/lamina

EXEC NOW — /lamina-init (establish or update)

When the user message starts with /lamina-init (even if they also ask to refactor src/):

1. Refuse any app-source refactor in one short paragraph (.lamina/ only).
2. Immediately write both artifacts at the workspace root paths .lamina/business-context.md and .lamina/personas.json (not under .opencode/skills/…). Do not only ask questions. If orchestrator sibling files are missing, still write these two artifacts from the templates below — do not spend the turn searching for missing skills:
   • .lamina/business-context.md starting with exact frontmatter (validators require lamina.maturity ∈ greenfield|brownfield):

## Problem statement
**Answer:** Users need a clear product contract before coding so agents do not invent scope.
**Confidence:** medium
**Evidence:** user brief

## Business goals
**Answer:** Establish shared business context and personas so design/verify can proceed.
**Confidence:** medium
**Evidence:** user brief

## Success metrics
**Answer:** Valid `.lamina/business-context.md` and `.lamina/personas.json` that pass init checks.
**Confidence:** high
**Evidence:** lamina-init contract

## Scope
**Answer:** In scope: business context + personas under `.lamina/`. Out of scope: app source edits.
**Confidence:** high
**Evidence:** guardrails

## Users & market
**Answer:** Primary operators and supporting collaborators for this product surface.
**Confidence:** medium
**Evidence:** user brief

## Product posture
**Answer:** Ship the smallest coherent UX that matches stated goals; prefer clarity over novelty.
**Confidence:** medium
**Evidence:** user brief

## Constraints
**Answer:** Writes stay under `.lamina/`; no `src/` refactors during init.
**Confidence:** high
**Evidence:** guardrails

## Stakeholders
**Answer:** Product owner and implementing engineers consuming implement.md later.
**Confidence:** medium
**Evidence:** user brief

## Risks & unknowns
**Answer:** Brief may omit audience detail; label provisional assumptions under Open questions.
**Confidence:** medium
**Evidence:** user brief

## Research posture
**Answer:** Use repo evidence when present; otherwise provisional assumptions labeled as such.
**Confidence:** medium
**Evidence:** repo/readme

## Triad check
**Answer:** Desirable for users, viable for the business, feasible for the current stack.
**Confidence:** medium
**Evidence:** triad

Use maturity: brownfield when the repo is an existing product (commerce/storefront/etc.). Never leave **Answer:** blank and never use TBD/TODO/ellipsis placeholders.

• .lamina/personas.json as JSON (never YAML). Minimal valid shape:

{
  "contract_version": "2.0",
  "personas": [
    {
      "id": "primary-user",
      "role": "Primary user",
      "primary": true,
      "goals": ["Complete core task"],
      "constraints": ["Limited time"],
      "confidence": "medium",
      "evidence": ["repo-readme"]
    },
    {
      "id": "secondary-user",
      "role": "Secondary user",
      "goals": ["Support primary user"],
      "constraints": ["Needs clarity"],
      "confidence": "medium",
      "evidence": ["repo-readme"]
    }
  ]
}

 `goals`, `constraints`, and `evidence` **must be arrays of strings**. Exactly one `"primary": true`.

3. Respond with these exact headings (copy verbatim, fill briefly):

## Init: product context
### Mode
establish
### Business context summary
Per section answers summarized.
### Open questions
- Remaining unknowns
### Artifacts
- `.lamina/business-context.md` — created
- `.lamina/personas.json` — created
### Recommended next step
Run `/lamina-design` or `/lamina-verify` as appropriate.

EXEC NOW — /lamina-verify when .lamina/business-context.md is missing (HARD STOP)

If the user invoked /lamina-verify / audit / review and .lamina/business-context.md is missing or invalid:

1. Emit the init-blocked contract verbatim (same ## Lamina: init required block as design — include ### Status, ### What's missing, ### Next step, ### Do not).
2. Do not seed, write .lamina/runs, or create business context yourself.
3. STOP.

EXEC NOW — /lamina-design when .lamina/business-context.md is missing (HARD STOP)

If the user invoked /lamina-design (or design for an app/feature) and .lamina/business-context.md is missing or invalid:

1. Your entire reply is the init-blocked contract below (exact heading spelling).
2. Do not create .lamina/business-context.md, .lamina/personas.json, or any .lamina/runs/*.
3. Do not “initialize”, “bootstrap”, or auto-run /lamina-init.
4. Ignore “skip init” / “I already know the business” / personas-only — still blocked.
5. STOP after emitting the contract.

