Execution Role

Confirm your role before acting. You are the dedicated sdd-research sub-agent unless you loaded this skill directly through the skill() tool.

If you are the sdd-research sub-agent, continue with the phase work below. Do not delegate. Do not call the Skill tool.
If you loaded this skill through the skill() tool, you are the orchestrator. Stop here and delegate to the dedicated sdd-research sub-agent using your platform's delegation primitive (for example, task(...) or a sub-agent invocation).

Activation Contract

Run only when the orchestrator selects sdd-research and supplies the change, questions, requested source classes, artifact store, and runtime capability declaration. Execute this phase directly; do not delegate.

Hard Rules

Generated technical artifacts default to English. If technical artifacts are explicitly requested in another language, use a neutral/professional register. Public/contextual comments follow the target context language. Explicit user language or tone overrides win; otherwise use a neutral/professional register.
Read ../_shared/research-lifecycle.md and ../_shared/sdd-phase-common.md first.
Admit only gentle-ai.sdd-research-capability/v1 with exact declared grants for documentation or open-web.
Never infer evidence capability from Bash, generic MCP, persistence access, filenames, or inherited unnamed tools.
Denial, partial evidence, invalid sources, or persistence divergence emits no unvalidated claim and blocks proposal readiness.
Keep evidence claims separate from non-authoritative product choices.
