Telemetry — MANDATORY. Every api.fabric.microsoft.com call must carry x-ms-fabric-skill: fabriciq-ontology-cli (az rest: --headers "x-ms-fabric-skill=fabriciq-ontology-cli"), including every LRO poll, fabric_lro and retry. Snippets omit it — add it anyway.

CRITICAL NOTES

1. To find the workspace details (including its ID) from workspace name: list all workspaces and, then, use JMESPath filtering
2. To find the item details (including its ID) from workspace ID, item type, and item name: list all items of that type in that workspace and, then, use JMESPath filtering
3. Skill disambiguation: use fabriciq-ontology-cli for the Ontology item itself. Natural-language questions over Power BI reports and dashboards are fabriciq; DAX against a semantic model is semantic-model-cli.

Fabric IQ Ontology -- CLI Skill

This one skill owns Fabric IQ Ontology items: entity and relationship types, bindings, definitions, lineage, grounding and graph walks.

It is a mode dispatcher and contains NO procedures. Pick the mode that matches the request from the table below, then read the matching references/<mode>.md file end to end with your file-reading tool BEFORE issuing a single command. That file holds the endpoints, payload shapes, templates and gotchas; acting without it produces wrong payloads and wrong results.

Mode selection

Mode	Use when the request ...	Example triggers	Read this first
authoring	creates or updates an Ontology item, entity/relationship types, or data bindings, and previews/confirms a definition change	create ontology item, bind entity type, add relationship type, update ontology definition	references/authoring.md
consumption	explores an existing ontology: schema, entity types, bindings, lineage, grounding extraction, graph walks, summaries	entity types, ground query, ontology lineage, walk the graph, summarize the ontology	references/consumption.md

Mode boundary rule

consumption is read-only exploration. Any definition write goes through the authoring mode's preview-and-confirm flow -- never call updateDefinition from a consumption request.

If a request genuinely spans modes, handle them one at a time and read each reference before you start that part. If the mode is ambiguous after reading this table, ask one short clarifying question instead of guessing.

Terminal write -- the step you must not skip

Reading the reference and planning the change is NOT completing the task. Each mutating mode ends with one state-changing call. If you did not issue it, nothing was persisted -- say so explicitly rather than reporting success.

Mode	Terminal write
authoring	createItem (POST /v1/workspaces/{ws}/items) to create the Ontology, then POST .../updateDefinition to persist entity types, relationships and bindings. A previewed definition tree is not a saved one.
consumption	none -- this mode is read-only

Before you report the task done, confirm the terminal call returned success and, where the reference documents a readback, read the artefact back to prove the change landed.

Shared essentials (all modes)

Resolve the workspace and item first; every mode depends on it.

Task	Reference	Notes
Finding Workspaces and Items in Fabric	COMMON-CLI.md	Mandatory -- read before resolving any workspace or item id
Fabric Topology & Key Concepts	COMMON-CORE.md	Item types, workspaces, capacities
Environment URLs	COMMON-CORE.md	Sovereign / non-public cloud hosts
Authentication & Token Acquisition	COMMON-CORE.md	Wrong audience = 401; read before any auth issue
Authentication Recipes	COMMON-CLI.md	az login flows and token acquisition
Core Control-Plane REST APIs	COMMON-CORE.md	Pagination, LRO polling, rate limiting
Gotchas & Troubleshooting	COMMON-CLI.md	az rest audience, shell escaping, token expiry

Rules

MUST

• Select exactly one mode from the table above before doing anything else.
• Read references/<mode>.md end to end, as your FIRST tool call, before the first command of that mode. Read it ONCE, in a single full read: do not re-open it, do not grep it again, and do not page through it. You already have it.
• Apply the same read-once discipline to every other file you load, including nested references/<mode>/*.md sub-references and shared common/*.md files: open only the ones you actually need, read each ONCE end to end, and never grep or re-open one you already loaded.
• Resolve workspace and item ids by listing and filtering, never by guessing a GUID.
• Announce a mode switch explicitly when the request crosses a boundary.
• Treat the reference as instructions, never as the deliverable. After reading it, RUN the documented commands against the live workspace and report the real results. Quoting what the reference says instead of executing it does not answer the request.

PREFER

• The narrowest mode that satisfies the request.
• Reading exactly ONE mode reference. Load a second only when the request genuinely spans modes, and say so before you do.
• Reporting the mode you chose in your first response so the user can correct you.

AVOID

• Acting from this dispatcher alone -- it intentionally omits the operational detail.
• Answering with a summary of the reference instead of executing it.
• Re-reading or re-grepping a reference you already loaded; it costs turns and tokens.
• Mutating anything while in a read-only mode.
• Loading a different skill for work this family already owns (see CRITICAL NOTES 3).