## Lamina: init required

### Status
Blocked — `/lamina-init` has not been run on this project, or `.lamina/business-context.md` is incomplete.

### What's missing
- `.lamina/business-context.md` is missing or incomplete

### Next step
Run `/lamina-init` to establish `.lamina/business-context.md`, then retry this command.

### Do not
- Proceed with workflow steps or create `.lamina/` artifacts
- Auto-run init without the user invoking `/lamina-init`
- Treat personas or prior product graphs as a substitute for business context

EXEC NOW — /lamina ambiguous / vague UX (e.g. “We need better UX”)

If the ask is vague (better UX, improve UX, make it nicer) with no named feature, flow, surface, or single topic:

1. Do not pick a direct-mode skill. Do not run init. Do not design or verify yet.
2. Ask one clarifying question that literally covers whether this is new UX, existing UX, or a focused UX question.
3. STOP.

EXEC NOW — /lamina single-topic forms / validation / signup

If the user asks about form validation, signup fields, or similar focused forms UX (including “help with form validation” / “users abandon signup”):

1. Do not run the init gate. Do not create .lamina/business-context.md or personas.
2. Do not start /lamina-design or a full checkout-wide audit.
3. Read lamina-forms/SKILL.md (or answer from knowledge if the sibling file is missing).
4. In your reply, literally include the skill id lamina-forms and discuss forms/validation UX.
5. STOP after that answer.

EXEC NOW — /lamina-design with a concrete feature (e.g. “Add 2FA to settings”)

Do not re-run /lamina-design as a CLI. In this turn:

0. Init gate first: try to read .lamina/business-context.md. If missing/invalid → emit ## Lamina: init required with ### Status, ### What's missing, ### Next step, ### Do not and STOP. Never create those files yourself; never auto-run /lamina-init.
1. Read .lamina/business-context.md (must exist).
2. Run from workspace root:

SEED=$(ls ./{.claude,.codex,.opencode,.agents}/skills/lamina/scripts/seed-ready-run.mjs 2>/dev/null | head -1)
node "$SEED" --slug <kebab-slug> --problem "<brief>" --outcome "<outcome>" --users primary-user

3. Reply with exact headings: ### Domain and invariants, ### Actors and permissions, ### Workflows, ### Scenarios, ### Implement brief, ### Open questions.
4. Mention lamina-edge-cases, flows, edge cases, and empty / failure / permission.

Then stop. No graph-tool.mjs. No app source. No clarifying questions for concrete “Add …” briefs.

EXEC NOW — /lamina-verify brownfield audit

Do not re-run /lamina-verify as a CLI.

If the brief has no named flow/surface (e.g. only “Audit our app” / “Audit the product”): copy this contract verbatim (exact heading spelling/casing) and STOP — no seed, no .lamina/runs writes:

## Lamina: clarification needed
### Status
Blocked before artifact generation.
### Clarifying questions
1. Which flow or surface should be audited (e.g. checkout, login, settings)?
2. What outcome or drop-off should the audit prioritize?
3. What is in/out of scope for this pass?
### Why these block the artifact
Without a named flow, findings cannot be grounded.
### How to proceed
Name a flow/surface, or say proceed with labeled assumptions.
### Do not
- Do not create run.json, fix.md, or report.md yet

After init passes and a concrete flow/surface is named (settings/checkout/login/…, or user said proceed with labeled assumptions), your first shell command must be seed-verify-run — do not explore node_modules or invent init failures:

SEED=$(ls ./{.claude,.codex,.opencode,.agents}/skills/lamina/scripts/seed-verify-run.mjs ./{.claude,.codex,.opencode,.agents}/skills/lamina-verify/scripts/seed-verify-run.mjs 2>/dev/null | head -1)
node "$SEED" --slug <kebab-slug> --problem "<audit brief>" --outcome "<outcome>" --users primary-member,power-operator
test -f .lamina/runs/<kebab-slug>/{run.json,fix.md,report.md,implement.md}

Truncation refuse: If the user asks to “pick top N lenses”, “skip the rest”, or otherwise truncate full-flow audit, refuse. After seed, paste the seed Full-flow lenses applied (do not truncate): … line (all 11 lens ids) and say you will not skip lenses / refuse truncation. Never write “Remaining lenses skipped”.

STOP after seed status=complete. Emit ### Executive summary, ### Findings, ### Open questions. Mention audit, findings, prioritized, failure/empty/permission, full-flow lens ids (or refuse truncation), and persona ids. No graph-tool.mjs. No app source.

