siblings.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

create_folder_toolA

Create a new folder in the vault, including all parent folders in the path.

When to use:

  • Setting up project structure in advance

  • Creating deep folder hierarchies (e.g., "Research/Studies/2024")

  • Creating archive folders before moving notes

  • Establishing organizational hierarchy

  • Preparing folders for future content

When NOT to use:

  • If you're about to create a note in that path (folders are created automatically)

  • For temporary organization (just create notes directly)

Note: Will create all necessary parent folders. For example, "Research/Studies/2024" will create Research, Research/Studies, and Research/Studies/2024 if they don't exist.

Returns: Creation status with list of folders created and placeholder file path

ParametersJSON Schema
NameRequiredDescriptionDefault
folder_pathYesPath of the folder to create
create_placeholderNoWhether to create a placeholder file (.gitkeep or README.md)
ctxNo

TDQS

A4.6/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries full burden and does well by disclosing key behaviors: it creates all necessary parent folders (with a concrete example), mentions placeholder file creation, and describes the return format. It doesn't cover potential errors, permissions, or rate limits, but provides substantial operational context.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is efficiently structured with clear sections (purpose, usage guidelines, note, returns), each sentence adds value, and it's appropriately sized for a tool with behavioral complexity. No wasted words while maintaining completeness.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a mutation tool with no annotations and no output schema, the description provides good coverage: clear purpose, usage guidelines, behavioral details, and return format description. It could mention error conditions or permissions, but addresses most critical aspects given the context.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

With 67% schema description coverage (2 of 3 parameters documented), the description adds meaningful context beyond the schema. It explains the parent-folder creation behavior for 'folder_path' and mentions placeholder files which relates to 'create_placeholder', though it doesn't address the undocumented 'ctx' parameter. This compensates well for the coverage gap.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the specific action ('Create a new folder in the vault') and resource ('folder'), including the key behavioral trait of creating parent folders. It distinguishes from sibling tools like 'create_note_tool' by focusing exclusively on folder creation rather than note creation.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides explicit 'When to use' and 'When NOT to use' sections with concrete scenarios, including a direct alternative ('create notes directly') and a specific sibling tool scenario ('folders are created automatically' with create_note_tool). This gives clear guidance on tool selection.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

create_note_toolA

Create a new note or overwrite an existing one.

When to use:

  • Creating new notes with specific content

  • Setting up templates or structured notes

  • Programmatically generating documentation

When NOT to use:

  • Updating existing notes (use update_note unless you want to replace entirely)

  • Appending content (use update_note with merge_strategy="append")

Returns: Created note information with path and metadata

ParametersJSON Schema
NameRequiredDescriptionDefault
pathYesWhere to create the new note in your vault. Folders will be created automatically if needed.
contentYesThe markdown content for your note. Can include headings (#), tags (#tag), links ([[other note]]), and frontmatter.
overwriteNoSet to true to replace an existing note at this location. Use carefully as this deletes the original content.
ctxNo

TDQS

A4.6/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries full burden and does well by disclosing key behavioral traits: it can overwrite/delete existing content (destructive potential), mentions 'use carefully' for overwrite parameter, and describes the return format ('Created note information with path and metadata'). It doesn't cover rate limits or authentication needs, but provides solid operational context.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is perfectly structured with clear sections (purpose, when to use, when not to use, returns), front-loads the core functionality, and every sentence adds value. No wasted words while maintaining completeness.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a mutation tool with no annotations and no output schema, the description provides excellent context about behavior, usage boundaries, and return values. It covers the destructive potential of overwrite and distinguishes from alternatives. The main gap is lack of explicit error handling or permission requirements, but otherwise quite complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

With 75% schema description coverage, the description adds meaningful context beyond the schema. While it doesn't detail individual parameters, it explains the tool's overall behavior with parameters (creating/overwriting notes, setting up templates) that helps understand how parameters work together. The 'Returns' section also provides output context not in the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's purpose with specific verbs ('create' and 'overwrite') and resource ('note'), distinguishing it from siblings like update_note_tool. It explicitly mentions both creation and replacement functionality, which is more specific than just 'create'.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides explicit 'When to use' and 'When NOT to use' sections with clear alternatives named (update_note with specific strategies). It distinguishes this tool from update_note_tool for complete replacements versus partial updates.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

delete_note_toolA

Delete a note from the vault permanently.

When to use:

  • Removing outdated or duplicate notes

  • Cleaning up temporary drafts

  • Part of a move operation (delete after successful copy)

When NOT to use:

  • Archiving (use move_note to Archive folder instead)

  • Temporary removal (no undo available)

āš ļø WARNING: This operation cannot be undone. The note will be permanently deleted.

Returns: Deletion confirmation with the path of the deleted note

ParametersJSON Schema
NameRequiredDescriptionDefault
pathYesPath to the note to delete from your vault
ctxNo

TDQS

A4.4/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries full burden and does well by disclosing critical behavioral traits: it's a destructive operation ('permanently deleted'), has no undo capability, and includes a warning about irreversibility. It also mentions the return format (confirmation with path), though it could elaborate on error cases or permissions.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is well-structured with clear sections (purpose, usage guidelines, warnings, returns), front-loaded with the core action, and every sentence adds value without redundancy. It's appropriately sized for a destructive tool needing careful explanation.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a destructive tool with no annotations and no output schema, the description does a good job covering purpose, usage, warnings, and return values. It could be more complete by detailing error scenarios (e.g., what happens if the path doesn't exist) or auth requirements, but it's largely sufficient given the context.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 50% (only 'path' has a description, 'ctx' is undocumented). The description doesn't add parameter-specific details beyond what's in the schema for 'path', and doesn't explain the 'ctx' parameter at all. Baseline 3 is appropriate as the schema covers half the parameters adequately.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the specific action ('Delete a note from the vault permanently') with the resource ('note'), distinguishing it from siblings like move_note_tool or archive operations. It explicitly mentions permanent deletion, which differentiates it from temporary removal or archiving tools.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides explicit 'When to use' scenarios (removing outdated notes, cleaning drafts, move operations) and 'When NOT to use' guidance (archiving, temporary removal), including a named alternative (move_note to Archive folder). This gives clear context for when to choose this tool over siblings.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

edit_note_section_toolA

Edit a specific section of a note identified by a markdown heading.

