Access Matrix

What it is: What each role can see and change.

Overview

Works out the smallest useful Access Matrix setup for the business in front of it, then

builds it only when asked. The default output is a short recommendation, not a

spreadsheet. Artifacts - CSV, SQL DDL, JSON Schema, Notion mapping - are produced on

request, from one field list so they cannot drift apart.

Layer: Layer 1: Foundation. Fits: Growth stage. Table code: n/a.

When to Use This Skill

• who can access what matrix
• role permission matrix
• access control spreadsheet
• who sees which data

Also use it when the user says "what each role can see and change", or describes the same process happening in a

spreadsheet, a document or someone inboxes.

Do not use it for: payroll calculation, tax filing, or legal advice. This skill produces

empty templates only - it never holds or processes real employee or customer data.

How It Works

Follow the shared execution contract. The module-specific rules below define only domain fields, decisions, calculations, and safety constraints.

Step 1 - Identify intent

Read the request and pick the intent before asking anything.

• "set up" or "build" or "create" -> the user wants artifacts; go to Step 2.
• "our process is ..." or "it is in a sheet" -> the user wants to move an existing process; capture it, then Step 2.
• "is this right" or "review" or "audit" -> the user wants a check, not a build; answer from what they share.
• "how do I ..." -> advice question; answer directly and offer the build only if it helps.

Ask only if this is the highest-value missing fact; otherwise proceed without an opener:

Q: How many roles exist in the company?

Step 2 - Ask only what is missing

Skip anything the user already answered, in any earlier message. Ask the rest one at a

time, and stop as soon as the remaining answers would not change the output.

• Scope - Which system or data? / How many roles? / Any external people?
• Roles - Who is owner or CEO? / Who is admin? / Who is line manager?
• Rules - View only or edit? / Any confidential areas? / Reviewed how often?
• Current process - How do you track access now? / Spreadsheet or none? / Any known gaps?
• Outcome - What should this produce? / An access list or a review cycle?

Never invent an answer. If the user does not know, record it as unknown and carry on.

Step 3 - Hold the internal context

Hold the answers in this shape. It stays internal - it is not shown to the user unless

they ask, and it never carries a value the user did not give.

module: access-matrix
intent: null            # setup | advice | review | fix | build | convert | export
scale: null             # Starter | Growth | Scale, only if the answer changes it
areas:
  "Scope": null
  "Roles": null
  "Rules": null
  "Current process": null
  "Outcome": null
requested_outputs: []   # csv | sql | json | notion | xlsx - requested formats only
confirmed_facts: []     # only what the user actually said
open_questions: []      # the unanswered ones, in the order worth asking

Step 4 - Recommend the smallest workflow

If an artifact was requested, build it after resolving essential missing facts. Otherwise give a short recommendation and offer the relevant artifact.

Recommended approach: Keep the matrix in the tool the team already reviews in, and treat it as a recurring review rather than a one-time document.

Why this one: Access problems are rarely about storage. They are about nobody re-checking who still needs what, so a review cycle matters more than the matrix itself.

Workflow: Role list → System inventory → Access rows → Quarterly review → Removal

Step 5 - Build only on request

Once the user asks for it, derive the fields from the confirmed context and emit the

requested artifacts. For machine-readable text, keep prose outside the data; for files,

provide a usable link. Report material validation failures or limitations separately.

**A selected Notion output is rendered by notion-manual-import, so route the

Notion step there.** When the user selects Notion, hand that step to

@notion-manual-import: it holds the CSV, the property

mapping, the import steps and the verification checklist, and it renders the Field

Reference below instead of defining a table of its own. Do not restate the mapping

here and do not improvise the import steps. Manual CSV and mapping outputs need no

connection. For requested workspace changes, follow the shared contract: verify actual

tool access and the target before writing. A user saying "connected" is not tool evidence.

Never ask for a Notion password or token.

For an Excel-compatible CSV, use UTF-8 with a byte order mark so Excel opens the

text correctly. A CSV is not an .xlsx workbook; create .xlsx only when the user

requests a workbook.

A CSV carries no types, so after it, name the columns

that need a number, date or currency format applied.

Examples

Prompt

We have 6 roles and want to know who can see payroll and bank details.

Context first - one question per message, nothing already answered:

Q: Which system?

A: Payroll, bank details and HR records.

Q: How often should it be reviewed?

A: Every quarter.

Q: What do you use today?

A: Nothing tracked.

Recommended next step - offered, not built:

Keep the matrix in the tool the team already reviews in, and treat it as a recurring review rather than a one-time document.

Workflow: Role list → System inventory → Access rows → Quarterly review → Removal

Want the CSV, SQL, JSON Schema and Notion mapping for this?

Best Practices

• Build when requested; recommend and offer a build for advice-only requests.
• One question per message. A batched intake reads as a form and gets guessed at.
• Keep display names identical across CSV and JSON; document normalized SQL identifiers.
• Use relation for anything that points at another table, text only for free text.
• Money fields are currency, never text. Dates are date, never free text.
• If the user requests an example row, keep it obviously fake so nobody imports it as real data.

Limitations

• Empty template only. It does not compute payroll, tax, leave balances or KPIs.
• Notion relations need both databases imported before the link column resolves.
• Select options are a starting set. Rename them to match how the business talks.
• No automation, reminders or sync. Those need the integration layer.
• Does not provision or revoke access. It only records who should have what.
• Legal, tax and HR review is still required before this drives real decisions.

Security & Safety Notes

• Never fill in real names, salaries, medical or banking data. Placeholders only.
• Label example rows as synthetic, and keep bank details masked.
• Local reads, generation commands, and validation are part of a requested artifact build.

External writes, messages, provisioning, and publication require authorization for that

action and target; existing explicit authorization does not need to be repeated.

• If sensitive data is supplied, avoid repeating unnecessary identifiers. Use only what

the requested review needs; keep generated templates empty. Do not claim deletion

from the conversation or service storage.

• Privacy, legal and disciplinary cases need a qualified human reviewer before anything

is acted on.

Common Pitfalls

• Problem: a static mapping is described as a completed workspace build.

Solution: deliver manual mappings without a connection; claim a live change only

after the authorized tool operation succeeds.

• Problem: asked all six questions in one message.

Solution: ask one, wait, and drop any the first answer already covered.

• Problem: built a full system when one table was asked for.

Solution: build what was requested; mention the parent skill separately.

• Problem: all four artifacts drift apart.

Solution: derive all four from the field list in this file, never by hand.

• Problem: Notion import shows every column as Text.

Solution: that is expected. Apply the property mapping table once, after import.

Reusable Prompt

I want to set up what each role can see and change for my company.
Ask me one short question at a time, and only about what I have not already told you.
Then recommend the smallest setup that fits, and wait for me to ask before you build it.
When I ask, output CSV, SQL DDL, JSON Schema, a Notion property mapping or an Excel workbook. Data only.
