2025-12-04 16:58 - Task 1 Completed

Summary

• Created ~/.config/opencode/plugin/mcp-loader.ts - Plugin skeleton with config loader
• Created ~/.config/opencode/plugin/mcp-loader.test.ts - 14 unit tests

Key Implementation Details

• Config merge: project overrides global for same server names, merges different
• Env var substitution: {env:VAR} → process.env.VAR
• Validation: type required, local needs command, remote needs url
• Empty config returns { servers: {} } (not error)

Test Results

• 14 tests passed
• substituteEnvVars: 4 tests
• substituteHeaderEnvVars: 1 test
• loadConfig: 9 tests

Files Created

• ~/.config/opencode/plugin/mcp-loader.ts
• ~/.config/opencode/plugin/mcp-loader.test.ts

[2025-12-08 18:56] - Task 1: Remove unused import formatWorkspaceEdit from LSP tools

DISCOVERED ISSUES

• None - simple import cleanup task

IMPLEMENTATION DECISIONS

• Removed only formatWorkspaceEdit from import list at line 17
• Kept all other imports intact (formatCodeActions, applyWorkspaceEdit, formatApplyResult remain)
• Verified the function exists in utils.ts:212 but is truly unused in tools.ts

PROBLEMS FOR NEXT TASKS

• None identified for remaining tasks

VERIFICATION RESULTS

• Ran: bun run typecheck → exit 0, no errors
• Ran: bun run build → exit 0, bundled 200 modules
• Ran: rg "formatWorkspaceEdit" src/tools/lsp/tools.ts → no matches (confirmed removal)

LEARNINGS

• Convention: This project uses bun run typecheck (tsc --noEmit) and bun run build for verification
• The formatWorkspaceEdit function still exists in utils.ts - it's exported but just not used in tools.ts

[2025-12-08 19:00] - Task 2: Remove unused ThinkingPart interface and fallbackRevertStrategy function

DISCOVERED ISSUES

• None - both items were genuinely unused (no callers found)

IMPLEMENTATION DECISIONS

• Removed ThinkingPart interface (lines 37-40) - defined but never referenced
• Removed fallbackRevertStrategy function (lines 189-244) - defined but never called
• Added comment explaining removal reason as per task requirements
• Kept ThinkingPartType, prependThinkingPart, stripThinkingParts - these are different items and ARE used

PROBLEMS FOR NEXT TASKS

• None identified

VERIFICATION RESULTS

• Ran: bun run typecheck → exit 0, no errors
• Ran: bun run build → exit 0, bundled 200 modules
• Ran: rg "ThinkingPart" src/hooks/session-recovery/ → only related types/functions found, interface removed
• Ran: rg "fallbackRevertStrategy" src/hooks/session-recovery/ → only comment found, function removed
• Ran: rg "createSessionRecoveryHook" src/hooks/ → exports intact

LEARNINGS

• ThinkingPart interface vs ThinkingPartType type vs prependThinkingPart function - different entities, verify before removing
• fallbackRevertStrategy was likely a planned feature that never got integrated into the recovery flow

[2025-12-08 19:04] - Task 3: Remove unused builtinMcps export from MCP module

DISCOVERED ISSUES

• None - builtinMcps export was genuinely unused (no external importers)

IMPLEMENTATION DECISIONS

• Removed export const builtinMcps = allBuiltinMcps from line 24
• Kept allBuiltinMcps const - used internally by createBuiltinMcps function
• Kept createBuiltinMcps function - actively used in src/index.ts:89

PROBLEMS FOR NEXT TASKS

• None identified

VERIFICATION RESULTS

• Ran: bun run typecheck → exit 0, no errors
• Ran: bun run build → exit 0, bundled 200 modules
• Ran: rg "builtinMcps" src/mcp/index.ts → no matches (export removed)
• Ran: rg "createBuiltinMcps" src/mcp/index.ts → function still exists

LEARNINGS

• createBuiltinMcps function vs builtinMcps export - function is used, direct export is not
• Internal const allBuiltinMcps should be kept since it's referenced by the function

[2025-12-09 16:13] - Task 1: Add file-based logger to shared module

DISCOVERED ISSUES

• None - straightforward file copy and modification task

IMPLEMENTATION DECISIONS

• Copied logger.ts from opencode-cc-plugin source
• Changed log file path from opencode-cc-plugin.log to oh-my-opencode.log
• Added barrel export from src/shared/index.ts
• Kept original comment for module description

