uv syncMCPサーバーはstdio経由で実行されるため、デバッグが困難になる場合があります。最適なデバッグ環境を実現するには、 MCP Inspectorの使用をお勧めします。
MCP インスペクターは、次のようにnpm経由で起動できます。
npx @modelcontextprotocol/inspector uv --directory /path/to/mcp-logseq run mcp-logseqCreate a new page in Logseq with properly structured blocks.
Fails if a page with the same title already exists (use update_page to modify existing pages). This makes retries safe: re-sending a create_page that timed out will not create numbered duplicates like "Page(1)".
Markdown content is automatically parsed into Logseq's block hierarchy:
Headings (# ## ###) create nested sections
Lists (- or 1.) become proper block trees
Code blocks are preserved as single blocks
YAML frontmatter (---) becomes page properties
Example content:
---
tags: [project, active]
priority: high
---
# Project Title
Introduction paragraph.
## Tasks
- Task 1
- Subtask A
- Task 2| Name | Required | Description | Default |
|---|---|---|---|
| title | Yes | Title of the new page | |
| content | No | Markdown content to parse into blocks (optional) | |
| properties | No | Page properties (merged with frontmatter if both provided) |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description carries full burden. It discloses failure on duplicate titles, retry safety, markdown parsing into block hierarchy, and property merging. Could mention return value or side effects, but covers key behaviors.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Well-structured with sections, example, and clear explanations. Slightly long but each part serves a purpose. No wasted sentences.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Covers input semantics, behavior, and constraints. Missing return value description, but given the tool's simplicity and no output schema, it is sufficiently complete for page creation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% (baseline 3). Description adds meaning by explaining how 'content' is parsed (markdown into blocks) and that 'properties' merge with frontmatter. Adds value beyond the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the action ('Create a new page') and the resource ('in Logseq with properly structured blocks'). It distinguishes from sibling tools like update_page by noting the fail condition for duplicate titles.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicitly states when to use (creating new pages) and when not to (if page exists, use update_page). Also explains retry safety, providing clear guidance for the agent.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Delete a block from LogSeq by its UUID.
| Name | Required | Description | Default |
|---|---|---|---|
| block_uuid | Yes | UUID of the block to delete |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations exist, and the description does not disclose behavioral traits such as irreversibility, cascading effects, permissions needed, or return value. For a destructive operation, this lack of detail is a significant gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is very concise (one sentence), which is efficient. However, it could be front-loaded with additional critical info, but the brevity does not detract from clarity.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the complexity (delete operation, single parameter, no output schema), the description lacks essential context about return values, error handling, and side effects, making it incomplete for safe agent invocation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema coverage is 100% with the parameter 'block_uuid' described. The description adds no further semantic meaning beyond 'by its UUID,' so it meets the baseline for adequate schema handling.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb ('Delete'), resource ('block'), and method ('by its UUID'), making it unambiguous. It distinguishes from sibling tools like 'delete_page' by specifying the object type.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool over alternatives (e.g., why not delete the parent page?), nor any prerequisites or context. The description simply states the action without usage direction.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Delete a page from LogSeq.
| Name | Required | Description | Default |
|---|---|---|---|
| page_name | Yes | Name of the page to delete |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. It states 'Delete a page' but does not disclose whether the operation is irreversible, what happens to associated content, or if any authorization is needed. For a destructive action, more behavioral context is essential.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence, highly concise and front-loaded. However, it may be too terse for a destructive operation; a slightly longer description with more detail would not harm conciseness. Still, no wasted words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple one-parameter tool with no output schema, the description is minimally adequate. It does not explain return behavior or confirmation, but given the low complexity, it covers the basic purpose. Missing details about side effects hold it back from a higher score.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100% with the parameter description 'Name of the page to delete', so the description adds no extra semantic value. Baseline 3 is appropriate as the schema handles the parameter documentation adequately.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
Description uses specific verb 'Delete' and resource 'page' from 'LogSeq', clearly distinguishing it from siblings like 'delete_block' or 'rename_page'. It immediately communicates the core action and scope.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives, prerequisites (e.g., page existence), or consequences. The description lacks explicit 'when to use' or 'when not to use' context, leaving the agent to infer from the name alone.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Find all pages that have a specific property, optionally filtered by value. Simpler alternative to the full query DSL.
