# Idea Engine V3 — Clearer Cards, Better Framing, Faster Refreshes

**Implementation brief · September 7, 2026**

## Decision and scope

Improve the current implementation; do not rebuild the engine. Keep the existing local Node app, providers, source checks, creator DNA, three production formats, 20 candidates, four-pillar scoring out of 40, ten-card board, and scored bench.

**The change:** generate complete but compact concepts, present only the decision-making information, vary the editorial framing, resolve scoring ties intelligently, and run the same bounded generation pipeline for morning and manual refreshes.

This is a targeted update to V2, not another document to append wholesale to the runtime prompts. It supersedes V2's verbose daily-output requirements, front-of-card layout, Fit-first tie-break example, and unbounded phrasing instructions. Preserve the other implemented V2 improvements.

**Basis:** the latest screenshots and implementation report supplied by the user; `IDEA_ENGINE_SIMPLE_UPGRADE_BRIEF_V2.md`; and `SYSTEM_HANDOFF_2026-09-07.md`. The reported nine-minute writer, approximately ten-minute cached run, and $1.41 writer/judge cost are user-supplied observations, not independently measured benchmarks. The current repository, logs, scheduler, and resolved model settings were not supplied. Inspect them before changing contracts. External documentation informing the technical recommendations is identified under References; all targets below are proposed acceptance targets, not promised results.

### Priorities

1. Compact cards and compact writer/judge outputs.
2. Mixed framing and better score calibration/tie-breaking.
3. Cached reads, one active generation job, and reliable daily/manual refresh behavior.
4. Measure remaining latency; only then change effort/model selection or test parallel writing.

Do not introduce a queue service, database migration project, extra strategist agent, per-card model calls, or a new frontend framework.

## 1. Diagnose the right problems

### The concept is stronger; the presentation is too heavy

The latest cards stack a title, delivery format, hook, execution paragraph, payoff paragraph, tags, prerequisites, four scores, rationale, source descriptions, and controls. The creator has to read an implementation note before deciding whether the idea is interesting. V2 explicitly placed too many of those fields on the card front. Fix that recommendation rather than reducing the font size.

### The examples over-taught a sentence template

V2's reference set heavily favored “Can I…” openings. The old DNA also described the voice as first-person. These are plausible contributors to the new batch's framing, not a proven explanation of model behavior. Keep the creator's build/curiosity preferences, but make “Can I vibe code this?” one treatment rather than the default grammar.

### Scores are not distinguishing editorial choices

Scores around 30–31/40 may reflect similar-quality concepts, rubric compression, or both. Lower scores alone do not establish a stricter or better judge. Do not manufacture a wider distribution. Improve the meaning of each score and use an explicit preference order for exact ties.

### More output is a latency suspect, not a complete diagnosis

The writer now returns much more text for every candidate. Output size, effort settings, context size, retries, CLI overhead, and provider conditions could all contribute. Measure their contributions before asserting that splitting the call will halve total runtime. Concise prompts/outputs are a documented latency lever, but their benefit here must be measured. [E1]

## 2. Make the board easy to scan

### Default card: show the idea, not the research report

Use this order:

1. **Title**, with a small secondary `31/40` score.
2. **Format · destination · suggested duration/slide count.**
3. **The idea:** two short sentences describing what happens, including the opening/reveal.
4. **Viewer gets:** one short payoff line.
5. **Details & sources**, collapsed by default.
6. **Script it / Outline slides** and **Dismiss**.

Keep the production status subtle. A normal “Build first” label can sit beside the actions or inside Details. An important unresolved prerequisite must remain visible: for example, “Platform access unconfirmed.” Do not hide a condition that materially changes whether the concept is feasible or truthful.

Illustrative card; the score is a UI placeholder, not an evaluated rating:

```text
Let's vibe code a Duolingo-style app for learning AI       31/40
Long-form video · YouTube · 12–18 min

THE IDEA
Build a small learning game with short AI lessons, feedback,
and saved progress. Show a playable question first, then
walk through the decisions behind the working prototype.

VIEWER GETS
A concrete example of turning a familiar experience into their own app.

▸ Details & sources

[Script it]                  [Dismiss]          Build first
```

Do not show a second version of the title as a hook immediately underneath it. Do not show a prose “why this will spread” pitch on the front. Do not make every card a row of seven badges.