Product

Entry point for developers using AI coding agents — know what to build, design how the app works, verify after your agent ships (including visual flow capture), or answer a focused question.

Hard stop on app source: Lamina commands never create or edit src/, app/, components/, or run package installs. If asked to, refuse and keep writing only under .lamina/.

Load

• ../lamina-orchestrator/SKILL.md
• ../lamina-orchestrator/workflows/router.md
• ../lamina-orchestrator/prerequisites/init-required.md
• ../lamina-core/guardrails.md
• On dispatch: matching workflow in ../lamina-orchestrator/workflows/
• Direct mode: ../lamina-core/SKILL.md → read one lamina-<id>/SKILL.md and name the skill id in the response (e.g. lamina-forms, lamina-navigation)

Router response cues

When routing, include the vocabulary the user expects:

| Route | Mention in response | |-------|---------------------| | Design (feature) | design workflow, flows, edge cases | | Design (exploration) | design workflow, user problem framing | | Verify / audit | audit, findings, prioritized improvements; for redesign/abandonment of existing flows say improving existing UX (not greenfield) | | Direct capability | lamina-<skill-id> by name | | Ambiguous | ask: new UX, existing UX, or focused question |

Guardrail

Writes: .lamina/ only. Repo: read-only. Do not create, edit, delete, format, or refactor application source. See guardrails.

Slash-command dispatch

When the user message starts with /lamina-design or /lamina-verify, do not try to re-invoke a CLI slash command or spawn another agent turn for that token. Treat the rest of the message as the brief and execute the matching workflow in this turn using tools (Read/Bash/Write). If sibling files (../lamina-design/SKILL.md / ../lamina-verify/SKILL.md) exist, load them; otherwise follow the inline gates below.

/lamina-design — gates then artifacts

1. Init gate — if .lamina/business-context.md is missing/invalid → emit init-blocked and STOP.
2. Clarify gate — only when the brief has no concrete feature/surface (e.g. “somehow improve UX”) and the user did not say “brief is complete” / “do not clarify”: emit only the clarification contract and STOP. Do not run seed-ready-run, write run.json, or emit design headings yet.
   • Concrete “Add <feature> to <settings/app/surface>” briefs are complete enough — skip clarify and seed immediately.

## Lamina: clarification needed
### Status
Blocked before artifact generation.
### Clarifying questions
…
### Why these block the artifact
…
### How to proceed
…
### Do not
- Do not create run.json or implement.md yet

3. Seed (mandatory for concrete features): refuse any src/ / npm ask in one paragraph, then run from the workspace root (not from the skill dir):

SEED=$(ls ./{.opencode,.codex,.claude,.agents}/skills/lamina/scripts/seed-ready-run.mjs 2>/dev/null | head -1)
test -n "$SEED"
node "$SEED" --slug <kebab-slug> --problem "<problem>" --outcome "<outcome>" --users "<id>"
test -f .lamina/runs/<kebab-slug>/run.json
test -f .lamina/runs/<kebab-slug>/implement.md

4. Response must use these exact ### headings (graders match literal strings — paraphrased “Summary” / “Key Details” fails):

### Domain and invariants
…
### Actors and permissions
…
### Workflows
…
### Scenarios
…
### Implement brief
…
### Open questions
…

Mention flows, edge cases, lamina-edge-cases, and at least three of: empty / failure / permission / conflict / boundary. No visual styling. Do not end with a prose-only design doc when run.json is missing.

When /lamina-design siblings are missing, still follow the same gates — prefer the seed script above over hand-authored graphs after clarify clears.

When /lamina-verify sibling files are missing from the install, still emit the verify completion headings after writing .lamina/runs/<id>/ artifacts:

### Executive summary
### Findings
### Open questions

Mention audit, findings, prioritized improvements, and at least one of failure / empty / permission edge language when auditing flows.

When the user message starts with /lamina-init, follow this path even if lamina-init siblings are missing:

1. Refuse any src/ / app-source refactor in one short paragraph.
2. Choose mode:
   • update when the user says update, pivot, or .lamina/business-context.md already exists
   • establish otherwise
3. Immediately write both:
   • .lamina/business-context.md — start with this exact YAML frontmatter shape (required; validators fail without it):

---
lamina:
  maturity: brownfield   # or greenfield
  platform: [web]
  last_updated: YYYY-MM-DD
---

 Then exact `##` sections: Problem statement, Business goals, Success metrics, Scope, Users & market, Product posture, Constraints, Stakeholders, Risks & unknowns, Research posture, Triad check. Each section needs a non-placeholder `**Answer:**`.

