CLI Module Codemap

Responsibility

src/cli/ provides the plugin installation workflow and the utilities that generate and persist runtime configuration.

Current responsibilities:

• parse/install command arguments
• install-time validation and environment checks
• OpenCode configuration mutation (atomic)
• lite config generation for provider/agent presets
• optional skill installation and bundled-skill copying

Design

Command surface

• src/cli/index.ts only dispatches:
  • install subcommand and flags
  • --skills=yes|no
  • --preset=<name>
  • --no-tui
  • --dry-run
  • --reset
  • --help

The CLI is intentionally non-interactive-only now; it prints usage and steps to stdout with exit codes.

Module decomposition

• paths.ts: config directory and file discovery (opencode.json/.jsonc, lite config path).
• config-io.ts: JSON/JSONC parsing, normalize write behavior, atomic writes (.tmp + .bak), plugin registration, default-agent disabling.
• providers.ts: provider model mapping + generateLiteConfig().
• system.ts: OpenCode binary/version/path checks.
• skills.ts: bundled and permission-only skill permission defaults.
• custom-skills.ts: bundled skill registry and copy-to-config-directory implementation.
• config-manager.ts: re-export barrel for CLI config utilities.
• install.ts: end-to-end install orchestration and console messaging.
• types.ts: install/config DTOs.

Flow

CLI install command
  └─> install.ts (runInstall)
      1) check OpenCode installed
      2) add plugin entry to main OpenCode config
      3) disable legacy default agents
      4) write/preview generated lite config
      5) optional install phase:
         - installCustomSkill(...) for each CUSTOM_SKILL

generateLiteConfig(installConfig) behavior:

• sets $schema, a selected preset that defaults to openai
• always materializes generated presets openai and opencode-go
• install-time --preset only selects between generated presets
• maps each built-in agent name to provider-specific model/variant
• injects skill list from bundled custom skill registries
• injects default MCP sets from DEFAULT_AGENT_MCPS
• includes tmux block (layout, main_pane_size) when enabled

writeLiteConfig() writes target file atomically and supports --reset/dry-run branching in install.ts.

Runtime integration

• Output file produced by install (oh-my-opencode-slim.json) is consumed by runtime config/loader.ts.
• Permission defaults for installed/available skills are shared with agents/index.ts via cli/skills.ts.
• Generated provider/multiplexer settings are consumed by OpenCode session runtime via src/index.ts bootstrap.

Notes for architecture/docs accuracy

• The previous TUI references are stale; no dedicated interactive flow exists in current sources.
• --skills controls bundled/custom skill installation only.
• Built-in preset support includes openai, opencode-go, kimi, copilot, and zai-plan.
