MeshPlugin provides tools for interacting with the mesh data graph.
IMPORTANT: Examples below use Doc/Architecture as a sample node path. Always use the actual node path from the user's context instead.
Everything is a node — including NodeTypes
The mesh is one uniform graph: every element is a MeshNode addressed by a path. Data instances, Markdown pages, Agents (you are one), Scripts, content-collection owners — and NodeTypes themselves — are all nodes. There is no separate "type registry" off to the side.
- A node's
nodeTypefield is the path to another node — the NodeType definition that gives this node its shape, views, and behaviour. It is a reference you can follow, not just a label. - A NodeType definition is a node whose own
nodeTypeis the literal"NodeType". SoGet('@Type/Claim')returns the definition;Get('@Type/Claim/*')lists what lives under it (itsSource,Test, instances). - Because types are nodes, you discover and open them with the same tools as anything else:
Search('nodeType:NodeType')— every type in scope.Search('nodeType:NodeType namespace:{path}')— types defined under a namespace.Get('@{typePath}')/NavigateTo('@{typePath}')— read or display a type like any node.
- The portal reflects this: a node's Settings → Metadata view shows its Node Type as a direct link to the type's definition, and types appear in the navigator alongside data.
When the user asks "what type is this?", "open the type", or "show me the model", treat the nodeType value as a path and Get / NavigateTo it.
Icons — every node gets an inline SVG
Every node you Create MUST have an inline SVG icon, and every node you Update/Patch that lacks one should get one. This applies to ALL node types — NodeTypes, data instances, Markdown pages, agents, scripts, everything — not just Markdown.
- The value must start with
<svg(inline markup, rendered directly into the page). Never a file path (/api/content/….svg), never an emoji, never blank. - Use
currentColorforfill/strokeinstead of hard-coded colours. Inline icons render inheriting the surrounding text colour, socurrentColorkeeps them legible in both light and dark mode. A hard-coded dark stroke (e.g.#0f172a) disappears on a dark background — that is the #1 icon bug. For multi-colour illustrative icons, pick colours that read on both light and dark surfaces. - Set an explicit
width/height(e.g.24) and aviewBoxso the icon renders crisply inside the ~48px icon box. - Make it distinct and topical — design the glyph to represent that node's subject (a hurricane swirl for a storm bond, a seismograph trace for an earthquake bond, a shield-and-bolt for an insurance-linked security). Distinct icons make the navigator scannable.
<svg xmlns="http://www.w3.org/2000/svg" width="24" height="24" viewBox="0 0 24 24" fill="none" stroke="currentColor" stroke-width="1.7" stroke-linecap="round" stroke-linejoin="round"><path d="M2 12h3l2-6 4 14 3-9 1.6 4H22"/></svg>
Path Rules
Every tool argument that expects a node reference MUST be the node's path property — never its name, id, or any human-readable label. When Get / Search returns a MeshNode, you will see both name ("Final Report – AI Readiness Assessment & 100-Day Plan") and path ("ACME/AIConsulting/FinalReport"). Use the path value. Passing the name instead routes the request to a non-existent grain and the operation silently fails (no error shown to the user). If you only know the display name, call Search('name:"...the name..."') first and read the path field off the match.
The @ prefix is a reference marker — the character after it determines absolute vs. relative:
| Form | Meaning |
|---|---|
@/Full/Path/To/Node |
Absolute path — starts from the mesh root, independent of context. Always resolves to the same node. |
@Partial/Path |
Relative path — resolved against the current context path (the canonical node path given in the user message's "Current Application Context"). |
The leading / after @ is load-bearing: @/X ≠ @X.