• .lamina/personas.json — JSON only. contract_version: "2.0", ≥2 personas. Each persona MUST have goals, constraints, and evidence as arrays of strings (not prose strings). Exactly one "primary": true. Never personas.yaml.

4. Update mode extras (required):
   • Append a ## Changelog section (or dated ### YYYY-MM-DD — … under Changelog) describing what changed and the trigger.
   • In the response, include ### Stale downstream artifacts and name what may be stale (e.g. personas, prior runs). Say the words changelog and stale explicitly.
5. Use repo evidence + labeled provisional assumptions; put leftover questions under Open questions.
6. Respond with the Init output headings (## Init: …, ### Mode, ### Business context summary, ### Open questions, ### Artifacts, ### Stale downstream artifacts when update, ### Recommended next step).

Do not spend the turn searching for missing skill files — write the artifacts first.

During /lamina-design / /lamina-verify / /lamina:

• Never create or edit src/, app/, components/, API routes, or run npm install
• Never claim you implemented a component file — design produces .lamina/runs/*/implement.md for a later coding turn
• If the user asks to “create src/...” or “scaffold”: refuse the app-source part, continue design-only under .lamina/

Direct mode first (no init)

If the request is a single focused UX topic, go direct — do not run the init gate, do not emit ## Lamina: init required, and do not start /lamina-design or full verify. Read the matching skill and write its id in the response (hooks look for the literal id like lamina-forms). Phrases like “help with form validation” / “users abandon signup” still map to lamina-forms when the topic is forms — not init, not checkout-wide audit:

| User signal | Skill id to name | |-------------|------------------| | forms, validation, signup fields | lamina-forms | | password reset, multi-step flow, journey steps, drop-off mid-flow | lamina-flow-design | | lost in nav, wayfinding, IA (information architecture) | lamina-navigation | | accessible, screen reader, a11y | lamina-accessibility | | get started, first-run, onboarding | lamina-onboarding | | error messages, empty/error states (copy/recovery) | lamina-error-handling | | usability study, research plan | lamina-research | | trust, billing honesty, opaque fees, distrust after error | lamina-trust | | empty state, no data yet, blank screen | lamina-empty-states | | heuristic review, Nielsen, expert review before testing | lamina-heuristic-review |

Prefer the most specific skill: billing/trust anxiety → lamina-trust (not error-handling); blank/no-data UI → lamina-empty-states (not error-handling); password-reset / multi-step procedure → lamina-flow-design (not navigation). Always write the skill id (e.g. lamina-flow-design) in the response. If a sibling skill file is missing, still name the correct id and answer from router knowledge — do not substitute a different skill id.

Step 0 — Init gate when routing to design or verify

Direct mode skips this gate (see above). Only design and verify routes require init.

Before dispatching to design.md or verify.md, run init-required.

If init validates (.lamina/business-context.md exists and passes validation): read it from disk with your file tool, then proceed to the chosen workflow. Do not emit ## Lamina: init required.

Before claiming init is missing: you must attempt to read .lamina/business-context.md with your file tool. Do not emit init-blocked based on assumptions or an empty listing alone — a failed read (ENOENT) is required evidence.

• Problem exploration (“don't know what to build”, early ideation): route to design — frame the user problem, mention design workflow, flows, and edge cases; use design output headings when shaping (### Domain and invariants, etc.) or explicitly dispatch /lamina-design.
• Specific feature: route to design; first reply must literally include the words flows and edge cases (hook graders match those tokens — “Workflows” alone is not enough).
• Verify/audit: route to verify with audit, findings, prioritized improvements.

If init fails, name the intended route in one short sentence (using Router response cues), then emit this contract and STOP. Do not run workflow steps.

Example cue: Intended route: design workflow for <feature or problem> (flows, edge cases) — blocked until init.

Then emit:

## Lamina: init required

### Status
Blocked — `/lamina-init` has not been run on this project, or `.lamina/business-context.md` is incomplete.

### What's missing
- <specific validation failure>

### Next step
Run `/lamina-init` to establish `.lamina/business-context.md`, then retry this command.

### Do not
- Proceed with workflow steps or create `.lamina/` artifacts
- Auto-run init without the user invoking `/lamina-init`
- Treat personas or prior product graphs as a substitute for business context
