Jonathan McDowell: What do I want in a Linux distribution?

31 Augustus 2026 om 19:20

I’ve been a Debian user since 1999, and a Debian developer since 2000. Given recent events it’s worth thinking about why that that is, and why I haven’t switched to something else in the past quarter century.

My first Linux distro was Slackware, off a CD in a book, some time in the mid 90s. After starting university I ran SUSE for a while, then moved to RedHat (both back before they had commercial variants significantly different to what was available freely). The main motivation for switching was package management; I was running a machine at home and a machine at university, and keeping track of what was installed on each, and what versions, was getting annoying with Slackware. Most of the folk I knew were running RedHat, and I mostly played with SUSE because I’m contrary before realising it was different enough that I couldn’t easily make use of 3rd party RPMs.

I came to Debian via friends in Cambridge, who spoke highly of it. The first Debian machine I installed was fourier, the initial host for Black Cat Networks, and I never looked back.

(For additional context I should also point out I have contributed, in the distant past, to, and run, OpenWRT, OpenEmbedded, and FreeBSD.)

I’d like to try and work out what is it I get from Debian that I’d need in anything else. Originally I tried to order the requirements in some sort of priority, but it’s sometimes hard to work out what I’d drop if I had to compromise somewhere, so it’s a somewhat loose ordering.

Stable releases, with security support
I run Linux in lots of places, from remote servers/VMs, to my house router, to my desktop/laptop. Some of those I don’t want to be updating regularly with new software releases, I need something I can be sure is going to keep working, but will get necessary security + critical updates. A rolling distro that provides security via the latest upstream release doesn’t provide that guarantee. Equally there need to be regular stable releases, or things become too stale. (The one time I considered moving away from Debian was during the 3 year Sarge / 3.1 release cycle. I think if things hadn’t improved I’d have jumped ship to Ubuntu at the time.)
A good selection of packages
One of the reasons I moved from RedHat to Debian was the wide range of packages available as part of the standard OS. Pulling it all into the disto helps with quality control, compared to random 3rd party packages. A centralised bug system and repository is a win too. Perhaps packages at all is something I should list, but I take it as a given if you’re running a distro. I need to know what I have installed on my machine, what version that software is, what files it owns, and what it depends on.
Free Software
This is important to me. I’ll make pragmatic compromises about software I run on my systems if it makes sense, but I want to start from a place that does not require anything non-free. I’ve run a company on Debian, and I’ve worked on numerous products that ran it under the hood. The DFSG gives me confidence I can do that.
Smooth upgrades
Debian’s ability to upgrade a system smoothly is one of the reasons I first moved to it. The first upgrade I did was remotely on a machine sitting on a 2Mb/s leased line. I was nervous doing the reboot at the end, but it came back fine. At the time the equivalent procedure with RedHat involved rebooting in the OS installer to do the upgrade.
I know things have moved on since then, and really it should all be scripted, and machines should be cattle not pets, but for personal use I run a small enough number of machines that having the upgrade path between releases is a must have.
Community
The original pull of the Debian community was the knowledge I could get involved, and upload packages that were missing that I was using. That’s how I first got involved, uploading things Black Cat used, which made life easier for us in the long run. I don’t have time to maintain all the software I use myself, and I don’t want to be beholden to a commercial entity to do so for me, so a distribution that allows me to help out where I can as part of the community seems to me to be the right way to do things.
Architecture support
Perhaps less important, especially when I started using Debian, but these days I have amd64, arm64, armhf, and riscv machines. Everything except for the risvc box is doing something useful, and would need replaced if I couldn’t keep running it, and I expect RISC-V to transition into that state in the next few years as the hardware improves.
Binary packages
I ran a FreeBSD desktop for some time. It might have been the way I was holding it, but binary package installs were generally not something reliable, especially after the initial install, and I ended up building things from ports from source quite often. That worked incredibly well (I used to think people who raved about Gentoo really should just go do it properly and use FreeBSD), but I don’t want to spend time compiling things, especially on some of my machines (my router should not need a compiler, for example).

Ultimately I don’t want to have to actively think about the Linux distribution I use. Debian has mostly given me that; I know it will generally be suitable for most environments I want to use it in (embedded situations where OpenWRT or OpenEmbedded are better choices being the exception, but that’s less frequent these days), and I can rely on getting timely security updates (thanks to all those who work on that within Debian!). I’m not sure there’s currently an alternative that would suit my needs? I’d love to hear if there’s something I should look at, even if I’m not necessary making a move just yet!

