+``` + +The wrap script already gives you a single-rooted JSX wrapper: a `
` outer element with the marker comments tucked inside. Drop the variants block above into the "Variants: insert below this line" comment and the source stays valid TSX. + +### 7. Parameters (composition-sized, 0–4 per variant) + +Each variant can expose **coarse** knobs alongside the full HTML/CSS replacement. The browser docks a small panel to the right of the outline with one control per parameter. The user drags/clicks and sees instant feedback: there is zero regeneration cost because the knob toggles a CSS variable or data attribute that the variant's scoped CSS is already authored against. + +**What “optional” does not mean.** Parameters are not nice-to-have decoration on large work. The word meant “omit controls that are redundant or cosmetic,” not “default to zero because three variants were enough work.” + +**When to add.** As soon as the variant’s scoped CSS has a meaningful continuous or stepped axis: density, color amount, type scale, motion intensity, column weight, and so on. If you can imagine the user muttering “a bit tighter” or “a touch more accent” **without** wanting a full regeneration, wire that axis. **Not** micro-margins or one-off nudges; those are not parameters. + +**Freeform (`action` is `impeccable`) bias.** You did not load a sub-command reference, so you must **choose** signature axes yourself. Match the budget table: for a hero or large composition, that means **2–3 axes per variant**, not 1. Prefer knobs that sit on the dimensions where your three variants actually differ (if density varies, expose it as a `steps` knob; if color commitment varies, expose it as a `range`). A hero that ships with **0** params is almost always a mistake, not a judgment call. A hero with exactly **1** param is underweight unless the design is genuinely a fixed-point comparison. Start from the budget table, not from zero. + +**Budget scales with the element's visual weight, not token budget.** Knobs need real estate to read as tunable; three sliders on a single control are noise. + +- **Leaf / tiny**: a single button, icon, input, bare heading, solitary paragraph: **0 params.** +- **Small composition**: labeled input, simple card, short callout (≤ ~5 visual children): **0–1** params when one dominant axis is obvious; otherwise **0.** +- **Medium composition**: section component, nav cluster, dense card, short feature block (6–15 visual children): **target 2**; **1** is acceptable if the block is simple; **0** only when variants are truly fixed points. +- **Large composition**: hero section, full page region, spread layout, strong internal structure (16+ visual children or multiple sub-sections): **target 2–3**; **up to 4** when several independent axes (e.g. structure `steps` + `density` + one accent) are all authored in scoped CSS. + +**When in doubt, ask whether a dial exists before defaulting to zero.** The user can always request more variants, but the point of live mode is instant tuning without another Go. Crowding the panel is bad; **under-shipping** knobs on a dense composition is the more common failure for freeform. Count by **visual** children, not DOM depth; a shallow-but-wide hero is still large. + +**Hard cap per variant**: at most **four** parameters so the panel stays legible; rare fifth only if the reference explicitly allows it. + +**How to declare.** Put a JSON manifest on the variant wrapper (HTML/JSX path). **On the Svelte `svelte-component` path, do not use this attribute** (Svelte can't compile `{` inside an attribute value). Declare params in `componentDir/params.json` keyed by variant number instead (see the Svelte component paragraph in the wrap section). The param schema below is identical for both paths. + +```html +
+ ...variant content... +
