* 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