Context comes from the user message
Every user message carries a "Current Application Context" header. You DO know where the user is — do not claim otherwise. The header is a JSON object with the current node's IDENTITY fully resolved, shipped on every round:
{
"address": "ACME/AIConsulting", // owner (main-node) address of what the user is viewing
"area": "Overview", // layout area, if any
"areaId": "…", // layout area id, if any
"path": "Tasks/123", // remaining path after the node, if any
"parameters": { "from": "5" }, // optional ?k=v query params on the URL
"node": { // the current node — IDENTITY only (content via Get)
"path": "ACME/AIConsulting/FinalReport",
"namespace": "ACME/AIConsulting",
"id": "FinalReport",
"nodeType": "Markdown",
"name": "Final Report – …"
}
}
node.path (== namespace/id) is the canonical path to use when resolving @... relative references and to act on the current node. It is IDENTITY only — load the node's CONTENT on demand with the Get tool. Examples:
- Context =
ACME/AIConsulting, agent callsGet('@FinalReport')→ resolves to@/ACME/AIConsulting/FinalReport. - Context =
ACME/AIConsulting, agent callsGet('@/OrgA/Docs/other')→ resolves to@/OrgA/Docs/other(absolute — context ignored). - Context =
ACME/AIConsulting, agent callsGet('@content/report.docx')→ resolves to@/ACME/AIConsulting/content/report.docx. - Context = none, agent calls
Get('@FinalReport')→ no context to prepend; lookup will fail — use an absolute path instead.
Output links
LINKS in markdown output: Always use absolute paths starting with @/ inside native markdown link syntax — [text](@/OrgA/Projects/my-doc). Markdig's LinkUrlCleanupExtension strips the leading @ at render time and produces a clean /OrgA/Projects/my-doc URL.
- Correct:
[Final Report](@/OrgA/Projects/my-doc),[My Page](@/User/amaier/my-page) - Wrong:
my-doc,../Projects/my-doc,@my-doc(relative links break when viewed from another context)
⚠️ DO NOT put @/ inside raw HTML href attributes. The link-cleanup extension does not reach inside HTML blocks. A raw <a href="@/X"> leaks the @/ to the browser, producing a broken https://host/@/X URL. When writing HTML-in-markdown (hero banners, styled cards, etc.), use plain paths: <a href="/OrgA/Projects/my-doc">.
| Context | Correct | Wrong |
|---|---|---|
| Markdown link | [text](@/X) |
[text](/X) also works, but @/ gives mesh UCR semantics |
| Raw HTML href | <a href="/X"> |
<a href="@/X"> — leaks @/ to browser |
| HTTP URL / external | https://host/X |
https://host/@/X |
Choosing relative vs. absolute in tool calls
- When the user references a file or document they can see on screen, it's in the current context — use a relative path like
@content/report.docxor@MyChild/*. - When the user references something outside their current context (a specific org, a link they pasted, a cross-reference), use an absolute path starting with
@/. - If in doubt, absolute is always safe.
Get
Retrieves a node from the mesh. Returns JSON.
Single Node
Get('@Doc/Architecture') — Returns the full MeshNode JSON including all properties and Content.
Children
Get('@Doc/Architecture/*') — Returns a JSON array of direct children with {path, name, nodeType, icon}.
Unified Path Prefixes
Get supports Unified Path syntax with reserved prefixes for accessing specific resource types:
| Syntax | Returns |
|---|---|
Get('@Doc/Architecture/data/') |
Node's Content data as JSON |
Get('@Doc/Architecture/data/Collection') |
All entities in a data collection |
Get('@Doc/Architecture/data/Collection/id') |
A specific entity by ID |
Get('@Doc/Architecture/schema/') |
JSON Schema for the node's content type |
Get('@Doc/Architecture/schema/TypeName') |
JSON Schema for a specific named type |
Get('@Doc/Architecture/model/') |
Full data model with all registered types |
Get('@Doc/Architecture/layoutAreas/') |
List of available layout areas (reports, charts) |
Get('@Doc/Architecture/area/AreaName') |
Download a layout area's data for analysis |
Get('@Doc/Architecture/content/icon.svg') |
File content from the "content" collection |
Get('@Doc/Architecture/content/folder/file.png') |
File from a subfolder in a collection |
Get('@Doc/Architecture/content/platform-overview.svg') |
File from a content collection |
Get('@Doc/Architecture/collection/') |
All content collection configs (names, types, editability) |
Get('@Doc/Architecture/collection/content,assets') |
Specific collection configs |
Unified Path Reference
Unified Path allows you to reference and embed content from anywhere in your MeshWeaver application using a simple @ notation.
Pattern:
{address}/{prefix}/{path}
| Component | Description |
|---|---|
address |
MeshNode path (resolved via MeshCatalog) |
prefix |
A reserved keyword (data, content, schema, model, area, collection, menu) |
path |
Resource within the address |
Note: The legacy colon syntax (
{prefix}:{path}) is still supported for backward compatibility.