PROBLEMS FOR NEXT TASKS

• None identified - logger is now available for use in all new loaders

VERIFICATION RESULTS

• Ran: bun run typecheck → exit 0, no errors
• Log file path verified: /tmp/oh-my-opencode.log
• Exports verified: log() and getLogFilePath() now accessible via src/shared

LEARNINGS

• Source file location: ~/local-workspaces/opencode-cc-plugin/src/shared/logger.ts
• Logger uses fs.appendFileSync for synchronous file writing
• Empty catch block intentionally swallows errors to prevent logging from breaking main operations

[2025-12-09 16:14] - Task 3: Rename skill-loader to claude-code-skill-loader

DISCOVERED ISSUES

• None - straightforward directory rename task

IMPLEMENTATION DECISIONS

• Used mv command to rename src/features/skill-loader/ → src/features/claude-code-skill-loader/
• Updated import path in src/index.ts (lines 19-22)
• Did NOT modify internal imports (../command-loader/types) since command-loader still exists (Task 2 runs in parallel)

PROBLEMS FOR NEXT TASKS

• If Task 2 renames command-loader to claude-code-command-loader, the internal imports in claude-code-skill-loader will need to be updated as part of Task 2's scope
• The skill-loader's loader.ts:6 and types.ts:1 import from ../command-loader/types

VERIFICATION RESULTS

• Ran: bun run typecheck → exit 0, no errors
• Ran: bun run build → exit 0, succeeded
• Directory structure verified: skill-loader/ deleted, claude-code-skill-loader/ exists

LEARNINGS

• This project uses mv for directory rename (acceptable per ANTI-PATTERNS - file creation is forbidden, not rename)
• Command: bun run typecheck for type check, bun run build for build
• skill-loader internal imports use relative paths (../command-loader/types) which remain valid after rename

[2025-12-09 16:16] - Task 2: Rename command-loader to claude-code-command-loader

DISCOVERED ISSUES

• skill-loader (now claude-code-skill-loader) was importing CommandDefinition from ../command-loader/types
• After renaming command-loader, these references also needed updating

IMPLEMENTATION DECISIONS

• Used mv command: src/features/command-loader/ → src/features/claude-code-command-loader/
• Updated import path in src/index.ts (lines 13-18)
• Also updated claude-code-skill-loader/loader.ts:6 and types.ts:1 to reference new path

PROBLEMS FOR NEXT TASKS

• None identified - all dependent imports updated

VERIFICATION RESULTS

• Ran: bun run typecheck → exit 0, no errors
• Directory structure verified: command-loader/ deleted, claude-code-command-loader/ exists
• All imports updated: src/index.ts, claude-code-skill-loader/loader.ts, claude-code-skill-loader/types.ts

LEARNINGS

• skill-loader depends on command-loader's CommandDefinition type via relative import
• When renaming shared modules, must update ALL dependent modules' imports
• Task 2 and Task 3 have an implicit dependency through the type import

[2025-12-09 16:24] - Task 4: Add claude-code-agent-loader feature

DISCOVERED ISSUES

• None - straightforward file copy task

IMPLEMENTATION DECISIONS

• Copied 3 files from opencode-cc-plugin: index.ts, loader.ts, types.ts
• Import path ../../shared/frontmatter unchanged - already compatible with oh-my-opencode structure
• No log() usage in source files - no logger integration needed

PROBLEMS FOR NEXT TASKS

• None identified - agent-loader is self-contained

VERIFICATION RESULTS

• Ran: bun run typecheck → exit 0, no errors
• Directory structure verified: claude-code-agent-loader/ created with 3 files
• Functions exported: loadUserAgents(), loadProjectAgents()

LEARNINGS

• Source location: ~/local-workspaces/opencode-cc-plugin/src/features/agent-loader/
• Agent loader uses parseFrontmatter from shared module
• Agent configs loaded from ~/.claude/agents/ (user) and .claude/agents/ (project)
• Scope is appended to description: (user) or (project)

소요 시간: ~1분

[2025-12-09 16:25] - Task 5: Add claude-code-mcp-loader feature

DISCOVERED ISSUES

• None - straightforward file copy task

IMPLEMENTATION DECISIONS

• Copied 5 files from opencode-cc-plugin: index.ts, loader.ts, transformer.ts, env-expander.ts, types.ts
• Import path ../../shared/logger unchanged - already compatible with oh-my-opencode structure
• Kept Bun.file() usage - oh-my-opencode targets Bun runtime
• Environment variable expansion supports ${VAR} and ${VAR:-default} syntax

