[BUG] - Agent frontmatter is not translated to the target's native dialect

[trevor-vaughan]

Bug Description

Summary

Agents authored in one assistant's frontmatter dialect leak that dialect into other targets. OpenCode-style frontmatter (mode: subagent, tools as a {name: bool} map) passes through unchanged to Claude Code, which expects tools as a comma-separated string and has no mode field. The agent installs with frontmatter the target cannot fully parse.

Expected

tools renders in the target's native form. Dialect-only fields are dropped for targets that don't understand them. For Claude Code:

tools: Read, Bash

mode and temperature are stripped.

Actual

The OpenCode tools map and mode: subagent write verbatim into the Claude Code agent file. Claude Code reads tools as a string, so the map is malformed, and mode is meaningless. The tool allowlist does not take effect.

Root cause

_generate_agent_with_frontmatter (src/lola/targets/base.py) copies the authored frontmatter and adds only the per-target fields (name, model: inherit for Claude Code and Cursor; mode: subagent for OpenCode). It never normalizes tools or removes fields foreign to the destination dialect.

Proposed Fix

Normalize the tools field on read (accept an OpenCode {name: bool} map, a Claude comma-separated string, or a list), then render per target:

• claude-code / cursor: comma-separated string of enabled tools in Claude tool names, with OpenCode-only mode and temperature fields stripped.
• opencode: {name: bool} map (Claude strings convert back to map form).

Steps to Reproduce

1. Author an agent with OpenCode-dialect frontmatter:

   ---
   description: Example agent
   mode: subagent
   tools:
     read: true
     bash: true
     write: false
   ---

2. lola install <module> -a claude-code.

3. Inspect the generated .claude/agents/<agent>.md frontmatter.