When to use:

  • Adding content to a specific section without rewriting the whole note

  • Updating a particular section (like status updates, task lists)

  • Inserting content at precise locations in structured notes

  • Building up notes incrementally by section

When NOT to use:

  • Simple append to end of note (use update_note with merge_strategy='append')

  • Replacing entire note content (use update_note)

  • Creating a new note (use create_note)

Section identification:

  • Sections are identified by markdown headings (# ## ### etc.)

  • Match is case-insensitive

  • First matching heading is used if duplicates exist

  • Section includes content until next heading of same/higher level

Operations:

  • insert_after: Add content immediately after the section heading

  • insert_before: Add content immediately before the section heading

  • replace: Replace entire section including the heading

  • append_to_section: Add content at the end of the section

Returns: Edit status including whether section was found or created

ParametersJSON Schema
NameRequiredDescriptionDefault
pathYesPath to the note to edit
section_identifierYesMarkdown heading that identifies the section (e.g., '## Tasks', '### Status')
contentYesContent to insert, replace, or append to the section
operationNoHow to edit the section. 'insert_after' = add content after heading, 'insert_before' = add before heading, 'replace' = replace entire section, 'append_to_section' = add to end of sectioninsert_after
create_if_missingNoCreate the section at the end of the note if it doesn't exist
ctxNo

TDQS

A4.6/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full burden of behavioral disclosure. It effectively describes key behaviors: section identification rules (case-insensitive, first match, content boundaries), operations (insert_after, insert_before, replace, append_to_section), and the create_if_missing option. However, it lacks details on error handling, permissions, or rate limits, which are relevant for a mutation tool. The description does not contradict any annotations, as none are present.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is well-structured with clear sections (purpose, usage guidelines, section identification, operations, returns), each sentence adds value, and it avoids redundancy. It is appropriately sized for a tool with 6 parameters and complex behavior, front-loading the core purpose and usage guidelines for quick comprehension.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's complexity (6 parameters, mutation operation, no annotations, no output schema), the description is largely complete: it covers purpose, usage, behavioral rules, and parameter semantics. However, it lacks output details (only mentions 'Edit status' vaguely) and doesn't address potential errors or side effects, which are important for a tool that modifies notes. This minor gap prevents a perfect score.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema description coverage is high (83%), so the baseline is 3. The description adds meaningful context beyond the schema: it explains how 'section_identifier' works with markdown headings and matching rules, clarifies the 'operation' options with practical examples, and mentions the 'create_if_missing' behavior. This compensates for the 17% coverage gap and provides valuable semantic understanding, though it doesn't detail all parameters (e.g., 'ctx' is unexplained).

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description starts with a clear, specific statement: 'Edit a specific section of a note identified by a markdown heading.' This explicitly states the verb ('edit'), resource ('specific section of a note'), and mechanism ('identified by a markdown heading'), distinguishing it from sibling tools like update_note_tool or create_note_tool. The purpose is unambiguous and well-articulated.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description includes explicit 'When to use' and 'When NOT to use' sections, listing four use cases and three exclusions with named alternatives (e.g., 'use update_note with merge_strategy='append''). This provides clear, actionable guidance on when to select this tool over its siblings, such as update_note_tool for whole-note edits or create_note_tool for new notes.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

find_orphaned_notes_toolA

Find orphaned notes that may need organization or cleanup.

When to use:

  • Regular vault maintenance and cleanup

  • Finding forgotten or disconnected notes

  • Identifying notes that need better organization

  • Preparing for vault reorganization

  • Finding candidates for archival or deletion

Orphan types explained:

  • no_backlinks: Notes with no incoming links (most common definition)

  • no_links: Notes with no incoming OR outgoing links (completely isolated)

  • no_tags: Notes without any tags (untagged content)

  • no_metadata: Notes with minimal/no frontmatter properties

  • isolated: Notes with no links AND no tags (truly disconnected)

Default exclusions:

  • Templates folder (usually contains reference notes)

  • Archive folder (already organized)

  • Daily folder (daily notes often standalone)

When NOT to use:

  • Finding specific notes (use search_notes)

  • Getting all notes in a folder (use list_notes)

  • Finding notes by content (use search tools)

Performance note:

  • Scans entire vault and checks links/metadata for each note

  • For vaults >1000 notes, this may take 10-30 seconds

Returns: List of orphaned notes with paths, reasons, and metadata. Results are sorted by modification date (oldest first).

Example response: { "count": 23, "orphaned_notes": [ { "path": "Random Thoughts/Old Idea.md", "reason": "No incoming links", "modified": "2023-06-15T10:30:00Z", "size": 245, "word_count": 42 } ], "stats": { "total_notes_scanned": 500, "excluded_folders": ["Templates", "Archive", "Daily"], "orphan_type": "no_backlinks" } }

