Config File Location User's Claude Code config is stored at: ```text ~/ghq/github.com/i9wa4/dotfiles/config/claude/ ``` Key files: - `settings.json` - Main settings - `CLAUDE.md` - Persona and core rules - `rules/` - Detailed rules (auto-loaded at startup) - `skills/` - Specialized knowledge (loaded on demand) - `agents/` - Custom agents - `commands/` - Slash commands ## 2. Fetch CHANGELOG Use `gh` command to fetch the latest CHANGELOG: ```sh gh api repos/anthropics/claude-code/contents/CHANGELOG.md \ --jq '.content' | base64 -d > .i9wa4/tmp/claude-code-changelog.md ``` Then read the file to analyze. ## 3. CHANGELOG Operations ### 3.1. Latest Release Summary 1. Fetch CHANGELOG using the command above 2. Extract the first `## x.x.x` section 3. Categorize changes into: - New features (Added) - Bug fixes (Fixed) - Improvements (Improved/Changed) - Deprecations (Deprecated) 4. Present in Japanese with brief explanations ### 3.2. Version Diff 1. Ask user for start and end versions 2. Extract all sections between those versions 3. Summarize cumulative changes 4. Highlight breaking changes and deprecations ### 3.3. Breaking Changes Detection 1. Search for keywords: `Deprecated`, `Removed`, `Breaking`, `Changed` 2. List affected settings and migration paths 3. Check user's config for affected settings ## 4. Specification Reference For detailed questions about Claude Code specifications, features, and usage: - YOU MUST: Use the `claude-code-guide` subagent via Task tool - Example queries: hooks, MCP servers, settings, IDE integrations ```text Task tool with subagent_type: claude-code-guide ``` ## 5. Settings Categories | Category | Examples | | -------- | ----------------------------------- | | Display | `showTurnDuration`, `language` | | Behavior | `respectGitignore`, `autoUpdate` | | Tools | `disallowedTools`, `allowedTools` | | MCP | MCP server configurations | | Hooks | PreToolUse, PostToolUse, Stop hooks | | Plans | `plansDirectory` | ## 6. CLAUDE.md Design Guidelines - YOU MUST: Focus only on persona and core guidelines - YOU MUST: Split detailed rules into `rules/` - NEVER: Include unnecessary information at startup (reference links, usage details) ## 7. Configuration Usage | Type | Load Timing | Purpose | | ------------------ | ------------------------------ | ----------------------------- | | CLAUDE.md / rules/ | Full load at startup | Global rules always applied | | commands/ | Explicit user invocation | Predefined prompts, workflows | | skills/ | Auto-triggered by conversation | Specialized knowledge | | agents/ | Delegated via Task tool | Independent context | ## 8. Optimization Checklist Check the following when editing CLAUDE.md: - [ ] Is the persona definition concise? - [ ] Are basic rules truly needed at all times? - [ ] Can detailed explanations be moved to rules/ or skills/? - [ ] Have reference links been moved to skills/? ## 9. File Structure Maintenance When adding/removing files in rules/, skills/, agents/, or commands/: - YOU MUST: Update corresponding table in CLAUDE.md section 4 - YOU MUST: Keep tables alphabetically sorted or logically grouped - IMPORTANT: Verify actual files match documentation after changes ## 10. Optimization Tracking Last reviewed Claude Code version: v2.1.31 (2026-02-04) ### 10.1. Applied Optimizations - [x] Persona definition minimized - [x] Rules split into rules/ directory - [x] Skills split into skills/ directory - [x] Agents split into agents/ directory - [x] Commands split into commands/ directory - [x] Reference links moved to skills - [x] `language` setting - set to "follow CLAUDE.md's instructions" - [x] `mcpToolSearch` setting - set to "auto:1" - [x] `ENABLE_TOOL_SEARCH` env - set to "true" (force enable) - [x] `plansDirectory` setting - set to ".i9wa4/plans" ### 10.2.

Reference Links Official Documentation: - Best Practices: - Docs Map: Community Resources: - Claude Code config: - CLAUDE.md minimization: - site2skill: ## 14. Permission System Reference ### 14.1. Permission Modes | Mode | Description | | ------------------- | ----------------------------------------------------- | | `default` | Prompts for permission on first use of each tool | | `acceptEdits` | Auto-accepts file edit permissions for the session | | `plan` | Plan Mode: analyze only, no modifications | | `dontAsk` | Auto-denies unless pre-approved via allow rules | | `bypassPermissions` | Skips all prompts (use only in isolated environments) | ### 14.2. Rule Evaluation Order Rules are evaluated: **deny -> ask -> allow**. First matching rule wins. ### 14.3. Bash Wildcard Patterns ```json { "permissions": { "allow": [ "Bash(npm run *)", "Bash(git commit *)", "Bash(* --version)", "Bash(* --help *)" ], "deny": ["Bash(git push *)"] } } ``` NOTE: Space before `*` matters: `Bash(ls *)` matches `ls -la` but not `lsof`. ### 14.4. Read/Edit Path Patterns | Pattern | Meaning | Example | | -------- | ----------------------------- | ------------------------ | | `//path` | Absolute path from root | `Read(//Users/alice/**)` | | `~/path` | Path from home directory | `Read(~/.zshrc)` | | `/path` | Relative to settings file | `Edit(/src/**/*.ts)` | | `path` | Relative to current directory | `Read(*.env)` | NOTE: `*` matches single directory, `**` matches recursively. ### 14.5. MCP and Task Permissions ```json { "permissions": { "allow": ["mcp__puppeteer__*"], "deny": ["Task(Explore)"] } } ``` ### 14.6. Managed Settings Locations | Platform | Path | | --------- | --------------------------------------------------------------- | | macOS | `/Library/Application Support/ClaudeCode/managed-settings.json` | | Linux/WSL | `/etc/claude-code/managed-settings.json` | | Windows | `C:\Program Files\ClaudeCode\managed-settings.json` | ### 14.7. Managed-Only Settings | Setting | Description | | --------------------------------- | --------------------------------------- | | `disableBypassPermissionsMode` | Set to "disable" to prevent bypass mode | | `allowManagedPermissionRulesOnly` | Only managed rules apply | | `allowManagedHooksOnly` | Only managed/SDK hooks allowed | ## 15. Insights-Based Recommendations Based on usage analysis (55K messages, 4.7K sessions): ### 15.1. Applied - Schema validation for DB operations: See databricks skill Section 8 ### 15.2. Not Applied - Completion status reporting: No consumer for this output - PreToolUse hook for SQL: Handled by skill guidance instead ## References - Hooks Reference: `https://code.claude.com/docs/en/hooks` - Permissions Reference: `https://code.claude.com/docs/en/permissions` - Skills Dynamic Context: `https://code.claude.com/docs/en/skills#inject-dynamic-context` - Vercel AGENTS.md Guide: `https://vercel.com/blog/agents-md` --- > Converted and distributed by [TomeVault](https://tomevault.io/claim/kumewata) — claim your Tome and manage your conversions.
