YeonGyu-Kim a651e7f073 docs(agents): regenerate AGENTS.md hierarchy with init-deep
- Root: preserve 3 CRITICAL sections (PR target, OpenCode source, English-only)
- Update all 10 AGENTS.md files with current codebase analysis
- Add complexity hotspots, agent models, anti-patterns
- Sync line counts and structure with actual implementation

TOOLS KNOWLEDGE BASE

OVERVIEW

20+ tools across 7 categories. Two patterns: Direct ToolDefinition (static) and Factory Function (context-dependent).

Categories: LSP (6), AST-Grep (2), Search (2), Session (4), Agent delegation (2), Background (2), Skill (3)

TASK TOOLS

Claude Code compatible task management.

  • task_create: Creates a new task. Auto-generates ID and syncs to Todo.
    • Args: subject, description, activeForm, blocks, blockedBy, owner, metadata
  • task_get: Retrieves a task by ID.
    • Args: id
  • task_list: Lists active tasks. Filters out completed/deleted by default.
    • Args: status, parentID
  • task_update: Updates task fields. Supports additive addBlocks/addBlockedBy.
    • Args: id, subject, description, status, activeForm, addBlocks, addBlockedBy, owner, metadata

HOW TO ADD

  1. Create src/tools/[name]/ with standard files
  2. Use tool() from @opencode-ai/plugin/tool
  3. Export from src/tools/index.ts
  4. Static tools → builtinTools, Factory → separate export

TOOL PATTERNS

Direct ToolDefinition:

export const grep: ToolDefinition = tool({
  description: "...",
  args: { pattern: tool.schema.string() },
  execute: async (args) => result,
})

Factory Function (context-dependent):

export function createDelegateTask(ctx, manager): ToolDefinition {
  return tool({ execute: async (args) => { /* uses ctx */ } })
}

NAMING

  • Tool names: snake_case (lsp_goto_definition)
  • Functions: camelCase (createDelegateTask)
  • Directories: kebab-case (delegate-task/)

ANTI-PATTERNS

  • Sequential bash: Use && or delegation
  • Raw file ops: Never mkdir/touch in tool logic
  • Sleep: Use polling loops
