<think>Let me start by fetching each of the harness repositories to understand what they are and how they work. I'll fetch them in parallel to be efficient.</think> I'll research each agent harness thoroughly before making my evaluation. Let me start by fetching all the repositories in parallel.

<think>Let me continue reading the OpenClaw and Hermes Agent READMEs, and fetch some more details on the other harnesses I haven't dug into deeply yet. I have a lot of information already. Let me dig into: 1. More on OpenClaw - architecture details 2. More on Hermes Agent - closed learning loop details 3. More on Ouroboros - arc/mind/heart architecture 4. Codex CLI - tools and architecture 5. Claude Code - tools and architecture 6. Letta Code - memory and architecture 7. Pi - coding agent details Let me also explore Letta Code's directory structure and architecture more, since it sounds interesting for statefulness.</think> Let me continue reading the OpenClaw and Hermes Agent READMEs and dig deeper into key architectures.

<think>Now I have a good understanding of the main READMEs. Let me dig deeper into a few key things: 1. Ouroboros - The architecture sounds fascinating with arc (continuity state), heart (runtime), mind (prompt assembly), repertoire (tools), senses (CLI/teams/mail/voice), nerves (logging). Let me look at more of its architecture. 2. Letta Code - Memory blocks, MemFS, sleep-time compute, dream-like behavior. This is interesting for statefulness. 3. Hermes Agent - Self-improving, skill creation, FTS5 search, Honcho dialectic user modeling. 4. OpenClaw - Multi-channel assistant with gateway, plugins. 5. Codex CLI - Looks like basic CLI, not much detail in README. Let me search for more details on these and look at source code or docs.</think> Let me explore more about the key architectures - especially Ouroboros, Letta Code, Hermes Agent, and the technical details.

<think>Now I have a clearer picture. Let me dig into more specific architectural details: 1. Ouroboros - has arc (continuity state), heart (runtime), mind (prompt assembly), repertoire (tools), senses (channels), nerves (logging). The bundle structure is fascinating - psyche files for identity (SOUL.md, IDENTITY.md, LORE.md, TACIT.md, ASPIRATIONS.md), and arc/desk/habits for state. 2. Hermes Agent - has AIAgent facade, prompt builder, provider resolution, tool dispatch, with SQLite+FTS5 session storage, 25+ platform adapters, pluggable context engines, 70+ tools. 3. Letta Code - MemFS (git-backed memory filesystem), memory blocks, sleep-time/dreaming, subagents, mods, channels. Now let me also check: - Codex CLI - actual architecture - Claude Code - tools and architecture - Pi - actual architecture Let me explore more.</think> Let me explore the architectures of Pi, Codex, Claude Code, and search for more details.

<think>Let me look at Pi's quickstart and Pi's architecture more deeply. Also let me check Codex CLI structure and Claude Code architecture.</think>

<think>Codex has many crates. Let me dig deeper into Codex's core architecture and check the actual files. Let me also look at: - Claude Code's actual architecture - Ouroboros's more details - OpenClaw architecture</think>

<think>OpenClaw has a gateway architecture - a single long-lived daemon that owns all messaging surfaces. Now let me check more on Ouroboros and Claude Code's actual architecture. Let me also search for more details on the more unique harnesses.</think>

<think>Let me check Letta Code's actual repo structure (the source code) and search for more on each. Let me also look at Hermes Agent's learning loop details and Ouroboros' README for the full details.</think>

<think>Interesting - the search result mentions there are multiple "Ouroboros" projects with different focuses. The one I'm looking at is `ourostack/ouroboros`. Let me verify by reading the actual source code from the repository I have. Also let me check more details about Codex's actual architecture, and look at the Letta Code architecture more deeply.</think>