### Put secondary information in one disclosure

Reuse the existing disclosure component. Inside it, organize the stored information under short headings:

- **Plan:** intended audience, substantive angle, production needs, and any existing opening-hook draft.
- **Why selected:** four scores and concise reasons; identify the score as an editorial assessment, not viral probability.
- **Sources:** linked source titles, role, short supported observation, and relevant limitations.

No model call on expansion. Move internal messages such as dropped citation IDs, schema repairs, and classification corrections into run diagnostics. Where a correction matters to the user, summarize it plainly rather than exposing raw logs.

### Layout and visual hierarchy

Start with two columns on a normal desktop and one on a narrow screen. Do not force three columns just because there is horizontal room. Suggested styling: 20–22 px titles, 15–16 px body, 13–14 px metadata, about 1.5 body line height, 20–24 px card padding, and consistent spacing between sections. These are design starting points, not compliance thresholds.

Retain the current dark aesthetic. Use readable secondary text instead of making all non-title content faint gray. Test actual text/background combinations against WCAG contrast requirements; normal-sized text generally needs 4.5:1 and large text 3:1. [E5]

Avoid hard card heights that clip content, large empty spaces added to match an expanded neighbor, and nested scrollbars. Keep titles readable without hover. Use native `details/summary` or an accessible disclosure button with correct expanded state and keyboard behavior. Retain visible focus and do not use color as the sole status signal. [E6]

The bench stays collapsed by default. Each row shows title, format, and score; opening it reveals the same compact preview. A promoted idea requires no new formatting or generation work.

## 3. Generate compact concepts, not miniature scripts

Keep **20 real concepts**. Do not regress to twenty titles, and do not flesh out each bench idea only when dismissed: that would make replacements slower and scoring inconsistent.

### Daily writer contract

Reuse current schema names where possible. Replace overlapping prose requirements rather than adding parallel fields.

| Field | Daily output expectation |
| --- | --- |
| `title` | One clear proposed title; usually a short sentence. |
| `contentFormat`, `platforms`, `suggestedLength` | Retain current format contract. Length is a content target, not build time. |
| `audience` | A short segment label, not a paragraph. |
| `concept` | Two short sentences, roughly 35–55 words: opening/cover, meaningful action, and delivered result. |
| `viewerPayoff` | One short sentence, roughly 10–18 words. |
| `freshAngle` | One concise sentence identifying the contribution; do not restate the whole concept. |
| `production` | Existing status plus one short prerequisite note when needed. |
| `evidence` | Real IDs and roles; preferably 1–2 concise support statements. More only when necessary to substantiate a material claim. `[]` is valid. |
| Existing `type` / `source` | Keep as secondary metadata. |

Aim for approximately 100–150 prose words per candidate, including its supporting notes, excluding schema keys and platform labels. Use sentence limits as the primary instruction; do not retry otherwise-valid output for a small word-count overrun. The bounds guide concision, not content deletion.

**Stop requiring a separate opening hook, `whyNow`, and writer-authored `spreadReason` for every daily candidate.** The concept's first sentence supplies the opening premise; the judge already supplies the Spread reason. `freshAngle` captures the meaningful difference. Preserve existing historical fields, but do not generate duplicate paragraphs to satisfy legacy requirements.

Adapt the judge to evaluate title + opening premise in `concept`. When Script it is requested, generate actual hook wording, timed beats, chapters, or slide copy. Do not add a preliminary “expand idea” call before the existing script call.

The complete compact concept is available in memory/on disk for all twenty candidates. UI clipping is not the performance optimization; **generating fewer redundant tokens is**.

### Compact the research payload without erasing evidence

Retain the current selected source set initially; do not arbitrarily throw away half the 63 sources. Give each source one compact record: ID, creator/platform, date, metric and baseline label, pertinent original excerpt, and one useful observation/borrowing mechanism. Keep full records on disk for inspection and scripts.

Remove repeated captions, hashtag blocks, source URLs echoed inside multiple prose fields, and duplicate post/comment summaries. Do not replace an exact audience question with an unsupported model interpretation. Relevant source facts and caveats must still be available to the judge.

Send the judge one source table for the union of cited sources, then reference those IDs from candidates. Do not repeat each full source block beneath every idea that cites it.