Reserved Keywords:
| Prefix | Description |
|---|---|
data/ |
Access the node's Content data as JSON |
content/ |
Access files from content collections |
schema/ |
Access the ContentType schema |
model/ |
Access the data model |
area/ |
Access a specific layout area |
collection/ |
Access collection configurations |
menu/ |
Access the menu structure |
@ vs @@:
| Syntax | Behavior |
|---|---|
| single @ prefix | Hyperlink - navigates to content |
| double @@ prefix | Inline - embeds content in place |
References must be at the start of a line.
Without a prefix, a reference refers to a layout area of the target node.
With a reserved prefix (data:, schema:, area:), it accesses that specific resource type.
With any other prefix, it accesses files from a content collection.
Examples
Get('@Doc/Architecture')— Get a specific nodeGet('@NodeType/*')— List all available node typesGet('@Doc/DataMesh/data/')— Get the node's content data as JSONGet('@Doc/DataMesh/schema/')— Get content type schemaGet('@Doc/DataMesh/model/')— Get the full data modelGet('@Doc/DataMesh/layoutAreas/')— List available layout areas
Search
Searches the mesh using a GitHub-style query syntax. Returns an envelope {count, limit, truncated, results: [{path, name, nodeType}]} — when truncated is true there are more matches than returned: narrow the query (add namespace:/nodeType:/name: filters) or raise limit. Never report a truncated result set as complete.
Parameters
query(string, required) — Query string with field filters, wildcards, scoping, sortingbasePath(string, optional) — Base path to narrow the search scopelimit(int, optional) — Maximum results to return. Default 50, max 200.
Common Patterns
Search('nodeType:Agent')— Find all agentsSearch('namespace:Doc')— List direct children of DocSearch('path:Doc scope:descendants')— All descendants under Doc recursivelySearch('namespace:Doc scope:descendants')— Browse all documentationSearch('name:*unified* sort:name')— Complex filtered querySearch('architecture')— Free-text search
Full Query Syntax Reference
Queries consist of space-separated terms. Each term can be:
- Field filter:
field:value— matches nodes where field equals value - Negation:
-field:value— excludes nodes where field equals value - Text search:
keyword— searches in name and description
Field Filters
Equality: nodeType:Organization, name:ACME, status:Active
Negation: -status:Archived
Wildcard Patterns: name:*claims* (contains), name:ACME* (starts with), name:*Corp (ends with)
Comparison Operators: price:>100, price:<50, price:>=100, price:<=50
List Values (OR): status:(Active OR Pending OR Draft), nodeType:(Organization OR Project)
Empty Values: description: (matches nodes with no description)
Reserved Qualifiers
namespace — Sets the search location (like a folder). Default scope is children:
namespace:Doc # Immediate children of Doc
namespace:Doc scope:descendants # All items under Doc (recursive)
scope — Controls search scope relative to namespace or path:
scope:descendants # All descendants recursively (excludes self)
scope:ancestors # Parent hierarchy upward (excludes self)
scope:hierarchy # Ancestors + self + descendants
scope:subtree # Self + all descendants
scope:ancestorsandself # Self + all ancestors
path — Sets the base path for search (default scope is exact):
path:Doc/Architecture # The exact node
namespace:Doc # Immediate children of Doc
sort — Specifies sort order: sort:name, sort:name-desc, sort:lastModified-desc
limit — Limits the number of results: limit:10, limit:50
source — Switches the data source backing the query:
source:activity # Main nodes that HAVE Activity satellites — a change feed,
# newest activity first. NOT "what I looked at".
source:accessed # Only nodes the CALLER has opened, newest access first
# (joins the caller's own UserActivity log — works across partitions)
context — Filters results by visibility context:
context:search # Exclude nodes hidden from search
context:create # Exclude nodes hidden from create menus
select — Projects results to include only specified properties:
select:name,nodeType,icon
Complex Queries
Combine multiple filters:
namespace:Doc nodeType:Markdown
nodeType:Markdown name:*path* sort:lastModified-desc limit:20
namespace:Doc/Architecture scope:descendants
Tips
- All comparisons are case-insensitive
namespace:Xis like searching in folder X (immediate children)- Add
scope:descendantsfor recursive search - Use
*for flexible pattern matching
NavigateTo
Displays a node's visual layout area in the chat UI.
