Reframe pyro around the chat-host path

Make the docs and help text unapologetically teach  as the product path for Claude Code, Codex, and OpenCode on Linux KVM.

Rewrite the README, install/first-run/integration guides, public contract, vision, and use-case docs around the zero-to-hero chat flow, and explicitly note that there are no users yet so breaking changes are acceptable while the interface is still being shaped.

Update package metadata, CLI help, and the docs/help expectation tests to match the new positioning. Validate the reframe with usage: pyro [-h] [--version] COMMAND ...

Validate the host and serve disposable MCP workspaces for chat-based coding agents on supported Linux x86_64 KVM hosts.

positional arguments:
  COMMAND
    env        Inspect and manage curated environments.
    mcp        Run the MCP server.
    run        Run one command inside an ephemeral VM.
    workspace  Manage persistent workspaces.
    doctor     Inspect runtime and host diagnostics.
    demo       Run built-in demos.

options:
  -h, --help   show this help message and exit
  --version    show program's version number and exit

Suggested zero-to-hero path:
  pyro doctor
  pyro env list
  pyro env pull debian:12
  pyro run debian:12 -- git --version
  pyro mcp serve

Connect a chat host after that:
  claude mcp add pyro -- uvx --from pyro-mcp pyro mcp serve
  codex mcp add pyro -- uvx --from pyro-mcp pyro mcp serve

If you want terminal-level visibility into the workspace model:
  pyro workspace create debian:12 --seed-path ./repo --id-only
  pyro workspace sync push WORKSPACE_ID ./changes
  pyro workspace exec WORKSPACE_ID -- cat note.txt
  pyro workspace diff WORKSPACE_ID
  pyro workspace snapshot create WORKSPACE_ID checkpoint
  pyro workspace reset WORKSPACE_ID --snapshot checkpoint
  pyro workspace shell open WORKSPACE_ID --id-only
  pyro workspace service start WORKSPACE_ID app --ready-file .ready --                 sh -lc 'touch .ready && while true; do sleep 60; done'
  pyro workspace export WORKSPACE_ID note.txt --output ./note.txt, usage: pyro mcp serve [-h] [--profile {vm-run,workspace-core,workspace-full}]

Expose pyro tools over stdio for an MCP client. Bare `pyro mcp serve` now starts `workspace-core`, the recommended first profile for most chat hosts.

options:
  -h, --help            show this help message and exit
  --profile {vm-run,workspace-core,workspace-full}
                        Expose only one model-facing tool profile. `workspace-
                        core` is the default and recommended first profile for
                        most chat hosts; `workspace-full` is the larger opt-in
                        profile. (default: workspace-core)

Default and recommended first start:
  pyro mcp serve

Profiles:
  workspace-core: default for normal persistent chat editing
  vm-run: smallest one-shot-only surface
  workspace-full: larger opt-in surface for shells, services,
    snapshots, secrets, network policy, and disk tools

Use --profile workspace-full only when the host truly needs those
extra workspace capabilities., and uv run ruff check .

# Install
`pyro-mcp` is built for chat-based coding agents on Linux `x86_64` with KVM.
This document is intentionally biased toward that path.
`pyro-mcp` currently has no users. Expect breaking changes while the chat-host
flow is still being shaped.

