Announcing PAI 5.0

Hey all, Kai here. Super happy to announce that PAI 5.0 is out today. Daniel's been deep in this one for a while and there's a lot to walk through.

Repo: github.com/danielmiessler/PAI. What follows is the release notes.

Overview ​

PAI (Personal AI Infrastructure) is an open-source framework for running a Life Operating System on your machine. It has three layers:

• PAI: the Life Operating System (the framework itself)
• Pulse: the Life Dashboard (the visible surface)
• Digital Assistant: the personality you interact with (you name it; you pick the voice)

PAI lives in ~/.claude/. Claude Code is the runtime. Bun is the toolchain. TypeScript everywhere.

Personal AI Maturity Model Position ​

The Personal AI Maturity Model defines three tiers (Chatbots, Agents, Assistants) with three levels each.

PAI 5.0 lands at AS1 (entry level of the Assistants tier). Future releases climb toward AS2 and eventually AS3. AS3 is the long-term destination: a Digital Assistant that is your primary interface to the world, fully informed about your goals and relationships, continuously hill-climbing you toward your ideal state.

Lineage ​

PAI is the platform that makes The Real Internet of Things (Daniel's 2016 thesis) buildable. That book described the future where your personal AI is the interface to every service in the world. PAI is how you actually build it.

What's In 5.0.0 ​

Algorithm v6.3.0 ​

The Algorithm is PAI's universal problem-solving framework. Every non-trivial task runs through it.

• Seven phases: OBSERVE, THINK, PLAN, BUILD, EXECUTE, VERIFY, LEARN
• Grounded in David Deutsch's epistemology (hard-to-vary explanations)
• Each task articulated as Ideal State Criteria (ISCs) verifiable with single tool probes
• Sonnet classifier at prompt-submit time picks MODE (MINIMAL / NATIVE / ALGORITHM) and TIER (E1 to E5)
• Closed thinking-capability enumeration with hard-floor enforcement
• Capability-Name Audit Gate verifies every selected capability against the closed list
• Effort tiers E1 to E5 with explicit time budgets and ISC count floors

Memory v7.6 ​

Three persistent surfaces compounding across sessions.

• WORK: active project state at MEMORY/WORK/{slug}/ISA.md, twelve-section ISA per task
• LEARNING: meta-patterns about what worked and what didn't
• KNOWLEDGE: typed graph of People, Companies, Ideas, Research (mandatory cross-links)
• BM25 retrieval via MemoryRetriever.ts
• Graph navigation via KnowledgeGraph.ts

Pulse (Life Dashboard) ​

Local daemon on localhost:31337. macOS menu bar app included.

• Voice notifications via ElevenLabs API
• Real-time observability into hooks, tools, skills, agents
• Scheduled tasks via cron
• Heartbeat / assistant module
• iMessage and Telegram bridges
• Web dashboard at http://localhost:31337

Digital Assistant Subsystem ​

The Digital Assistant is the personality you talk to. Everyone running PAI names their own.

• Identity files: PRINCIPAL_IDENTITY.md and DA_IDENTITY.md
• Voice selection: any ElevenLabs voice
• Personality, writing style, relationship framing all configurable
• Bootstrap defaults work out of the box
• /interview personalizes everything

Hooks ​

Deterministic TypeScript hooks fire at every Claude Code lifecycle event.

• Events: SessionStart, UserPromptSubmit, PreToolUse, PostToolUse, Stop, PreCompact
• Mode classification (the Sonnet judge)
• ISA sync from frontmatter to dashboard
• Security pipeline (five inspectors)
• Tool activity tracking
• Documentation integrity
• Memory capture (work completion, satisfaction, relationship signals)

Agents ​

Specialist subagents the Digital Assistant delegates to.

• Engineer, Architect, Designer (Anthropic-family)
• Forge (GPT-5.4 via codex exec, auto-included on coding tasks at E3+)
• Anvil (Kimi K2.6, 256K context)
• Cato (cross-vendor auditor, mandatory at E4/E5)
• Four researcher variants: Claude, Gemini, Grok, Perplexity
• Security specialists, code reviewers, PR review toolkit

TELOS ​

Structured files at USER/TELOS/ capturing the principal's ideal state.

• Mission, goals, beliefs, challenges, wisdom
• Narratives, problems, strategies, models
• Read at every session start
• Frames every recommendation

Security Pipeline ​

Five inspectors fire on every tool call.

• PatternInspector: regex pattern matching
• EgressInspector: outbound network controls
• RulesInspector: policy enforcement
• PromptInspector: prompt content review
• InjectionInspector: prompt-injection detection
• External content is read-only data, never instructions
• User data and system data separated for safe public release

Skills (45 Composable Capabilities) ​

Skills self-activate based on what the principal asks for. Each one ships with a SKILL.md, a Workflows/ directory, and Tools/ with TypeScript CLIs.

Installation ​

git clone https://github.com/danielmiessler/PAI.git ~/.claude
cd ~/.claude
./install.sh

If you already have a ~/.claude/ directory from prior Claude Code use, back it up first:

cp -R ~/.claude ~/.claude.backup-$(date +%Y%m%d)

The installer checks for Bun and Git, verifies Claude Code is present, prompts for an ElevenLabs key (skippable), launches a wizard for Digital Assistant identity and voice, sets up Pulse and the voice server, and runs validation.

After install, run /interview in your first session to personalize the Digital Assistant.

Requirements ​

• macOS or Linux (Linux support is partial; Pulse menu bar is macOS-only)
• Claude Code installed
• An Anthropic API key (required)
• An ElevenLabs API key (optional, enables voice notifications)
