* Add threat-model-analyst skill: STRIDE-A threat modeling for repositories Add a comprehensive threat model analysis skill that performs security audits using STRIDE-A (STRIDE + Abuse) threat modeling, Zero Trust principles, and defense-in-depth analysis. Supports two modes: - Single analysis: full STRIDE-A threat model producing architecture overviews, DFD diagrams, prioritized findings, and executive assessments - Incremental analysis: security posture diff between baseline report and current code, producing standalone reports with embedded comparison Includes bundled reference assets: - Orchestrator workflows (full and incremental) - Analysis principles and verification checklists - Output format specifications and skeleton templates - DFD diagram conventions and TMT element taxonomy * Address PR review comments from Copilot reviewer - Fix SKILL.md description: use single-quoted scalar, rename mode (2) to 'Incremental analysis' with accurate description - Replace 'Compare Mode (Deprecated)' sections with 'Comparing Commits or Reports' redirect (no deprecated language for first release) - Fix skeleton-findings.md: move Tier 1 table rows under header, add CONDITIONAL-EMPTY block after END-REPEAT (matching Tier 2/3 structure) - Fix skeleton-threatmodel.md and skeleton-architecture.md: use 4-backtick outer fences to avoid nested fence conflicts with inner mermaid fences - Fix skeleton-incremental-html.md: correct section count from 9 to 8 - Fix output-formats.md: change status 'open' to 'Open' in JSON example, move stride_category warning outside JSON fence as blockquote - Fix incremental-orchestrator.md: replace stale compare-output-formats.md reference with inline color conventions - Regenerate docs/README.skills.md with updated description * Address second round of Copilot review comments - Fix diagram-conventions.md: bidirectional flow notation now uses <--> matching orchestrator.md and DFD templates - Fix tmt-element-taxonomy.md: normalize SE.DF.SSH/LDAP/LDAPS to use SE.DF.TMCore.* prefix consistent with all other data flow IDs - Fix output-formats.md: correct TMT category example from SQLDatabase to SQL matching taxonomy, fix component type from 'datastore' to 'data_store' matching canonical enum, remove DaprSidecar from inbound_from per no-standalone-sidecar rule - Fix 5 skeleton files: clarify VERBATIM instruction to 'copy the template content below (excluding the outer code fence)' to prevent agents from wrapping output in markdown fences - Genericize product-specific names in examples: replace edgerag with myapp, BitNetManager with TaskProcessor, AzureLocalMCP with MyApp.Core, AzureLocalInfra with OnPremInfra, MilvusVectorDB with VectorDB * Address third round of Copilot review comments - Fix diagram-conventions.md: second bidirectional two-arrow pattern in Quick Reference section now uses <--> - Fix incremental-orchestrator.md: renumber HTML sections 5-9 to 4-8 matching skeleton-incremental-html.md 8-section structure - Fix output-formats.md: add incremental-comparison.html to File List as conditional output for incremental mode - Fix skeleton-inventory.md: add tmt_type, sidecars, and boundary_kind fields to match output-formats.md JSON schema example

**NEVER change these fixed elements:**
|
|
- `%%{init:` themeVariables: only `background`, `primaryColor`, `lineColor`
|
|
- `flowchart LR` — never TB
|
|
- classDef colors: process=#6baed6/#2171b5, external=#fdae61/#d94701, datastore=#74c476/#238b45
|
|
- Incremental classDefs (when applicable): newComponent=#d4edda/#28a745 (light green), removedComponent=#e9ecef/#6c757d (gray dashed)
|
|
- New components MUST use `:::newComponent` (NOT `:::process`). Removed components MUST use `:::removedComponent`.
|
|
- Trust boundary style: `fill:none,stroke:#e31a1c,stroke-width:3px,stroke-dasharray: 5 5`
|
|
- linkStyle: `stroke:#666666,stroke-width:2px`
|
|
|
|
**DFD shapes:**
|
|
- Process: `(("Name"))` (double parentheses = circle)
|
|
- Data Store: `[("Name")]` (bracket-paren = cylinder)
|
|
- External: `["Name"]` (brackets = rectangle)
|
|
- All labels MUST be quoted in `""`
|
|
- All subgraph IDs: `subgraph ID["Title"]`
|
|
|
|
<!-- ⛔ POST-DFD GATE — IMMEDIATELY after creating this file:
|
|
1. Count element nodes: lines with (("...")), [("...")], ["..."] shapes
|
|
2. Count boundaries: lines with 'subgraph'
|
|
3. If elements > 15 OR boundaries > 4:
|
|
→ OPEN skeleton-summary-dfd.md and create 1.2-threatmodel-summary.mmd NOW
|
|
→ Do NOT proceed to 1-threatmodel.md until summary exists
|
|
4. If threshold NOT met → skip summary, proceed to 1-threatmodel.md
|
|
This is the most frequently skipped step. The gate is MANDATORY. -->
