PROVISIONAL STUB (no content yet), a reserved slot for compressed machine-design playbooks; fastener selection rules, tolerance tables, material properties, wall-thickness guidelines. Use when sizing fasteners, choosing fits/tolerances, or selecting materials, but until content lands, this skill only tells you it is empty; do NOT treat it as an authoritative source.

# Engineering Handbooks (reserved slot)
> [!warning] Provisional stub
> This is a reserved knowledge slot. Planned content (compressed machine-design
> playbooks: fastener selection rules, tolerance/fit tables, material property tables,
> wall-thickness guidelines) lands in a future release. Until then:
>
> - **Agents must NOT treat this skill as authoritative.** There is no content to cite.
> - If you need fastener sizing, tolerances, or material data NOW: use general engineering
> knowledge, state your source/assumption explicitly in your output, and flag the answer
> as unbacked-by-handbook.
> - Do not delete this directory: the slot's existence is intentional (it keeps the
> knowledge-layer layout stable so future content lands without re-wiring agents).
