name: 3080-brief
description: Create a new source-grounded decision brief in the source format by default (Feishu/Lark, Word/docx, Markdown, or self-contained HTML) with a reader-fit Pyramid opening, one editable or auditable visual covering at least 80% of value-weighted non-appendix claims, and one key-question table. Use when the user names 3080-brief, 3080 brief, 3080skill, 读者视角总结, 3080总结, 3080summary, or 3080-onepager, or asks for a new reader-perspective/cross-functional decision brief with both a 30-second takeaway and one-picture summary. Do not use for editing or polishing the source in place, a generic summary with no 3080/reader/visual requirement, or standalone whiteboard styling. Never modify the source; source-back every number, conclusion, risk, and action.

# 3080 Brief

**30-second judgment, 80% in one picture**

Create a new reader-first brief in the source format by default. Keep the source unchanged.

## Output Contract

Open with `TLDR`, containing exactly three core units:

1. **一句话 / one-sentence judgment**: one highest-level judgment on the first line, followed only when needed by 1–3 short evidence, action, or boundary lines; the whole unit must work within 30 seconds.
2. **一张图 / one-picture summary**: one auditable visual covering at least 80% of value-weighted non-appendix claims; Feishu/Lark uses an editable whiteboard.
3. **一个表 / one key-question table**: 3–5 source-grounded questions with `问题 / 结论 / 为什么` or `Question / Conclusion / Why`.

Title the new artifact `3080 Brief｜原文标题`. Put a compact source link near the top without a standalone source heading.

## Core Contract

When goals conflict, apply: source truth → explicit user requirements → reader comprehension → 30-second judgment → one-picture 80% understanding → visual polish.

- Create a new output. Never edit, overwrite, reorder, comment on, clean up, rename, move, or change permissions on the source.
- Match output type to input type unless explicitly overridden: Feishu/Lark → new Feishu/Lark doc; Word/docx → new `.docx`; Markdown → new Markdown; HTML → new self-contained HTML. Ask only when type/support is materially ambiguous.
- Use the source's primary language unless the user explicitly requests another output language. Conversation, interface, request, or locale language is not an override. Apply the decision to title, TLDR, table, body, and visual.
- Exclude source appendix / 附录 / Appendix content unless the user explicitly includes it.
- Source-back every number, conclusion, risk, and recommendation. Preserve material denominator, period, sample, scope, significance, confidence, and metric definition. Mark unsupported gaps `原文未提供` / `not provided in the source` or `推断` / `inference`.
- Rebuild the narrative around what readers must understand, trust, decide, or do. Do not compress the source mechanically or impose a fixed body order; put decision implication before implementation detail unless implementers are the explicit audience.
- Every rendered brief must carry the mandatory `reading_path` contract in [reading-layout-contract.md](references/reading-layout-contract.md). Lock the body plan before prose; map visible answers, section questions and density. Full body is the default. Shared validation and existing Reader/Source judgments enforce completeness across formats, Fast and scoped delivery, without length quotas.
- For each value-bearing title, heading, and lead, identify the specific object and supported fact, question, change, condition, tradeoff, or impact. Express the reader's key relationship with the fewest necessary words, preserving decisive qualifiers nearby; record it in the existing object-action/result map without inventing an outcome or forcing a contrast.
- Keep prompts, internal process/method language, style names, tool notes, and placeholders out of the artifact. Machine restrictions and semantic colors live in [config/3080-brief.json](config/3080-brief.json).
- Keep generated time, owner, version, location, permissions, and sharing defaults unless requested or operationally required.
- Use `lark-doc` for Feishu docs, `documents:documents` for Word, `lark-whiteboard` for live Feishu preview, and `beautiful-feishu-whiteboard` for Feishu style selection.

## Runtime

Use `standard` by default. Use `fast` only when the user explicitly prioritizes speed or skips independent review; hard source, language, relation, assertion, TLDR, coverage, and visual gates still apply, while audit/replay are skipped and disclosed. Use `strict` when requested or when conclusions affect material resources, policy/rules, causal claims, risk, or broad rollout; it adds exact P0/P1 relation replay and configured reader escalation. Mode details and retry limits are in [review-loop.md](references/review-loop.md).