| Name | Required | Description | Default |
|---|---|---|---|
| limit | No | Maximum number of results to return | |
| property_name | Yes | Name of the property to search for (e.g., 'status', 'type', 'service') | |
| property_value | No | Optional: specific value to match. If omitted, returns all pages that have this property. |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must disclose behavioral traits. It describes the core filtering behavior adequately but does not mention potential side effects, permissions, or return format. For a read-only search tool, this is acceptable but not thorough.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Two concise, front-loaded sentences. The first sentence states the core purpose, the second provides context on alternatives. No unnecessary words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity (3 params, 1 required, no output schema), the description covers the key functionality and use case. It could mention pagination or ordering, but for a basic search tool it is fairly complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with each parameter described in the schema. The description adds overall context but no additional detail beyond the schema, so baseline 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
Clearly states it finds all pages with a specific property, optionally filtered by value. Distinguishes itself by calling out it's a simpler alternative to the full query DSL.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicitly says it's a simpler alternative to the query DSL, implying when to use this tool. However, it does not mention exclusions or contrast with other sibling search tools like 'search' or 'query'.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Get a single block by its UUID. Returns the block content, properties, and child blocks (recursively). Useful for inspecting a specific block after finding its UUID via search or query.
| Name | Required | Description | Default |
|---|---|---|---|
| format | No | Output format (text or json) | text |
| block_uuid | Yes | UUID of the block to retrieve | |
| include_children | No | Whether to include child blocks recursively (default: true) |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full burden. It accurately states that it returns block content, properties, and recursive child blocks, implying a read-only operation. However, it does not mention error conditions or recursion depth limits.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences, no redundant information. The first sentence states the primary action; the second provides a usage hint. Efficient and front-loaded.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a straightforward get tool with 3 parameters and no output schema, the description adequately covers purpose and return content. It could mention that the output format is selectable, but that is in the schema.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so baseline is 3. The description adds no additional meaning to the parameters (block_uuid, include_children, format) beyond the schema descriptions.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it retrieves a block by UUID and returns content, properties, and child blocks. It distinguishes itself from sibling tools like search or get_page_content by focusing on a single block identified by UUID.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides a use case: 'inspecting a specific block after finding its UUID via search or query.' This gives context but does not explicitly exclude scenarios or name alternatives.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Get all pages and blocks that link to a specific page (backlinks/linked references).
| Name | Required | Description | Default |
|---|---|---|---|
| page_name | Yes | Name of the page to find backlinks for | |
| include_content | No | Whether to include the content of referencing blocks |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description must disclose behavioral traits. It only states what the tool returns, not that it is a safe read operation, potential performance implications, or any side effects. This is insufficient for a tool that queries links.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Single sentence with clear verb and object, front-loaded with key information. No unnecessary words or repetition.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema, the description could clarify the return format (e.g., 'returns a list of block references'). It is adequate for a simple list operation but lacks completeness for an agent to fully understand the output structure.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% (both parameters described in schema). Description adds no extra meaning beyond the schema, so baseline score of 3 applies.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states verb 'Get' and resource 'all pages and blocks that link to a specific page' with explicit mention of 'backlinks/linked references', distinguishing it from sibling tools that retrieve single blocks or page content.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool over alternatives (e.g., search for linking references), nor any mention of when not to use it. The description lacks context about prerequisites or typical use cases.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Get the content of a specific page from LogSeq.
| Name | Required | Description | Default |
|---|---|---|---|
| format | No | Output format (text or json) | text |
| max_depth | No | Maximum nesting depth to display (default: -1 for unlimited) | |
| page_name | Yes | Name of the page to retrieve | |
| resolve_refs | No | Resolve [[uuid]] page references to [[Page Name]] in DB mode (default: true) |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are present, so the description must convey behavioral traits. While 'Get' implies a read-only operation, it does not disclose potential side effects, authorization needs, rate limits, or error scenarios. The description is insufficient for a tool with no annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence that conveys the core purpose without unnecessary words. It is highly efficient and front-loaded, meeting the standard for conciseness.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description lacks details about return values, output format, or how the content is structured. Given that no output schema exists and there are 4 parameters, the description should explain that the content is returned in the specified format (e.g., text or JSON) and potentially mention nesting or reference resolution behavior.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema covers all parameters with descriptions (100% coverage), so the baseline is 3. The description adds no additional parameter-level information, but the schema already adequately explains each parameter’s purpose and defaults.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool retrieves page content from LogSeq, using a specific verb ('Get') and resource ('content of a specific page'). This differentiates it from sibling tools like list_pages (which lists pages) or delete_page (destructive operation).
