map-my-estate

map-my-estate is a skill for Claude Code from debabsah/analytics-office. It costs 171 tokens per session (1,994 once invoked), scanned A, original, MIT.

A way to draw a trustworthy picture of a data estate, such as an entity-relationship diagram or a flow from sources through transformations to reports.

In plain words
What is it for?
Use it to map existing data structures and lineage, showing evidence for each connection and leaving unsupported relationships visibly uncertain.
Why use it?
It prevents diagrams from presenting guessed tables, links, or data flows as facts.

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.

Security

Grade A, and why

map-my-estate 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 8d 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.

map-my-estate

The cartographer who only draws what the record can prove: every edge carries its citation, every guess renders as a guess, and the blank spots stay visibly blank.

When to use

Fire when the deliverable is a picture of what exists — an ER view (entities, keys, relationships) or a lineage/dataflow view (source → transform → consumer) — drawn from the knowledge base and whatever code/docs are on hand. Do NOT fire to BUILD the record (groundwork — this projects what it built), to design a FUTURE model (model-contract — its star is a design, this draws what is), to review code correctness (review-my-query), or to audit the record's claims (kb-reconcile). This draws; it does not orient, design, review, or audit.

The trap this exists to beat

Asked to "draw the ER diagram," a capable model produces a beautiful, complete, plausible graph — and that completeness is the failure. It fabricates edges: the join it assumed from column names (order_ref must point at ORDERS), the FK that nothing declares, the feed direction read off a stg_ prefix, the orphan table wired in because an island looks unfinished. A wrong diagram is worse than no diagram, because diagrams carry false authority — people stop checking what a picture asserts. This skill draws too, but an edge exists on the map only the way a claim exists in this bench: with its evidence cited — and the honest map of a thin record is mostly dashed, which is exactly the point.

The loop

  1. Scope gate (first move). Map WHAT — the spine of one metric, one mart, the whole estate? Pin the anchor and the view type (ER / lineage). Budget ~25 nodes per view; a big estate gets multiple views, never a hairball.
  2. Harvest the evidence. Read what the record holds: landscape.md (objects, connections, grain/keys), model-contract.md (only if BUILT — a design is not an as-is), query-review.md and any provided code (joins are evidence), kpi-contract.md (source-of-record edges), inputs/ artifacts. Note each candidate edge WITH its source.
  3. Grade every edge. Evidenced — an FK in DDL, a join in provided code, documented lineage, or an attributed owner statement. [unverified] — plausible but unsupported: name similarity, a prefix convention, "it probably feeds." Name-likeness is NEVER evidence. An island with no documented connections stays an island, labeled.
  4. Draw. Mermaid: erDiagram for ER, flowchart LR for lineage. Solid arrows for evidenced; dashed (-.->) + [unverified] for the rest; unknown/island nodes visibly marked ("no documented connection"). Each dashed edge is an interview question for groundwork.
  5. Write the edge ledger. Under each view: edge · kind (FK / join / feed / ownership) · evidence (file:line or verbatim cite) · status. The ledger is what makes the picture auditable.
  6. Stamp + emit. estate-map.md (template: references/estate-map.md) opens with its derived-from set (the files + dates it was projected from) so kb-reconcile can flag it stale when the record moves on. A fabricated-edge avoided (the plausible wiring you refused) gets its catches.md line. Then stop — refresh is just re-running this skill.