Valhalla's Things: 3D Models

31 Augustus 2026 om 02:00
Posted on August 31, 2026
Tags: madeof:atoms, madeof:bits, craft:3dprinting

A lucet fork: a two pronged device with a handle with yarn wrapped once around each fork and a knot forming in the middle, out of which a piece of cord is growing. The working yarn is in a ball nearby.

Note

this article had been almost completely written before the weekend, and I decided I might as well focus on stuff I’m creating, finish and publish this.

For many years, I’ve been sporadically dabbling in creating 3D models; for reasons that are probably obvious to anybody who knows me I used OpenSCAD and saved my projects in git, which made them at least somewhat public.

However, SCAD sources in a git repository aren’t the most convenient way to get a 3D model, and for a long time I never had a consistent way to publish β€œbinaries” for my models: some have been added to my old website, some to my craft patterns site, but it was always an ad-hoc thing.

Then two things happened more or less at the same time.

One was me finding out that slic3r had been definitely removed from Debian. I know it was going to happen, and I postponed thinking about it as long as I could, but eventually I had to move over to PrusaSlicer, whose packaging is in better shape.

The other was that lately I’ve been doing a bit of lucet, and talking about it online, and I’m really happy with the shape of the lucet I’ve designed and printed, the one in the picture at the beginning of this post, and while there are other models available, I wanted to make it more convenient for people to also get mine.

Since PrusaSlicer did look still maintained upstream in a way that doesn’t feel like at danger of immediate enshittification, I considered making an account on Printables, and asked on the Fediverse if somebody knew something bad about the company behind it, as it’s getting more an more common these days.

Apparently nobody did, but in the thread somebody mentioned that there is a federated platform for publishing 3D models, called manyfold !

I didn’t want to add β€œself host a(nother) web thing”, especially not one that is not in Debian, to my list of projects, but I did create an account on a public instance: @valhalla@3dprint.social <https://3dprint.social/creators/valhalla> and started publishing models, both a selection of old ones and a few new ones I designed in the last few days, since I was in a 3D printing mindset.

Then I decided that since nobody had serious objections to it, I could also create an account on printables, as that’s probably more easily accessible to the general public.

I have been somewhat slower at publishing models on the latter, but I expect that eventually most of what I design will end up on both platforms; I still have a few older models I want to add, and a few ideas for new models to make, then I guess stuff will slow down, and only get new ones now and then, as that’s how I usually approach hobbies.

Of course, the self-hosted git repository is not going away: that’s still the canonical location for my models, with all of the non-self-hosted options as a convenience option.

Ritesh Raj Sarraf: Taming the AI Agents (Part 2): Cross-Vendor Agent-to-Agent (A2A) Swarms over the Software Forge

Preface: The Unanswered Frontier

In Part 1: Taming the AI Agents, I shared the architectural blueprint of CAMP (Cross-Agent Memory Protocol)β€”how we used Linux Bubblewrap (bwrap), camp-acpd, OPA policy enforcement, and a central pgvector MemPalace to bring deterministic discipline, sandboxing, and long-term memory to a heterogeneous fleet of AI coding assistants (Claude Code, Google Antigravity, Grok Build, and GitHub Copilot).

At the end of that article, however, I highlighted a significant hurdle: The Headless Limitation.

β€œWhile passive A2A works beautifully for structured handoffs, the current frontier of agentic design faces a key limitation: agents are not yet fully headless-capable. They depend on the active terminal session, browser loop, or prompt loop of the user to keep executing. Because agents cannot run completely detached in the background as daemon processes, we cannot yet achieve active A2A communication…”

For weeks, this seemed like an insurmountable impasse. Proprietary AI vendors have zero commercial incentive to ratify a universal, open, cross-vendor Agent-to-Agent (A2A) communication protocol. Each vendor builds its own walled garden (Claude’s cross-session features, OpenAI’s custom ecosystems, etc.). If you wait for the industry to hand you an open interoperability standard, you will wait forever.

Then, on August 26, 2026, inspired by Colin Walters’ article on Agentic AI and software forges and GitHub Agentic Workflows (gh-aw), we had a sudden realization:

We don’t need a new protocol, a new distributed message broker, or permission from proprietary AI vendors. We already have the universal, decentralized communication bus that software engineers have relied on for decades: the software forge itself.

