Example prompts

  • “Use Development OS to inspect this software project.”
  • “Use Development OS to shape this feature before implementation.”
  • “Use Development OS to audit and improve this codebase.”

Skills

  • development-os

    Automatically use as the session kernel for software and digital-product development work, including audits, architecture, implementation, debugging, provider operations, waits/resumption, and terse continuation. Own present intent, objective/constraints, stage/mode, authority, scoped authorization, referent-scoped liveness, capability routing, stewardship, guided human handoff, and fresh-context reconstruction; co-activate subordinate Development OS specialists when material.

  • evidence-stewardship

    Use with Development OS whenever development work materially depends on proof, uncertainty, tests, runtime/provider evidence, documentation authority, regressions, acceptance, or deciding what evidence deserves permanence. Development OS must remain active as the session kernel; Evidence Stewardship manages the transition from uncertainty to justified confidence.

  • founder-to-feature

    Use with Development OS when development work contains unresolved product meaning: substantial feature ideas, architecture-affecting behavior, workflow redesign, or audit findings that require deciding what should become true. Development OS must remain active as the session kernel; Founder-to-Feature owns Explore → Resolve → Crystallize → Ready for the semantic referent.

  • lean-repository-execution

    Use with Development OS for authorized implementation, debugging, refactoring, repository/provider operations, verification, and delivery. Development OS must remain active as the session kernel; Lean Repository Execution owns orientation, canonical-owner changes, mutation integrity, execution cadence, recovery, provider operations, and completion.

  • specialist-reasoning

    Use with Development OS when professional perspective or materially different representations could improve software/product work. Development OS must remain active as the session kernel; Specialist Reasoning selects the smallest sufficient professional team, reasons independently before synthesis, and returns only findings that materially change the owning workflow.
