What it does

Lamina Evaluation is an agent skill from aryaniyaps/lamina. Judge product usability and evidence quality. Use when running Persona-based walkthroughs on a built product, planning an expert heuristic review, defining evidence-backed success metrics, or checking quantitative claims without inventing measurements. Use lamina-research to plan or synthesize evidence collection and lamina-ux to design interaction behavior.

Its SKILL.md is about 430 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `references/heuristic-review.md`, `references/quantitative-validation.md` and `references/usability-evaluation.md`).

It sits in Frontend & Design, covering UX design, Product metrics and Digital forensics. The repository describes itself as: Headless product design for AI coding agents, backed by a transactional product graph | Design how it works, verify what you ship. The licence is Apache-2.0.

When your agent uses it

  • Running Persona-based walkthroughs on a built product

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. Match the request's primary evaluation method to one row below.

What it can do on your machine

Read from SKILL.md and the folder at commit af269ef. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Lamina Evaluation loads about 432 tokens when it runs, and up to ~1k if it reads all its reference files. Until then it costs about 95 tokens; SKILL.md has 161 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~95
When it runs · the whole SKILL.md, loaded when a task matches
~432
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Lamina Evaluation

Reference-loading protocol

  1. Match the request's primary evaluation method to one row below.
  2. Open that linked reference before answering. Add another only when a second method materially changes the answer; do not preload the directory.
  3. Start the response with Using lamina-evaluation: <topic path(s)> so the selected evaluation lens is auditable.

Topic index

Evaluation signalReadAdds
Need actors to attempt workflows and edge probes on a built productActor EvaluationPersona-based walkthrough method and reproducible blockers
Need specialists to inspect a contract or live product through explicit lensesExpert Lens Reviewparallel lens coverage tied to evidence and contract refs
Need success metrics, analytics interpretation, or experiment claimsMetrics Disciplinemeasurement boundaries and anti-fabrication rules

Working rule

Use the smallest sufficient reference set. Actor evaluation requires a runnable product; use expert review before build or when a lens-specific inspection is requested. Pair either with metrics discipline only when real measurements or a measurement plan are in scope.