+``` + +**Three kinds:** + +- `range`: smooth slider. Drives a CSS custom property `--p-` on the variant wrapper. Author CSS with `var(--p-color-amount, 0.5)`. Fields: `min`, `max`, `step`, `default` (number), `label`. +- `steps`: segmented radio. Drives a data attribute `data-p-` on the variant wrapper. Author CSS with `:scope[data-p-density="airy"] .grid { ... }`. Fields: `options` (array of `{value, label}`), `default` (string), `label`. +- `toggle`: on/off switch. Drives BOTH a CSS var (`--p-: 0|1`) and a data attribute (present when on, absent when off). Use whichever is more convenient. Fields: `default` (boolean), `label`. + +**Signature params per action.** For named sub-commands, read that action’s `reference/.md` for one or two **MUST** params (e.g. `layout` → `density`). Those are non-negotiable when the design can express them. **Freeform has no file-level MUST**; the **Freeform (`impeccable`) bias** in this section is the stand-in. If the user’s action is both stylized and sub-command (e.g. `colorize`), the sub-command’s MUST list takes precedence for its axes; still respect the **Hard cap** and add no redundant duplicate knobs. + +**Reset on variant switch.** User dials density on v1, flips to v2, v2 starts at v2's declared defaults. Known limitation; preservation across variants may land later. + +**On accept**, the browser sends the user's current values in the accept event. `live-accept.mjs` writes them as a sibling comment: + +```html + +``` + +The carbonize cleanup step (see below) reads that comment and bakes the chosen values into the final CSS. For `steps`/`toggle` attribute selectors: keep only the branch matching the chosen value, drop the others, collapse `:scope[data-p-density="packed"] .grid` to a semantic class rule. For `range` vars: either substitute the literal or keep the var with the chosen value as its new default. + +### 8. Signal done + +```bash +node .github/skills/impeccable/scripts/live-poll.mjs --reply EVENT_ID done --file RELATIVE_PATH +``` + +`RELATIVE_PATH` is relative to project root (`public/index.html`, `src/App.tsx`, etc.); the browser fetches source directly if the dev server lacks HMR. + +Then run `live-poll.mjs` again immediately. + +### Aborting an in-flight session + +If wrap or generation fails after the browser has flipped to GENERATING (e.g. wrap landed on the wrong source branch and you've already reverted it, or generation hit an unrecoverable error), tell the **browser** so its bar resets to PICKING: + +```bash +node .github/skills/impeccable/scripts/live-poll.mjs --reply EVENT_ID error "Short reason" +``` + +Don't run `live-accept --discard` for this; that's a pure file mutator, the browser doesn't see it, and the bar gets stuck on the GENERATING dots forever (the user has to refresh). `--discard` is only correct when the **browser** initiated the discard (user clicked ✕ during CYCLING) and the agent is just running source-side cleanup the browser already triggered. + +## Handle fallback + +When wrap returns `fallback: "agent-driven"`, the deterministic flow doesn't apply. Pick up here. + +The goal is the same: give the user three variants to choose from AND persist the accepted one in a place the next build won't wipe. The difference is that you have to pick the right source file yourself. + +### Step 1: Identify where the element actually lives + +Use the error payload: + +- `element_not_in_source` with `generatedMatch: "public/docs/foo.html"`: the served HTML is generated. Find the generator (grep for writers of that path, e.g. `scripts/build-sub-pages.js`, an Astro/Next template) and locate the template or partial that emits this element. +- `element_not_found`: the element is runtime-injected. Look for the component that renders it (React/Vue/Svelte), the JS that assembles it, or the data source that feeds it. +- `file_is_generated` with `file: "..."`: user pointed at a generated file explicitly. Same resolution as `element_not_in_source`. + +Read the candidate source until you're confident where a change to the element would belong. If the change is purely visual, that source might be a shared stylesheet, not the template. + +### Step 2: Show three variants in the DOM for preview + +The browser bar is waiting for variants. Even without a wrapper in source, you still need to show something: + +1. Manually write the wrapper scaffold into the **served** file (the one the browser actually loaded).

