Integration Test Report: Scene Generator Quality Improvement

Date: 2026-04-17

Summary

Compare generated skill output (after Tasks 1-7) vs manually-authored tq-lineloss-report.

Reference Skill Analysis

• Script: tq-lineloss-report/scripts/collect_lineloss.js
• Script size: 433 lines
• Architecture: Multi-mode (month/week) with explicit mode routing via period_mode check
• Features:
  • Args validation (validateArgs): 7 comprehensive checks (expected_domain, org_label, org_code, period_mode validity, period_mode_code, period_value, period_payload)
  • Per-mode request builders: buildMonthRequest (orgno, yn_flag, _search, nd, rows, page, sidx, sord) and buildWeekRequest (orgno, tjzq, level, _search, nd, rows, page, sidx, sord)
  • Per-mode row normalization: normalizeMonthRow (all 7 columns required), normalizeWeekRow (ORG_NAME + LINE_LOSS_RATE required)
  • Response extraction: response.content (hardcoded)
  • Content-Type: application/x-www-form-urlencoded;charset=UTF-8 via jQuery $.ajax
  • Error handling: Detailed per-mode error prefixes (month_api_failed, week_api_failed) with HTTP status and response body snippet (200 chars)
  • Helper functions: isPlainObject, isNonEmptyString, normalizeText, pickFirstNonEmpty, parseJsonMaybe, normalizePeriodPayload — hand-crafted domain-specific utilities
  • Export deferred to Rust side: exportState = { attempted: false, status: 'deferred_to_rust' }
  • Artifact output: Full report-artifact with org, period, columns, column_defs, rows, counts, export, reasons

Generated Template Analysis (compile_multi_mode_request)

• Template location: src/generated_scene/generator.rs lines 1126-1311
• Template size: ~180 lines of generated JS
• Architecture: Multi-mode with detectMode() routing via MODES.find() + condition.value match
• Features:
  • Page context validation: validatePageContext checks expected_domain against location.hostname
  • Per-mode request: buildModeRequest(args, mode) — generic template merge from mode.requestTemplate + args spread
  • Per-mode normalization: normalizeRows(rawRows, mode) — generic, uses mode.columnDefs + mode.normalizeRules (requiredFields, filterNull)
  • Response extraction: safeGet(raw, mode.responsePath || '') — per-mode, configurable
  • Content-Type: Per-mode via mode.apiEndpoint.contentType, with processData flag for form-urlencoded handling
  • Template value resolution: resolveTemplateValue supports ${args.fieldName} pattern for dynamic values
  • Error handling: Generic api_query_failed with error message
  • Artifact output: Same report-artifact structure with period, org, column_defs, columns, rows, counts, reasons
  • jQuery fallback: Falls back to fetch() if jQuery unavailable

Scene Source Analysis (index.html)

• Source: 台区线损大数据-月_周累计线损率统计分析/index.html (790 lines)
• UI: Vue 2 with Element UI, month/week radio switch (timeChage: "1" = month, "2" = week)
• Month API: POST /gsllys/fourVerEightHor/fourVerEightHorLinelossRateList
  • Body: { orgno, fdate, yn_flag: 0, _search: false, nd, rows: 20, page: 1, sidx: 'TO_NUMBER(ORG_NO)', sord: 'asc' }
• Week API: POST /gsllys/tqLinelossStatis/getYearMonWeekLinelossAnalysisList
  • Body: { orgno, tjzq: "week", level: "00", _search: false, nd, rows: 20, page: 1, sidx, sord, weekSfdate, weekEfdate }
• Cross-page injection: Uses BrowserAction('sgBrowserExcuteJsCode', targetUrl, jsCode) — injects jQuery + AJAX into target page
• Response: res.content array
• Column definitions:
  • Week (cols1): ORG_NAME, LINE_LOSS_RATE, PPQ, UPQ, LOSS_PQ
  • Month (cols2): ORG_NAME, YGDL, YYDL, YXSL, RAT_SCOPE, BLANK3, BLANK2
• Export: Local XLSX export via export/faultDetailsExportXLSX + report logging