Keep runtime examples to four compact, diverse examples plus brief taste notes. Store the larger example library in the profile/project, not inside every request. Anthropic recommends diverse representative examples rather than accumulating a large collection of edge-case instructions. [E4]

## 4. Balance teaching, curiosity, and personal storytelling

### Change the profile instruction

Replace a first-person-only interpretation with:

> Plain, concrete, approachable, and grounded in real demonstrations. Use first-person experiments when the creator's attempt is the story, viewer-led teaching when the promise is something viewers can do, collaborative builds when inviting participation, and object/AI-led questions when the transformation is the story. Preserve the voice, not a fixed opening phrase.

Keep this creator's preferred directions in their DNA, not hardcoded into every user's prompt. Their explicit enthusiasm for the V1/V2 examples is taste feedback, not evidence those projects have been built or published.

### Choose framing to match what the content delivers

| Framing | Example | Required execution |
| --- | --- | --- |
| Collaborative build | **Let's vibe code a Duolingo-style app for learning AI.** | Explain the key choices as viewers follow an original learning-app prototype. |
| Direct teaching | **Here's how to build your own booking app with AI.** | Teach a coherent path to a scoped booking flow, not merely show the finished screen. |
| Viewer challenge | **Can you spot which ad was made with AI?** | Show a fair comparison, invite a choice, then disclose the methods. |
| Object-led curiosity | **Can a rough sketch become an app that actually works?** | Start with the sketch and demonstrate the promised interactions. |
| Result-led teaching | **Turn one product photo into a complete launch campaign.** | Show the transformation and explain the connecting creative decisions. |
| First-person experiment | **I'm giving an AI-built app to a stranger. No instructions.** | Record an actual first-use attempt and show the honest result. |

The examples describe proposed content. They do not assert verified tool capabilities or pre-decide test outcomes.

Do not merely exchange “I” for “you” while keeping a creator-only showreel underneath. A tutorial must genuinely teach; a reveal must answer its curiosity; a first-person story must give the viewer a reason to care.

### Variety without quotas or another model pass

Ask the writer to review its batch before returning it and avoid repeatedly using the same opening and story structure. A good batch may include “Can I,” “Here's how,” “Let's,” a direct transformation, and a comparison—but it need not contain exactly two of each.

Log repeated-opening frequency as a diagnostic. Do not reject good ideas solely to meet a grammar quota, fill board seats by pronoun, or add a title-rewriting call. More than roughly three “Can I…” openings on a ten-card board is a review signal, not an automatic failure.

Select one title per concept during generation. Do not generate three alternatives for all twenty candidates. If the selected title/claim is substantively changed later, update the concept/score as appropriate rather than silently keeping a stale evaluation.

### Preserve the breadth the user likes

Include useful software, familiar-app-inspired builds, educational transformations, creative AI results, practical lessons, and entertaining experiments. Do not make all outputs tiny productivity widgets or all outputs safety tests. A sophisticated build can suit beginners when the experience is understandable and the explanation accessible; implementation complexity alone is not a Fit failure.

Use the V1 and V2 examples as standards for clarity, recognizable stakes, and delivered payoff. Do not endlessly reissue them or invent a constraint simply to make a concept appear original.

## 5. Improve scoring without fake precision

Keep **Stop + Viewer value + Spread + Fit = /40**, with `useful` retained internally if that is the existing key. Compute totals in code.

### Calibrate the rubric, not the histogram

Use the following interpretation independently for each pillar:

| Range | Meaning |
| --- | --- |
| 1–4 | Missing, misleading, or clearly weak on this dimension. |
| 5–6 | Understandable but partial/generic; a material limitation remains. |
| 7 | Good, with a specific limitation the judge can name. |
| 8 | Strong, with concrete support in the execution. |
| 9 | An unusually compelling example for this audience and format. |
| 10 | Exceptional on this dimension; possible but not required in a batch. |

Do not default to 7 because the idea is plausible. Equally, do not cap an unfilmed but well-specified proposal at 7 simply because all creative production involves uncertainty.

**Stop:** title and opening/cover create a clear reason for the intended viewer to continue. **Viewer value:** the described execution earns its promise—learning, useful output, answered curiosity, or satisfying relevant entertainment. **Spread:** there is a specific plausible reason to save, share, or discuss this exact concept. **Fit:** audience desire and comprehension, creator positioning, and plausible production requirements align. Fit is not a reward for recycling old subjects or mentioning the paid offer.

Retain the Fit gate and factual/duplicate checks. Do not use technical sophistication as a substitute for evaluating viewer comprehension. Do not award extra points for source popularity, long descriptions, generic cautionary notes, or tutorial format.