…
`. +2. Insert your three variant divs inside it, same shape as the deterministic path. +3. Signal done with `--reply EVENT_ID done --file `. The browser's no-HMR fallback will fetch and inject. + +This served-file edit is **temporary**: next regen wipes it, and that's fine. The real work happens on accept. + +### Step 3: On accept, write to true source + +When the accept event arrives (`_acceptResult.handled` will usually be `false` here because accept also refuses to persist into generated files; see Handle accept for the carbonize branch), extract the accepted variant's content and write it into the source you identified in Step 1: + +- Structural change → edit the template / component source. +- Visual-only change → add or update rules in the appropriate stylesheet; remove the inline `' : '')); + if (paramValues && Object.keys(paramValues).length > 0) { + lines.push( + bodyIndent + commentSyntax.open + ' impeccable-param-values ' + id + ': ' + JSON.stringify(paramValues) + ' ' + commentSyntax.close, + ); + } + lines.push(bodyIndent + commentSyntax.open + ' impeccable-carbonize-end ' + id + ' ' + commentSyntax.close); + lines.push(bodyIndent + '

+``` + +The wrap script already gives you a single-rooted JSX wrapper: a `
` outer element with the marker comments tucked inside. Drop the variants block above into the "Variants: insert below this line" comment and the source stays valid TSX. + +### 7. Parameters (composition-sized, 0–4 per variant) + +Each variant can expose **coarse** knobs alongside the full HTML/CSS replacement. The browser docks a small panel to the right of the outline with one control per parameter. The user drags/clicks and sees instant feedback: there is zero regeneration cost because the knob toggles a CSS variable or data attribute that the variant's scoped CSS is already authored against. + +**What “optional” does not mean.** Parameters are not nice-to-have decoration on large work. The word meant “omit controls that are redundant or cosmetic,” not “default to zero because three variants were enough work.” + +**When to add.** As soon as the variant’s scoped CSS has a meaningful continuous or stepped axis: density, color amount, type scale, motion intensity, column weight, and so on. If you can imagine the user muttering “a bit tighter” or “a touch more accent” **without** wanting a full regeneration, wire that axis. **Not** micro-margins or one-off nudges; those are not parameters. + +**Freeform (`action` is `impeccable`) bias.** You did not load a sub-command reference, so you must **choose** signature axes yourself. Match the budget table: for a hero or large composition, that means **2–3 axes per variant**, not 1. Prefer knobs that sit on the dimensions where your three variants actually differ (if density varies, expose it as a `steps` knob; if color commitment varies, expose it as a `range`). A hero that ships with **0** params is almost always a mistake, not a judgment call. A hero with exactly **1** param is underweight unless the design is genuinely a fixed-point comparison. Start from the budget table, not from zero. + +**Budget scales with the element's visual weight, not token budget.** Knobs need real estate to read as tunable; three sliders on a single control are noise. + +- **Leaf / tiny**: a single button, icon, input, bare heading, solitary paragraph: **0 params.** +- **Small composition**: labeled input, simple card, short callout (≤ ~5 visual children): **0–1** params when one dominant axis is obvious; otherwise **0.** +- **Medium composition**: section component, nav cluster, dense card, short feature block (6–15 visual children): **target 2**; **1** is acceptable if the block is simple; **0** only when variants are truly fixed points. +- **Large composition**: hero section, full page region, spread layout, strong internal structure (16+ visual children or multiple sub-sections): **target 2–3**; **up to 4** when several independent axes (e.g. structure `steps` + `density` + one accent) are all authored in scoped CSS. + +**When in doubt, ask whether a dial exists before defaulting to zero.** The user can always request more variants, but the point of live mode is instant tuning without another Go. Crowding the panel is bad; **under-shipping** knobs on a dense composition is the more common failure for freeform. Count by **visual** children, not DOM depth; a shallow-but-wide hero is still large. + +**Hard cap per variant**: at most **four** parameters so the panel stays legible; rare fifth only if the reference explicitly allows it. + +**How to declare.** Put a JSON manifest on the variant wrapper (HTML/JSX path). **On the Svelte `svelte-component` path, do not use this attribute** (Svelte can't compile `{` inside an attribute value). Declare params in `componentDir/params.json` keyed by variant number instead (see the Svelte component paragraph in the wrap section). The param schema below is identical for both paths. + +```html +
+ ...variant content... +
