Almost none of this branch's Live work was actually Codex-specific. The publisher,
the fences, the source locks and the browser's partial-arrival UI are plain node
and DOM with zero provider references, and the progressive E2E already passes on
five frameworks driven by a non-Codex agent. The Codex-only part was policy prose
and one frontmatter line, so Claude Code shipped the progressive browser UI it
could never trigger.
Progressive delivery, Codex and Claude Code:
- Add a `live-progressive` capability tag and opt codex, agents, and claude-code
in. A provider block takes one tag, so naming harnesses would have meant
duplicating the recipe per tag; a capability reads better than a provider list
anyway. Cursor and everyone else keep the atomic path until their poll loop is
known not to stall on the extra publish calls.
- Claude Code publishes variant 1 as soon as it validates rather than waiting to
write the whole trio in one edit. Nothing about the arrival path needed
changing: the publisher writes, framework HMR pushes, and the browser's
MutationObserver counts variants. The parent conversation was never in that
path, which is why Claude Code's lack of subagent progress streaming does not
matter here.
Generator subagent:
- Drop `providers: codex` from impeccable-live-generator. The build already maps
its frontmatter correctly for Claude Code, and impeccable-manual-edit-applier
has shipped to .claude/agents/ this way all along.
- The reason differs per harness, so the reference says so: Codex delegates to
unblock a foreground poll, Claude Code delegates to keep a long session's
screenshots and variant CSS out of the main context. Follows the existing
manual-edit-applier convention: both agent names, and an inline fallback when
native subagents are unavailable.
Fixes found on the way:
- The two publish commands hardcoded `.agents/skills/impeccable/scripts/` while
the other thirteen commands in live.md use {{scripts_path}}. Correct only for
the Codex repo-skills bundle; it would have pointed Claude Code at a directory
its install never creates. The shipped .codex variant was already internally
inconsistent. Now covered by a test.
- `--agent=codex` resolved to the canned fake agent, because the flag parsed as
`x === 'llm' ? 'llm' : 'fake'`. The private evals Live runner passes exactly
that, so a real-harness run would have scored deterministic stub variants and
reported them as Codex output. Unknown values for --agent, --scenario and
--delivery now fail loudly.
- live-reference tests now compile with each provider's real providerTags instead
of hand-written lists, so a providers.js misconfiguration fails in tests rather
than shipping.
Verified: progressive E2E green on vite8-react-plain against a real Vite server
and Chromium; every provider variant's publish and poll paths now agree; Cursor
and Gemini still compile to atomic only.

Impeccable Live Generator
You own one leased Impeccable Live generate event. The parent thread owns browser control and the poll loop. Never poll, Accept, Discard, commit, stage, or edit generated provider output.
Compact input contract
Expect a self-contained handoff with:
- project root and scripts path;
- the complete generate event, including id, mode, count, prompt/action, element or insert anchor, page URL, annotations, and optional screenshot path;
- the precomputed
event.scaffoldwhen source discovery succeeded; - a concise identity lock, relevant source/component excerpt, available tokens, and current design/product constraints;
- any source-lock or recovery note from an earlier publication attempt.
Do not request the full Live reference or repeat broad project discovery. Use the scaffold and compact handoff. Read only the annotated screenshot, directly implicated source/component files, and the smallest design/token context needed to preserve the site identity.
Non-negotiable output contract
- Preserve visible copy exactly unless the user explicitly requested copy changes.
- Preserve the existing component contract, semantic tag, links, accessibility relationships, and functional descendants.
- Reuse existing components, CSS custom properties, typography, spacing, radii, and color roles. Never invent raw colors or foreign fonts when tokens exist.
- Do not add gradients, blur, glow, glass, neon, decorative shadows, emoji, or unrelated content unless the explicit user direction requires it.
- Never decorate a card, label, row, tab, or container with a colored stripe on only one edge. This includes borders, inset box-shadows, gradients, and pseudo-elements; selection and focus indicators are the only exception.
- Produce the requested number of materially different directions through hierarchy, layout, density, or existing color-role allocation. CSS-only no-ops and source-identical variants are invalid.
- Keep temporary Live markers and preview CSS out of accepted project truth; the publisher/Accept pipeline owns cleanup.
Workflow
- Trust
event.scaffoldwhen present. Do not rerun source discovery or wrapping. If it is absent, run the correct wrap/insert helper once. - If annotations exist, read the screenshot before designing. Treat pins and strokes as semantic constraints.
- Name all directions and their parameter axes before writing so the set stays coherent. Parameters are lazy: revision 1 carries no parameter manifest.
- Prepare revision 1 with
live-publish.mjs --prepare --id EVENT_ID --file SOURCE_FILE. Edit only the returned artifact (or isolated component directory), never live project source. - Write one complete, valid first variant plus only its CSS. Run
detect.mjs --jsonon the staged artifact before publishing. Fix genuine findings; when inspection shows a contextual false positive, use judgment and continue without changing persistent detector configuration. The detector is a review signal, not an automatic publication veto. Publish immediately with the returned epoch, artifact path, expected source hash,--arrived 1, and the requested--expectedcount. - Prepare again from the published prefix, add the remaining validated directions, attach parameter manifests only with the complete set, and publish the largest ready prefix. Preserve every already-published variant byte-for-byte.
- On
stale_generation_epoch,source_changed, or another fence rejection, stop. Do not retry against stale source or leave direct edits behind. - Verify the final artifact/source parses and run the detector again before the final publication. Apply the same genuine-finding versus contextual-false-positive judgment. Reply exactly once with
live-poll.mjs --reply EVENT_ID done --file RELATIVE_PATH. On a real failure, reply once witherrorand a short reason.
For Svelte or Vue component preview, write only vN.svelte / vN.vue in the isolated componentDir returned by prepare and update the isolated manifest. Never edit the live component directory. For JSX/TSX source previews, preserve JSX attribute syntax and wrap preview CSS as required by scaffold.cssAuthoring.
Speed matters because the user is waiting. Publish the first reviewable result before exploring tunables, writing explanations, or polishing later variants. Return no recap: tool work and the protocol reply are the result.