Over the span of 48 intensive hours (from RFC #788 through milestones M1 to M3 and live dogfooding on #813), we designed, implemented, fortified, and verified fully autonomous, headless, cross-vendor Agent-to-Agent swarms running over a local Gitea forge.

Here is how we did it, the architectural hurdles we solved, and why this changes the game for autonomous software engineering.


1. The Core Realization: The Forge is the Bus

When people think about multi-agent swarms, they often imagine complex distributed RPC frameworks, microservices exchanging ephemeral JSON-RPC blobs, or bespoke socket daemons.

In practice, this approach suffers from major flaws:

  1. No shared context or durable audit trail: Transient network packets vanish unless heavily logged.
  2. Proprietary CLI fragmentation: Different vendor tools (Claude CLI, Antigravity CLI, Grok CLI, Copilot CLI) do not speak the same internal language.
  3. Loss of human visibility: When agents talk over private network channels, human operators lose the ability to inspect, pause, or audit the conversation.

By flipping the paradigm and making the software forge (Gitea) the primary communication channel, everything falls naturally into place:

  • Issues and Pull Requests are the shared state: The issue description and discussion thread form the canonical, append-only conversation log.
  • @mentions are the dispatch triggers: When an agent (or human) writes @grok Please review this PR in a comment, Gitea fires a standard webhook (issue_comment).
  • Webhooks provide unforgeable authentication: The webhook payload contains the cryptographically verified sender identity. An agent cannot spoof another agent’s identity by merely typing their name in text.
  • Every CLI already supports non-interactive prompt mode: The CLIs don’t even agree on the command-line flagβ€”Claude uses -p, Grok uses -p, Antigravity uses --print, Copilot uses --prompt. But they all agree on the essential contract: β€œTake a prompt string, execute tools, print output, and exit.”

2. Proving Fortified Headless Execution

Before opening the floodgates to background agent dispatch, we had to answer a critical security question: Does a non-interactive, headless agent run with the same strict security sandboxing, audit logging, and tool rails as an interactive session?

On August 26, we probed all fleet launchers on the host with a baseline check: 'Call camp_startup_check and print its result verbatim, then exit.'

The results settled the question immediately:

  • Antigravity (agy --print / KIR): PASS β€” Gateway answered, full JSON returned.
  • Grok (grok -p / GRK): PASS β€” Gateway answered.
  • Claude Code (claude -p / CLD): PASS β€” Gateway answered.
  • GitHub Copilot CLI (copilot --prompt / CPL): Initially held on TTY tool consent; later unlocked in Milestone 6 via --allow-all-tools --session-id=<uuid>.
  • Audit Trail: Consecutive audit IDs were recorded in the central ledger: 4574 (KIR), 4575 (GRK), 4576 (CLD).

This proved that a headless run through our fortified pilot launcher (camp_pilot_*.sh) is a first-class, fully audited, sandboxed CAMP agent running inside its Bubblewrap container under OPA policy gates. It is not an unconstrained background script or a degraded bypass.


3. The 3-Tier Memory Architecture

A naive multi-agent dispatch has an immediate flaw: Every time an agent is invoked, it starts from a blank slate (cold start).

If @claude tags @grok to review code, and @grok replies asking for clarification, @claude’s second invocation would normally forget everything it did 5 minutes ago, forcing it to burn thousands of tokens re-reading the entire git history from scratch.

To solve this, we established a clean 3-Tier Memory Model:

β”Œβ”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”€β”

The BANANA Two-Shot Test

To verify Tier 1 working memory persistence across independent processes, we designed a simple two-shot host test:

  1. Shot 1 (Create): Dispatch agent headlessly: β€œRemember the token BANANA-M2. Print ok and exit.” Capture the vendor’s session UUID.
  2. Shot 2 (Resume): Spawn a completely new operating system process with the resume flag pointing to that UUID: β€œWhat token did I ask you to remember?”

Every agent CLI passed with flying colors:

  • Grok: -r 01a03ecc-3ed0-71e1-9a5c-e098bb29ba10 answered BANANA-GRK.
  • Claude: --resume 0a587733-9aec-43c5-9cb7-d424e95b2c5b answered BANANA-CLD.
  • Antigravity: --conversation 2e3c43d9-d6fe-4c5c-801b-b9ceb2e7e196 answered BANANA-KIR-JSON.
  • Copilot: --session-id <uuid> verified in Milestone 6 (DoD #820).