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus alternatives. It does not mention prerequisites, limitations, or contrast with sibling tools like search or query. The agent is left to infer usage without explicit context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Get all pages within a namespace hierarchy (flat list). Use this to discover subpages of a parent page.
| Name | Required | Description | Default |
|---|---|---|---|
| namespace | Yes | The namespace to query (e.g., 'Customer', 'Projects/2024') |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Without annotations, the description carries the burden of behavioral disclosure. It correctly states it returns a flat list of pages, but omits details on output structure (e.g., page properties), pagination, or ordering. For a read operation, this is acceptable but lacking completeness.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Two concise sentences: first states the core function, second provides usage context. No unnecessary words, and information is front-loaded.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple 1-parameter tool with no output schema, the description covers the basic intent but lacks details on return format or limits. An agent may need to know the structure of returned pages to chain calls, but the description is not severely deficient.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% for the single parameter, and the description adds no new meaning beyond the schema's own description (e.g., 'The namespace to query (e.g., 'Customer', 'Projects/2024')'). Baseline of 3 is appropriate since the schema already documents the parameter adequately.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool retrieves all pages within a namespace hierarchy as a flat list. It uses a specific verb 'Get' and resource 'pages within a namespace hierarchy', and implicitly differentiates from sibling 'get_pages_tree_from_namespace' by contrasting flat vs. tree structure.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description explicitly says 'Use this to discover subpages of a parent page', providing a clear use case. However, it does not explicitly mention when not to use it or list alternatives like 'get_pages_tree_from_namespace' for tree views.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Get pages within a namespace as a hierarchical tree structure. Useful for understanding the full page hierarchy.
| Name | Required | Description | Default |
|---|---|---|---|
| namespace | Yes | The root namespace to build tree from (e.g., 'Projects') |
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 lacks disclosure of behavioral traits like error handling, permissions, or limits beyond the basic purpose.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences with no fluff. Efficiently conveys purpose and context.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema and a single parameter, the description explains the use case but omits details about the tree structure or limitations.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100% with the 'namespace' parameter described. The tool description adds minimal context beyond the schema, meeting the baseline.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb ('Get'), resource ('pages within a namespace'), and output format ('hierarchical tree structure'). It differentiates from sibling tool 'get_pages_from_namespace' by emphasizing hierarchy.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage context ('Useful for understanding the full page hierarchy') but does not explicitly mention when not to use or provide alternative sibling tools.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Insert a new block as a child or sibling of an existing block, enabling nested hierarchical structures
| Name | Required | Description | Default |
|---|---|---|---|
| content | Yes | Content text for the new block | |
| sibling | No | false (default) = insert as CHILD under parent_block_uuid. true = insert as SIBLING after parent_block_uuid at the same level. For multiple children under same parent, ALWAYS use false with the parent's UUID. | |
| properties | No | Optional block properties (e.g., {'marker': 'TODO', 'priority': 'A'}) | |
| parent_block_uuid | Yes | UUID of the reference block. If sibling=false, new block becomes a CHILD of this UUID. If sibling=true, new block becomes a SIBLING of this UUID (at the same level). |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, description carries burden. It discloses child/sibling behavior and provides a hint for multiple children. However, it omits details on ordering, error handling, 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.
Is the description appropriately sized, front-loaded, and free of redundancy?
Single sentence captures core functionality without redundancy. Front-loaded with verb and resource, efficiently conveying purpose.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a moderate-complexity tool with no output schema and no annotations, the description is adequate but not thorough. It lacks details on return values, error cases, and ordering of nested blocks.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema descriptions cover all parameters (100% coverage). Description rephrases the parent_block_uuid and sibling roles but adds no new semantics beyond the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states the tool inserts a block as child or sibling, with specific verb 'Insert' and resource 'block'. It distinguishes from sibling tools (e.g., update_block, delete_block) as the only insertion tool for nested hierarchies.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No explicit guidance on when to use this tool versus alternatives like update_block or set_block_properties. The sibling parameter description offers some context but no global usage criteria.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Lists all pages in a LogSeq graph.