1. **Route**: determine source/output type, language override, scope, constraints, and artifact lanes. For multiple briefs, follow the efficiency contract. For Feishu, check dependencies before fetch/write; installation or authentication needs separate approval.
2. **Ground**: inspect material non-appendix evidence before prose. Build `source_inventory.md`, untranslated `source_non_appendix.md`, P0/P1 excerpts and `claim_ledger.json`, retaining language, exclusions, sufficiency, identity, evidence ceilings, protected relations, data, risks/actions and omissions. Lock all P0 answers; reopen sources only for gaps/disputes. Initialize a `functional` run per [writing-lifecycle.md](references/writing-lifecycle.md).
3. **Clarify**: before drafting, ask up to three blocking questions only when ambiguity can change the main conclusion, metric meaning/scope, risk boundary, audience, next action, language, or protected relation. For non-blocking gaps, use explicit missing-source/inference labels. Shorten thin-source output instead of making it appear rich.
4. **Draft**: create `brief.json` per [brief.schema.json](references/brief.schema.json); create its mandatory `reading_path`: one reader decision, one question and density per section. Lock `expression_plan` with required answers. Use a source-shaped Pyramid opening and judgment headings. Each unit checkpoint needs text-bound `expression_review`: compare direct alternatives and repeated framing, preserving necessary negatives and TLDR units.
5. **Visualize**: create `visual_spec.json` before drawing and map every block to claim IDs. Choose the smallest content-fit relationship and exactly one allowed theme, with no fixed/silent default. Reach configured weighted coverage without omitting P0 claims. When three or more quantitative claims exist, or the conclusion depends on quantitative evidence, use a real quantitative encoding beyond boxes/prose; show a truthful boundary when extraction is unreliable. Keep semantic colors consistent across visual and body. Image generation is private-safe inspiration only, never the final evidence carrier. For HTML, also create reviewed `html_design.json` and preserve an auditable native-SVG fallback.
6. **Gate and readiness**: create authorized native previews, measure the whole candidate and disposition signals in-run; inspect actual layout. Run checks before review:

```bash
scripts/validate_claim_ledger.py claim_ledger.json
scripts/preflight_check.py DRAFT --source-inventory source_inventory.md --claim-ledger claim_ledger.json
scripts/check_expression_quality.py DRAFT --claim-ledger claim_ledger.json --non-appendix-source source_non_appendix.md
scripts/check_coverage.py claim_ledger.json --visual-spec visual_spec.json
scripts/validate_visual_spec.py visual_spec.json claim_ledger.json
scripts/validate_brief.py brief.json visual_spec.json
```

Validate with `validate_whiteboard.sh` or `validate_html_output.py`. HTML requires the canonical composer, locked contract, build receipt and geometry audit. Fix failures, run the replays below, then validate readiness with the answer receipt; missing/stale evidence blocks audit.

### 7. Stabilize Comprehension Before Audit

Run cropped-picture replay; every P0 must be understood. HTML needs geometry and full-page replay. Primary reads the extracted opening; bind its answer receipt. Resolve blockers before audit. Require `reader_value` v5: direct alternatives and cumulative burden, contextual deletion and source/reader attribution. Disclose Fast self-checks.

### 8. Run The Final Independent Audit

Send the first ready candidate to Reader, Source, and Visualization reviewers concurrently. Register batches and original results in the same run. After changes, use before/after manifests and `plan_review_scope.py`; reuse unaffected PASS results. Stop when scoped verification passes; restart full audit only when required. At three completed batches with current failure, use the labeled draft exit and ask for direction.

### 9. Verify And Deliver

Create authorized Feishu/Word previews before layout checks; checked-deliver afterward. Inspect native XML and the live board. For HTML, use `html_runtime_contract.py` and `build_html_brief.py ... --design-plan html_design.json --contract ... --receipt ...`; validate HTML, receipt, geometry, rich/fallback views and full-page replay. Verify source unchanged, format/language, citation, TLDR, coverage, theme/colors, accessibility, hashes and dependencies.

## Delivery

Before units start [managed execution](references/writing-execution.md) with the host task ID. Map native packets, collect original returns and bind [checked delivery](references/checked-delivery.md) to that run. Fast stays self-checked. Return links and limits; CLI notices last.