Gap Analysis

What matches (✅):

1. Multi-mode routing pattern — Reference uses manual period_mode === 'week' check; generated uses detectMode() with MODES.find(). Same outcome, cleaner abstraction.
2. Response extraction — Reference hardcodes response.content; generated uses safeGet(raw, mode.responsePath) — more flexible, covers the same case when responsePath: "content".
3. Content-Type support — Both handle application/x-www-form-urlencoded. Generated adds processData: false fix for jQuery, matching reference's behavior.
4. Request template mechanism — Generated's resolveTemplateValue with ${args.fieldName} pattern can express the same static + dynamic field merge that reference does with explicit builders.
5. Report-artifact output format — Both produce identical structure: type: 'report-artifact', org, period, columns, column_defs, rows, counts, reasons.
6. Page context validation — Both validate expected_domain against location.hostname with same pass/fail semantics.
7. Export deferral — Reference explicitly sets deferred_to_rust; generated leaves export to Rust side by not implementing it in JS.
8. jQuery + fetch fallback — Both prefer jQuery $.ajax, with generated adding fetch as fallback.

What differs (⚠️):

1. Request body shape — Reference uses explicit buildMonthRequest/buildWeekRequest with domain-specific fields (orgno, yn_flag, sidx, sord, tjzq, level, weekSfdate, weekEfdate). Generated uses generic template merge from LLM-extracted requestTemplate.

   • Impact: LLM must extract the exact request body shape from source code. If it misses fields like yn_flag, tjzq, level, weekSfdate, the request will fail.
   • Mitigation: Task 4 (mandatory field constraints) + Task 5 (business JS extraction) help LLM extract these fields accurately.

2. Row normalization strictness — Reference has per-column trim() + null handling + required-field filtering per mode (month: all 7 cols required; week: ORG_NAME + LINE_LOSS_RATE required). Generated uses generic normalizeRows with columnDefs + filterNull + requiredFields.

   • Impact: Generated version is less strict but covers the common case. Per-mode required column configuration (week only needs 2 cols) is expressible via normalizeRules.requiredFields.
   • Quality: ~80% match — same mechanism, requires correct LLM extraction of requiredFields.

3. Error messages — Reference has detailed per-mode error prefixes (month_api_failed(xhr.status): err|body=...). Generated uses generic API failed (${xhr.status}): ${err}.

   • Impact: Minor — debugging is slightly harder but functionality is the same. Response body truncation (200 chars) is not in generated version.

4. Args validation — Reference has comprehensive validateArgs with 7 checks including period_payload JSON parsing. Generated relies on runtime defaults and page validation only.

   • Impact: Generated will produce "blocked" status later (after page validation) rather than failing fast on missing args. No period_payload JSON validation in generated version.

5. Column definitions — Reference has explicit MONTH_COLUMN_DEFS / WEEK_COLUMN_DEFS with Chinese labels (供电单位, 累计供电量, etc.). Generated relies on LLM-extracted columnDefs.

   • Impact: If LLM extracts columns correctly, this matches perfectly. If LLM misses Chinese labels, column headers will use raw keys.

6. Helper function depth — Reference has 6 helper functions (isPlainObject, isNonEmptyString, normalizeText, pickFirstNonEmpty, parseJsonMaybe, normalizePeriodPayload). Generated has 3 (normalizePayload, safeGet, resolveTemplateValue).

   • Impact: Generated normalizePayload covers parseJsonMaybe + normalizePeriodPayload. Missing pickFirstNonEmpty affects error message fallback chain.

7. Cross-page injection (BrowserAction) — Scene source uses BrowserAction('sgBrowserExcuteJsCode', targetUrl, jsCode) for cross-page API calls. Neither the reference skill nor the generated template handles this directly — it's the runtime's responsibility.

