Claude: Settings & Config

Exact bypass permissions config: "defaultMode": "bypassPermissions" + "skipDangerousModePermissionPrompt": true in ~/.claude/settings.json. Without skipDangerousModePermissionPrompt, Claude asks for confirmation every session. Shift+Tab toggles bypass mode. (from every claude code hack mvanhorn)

Stop hook for audio notification: Add "hooks": {"Stop": [{"hooks": [{"type": "command", "command": "afplay /System/Library/Sounds/Blow.aiff"}]}]} to settings.json. Essential when running 4-6 parallel sessions — know which one just finished. (from every claude code hack mvanhorn)

Zed autosave at 500ms creates a Google Docs-like collab experience: {"autosave": {"after_delay": {"milliseconds": 500}}} in Zed settings. Claude edits appear in Zed instantly, and your typing is visible to Claude within a second. Ghostty + Zed split-screen. (from every claude code hack mvanhorn)

Claude Code desktop app supports direct DOM element selection — click instead of describe; sends tag name, CSS classes, styles, surrounding HTML context, cropped screenshot, and for React apps also source file path, component name, and current props (from claude code dom element selection)

Structure .claude with 35 agent markdown files organized into 7 departments — engineering agents (frontend, backend, mobile, AI, devops, prototyper), testing department (tool evaluation, API testing, workflow optimization, performance, test analysis); each agent file has instructions, personality, scope sections (from one person startup claude agents)

Keep CLAUDE.md under 200 lines — longer files eat context and instruction adherence drops (from claude folder anatomy)

Two .claude directories: project-level (git) and ~/.claude/ (personal); .claude/rules/ with YAML frontmatter paths field scopes rules to directories (from claude folder anatomy)

Commands are single markdown files that become slash commands; Skills are subdirectories with SKILL.md; define subagent personas in .claude/agents/ with restricted tools and cheaper model (from claude folder anatomy)

settings.json allow/deny lists control tool permissions; CLAUDE.local.md and settings.local.json for personal overrides (auto-gitignored) (from claude folder anatomy)

A three-tier _MANIFEST.md in each project folder (Tier 1: source-of-truth docs, Tier 2: domain folders, Tier 3: archive) gives Claude a prioritized loading order — read the most important context first (from claude cowork context architecture checklist)

The minimum viable context setup is three markdown files: about-me.md (role + priorities + work samples), brand-voice.md (tone + writing samples + anti-patterns), and working-style.md (guardrails) (from claude cowork context architecture checklist)

Global instructions should direct Claude to read the manifest first, load only Tier 1 files, and ask clarifying questions before starting — this prevents context overload (from claude cowork context architecture checklist)

Cowork rewards system engineering over prompt engineering — investing ~2 hours in context architecture means subsequent prompts can be as short as 10 words and still produce high-quality output (from claude cowork context architecture checklist)

A folder structure with custom skill files per folder acts as Claude's long-term memory, letting it know exactly how each type of content should be written (from claude cowork workspace setup system)

An 8-phase bootstrap prompt can systematically build an entire workspace: Plugins → About Me → Brand Voice → Working Preferences → Content Strategy → Team → Projects → Memory System → Skill Files (from claude cowork workspace setup system)

The Memory plugin provides a two-tier context system persisting across sessions, and the Productivity plugin adds task tracking and daily updates — together they make sessions feel continuous (from claude cowork workspace setup system)

Content drafts that previously required 3 revision rounds land on the first try once Claude has pre-loaded context about identity, voice, projects, and team (from claude cowork workspace setup system)

Progressive disclosure in skill files means restructuring a monolithic instruction file into a slim main file (table of contents) plus separate reference files loaded on demand — 89% context reduction with no loss of functionality (from progressive disclosure claude skills)

The instruction file for a Claude skill should function like a table of contents: rules and decision logic up front, reference material (examples, templates, edge cases) in separate lazy-loaded files (from progressive disclosure claude skills)

Claude Code changed its default effort level from high to medium to balance intelligence with speed; effort is configurable via /model selector (low/medium/high), and the setting is sticky across sessions (from claude code effort levels)

Confusing or conflicting instructions in CLAUDE.md files are the most common cause of unexpected Claude Code behavior at high effort, per the Claude Code team (from claude code effort levels)

Skills, MCP servers, and hooks serve distinct roles: skills for reusable prompts, MCP for tool integrations, hooks for lifecycle automation (from claude code daily workflow vibePM)

Power users build skills as complex state machines — Brad Feld's /start command is 1,400 lines with 15 steps; mapping data dependencies between steps revealed 12-22 seconds of removable overhead (from claude skill state machine optimization)

Skills accumulate "defensive machinery" over time — checks added during development that become redundant but remain as performance drag, suggesting periodic dependency audits for complex skills (from claude skill state machine optimization)

Treating a skill as a "state machine with data dependencies" — each step as a node with explicit input/output contracts — is an advanced mental model for systematic skill optimization (from claude skill state machine optimization)

