`allowed-tools` in commands is an auto-approval mechanism only — unlisted tools are still callable (user is prompted, or silent under bypassPermissions). It is not a capability boundary. `tools:` in subagent frontmatter is a hard restriction — unlisted tools are genuinely unavailable even under bypassPermissions. Confusing the two is a security footgun documented in issue anthropics#65770. This commit adds a dedicated comparison section to tool-usage.md, updates the agent configuration example to show `tools:` usage, and adds a warning callout in SKILL.md at the point where `allowed-tools` is introduced.
