Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00032 | $0.01492 |
| Opus 5.5 | $0.00013 | $0.00597 |
| Sonnet 5.5 | $0.00006 | $0.00298 |
| Haiku 4.5 | $0.00003 | $0.00149 |
Grade A, and why
spotfire-to-sigma 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 4d 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.
How it starts
The opening of the file, as written. The whole thing — 144 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Spotfire → Sigma
This foundation supports authoritative extraction, deterministic conversion,
Sigma POST/readback, and warehouse execution verification. It does not
claim Spotfire source parity. A normal live run stops at exit 16 after the
warehouse gate until rendered source-visual evidence is supplied.
Phase 0 — Assess (C1)
Use the sibling spotfire-assessment skill for estate inventory and
shortlisting. It accepts the same authoritative single-document manifest used
here. For one selected analysis, run scripts/scan_gaps.py or let the
orchestrator write gap-report.json.
Phase 1 — Discover (C2)
Export through the public Spotfire.Dxp.Application API:
OutputPath=/secure/export/spotfire-manifest.json
ProvenancePath=/secure/export/spotfire-manifest-provenance.json
SourceDxpPath=/secure/source/analysis.dxp
ExecutionContext=analyst
The manifest is authoritative only when authority.authoritative=true,
api_surface=Spotfire.Dxp.Application, and dxp_raw_used=false. Validate it:
python3 scripts/validate_manifest.py spotfire-manifest.json \
--provenance-map spotfire-manifest-provenance.json
spotfire-manifest-provenance.json is exporter API evidence. It is not the
warehouse map. Create a customer warehouse target map conforming to
refs/spotfire-source-map.schema.json; this maps imported, embedded,
on-demand, and data-function outputs to landed warehouse tables.
Dry-run may report an unavailable DXP hash, but live mode requires
SourceDxpPath so the manifest, resumed Sigma objects, and visual evidence are
bound to the exact source bytes.
Phase 1.5 — Reuse-check (C3)
The orchestrator writes workbook-signature.json and runs
find-or-pick-dm.rb. A safe auto-pick is read back and census-checked. An
ambiguous recommendation stops at exit 15; rerun with either
--reuse-dm <id> or --force-new-dm. Every decision is recorded in
dm-reuse-decision.json.
Phase 2 — Convert (C4)
convert.py consumes manifest v1 (model.tables, model.relations,
presentation.pages, presentation.filtering_schemes, automation, and
security). It translates supported formulas and visuals, preserves nested
layout, and emits loud gaps for unsupported scripts, data functions, mods,
markings, bookmarks, and security work.
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.

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.
- 4d ago First seen · 144 lines · 32 tokens per session scan A c78cb8293800
spotfire-to-sigma is a skill published in the GitHub repository twells89/sigma-migration-skills (17 stars, last pushed yesterday), licensed MIT. It adds 32 tokens to every session and 1,492 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-10-14.