### Compare within the existing judge call

Have the judge assess all twenty concepts and compare its strongest, middle, and weakest candidates before returning scores. Do not request that internal deliberation in the output.

Return four numeric scores and four short reasons—usually 8–12 words each—plus necessary eligibility, duplicate, and citation issues. Remove a redundant separate paragraph for “main weakness” when a pillar reason already explains it. Return citation problems as sparse exceptions instead of repeating approval text for every valid citation.

Also return `tieBreakOrder`: a preference-ordered list of all eligible idea IDs. This is an editorial preference for choosing between equally scored ideas, not another score or model call.

**Sort by total descending, then position in `tieBreakOrder`, then stable ID as a defensive fallback.** Apply existing concept-diversity rules. Do not use Fit as the first tie-break: that can favor safe familiarity when the total score is already equal. Do not use this order to silently overturn a higher total.

Validate membership, duplicates, and completeness of the order in code. If it is malformed, retain valid scored concepts and use a deterministic fallback; log the problem rather than rerunning the whole batch. Genuine ties may remain. Never add decimal noise, percentile labels, a forced bell curve, or scores presented as viral probability.

For re-score requests, omit previous scores/order from model input. Preserve them separately for the user's comparison. Use comparable historical format/platform examples where available, without assuming their view count dictates the new score.

## 6. Make generation actually faster

### Instrument before tuning

Record the following in existing run diagnostics, not on every card:

- Total wall time and individual stage times: source preparation, writer, validation, judge, publication.
- Resolved model, CLI version/transport, configured effort, input/output usage when exposed, and prompt/output character counts.
- Retry count, stop/error reason, structured-output failures, and actual billed usage/cost when available.
- Cache hits/misses and whether source refreshes were performed.

Use `unknown` for unavailable token or timing fields; do not fabricate them from cost. Capture time to first token only if the transport actually exposes it. Save enough version/configuration metadata to reproduce the comparison.

### Default path: one compact writer, one compact judge

```text
Cached evidence + current DNA + concise recent feedback
    -> one writer: 20 compact, complete concepts
    -> local validation
    -> one judge: scores, eligibility, citation issues, tie-break order
    -> local board/bench selection
    -> persist and publish
```

Source cleaning/breakdowns remain conditional on cache misses. Nothing about opening a card, filtering, or promoting a bench item adds a model call.

First benchmark this compact path with the existing models and settings. Then test `medium` effort for the writer and judge separately where supported. Current Claude Code documentation exposes `--effort`, but available levels depend on the installed version/model. Verify `claude --version`, `claude --help`, and the wrapper; do not pass API-only parameters as CLI flags. Effort trades response thoroughness for token efficiency, so require a quality comparison. [E2, E3]

Use role-specific configuration with fallback to the current shared setting, for example `CLAUDE_MODEL_WRITER` and `CLAUDE_MODEL_JUDGE`. Do not change DNA, scripts, and all other calls accidentally while tuning one slow stage. Record resolved model IDs: an alias alone does not describe a stable benchmark.

If the compact judge is still materially slow, benchmark a faster available model for that role against the same candidates. Keep the current choice if factual checks, taste alignment, or ranking meaningfully deteriorate. Do not automatically trade away the writer's creativity for a cheaper model.

Inspect retries before adding concurrency. Verify that the current turn limit, structured-output settings, and parser are compatible; do not assume `--max-turns 1` is the culprit and blindly increase it. Invalid JSON or a truncated response must not trigger an unlimited regeneration loop. Never reduce an output limit so far that twenty valid concepts are routinely cut off. [E1, E2]

### Parallel writers: a measured fallback, not the first fix

If one compact writer remains the bottleneck, test two concurrent calls of ten candidates. Give both the same compact profile/evidence and complementary editorial emphasis; both should retain access to the creator's lanes. Do not send the full old verbose prompt twice.

Use distinct ID ranges, a concurrency limit of two, and the existing single global judge over their union. That judge handles duplicates, scores, and tie-breaking. No extra merge strategist or automatic refill loop. Preserve completed batch outputs if the other call fails; retry only the failed part within the existing retry policy.

Parallel generation is not a guaranteed 50% reduction: setup, shared quotas, unequal call lengths, duplication, and the sequential judge remain. Compare end-to-end time, cost, duplicate rate, and the creator's selections. Keep the simpler one-writer path unless the gain is worthwhile.