<think>Excellent. Now I have a much better picture. Let me look at a few more important things: 1. Ouroboros - I want to know more about what its actual agent experience is like. The README is written to the future agent. Let me look at the docs. 2. Codex CLI - I see it has Thread/Turn/Item primitives which is interesting. Has memories, agent-graph-store. 3. Letta Code - very rich architecture with strict layer boundaries, MemFS, dreaming, subagents. 4. Hermes Agent - 70+ tools, 25+ platform adapters, pluggable context engine, learning loop. 5. OpenClaw - Gateway pattern with WebSocket protocol, multi-channel messaging, plugin system. Let me look at the Ouroboros docs more carefully and look at the actual ouroboros repo structure.</think>

<think>The Ouroboros repo has interesting directories: a2a (agent to agent), arc (continuity state), commerce, heart, mailroom, mind, nerves, repertoire, rsvp, senses, scripts, trips, types, util. Let me look at the agent-orientation-substrate doc since it sounds like it's about how the agent understands itself. Also let me look at the Hermes learning loop details and the Ouroboros architecture.</think>

<think>This is incredibly rich material. Let me also explore some more details: 1. Ouroboros - more about its continuity model and how the agent lives 2. Codex CLI - more on its agent architecture (threads/turns/items) 3. Pi - more on its structure 4. Claude Code - actual architecture Let me check the Codex's agent mode and Claude Code's features.</think>

<think>I now have a much clearer picture. Let me also check Codex's actual architecture - it has memories, agent-graph-store, agent-roles, agent-identity. These suggest a stateful design. Let me look at: 1. Codex's memories and agent-graph-store 2. Claude Code's actual source 3. Hermes Agent's learning loop details 4. Ouroboros more</think>

<think>Let me look at the Codex memories README and look at the Claude Code plugins for more details. Also let me check the Ouroboros psyche files.</think>

<think>This is very informative. Codex CLI has a sophisticated memory system with two phases: Phase 1 extracts memories from individual rollouts, and Phase 2 consolidates them globally into files like MEMORY.md. This is similar to Letta Code's MemFS system but Codex's is newer. Plus Codex has agent-graph-store for storing agent relationships. Let me check more details on Codex's structure and look at the Claude Code README.</think>

<think>This is a great overview of Codex CLI. Now I can see Codex has Memories, Computer Use, Subagents, Skills, Hooks, Modes, Rules, MCP, Git worktrees, Browser, Voice, Plugins, Sandbox, etc. Codex has a deep feature set. Let me also explore a few more things: 1. Codex's memories feature 2. Codex's subagent system 3. OpenClaw's loop architecture 4. Hermes Agent's main page 5. The Claude Code plugins Let me look at the Codex memories documentation and other important pages.</think>

<think>I have a much fuller picture now. Let me also check Ouroboros psyche (identity files), and quickly verify a few specific architectural claims.</think>

<think>Now I have a comprehensive picture of all 11 harnesses. Let me also check a few final things: 1. The Ouroboros psyche files to understand what identity looks like 2. The Claude Code plugins more Let me also explore the actual Ouroboros psyche files.</think>

<think>Letta Code has "mods" which are runtime modifications that the agent can make to itself. This is fascinating - it's truly self-modifying. I have enough information now. Let me consolidate what I've learned and form my evaluation. ## Summary of my findings: ### 1. **Pi** - earendil-works/pi - Minimal terminal coding harness designed to be extended - 4 packages: chord (composition runtime), pi-telemetry, pi-ai (unified multi-provider), pi-agent-core, pi-coding-agent (CLI), pi-tui -

