+- Skills are discovered from the fixed project-level `.agents/skills/` directory.
 - The runtime exposes two built-in skill tools: `activate_skill` and `read_skill_file`.
 - `read_skill_file` only works after the relevant skill has been activated.
-- Skill `SKILL.md` frontmatter may include optional `allowed-tools` using the Agent Skills spec format, for example `allowed-tools: run_python_script execute_code`.
+- Skill `SKILL.md` frontmatter may include optional `allowed-tools` using the Agent Skills spec format, for example `allowed-tools: execute_code`.
 - If a selected skill requires tools that are not bound on the node, that skill is skipped at runtime.
 - If no compatible skills remain, the agent is explicitly instructed not to claim skill usage.