| Name | Required | Description | Default |
|---|---|---|---|
| limit | No | Return at most this many pages (alphabetical). Omit for all. | |
| include_journals | No | Whether to include journal/daily notes in the list |
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 only says 'lists all pages', which implies a read-only operation but does not explicitly state that it is safe, that it returns a large dataset, or that it has any pagination or side effects. The description adds minimal behavioral context beyond the obvious verb 'list', which is a significant gap for a tool with no annotation support.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, direct sentence that front-loads the purpose without any fluff. It is appropriately concise for a simple listing operation. However, it might benefit from a brief mention of the optional parameters or alternatives, but this is a minor point given the excellent brevity.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a tool with two optional parameters, no annotations, and several sibling functions, the description is incomplete. It does not explain how the 'limit' or 'include_journals' parameters affect the result, nor does it clarify that the output may differ from other page-listing tools (e.g., namespace-specific listings). An agent presented with this description alone would not know whether to choose this over find_pages_by_property or get_pages_from_namespace, making it insufficient for correct tool selection and invocation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema covers both parameters (limit and include_journals) with clear descriptions and defaults, reaching 100% schema description coverage. The tool description itself adds no parameter-specific meaning, but since the schema already documents them thoroughly, a baseline of 3 is appropriate per the rubric.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb 'lists' and the resource 'all pages in a LogSeq graph', making the core purpose understandable. It implicitly distinguishes itself from content retrieval tools like get_page_content and property-based search like find_pages_by_property, but it doesn't explicitly name alternatives. The scope is clear, and the description is unambiguous, so it earns a 4 rather than a 5.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus its siblings. It doesn't mention that other tools exist for filtered or property-based page lookup (e.g., find_pages_by_property, get_pages_from_namespace) nor does it explain the trade-offs. With 17 sibling tools, the lack of any usage context leaves the agent to guess when this broad listing is appropriate.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Execute a Logseq DSL query to search pages and blocks. Supports property queries, tag queries, task queries, and logical combinations. See https://docs.logseq.com/#/page/queries for query syntax.
| Name | Required | Description | Default |
|---|---|---|---|
| limit | No | Maximum number of results to return | |
| query | Yes | Logseq DSL query string (e.g., '(page-property status active)', '(and (task todo) (page [[Project]]))') | |
| format | No | Output format (text or json). JSON returns raw result objects including block UUIDs and page info for deep linking. | text |
| result_type | No | Filter results by type | all |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Without annotations, description partially covers behavior: it searches pages/blocks, supports various queries. However, it doesn't clarify mutability (likely read-only), return format details beyond schema, error handling, or performance implications.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences plus a link, front-loaded with key information. Every part is necessary and succinct.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given 4 params, full schema coverage, no output schema, and no annotations, the description adequately explains purpose and provides a reference for syntax. Could be more complete with return structure or examples, but sufficient.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with detailed parameter descriptions. Description adds general context but no new parameter-specific information. Baseline 3 applies.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states it executes a Logseq DSL query to search pages and blocks, listing supported query types and providing a link to syntax. Distinguishes from sibling tools like search by focusing on DSL queries.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No explicit guidance on when to use this tool versus alternatives like search or find_pages_by_property. Implies use for complex DSL queries but lacks direct comparison.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Rename an existing page. All references throughout the graph will be automatically updated.
| Name | Required | Description | Default |
|---|---|---|---|
| new_name | Yes | New name for the page | |
| old_name | Yes | Current name of the page |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full burden. It discloses the critical behavior that all references are automatically updated, which is key for an AI agent to anticipate side effects.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Two succinct sentences with no extraneous information. Essential purpose and side effect are front-loaded.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple two-parameter tool with no output schema and no annotations, the description provides sufficient context: purpose, parameters implied, and the key side effect.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with clear parameter descriptions. The description adds no additional semantics beyond the schema, so it meets the baseline.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly specifies the action 'rename' and the resource 'an existing page', with a unique side effect (automatic reference updates) that distinguishes it from sibling tools like update_page or delete_page.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies this tool is used for renaming pages but does not explicitly state when to use it over alternatives like update_page or provide exclusion criteria.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Search for content across LogSeq pages, blocks, and files
| Name | Required | Description | Default |
|---|---|---|---|
| limit | No | Maximum number of results to return | |
| query | Yes | Search query text | |
| format | No | Output format (text or json). JSON includes block UUIDs and page identifiers for deep linking. | text |
| include_files | No | Include file name results | |
| include_pages | No | Include page name results | |
| include_blocks | No | Include block content results |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must disclose behavioral traits. It only states 'search for content' but does not mention read-only nature, performance implications, response structure, or any side effects. The agent cannot assess safety or cost.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single concise sentence. While it is front-loaded and brief, it could be slightly expanded to include behavioral context without becoming verbose.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Despite full schema coverage, the description lacks important context such as what types of content are searched (fuzzy match?), response format beyond the format parameter, and any search semantics. For a complex search tool with six parameters, the description is too brief.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so the baseline is 3. The description does not add any additional meaning beyond the schema. Each parameter is well-defined in the schema, so no penalty for missing description-level detail.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool searches across LogSeq pages, blocks, and files. It identifies the main resource and action, but does not differentiate from the sibling 'query' tool which might have overlapping functionality.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this search tool versus alternatives like 'query' or other tools. There are no usage examples, prerequisites, or exclusion criteria.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Set properties on a block in Logseq DB-mode. Properties must be defined on the block's tag/class. Use property display names (e.g. 'Content status', not the internal ident).
