Connection Path

get_connection_path
Read-onlyIdempotent

Find the shortest path between two notes in your vault's link graph, uncovering how they are connected through intermediate notes.

Instructions

Find the shortest connection path between two notes in the link graph.

Treats links as undirected — a link from A to B or B to A both count as a connection. Uses BFS; max_depth is clamped to [1, 10].

Useful for discovering how two seemingly unrelated notes are connected through the vault's link structure (the "six degrees of separation" for your notes).

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
sourceYesVault-relative path of the starting note (e.g. 'Ideas/spark.md').
targetYesVault-relative path of the destination note.
max_depthNoMaximum number of hops to search. Default 10, max 10.
wait_for_pending_writesNoWhen True, wait until your recent write/edit/delete/rename operations have been applied to the index before answering, so the results reflect those changes. Use it right after modifying notes when this read must see them (e.g. right after a write/edit/delete/rename whose effect this read should reflect). Default False answers immediately from the current index — almost always already up to date; inspect the response's ``_meta.index_stale`` field to tell whether a write was still in flight. Bounded by a server timeout (default 60s); on timeout it answers from the current index rather than waiting longer.

Behavior4/5

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

Annotations already declare readOnlyHint=true and idempotentHint=true. The description adds extra behavioral details: treats links as undirected, uses BFS, and clamps max_depth to [1,10]. No contradictions. The description enriches transparency beyond 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?

The description is just three sentences, front-loaded with the core purpose, followed by algorithm details and a use case. Every sentence adds value with no 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?

The description covers the core algorithm, constraints, and a real-world use case. It does not explain the output format or common parameters like wait_for_pending_writes, but the output schema and schema descriptions compensate. Slightly more detail about response shape would improve completeness.

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 100%, so baseline is 3. The description mentions max_depth clamping, which is already in the schema. It does not add novel parameter details beyond what the schema provides, so it meets but does not exceed the baseline.

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 finds the shortest connection path between two notes in an undirected link graph using BFS, with max_depth clamped. This is distinct from sibling tools like get_backlinks or get_similar, which focus on individual links or similarity rather than paths.

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 a clear use case ('six degrees of separation for your notes') but does not explicitly state when not to use it or compare it to alternatives like get_backlinks or search. However, the purpose is sufficiently clear for an agent to infer appropriate contexts.

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