v3.0.4 (Latest)
Release Date: 2026-08-21 | Base Version: v3.0.3
2.1 New Features
| Module | Details |
|---|---|
| SAD specification book generation skill | Added SAD specification book generation capability (sad-generation); inputs a Simulink Web View model package and optional BEV C code, automatically generates the complete content of the "4.1.1.X. <element_name>" page in the SAD template, trigger word "SAD" |
| SAD specification book generation skill | M1 I/F table construction: unit tree construction (including partition evidence), component-level "I/F情報" nine-column data generation, per-node architecture diagram drawing, structural supplement diagram generation, and optional cross-model link analysis and element-level cross-model structure diagram |
| SAD specification book generation skill | M2 task splitting: splits tasks by model into self-contained task files, and pre-fills determinable cells according to ELS-SAD design rules |
| SAD specification book generation skill | M3 description generation: concurrently generates Japanese description text by model, responsible only for the semantic parts that rules cannot determine (成立時／不成立時 narratives, minimum-unit algorithm direction, etc.) |
| SAD specification book generation skill | M4 deterministic merge gate: recalculates pre-filled results with scripts and performs verbatim comparison, marks the generation source of each cell, and outputs a rule report before failing when rule validation is not passed, eliminating non-compliant deliverables |
| SAD specification book generation skill | M5 deliverable aggregation: creates the "4.1.1.X. <element_name>" page and writes in order the element-level architecture diagram, "SWコンポーネント説明" table, element-level "I/F情報" table, per-node component architecture diagrams and supplement diagrams, "サブコンポーネント説明" table, and component-level "I/F情報" table |
| SAD specification book generation skill | Built-in deterministic toolset: SVG graphic analysis and link tracing (entry/exit/intermediate graphic tracing, direct link identification, IF branch tracing), model block diagram drawing, structural supplement diagram construction, SVG dashed bounding, cross-model structure diagram construction, I/F table construction, node derivation and unit localization |
| SUD specification book generation skill | Added generation capability for "SWユニットの説明", "処理", and the "解説" section of the 4.1.1 detail page, adopting a three-stage approach of "rule pre-fill + AI completion + deterministic gate validation"; content determinable by rules is not handed over to AI generation |
| SUD specification book generation skill | Added automatic signal attribute filling: automatically derives the contents of the "安全機能", "型", "最小値", "最大値", "単位", "LSB", "備考" columns based on the parameter card |
| SUD specification book generation skill | Added link splitting support for slwebview-format SVG; the SVG splitting tool automatically recognizes both Simulink and slwebview formats and dispatches processing accordingly |
| SUD specification book generation skill | Added in-diagram submodule replacement capability: gated subsystems can be replaced with adaptive-width "実行要求" capsule graphics, automatically matched by wiring direction |
| SUD specification book generation skill | Added a cutoff-graphic parameter to the SVG upstream tracing tool, allowing the tracing endpoint to be specified; cutoff graphics are not counted as intermediate graphics |
| SUD specification book generation skill | Added failed-instance reset capability; after confirming that a failure originates from a transient platform-side fault, only the failed instances can be re-run without affecting completed instances |
| General workflow engine | Consolidated a business-decoupled general declarative workflow engine reference implementation, including engine scripts, workflow configuration Schema, a business logic authoring guide, and three sample projects: sequential pipeline / loop / loop + fan-out |
2.2 Changes
| Module | Details |
|---|---|
| SUD specification book generation skill | The M2 stage is merged from 6 sub-steps into a single-step pipeline; deterministic stages without AI inference execute serially within the same process, and per-node processing is switched to thread-pool concurrency, reducing scheduling round-trip overhead |
| SUD specification book generation skill | Adjusted the deliverable directory layout: the delivery directory retains only final deliverables, intermediate outputs are consolidated by stage into independent run directories, and all outputs of the same workflow round share the same timestamp |
| SUD specification book generation skill | Unit partition rule adjustment: basic leaf nodes that output only a single signal are no longer split; derived nodes include only input/output signals with no intermediate process |
| SUD specification book generation skill | Signal name processing optimization: filters Simulink auto-generated block names (Constant/Merge/Sum/Terminator, etc.); calibration variable classification is now determined based on signal directory attributes |
| SUD specification book generation skill | Appended a "(前回値)" suffix to UnitDelay feedback signal descriptions; removed the trailing version number from hierarchy levels in the output tree structure |
| SAD specification book generation skill | The "サブコンポーネント説明" table now connects to the "SWユニット" column for minimum-unit determination; subcomponent names are changed from short names to full names consistent with the "I/F情報" link endpoints |
| SAD specification book generation skill | Optimized the drawing and presentation effects of model block diagrams and link diagrams |

2.4 Bug Fixes
| Module | Details |
|---|---|
| SUD specification book generation skill | Fixed an issue where line wrapping in the attribute card caused long fields such as "Description" to be truncated; continuation lines are now recognized by geometric position and concatenated correctly |
| SUD specification book generation skill | Fixed an issue where the workflow engine returned exit code 0 regardless of success or failure, causing the failure guard to never trigger |
| SUD specification book generation skill | Fixed an issue where the deliverable aggregation stage validated the existence of intermediate outputs using wildcards; changed to per-item named validation to avoid misusing historical residual files |
| SUD specification book generation skill | Fixed an issue where slwebview-format SVG splitting directly terminated the entire instance when no input block was found |
| SAD specification book generation skill | Fixed issues with duplicate-name links, duplicate model names, and identical signals across nodes being unrecognizable |
| SAD specification book generation skill | Fixed missing execution_condition cell box selection and Merge box overlap in the supplement diagrams |
| SAD specification book generation skill | Fixed the timestamp validation issue and unified the artifact timestamp criteria |
v3.0.3