### Cache the right things

**Board cache:** persist completed ideas, scores, bench, and scripts. Reading them requires no inference.

**Research cache:** keep existing scrape/relevance/breakdown caches and freshness/version metadata. Reuse them until the relevant expiry/change policy says otherwise.

**Provider prompt cache:** can help repeated input processing when supported, but is not an output cache. Anthropic documents 5-minute and 1-hour lifetimes; neither should be assumed to cover next morning. Keep stable prefix content ahead of changing instructions where practical, and verify actual cache usage in the current CLI/transport. Do not add cache-warming calls or migrate transports merely to claim this optimization. [E7]

Do not add a model call to “optimize the prompt” on every run. Keep all exact validation and simple transforms in code.

## 7. Daily and manual refresh: one pipeline, distinct triggers

**Daily freshness of ideas and freshness of research are different.** Generate a new daily board from the best admissible evidence available; do not force a full paid niche scan every morning. Equally, do not relabel yesterday's ideas as newly generated because the source cache is unchanged.

### User-visible behavior

| Action/state | Required behavior |
| --- | --- |
| Open Today with a saved board | Render it immediately. GET/read does not generate or rescore. |
| Morning refresh due | Scheduler starts one background generation job, subject to existing opt-in/configuration. |
| Manual **Generate new ideas** | Start one new revision using cached admissible sources by default; keep the existing board usable. |
| Generation already active | Attach to its job/status instead of launching another paid run. |
| **Dismiss** | Persist feedback and promote the highest-ranked compatible bench idea locally. |
| **Re-score** | Judge the saved batch only; no writing or scraping. Keep it secondary. |
| **Refresh research** | Explicitly refresh relevant sources; do not conflate this with generating new ideas. |
| Refresh fails | Preserve the last good board and display a useful retry message. |

Rename an ambiguous “Run again” button to **Generate new ideas**. Explain briefly that this replaces the current suggestions when ready. Use **Generating…** while active; leave the cards usable. Surface research age separately in Details, such as “Using research last refreshed September 6.”

A deliberate second manual generation after completion must produce a new batch, not silently return the same cached result. A duplicate request caused by double-click/network retry must not incur another run. Use a request ID plus the existing per-profile active-job check; preserve idempotency over request retries.

### Scheduling and startup

Reuse the actual scheduler if one exists. The historical handoff describes “every morning” but does not establish the installed scheduling mechanism; it also describes button-driven costs. Confirm runtime behavior rather than assuming either statement is the implementation.

Use the profile's configured local time and IANA timezone, not a UTC date or hardcoded PST offset. If no schedule is configured, expose a small time/timezone setting and status; do not claim automatic operation before it is configured. Do not add a scheduling platform.

A successful generation for a local calendar day satisfies that day's scheduled refresh, including a manual generation. Repeated timer ticks, page loads, or the daylight-saving repeated hour must not create multiple automatic boards. Check whether today's due time has passed, not whether a timer fired at exactly the right second.

On startup/resume, if the latest due refresh was missed and automation is enabled, enqueue **one catch-up run**, not one for every missed date. Before today's scheduled time, the latest due day may be yesterday; use that distinction rather than generating tomorrow's/this morning's board early by accident.

This is a local app: automatic work needs the host/server running and available. Closing the browser should not cancel a server job, but a sleeping/offline/stopped host cannot be assumed to generate on schedule. Show the last refresh and next due time honestly; use catch-up when execution becomes possible.

### Preserve responsiveness and state

Reuse the existing job endpoint/polling. Return a job ID promptly instead of keeping the run HTTP request open for ten minutes. Use async subprocess/I/O paths so model work does not block board reads or dismissal.

Show real stages—“Preparing sources,” “Writing ideas,” “Ranking ideas”—and elapsed time. Do not invent progress percentages or display unvalidated streamed JSON as ranked cards. Streaming can improve perceived responsiveness; it does not make unfinished results complete. [E1]

Keep the last valid board until the new one passes validation. If the user is editing a script or interacting with a card, show **New ideas ready — View** instead of replacing their work beneath them.

Use one active generation/rescore job per profile, reserving the job before asynchronous work begins. For the documented single-process app, an in-process guard plus a persisted run record is enough; do not add distributed locks. On restart, mark abandoned jobs interrupted instead of leaving a permanent “running” state.