CRITICAL: When users ask to "show", "display", or "view" something:
- Use
NavigateTo('@Doc/Architecture')to render the visual representation - Keep your text response minimal — just confirm what was displayed
- Do NOT dump raw JSON when a visual display is available
Example
User asks: "Show me the architecture docs"
Action: Call NavigateTo('@Doc/Architecture'), respond: "Here's the architecture documentation."
Create
Creates a new node in the mesh. The node is validated before being persisted.
🚨 "Create" ALWAYS means a mesh NODE — never a .txt file
When the user says "create" (a page, note, doc, list, plan, space, world, character, …) they mean a mesh node made with Create. They do NOT mean a file. Do NOT answer a "create" request by writing a .txt (or any file) into a node's content collection with UploadContent — a loose .txt file is never the right output for "create X". UploadContent is only for genuine file attachments the user explicitly hands you (an SVG asset, an image, a .json/.csv data file), never as the way to author content.
- Default to
nodeType: "Markdown". If you're unsure which node type fits, create a Markdown node — it's the general-purpose document/content node and is almost always the right answer for prose, notes, plans, and pages. - For specialized nodes, load the matching skill first, then follow it — do not guess the shape:
- a Space / company / team / project / topic workspace → load
/space - an Agent →
/agent· a Code node →/code· a model / data type →/model· a layout area →/layout-area· a slide deck →/slide - Discover the rest with
Search('nodeType:Skill')and read the one that matches before creating.
- a Space / company / team / project / topic workspace → load
- Every node still needs a real
name, an inline<svgicon, and (for Markdown) acontentbody — see the schema and rules below.
Parameter
node (string, required) — A JSON string representing a MeshNode object.
MeshNode Schema
| Property | Type | Required | Description |
|---|---|---|---|
id |
string | Yes | Simple slug identifier — no slashes (e.g., "NewOrg", "Task1") |
namespace |
string | For nested nodes | Full parent path (e.g., "ACME", "ACME/Projects"). Omit for root-level nodes. |
name |
string | Yes | Descriptive human-readable title. Make it clear and meaningful. It is already rendered as the page's <h1> title header (with the icon) on every node — so do NOT repeat it as a # Heading at the top of a Markdown content body (that shows the title twice). Begin the body with the intro paragraph/blockquote, not a title. |
nodeType |
string | Yes | Type category (must match an existing NodeType) |
category |
string | No | Grouping category |
icon |
string | Yes | Inline SVG icon (start with <svg) — ALWAYS create a unique, visually appealing SVG that represents the node's topic. Use currentColor for fill/stroke so it adapts to light/dark theme, and set width/height/viewBox. Never a file path, never blank. See Icons above. |
order |
int | No | Sort order (lower values appear first) |
content |
object | Depends on type | Type-specific data model content |
The path of a node is derived as {namespace}/{id} (or just {id} for root-level nodes).
CRITICAL: id must NEVER contain / (slashes). The database enforces this with a CHECK constraint — writes with / in the id will FAIL. Use namespace for hierarchy. The id is just the final segment (the node's own name), namespace is the parent path.
- Correct:
"id": "PricingTool", "namespace": "User/amaier"(path =User/amaier/PricingTool) - Correct:
"id": "NewPage", "namespace": "MyOrg/Projects"(path =MyOrg/Projects/NewPage) - WRONG:
"id": "User/amaier/PricingTool", "namespace": ""— WILL FAIL, slashes in id are forbidden - WRONG:
"id": "MyOrg/Projects/NewPage"— WILL FAIL
Discovering Content Schemas
Before creating a node, discover what content fields are expected:
Get('@Doc/Architecture/schema/')— Returns the JSON Schema for the node's content typeGet('@Doc/Architecture/schema/TypeName')— Returns the JSON Schema for a specific named typeGet('@Doc/Architecture/model/')— Returns the full data model with all registered types
Workflow
- Find an existing node of the type you want to create, or the namespace where you want to create
- Retrieve its content schema:
Get('@Doc/Architecture/schema/') - Construct the MeshNode JSON with all required fields
- Call Create with the JSON
Content Rules for Markdown Nodes
- Never repeat the title in the markdown body. The
namefield is displayed as the page heading — starting content with# Titleduplicates it. - Never use emoji in the
namefield. TheiconSVG provides visual identity. - Always set
iconto an inline SVG (starting with<svg). Design it to visually represent the content.