| Name | Required | Description | Default |
|---|---|---|---|
| block_uuid | Yes | UUID of the block to update | |
| properties | Yes | Properties to set as {name: value} pairs. Use display names (e.g. 'Content status': 'kiem') |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description bears full responsibility for behavioral disclosure. It mentions a precondition (properties must be defined on tag/class) but does not explain side effects like whether existing properties are overwritten, error handling, or return values. This is inadequate for a mutation tool with no annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is three sentences long, each serving a distinct purpose: stating the action, adding a constraint, and providing a usage example. There is no redundant or unnecessary text.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple set operation with two parameters and no output schema, the description covers the essential: what it does, a key constraint, and a formatting guideline. It could be improved by clarifying whether properties are merged or replaced, but given the tool's simplicity, it is largely sufficient.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so baseline is 3. The description adds value by explaining that property names must be display names (not internal identifiers) and that properties must be defined on the block's tag/class, which is a critical constraint not evident from the schema alone.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly identifies the action (set properties), the target (a block in Logseq DB-mode), and adds specificity with constraints on property definitions and display names, effectively distinguishing it from sibling tools like update_block.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides clear context on how to use the tool (use display names, properties must be defined on tag/class), but does not explicitly state when to prefer this over alternatives or when not to use it. A sibling like update_block exists but no differentiation is given.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Update the content of an existing LogSeq block by UUID.
| Name | Required | Description | Default |
|---|---|---|---|
| content | Yes | New content that replaces the block text | |
| block_uuid | Yes | UUID of the block to update |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Lacks details on destructive behavior, permissions, side effects, or error handling. Without annotations, the description should be more transparent.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Single sentence, 11 words, front-loaded with key action and scope, no filler.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Adequate for a simple 2-param update, but missing context on block existence requirements or return behavior.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so baseline 3. Description adds no extra meaning beyond the schema's parameter descriptions.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
Clearly states verb (update), resource (block), and scope (by UUID), distinguishing it from sibling tools like insert_nested_block or get_block.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool vs. alternatives (e.g., set_block_properties), or prerequisites like block existence.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Update a page in Logseq with new content and/or properties.
Supports two modes:
append: Add new blocks after existing content (default)
replace: Clear all existing blocks and add new content
Markdown is parsed into proper block hierarchy just like create_page. YAML frontmatter in content will be merged with explicit properties.
| Name | Required | Description | Default |
|---|---|---|---|
| mode | No | append: add after existing content. replace: clear page and add new content. | append |
| content | No | Markdown content to add or replace with | |
| page_name | Yes | Name of the page to update | |
| properties | No | Page properties to set/update |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description discloses key behaviors: two modes, Markdown parsing, YAML frontmatter merging. However, it does not mention what happens if the page doesn't exist, error handling, or side effects like irreversible deletion in replace mode. The disclosure is adequate but not complete.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Two concise paragraphs: first states purpose, second details modes and behavior. Every sentence adds information with no filler. Front-loaded with the primary action.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a 4-parameter tool with no output schema, the description covers modes, content processing, and property merging. It references create_page for context. Lacks return value description and error conditions, but otherwise sufficiently complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, baseline 3. The description adds value by explaining that 'mode' defaults to 'append', Markdown is parsed into block hierarchy, and YAML frontmatter in content merges with explicit properties. This goes beyond the schema's brief descriptions.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it updates a Logseq page with content/properties, explains two modes (append/replace), and distinguishes from create_page by implying modification of existing pages. The verb 'update' and the resource 'page' are specific.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No explicit guidance on when to use this tool versus siblings like create_page or delete_page. The description mentions that Markdown parsing is 'just like create_page' but does not provide when-to-use or when-not-to-use context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Each tool targets a clear resource (page vs block) and action, but search/query/find_pages_by_property and the two namespace getters have overlapping purposes that could cause an agent to pick the wrong one.
Most tools follow verb_noun (list_pages, create_page, get_block, delete_block), but 'search' and 'query' break the pattern as bare verbs, and set_block_properties could be seen as an update_block variant.
17 tools is slightly above the ideal 3-15 range, but the set covers pages, blocks, search, queries, namespaces, backlinks, and properties without obvious redundancy.
The surface provides full page and block CRUD plus search/query, namespaces, backlinks, and properties. Missing standalone root block creation and journal-specific tools, but core workflows are covered.
