skill-author/agent-author's #89 retarget needs to know exactly how each .apm/ primitive compiles to Claude Code and Copilot CLI output. The existing microsoft-apm corpus only had a full schema for skills and one minimal example for agents, and nothing for prompts/instructions/hooks. Deepened via APM's own Python source (not just docs) where prose was thin. Key finding for #89: agents have no per-target integrator, so apm compile does a naive verbatim copy to both Claude and Copilot, unlike prompts/instructions/hooks which each get real per-target reconstruction. That means the agent primitive's `tools:` field can't express both harnesses' incompatible vocabularies at once — a real upstream gap, not something we can schema our way around.
