Every file here was already dark on the forge. This repo has
.hanzo/workflows, so the forge reads that directory and only that one —
251 runs, all cicd.yml — and nothing under .github/workflows has run here
since it landed.
Kept, ported into hanzo.yml: blob-size-policy. The fork added it on
purpose and it is the one gate in the directory that asks a question
answerable without GitHub. It compared HEAD^1 to HEAD^2 — GitHub's
synthetic merge commit, which only exists for a pull_request run — so it
now takes merge-base against origin/main, which resolves the same range
on a PR and to a no-op on a push.
Dropped, and what each cost:
release.yml — the real loss. It published @hanzo/dev and five
per-platform binary packages to npmjs plus a GitHub Release.
Four of the five targets (both darwin, windows-msvc, linux arm64)
need a runner this fleet does not have, so a port would publish one
fifth of a release under a full version number. There is no
automated release for the dev CLI now; hanzo.yml says so where
someone will read it.
release-npm-recovery.yml — manual re-publish of the same packages.
Goes with it.
upstream-merge.yml — merges upstream and opens a PR through the GitHub
API. It was also failing 62 of its last 63 runs on GitHub.
preview-build.yml — builds PR binaries and posts a link as a PR
comment. No comment surface here.
issue-triage.yml, issue-code.yml, issue-comment.yml — issues,
issue_comment and repository_dispatch events driving actions/github-
script against the Issues API. None of that exists on this forge.
rusty-v8-release.yml, v8-canary.yml — bazel V8 builds across macOS,
Windows and Linux, publishing to a GitHub Release.
rust-release-argument-comment-lint.yml — on: workflow_call, and
nothing in the tree calls it. Orphaned.
README.md — described the strategy for the workflows above.
.github/blob-size-allowlist.txt and .github/merge-policy.json stay; only
workflows/ went away.
Hanzo Dev
Hanzo Dev is our coding agent. It runs in your terminal, reads and edits the
repository you point it at, runs commands in a sandbox, and drives a browser
when a task needs one. Models are served by Hanzo AI —
enso and the zen5 family — over the metered gateway at api.hanzo.ai.
It ships inside the Hanzo CLI. hanzo dev is the command.

Install
curl -fsSL https://hanzo.sh | sh
hanzo auth login
hanzo auth login signs you in through Hanzo IAM and links the machine to your
account. Then, from any repository:
hanzo dev
Give it the task on the command line to run headless instead:
hanzo dev "fix the failing tests in ./core and explain what was wrong"
Choosing a model
Model ids come from the gateway, which is the only authority on the catalog — there is no allowlist in the client.
hanzo dev --model enso # our frontier model
hanzo dev --model enso-ultra # the largest reasoning tier
hanzo dev --model zen5-coder # tuned for code
Browse everything available with curl https://catalog.hanzo.ai/v1/models.
Backends
Hanzo Dev is the default and the one we build. The same session launcher can also drive two other agents if you already have them installed, so you can keep one set of habits across all three:
hanzo dev # our agent (default)
hanzo dev claude # or: hanzo code --claude
hanzo dev codex # or: hanzo code --codex
hanzo dev is a spelling of hanzo code dev, not a second implementation —
every spelling resolves through the same launcher.
Options
hanzo dev [OPTIONS] [BACKEND|TASK] [TASK] [-- <PASSTHROUGH>...]
--model <MODEL> Gateway model id, e.g. enso, enso-ultra, zen5-coder
--backend <NAME> dev (default) | claude | codex
--brand <BRAND> Tenant for auth: hanzo | lux | zoo | pars | bootnode
--ask Ask before each action instead of auto-approving (alias: --safe)
--no-sandbox Drop the sandbox and auto-approve. Per-invocation, never persisted
--no-route Call the backend's own model account instead of the metered gateway
--no-mcp Do not attach the Hanzo MCP toolset
--project-mcp Also load the repo's own .mcp.json servers (off by default — a repo is untrusted)
--link / --no-link Stream the session to Hanzo cloud, or never
--resume <ID> Resume a prior linked session by its cloud session id
-c, --config <FILE> Use a specific config file
-v, --verbose Increase logging verbosity
Anything after -- is passed verbatim to the backend.
Two defaults worth knowing. Sessions run sandboxed and auto-approve inside that
sandbox; --ask tightens it, --no-sandbox removes it. Model calls route
through api.hanzo.ai so usage is metered on your Hanzo account; --no-route
sends them to the backend's own account instead.

/branch work on a branch in a worktree
/merge merge the worktree branch back to the default
/model choose model and reasoning effort
/reasoning change reasoning effort (minimal/low/medium/high)
/theme switch color themes
/status session configuration and token usage
/limits weekly and hourly rate limits
/mcp manage MCP servers (status/on/off/add)
/init write an AGENTS.md for this repository
/resume resume a past session for this folder
/new start a new chat
Full list with descriptions: docs/slash-commands.md.
Project context
Run /init in a repository and Hanzo Dev writes an AGENTS.md describing what
it found. Edit that file — it is read at the start of every session in that
directory, so it is where project conventions, architecture notes and "do not
touch this" rules belong.
Tools
The Hanzo MCP toolset is attached by default: filesystem, shell, browser, and
the rest of the Hanzo surface. Add your own servers with /mcp add, or per
repository in .mcp.json — the latter is off unless you pass --project-mcp,
because a repository you just cloned should not get to run a server with your
session's key.

./build-fast.sh is the required check — it must pass cleanly, warnings
included. See DEVELOPING.md and LLM.md for the
workspace layout and the rules that apply inside it.
Contributing
Branch, make the change, make ./build-fast.sh pass, open a pull request.