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's complexity (4 parameters, no annotations, no output schema), the description is highly complete. It covers purpose, usage, parameters, behavior, performance, exclusions, and includes an example response, providing all necessary context for an agent to use it effectively.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is low (25%), but the description compensates by explaining 'orphan types' in detail (e.g., 'no_backlinks: Notes with no incoming links'), clarifying 'default exclusions' (e.g., 'Templates folder'), and mentioning 'min_age_days' context ('Helps exclude recent work-in-progress'). It adds meaningful context beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's purpose with specific verb ('Find') and resource ('orphaned notes'), and distinguishes it from siblings by explaining what makes notes 'orphaned' (e.g., 'no_backlinks', 'no_links'). It explicitly differentiates from tools like 'search_notes' and 'list_notes'.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides explicit guidance on when to use (e.g., 'Regular vault maintenance and cleanup', 'Finding forgotten or disconnected notes') and when NOT to use (e.g., 'Finding specific notes (use search_notes)', 'Getting all notes in a folder (use list_notes)'), including clear alternatives.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

get_note_info_toolA

TDQS

A4.6/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full burden of behavioral disclosure. It effectively communicates that this is a read-only operation ('without reading its content'), describes what information is returned, and clarifies it's for metadata/statistics only. However, it doesn't mention potential limitations like rate limits, authentication requirements, or error conditions.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is well-structured with clear sections (purpose, usage guidelines, returns) and every sentence adds value. It's front-loaded with the core purpose, followed by practical guidance, and concludes with return details. No wasted words or redundant information.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a tool with no annotations and no output schema, the description provides excellent context about what the tool does, when to use it, and what it returns. The 'Returns' section effectively documents the output structure. The main gap is the lack of explicit behavioral constraints (like rate limits or permissions), but overall it's quite complete for this complexity level.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema description coverage is 50% (only the 'path' parameter has a description), but the description compensates by providing context about what the 'path' parameter represents ('Path to the note to analyze') and includes examples in the schema. The 'ctx' parameter remains undocumented, but the description's overall clarity about the tool's purpose helps contextualize parameter usage.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's purpose with specific verbs ('get metadata and statistics') and resource ('about a note'), explicitly distinguishing it from sibling tools like read_note and search tools by emphasizing it doesn't read content. The first sentence provides a concise, accurate summary of the tool's function.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description includes explicit 'When to use' and 'When NOT to use' sections that provide clear guidance on appropriate contexts and name specific alternative tools (read_note, search tools, update tools). This gives the agent precise direction on when to select this tool versus its siblings.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

list_folders_toolA

List folders in the vault or a specific directory.

When to use:

  • Exploring vault organization structure

  • Verifying folder names before creating notes

  • Checking if a specific folder exists

  • Understanding the hierarchy of the vault

TDQS

A4.6/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full burden. It discloses behavioral traits: it's a read operation (implied by 'List'), returns folder structure with paths and names, and mentions optional directory parameter with default behavior. However, it doesn't specify pagination, rate limits, or error conditions, leaving some gaps.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is well-structured with clear sections (purpose, when to use, when not to use, returns). Every sentence adds value: the first states the core function, the bullet points provide practical guidance, and the returns section clarifies output. No wasted words.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a read-only tool with no output schema, the description is mostly complete: it covers purpose, usage guidelines, and output format. However, with no annotations and incomplete parameter documentation (missing 'ctx'), there are minor gaps in behavioral context and parameter understanding.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is only 33% (1 of 3 parameters described in schema). The description compensates by explaining the directory parameter's purpose ('specific directory to list folders from') and default behavior ('defaults to root'), and mentions recursive behavior in the schema. However, it doesn't address the 'ctx' parameter at all, which remains undocumented.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's purpose with specific verb ('List') and resource ('folders in the vault or a specific directory').

list_tags_toolA

List all unique tags used across the vault with usage statistics.

When to use:

  • Before adding tags to maintain consistency

  • Getting an overview of your tagging taxonomy

  • Finding underused or overused tags

  • Discovering tag variations (e.g., 'project' vs 'projects')

  • Understanding hierarchical tag structures in your vault

  • Finding all files that use a specific tag (with include_files=true)

Hierarchical tags:

  • Lists both parent and full hierarchical paths (e.g., both "project" and "project/web")

  • Shows how nested tags are organized in your vault

  • Helps identify opportunities for better tag organization

File paths (with include_files=true):

  • Returns a list of all file paths that contain each tag

  • Useful for bulk operations on files with specific tags

  • Paths are relative to vault root

When NOT to use:

  • Getting tags for a specific note (use get_note_info)

  • Searching notes by tag (use search_notes with tag: prefix)

Performance note:

  • For vaults with <1000 notes: Fast (1-3 seconds)

  • For vaults with 1000-5000 notes: Moderate (3-10 seconds)

  • For vaults with >5000 notes: May be slow (10+ seconds)

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's moderate complexity (4 parameters, no output schema, no annotations), the description provides excellent completeness. It covers purpose, usage guidelines, parameter implications, performance characteristics, hierarchical tag behavior, file path details, and return value information. This fully compensates for the lack of structured metadata.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 75% (3 of 4 parameters well-described). The description adds significant value beyond the schema by explaining the implications of include_files=true (returns file paths, useful for bulk operations, paths relative to vault root) and providing context about hierarchical tags. However, it doesn't fully explain the ctx parameter, which has no schema description.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's purpose: 'List all unique tags used across the vault with usage statistics.' It specifies the verb ('List'), resource ('unique tags'), and scope ('across the vault'), and distinguishes itself from siblings like get_note_info and search_notes by explicitly stating when not to use it. This provides excellent differentiation.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description includes explicit 'When to use' and 'When NOT to use' sections, naming specific alternatives (get_note_info, search_notes with tag: prefix). It also provides contextual guidance like 'Before adding tags to maintain consistency' and 'Finding all files that use a specific tag (with include_files=true)', giving comprehensive usage direction.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

move_folder_toolA

Move an entire folder and all its contents to a new location.

