Get Node Detail

pathrule_get_node
Read-only

Return a single node plus ids for attached memories, rules, and skills. Requires workspace_id to prevent cross-workspace ambiguity.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
node_idYesTree node UUID.
workspace_idYesWorkspace UUID from pathrule_list_workspaces.

Output Schema

TableJSON Schema
NameRequiredDescriptionDefault
okYestrue when the call succeeded. false when it did not, in which case `error` carries the reason and the success fields are absent.
errorNoPresent only when ok is false.
workspace_idNoWorkspace the node belongs to. A node outside the requested workspace is reported as a not_found error instead.

A4.5/5.0
Behavior4/5

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

Annotations declare readOnlyHint=true and destructiveHint=false, so the safety profile is already covered. The description adds behavioral context by specifying the return contents and explaining that workspace_id prevents cross-workspace ambiguity. No contradiction with annotations.

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?

Two efficient sentences: the first states the core behavior and return scope, and the second adds the key usage constraint. No wasted words or repetition of schema details.

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?

For a simple read-only retrieval with only two required parameters and an output schema, the description fully covers what an agent needs to invoke it correctly. Annotations handle safety, schema handles parameters, and the description clarifies purpose and scope.

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 100%, so the baseline is 3. The description adds value by explaining why workspace_id is required and tying node_id to the tree node concept. This meaningfully supplements the schema's basic field 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?

States a specific verb ('Return'), a distinct resource ('a single node'), and the exact payload scope ('plus ids for attached memories, rules, and skills'). This clearly separates it from sibling tools like pathrule_get_tree or pathrule_get_context.

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

Usage Guidelines4/5

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

The description gives clear context: use this for a single node and its attached references. It also notes the workspace_id requirement to prevent ambiguity. It does not explicitly mention an alternative tool or a when-not-to-use condition, but the single-node scoping is clear.

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

A3.8/5.0
Disambiguation4/5

Tools are grouped by resource (memory/rule/skill/workspace/snapshot/refresh) and mostly have distinct output shapes, so agents can usually pick the right one. A few retrieval tools (get_context, get_node, get_tree, goto) overlap in purpose, but their descriptions clarify resolution mode vs full tree vs context bundle.

Naming Consistency3/5

All tools share the pathrule_ prefix and mostly follow verb_noun, but the verbs are inconsistent: create_workspace vs write_memory, get_node vs read_memory, delete_skill vs remove_pattern, plus verb-only exceptions like goto, setup, and ping. The pattern is readable but not uniform.

Tool Count2/5

32 tools is above the 25-tool threshold and feels heavy for a single server, even with a broad domain. Several context-retrieval tools and read/list variants could potentially be consolidated, though each tool does have a specific purpose.

Completeness4/5

Core CRUD is covered for memories, rules, and skills, along with workspaces, snapshots, refresh tasks, and pattern import/removal. Minor gaps include no standalone list_rules/list_skills and no snapshot update/delete, but agents can work around these via get_context, goto, and get_tree.
