skills_tool.py DOX

Purpose

• Own the skills_tool.py agent tool.
• This module searches, loads, and lists Agent Zero skills for the agent.
• Keep this file-level DOX profile synchronized with skills_tool.py because this directory is intentionally flat.

Ownership

• skills_tool.py owns the runtime implementation.
• skills_tool.py.dox.md owns durable notes about responsibilities, contracts, side effects, and verification for that implementation.
• Classes:
• SkillsTool (Tool)
  • get_log_object(self)
  • async before_execution(self, **kwargs)
  • async execute(self, **kwargs) -> Response
  • _visible_skill_loaded(self, skill_name: str) -> bool
• Top-level functions:
• max_loaded_skills() -> int
• Notable constants/configuration names: DATA_NAME_LOADED_SKILLS.

Runtime Contracts

• Tool modules must define helpers.tool.Tool subclasses and return helpers.tool.Response from execute(...).
• Update this file whenever tool arguments, output shape, break_loop behavior, intervention handling, prompt instructions, or side effects change.
• SkillsTool is a Tool.
• SkillsTool defines execute(...).
• Loading a skill appends the full skill body as a normal tool-result history message with skill_instructions metadata containing name, path, source, and content visibility.
• Loaded skill IDs are stored in chat-wide context data.
• Duplicate loads omit the full body when the same skill name remains visible in model history.
• Missing or empty action defaults to list, and legacy method is accepted as a deprecated alias when action is absent.
• Observed side-effect areas: filesystem reads, filesystem deletion, settings/state persistence, chat history persistence.
• Imported dependency areas include: __future__, helpers, helpers.print_style, helpers.tool, pathlib, typing.

Key Concepts

• Important called helpers/classes observed in the source: str.strip.lower.replace, skill_name.strip, super.get_log_object, self._normalize_skill_name, self.get_log_object, skills_helper.list_skills, join, skills_helper.search_skills, skills_helper.find_skill, skills_helper.load_skill_for_agent, skills_helper.add_loaded_skill_name, skills_helper.skill_instruction_name, skill.path.resolve, Path, resolved.read_text, skill_name.startswith, skill_name.endswith, self._current_action, self.agent.context.log.log, Response, strip, target.is_absolute.
• Keep request/response, tool, or helper semantics documented here at the same time as source changes.

Work Guidance

• Keep tool output concise, model-readable, and safe for history persistence.
• Coordinate argument or behavior changes with prompt tool instructions and skill guidance.
• Respect intervention flow for long-running, external, or user-visible operations.

Verification

• Run targeted tool and prompt-contract tests for changed behavior; smoke-test agent execution when no focused test exists.
• Related tests observed by source search:
  • tests/test_document_query_plugin.py
  • tests/test_tool_action_contracts.py