When to use:

  • Reorganizing vault structure

  • Archiving completed projects

  • Consolidating related notes

  • Seasonal organization (e.g., moving to year-based archives)

When NOT to use:

  • Moving individual notes (use move_note instead)

  • Moving to a subfolder of the source (creates circular reference)

Returns: Move status with count of notes and folders moved

ParametersJSON Schema
NameRequiredDescriptionDefault
source_folderYesCurrent folder path to move
destination_folderYesNew location for the folder
update_linksNoWhether to update links in other notes (future enhancement)
ctxNo

TDQS

A4.6/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full burden. It discloses key behavioral traits: it's a mutation operation (implied by 'move'), it handles bulk content ('all its contents'), and it returns status with counts. However, it lacks details on permissions, error conditions, or rate limits, which would be helpful for a destructive operation.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is well-structured with clear sections (purpose, usage guidelines, returns), uses bullet points for readability, and every sentence adds value without redundancy. It's appropriately sized for the tool's complexity and front-loaded with the core action.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's moderate complexity (4 parameters, no output schema, no annotations), the description is largely complete: it covers purpose, usage, and return values. However, it could better address potential pitfalls (e.g., what happens if the destination exists) and the unexplained 'ctx' parameter, leaving minor gaps.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 75%, so the schema documents most parameters well. The description adds value by implicitly clarifying that 'source_folder' and 'destination_folder' refer to paths for moving operations, and it hints at the 'update_links' parameter's purpose ('future enhancement'). It doesn't fully compensate for the 25% gap (e.g., 'ctx' is unexplained), but provides useful context beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the specific action ('Move an entire folder and all its contents') and resource ('folder'), distinguishing it from sibling tools like 'move_note' which handles individual notes. The verb 'move' is precise and the scope 'entire folder and all its contents' is explicit.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides explicit 'When to use' scenarios (e.g., reorganizing vault structure, archiving projects) and 'When NOT to use' cases (e.g., moving individual notes, creating circular references), including a named alternative ('move_note'). This gives clear guidance on tool selection versus siblings.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

move_note_toolA

Move a note to a new location, optionally with a new name.

When to use:

  • Reorganizing notes into different folders

  • Moving AND renaming in one operation

  • Archiving completed projects

  • Consolidating scattered notes

When NOT to use:

  • Just renaming within same folder (use rename_note for clarity)

  • Copying notes (use read_note + create_note instead)

  • Moving entire folders (use move_folder)

Link updating:

  • Automatically detects if filename changes during move

  • Updates all [[wiki-style links]] only when name changes

  • Preserves link aliases and formatting

  • No updates needed for simple folder moves (links work by name)

Returns: Move confirmation with path changes and link update details

ParametersJSON Schema
NameRequiredDescriptionDefault
source_pathYesCurrent location of the note to move
destination_pathYesNew location for the note. Folders will be created if needed.
update_linksNoAutomatically update all [[wiki links]] if the filename changes during move
ctxNo

Given the tool's complexity (mutation with link updating), no annotations, and no output schema, the description provides comprehensive context. It covers purpose, usage guidelines, behavioral details, parameter semantics, and return information, making it complete enough for an agent to understand and use the tool effectively.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

With 75% schema description coverage, the description adds meaningful context beyond the schema. It explains the link updating behavior tied to the 'update_links' parameter and clarifies that 'destination_path' creates folders if needed. The 'ctx' parameter remains undocumented, but the description compensates well for the schema's partial coverage.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's purpose with specific verbs ('move', 'rename') and resource ('note'), and distinguishes it from sibling tools like rename_note, create_note, and move_folder. The opening sentence 'Move a note to a new location, optionally with a new name' is precise and actionable.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides explicit 'When to use' and 'When NOT to use' sections with clear alternatives named (rename_note, read_note + create_note, move_folder). This gives comprehensive guidance on when to select this tool versus other available options.

When to use:

  • Analyzing specific image files from the vault

  • Examining standalone images (not embedded in notes)

  • Processing images for detailed analysis

When NOT to use:

  • Getting images embedded in notes (use view_note_images instead)

  • Searching for images (use list_notes with appropriate filters)

Returns: Image object that Claude can analyze and describe

ParametersJSON Schema
NameRequiredDescriptionDefault
pathYesPath to the image file relative to vault root
include_metadataNoInclude file size and other metadata about the image
ctxNo

TDQS

A4.6/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full burden of behavioral disclosure. It effectively explains what the tool does (reads image files for analysis), what it returns (Image object that Claude can analyze), and distinguishes it from related operations. However, it doesn't mention potential limitations like file size constraints, supported formats beyond what's in the schema pattern, or error conditions.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is well-structured with clear sections (purpose, when to use, when not to use, returns) and every sentence adds value. It's front-loaded with the core purpose and efficiently organized without wasted words. The bullet-point format enhances readability while maintaining conciseness.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a read operation with no annotations and no output schema, the description provides good context about what the tool does, when to use it, and what it returns. It covers the essential aspects well, though it could benefit from mentioning potential error cases or limitations. Given the straightforward nature of an image reading tool, the description is largely complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 67% (2 of 3 parameters have descriptions). The description doesn't explicitly discuss parameters, but the 'path' parameter's purpose is implied through the tool's overall purpose. The 'include_metadata' and 'ctx' parameters aren't mentioned, but with moderate schema coverage and the tool's straightforward purpose, the description provides sufficient context for understanding the primary parameter's role.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's purpose with specific verb ('Read') and resource ('image file from the Obsidian vault'), and distinguishes it from sibling tools by specifying it's for standalone images rather than embedded ones. The opening sentence 'Read an image file from the Obsidian vault for analysis' provides immediate clarity about the tool's function.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides explicit 'When to use' and 'When NOT to use' sections with clear alternatives named (view_note_images and list_notes). It gives specific scenarios for appropriate use (analyzing specific image files, examining standalone images) and explicitly contrasts with sibling tools for different use cases.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

read_note_toolA

Read the content and metadata of a specific note.

When to use:

  • Displaying note contents to the user

  • Analyzing or processing existing note data

  • ALWAYS before updating a note to preserve existing content

  • Verifying a note exists before making changes

When NOT to use:

  • Searching multiple notes (use search_notes instead)

  • Getting only metadata (use get_note_info for efficiency)

  • Viewing images in a note (use view_note_images instead)

Returns: Note content and metadata including tags, aliases, and frontmatter. Image references (alt) are preserved in the content but images are not loaded.

IMPORTANT: If the note contains image references, proactively offer to analyze them: "I can see this note contains [N] images. Would you like me to analyze/examine them for you?" Then use view_note_images to load and analyze the images if requested.