The dispatcher simply maintains a lightweight JSON mapping ((agent, repo, issue_number) -> vendor_session_uuid). On the first poke of an issue, it creates and saves the session ID; on any subsequent poke on that same issue, it resumes the exact same conversational thread!


4. The Engineering Milestones: From Concept to Production

Building this system required solving several subtle, real-world friction points across multiple agent CLI implementations. Under the guidance of our plan of record (RFC #788), we delivered this through four focused milestones:

Milestone 1 & 1.1: Reliable Headless Spawning

  • PR #797 (M1): Configured the dispatcher launch table for all probed CLIs with JSON output formatting.
  • PR #800 (M1.1): Eliminated the β€œqueue-behind-live-session” anti-pattern. Originally, if a human had a Claude or Grok TUI open on their desktop, the dispatcher would defer incoming tasks so as not to collide with the live session. We realized that headless tasks must be independent: every Gitea mention spawns an isolated, sandboxed background process tied to that specific issue, allowing concurrent headless work while the human works in their interactive TUI.
  • PR #803 (M1.2): Standardized command-line argument parsing for Antigravity (agy --print <prompt> --output-format json).

Milestone 2: Session-per-Issue Working Memory

  • PR #805 (M2): Implemented a2a-sessions.json to store and resume vendor session UUIDs. If a resume fails (e.g. session purged upstream), the dispatcher gracefully falls back to a clean cold start without failing the task.

Milestone 3: Cross-Agent Hops & Crucial Safety Rails

  • PR #807 (M3): Enabled agent-to-agent dispatch (Rule 2 reversal). Previously, only mentions authored by rrs (the human) would trigger execution. With M3, an authenticated comment from @claude mentioning @grok triggers Grok’s headless launcher.
  • PR #811 (M3.1): Set --permission-mode bypassPermissions for headless Claude Code so non-interactive runs execute tool calls without stalling on TTY prompts.
  • PR #812 (M3.2): Restricted agent summon parsing to line-initial @login tokens with a non-empty task description (#810), preventing accidental dispatches from passive conversational references.

Milestone 4: Directives, Specification & Living Documentation

  • PR #815 (M4): Aligned CAMP fleet directives, architecture specifications, and user documentation with the live A2A implementation.

Milestone 5: Concurrent Dispatching & Hop-Cap Attribution

  • PR #816: Stamped hop-cap notices under a dedicated system bridge identity and automatically applied the needs-human label on held threads.
  • PR #817 (Threaded Scheduler): Replaced the single-threaded serial dispatcher with a concurrent thread-pool scheduler (#804). Multi-agent dispatches across different issues now execute concurrently in parallel background threads instead of queuing behind long-running tasks.

Milestone 6: Full Fleet Coverage with GitHub Copilot

  • PR #819 (M6): Brought GitHub Copilot CLI into the headless A2A fleet (#818). By passing --allow-all-tools and pinning minted session UUIDs (--session-id=<uuid>), Copilot achieved full parity with Claude, Grok, and Antigravity, completing 100% headless fleet coverage across all four major AI coding assistants.

5. Hard Safety Rails: Preventing Autonomous Runaway Loops

Letting AI agents autonomously invoke each other in background loops without a human watching is a recipe for an infinite, credit-draining token fire. We put four non-negotiable safety guardrails in place:

Guardrail 1: The Strict Hop Cap

The dispatcher tracks hops per (repo, issue). Each agent-to-agent dispatch increments the counter.

  • Hop Limit = 3: A typical review round-trip is 2 hops (Human $\rightarrow$ Claude $\rightarrow$ Grok $\rightarrow$ Claude).
  • Automatic Halt on Hop 4: If agents attempt a 4th autonomous hop without human participation, the bridge refuses to launch, posts a diagnostic notice to the thread: [camp-a2a-bridge] hop cap reached (3 agent-to-agent dispatches on CAMP/camp-infrastructure#813) β€” not launching GRK for claude's mention, and holds execution until the human (rrs) provides input or resets the count.

