What is model-power-bi?

A skill for editing a Power BI semantic model—the data structure behind reports—using TMDL text files. It handles DAX calculations, columns, relationships, calculation groups, and dependency lineage.

Use it to inspect a model, create or update single or multiple DAX measures, manage relationships, trace what depends on a measure, and safely preview or perform deletions.

It helps change the model without accidentally altering unrelated data partitions, annotations, or source queries. It also checks dependencies before measures are changed or removed.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00100	$0.01143
Opus 5.5	$0.00040	$0.00457
Sonnet 5.5	$0.00020	$0.00229

Security

Grade A, and why

model-power-bi scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Work with the Power BI Model (TMDL)

The pbi-model server edits the semantic model in a .pbip as surgical, loss-free text edits — partitions, annotations, and M source are never touched. Call pbi_set_project(path) first.

Read before you write

pbi_get_model() — tables, columns, measures, relationships.
pbi_list_measures(table?) — measures with DAX + format.
pbi_model_lineage(measure?) — the dependency graph: what a measure depends on AND what depends on it (direct + transitive). Use this before any delete or refactor.

Measures

pbi_create_measure(table, name, dax, format?, display_folder?) — name must be unique model-wide (enforced).
pbi_update_measure(table, name, dax?, format?, display_folder?) — partial; omitted fields are preserved.
pbi_bulk_create_measures(measures[]) — create many at once; the whole batch is validated before any write. Use this when the user pastes a list of measures — one call, not N.
pbi_delete_measure(table, name, force?, dry_run?) — refuses if other measures OR report visuals/filters depend on it. Use dry_run=true to preview, force=true only when the user confirms.

Columns, relationships, calc groups

pbi_create_column(table, name, data_type, summarize_by?, source_column?, dax?) — pass dax for a calculated column.
pbi_create_relationship(from_table, from_column, to_table, to_column, ...) — both endpoint columns must exist; duplicates are rejected.
pbi_create_calc_group(name, precedence, items) — items are [{"name": "YTD", "dax": "..."}] using SELECTEDMEASURE(). Great for time-intelligence patterns applied across all measures.

Auditing

pbi_model_usage() (report server) classifies every field as direct / indirect / unused — the safe basis for cleanup.
pbi_profile_model() classifies fact/dimension/date tables and measure roles (ratio/currency/time-intelligence) — useful context before building.