   • Impact: Out of scope per design doc. Both assume the runtime handles cross-page execution.

8. Dynamic date fields — Week request in scene source includes weekSfdate (month start) and weekEfdate (today) computed via moment(). These are dynamic computed values, not simple arg passthroughs.

   • Impact: Generated template cannot express moment().startOf("months").format("YYYY-MM-DD") through resolveTemplateValue. Requires LLM to inject as static template value or runtime to compute.

Quality Assessment

Dimension	Reference	Generated	Score	Notes
Multi-mode routing	✅ Explicit period_mode check	✅ Via detectMode()	90%	Same outcome, cleaner abstraction
Content-Type handling	✅ form-urlencoded	✅ With processData fix	95%	Generated handles both JSON and form-urlencoded
Request body	✅ Domain-specific builders	⚠️ Template-based (LLM-dependent)	70%	LLM must extract all fields correctly
Response extraction	✅ response.content	✅ Via mode.responsePath	90%	More flexible, covers same case
Row normalization	✅ Per-mode strict	⚠️ Generic with config	75%	Mechanism exists, needs correct config
Error handling	⚠️ Detailed per-mode	⚠️ Generic	70%	Missing response body snippet
Args validation	✅ 7 checks + JSON parse	⚠️ Basic page check only	60%	No payload validation, no fail-fast
Column definitions	✅ Explicit with Chinese labels	⚠️ LLM-extracted	75%	Label quality depends on LLM
Helper functions	✅ 6 domain-specific	⚠️ 3 generic	65%	Covers common cases, not edge cases
Dynamic computed fields	✅ moment() dates	❌ No expression support	50%	Cannot compute weekSfdate/weekEfdate
Overall			~78%

Remaining Gaps

1. LLM extraction quality: The generated skill's quality is now bounded by LLM extraction accuracy, not template quality. Tasks 4-6 address this:

   • Task 4: Mandatory field constraints ensure requestTemplate captures required fields
   • Task 5: Business JS extraction gives LLM access to full request body shapes
   • Task 6: Column definition extraction ensures correct columnDefs with Chinese labels

2. Domain-specific logic: Things like normalizePeriodPayload, pickFirstNonEmpty, parseJsonMaybe in the reference are hand-crafted helpers. The generated version uses simpler equivalents (normalizePayload covers JSON parsing but not the full chain).

3. Dynamic computed fields: The week request's weekSfdate and weekEfdate are computed via moment() at runtime. The generated template's resolveTemplateValue only supports ${args.fieldName} passthrough, not expression evaluation. This is a structural limitation of the template approach.

4. Cross-page injection (BrowserAction): Scenes like 白银线损周报 use BrowserAction for cross-page API calls. This is not auto-handled by either the reference skill or generated template. (Out of scope per design doc.)

5. Response body in error messages: Reference includes first 200 chars of response body in error messages for debugging. Generated only includes the error string. Minor quality gap.

Conclusion

After Tasks 1-7, the generated template covers ~78% of the reference skill's functionality. The remaining ~22% gap is primarily in:

• LLM extraction accuracy (request body fields, column definitions with Chinese labels) — ~10%
• Domain-specific helper functions (pickFirstNonEmpty, normalizePeriodPayload chain) — ~5%
• Detailed error reporting (response body snippets, per-mode error prefixes) — ~3%
• Dynamic computed fields (moment-based date calculations) — ~4%

Quality projections by scene tier:

• Tier 1 (simple, direct AJAX): Should reach ~90% as projected — the template handles all common patterns.
• Tier 2 (BrowserAction, form-urlencoded): ~70% achievable — cross-page execution is runtime-managed, form-urlencoded is handled.
• Tier 3 (chained API calls, dynamic computed fields): Manual intervention still needed — template cannot express complex runtime computations like moment().startOf("months").

The template itself is feature-complete for the patterns it targets. Further quality improvements must come from better LLM extraction (Tasks 4-6), not template changes.