PROBLEMS FOR NEXT TASKS

• None identified - mcp-loader is self-contained
• Does NOT conflict with src/mcp/ (builtin MCPs are separate)

VERIFICATION RESULTS

• Ran: bun run typecheck → exit 0, no errors
• Directory structure verified: claude-code-mcp-loader/ created with 5 files
• Functions exported: loadMcpConfigs(), formatLoadedServersForToast(), transformMcpServer(), expandEnvVars(), expandEnvVarsInObject()

LEARNINGS

• Source location: ~/local-workspaces/opencode-cc-plugin/src/features/mcp-loader/
• MCP configs loaded from:
  • ~/.claude/.mcp.json (user scope)
  • .mcp.json (project scope)
  • .claude/.mcp.json (local scope)
• Later scope overrides earlier scope for same server name
• Supports stdio, http, and sse server types

[2025-12-09 16:24] - Task 6: Add claude-code-session-state feature

DISCOVERED ISSUES

• None - straightforward file copy task

IMPLEMENTATION DECISIONS

• Copied 4 files from opencode-cc-plugin: types.ts, state.ts, detector.ts, index.ts
• No import path changes needed - files are completely self-contained
• No external dependencies - types are defined locally

PROBLEMS FOR NEXT TASKS

• Task 7 should import from ./features/claude-code-session-state in src/index.ts
• Task 7 should remove local session variables and use the module's getter/setters

VERIFICATION RESULTS

• Directory created: src/features/claude-code-session-state/ (4 files confirmed)
• Exports available: sessionErrorState, sessionInterruptState, subagentSessions, sessionFirstMessageProcessed (Maps/Sets)
• Exports available: currentSessionID, currentSessionTitle, mainSessionID (state vars)
• Exports available: setCurrentSession(), setMainSession(), getCurrentSessionID(), getCurrentSessionTitle(), getMainSessionID() (getters/setters)
• Exports available: detectInterrupt() function

LEARNINGS

• Session state module is completely self-contained - no external dependencies
• Uses barrel export pattern: index.ts re-exports everything from types, state, detector
• Source directory: ~/local-workspaces/opencode-cc-plugin/src/features/session-state/

[2025-12-09 16:32] - Task 7: Integrate new features into src/index.ts

DISCOVERED ISSUES

• None - integration task with well-defined API from previous tasks

IMPLEMENTATION DECISIONS

• Added imports for new modules:
  • loadUserAgents, loadProjectAgents from ./features/claude-code-agent-loader
  • loadMcpConfigs from ./features/claude-code-mcp-loader
  • setCurrentSession, setMainSession, getMainSessionID, getCurrentSessionTitle from ./features/claude-code-session-state
  • log from ./shared/logger
• Removed local session variables (lines 77-79): mainSessionID, currentSessionID, currentSessionTitle
• Replaced direct session assignments with setter functions:
  • mainSessionID = x → setMainSession(x)
  • currentSessionID = x; currentSessionTitle = y → setCurrentSession(x, y)
• Replaced session variable reads with getter functions:
  • mainSessionID comparisons → getMainSessionID()
  • currentSessionTitle reads → getCurrentSessionTitle()
• Added agent loading in config hook: loadUserAgents(), loadProjectAgents()
• Added MCP loading in config hook: await loadMcpConfigs() (async)
• Replaced console.error with log() for config validation errors
• Renamed local variable agents to builtinAgents to distinguish from loaded agents

PROBLEMS FOR NEXT TASKS

• Task 8 (README update) should document the new Agent Loader and MCP Loader features
• Should explain the claude-code-* naming convention

VERIFICATION RESULTS

• Ran: bun run typecheck → exit 0, no errors
• Ran: bun run build → exit 0, successful build
• Session tracking verified: all event handlers use getter/setter functions
• Agent loading verified: config.agent merges builtin + user + project agents
• MCP loading verified: config.mcp merges builtin MCPs + loaded MCP servers

LEARNINGS

• setCurrentSession(id, title) sets both ID and title atomically
• loadMcpConfigs() is async - must use await in config hook
• MCP result has .servers property that returns the server configs
• Order matters in spread: later values override earlier (projectAgents > userAgents > builtinAgents)

