fraimz

name	fraimz
description	create a fraimz, make fraimz, prove it works, frame proof, PR proof, validate experience, e2e evidence, fraimz.html. The full fraimz loop — frame the claim, drive the real app via CDP, validate/repair, output fraimz.html. Use whenever a task ends with "please create a fraimz" or any change needs end-to-end proof.

Skill: fraimz

fraimz is the canonical proof artifact: a single fraimz.html (evals/results/<run-id>/fraimz.html) with one frame per step. Each frame binds a claim, the action the end user took, the assertion that witnesses the side effect, a voiceover that narrates the step, and a validated screenshot. It is the thing a human looks at (and listens to) to understand, at a glance, that an experience works.

This skill owns the prove-it loop. In the demo-driven journey (voiceover skill: script → worktree → build → fraimz → PR) this is how the build is verified; when orchestrating, the orchestrator drives this loop and delegates code repairs to the executor.

Every fraimz is a demo

A fraimz is never a bare test log. The flow declares which demo it is via kind in evals/flows/<id>.flow.mjs:

• kind: "user-facing" — the end user is the protagonist; the frames walk a real journey through the UI. Default for any feature, fix, or UX change.
• kind: "internal" — for changes with no visible surface (perf, storage swaps, invariants, refactors): the frames demonstrate the internal claim in a way a reviewer can still follow. Terminal/tooling demos may set requiresApp: false to run without CDP; their frames carry claims, assertions, and ctx.output command output instead of screenshots (see evals/flows/voiceover-first-dx.flow.mjs).

If you cannot say which of the two your fraimz is, you have not framed the experience yet.

Voiceover first

The narration is the spec and it comes BEFORE the flow (and ideally before the feature) — alignment and approval belong to the voiceover skill / /voiceover. The approved script lives at evals/voiceovers/<flow-id>.md; pnpm fraimz scaffold <flow-id> generates the flow from it, and the runner fails any flow whose narration drifts from the approved file. Every ctx.prove must carry a voiceover (one or two spoken-style sentences about what the viewer sees, never implementation); frames without one are flagged in the artifact — treat that as a failure for any flow you touch.

When this applies

Make fraimz whenever a change can alter behavior observable outside the process: filesystem, runtime DB, server endpoints, sessions, config, provisioning, cloud sync, network. Also for changes you expect to be inert (refactors, renames, dead-code removal): the job is then to prove the canonical core flow is unchanged — open the app → write a message → get a response → close → reopen with the session intact (evals/flows/core-flow.flow.mjs). Pure docs/comments and types-only changes with no runtime path may skip — but say so explicitly.

The loop

Never report success from a click or a return value alone. Every meaningful step is: observe → act → observe → assert — and repair before verdict.

1. Frame the experience as a one-line claim ("user can do X and sees Y") and pick the demo kind. State both back before proceeding.
2. Get the script. Approved voiceover at evals/voiceovers/<id>.md (via the voiceover skill), then pnpm fraimz scaffold <id> — or reuse an existing flow in evals/flows/.
3. Code the flow. The end user is the protagonist (driven via CDP); REST/DB/filesystem checks only witness the side effects. Every meaningful step uses ctx.prove("claim", { voiceover, action, assert, screenshot }).
4. Drive it for real. Launch the app (see below), then pnpm fraimz --flow <id> --cdp-url <electron-cdp-url>.
5. Validate, repair, repeat. If a frame does not support its claim (wrong route, error state, missing text, stale dialog, duplicate image, missing voiceover), fix the visible state or the code and rerun until every claim has a passing assertion, a narrated voiceover, and a valid screenshot.
6. Verdict, on the PR. The run writes fraimz.html + report.md / report.json to evals/results/<run-id>/; post it as a PR comment with pnpm fraimz --flow <id> --pr [number] (--pr alone targets the current branch's PR). Report Passed only when fraimz exists and every claim is backed by an observable assertion; otherwise Incomplete / Failed, stated honestly with repro steps.

Driving the real app

Local Electron (fastest for a worktree you changed):

IPOLLOWORK_ELECTRON_REMOTE_DEBUG_PORT=9826 pnpm dev   # & in background
pnpm fraimz --flow <id> --cdp-url http://127.0.0.1:9826

Daytona sandbox (isolated, VNC-visible; see daytona-electron-test):

bash .devcontainer/test-on-daytona.sh <branch> --artifacts-volume
pnpm fraimz --flow <id> --cdp-url <printed-electron-cdp-url>

The runner default-probes :9825 (Daytona) then :9823 (local pnpm dev); pass --cdp-url for any other port. pnpm evals --all --stack den brings up the cloud stack for env-gated cloud flows.

Pitfalls (learned the hard way)

• Target the right CDP page. A sandbox can expose several targets; ad-hoc browser_eval defaults to the first — pass the iPolloWork target_id when probing manually.
• __ipolloworkControl readiness. Attaches after boot and resets on config reload: ctx.waitFor("Boolean(window.__ipolloworkControl)") before driving, and re-wait after any "Reloading OpenCode config".
• Flows must be idempotent. A failed run can leave dialogs open or state dirty; start steps by restoring the state you need (e.g. Escape a stale dialog).
• Don't race streamed/debounced UI. Wait for the concrete artifact you assert on (the rendered row), not for a spinner to disappear.
• Split reflow from measurement. First a waitFor that returns true only once the DOM actually reflowed, then a separate ctx.eval to measure.
• Screenshot validation takes arrays (requireText: ["foo"], rejectText: [...], hashIncludes: "/route"). A screenshot with no validation metadata is a checkpoint, not proof.
• Assert the regression, not nice-to-haves. Prove what the change guarantees; don't fail the run on a cosmetic extra the fix never promised.
• Eval-only seed affordances are fine behind import.meta.env.DEV on existing eval.* control actions; keep them out of production paths and say so.

ctx.* helpers (the flow API)

ctx.eval, ctx.waitFor, ctx.waitForText, ctx.clickText, ctx.fill, ctx.navigateHash, ctx.control(actionId, args), ctx.expectText, ctx.expectNoText, ctx.expectHashIncludes, ctx.assert, ctx.screenshot(name, { claim, voiceover, requireText, rejectText, hashIncludes }), ctx.output(name, text), and the headline ctx.prove("claim", { voiceover, action, assert, screenshot }). Reference flow: evals/flows/session-search-grouped.flow.mjs.