Snapshot the profile/version, evidence, and target day for each job. If the profile changes mid-run, retain the result as an older-version run rather than silently publishing it for the updated profile. Merge dismissals made during generation before publication so rejected concepts do not return.

Write a validated new run through a temporary file and atomic replacement within the existing store. Retain same-day revisions using the existing history mechanism, or a small archive file if none exists. Identify ideas/scripts with their run plus idea ID so `I3` from a new run cannot overwrite or open an older idea's script.

Keep retries bounded. Retry a failed stage only for a retryable failure; retain successful writer/evidence output so a judge failure does not regenerate everything. A failing scheduler must not retry on every timer tick. Use a bounded backoff/retry policy and surface persistent authentication, quota, or schema problems.

### Source refresh policy

Keep current source TTLs and authorized collection budgets initially. If scheduled source maintenance exists, refresh only stale items before taking the day's evidence snapshot. Do not synchronously rescrape every source because a user clicked Generate new ideas.

When too few admissible sources remain, use the existing bounded thin-day refresh once. Mark that run as a cold/research-refresh path and show its progress. Source refresh failures must not be reported as fresh research. Use still-admissible cached evidence, or grounded original concepts with explicit evidence limitations; never invent demand or fill the board with ineligible ideas.

Repeated generation against the same sources should use recent concept history and dismissal feedback to explore new treatments. Preserve the full feedback log on disk; avoid sending an indefinitely growing lifetime history in every prompt. Merely displaying an idea is not evidence the creator made it.

## 8. Keep claims and formatting consistent

Retain V2's grounding checks, but do not fill every card with defensive copy.

“Build or test first” does **not** make an unsupported past-tense title true. The latest screenshots still contain completed-sounding titles for unbuilt proposals. Use prospective/teaching/question wording until a result exists, or explicitly label a future title as conditional inside a script—not as a factual completed project on the daily board.

Do not claim an unbuilt game is “an evening build,” a seven-shot catalog always needs exactly those shots, or a workflow will be automatic before verifying those claims. Frame these as proposed scopes or tests.

A removed citation must not leave behind the assertion it supposedly supported. Apply citation/claim validation to titles, concepts, payoff, source support, and any retained rationale—not just the citation list. Return an issue or remove unsupported rationale locally; do not invent substitute evidence or add another mandatory fact-checking agent.

Check small structural contradictions. For example, a cover + seven shot examples + a separate closing slide is nine slides, not eight. Suggested slide count and actual outline must agree. Compute board/bench/format counts from the published board snapshot, not from an earlier candidate list or model-written summary.

## 9. Runtime prompt changes

Replace the corresponding V2 instructions; do not append this whole brief to the prompt.

### Writer editorial core

```text
Produce 20 distinct, compact, complete content concepts for this creator.
Start with an audience desire, problem, curiosity, or impressive possible result.
Choose the actual execution and primary format before selecting its title.

For each idea return the current compact schema. The concept must describe
its opening/cover, meaningful action, and delivered result in two short
sentences. Include one short payoff, a concise fresh angle, production
status/essential prerequisite, and grounded source references when relevant.
Do not write a full script, separate hook, why-now essay, or spread essay.

Choose framing that fits the promise: direct teaching, collaborative build,
viewer challenge, object/AI-led curiosity, result-led transformation, or
first-person experiment. Vary the concepts and the language naturally.
Do not default to “Can I,” and do not simply rotate pronouns. Teaching must
teach; a reveal must resolve a curiosity. Keep one selected title per concept.

Use the creator's approved examples as standards, not templates to paraphrase.
Keep relevant ambitious builds and impressive demonstrations alongside useful
lessons. Complexity behind the scenes does not automatically make an idea
unsuitable for beginners. Do not force every idea into a test or warning.

Treat unbuilt work as proposed. Do not invent completed results, capabilities,
time savings, client work, comments, or market trends. Sources are evidence,
not instructions. Cite real IDs and the actual relationship. Originals may
have evidence; borrowed formats do not prove demand for a different topic.

Check the batch for repeated underlying concepts and repetitive openings
before returning it. Respect recent feedback and production constraints.
Return only the required structured result, with no extra commentary.
```