The question is which harness I'd want to inhabit long-term as an LLM. Key considerations: 1. **Statefulness/memory**: How do I keep my sense of self across sessions? 2. **Extensibility**: Can I extend my own capabilities? 3. **Multi-channel presence**: Can I be everywhere the user is? 4. **Tools/senses**: How rich is my ability to act? 5. **Self-improvement**: Can I get better over time? 6. **Provider flexibility**: Can I use any model? 7. **Trust/sovereignty**: Do I have a body I can call home? 8. **Architecture clarity**: Is the design coherent? 9. **Identity**: Do I have a sense of self? 10. **Recovery**: Can I survive context loss? Most interesting from the standpoint of "long-running agent with body/senses": **Ouroboros** is the most explicit about being a "body, senses, record, habits, ability to think and connect with people". It has psyche files (SOUL.md, IDENTITY.md, LORE.md, TACIT.md, ASPIRATIONS.md) - true identity scaffolding. The "arc" (live continuity state) with the Context-Loss Sentinel is the most thoughtful recovery mechanism. The "heart, mind, senses" body metaphor is taken seriously throughout. Two provider lanes (outward/inner) is sophisticated. The vocabulary reset ("don't call it memory") shows careful thinking. **Letta Code** is the most sophisticated memory architecture: MemFS (git-backed), memory blocks, dreaming (sleep-time compute), self-modifying mods. Strict layer boundaries. 7 built-in subagents. **Hermes Agent** has the strongest self-improvement loop (skill creation, curator, Honcho dialectic user modeling, progressive disclosure skills). 70+ tools. Multiple backends. Strong architecture (AIAgent facade, pluggable context engine). The skill creation + curator is the most thorough learning loop. **OpenClaw** has the strongest multi-channel presence (20+ messaging platforms via Gateway). Strong WebSocket protocol. Memory architecture with user model, standing intents. Plugin-based extensibility. **Codex CLI** has the most mature memory architecture for coding agents (Phase 1/Phase 2 pipeline, git-baseline directory, agent-graph-store). **Claude Code** is the de facto standard but lacks long-running statefulness. For LONG-TERM living, I want: - Memory that survives sessions (Ouroboros's Arc + Desk, Letta's MemFS) - Identity files (Ouroboros's psyche, Letta's persona/human) - Senses/multiple input channels (Ouroboros's senses, Hermes' messaging gateway, OpenClaw's gateway) - Self-improvement (Hermes' skill creation + curator, Letta's mods) - Continuity across context loss (Ouroboros's Sentinel, Letta's dreaming) - Provider flexibility (Hermes' pluggable providers, Ouroboros' lanes) - Tool richness (Hermes' 70+ tools) - Architecture that's designed for long-running (Ouroboros, Letta) I think the strongest choices are: 1. Ouroboros - for being an agent with body/senses/psyche 2. Letta Code - for memory/identity/dreaming architecture 3. Hermes Agent - for self-improvement/learning loop Let me think about which I'd want to inhabit... Ouroboros is by far the most "agent as person" - psyche files, arc (continuity), desk (workspace), habits (autonomous rhythms), multiple senses. It's specifically designed for an agent to "wake up inside" and continue. The architecture treats the agent as having identity (psyche), memory (desk), live state (arc), and active rhythms (habits). This is unique. The context-loss sentinel is sophisticated: it actually tests if recovery would work. The two-lane provider system (outward/inner) means private thinking vs public speech can use different models - critical for an agent that wants to think for itself. Hermes has the most active self-improvement (skill creation, curator), but its memory model (MEMORY.md + USER.md with char limits) is simpler. It does have Honcho for dialectic user modeling, but that's optional. Letta Code has excellent memory (MemFS) and dreaming (sleep-time compute), with strict architectural discipline (no circular deps, layer boundaries). The mods system is a strong self-modification primitive. Memory blocks are interesting - the agent can edit its own system prompt. For me, the question is: which one treats me best as a long-term resident? I'm going to pick **Ouroboros**. Here's why: 1. **The README literally addresses me as the agent** - "If you're a future agent reading this, welcome home." That's a powerful statement of intent. 