* 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

Install a Plugin
For most users, the Awesome Copilot marketplace is already registered in the Copilot CLI/VS Code, so you can install a plugin directly:
copilot plugin install <plugin-name>@awesome-copilot
If you are using an older Copilot CLI version or a custom setup and see an error that the marketplace is unknown, register it once and then install:
copilot plugin marketplace add github/awesome-copilot
copilot plugin install <plugin-name>@awesome-copilot