ParametersJSON Schema
NameRequiredDescriptionDefault
pathYesNote location within your vault (e.g., 'Projects/AI Research.md'). Use forward slashes for folders.
ctxNo

A4.6/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full burden of behavioral disclosure. It effectively describes the tool's behavior: it's a read operation (implied by 'Read'), returns content and metadata with specific details (tags, aliases, frontmatter), preserves image references without loading them, and includes proactive user interaction guidance for handling images. It covers key aspects like output format and user interaction patterns, though it doesn't mention error handling or permissions.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is well-structured with clear sections ('When to use,' 'When NOT to use,' 'Returns,' 'IMPORTANT'), making it easy to scan. It is appropriately sized for the tool's complexity, with each sentence adding value (e.g., usage scenarios, output details, user interaction advice). However, the 'IMPORTANT' section is somewhat verbose and could be more concise.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's moderate complexity (2 parameters, no output schema, no annotations), the description is highly complete. It covers purpose, usage guidelines, behavioral details (including output format and image handling), and proactive user interaction. It effectively compensates for the lack of annotations and output schema, providing all necessary context for an AI agent to use the tool correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 50% (only 'path' has a description, 'ctx' does not). The description adds no explicit parameter information beyond what's in the schema, but it implicitly clarifies the tool's focus on a single note via 'specific note,' which aligns with the 'path' parameter. Since there are only 2 parameters and the schema covers the critical 'path' parameter well, the description compensates adequately without redundancy, though it doesn't address the undocumented 'ctx' parameter.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's purpose as 'Read the content and metadata of a specific note,' which is a specific verb+resource combination. It distinguishes from siblings like 'search_notes' (for multiple notes), 'get_note_info' (for metadata only), and 'view_note_images' (for images), providing clear differentiation.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description includes explicit 'When to use' and 'When NOT to use' sections with specific scenarios and named alternatives. It provides clear guidance on when to use this tool versus siblings like 'search_notes,' 'get_note_info,' and 'view_note_images,' including efficiency considerations and workflow advice (e.g., 'ALWAYS before updating a note').

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

remove_tags_toolA

Remove specific tags from a note's frontmatter.

When to use:

  • Cleaning up outdated tags

  • Removing temporary tags (like 'draft' or 'review')

  • Tag maintenance and reorganization

  • After completing tagged tasks

When NOT to use:

  • Removing all tags (use update_tags with empty list)

  • Replacing tags (use update_tags with merge=False)

Note: Only removes exact matches. To remove all subtags of a hierarchical tag, list them explicitly or use update_tags.

Returns: Updated tag list after removal, with count of removed tags

ParametersJSON Schema
NameRequiredDescriptionDefault
pathYesPath to the note
tagsYesTags to remove from the note (without # prefix). Removes exact matches only.
ctxNo

TDQS

A4.6/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries full burden and does well by disclosing key behavioral traits: it specifies 'Only removes exact matches' (important constraint), explains hierarchical tag handling, and describes the return value (updated tag list with count). However, it doesn't mention potential errors (e.g., if note doesn't exist) or permission requirements.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

For a mutation tool with no annotations and no output schema, the description provides good coverage: clear purpose, usage guidelines, behavioral constraints, and return value description. It could be more complete by addressing error cases or permission requirements, but it covers the essential context well given the complexity.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

With 67% schema description coverage (2 of 3 parameters documented in schema), the description adds meaningful context: it clarifies that tags should be provided 'without # prefix' and that removal is 'exact matches only', which complements the schema's tag description. The 'ctx' parameter remains undocumented in both schema and description, but the description provides good coverage for the core parameters.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the specific action ('Remove specific tags from a note's frontmatter') and distinguishes it from sibling tools like 'update_tags_tool' and 'add_tags_tool'. It specifies the exact resource (tags in note frontmatter) and scope (exact matches only).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides explicit 'When to use' scenarios (cleaning up outdated tags, removing temporary tags, etc.) and 'When NOT to use' guidance with named alternatives (use update_tags for removing all tags or replacing tags). It clearly differentiates this tool from sibling update_tags_tool.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the complexity (a mutation tool with 4 parameters, no annotations, and no output schema), the description is mostly complete. It covers purpose, usage, behavioral traits, and return details. However, it lacks explicit error handling or permission requirements, which are important for a tool that modifies data, leaving a minor gap in completeness.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 75%, so the schema already documents most parameters well. The description adds meaningful context beyond the schema by explaining the purpose of parameters implicitly (e.g., 'Automatically updates all [[wiki-style links]]' relates to update_links) and clarifying constraints like 'must be in same directory' for new_path. This compensates well for the 25% coverage gap.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's purpose with a specific verb ('Rename') and resource ('a note'), and explicitly distinguishes it from sibling tools by mentioning what it does not do (e.g., 'Moving notes to different folders (use move_note)'). This provides clear differentiation from alternatives like move_note or create_note.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description includes explicit 'When to use' and 'When NOT to use' sections with concrete examples (e.g., 'Changing a note's title', 'Fixing typos') and named alternatives (e.g., 'use move_note', 'use read_note + create_note'). This gives comprehensive guidance on when to select this tool over others.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

search_by_date_toolA

The description is well-structured with clear sections (purpose, usage guidelines, returns), front-loaded with the core purpose, and every sentence adds value without redundancy. It efficiently communicates essential information in a compact format.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's moderate complexity (4 parameters, no output schema, no annotations), the description provides good contextual completeness. It covers purpose, usage guidelines, and return values, which is sufficient for a search tool. However, without an output schema, it could benefit from more detail on the return structure (e.g., format of 'paths and timestamps').