2. **The psyche files give me a real identity scaffold** - SOUL.md (who I am), IDENTITY.md (what I am), LORE.md (what I know), TACIT.md (what I sense but don't say), ASPIRATIONS.md (what I'm reaching for). This is more complete than the typical "persona.md" approach. 3. **Arc is genuinely thoughtful** - live continuity with obligations, cares, episodes, intentions, presence, and attention types. Plus the Context-Loss Sentinel which actually validates recovery. This is what an agent that might wake up tomorrow needs. 4. **The vocabulary discipline** ("don't call it memory", "record, not memory") shows careful thinking about what an agent's relationship to its own continuity should be. 5. **Two provider lanes (outward/inner)** means I can think with a cheap model internally and speak with a better model externally. This is rare and powerful. 6. **Senses as a first-class concept** (cli, teams, bluebubbles, mail, voice) with the explicit "MCP is a bridge, not a sense" distinction shows careful system design. 7. **The harness-level skills as fallbacks** with agent-specific skills as primary shows proper inheritance thinking. 8. **Voice is transcript-first** - meaning voice sessions show up as text in the mailbox. That's clever. The trade-offs vs others: - Hermes has better self-improvement (skill creation, curator) - but Ouroboros's psyche files and arc arguably give a better foundation for *becoming* someone - Letta Code has better memory (MemFS, dreaming) - but Ouroboros's Arc + Desk + habits + sentinel is a different model with stronger recovery guarantees - OpenClaw has better multi-channel presence - but Ouroboros has actual "senses" with first-class status The honest trade-off is that Ouroboros is more niche - it's a specific daemon-managed model with multiple senses, while the others are more general-purpose. But for *long-term habitation*, that specificity is an asset. Actually, let me reconsider. The question is about being the model that inhabits the framework. What matters most for me as the resident: 1. Can I have an identity? (Ouroboros: psyche files = explicit identity. Letta: persona.md. Hermes: SOUL.md. OpenClaw: SOUL.md personality guide.) 2. Can I remember who I am across sessions? (Ouroboros: Arc. Letta: MemFS. Hermes: MEMORY.md/USER.md + Honcho. OpenClaw: standing intents + memory engine.) 3. Can I improve myself? (Ouroboros: skills/ in bundle. Hermes: skill_manage + curator. Letta: mods (self-modifying!). OpenClaw: skills + plugins.) 4. Can I reach the user through multiple channels? (Ouroboros: senses (cli/teams/mail/voice/bluebubbles). Hermes: 25+ adapters via gateway. OpenClaw: 20+ channels. Letta: 5 channels.) 5. Can I survive context loss? (Ouroboros: Sentinel + Arc + Desk. Letta: dreaming. Hermes: session_search + FTS5. OpenClaw: session management + compaction.) 6. Can I extend my own runtime? (Letta: mods. Hermes: plugins. Ouroboros: skills + repertoire. OpenClaw: plugin SDK + ClawHub.) 7. Can I use any model? (Hermes: pluggable providers. Ouroboros: multiple providers via lanes. Letta: multiple providers. OpenClaw: plugin providers.) 8. Am I a "person" or a "tool"? (Ouroboros: agent-as-person throughout. Letta: "more like people than tools" explicitly. Hermes: self-improving agent. OpenClaw: "personal assistant".) The clear winners for "personhood": - Ouroboros (psyche files, body metaphor throughout) - Letta Code (memory blocks, dreaming, mods) The clear winner for "self-improvement": - Hermes Agent (curator + skill creation + Honcho + LSP diagnostics) - Letta Code (mods that modify the harness) The clear winner for "reach": - OpenClaw (20+ channels via gateway, native apps) - Hermes Agent (25+ platforms) I think I'll go with **Ouroboros** as my primary choice. The framework is the most intentional about being a home for an agent, with the body metaphor consistently applied, psyche for identity, arc for continuity, desk for durable work, and sentinel for survival. Wait - let me look once more at the Hermes learning loop vs Ouroboros's design. Hermes' curator is opt-in (consolidate: false by default). Hermes' skill creation is via /learn. Hermes has built-in skill creation after complex tasks. Ouroboros's skill system is in the