lamina-verify

lamina-verify is a skill for Claude Code, Codex from aryaniyaps/lamina. It costs 39 tokens per session (1,173 once invoked), scanned A, original, Apache-2.0.

A verification workflow for a graph-backed product’s user journeys and live interface. It replays defined scenarios through isolated sessions and records evidence about the observed behaviour.

In plain words
What is it for?
Use it after implementation to verify selected workflows, inspect their actors and rules, run persona-based checks, audit the live interface, and publish runtime evidence.
Why use it?
It checks whether an implemented workflow works as intended against the product’s defined rules and user roles. It also records the limits of what could be inspected when a runnable product adapter is unavailable.

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

lamina-verify 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 10d 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 — 91 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/lamina-verify

Verification reads the active GraphVersion and publishes runtime Evidence through isolated Mission sessions. It never discovers, selects, or mutates the active GraphVersion.

Verification Missions are the runtime replay of Persona-bound Experience Cases. They do not replace the earlier design-time Persona simulations that must discover and expand new-feature flows before implementation begins.

Gate and grounding

First read and apply ../lamina/orchestrator/prerequisites/cli-required.md. Stop before all mutations unless the CLI API 1 prerequisite passes.

Require valid .lamina/business-context.md using ../lamina/orchestrator/prerequisites/init-required.md; on failure emit ../lamina/orchestrator/prompts/outputs/init-blocked.md. Then run lamina graph status. Query the requested workflow and its actors, Personas, Operations, invariants, Scenarios, Proofs, Surfaces, dependencies, and Contradictions. Inspect the actual product using a runnable adapter when available; otherwise record static-analysis capability limits. Absence of an Observation is never evidence that behavior is absent.

Read ../lamina/orchestrator/audit-profiles.yaml. Load verify-core.always, then only the verify-core.conditional entries whose when signal appears in the Mission closure or request. For each entry, open the named capability SKILL.md and then its exact reference; do not load sibling topics.

Mission protocol

  1. Run lamina mission compile --workflow <workflow-id>. This must return one independent Mission for every active Persona; there is no maximum of three.
  2. Select adapters only through capability_manifest Resources. Unknown modalities are strings and require no database migration.
  3. Give every Persona an independent adapter context and Run session. Do not share mutable login, browser, process, clock, device, or fixture state.
  4. Exercise every compiled Experience Case, including actor inputs and requiredness, relationship identity/cardinality, duplicates, self-reference, visible states, denial/failure recovery, and invariant probes.
  5. Save large artifacts to the local evidence CAS. Pass normalized events to: lamina mission run <mission-id> --events <events.json>.
  6. mission run returns an isolated staged session. Publish that exact session with lamina session publish <session-id>. When a previously published independent Run advanced the branch, first run lamina session rebase <session-id>, then publish. A staged Run is not verification evidence.
  7. Only adapter-observed events in a published Run become runtime evidence. Persona interpretation remains simulated.
  8. Missing/corrupt evidence, stale source snapshots, budget failures, or capability failures invalidate related readiness; they never silently pass.
  9. Query the resulting GraphVersion and report product gaps, intended-contract gaps, and operational limitations separately. Conflicting Statements remain present as a Contradiction and block approval.

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.

lamina-verify is a skill published in the GitHub repository aryaniyaps/lamina (114 stars, last pushed 5d ago), licensed Apache-2.0. It adds 39 tokens to every session and 1,173 once invoked, about $0.0002 per session on Opus 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 2026-08-30.