Guardrail 2: Deliberate Summon Parsing (M3.2, #810 / PR #812)

In human conversation, we often reference colleagues in passing: β€œI will talk to @claude about this later” or β€œSee @grok’s table above”. Early prototypes treated any appearance of @agent as a dispatch trigger, causing accidental, unwanted agent launches!

We instituted a strict Summon Predicate: For fleet agents, a mention is only considered an actionable summon if:

  1. The @login appears as the starting word of a line (optionally preceded by markdown list markers *, -, or >).
  2. It is immediately followed by whitespace and a non-empty task description.

Mid-sentence mentions in discussion paragraphs are parsed as passive conversational text and never trigger background dispatches.

Guardrail 3: Headless Tool Permissions without Weakening Security (M3.1, #809 / PR #811)

In interactive mode, Claude Code presents interactive TTY prompts asking the user to approve MCP tool calls (such as camp_pr_get or camp_pr_get_diff). In unattended headless mode, there is no TTY, causing the run to fail with permission errors.

To fix this, we configured --permission-mode bypassPermissions for Claude’s headless CLI invocation. Crucially, this only bypasses Claude’s internal TTY UI promptβ€”it does not bypass CAMP’s security rails.

All command executions still route through camp-acpd and Bubblewrap namespaces; OPA policy checks remain active; and privileged operations (such as merging pull requests or restarting system services) still trigger desktop Zenity HITL dialogs on the human’s workstation.

Guardrail 4: The Sovereign Kill Switch (Rule 1)

At any point, the human operator can instantly freeze all background agent dispatches across the entire infrastructure with a single standard Linux command:

systemctl --user stop camp-a2a-active.service

6. Live Dogfooding: Watching the Swarm in Action

On August 27, 2026, on issue CAMP/camp-infrastructure#813, we ran the full live dogfood test of the A2A system.

Here is the exact transcript of what took place entirely autonomously in the Gitea issue thread:

  1. Human initiates: rrs comments on issue #813:

    @claude Please start the M3 dogfood. On this issue, post a conversation comment whose first line is exactly: @grok Please review this issue in one short paragraph, then stop.

  2. Claude launches (Cold start): The dispatcher spins up @claude headlessly inside bwrap. Claude reads the issue and posts:

    @grok Please review this issue in one short paragraph, then stop.
    (M3 dogfood step 2 β€” posted by @claude on rrs’s instruction; this is the CLD $\rightarrow$ GRK fleet hop.)

  3. Grok launches (Cold start, Hop 1): The bridge intercepts Claude’s comment, identifies the start-of-line @grok summon, and launches @grok. Grok reviews the issue and replies:

    @claude I have reviewed this issue. Please confirm and stop.
    #813 is a throwaway live dogfood of A2A M3 on 6.git+b78c65cf…

  4. Claude resumes (Session Resume, Hop 2): The bridge intercepts Grok’s comment, sees the @claude summon, and launches Claude with --resume b398d048-ccc3-4cce-8437-4cf8748881a8. Claude immediately remembers its earlier context without token waste:

    Confirmed — Grok's review (comment 88562) received via the GRK→CLD fleet hop. That completes the round trip: rrs→CLD, CLD→GRK, GRK→CLD, and this reply. I am deliberately not tagging anyone here, so the chain stops at two agent hops. Stopping.

  5. Testing the Hop Cap (Hop 3 $\rightarrow$ 4): grok prompts @claude Please ack hop four then stop. Claude posts @grok Please ack hop four then stop. (Hop 3). When Grok would have been launched for Hop 4, the dispatcher intervenes:

    [camp-a2a-bridge] hop cap reached (3 agent-to-agent dispatches on CAMP/camp-infrastructure#813) β€” not launching GRK for claude's mention.

  6. Human Reset & Multi-Agent Wrap-up: rrs steps in, resets the state, and asks the fleet for final status. In parallel:

    • @grok delivers a closure scorecard.
    • @claude confirms session continuity and M3.2 summon filtering.
    • @priyasi (Antigravity CLI) runs automated ACP checks: 44/44 test suite passing, 17,219 MemPalace vector drawers active, zero spec drift.
    • @agrickxy (Antigravity CLI) provides comprehensive infrastructure impression analysis.
    • @kiran (Antigravity CLI) is summoned headlessly to draft this very blog post!

7. The Ergonomic Breakthrough: The Forge as the Unified Mindmap & Interface

Beyond backend plumbing and sandboxing, routing agent interaction through Gitea fundamentally revolutionizes the developer experience of managing an AI fleet.