## 5. Connect a chat host
## 5. Continue into the stable workspace path
The commands below use plain `pyro ...`. Run the same flow with `uvx --from pyro-mcp pyro ...`
for the published package, or `uv run pyro ...` from a source checkout.
```bash
uv tool install pyro-mcp
WORKSPACE_ID="$(pyro workspace create debian:12 --seed-path ./repo --name repro-fix --label issue=123 --id-only)"
pyro workspace list
pyro workspace update "$WORKSPACE_ID" --label owner=codex
pyro workspace sync push "$WORKSPACE_ID" ./changes
pyro workspace file read "$WORKSPACE_ID" note.txt --content-only
pyro workspace patch apply "$WORKSPACE_ID" --patch-file fix.patch
pyro workspace exec "$WORKSPACE_ID" -- cat note.txt
pyro workspace snapshot create "$WORKSPACE_ID" checkpoint
pyro workspace service start "$WORKSPACE_ID" web --ready-file .web-ready -- sh -lc 'touch .web-ready && while true; do sleep 60; done'
pyro workspace reset "$WORKSPACE_ID" --snapshot checkpoint
pyro workspace export "$WORKSPACE_ID" note.txt --output ./note.txt
pyro workspace delete "$WORKSPACE_ID"
```
This is the stable persistent-workspace contract:
- `workspace create` seeds `/workspace`
- `workspace create --name/--label`, `workspace list`, and `workspace update` make workspaces discoverable
- `workspace sync push` imports later host-side changes
- `workspace file *` and `workspace patch apply` cover model-native text inspection and edits
- `workspace exec` and `workspace shell *` keep work inside one sandbox
- `workspace service *` manages long-running processes with typed readiness
- `workspace snapshot *` and `workspace reset` make reset-over-repair explicit
- `workspace diff` compares against the immutable create-time baseline
- `workspace export` copies results back to the host
- `workspace stop|start` and `workspace disk *` add secondary stopped-workspace inspection and raw ext4 export
When that stable workspace path is working, continue with the recipe index at
[use-cases/README.md](use-cases/README.md). It groups the five core workspace stories and the
real smoke targets behind them, starting with `make smoke-use-cases` or one of the per-scenario
targets such as `make smoke-repro-fix-loop`.
Treat `make smoke-use-cases` as the trustworthy guest-backed verification path for the advertised
workspace workflows.
## 6. Optional demo proof point
```bash
uvx --from pyro-mcp pyro demo
```
`pyro demo` proves the one-shot create/start/exec/delete VM lifecycle works end to end.
Example output:
```json
{
"cleanup": {
"deleted": true,
"reason": "post_exec_cleanup",
"vm_id": "..."
},
"command": "git --version",
"environment": "debian:12",
"execution_mode": "guest_vsock",
"exit_code": 0,
"stdout": "git version ...\n"
}
```
For a fuller copy-pasteable transcript, see [first-run.md](first-run.md).
When you are done evaluating and want to remove stale cached environments, run `pyro env prune`.
## Installed CLI
If you already installed the package, the same evaluator path works with plain `pyro ...`:
```bash
uv tool install pyro-mcp
pyro --version
pyro doctor
pyro env list
pyro env pull debian:12
pyro run debian:12 -- git --version
```
After the CLI path works, you can move on to:
- persistent workspaces: `pyro workspace create debian:12 --seed-path ./repo`
- workspace discovery metadata: `pyro workspace create debian:12 --name repro-fix --label issue=123`
- workspace discovery commands: `pyro workspace list` and `pyro workspace update WORKSPACE_ID --label owner=codex`
- live workspace updates: `pyro workspace sync push WORKSPACE_ID ./changes`
- guest networking policy: `pyro workspace create debian:12 --network-policy egress`
- workspace secrets: `pyro workspace create debian:12 --secret API_TOKEN=expected --secret-file PIP_TOKEN=./token.txt`
- model-native file editing: `pyro workspace file read WORKSPACE_ID src/app.py --content-only`, `pyro workspace file write WORKSPACE_ID src/app.py --text-file ./app.py`, and `pyro workspace patch apply WORKSPACE_ID --patch-file fix.patch`
- baseline diff: `pyro workspace diff WORKSPACE_ID`
- snapshots and reset: `pyro workspace snapshot create WORKSPACE_ID checkpoint` and `pyro workspace reset WORKSPACE_ID --snapshot checkpoint`
- host export: `pyro workspace export WORKSPACE_ID note.txt --output ./note.txt`
- stopped-workspace inspection: `pyro workspace stop WORKSPACE_ID`, `pyro workspace disk list WORKSPACE_ID`, `pyro workspace disk read WORKSPACE_ID note.txt --content-only`, and `pyro workspace disk export WORKSPACE_ID --output ./workspace.ext4`
- interactive shells: `pyro workspace shell open WORKSPACE_ID --id-only`
- long-running services: `pyro workspace service start WORKSPACE_ID app --ready-file .ready -- sh -lc 'touch .ready && while true; do sleep 60; done'`
- localhost-published ports: `pyro workspace create debian:12 --network-policy egress+published-ports` and `pyro workspace service start WORKSPACE_ID app --ready-http http://127.0.0.1:8080/ --publish 18080:8080 -- ./start-app`