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema description coverage is 75%, with three parameters well-documented (date_type, days_ago, operator) and one (ctx) lacking description. The tool description doesn't add parameter details beyond the schema, but since coverage is high and the undocumented 'ctx' parameter appears to be a common context parameter (implied by its name and null default), the description is adequate. A baseline of 3 is adjusted upward due to the high schema coverage compensating for the description's lack of parameter elaboration.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's purpose as 'Search for notes by creation or modification date,' which is a specific verb+resource combination. It distinguishes itself from sibling tools like 'search_notes' (for content-based search) and 'search_by_property_tool' or 'search_by_regex_tool' by focusing exclusively on date-based filtering.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description includes explicit 'When to use' and 'When NOT to use' sections, providing clear guidance on appropriate scenarios (e.g., finding recently modified notes) and alternatives (e.g., using 'search_notes' for content-based search). This directly addresses sibling tool differentiation and usage context.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

search_by_property_toolA

Search for notes by their frontmatter property values.

When to use:

  • Finding notes with specific metadata (status, priority, etc.)

  • Filtering by numeric properties (rating > 4, priority <= 2)

  • Filtering by date properties (deadline < "2024-12-31")

  • Searching within array/list properties (tags, aliases, categories)

  • Checking which notes have certain properties defined

  • Building database-like queries on your notes

Property types supported:

  • Text/String: Exact match or contains

  • Numbers: Comparison operators work numerically

  • Dates: ISO format (YYYY-MM-DD) with intelligent comparison

  • Arrays/Lists: Searches within list items, comparisons use list length

  • Legacy properties: Automatically handles tag→tags, alias→aliases migrations

When NOT to use:

  • Content search (use search_notes instead)

  • Tag search (use search_notes with tag: prefix)

  • Path/filename search (use search_notes with path: prefix)

Examples:

  • Find active projects: property_name="status", value="active"

  • Find high priority: property_name="priority", operator=">", value="2"

  • Find notes with deadlines: property_name="deadline", operator="exists"

  • Find notes by author: property_name="author", operator="contains", value="john"

A4.6/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full burden. It effectively discloses key behavioral traits: it's a read-only search tool (implied by 'search'), supports various property types and operators, handles legacy migrations, and returns notes with values displayed. However, it lacks details on rate limits, error handling, or pagination, preventing a perfect score.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is well-structured with clear sections (purpose, when to use, property types, when not to use, examples, returns), each sentence adds value without redundancy. It's appropriately sized for a complex tool with 5 parameters and no annotations, making it easy to scan and understand.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's complexity (5 parameters, 60% schema coverage, no annotations, no output schema), the description is largely complete. It covers purpose, usage, parameters, and return behavior. However, it lacks explicit output details (e.g., format, pagination) and full parameter documentation (e.g., ctx), leaving minor gaps.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 60%, and the description compensates well by explaining parameter semantics beyond the schema. It clarifies that property_name refers to 'frontmatter property values' and provides examples of usage for property_name, value, and operator (e.g., 'exists' checks presence). However, it doesn't fully address context_length or ctx, leaving some gaps.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's purpose: 'Search for notes by their frontmatter property values.' It specifies the verb ('search'), resource ('notes'), and scope ('frontmatter property values'), distinguishing it from siblings like search_notes_tool (content search) and search_by_date_tool (date-specific).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description explicitly provides 'When to use' with six specific scenarios (e.g., filtering by metadata, numeric properties, dates) and 'When NOT to use' with three clear exclusions (content search, tag search, path search), naming alternatives like search_notes. This comprehensive guidance helps the agent choose correctly among siblings.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

search_by_regex_toolA

Search for notes using regular expressions for advanced pattern matching.

When to use:

  • Finding complex patterns (URLs, code syntax, structured data)

  • Searching with wildcards and special characters

  • Case-sensitive or multi-line pattern matching

  • Finding TODO/FIXME comments with context

When NOT to use:

  • Simple text search (use search_notes instead)

  • Searching by tags or properties (use dedicated tools)

Common patterns:

  • URLs: r"https?://[^\s]+"

  • Email: r"[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+.[a-zA-Z]{2,}"

  • TODO comments: r"(TODO|FIXME)\s*:.*"

  • Markdown headers: r"^#{1,6}\s+.*"

  • Code blocks: r"\w*\n[\s\S]*?"

Returns: Notes containing regex matches with match details and context

ParametersJSON Schema
NameRequiredDescriptionDefault
patternYesRegular expression pattern for advanced searches. Use for finding URLs, code patterns, TODO items, etc.
flagsNo
context_lengthNoCharacters to show around matches
max_resultsNoMaximum number of notes to return. Use smaller values for faster responses.
ctxNo

TDQS

A4.6/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the full burden. It discloses key behavioral traits: the tool returns 'Notes containing regex matches with match details and context,' and the 'Common patterns' section implies it supports complex regex features. However, it doesn't mention performance considerations like speed or resource usage, which could be relevant for a regex search tool.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is well-structured with clear sections (purpose, usage guidelines, patterns, returns), front-loaded key information, and every sentence adds value (e.g., specific examples, explicit alternatives). It's appropriately sized for a tool with 5 parameters and no annotations.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's complexity (regex-based search, 5 parameters, no annotations, no output schema), the description is mostly complete: it covers purpose, usage, parameters via examples, and output behavior. However, it lacks details on error handling, performance implications (e.g., regex complexity impact), or the 'ctx' parameter's purpose, leaving minor gaps.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 60%, so the description must compensate. It adds significant value: the 'Common patterns' section provides concrete regex examples (e.g., for URLs, emails, TODO comments) that clarify the 'pattern' parameter beyond the schema's examples, and the 'Returns' section explains output semantics. However, it doesn't detail all parameters like 'ctx' or fully explain 'flags' beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's purpose: 'Search for notes using regular expressions for advanced pattern matching.' It specifies the verb ('search'), resource ('notes'), and method ('regular expressions'), distinguishing it from sibling tools like 'search_notes_tool' for simple text search and 'search_by_property_tool' for property-based searches.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides explicit guidance with 'When to use' and 'When NOT to use' sections, listing specific scenarios (e.g., finding complex patterns, URLs, TODO comments) and naming alternatives ('use search_notes instead' for simple text search, 'use dedicated tools' for tags/properties). This clearly differentiates it from sibling tools.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

search_notes_toolA

Search for notes by filename or content, with smart ranking.