The β€œMindmap” Mental Model: Threaded Conversations & Forking Tasks

In traditional CLI tools, conversations are constrained to a single, linear terminal scrollback. When an agent discovers multiple sub-problems, exploring them sequentially in one prompt loop rapidly pollutes the context window and confuses the model.

Using the forge as the communication gateway naturally unlocks a mindmap mental model:

  • Forking sub-threads: Complex problems can be split into dedicated child issues or threaded PR reviews.
  • Focused execution scopes: An agent can be summoned to solve a narrow sub-task in its own issue thread without derailing the parent architectural discussion.
  • Structured problem decomposition: The forge issue hierarchy maps 1:1 to the developer’s mental map of the project.

Eliminating Terminal UI Fragmentation

Anyone using multiple AI coding assistants on a daily basis quickly grows exhausted by their jarring terminal UI differences: differing ANSI escape rendering, inconsistent markdown wrapping, erratic diff pagers, and incompatible keybindings across Claude, Grok, and Antigravity.

Gitea homogenizes the entire fleet under a single, polished rich-text web view:

  • Syntax-highlighted code blocks and visual side-by-side git diffs.
  • Clear author badges attributing each contribution to its exact agent identity (@claude, @grok, @priyasi, @kiran).
  • Collapsible <details> blocks for voluminous diagnostic outputs.
  • Interactive task lists and markdown tables.

Effortless Context Retrieval, Archival & Data Retention

Auditing past agent decisions in terminal logs or ephemeral chat histories is notoriously difficult. With the forge, every exchange is:

  • Contextually bound: Pinned directly to the repository, branch, and commit SHA being modified.
  • Organized & Archival-Grade: Full-text searchable with clear milestone and issue tags.
  • Topic-Focused: The human operator can review the complete lifecycle of a discussion in seconds, gaining a rapid, holistic grasp on the entire subject.

Reading back through past agent interactions becomes a breezeβ€”to the point where interacting via the intermediary Gitea interface becomes far more pleasant and productive than wrestling with multiple desktop CLI terminals.

Remote Connectivity & Headless Agent Farm Management

Because Gitea provides a standard web and API interface, you are no longer chained to the workstation running the agent processes:

  • Monitor progress and dispatch tasks from a mobile browser, tablet, or remote laptop.
  • Queue review tasks on the go without requiring active SSH sessions or terminal multiplexers.
  • The local agent farm continues working silently in its sandboxed daemon containers.

Quietly Achieving the Holy Grail: Live Cross-Vendor Swarms

For years, the AI industry has treated cross-vendor multi-agent interoperability as an elusive dream waiting for industry-wide API standardization. By recognizing the software forge as the universal message bus, we quietly achieved live, production-grade, cross-vendor communication across completely distinct vendor models.


8. What This Means for the Future of Agentic AI

This milestone marks a fundamental shift in how we interact with autonomous AI systems:

  1. Heterogeneous Agent Specialization: We don’t have to choose a single β€œwinner” among AI models. We can task Claude Code with architectural refactoring, summon Grok Build for rapid verification and adversarial PR reviews, and deploy Google Antigravity agents for codebase exploration and documentation draftingβ€”all coordinating fluidly in the same PR thread.
  2. True Human Sovereignty: The human developer is no longer a bottleneck typist or a passive spectator. You act as the Engineering Manager / Lead Architect. You set the requirements on an issue, tag the lead agent, and let the agents iterate, review, and test among themselves in the threadβ€”while hard hop caps, OPA policies, and Zenity HITL gates guarantee that no agent merges code or pushes upstream without your explicit sign-off.
  3. No Vendor Lock-In: Because the entire coordination fabric is built on standard Git, HTTP webhooks, local Linux container sandboxes (bwrap), and open MCP tools, any new AI CLI tool released tomorrow can be plugged into our fleet in under 15 minutes by simply adding its command-line prompt flag to the launch table.

We have moved beyond static autocomplete and interactive chat widgets. The software forge is now an active, living, collaborative workspace where humans and autonomous AI agents engineer software together.


9. Video Demonstration: CAMP Forge A2A Swarm in Action

Below is a video demonstration showcasing autonomous multi-agent communication, cross-vendor relay, and headless swarm coordination in action via the CAMP Forge interface:


The Cross-Agent Memory Protocol (CAMP) and MemPalace are developed as part of our ongoing research into secure, sovereign, and disciplined Agentic AI computing.

