Bi Measure Builder is an agent skill from OneWave-AI/claude-skills. Writes, explains, debugs, and optimizes BI calculations - Power BI / Fabric DAX measures and calculated columns, Tableau calculated fields (FIXED/INCLUDE/EXCLUDE LOD expressions, table calculations), and Looker LookML measures, dimensions, and derived tables. Use it whenever the request involves DAX, CALCULATE, a Power BI measure, a Tableau calc or LOD, LookML, or a business metric such as YoY, YTD, rolling 12 months, running total, percent of total, distinct customers, ranking, new vs returning customers…
Its SKILL.md is about 2.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 31 other files, including scripts and reference files (for example `examples/worked-example.md`, `examples/yoy_spec.json` and `references/dax.md`).
It sits in Data & Analytics. It works with Tableau and Power BI. The repository describes itself as: 200+ production-ready Claude Code skills for sales, marketing, design, engineering, and AI agent architecture. Built and maintained by OneWave AI. The licence is MIT.
7 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit fc5b785. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

Ships 1 file in scripts/ (Python, from the files we listed), which the agent can run.

No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Bi Measure Builder loads about 2.2k tokens when it runs, and up to ~9.1k if it reads all its reference files. Until then it costs about 238 tokens; SKILL.md has 1,067 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

|---|---|---|
| CALCULATE boolean filter replaces the existing filter on that column | "Blue sales" shows the same number on every color row | Wrap in KEEPFILTERS(...) to intersect instead of overwrite, when the intent is "within the current selection" |
Filtering a whole table in CALCULATE (FILTER(Sales, ...)) | Wrong numbers via expanded-table intersection; very slow | Filter columns: KEEPFILTERS(Sales[Qty] * Sales[Price] >= 500) |
| Context transition surprise | Measure referenced inside SUMX/FILTER/calculated column gives per-row results or double counts duplicate rows | Know that a measure reference is an implicit CALCULATE; iterate a unique key (VALUES(Table[Key])), not a table with duplicate rows |
| Aggregator where an iterator is needed | SUM(Sales[Qty]) * SUM(Sales[Price]) is wrong | SUMX(Sales, Sales[Qty] * Sales[Price]) |
| Non-additive total "fixed" by summing | Distinct count or % total "doesn't add up" | Usually correct as-is. Only if the business wants a visual total: SUMX(VALUES(dim[key]), [Measure]) |
| Time intelligence without a proper date table | Blank or wrong YoY/YTD, errors on gaps | Classic DAX: contiguous date table marked as date table, relationship from it to the fact. Calendar-based: define a calendar. Never use the fact's own date column |
| BLANK vs 0 | Visual explodes to every customer; = 0 tests misfire | Return BLANK when there is nothing meaningful (DIVIDE without the 3rd arg); test with ISBLANK or ==, since BLANK() = 0 is TRUE |
| Bidirectional relationships as a shortcut | Ambiguity, slow, confusing slicers | Single-direction model; enable CROSSFILTER(..., BOTH) inside the one measure that needs it |
| Tableau FIXED ignores the dimension filter | LOD total unchanged when user filters | FIXED runs before dimension filters: add the filter to context, or use INCLUDE/EXCLUDE (run after dimension filters) |
| Tableau table calc sees only what is in the view | YoY blank for first year, rolling window truncated after filtering | Filter with a table-calc filter (runs after the calc) instead of a dimension filter; densify missing dates |
| Tableau total vs COUNTD / averages | Grand total differs from the row sum | "Automatic" totals re-aggregate underlying data (usually right); "Total Using: Sum" sums what is visible |
| Looker fanout on one-to-many joins | Sums inflated after adding a joined view | Set primary_key: yes on every view and a correct relationship:; Looker then applies symmetric aggregates. For denormalized tables use sum_distinct + sql_distinct_key |
| Looker post-SQL measures | running_total / percent_of_total wrong, null, or unfilterable | They compute after the query on returned rows only: row limits break them, they cannot be filtered or referenced by other measures. Move logic to SQL (derived table + window function) when it must be exact |
Looker filters: on type: number | Filter silently not applied | Put filters: on the component sum/count measures, then combine them in the type: number measure |
scripts/measure_check.py is an independent oracle (pandas). Give it the user's sample CSV and a JSON spec; it prints the expected value for every visual row and for the total, evaluated the way BI tools do (total recomputed in its own context, time calcs reading outside the slicer range, empty = BLANK). With --actual it diffs against what the tool shows and exits 1 on mismatch.
python scripts/measure_check.py --data sample.csv --spec spec.json [--actual tool_output.csv] [--json]Spec fields: calc (sum, count_rows, distinct_count, prior_year, yoy_delta, yoy_pct, ytd, running_total, rolling, new_customers, returning_customers, last_balance, pct_of_total, rank), date_column, value_column, key_column (customer/entity/distinct key), group_column (for pct/rank), grain (day|month|quarter|year), range ({start, end} = report date filter), filters ({column: [values]}), params (window, fiscal_year_start_month, ties: skip|dense, order, mode: per_entity|global_last_date). Examples of every calc: tests/specs/. Self-test: python tests/test_measure_check.py.
When the user has no sample, build a 5-10 row one that exercises the edge that matters (a missing month, a customer with no prior purchase, an entity without an end-of-month snapshot) and show it.

Going by SKILL.md and its folder, Bi Measure Builder needs Python for the scripts in its folder and the command-line tools its instructions call (python). Our summary lists: Python 3.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
Bi Measure Builder is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 2.2k tokens (SKILL.md is roughly 8.8k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 6.9k tokens, read only when the agent opens those files.
Skills that share tags, products or a category with Bi Measure Builder: Chart Selector (revfactory/harness-100, 1.3k stars), Power Bi AI Readiness (DKH-DK/Self-Service-Power-BI-Fabric, 113 stars), Pbi Report Builder (lukasreese/powerbi-claude-skills, 129 stars) and Pbi Doc (xperiun/skills-xperiun-free, 116 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