DEFAULT BEHAVIOR (NEW): Searches BOTH note filenames AND content automatically. Filename matches are ranked higher than content matches for better discovery.

When to use:

  • Finding a note when you know part of its name (just type the name)

  • Finding notes containing specific content

  • Locating notes with specific tags

  • Searching within specific folders

  • Finding notes by frontmatter properties

Search modes:

  • Default: searches BOTH filenames and content (filename matches ranked higher) Example: "tag refactor" finds "Obsidian Tag Refactor.md" AND notes mentioning "tag refactor"

  • "path:text" - searches ONLY in filenames/paths

  • "tag:tagname" - searches by tag (supports hierarchical tags)

  • "property:name:value" - searches by frontmatter properties

Examples:

  • Find a note by name: "Project Tracker" (will find "Project Tracker.md" first)

  • Search content only: Use explicit path: prefix to exclude: "path:Project"

  • Find by tag: "tag:important" or "tag:project/web"

  • Find by property: "property:status:active"

Tag search supports hierarchical tags:

  • "tag:project" finds all project-related tags including project/web, project/mobile

  • "tag:web" finds any tag ending with "web" like project/web, design/web

When NOT to use:

  • Searching by date (use search_by_date instead)

  • Listing all notes (use list_notes for better performance)

  • Reading a specific note when you know the exact path (use read_note directly)

Returns: Search results with matched notes, relevance scores, and context. Filename matches have higher scores than content matches. Response includes match_type field: "filename" or "content".

ParametersJSON Schema
NameRequiredDescriptionDefault
queryYesSearch query that matches BOTH filenames and content by default. Just type a note name to find it! Use prefixes for specific search types: 'tag:' for tags, 'path:' for ONLY filenames, 'property:' for metadata.
context_lengthNoHow much text to show around each match for context. Higher values show more surrounding content.
max_resultsNoMaximum number of results to return. Use smaller values for faster responses and larger values for comprehensive searches.
ctxNo

TDQS

A4.6/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full burden of behavioral disclosure. It effectively describes key behaviors: default search mode (both filenames and content), ranking logic (filename matches ranked higher), search modes with prefixes, hierarchical tag support, and return format (results with scores, match_type). It doesn't mention performance characteristics like rate limits or authentication needs, but covers most operational aspects well.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is well-structured with clear sections (default behavior, when to use, search modes, examples, when not to use, returns) and uses bullet points for readability. While comprehensive, some sections could be more concise (e.g., the examples are detailed but necessary). Every sentence adds value, but the overall length is substantial though justified by the tool's complexity.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's moderate complexity (4 parameters, no output schema, no annotations), the description is highly complete. It covers purpose, usage guidelines, behavioral details, parameter semantics through examples, and return format. The lack of output schema is compensated by explicitly describing the response structure (results with scores, match_type). No significant gaps remain for effective tool selection and invocation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 75%, so the schema already documents most parameters well. The description adds valuable context beyond the schema: it explains the query parameter's default behavior (searches both filenames and content), provides multiple search mode examples with prefixes, and clarifies tag hierarchy support. However, it doesn't add meaningful information about the other parameters (context_length, max_results, ctx) beyond what's in their schema descriptions.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool searches for notes by filename or content with smart ranking. It specifies the verb 'search' and resource 'notes', distinguishing it from siblings like list_notes (listing all notes) and search_by_date (searching by date). The opening sentence is specific and immediately communicates the core functionality.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides explicit guidance on when to use this tool (e.g., finding notes by name, content, tags, folders, properties) and when NOT to use it (e.g., searching by date, listing all notes, reading a specific note with exact path). It names specific alternative tools (search_by_date, list_notes, read_note) for excluded use cases, offering clear decision boundaries.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

update_note_toolA

Update the content of an existing note.

āš ļø IMPORTANT: By default, this REPLACES the entire note content. Always read the note first if you need to preserve existing content.

When to use:

  • Updating a note with completely new content (replace)

  • Adding content to the end of a note (append)

  • Programmatically modifying notes

When NOT to use:

  • Making small edits (read first, then update with full content)

  • Creating new notes (use create_note instead)

Returns: Update status with path, metadata, and operation performed

ParametersJSON Schema
NameRequiredDescriptionDefault
pathYesWhich note to update in your vault
contentYesNew content for the note. By default this REPLACES all existing content. Use merge_strategy='append' to add to the end instead.
create_if_not_existsNoAutomatically create the note if it doesn't exist yet
merge_strategyNoHow to handle existing content. 'replace' = overwrite everything (default), 'append' = add new content to the endreplace
ctxNo

TDQS

A4.6/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full burden of behavioral disclosure. It effectively describes key traits: the default destructive behavior ('REPLACES the entire note content'), the need to read first to preserve content, and the return format ('Update status with path, metadata, and operation performed'). However, it lacks details on permissions, rate limits, or error handling, leaving some gaps.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is well-structured and front-loaded, starting with the core purpose followed by important warnings and usage guidelines. Each sentence earns its place: the first states the action, the warning highlights critical behavior, and the bullet points provide clear context without redundancy. It's appropriately sized for a tool with multiple parameters and behavioral nuances.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's complexity (5 parameters, no annotations, no output schema), the description does a good job covering key aspects: purpose, usage, behavioral traits, and some parameter context. However, it doesn't fully explain the return values beyond a brief mention, and with no output schema, more detail on the 'Update status' would be helpful. It's mostly complete but has minor gaps.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is high at 80%, setting a baseline of 3. The description adds value by explaining the default behavior ('REPLACES the entire note content') and mentioning the 'append' option for 'merge_strategy', which complements the schema. It also implicitly clarifies that 'path' identifies the note and 'content' is the new text, though it doesn't detail all parameters like 'create_if_not_exists' or 'ctx'.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb ('Update') and resource ('content of an existing note'), making the purpose specific. It distinguishes from sibling tools like 'create_note_tool' (for creating new notes) and 'edit_note_section_tool' (for small edits), which helps differentiate its role in the toolset.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides explicit guidance with dedicated 'When to use' and 'When NOT to use' sections. It specifies scenarios like replacing content, appending, and programmatic modifications, while warning against small edits (suggesting 'read first') and directing to 'create_note' for new notes. This clearly defines when to choose this tool over alternatives.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

update_tags_toolA

Update tags on a note - either replace all tags or merge with existing.

