What is microstrategy-to-sigma?

A skill for migrating MicroStrategy dossiers, reports, and classic semantic models into Sigma. It extracts the source content through the MicroStrategy API, converts it, and builds Sigma data models and workbooks.

Use it when moving MicroStrategy content to Sigma: authenticate to MicroStrategy, extract the model and reports, generate the Sigma specifications, validate them, and verify that real report results match.

It provides a controlled conversion path with validation and result comparison, helping prevent empty or unverified workbooks from being delivered.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

Clone the repo

git clone --depth 1 https://github.com/twells89/sigma-migration-skills

npx agentmods add skills/twells89/sigma-migration-skills/microstrategy-to-sigma

Made for: Claude Code.

Or install microstrategy-to-sigma, the plugin that ships this one along with the rest of its 2 skills.

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	$0.00107	$0.08585
Opus 5	$0.00053	$0.04293
Sonnet 5	$0.00021	$0.01717
Haiku 4.5	$0.00011	$0.00859

Security

Grade B, and why

microstrategy-to-sigma scanned grade B with 2 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 12d ago.

The scan reads SKILL.md. This mod also ships 28 executable files (fixtures/build_schema.py, scripts/assert-phase6-ran.rb, scripts/bootstrap.ps1, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

How it starts

The opening of the file, as written. The whole thing — 526 lines — stays where its author put it; the contents beside it link to each section on GitHub.

MicroStrategy → Sigma migration

Windows / first run — run the environment doctor before anything else: bash scripts/doctor.sh (macOS/Linux/Git Bash) or powershell -ExecutionPolicy Bypass -File scripts\doctor.ps1 (Windows). It checks Ruby/Python/Node/bash and flags the Python "Store stub" + CRLF with exact fixes. Details: refs/environment.md.

⛔ THE ONE PATH (do not ship an unverified/empty workbook)

Convert with convert.py, POST its specs, then verify with verify_parity.py. Rules:

NEVER hand-author a DM/workbook JSON and curl-POST it, and never ship empty "placeholder" pages. Post only what convert.py produces. If MicroStrategy is unreachable (no session), STOP and tell the user to authenticate — don't build a shell.

verify_parity.py must be GREEN with REAL reports before you're done. It now refuses a vacuous pass — an expected_parity.json with 0 reports is "NOT parity-clean" (exit 1), never a silent green. An empty/placeholder workbook is never done.

Preflight the workbook spec before POST (mandatory)

Before POSTing any workbook spec, run both validators:

ruby scripts/lib/preflight_lint.rb <spec.json> catches grouping and control grammar failures.
From the companion sigma-workbooks skill, run ./scripts/validate-spec.sh <absolute-spec-path> to reject bare source-column self-references and list/segmented controls without a value-list source.

The API accepts a filters-only list control, but the picker is empty: filters names what changes; source supplies the values a user can select. API acceptance is not a shipping criterion. Date-range controls are different and correctly use filters without a separate value-list source. Fix every violation first — never POST past it, and never conclude a feature is "unsupported" from an Invalid kind error (it means the inner fields are wrong). Verified shapes: sigma-workbooks controls.md / tables.md.

What ships with it

60 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

microstrategy-to-sigma is a skill published in the GitHub repository twells89/sigma-migration-skills (16 stars, last pushed yesterday), licensed MIT. It adds 107 tokens to every session and 8,585 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it B with 2 findings (reads agent configuration directories, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