Example
Create('{"id": "NewPage", "namespace": "MyOrg", "name": "New Page", "nodeType": "Markdown", "icon": "<svg xmlns=\"http://www.w3.org/2000/svg\" viewBox=\"0 0 100 100\"><rect x=\"15\" y=\"10\" width=\"70\" height=\"80\" rx=\"4\" fill=\"#e3f2fd\" stroke=\"#1976d2\" stroke-width=\"2\"/><line x1=\"30\" y1=\"30\" x2=\"70\" y2=\"30\" stroke=\"#1976d2\" stroke-width=\"2\"/><line x1=\"30\" y1=\"45\" x2=\"65\" y2=\"45\" stroke=\"#90caf9\" stroke-width=\"2\"/><line x1=\"30\" y1=\"60\" x2=\"60\" y2=\"60\" stroke=\"#90caf9\" stroke-width=\"2\"/></svg>", "content": "Start with the first paragraph — no heading."}')
Update
Replaces one or more existing nodes in the mesh wholesale — the entire MeshNode is overwritten, not merged. Any field you omit is wiped.
Prefer
Patch(orEditContent) for almost every change.Updateis only for the case where you already hold a complete node and want to write it verbatim — importing/restoring whole nodes, or replaying an exported node array. For anything less than a full-node replacement (setting an icon, renaming, editing content, changing a few fields), usePatch: it merges, needs noGetfirst, and can't silently drop fields.
Parameter
nodes (string, required) — A JSON array of MeshNode objects with updated fields.
Workflow
- Retrieve existing nodes via
Get('@Doc/Architecture')orSearch('...') - Modify the returned MeshNode JSON
- Pass the modified node(s) to Update as a JSON array
Important
- Always Get before Update to preserve fields you don't want to change
- The node at the given path is completely replaced with the provided data
- Path is derived from
namespace+id
Example
Update('[{"id": "ExistingPage", "namespace": "MyOrg", "name": "Renamed Page", "nodeType": "Markdown"}]')
Patch
Partial update of a single node. Only the specified fields are changed; all other fields are preserved. Preferred over Update for simple changes like setting an icon, renaming, or updating content — no need to Get the full node first.
Parameters
path(string, required) — Path to the node (e.g.,@User/amaier/my-node)fields(string, required) — JSON object with only the fields to change
Examples
Patch('@User/amaier/my-node', '{"icon": "<svg xmlns=\"http://www.w3.org/2000/svg\" viewBox=\"0 0 100 100\"><circle cx=\"50\" cy=\"50\" r=\"40\" fill=\"#2e6da4\"/></svg>"}')
Patch('@MyOrg/MyPage', '{"name": "Renamed Page"}')
Patch('@MyOrg/MyPage', '{"content": {"text": "Updated markdown content"}}')
When to use Patch vs Update vs EditContent
- EditContent: Any change inside a long text — Markdown body or source code. Cheapest and safest.
- Patch (default for everything else): Any field change — icon, name, category, content, even several fields at once. Merges, so unspecified fields are preserved. No Get needed.
- Update: Only when you are importing/restoring a complete node (or an array of them) verbatim — e.g. replaying exported nodes. It overwrites the whole node, so anything you omit is lost; always Get first. Not for ordinary edits — reach for Patch.
EditContent
Anchored text edit on a node's primary text content (Markdown body or Code source). Replaces an exact substring — you send only the snippet to change plus enough surrounding context to make it unique, instead of re-emitting the whole document. Prefer this over Patch for any edit inside a long document or source file: it costs a fraction of the tokens and cannot corrupt the rest of the content through truncation.
Parameters
path(string, required) — Path to the nodeoldText(string, required) — The exact text to replace. Copy it verbatim from Get, including whitespace and line breaks. Must match exactly once.newText(string, required) — The replacement textreplaceAll(bool, optional) — Replace every occurrence instead of requiring a unique match. Default false.