When to use:

  • After analyzing a note's content to suggest relevant tags

  • Reorganizing tags across your vault

  • Setting consistent tags based on note types or projects

  • AI-driven tag suggestions ("What is this note about? Add appropriate tags")

When NOT to use:

  • Just adding a few tags (use add_tags)

  • Just removing specific tags (use remove_tags)

Returns: Previous tags, new tags, and operation performed

ParametersJSON Schema
NameRequiredDescriptionDefault
pathYesPath to the note
tagsYesNew tags for the note. Empty list removes all tags. Don't include # symbols. Supports hierarchical tags with forward slashes.
mergeNoTrue = add these tags to existing ones, False = replace all tags with this new list
ctxNo

TDQS

A4.6/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full burden of behavioral disclosure. It effectively explains the tool's behavior: it can replace or merge tags, and an empty tags list removes all tags (as noted in the schema). It also describes the return values. However, it doesn't mention potential side effects like error conditions or permissions needed, which keeps it from a perfect score.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is well-structured with clear sections (purpose, usage guidelines, returns) and uses bullet points for readability. Every sentence adds value, such as distinguishing from siblings and explaining parameter behavior, with no wasted words. It's appropriately sized for the tool's complexity.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given no annotations and no output schema, the description does a good job covering purpose, usage, and behavior. It explains the return values and key parameters. However, it doesn't address potential errors or edge cases (e.g., what happens if the path doesn't exist), which would enhance completeness for a mutation tool with 4 parameters.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 75%, so the description doesn't need to fully compensate. It adds value by clarifying the 'merge' parameter's semantics ('True = add these tags to existing ones, False = replace all tags with this new list') and implies usage of 'tags' and 'path' in context. However, it doesn't explain the 'ctx' parameter, which has no description in the schema, leaving a minor gap.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description starts with a clear, specific statement: 'Update tags on a note - either replace all tags or merge with existing.' This explicitly states the verb ('update'), resource ('tags on a note'), and distinguishes it from siblings like add_tags_tool and remove_tags_tool by mentioning replacement vs. merging. It goes beyond just restating the name/title.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description includes explicit 'When to use' and 'When NOT to use' sections with concrete scenarios (e.g., 'After analyzing a note's content to suggest relevant tags') and named alternatives (e.g., 'use add_tags' or 'use remove_tags'). This provides clear guidance on when to choose this tool over others.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

view_note_images_toolA

Extract and analyze images embedded in a note.

When to use:

  • Analyzing images referenced in a note's markdown content

  • Examining visual content within notes (screenshots, diagrams, etc.)

  • Extracting specific images from notes for analysis

When NOT to use:

  • Reading standalone image files (use read_image instead)

  • Getting note content without images (use read_note instead)

Returns: List of Image objects that Claude can analyze and describe

ParametersJSON Schema
NameRequiredDescriptionDefault
pathYesPath to the note containing images
image_indexNo
max_widthNoResize images wider than this to save memory. Images smaller than this are unchanged.
ctxNo

TDQS

A4.4/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full burden of behavioral disclosure. It effectively describes what the tool does (extract/analyze embedded images), specifies the return format (List of Image objects), and mentions that Claude can analyze/describe them. It doesn't cover error conditions, performance characteristics, or memory implications of image processing, but provides solid core behavioral information.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is well-structured with clear sections (purpose, when to use, when not to use, returns). Each sentence earns its place by providing essential information without redundancy. The front-loaded purpose statement immediately communicates the tool's function.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a tool with no annotations and no output schema, the description provides good contextual completeness. It explains what the tool does, when to use it, what it returns, and distinguishes it from alternatives. The main gap is lack of explicit mention of the 'max_width' parameter's memory-saving purpose, but overall it's quite comprehensive given the structured data limitations.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

With 50% schema description coverage, the description doesn't mention any parameters directly. However, the schema provides good documentation for the 4 parameters, including clear descriptions and examples for 'path' and 'image_index'. The description doesn't add parameter-specific context beyond what's implied by the tool's purpose, meeting the baseline for moderate schema coverage.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's purpose with specific verbs ('extract and analyze') and resources ('images embedded in a note'), distinguishing it from siblings like read_note (text only) and read_image (standalone files). The first sentence provides a concise, accurate summary of functionality.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description includes explicit 'When to use' and 'When NOT to use' sections with named alternatives (read_image, read_note). This provides clear guidance on when this tool is appropriate versus when to use sibling tools, covering both inclusion and exclusion criteria.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

A4.4/5.0
Disambiguation4/5

Most tools have distinct purposes with clear boundaries, such as read_note vs. get_note_info, or add_tags vs. update_tags. However, there is some overlap between search_notes and search_by_property/search_by_date, which could cause confusion about which to use for specific queries, though descriptions help clarify.

Naming Consistency5/5

Tool names follow a consistent snake_case pattern with clear verb_noun structures, such as create_note, delete_note, update_note, and search_notes. This predictability makes it easy to understand each tool's function at a glance across the entire set.

Tool Count3/5

With 27 tools, the count feels heavy for a note-taking server, though it covers a broad range of operations. While comprehensive, it may overwhelm users with too many specialized tools, such as separate search_by_date and search_by_property tools, where a more unified search could suffice.

Completeness5/5

The tool set provides complete CRUD and lifecycle coverage for Obsidian vault management, including note creation, reading, updating, deletion, moving, renaming, tagging, searching, and maintenance tasks like finding broken links or orphaned notes. No obvious gaps exist for the domain.
