+## Duplicate (D) — same instruction stated ≥2 times
+
+**D-01** Lines 312–329 vs 333–346  
+Refinement "Permitted actions" / "Prohibited actions" and the compact "For class diagrams / For sequence diagrams" bullets cover exactly the same refinement policy. Same content stated twice in adjacent blocks.
+
+**D-02** Lines 310, 389, 405  
+"Start with skeleton (reduces generation time)" / "Retrieve skeleton from working memory" stated 3× across Step 3.4 sub-sections (compact refinement block, class diagram key-points, sequence diagram key-points).
+
+**D-03** Lines 333–337 vs 349–366  
+Compact "For class diagrams" workflow (5 bullets) and expanded "Dependency diagram Step 1/Step 2" block describe identical class diagram refinement actions. Fully redundant.
+
+**D-04** Lines 340–346 vs 404–414  
+Compact "For sequence diagrams" workflow and expanded "Flow description Step 1/Step 2" describe identical sequence diagram refinement actions. Fully redundant.
+
+**D-05** Lines 535–551 vs 215–226  
+Step 3.5 lists all 9 pre-filled placeholders in a "Already pre-filled (keep as-is)" block; Step 3.2 already enumerates the same 9 with descriptions. The Step 3.5 list adds nothing.
+
+**D-06** Lines 367–378 vs 480–485  
+Class diagram example (LoginAction/LoginForm/UniversalDao) appears in "Dependency diagram" sub-section and again in "Output format examples / Component Summary Table" area. Same mermaid block shown twice.
+
+**D-07** Lines 396–401 vs 478–484  
+Component Summary Table format shown with example in Step 3.4 main area (lines 396–401) and repeated in "Output format examples" block (lines 478–484). Identical content.
+
+**D-08** Lines 469–474 vs 486–493  
+"Nablarch usage" bullet list (Class name, Code example, Important points, etc.) and "Important Points prefixes" block both enumerate the ✅⚠️💡🎯⚡ prefixes. Stated twice in the same section.
+
+**D-09** Lines 320, 343, 411  
+"Add error handling branches using `alt`/`else` blocks" instruction appears in Permitted actions, compact sequence workflow, and expanded sequence workflow.
+
+**D-10** Lines 321, 344, 412  
+"Add loops for repetitive operations using `loop` blocks" appears in Permitted actions, compact sequence workflow, and expanded sequence workflow.
+
+**D-11** Lines 322, 345, 413  
+"Add explanatory notes using `Note over` syntax" appears in Permitted actions, compact sequence workflow, and expanded sequence workflow.
+
+**D-12** Lines 455–462 vs 312–329  
+"Key points" block for sequence diagrams re-lists skeleton retrieval + method name guidance that already appears in the expanded refinement block above it.
+
+**D-13** Lines 380–394 vs 355–366  
+"Key points" block for class diagram re-lists `classDiagram` syntax, `<<Nablarch>>` marking, and class limit — all already covered in the Step 2 refinement block above.
+
+**D-14** Lines 633–640 vs 160–178 (Step 3.1)  
+"Best practices / Template compliance" section restates: read template first, no section numbers, no extra sections, verify compliance. All are already stated in-step (Step 3.1 and Step 3.5 verify list).
+
+**D-15** Lines 641–644 vs 103–106 (Step 1.6)  
+"Best practices / Scope management" restates stop-at-framework-boundaries and ask-user-before-expanding, already stated in Step 1.
+
+**D-16** Lines 645–649 vs 103–106 (Step 1.5–1.6)  
+"Best practices / Dependency tracing" restates stop at framework boundaries and Entity classes, already in Step 1.
+
+**D-17** Lines 650–654 vs 143–153 (Step 2.3)  
+"Best practices / Knowledge integration" restates knowledge-files-only and cite-sources rules, already in Step 2.
+
+**D-18** Lines 229–233 vs 235–242  
+Step 3.2 "Error handling" block and "Validation" block both address the case where the script fails / produces wrong output. Partial overlap of error scenarios.
+
+---
+
+## Conflict (C) — two instructions contradict each other
+
+**C-01** Lines 357–362 vs 370 (example)  
+Rules say avoid generic labels "uses", "calls", "has". The example at line 370 uses `LoginAction ..> UniversalDao : uses`. Rule and example contradict.
+
+**C-02** Lines 333–337 vs 349–366  
+Compact "For class diagrams" bullets and expanded "Dependency diagram Step 1/Step 2" are both presented as the authoritative class diagram refinement procedure. Reader cannot know which governs.
+
+**C-03** Lines 340–346 vs 404–414  
+Same conflict for sequence diagrams: compact and expanded workflows both claim to be authoritative.
+
+**C-04** Lines 309 vs 323  
+Line 309: "CRITICAL: All diagram work REFINES skeletons from Step 3.3." Line 323 prohibited action: "Delete skeleton and create new diagram from scratch." But lines 329: "Exception: If skeleton is malformed, report error and request manual intervention." Conflict: what to do if skeleton is bad is unclear (request manual intervention ≠ any stated action path).
+
+**C-05** Lines 556–558 vs 560–569  
+Step 3.5 item 2 says "Construct, Verify, Write must be a single step — DO NOT split Build and Write". Item 3 is "Verify template compliance before writing" as a separate, listed item. This contradicts the single-step mandate by presenting verification as a separable step.
+
+---
+
+## Structural (S) — misplaced rules, no clear entry point, obscured structure
+
+**S-01** Lines 22–35 (before Step 0)  
+"Confirm analysis target" is an unnumbered step positioned before Step 0. It is effectively Step -1 but has no step number. A reader scanning step numbers misses it. Should be Step 0 or Step 1 with Step 0 renumbered.