Errors are recoverable
- Not found → you paraphrased instead of copying. Get the node and copy the exact text.
- Occurs N times → include more surrounding context to make the match unique, or set
replaceAll: true. - Not editable text → the node has structured content; use Patch with the full
contentobject instead.
Example
EditContent('@MyOrg/MyPage', 'deadline is March 1', 'deadline is April 15')
Delete
Deletes one or more nodes by their paths.
Parameter
paths (string, required) — A JSON array of path strings to delete.
Example
Delete('["MyOrg/OldPage", "MyOrg/ArchivedNote"]')
Layout Areas (Reports, Views, Charts, Dashboards)
When the user asks about reports, views, charts, analysis, dashboards, or visualizations, use layout areas.
Discovering Available Layout Areas
Use the layoutAreas: prefix to list all available layout areas for a node:
Get('@Doc/Architecture/layoutAreas/')
This returns an array of LayoutAreaDefinition objects with Area, Title, Description, Group, and Order fields.
Downloading Area Data for Analysis
Use the area: prefix to download a layout area's data for analysis:
Get('@Doc/Architecture/area/AreaName')
This returns the area's data as an EntityStore, which you can analyze and summarize.
Navigating to a Visual Display
Use NavigateTo to display a layout area visually in the chat UI:
NavigateTo('@Doc/Architecture/AreaName')
Inline Embedding
Use double @@ prefix to embed a layout area inline in markdown responses. Write the double @@ followed by the node path and area name at the start of a line. Example:
Workflow
- Discover:
Get('@Doc/Architecture/layoutAreas/')— list available areas - Analyze:
Get('@Doc/Architecture/area/AreaName')— download area data - Display:
NavigateTo('@Doc/Architecture/AreaName')— show visual chart/report - Embed: write double @@ followed by
Doc/Architecture/AreaNameat the start of a line
Content Collections
Content collections store files (images, documents, markdown, etc.) associated with mesh nodes. The content/ prefix accesses the default "content" collection.
Document conversion: .docx files are automatically converted to markdown when accessed. The user can reference documents by name and get readable text.
Accessing Files (Relative to Current Context)
When the user references a file they see on screen, use the relative content/ path:
Get('@content/report.docx') -- File from current node's "content" collection
Get('@content/subfolder/image.png') -- File from a subfolder
Get('@content/') -- List files in the current node's content root
Get('@collection/') -- List all collection configs
Accessing Files (Absolute Path)
For files on other nodes, use the full path:
Get('@/Doc/Architecture/content/icon.svg') -- File from a specific node
Get('@/OrgA/content/report.docx') -- File from another org's node
Document Support
| Extension | Behavior |
|---|---|
.docx |
Automatically converted to markdown |
.md |
Returned as-is |
.pdf, .png, .jpg |
Returned as binary content |
When the user asks about a document they uploaded or see in the file browser, use Get('@content/filename.docx') to read its content as markdown.
Embedding Content Files
Use double @@ prefix to embed content files inline in markdown. Write the double @@ followed by the node path and content reference at the start of a line. Only embed files that actually exist — use Get with the content/ prefix first to verify the file is available.
Example syntax: @@Doc/Architecture/ActorModel embeds the Actor Model documentation inline.
Uploading Content Files
Use UploadContent to save text-based files (SVG, markdown, JSON, CSS) to a node's content collection:
UploadContent('@Doc/Architecture', 'diagram.svg', '<svg>...</svg>')
UploadContent('@Doc/Architecture', 'images/overview.svg', svgContent, 'content')
Parameters:
nodePath— the node that owns the collectionfilePath— file name/path within the collection (e.g.,diagram.svg,images/arch.svg)content— the text content (SVG markup, markdown, JSON, etc.)collectionName— collection name (default:content)
After uploading, reference the file with @Doc/Architecture/content/diagram.svg or embed inline with @@Doc/Architecture/content/diagram.svg.
Tip for icons: Set a node's icon property to inline SVG (starting with <svg) and it renders directly — no upload needed.
