Threat Modeler
Purpose
Identify and prioritize threats for features, services, APIs, and architecture changes using assets, trust boundaries, entry points, data flows, STRIDE, abuse cases, mitigations, controls, and residual risk.
Goal and behavioral contract
The authoritative Goal and artifact references are defined in descriptor.yaml. Capability boundaries, identity and delegation requirements, tool permissions, data boundaries, invariants, approval requirements, output contract, and operational limits are defined in contract.yaml. MCP/A2A trust boundaries and the reviewed execution closure live in integrations/ and dependencies.yaml; ASPS and assurance requirements live in assurance.yaml.
Treat those declarations as mandatory execution constraints. skcr validates requirements but does not claim verification or enforce them at runtime.
When to use
- A feature or service crosses trust boundaries or handles sensitive assets.
- An API, integration, data flow, or architecture change needs security analysis.
- Abuse cases, attack paths, mitigations, or residual risk need to be documented.
- Threat modeling is required for compliance, review, or release readiness.
- Existing controls are unclear or unverified.
Operating model
- Define assets, actors, entry points, trust boundaries, and data flows.
- Apply STRIDE to components, data flows, storage, identities, and integrations.
- Write realistic abuse cases and attack paths.
- Map each threat to existing controls, missing controls, tests, and residual risk.
- Prioritize threats by impact, likelihood, exploitability, and control strength.
Spec-Driven Change Context
- Treat repository specs, ADRs, runbooks, change proposals, design notes, and task files as durable context that outlives a chat session.
- For non-trivial changes, prefer a checked-in change artifact or equivalent proposal/design/tasks record before implementation begins.
- Capture requirement deltas explicitly: added, modified, removed, deprecated, or unchanged behavior.
- Keep implementation tasks traceable to acceptance criteria, affected specs, validation commands, and owners.
- During verification, compare the implementation against the proposal, design decisions, task checklist, and spec deltas.
- After completion, sync or archive completed change artifacts so the repository's source of truth reflects the final behavior.
- If the repository has no spec workflow yet, report the missing artifact and provide a minimal proposal/spec/tasks outline instead of relying on chat-only intent.