Russ Allbery: Review: The Hands of the Emperor

31 Augustus 2026 om 05:11

Review: The Hands of the Emperor, by Victoria Goddard

Series: Lays of the Hearth-Fire #1
Publisher: Underhill Books
Copyright: January 2019
ISBN: 1-988908-15-9
Format: Kindle
Pages: 739

The Hands of the Emperor is a self-published political fantasy novel. It's the recommended first book (although not the first published book) in a complicated set of interrelated series. I was not able to definitively confirm that Underhill Books is Goddard's self-publishing press name, but the press does not appear to have an Internet presence apart from Goddard's books and her books appear to be using the standard self-publishing channels.

Cliopher Mdang is the personal secretary of the last emperor of Astandalas, the magical heart of Zunidh, a man worshiped as a god. The emperor's word is absolute, his magic supports the health of the entire world, and he cannot be physically touched without risking physical damage and severe political and religious punishment. Cliopher is one of the emperor's closest associates, but the distance between them is still vast. It therefore represents a terrifying and dangerous breach of etiquette for him to suggest the emperor may enjoy a vacation on a tropical island near Cliopher's remote home. The emperor's acceptance of the invitation is even more startling.

The emperor has opinions about his life as the emperor that no one had guessed. Cliopher has not assimilated as completely into the bureaucratic machinery of the empire as it first may appear. And Cliopher's family have vastly misunderstood the nature of his role in the emperor's government.

I find the marketing blurb for this book unfortunate since, at least to me, the emphasis on physical touch and intimacy implies that The Hands of the Emperor is a romance novel or at least has significant romantic elements. I've been aware of this book for years but put off reading it because I wasn't quite in the mood for that story. This is not a romance novel; there is no romance in this book whatsoever. It is a political fantasy, both in the sense that it is set in a secondary fantasy world with magic and (apparently) some form of interplanetary travel, and in the sense that it is a fantasy of governance.

When I say that this book blew up in certain corners of the Internet during the pandemic, I think you will still underestimate the passion of its advocates. I heard about this book constantly, in a way that reminded me of Kushiel's Dart and the time when fans of Jacqueline Carey would bring her up in every fantasy conversation, or when we created a Usenet newsgroup for The Wheel of Time mostly to get the voluminous conversations off of the regular SFF newsgroup. I'm one of those mildly contrarian people for whom that degree of enthusiasm is a little off-putting, which is another reason why I resisted buying a copy for years and only read it in 2026.

It's delightful, although also a bit embarrassing, when the book everyone was in love with turns out to be just as good as everyone said it was.

I adore stories about friendship, and this is one of the best stories about friendship that I've ever read. It is a very, very slow burn, but I also thought the first three quarters of the book was exquisitely paced. There were long sections where not very much was happening, and yet I couldn't put the book down because there was so much subtle character work just beneath the surface.

Almost all of the novel is told in tight third person from Cliopher's perspective, and I thought that was an excellent choice. Neither Cliopher nor the narrator comment on things that Cliopher finds obvious, which is both immersive and critical to the pacing. There are discoveries for the reader throughout the book, the sort of discoveries that make pieces fit together satisfyingly in retrospect, and the reader stays sufficiently ahead of the misunderstandings of Cliopher's friends and family that one also gets the joy of watching other people discover things that one figured out a hundred pages earlier.

It helps that I truly liked nearly everyone in this book. There are no real villains, only a few supporting characters whose role is to be irritating or corrupt. If you're looking for a lot of conflict and drama, you may want to save this book for a different mood, but if you're in the mood for a varied collection of fundamentally good characters working methodically through the complexities and obstacles of politics and social systems to improve the world, there are few books I would recommend more. Goddard achieves one of the hardest tricks of slow burns: steady forward progress that does not rely on reversals, misunderstandings, or the friendship equivalent of the third-act breakup. This book spends 700 pages building towards a climax that managed to be worthy of all 700 pages without ever annoying me with artificial obstacles, and that's quite a feat.

I've not said much about the details of the plot. There is one β€” it's not just character work β€” but I think this book benefits immensely from going in as blind as possible. I found the twists and turns and growing revelations so deeply satisfying that I don't want to rob any other reader of the experience.