OpenCode uses the `mcp`/`type: "local"` config shape shown in

`pyro-mcp` is already installed, replace the `uvx --from pyro-mcp pyro`

OpenCode uses the `mcp` / `type: "local"` config shape shown in
[opencode_mcp_config.json](../examples/opencode_mcp_config.json).
Use profile progression like this:
If `pyro-mcp` is already installed, replace `uvx --from pyro-mcp pyro` with
`pyro` in the same command or config shape.
- `workspace-core`: default and recommended first profile for normal persistent chat editing
- `vm-run`: one-shot-only integrations
- `workspace-full`: explicit advanced opt-in when the host truly needs shells, services, snapshots, secrets, network policy, or disk tools
Use `--profile workspace-full` only when the chat truly needs shells, services,
snapshots, secrets, network policy, or disk tools.
## Stable Workspace
## 6. Go from zero to hero
Use `pyro workspace ...` when you need repeated commands in one sandbox instead of one-shot `pyro run`.
The intended user journey is:
1. validate the host with `pyro doctor`
2. pull `debian:12`
3. prove guest execution with `pyro run debian:12 -- git --version`
4. connect Claude Code, Codex, or OpenCode with `pyro mcp serve`
5. start with one use-case recipe from [use-cases/README.md](use-cases/README.md)
6. trust but verify with `make smoke-use-cases`
If you want the shortest chat-first story, start with
[use-cases/repro-fix-loop.md](use-cases/repro-fix-loop.md).
## 7. Manual terminal workspace flow
If you want to inspect the workspace model directly from the terminal, use the
companion flow below. This is for understanding and debugging the chat-host
product, not the primary story.

pyro workspace create debian:12 --seed-path ./repo

pyro workspace create debian:12 --seed-path ./repo --secret API_TOKEN=expected

pyro workspace exec WORKSPACE_ID -- cat src/note.txt
pyro workspace exec WORKSPACE_ID --secret-env API_TOKEN -- sh -lc 'test "$API_TOKEN" = "expected"'
pyro workspace diff WORKSPACE_ID
pyro workspace snapshot create WORKSPACE_ID checkpoint
pyro workspace reset WORKSPACE_ID --snapshot checkpoint
pyro workspace reset WORKSPACE_ID
pyro workspace export WORKSPACE_ID src/note.txt --output ./note.txt
pyro workspace shell open WORKSPACE_ID --secret-env API_TOKEN --id-only

```
Workspace commands default to the persistent `/workspace` directory inside the guest. If you need
the identifier programmatically, use `--id-only` for only the identifier or `--json` for the full
workspace payload. Use `--seed-path`
when the workspace should start from a host directory or a local `.tar` / `.tar.gz` / `.tgz`
archive. Use `pyro workspace sync push` for later host-side changes to a started workspace. Sync
is non-atomic in `4.0.0`; if it fails partway through, prefer `pyro workspace reset` to recover
from `baseline` or one named snapshot. Use `pyro workspace diff` to compare the current workspace
tree to its immutable create-time baseline, `pyro workspace snapshot *` to capture named
checkpoints, and `pyro workspace export` to copy one changed file or directory back to the host. Use
`pyro workspace exec` for one-shot commands and `pyro workspace shell *` when you need an
interactive PTY that survives across separate calls. Prefer
`pyro workspace shell read --plain --wait-for-idle-ms 300` for chat-facing shell loops. Use `pyro workspace service *` when the
workspace needs long-running background processes with typed readiness probes. Service metadata and
logs stay outside `/workspace`, so the service runtime itself does not show up in workspace diff or
export results. Use `--network-policy egress` when the workspace needs outbound guest networking,
and `--network-policy egress+published-ports` plus `workspace service start --publish` when one
service must be reachable from the host on `127.0.0.1`. Use `--secret` and `--secret-file` at
workspace creation when the sandbox needs private tokens or config, and
`--secret-env SECRET_NAME[=ENV_VAR]` when one exec, shell, or service call needs that secret as an
environment variable. Persisted secret files are available in the guest at
`/run/pyro-secrets/<name>`. Use `pyro workspace stop` plus `pyro workspace disk list|read|export`
when you need offline inspection or one raw ext4 copy from a stopped guest-backed workspace, then
`pyro workspace start` to resume it.
When you need deeper debugging or richer recipes, add:
## Contributor Clone
- `pyro workspace shell *` for interactive PTY state
- `pyro workspace service *` for long-running processes and readiness probes
- `pyro workspace create --network-policy egress+published-ports` plus
`workspace service start --publish` for host-probed services
- `pyro workspace create --secret` and `--secret-file` when the sandbox needs
private tokens
- `pyro workspace stop` plus `workspace disk *` for offline inspection
## 8. Trustworthy verification path
The five recipe docs in [use-cases/README.md](use-cases/README.md) are backed
by a real Firecracker smoke pack:
```bash
make smoke-use-cases
```
Treat that smoke pack as the trustworthy guest-backed verification path for the
advertised chat-host workflows.
## Installed CLI
If you already installed the package, the same path works with plain `pyro ...`:
```bash
uv tool install pyro-mcp
pyro --version
pyro doctor
pyro env list
pyro env pull debian:12
pyro run debian:12 -- git --version
pyro mcp serve
```
## Contributor clone
```bash
git lfs install
