Module tools 

Assembles the process_tools registry.

The tools grouped here (bash / fs / fetch / search / skill / spawn_agent, etc.) are mounted once on a StaticToolRegistry as the process_tools of an AgentCore instance, shared across all sessions of that core — not a process-global singleton (when using defect as a library, a single process may have multiple AgentCore instances, each with its own copy). MCP tools go through the session-level McpToolFactory assembled in the mcp_servers module.

Structs

ProfileHookBuildError

Hook engine build failed for a subagent profile; include the profile name for identification.

Functions

build_process_tools

Assembles the process_tools tool set from the [tools] section (shared across sessions for a given AgentCore instance).

build_process_tools_with_subagents

Assembles the process tool set, overlaying spawn_agent and skill tools when profiles or skills are present.

filter_tools_by_allowlist

Filters the base tool set to a subset according to an allowlist, for use with the top-level --profile (which runs the entire session as a single profile). Unknown tool names are a hard error (fail loud). spawn_agent is excluded even if present in the allowlist — a top-level profile is a leaf agent and does not spawn child agents.

project_skills

Project SkillSpec from defect-config into the agent-side SkillEntry, mirroring the cross-crate assembly-boundary projection pattern used in project_profiles.