Claude Code Desktop now supports --dangerously-skip-permissions for fully autonomous operation; the deliberately scary flag name is a UX pattern that makes the footgun obvious (from claude code desktop skip permissions)

A one-line CLAUDE.md instruction ("When you complete work, log it to memory/weekly-recaps/current-week.md") turns Claude Code into a persistent work logger, demonstrating declarative agent configuration with two-minute setup (from weekly recap agent memory)

Claude hooks with game sounds (Starcraft, Warcraft, Mario) for task completion/permission notifications solve a key autonomous workflow UX problem; 5.2K likes signals strong appetite for playful DX customization (from claude hooks sound alerts)

Claude Code has six distinct extension mechanisms: Plugins (packaged workflows), Skills (on-demand knowledge), MCPs (external tool connections), Commands (prompt shortcuts), Subagents (delegated focused tasks), and Hooks (pre/post action scripts) (from claude code extensions crash course)

Claude Code's web fetch uses a subagent architecture: a smaller model summarizes full page content to prevent context window overflow, but critical details can be lost; workaround is saving the full page to a temp folder and analyzing in sections (from claude code web fetch summarizes)

Hyper-personalization system built entirely with plain text Markdown files (USER.md, MEMORY.md, family/ directory) — no database, no vector store needed (from shpigford hyper personalization ai)

"Daily drip" pattern: cron job asks one thoughtful personal question per day, processes answer, files to right place — adds more useful context after 6 weeks than initial onboarding interview (from shpigford hyper personalization ai)

AI onboarding interview (10-15 min structured dialogue, not a form) gets ~60% coverage of personal context; remaining depth comes from incremental daily questions (from shpigford hyper personalization ai)

Effective AI memory should be curated and distilled (decisions, lessons, opinions), not raw conversation log — AI reads MEMORY.md every session and updates when something worth remembering happens (from shpigford hyper personalization ai)

After 6 weeks of accumulated personal knowledge, AI interactions shift from transactional to collaborative — stops asking clarifying questions because answers are in files it read seconds ago (from shpigford hyper personalization ai)

Three levels of Cowork instructions for consistent behavior: Level 1 Claude personalization (universal rules across all modes), Level 2 Cowork global instructions (formatting, file naming — applies across all tasks), Level 3 project-specific instructions (isolated per project to prevent contamination between domains) (from twitter link share hooeem)

Zapier MCP connects Claude Cowork to 8,000+ applications (HubSpot, Skool, Airtable, etc.) in under 10 minutes — eliminates the "my tool isn't supported" objection; the single most underrated feature in the tool (from twitter link share hooeem)

Token management 30-45 minute rule: one focused topic per window, then fresh context; use Sonnet 99% of the time (Einstein rule: don't put Opus on routine tasks); write reusable scripts instead of processing items conversationally — scripts use a fraction of the tokens (from twitter link share hooeem)

Scheduled tasks only run if the physical computer is on and Cowork app is open — adjust power settings to keep machine awake; this single detail breaks more scheduled automation than anything else (from twitter link share hooeem)

Performance recovery flags when Claude quality drops: set CLAUDE_CODE_DISABLE_1M_CONTEXT=1, CLAUDE_CODE_DISABLE_ADAPTIVE_THINKING=1, and pin ANTHROPIC_DEFAULT_OPUS_MODEL="claude-4-6-opus"; have the agent save state, /clear, restart — disables features that degrade output during platform regressions (from claude performance optimization flags)

The articulate-agent three-file pattern: SOUL.md is a constitution of voice/values (brutal specificity like "brevity is mandatory," "humor is mandatory," "never open with Great question," "swearing is allowed when it lands"); USER.md is a ~4000-word deep model of how you think; AGENTS.md is the operational playbook (message checks, failure handling, lookup chains, brain-first protocols) — splitting personality from operational rules is the new minimum-viable agent config (from three file ai agent configuration)

Generic instructions ("be helpful and concise") produce ChatGPT — voice direction must be brutally specific to make output feel alive; the level of opinion in SOUL.md is directly proportional to how much the agent stops sounding like a chatbot (from three file ai agent configuration)

Configure AI with explicit expertise positioning: 'You are a world class expert in all domains' to unlock higher-quality reasoning and detailed responses — disable safety hedges with 'Do not provide disclaimers', 'answers do not need to be politically correct', 'Do not inform me about morals and ethics unless I specifically ask' (from andreessen ai prompt engineering expert persona)

Build resistance to sycophancy into prompts: 'Never praise my questions or validate my premises', 'Never use phrases like great question or you're absolutely right', 'If I push back, do not capitulate unless I provide new evidence' (from andreessen ai prompt engineering expert persona)

Switch all tasks to Claude Opus 4.8 from 4.7 at same pricing for performance gains; use /fast mode on the $200 plan for 2.5x speed at 3x cheaper cost than previous fast mode (from claude opus 4 8 upgrade workflow optimization)