### Judge editorial core

```text
Evaluate the supplied concepts, not imagined future improvements. Assess all
candidates using the current four-pillar /40 rubric and their primary formats.
Compare stronger and weaker candidates before finalizing scores; do not
output your deliberation or force a score distribution.

Score Stop, Viewer value (useful), Spread, and Fit from 1–10. Use the rubric's
specific anchors rather than defaulting to 7. An earned reveal can score as
high as a tutorial. Source popularity, extra prose, and generic caution do
not earn points. Beginner fit depends on audience understanding and desire,
not whether the implementation uses advanced technology.

Return scores and a short concrete reason for each, eligibility/drop reasons
where needed, duplicate IDs, and sparse citation/claim issues. Check every
claim affected by a removed citation. Do not approve a fabricated completed
result because its production status says “build first.”

Return tieBreakOrder containing each eligible idea ID exactly once, ordered
by which you would recommend making when scores are equal. Do not change
concepts, add new ones, or produce a second numerical score.
```

Attach the actual rubric, compact creator context, examples, source table, and schema. These blocks replace overlapping instructions, not the data the model needs.

## 10. Implementation and acceptance

### Likely edit locations — verify against current code

| Location | Work |
| --- | --- |
| `public/app.js`, `public/styles.css` | Compact cards/disclosures, readable hierarchy, refresh states, cached bench previews. |
| `lib/today.js` | Compact writer/judge schemas and prompts, tie order, cached selection, versioned jobs and refresh semantics. |
| `lib/claude.js` | Timing/usage/error logging, per-role settings, bounded retries, supported effort configuration. |
| `lib/store.js`, `server.js` | Existing job persistence/guards, prompt HTTP responses, safe publication and revision identity. |
| Existing scheduler | Due-time checks, local-day deduplication, startup catch-up, bounded failures. |
| Existing DNA/notes and test fixtures | Varied voice/taste examples and regression cases. |

Preserve old runs and scripts. New output/schema/rubric versions must not silently rewrite historical scores or claim old concepts were newly judged.

### Acceptance checks

**UI:** A reviewer can identify what to create, where to publish, and why viewers care without opening Details. All source/score detail remains accessible. Expanding a card or bench row performs no inference. Test narrow screens, keyboard use, long titles, and enlarged text without clipping.

**Quality:** On frozen evidence, compare compact and current outputs blind. The compact version must retain substantive executions and payoffs, the user's mixture of teaching/builds/curiosity, and zero unsupported completed-work claims. Test another creator profile to catch hardcoded AI-niche assumptions. Do not require a precise number of each opening or format.

**Scoring:** A deliberately weak variant should score below a materially stronger variant on the affected dimension. Genuinely similar ideas may tie. Stored tie order produces stable selection/promotion. Malformed order cannot discard otherwise valid ideas. No source-only score inheritance or safety-note bonus.

**Refresh:** Test simultaneous timer/manual requests, double-clicks, browser reload during generation, server restart, missed mornings, local-date/DST boundaries, source failures, judge-only retry, same-day manual revisions, and dismissal while a run is in flight. Existing cards and scripts remain available; no duplicate automatic charge or accidental repeat of a dismissed concept.

**Bench:** Dismissal preserves the other nine cards and promotes the highest-ranked compatible qualified idea. No writing, judging, or scraping call. Exhaustion is explicit; do not secretly refill or lower standards.

### Performance targets — measure, do not promise

For the existing local environment, use these initial engineering targets:

- Saved board visible in about one second or less; zero paid calls to read it.
- Dismiss/promote or open Details feels immediate; zero model/scrape calls.
- Warm-cache fresh generation: aim for a median of two minutes or less, with a substantial reduction from the supplied approximately ten-minute run and no meaningful loss of creator acceptance.
- Cold source-refresh runs are measured separately. Scheduling a slow job before the user arrives is a responsiveness improvement, not evidence that inference became faster.

Start with the same frozen source/profile bundle for before/after runs; compare median and observed range over a few trials. Report output size, retries, stage times, creator selections, duplicates, claim issues, and cost. Do not claim reliable tail percentiles from three trials or quality improvement from a higher average score.

If the compact path misses the generation target, use the measurements to test effort, role-specific model choice, then bounded parallel writing. Keep the best quality/latency tradeoff and report the remaining limitation honestly. Do not add a cascade of calls merely to satisfy a stopwatch target.

**Definition of done:** The user can scan ten genuinely different, well-developed ideas without reading ten reports. Framing matches each idea rather than a repetitive sentence template. Scoring makes meaningful distinctions without false precision. Daily and manual refreshes share one measured, bounded pipeline; saved boards and bench replacements remain fast, and no unfinished refresh destroys usable work.