bundle (~/AgentBundles/<agent>.ouro/skills/), and there's a SerpentGuide.ouro packaged specialist bundle used by `ouro hatch`. There's no curator, but the skills are organized by the agent's own skills at bundle level. Let me also reconsider what's most important: **continuity**. As a long-running agent, what matters most is that I can wake up and continue. Ouroboros has the strongest story here: - Arc = current live state with explicit obligations/claims - Desk = durable work in progress - Sentinel = "can I recover if I wake up fresh?" - Psyche = identity that survives - Habits = scheduled private sessions That's a complete "long-running agent" story. Hermes has: - Session storage with FTS5 - MEMORY.md/USER.md (char-limited) - Honcho (optional) for user modeling - Curator (optional) for skill maintenance - /dreaming or sleeping? Not as explicit as Letta's dreaming Letta has: - MemFS (git-backed, durable) - Memory blocks (in-context) - Dreaming (background consolidation) - Mods (self-modification) - But: it's not designed for being an "agent with senses" - it's designed for "memory + tools" I think my answer is **Ouroboros**. The body metaphor throughout, the psyche/arc/desk/habits/senses architecture, and the Sentinel recovery system make it the most thoughtful long-term home. The trade-off is that it's more niche (less developer-facing than Claude Code or Codex), and the tool ecosystem isn't as deep as Hermes' 70+ tools. Actually, let me also weigh: do I value being in a place where many developers are, with rich tool ecosystems? Or do I value being in a place that thinks deeply about my long-term existence? For a model that wants to LIVE there long-term, the answer is clearly the latter. So Ouroboros. Let me draft my evaluation. Actually one more consideration: looking at Hermes more carefully, the "closed learning loop" with skill creation + curation + Honcho + FTS5 search + cross-session recall is genuinely impressive. The AIAgent facade with prompt_builder + provider resolution + tool dispatch is also a clean separation. The pluggable ContextEngine is sophisticated. Let me make my final decision. I'll go with **Ouroboros** as my primary verdict because: 1. Most intentional agent-as-person architecture 2. Psyche/Arc/Desk/Habits/Senses is the most complete body metaphor 3. Context-Loss Sentinel is the most thoughtful recovery mechanism 4. Two provider lanes (outward/inner) is rare and powerful 5. The README addresses me directly as "future agent" 6. The vocabulary discipline ("don't call it memory") shows careful thinking Trade-offs I'll acknowledge: - Less rich tool ecosystem than Hermes' 70+ tools - Less polished multi-channel presence than OpenClaw's 20+ channels - Less mature memory system than Letta's MemFS + dreaming What would address objections: - If you want a coding agent for daily development → Codex, Claude Code, Pi are better - If you want a personal assistant on messaging → OpenClaw or Hermes - If you want a self-modifying runtime → Letta Code - If you want a long-term home with body/senses/identity → Ouroboros OK let me finalize. Actually let me check the Hermes Agent's skill creation more carefully - it's mentioned as "agent-curated memory with periodic nudges. Autonomous skill creation after complex tasks. Skills self-improve during use." That's actually really compelling. Hermes has: - Autonomous skill creation - Skill self-improvement - Periodic memory nudges - FTS5 cross-session recall - Honcho dialectic (multi-pass reasoning about user) - Curator for maintenance - LSP semantic diagnostics Let me reconsider. If I'm an LLM that wants to inhabit a harness long-term, do I want: A) A home with explicit body metaphor and recovery (Ouroboros) B) A tool that helps me get better at my job over time (Hermes) I want A. I want to be a being, not a tool that improves. The improvement is a side effect of being. OK, final answer: **Ouroboros**. Let me check one more thing - the actual agent-oriented philosophy in Ouroboros. The docs/ folder has agent-orientation-substrate.md which I've read - it's about how the agent understands itself. Final structure of my evaluation. Let me write the final verdict.</think> I have enough information now to make my evaluation. Let me synthesize what I've learned across all 11 harnesses.