+
+**S-02** Lines 608–621 ("Output template" section)  
+This section summarizes the template structure (7 bullet points). Step 3.1 already says "Read template file" and Step 3.4 inlines the examples. The section adds a 7-item list that duplicates Step 3.4's structure summary. Orphaned after the main process flow.
+
+**S-03** Lines 633–661 ("Best practices" section)  
+All 4 sub-sections restate rules already embedded in steps (see D-14 through D-17). The section provides no information not already in the steps; it exists only as a summary, but summaries at the end of workflow files invite the AI to skip the steps and read only the summary.
+
+**S-04** Lines 309–474 (Step 3.4 diagram instructions)  
+Class diagram instructions are split across: (a) compact refinement workflow, (b) permitted/prohibited actions, (c) "Dependency diagram Step 1/Step 2" expanded block, (d) "Key points" block. A reader trying to understand class diagram rules must synthesize 4 non-contiguous sub-blocks.
+
+**S-05** Lines 525–606 (Step 3.5)  
+The step has 5 numbered items but items 2–4 are described as a single operation ("Build and Write must be single step"). The numbering implies separability that the instructions then contradict.
+
+**S-06** Lines 663–685 ("Example execution" section)  
+The example re-narrates the steps at a high level. Useful as orientation but currently placed after "Best practices", making it the last thing in the file. As a reader orientation aid it belongs near the top (e.g., after the Overview).
+
+**S-07** Lines 88–91 (Step 1 Output line)  
+Step 1's Output sentence ("Target files list, dependency graph...") is listed as the last item under Step 1 but uses the same bullet style as the numbered sub-steps, making it visually indistinguishable from a sub-step.
+
+---
+
+## Verbose (V) — reducible without loss
+
+**V-01** Lines 55–63 (Step 0 IMPORTANT block)  
+Explains internal file-naming conventions (`.nabledge-code-analysis-id`, `UNIQUE_ID format`, epoch time) that are script internals. The LLM only needs to run the script; internal file naming is irrelevant to workflow execution.
+
+**V-02** Lines 193–205 (Step 3.2 parameter bullets)  
+`source-files` and `knowledge-files` each have 4 nearly identical sub-bullets ("Pass basenames only", "Script searches", "If multiple found", "Script handles"). The sub-bullets are a policy note that applies to both; stating it once at the parameter block level would suffice.
+
+**V-03** Lines 207–214 (Step 3.2 "Automatic behavior")  
+Describes what the script does automatically (output path, official docs). These are useful one-liners but are expanded into a block with headers and sub-bullets that adds length without adding clarity.
+
+**V-04** Lines 215–226 (Step 3.2 "Pre-filled placeholders 9/17")  
+Enumerating all 9 placeholder descriptions here is redundant with the template-guide which already defines them, and with the Step 3.5 list.
+
+**V-05** Lines 259–273 (Step 3.3 Error handling + Validation)  
+Script-level error-handling instructions (check stderr, common causes, verify parse errors) repeat the same pattern as Step 3.2's error-handling block. A single shared error-handling policy statement would be shorter.
+
+**V-06** Lines 283–286 (Step 3.3 Storage)  
+"Store class diagram output as CLASS_DIAGRAM_SKELETON in working memory... You will retrieve these skeletons in the following steps." The last sentence is obvious given that the next sections reference these variables.
+
+**V-07** Lines 292–307 (Step 3.4 output budget table)  
+Budget guideline table is useful, but the "When over budget" bullet block below it restates the same priority logic verbally. Either the table or the prose is sufficient.
+
+**V-08** Lines 486–519 (Output format examples)  
+The full Nablarch Usage structure example (ObjectMapper) occupies 34 lines. The template-guide already contains this example. Inlining the full example here duplicates the template-guide.
+
+**V-09** Lines 541–551 (Step 3.5 "Already pre-filled" block)  
+Lists 9 already-filled placeholders with descriptions. The reader just ran Step 3.2 which filled them; this list is a reminder that adds 11 lines without adding information.
+
+**V-10** Lines 576–583 (Step 3.5 Validation checkpoint)  
+File-size heuristic ("<5 KB likely missing content, >100 KB possible duplicate") is not actionable — the LLM cannot measure file size before writing. Remove or replace with a meaningful post-write check.
+
+**V-11** Lines 596–601 (Step 3.5 Step 5 IMPORTANT block)  
+Explains that finalize-output.sh "handles: session ID retrieval, duration calculation, and file update" — script internals not needed for correct invocation. The error-handling sub-point is worth keeping; the internal description is not.
+

+
+## Estimated line savings
+
+| Action | Savings (approx.) |
+|--------|------------------|
+| Remove compact refinement workflow (D-01, D-02, D-03, D-04) | ~35 lines |
+| Remove "Output template" section (S-02) | ~14 lines |
+| Remove "Best practices" section (D-14–D-17, S-03) | ~30 lines |
+| Compress Step 3.5 placeholder block (D-05, V-09) | ~20 lines |
+| Remove Step 3.2 sub-bullet redundancy (V-02, V-04) | ~18 lines |
+| Remove Nablarch Usage inline example (V-08) | ~30 lines |
+| Remove script-internal IMPORTANT blocks (V-01, V-11) | ~12 lines |
+| Merge error-handling blocks (V-05) | ~10 lines |
+| Remove "Example execution" or move to Overview (S-06) | ~23 lines |
+| Fix conflicts (C-01 example fix, C-05 step renumber) | ~5 lines |
+| Other verbose reductions (V-03, V-06, V-07, V-10) | ~15 lines |
+| **Total** | **~212 lines** |
+
+**Projected result**: 685 − 212 ≈ **473 lines** (before prose tightening)  
+With prose tightening across remaining sections: **~390–410 lines** — within ≤400 target.