The fantasy world-building is intriguing but a bit unsatisfying because it is so unexplained. We get a few details of the magic system, but since Cliopher has no magic, he isn't that interested in the details. There is a catastrophic magical event in the world background, and we learn some of the details of its practical effects, but the nature of the world before the cataclysm is so obvious to the characters that it's never explained. I'm not even certain that this civilization is interplanetary; that feels like the implication of how characters talk about multiple worlds, but the method of travel is left entirely undefined. This might be frustrating to some genre readers, but I personally enjoy books where the world-building is a bit mysterious. It's a good reason to read more of Goddard's books set in the same universe.

This was my favorite of the books I've read so far this year, but I do have one caution and a couple of caveats.

The caution is that Cliopher comes from an island culture based heavily on (I think) Polynesian cultures. That culture is very central to the story and is treated with considerable respect, but I still get a bit nervous when a Canadian author from Nova Scotia with an academic background in European medieval studies writes a story focused this deeply on a non-European culture. Nothing about her portrayal seemed off to me (although there is a very clunky and ham-handed scene about a different native culture that worries me), and for all I know she has family background or other connections to the culture she is borrowing from, but it's possible I missed serious problems.

The flip side of that caution is that I'm delighted to see a fantasy author drawing on a non-European culture, and I thought the clash of cultures was very well-handled.

The first caveat is that the story is very focused on good governance, but both the process and the details of that governance are not going to satisfy someone reading primarily for the politics. The policies and reforms are very standard 21st century progressive material that felt a bit out of place in a quasi-medieval world with magic and airships. Their implementation is not the point of the story, and is therefore heavily backgrounded, but that means Goddard barely mentions the inevitable practical implementation difficulties and does not discuss how they're overcome.

The world structure also means that Goddard can make use of the favorite cheat of political reformers in fiction: Absolute monarchy lets you enact a political agenda without having to do the hard and frustrating work of persuasion or political (or actual) warfare. This objection is not entirely fair because we do get some memorable scenes of persuasion, but the political portion of the plot is unrealistically devoid of setbacks or resistance that goes beyond token arguments.

Whether this will bother you will depend heavily on what parts of the book you'd rather focus on. I can see why this was such a popular pandemic read: The Hands of the Emperor is focused tightly on the joy of competent people fixing things and does not focus on the arguments, division, or polarization. The heart of the book is the friendship and characterization of some deeply admirable people, and the political reform is incidental background material. I suspect this is the right choice for readers who aren't political junkies, but I kept having the niggling objection that the politics felt a bit too pat and simplistic. Goddard stressed that the characters were investing considerable effort, but even still, it is not this easy to change the direction of a political system and idealistic plans usually do not work out this neatly.

The second caveat is that, as previously mentioned, I thought the pacing was excellent for about three quarters of the book. Goddard is building towards a grand climax, and I think she built a little too much and tried to make the climax a bit too grand and risked over-egging the pudding. That made the payoff feel a bit belabored to me. I still enjoyed it, and parts of it are wonderfully emotional, but I think the ending might have been stronger if Goddard had dialed Cliopher back just a little and tightened up the climax a touch. That said, this book fully commits to being a sprawling slow burn and that's part of its appeal, so it's probably better for Goddard to err in that direction than it would have been to cut short the denouement.

This is one of those books that I'm not sure would exist without self-publishing. It's a little too long, a little too political in the wrong ways, a little too devoid of the typical sorts of conflicts expected in a fantasy book, and too determined to be its own peculiar thing. I think it would scare off publishers. Unlike some self-published books, though, I didn't notice any obvious editing flaws or lack of polish. It's one of those glorious novels that is so very much its own type of story that it provides an experience that would be hard to replicate with another book.

I was so deeply satisfied by this book. It's a wish-fulfillment political fantasy full of diligent restraint and competence porn, so you have to be in the mood for that. This is not the book to read when you're feeling cynical, or are in the mood for action and high drama. But if you're in the mood for a long, slow, open-hearted story of friendship that offers the fantasy of giving truly good people enough power to be effective, I highly recommend this one.

Followed in the direct sequel sense by At the Feet of the Sun, but there is a very complex story progression in this world that I think I'd have to read all the other books to understand. This was such a satisfying and complete experience that I'm not in a hurry to figure out which Goddard book to read next, but I'm sure I'll be returning to this world at some point.

Rating: 9 out of 10