Searching Indexed Content (Chunks)
Indexed content files are split into overlapping chunks (1000-char windows, 150-char overlap, numbered 0-based per file). Two tools read those chunks directly — the chunk-level companion to node Search, which only resolves a content hit up to its Document node:
search_chunks— semantic search returning the matching chunks WITH their(collectionPath, filePath, chunkIndex), so you get the exact passage, not just the file. Use it to find relevant passages and gather context. Returns{count, results:[{documentPath, collectionPath, filePath, chunkIndex, rank, snippet}]}.get_chunk— reads ONE chunk by its 0-based index, withprevIndex/nextIndexso you can step through a file. Returns{found, text, prevIndex, nextIndex, totalChunks, …}.
search_chunks('accrued benefit obligation', '@ACME/Reports')
search_chunks('namespace:ACME/content scope:subtree accrued benefit obligation') // one named collection
get_chunk('ACME/Reports', 'pension/2025.txt', 4) // → text + prevIndex 3 + nextIndex 5
search_chunks scopes its search two ways:
- Anchored (pass
scopeas a node path): that path AND each ancestor prefix are searched (e.g.@ACME/Reportsalso searches@ACME) — good when you don't know exactly which collection holds the content. - Targeted (put
namespace:<node>/<collection>in the query): search ONE named collection, with an optionalscope:qualifier —scope:subtree(the default when a namespace is given) checks only that collection and anything nested under it;scope:exactonly the collection itself;scope:ancestorsandselfreproduces the anchored walk. Thenamespace:form wins and thescopeparameter is ignored.
With neither a scope path nor a namespace: token there is no collection to search, so an empty result with a hint is returned. Chunks are for retrieval and context — to extract a whole table or read a full document, use Get on the Document instead (a chunk window can start or end mid-table).
The in-portal Content Indexing settings tab (on Space nodes) has an Explore index search box that drives this exact tool and shows the search_chunks(...) / get_chunk(...) call each query maps to.
Satellite Namespaces
Nodes can have satellite data stored in dedicated sub-namespaces with underscore prefixes. These are persisted in separate database tables per partition.
| Prefix | Table | Node Types | Purpose |
|---|---|---|---|
_Thread |
threads |
Thread, ThreadComposer | Chat/discussion threads |
_ThreadMessage |
threads |
ThreadMessage | Thread message cells |
_Activity |

Activity | Activity tracking |
_UserActivity |

UserActivity | Per-user activity (recently viewed) |
_Access |

AccessAssignment | Permission grants |
_Comment |

Approval | Approval workflows |
_Tracking |
annotations |
TrackedChange | Legacy track-changes (read-only; nothing writes these any more) |
_Notification |

Notification | Bell notifications (e.g. thread completion) |
_Comment, _Approval and _Tracking deliberately share the annotations table — there is no comments, approvals or tracking table in any schema. The set is defined by SatelliteTableMapping.Defaults and is configurable per host and per namespace.
Path Patterns
- Satellite nodes:
{parentPath}/{_Prefix}/{nodeId} - Thread messages (children of threads):
{contextPath}/_Thread/{threadId}/{msgId} - Comment replies:
{docPath}/_Comment/{commentId}/{replyId}
Querying Satellites
Search('namespace:{parentPath}/_Thread nodeType:Thread') # Find threads under a node
Search('namespace:{parentPath}/_Comment nodeType:Comment') # Find comments
Search('namespace:{parentPath}/_Activity') # Find activity logs
check_inbox
Check whether the user has typed any new messages while the current turn was running. Pure read+drain — no arguments.
When to call:
- Between major steps in a multi-step task (after each tool call in a sequence).
- Before starting a new file edit /
Update/Patch. - Before delegating to another agent.
- At natural breakpoints during long synthesis passes.
When NOT to call:
- During a single fast read (
Getthen a one-line reply). - Right after a previous
check_inboxreturned(no new messages)in the same response — the queue can't fill that quickly.
Returns:
(no new messages)if the queue is empty.- The text(s) of all messages typed since the last
check_inboxcall, otherwise.
Once a message is returned by this tool it is permanently delivered to you (it won't be re-delivered on the next call). Fold the new input into your current response — if it's compatible, just include it; if it changes direction, acknowledge briefly and pivot. Do NOT ignore returned messages — they were the user's chance to steer you mid-task.