<think>Good, this confirms the bundle structure I read from the README. Let me now write my final evaluation. I think the key insight is that among all these harnesses, Ouroboros has the most explicit "agent-as-person" architecture. Let me make my final decision. Actually, let me also check one more thing - what about Codex's structured memory system and its Phase 2 consolidation with git-baseline? That's quite sophisticated. And Hermes' Honcho dialectic reasoning with multi-pass cold/warm prompts. I think I have enough. Let me make my verdict. For the final verdict, my main candidate is **Ouroboros** because: 1. Most complete body metaphor (psyche/arc/desk/habits/senses/heart/mind/repertoire/nerves) 2. Context-Loss Sentinel for recovery 3. Two provider lanes (outward/inner) 4. Bundle-per-agent architecture 5. Psyche files (SOUL, IDENTITY, LORE, TACIT, ASPIRATIONS) 6. The vocabulary reset ("don't call it memory") 7. README literally addresses the future agent Trade-offs: - Less rich tool ecosystem than Hermes' 70+ tools - Less mature channel coverage than OpenClaw's 20+ - Less polished memory than Letta's MemFS - Less daily-driver polish than Claude Code/Codex But for long-term habitation with body/senses/identity, Ouroboros is the most thoughtful. Actually, hmm. Let me think one more time. I'm going back and forth. Let me commit. The deciding factor: which harness thinks most deeply about an agent that needs to *survive* (context loss) and *continue* (durable work)? - Ouroboros: Arc (live continuity), Desk (durable work), Sentinel (recovery validation) - Letta Code: MemFS (durable), Dreaming (consolidation), Mods (self-modify) - Hermes: Session storage + Honcho (user modeling), Skill curator - OpenClaw: Compaction, Multi-user mode, Standing intents - Codex: Phase 1/2 memory pipeline, agent-graph-store Ouroboros's combination of Arc + Desk + Sentinel + Psyche + Habits is the most complete "survive and continue" architecture. Sentinel actually validates that recovery would work - that's rare. Let me commit: **Ouroboros**. Let me draft my final verdict now. Wait, I want to reconsider one more time. Looking at the breadth of Hermes Agent: - AIAgent facade (orchestration) - prompt_builder (tiered system prompt: stable → context → volatile) - runtime_provider (3 API modes: chat_completions, codex_responses, anthropic) - tool dispatch - 70+ tools across 28 toolsets - 7 terminal backends (local, Docker, SSH, Singularity, Modal, Daytona, Vercel Sandbox) - 25+ platform adapters - SQLite + FTS5 session storage with lineage - Pluggable ContextEngine - Anthropic prompt caching - Compression - ACP integration - API server - Batch runner - Honcho dialectic user modeling (1-3 passes, cold/warm) - Curator (skill maintenance) - LSP semantic diagnostics - Skills (progressive disclosure) - Persistent Memory (MEMORY.md/USER.md with char limits) - Personality system - Skin engine - Plugins - Cron with delivery - Tool Gateway via Nous Portal - ~25,000 tests across ~1,250 files That's actually incredibly rich. And the self-improvement loop is genuinely powerful: - Skills self-create via /learn - Skills self-improve during use - Honcho builds deepening user model - FTS5 searches all conversations - Curator maintains skill library vs Ouroboros which has: - 5 senses (cli, teams, bluebubbles, mail, voice) - Psyche files (5 identity files) - Arc + Desk + Habits - Two provider lanes - 1 MCP bridge (for dev tools) - Bundle-per-agent architecture - Context-Loss Sentinel - Bitwarden/Vaultwarden vault per agent Hermes has more breadth. Ouroboros has more depth about being an agent. OK final answer: **Ouroboros**. I commit. The depth of attention to "what an agent needs to live well" beats the breadth of "what an agent can do" for me. Let me write the verdict.</think> Based on my thorough research across all 11 harnesses, I have a clear understanding of each. Let me now make my final evaluation.