[2025-12-09 16:35] - Task 8: Update README.md documentation

DISCOVERED ISSUES

• None - documentation update task

IMPLEMENTATION DECISIONS

• Added Agent Loader feature documentation under "Other Features" section (line 235-238)
  • User scope: ~/.claude/agents/
  • Project scope: ./.claude/agents/
  • Format: *.md files with YAML frontmatter
• Added MCP Loader feature documentation (line 239-243)
  • User scope: ~/.claude/.mcp.json
  • Project scope: ./.mcp.json
  • Local scope: ./.claude/.mcp.json
  • Environment variable expansion (${VAR} syntax)
• Added claude-code-* naming convention explanation as a blockquote note (line 245)
  • Explains features migrated from Claude Code
  • Lists examples: claude-code-command-loader, skill-loader, agent-loader, mcp-loader

PROBLEMS FOR NEXT TASKS

• None - this is the final task

VERIFICATION RESULTS

• README.md updated with new documentation
• Style matches existing documentation (bullet points, code blocks for paths)
• No sections removed or modified (only additions)

LEARNINGS

• README.md "Other Features" section is at line 224
• Existing features: Terminal Title, Command Loader, Skill Loader
• Documentation style: bold feature name, bullet points for scopes/details

[2025-12-09 17:24] - Task 0: Shared Utilities 포팅

DISCOVERED ISSUES

• command-executor.ts already existed but had minor whitespace differences (indentation inconsistency)
• pattern-matcher.ts and hook-disabled.ts import from ../claude-compat/types which doesn't exist yet in oh-my-opencode
• Types will be created in Task 1 at src/hooks/claude-code-hooks/types.ts

IMPLEMENTATION DECISIONS

• Created snake-case.ts and tool-name.ts (no dependencies) - exact copy from source
• Created temporary stub types at src/hooks/claude-code-hooks/types.ts with minimal definitions needed for shared utilities
• Created pattern-matcher.ts with adjusted import: ../claude-compat/types → ../hooks/claude-code-hooks/types
• Created hook-disabled.ts with adjusted import to point to stub types
• Added all new utilities to src/shared/index.ts using barrel export pattern
• Stub types include: HookCommand, HookMatcher, ClaudeHooksConfig, ClaudeHookEvent, PluginConfig

PROBLEMS FOR NEXT TASKS

• Task 1 will replace stub types with full implementation from opencode-cc-plugin
• Stub types in src/hooks/claude-code-hooks/types.ts are marked with comments indicating they're temporary
• The real PluginConfig will likely be different - current stub only supports disabledHooks field

VERIFICATION RESULTS

• Ran: bun run typecheck → exit 0, no errors
• All 5 functions exported: executeHookCommand, objectToSnakeCase, transformToolName, findMatchingHooks, isHookDisabled
• Import paths verified: pattern-matcher.ts and hook-disabled.ts successfully import from stub types

LEARNINGS

• Import paths must be adjusted when porting between different project structures
• opencode-cc-plugin structure: src/claude-compat/ → oh-my-opencode structure: src/hooks/claude-code-hooks/
• Stub types strategy allows Task 0 to complete and typecheck to pass before Task 1 implements full types
• command-executor.ts in oh-my-opencode had indentation inconsistency (not 100% identical to source)

[2025-12-09 17:34] - Task 1: types.ts 포팅

DISCOVERED ISSUES

• Stub types.ts had PluginConfig interface needed by hook-disabled.ts (from Task 0)
• Full types.ts from opencode-cc-plugin did NOT have PluginConfig
• Typecheck initially failed: Module has no exported member 'PluginConfig'

IMPLEMENTATION DECISIONS

• Copied full types.ts (181 lines) from opencode-cc-plugin → oh-my-opencode
• Preserved ALL types: ClaudeHooksConfig, HookMatcher, PreToolUseInput/Output, PostToolUseInput/Output
• Preserved deprecated decision fields: decision?: "allow" | "deny" | "approve" | "block" | "ask"
• Added PluginConfig interface at end (oh-my-opencode specific type needed by hook-disabled.ts)
• Kept line 150 comment (// "pending" | "in_progress" | "completed") - existing source comment

PROBLEMS FOR NEXT TASKS

• PluginConfig is now available for all subsequent tasks
• Full type definitions ready for Task 2, 3, 4+ to use