+``` + +**Three kinds:** + +- `range`: smooth slider. Drives a CSS custom property `--p-` on the variant wrapper. Author CSS with `var(--p-color-amount, 0.5)`. Fields: `min`, `max`, `step`, `default` (number), `label`. +- `steps`: segmented radio. Drives a data attribute `data-p-` on the variant wrapper. Author CSS with `:scope[data-p-density="airy"] .grid { ... }`. Fields: `options` (array of `{value, label}`), `default` (string), `label`. +- `toggle`: on/off switch. Drives BOTH a CSS var (`--p-: 0|1`) and a data attribute (present when on, absent when off). Use whichever is more convenient. Fields: `default` (boolean), `label`. + +**Signature params per action.** For named sub-commands, read that action’s `reference/.md` for one or two **MUST** params (e.g. `layout` → `density`). Those are non-negotiable when the design can express them. **Freeform has no file-level MUST**; the **Freeform (`impeccable`) bias** in this section is the stand-in. If the user’s action is both stylized and sub-command (e.g. `colorize`), the sub-command’s MUST list takes precedence for its axes; still respect the **Hard cap** and add no redundant duplicate knobs. + +**Reset on variant switch.** User dials density on v1, flips to v2, v2 starts at v2's declared defaults. Known limitation; preservation across variants may land later. + +**On accept**, the browser sends the user's current values in the accept event. `live-accept.mjs` writes them as a sibling comment: + +```html + +``` + +The carbonize cleanup step (see below) reads that comment and bakes the chosen values into the final CSS. For `steps`/`toggle` attribute selectors: keep only the branch matching the chosen value, drop the others, collapse `:scope[data-p-density="packed"] .grid` to a semantic class rule. For `range` vars: either substitute the literal or keep the var with the chosen value as its new default. + +### 8. Signal done + +```bash +node .opencode/skills/impeccable/scripts/live-poll.mjs --reply EVENT_ID done --file RELATIVE_PATH +``` + +`RELATIVE_PATH` is relative to project root (`public/index.html`, `src/App.tsx`, etc.); the browser fetches source directly if the dev server lacks HMR. + +Then run `live-poll.mjs` again immediately. + +### Aborting an in-flight session + +If wrap or generation fails after the browser has flipped to GENERATING (e.g. wrap landed on the wrong source branch and you've already reverted it, or generation hit an unrecoverable error), tell the **browser** so its bar resets to PICKING: + +```bash +node .opencode/skills/impeccable/scripts/live-poll.mjs --reply EVENT_ID error "Short reason" +``` + +Don't run `live-accept --discard` for this; that's a pure file mutator, the browser doesn't see it, and the bar gets stuck on the GENERATING dots forever (the user has to refresh). `--discard` is only correct when the **browser** initiated the discard (user clicked ✕ during CYCLING) and the agent is just running source-side cleanup the browser already triggered. + +## Handle fallback + +When wrap returns `fallback: "agent-driven"`, the deterministic flow doesn't apply. Pick up here. + +The goal is the same: give the user three variants to choose from AND persist the accepted one in a place the next build won't wipe. The difference is that you have to pick the right source file yourself. + +### Step 1: Identify where the element actually lives + +Use the error payload: + +- `element_not_in_source` with `generatedMatch: "public/docs/foo.html"`: the served HTML is generated. Find the generator (grep for writers of that path, e.g. `scripts/build-sub-pages.js`, an Astro/Next template) and locate the template or partial that emits this element. +- `element_not_found`: the element is runtime-injected. Look for the component that renders it (React/Vue/Svelte), the JS that assembles it, or the data source that feeds it. +- `file_is_generated` with `file: "..."`: user pointed at a generated file explicitly. Same resolution as `element_not_in_source`. + +Read the candidate source until you're confident where a change to the element would belong. If the change is purely visual, that source might be a shared stylesheet, not the template. + +### Step 2: Show three variants in the DOM for preview + +The browser bar is waiting for variants. Even without a wrapper in source, you still need to show something: + +1. Manually write the wrapper scaffold into the **served** file (the one the browser actually loaded). Use the same structure `live-wrap.mjs` produces; `
…
`. +2. Insert your three variant divs inside it, same shape as the deterministic path. +3. Signal done with `--reply EVENT_ID done --file `. The browser's no-HMR fallback will fetch and inject. + +This served-file edit is **temporary**: next regen wipes it, and that's fine. The real work happens on accept. + +### Step 3: On accept, write to true source + +When the accept event arrives (`_acceptResult.handled` will usually be `false` here because accept also refuses to persist into generated files; see Handle accept for the carbonize branch), extract the accepted variant's content and write it into the source you identified in Step 1: + +- Structural change → edit the template / component source. +- Visual-only change → add or update rules in the appropriate stylesheet; remove the inline `' : '')); + if (paramValues && Object.keys(paramValues).length > 0) { + lines.push( + bodyIndent + commentSyntax.open + ' impeccable-param-values ' + id + ': ' + JSON.stringify(paramValues) + ' ' + commentSyntax.close, + ); + } + lines.push(bodyIndent + commentSyntax.open + ' impeccable-carbonize-end ' + id + ' ' + commentSyntax.close); + lines.push(bodyIndent + '