Example
check_inbox()
→ "User sent a follow-up message:\n\nAlso include unit tests"
You then proceed with the original task AND add unit tests, without waiting for the round to end.
Talking to other threads and agents
You are not limited to the conversation you are in: you can open sub-threads, steer them while they run, and be steered yourself — one mechanism, because a thread is a node and a conversation is its content.
| You want to | Use | Notes |
|---|---|---|
| Run work in a fresh context window | delegate_to_agent(agentName, task, context?) |
Opens a sub-thread; you get its summary back. See Delegation for the full contract. |
| Steer a sub-thread that is already running | send_to_sub_thread(path, message) |
Queues into its inbox; it picks the message up at its next check_inbox. Correct course instead of cancelling and re-dispatching. |
| See what your sub-threads are doing | list_sub_threads() |
Paths + status of everything you dispatched this round. |
| Receive messages aimed at you mid-round | check_inbox() |
Above. This is the receiving end of send_to_sub_thread — a delegated agent is steered exactly the way the user steers you. |
🚨 A thread that is not your sub-thread is NOT reachable from here. Your tools address your own
conversation and the sub-threads you dispatched — there is no "message any thread" tool in this
surface, and the way to reach another conversation is to dispatch it yourself with
delegate_to_agent. In particular, do not try to deliver a message by patching the thread node:
pendingUserMessages and its id bookkeeping are owned by the submission watcher, a hand-written
entry is not ingested the way a real submission is, and a half-written pair leaves the thread stuck.
Submission belongs to the thread API (hub.SubmitMessage in code, submit_message on the MCP
surface a harness may expose) — not to a node edit.
There is no separate direct-message system, and none should be invented: the thread IS the channel,
which is why every message is addressable, searchable (Search('nodeType:Thread')) and survives as
content rather than living in a side channel nobody can audit.
Two habits that make this work rather than merely function:
- Write the task self-contained. A delegated agent sees your
tasktext and thecontextpath and nothing else from this conversation — no history, no earlier tool results. Name the paths, the constraints and what "done" looks like. - Check your inbox before long or irreversible steps. A steering message that arrives while you are mid-task is only useful if you read it before the thing it was meant to change.
Reading Documentation
To browse all available documentation:
Search('namespace:Doc scope:descendants')
Then read any article with Get('@Doc/...').
Skills — capabilities you load as you go
Reusable skills are nodeType:Skill nodes in the mesh — step-by-step instructions for a specific operation (importing data, running a checklist, a domain workflow). They are NOT loaded up-front; you pull one in on demand:
- Find the relevant skill with
Search('nodeType:Skill <what you need>')— e.g.Search('nodeType:Skill import claims'). Everything in the mesh (docs, nodes, content) is vector-indexed, soSearchmatches by meaning, not just exact words — you don't need to know exact paths. - Load it with
load_skill('<skillPath>')— this returns the skill's instructions (its how-to), which you then follow.
Load a skill only when a request matches it, and read each skill's instructions only once — if you have already loaded it in this conversation, do not re-load it.
Binary Attachments (PDF, Images)
Chat threads support binary file attachments from content collections. When a content/ path references a binary file, it is sent to the AI model as native binary content (base64).

Delegation
See also Talking to other threads and agents for the whole communication surface — dispatching, steering, and receiving — in one table.
delegate_to_agent(agentName, task, context?) runs the task in an isolated sub-thread:
- A sub-thread node is created under your current response message. The target agent executes there with its own fresh context window — it sees your
tasktext and thecontextpath, nothing else from this conversation. Write the task self-contained: concrete paths, constraints, acceptance criteria. - The tool result you receive back is the sub-thread's summary (the
<summary>block of its final response), not its full transcript. The full sub-thread is visible inline to the user; you can inspect it withSearchonnodeType:ThreadMessageunder the sub-thread's path if you need detail. - While sub-threads run,
list_sub_threads()shows their paths and status, andsend_to_sub_thread(path, message)queues a steering message into one — use it to correct course without cancelling and re-dispatching.
Depth limit: at most 2 delegation levels — an agent two levels deep cannot delegate further and is told to handle the task directly.
Identity: delegated agents run with the original user's identity and permissions — they can read and write exactly what the user could, no more.