VERIFICATION RESULTS

• Ran: bun run typecheck → exit 0, no errors
• Verified: ClaudeHooksConfig, HookMatcher, HookCommand types exist
• Verified: PreToolUseInput/Output, PostToolUseInput/Output types exist
• Verified: deprecated decision field (approve/block) included in PreToolUseOutput
• Verified: PluginConfig export added (fixes hook-disabled.ts import)

LEARNINGS

• opencode-cc-plugin types.ts: 181 lines, no PluginConfig
• oh-my-opencode requires PluginConfig for hook disabling functionality
• Stub-to-full replacement pattern works: stub allows Task 0 typecheck, Task 1 replaces with full implementation
• Must preserve project-specific types (PluginConfig) when porting from different codebases

[2025-12-09 17:39] - Task 3: tool-input-cache.ts 포팅

DISCOVERED ISSUES

• None - straightforward file copy task

IMPLEMENTATION DECISIONS

• Copied tool-input-cache.ts (48 lines) from opencode-cc-plugin → oh-my-opencode
• Preserved cache structure:
  • Key format: ${sessionId}:${toolName}:${invocationId}
  • TTL: 60000ms (1 minute) as CACHE_TTL constant
  • Periodic cleanup: setInterval every CACHE_TTL (60000ms)
• Preserved original comments from source file (lines 12, 39)
• Functions: cacheToolInput(), getToolInput()
• Cache behavior: getToolInput() deletes entry immediately after retrieval (single-use cache)

PROBLEMS FOR NEXT TASKS

• Task 4 (pre-tool-use.ts) will call cacheToolInput() to store tool inputs
• Task 5 (post-tool-use.ts) will call getToolInput() to retrieve cached inputs for transcript building
• No import path changes needed - this file has no external dependencies

VERIFICATION RESULTS

• File created: src/hooks/claude-code-hooks/tool-input-cache.ts (48 lines)
• Functions exported: cacheToolInput(), getToolInput()
• TTL verified: CACHE_TTL = 60000 (1 minute)
• Cleanup interval verified: setInterval(cleanup, CACHE_TTL)

LEARNINGS

• Tool input cache is a temporary storage for PreToolUse → PostToolUse communication
• Single-use pattern: getToolInput() deletes entry after first retrieval (line 33)
• TTL check happens after deletion, so expired entries still return null
• setInterval runs in background for periodic cleanup of abandoned entries
• Source location: ~/local-workspaces/opencode-cc-plugin/src/claude-compat/hooks/tool-input-cache.ts

[2025-12-09 17:39] - Task 2: config.ts + transcript.ts + todo.ts 포팅

DISCOVERED ISSUES

• transcript.ts had unused imports (ClaudeCodeMessage, ClaudeCodeContent) - same as source file
• LSP warned about unused types - removed from import to clean up

IMPLEMENTATION DECISIONS

• Copied config.ts (101 lines) - no import path changes needed (only uses ./types and Node.js builtins)
• Copied transcript.ts (256 lines) - changed import path:
  • Line 10: ../shared/tool-name → ../../shared/tool-name (opencode-cc-plugin depth 1, oh-my-opencode depth 2)
• Copied todo.ts (78 lines) - no import path changes needed (only uses ./types and Node.js builtins)
• Removed unused imports from transcript.ts: ClaudeCodeMessage, ClaudeCodeContent (not used in function bodies)
• Preserved ALL original comments from source files - these are pre-existing comments

PROBLEMS FOR NEXT TASKS

• Task 3 will import cacheToolInput/getToolInput for cache functionality
• Task 4 will import loadClaudeHooksConfig, buildTranscriptFromSession
• Task 5 will import transcript building functions for PostToolUse hook

VERIFICATION RESULTS

• Ran: bun run typecheck → exit 0, no errors
• Files created: config.ts (101 lines), transcript.ts (256 lines), todo.ts (78 lines)
• Functions available: loadClaudeHooksConfig(), buildTranscriptFromSession(), appendTranscriptEntry(), loadTodoFile(), saveTodoFile()
• Import paths verified: transcript.ts successfully imports transformToolName from ../../shared

LEARNINGS

• Import path depth difference: opencode-cc-plugin src/claude-compat/ (1 level up) → oh-my-opencode src/hooks/claude-code-hooks/ (2 levels up)
• transcript.ts unused imports were present in original source - cleaning them is optional but improves code hygiene
• config.ts uses Bun.file() for async file reading - compatible with oh-my-opencode's Bun runtime
• Bun.file().text() automatically handles encoding
