Thales Maciel 21a88312b6 Add chat-friendly shell read rendering 
Make workspace shell reads usable as direct chat-model input without changing the PTY or cursor model. This adds optional plain rendering and idle-window batching across CLI, SDK, and MCP while keeping raw reads backward-compatible.

Implement the rendering and wait-for-idle logic in the manager layer so the existing guest/backend shell transport stays unchanged. The new helper strips ANSI and other terminal control noise, handles carriage-return overwrite and backspace, and preserves raw cursor semantics even when plain output is requested.

Refresh the stable shell docs/examples to recommend --plain --wait-for-idle-ms 300, mark the 3.5.0 roadmap milestone done, and bump the package/catalog version to 3.5.0.

Validation: uv lock; UV_CACHE_DIR=.uv-cache make check; UV_CACHE_DIR=.uv-cache make dist-check; real guest-backed Firecracker smoke covering shell open/write/read with ANSI plus delayed output.

Raw Blame History

# First Run Transcript
This is the intended evaluator path for a first successful run on a supported host.
Copy the commands as-is. Paths and timing values will differ on your machine.
The same sequence works with an installed `pyro` binary by dropping the
`uvx --from pyro-mcp` prefix. If you are running from a source checkout instead
of the published package, replace `pyro` with `uv run pyro`.
## 1. Verify the host
```bash
$ uvx --from pyro-mcp pyro doctor
Platform: linux-x86_64
Runtime: PASS
KVM: exists=yes readable=yes writable=yes
Environment cache: /home/you/.cache/pyro-mcp/environments
Capabilities: vm_boot=yes guest_exec=yes guest_network=yes
Networking: tun=yes ip_forward=yes
```
## 2. Inspect the catalog
```bash
$ uvx --from pyro-mcp pyro env list
Catalog version: 3.5.0
debian:12 [installed|not installed] Debian 12 environment with Git preinstalled for common agent workflows.
debian:12-base [installed|not installed] Minimal Debian 12 environment for shell and core Unix tooling.
debian:12-build [installed|not installed] Debian 12 environment with Git and common build tools preinstalled.
```
## 3. Pull the default environment
The first pull downloads an OCI environment from public Docker Hub, requires outbound HTTPS
access to `registry-1.docker.io`, and needs local cache space for the guest image. See
[host-requirements.md](host-requirements.md) for the full host requirements.
```bash
$ uvx --from pyro-mcp pyro env pull debian:12
[pull] phase=install environment=debian:12
[pull] phase=ready environment=debian:12
Pulled: debian:12
Version: 1.0.0
Distribution: debian 12
Installed: yes
Cache dir: /home/you/.cache/pyro-mcp/environments
Default packages: bash, coreutils, git
Install dir: /home/you/.cache/pyro-mcp/environments/linux-x86_64/debian_12-1.0.0
Install manifest: /home/you/.cache/pyro-mcp/environments/linux-x86_64/debian_12-1.0.0/environment.json
Kernel image: /home/you/.cache/pyro-mcp/environments/linux-x86_64/debian_12-1.0.0/vmlinux
Rootfs image: /home/you/.cache/pyro-mcp/environments/linux-x86_64/debian_12-1.0.0/rootfs.ext4
OCI source: registry-1.docker.io/thalesmaciel/pyro-environment-debian-12:1.0.0
```
## 4. Run one command in a guest
```bash
$ uvx --from pyro-mcp pyro run debian:12 -- git --version
[run] phase=create environment=debian:12
[run] phase=start vm_id=...
[run] phase=execute vm_id=...
[run] environment=debian:12 execution_mode=guest_vsock exit_code=0 duration_ms=...
git version ...
```
The guest command output and the `[run] ...` summary are written to different streams, so they
may appear in either order in terminals or capture tools. Use `--json` if you need a
deterministic structured result.
## 5. Continue into the stable workspace path
The commands below use the published-package form. The same stable workspace path works with an
installed `pyro` binary by dropping the `uvx --from pyro-mcp` prefix, or with `uv run pyro` from
a source checkout.
```bash
$ uvx --from pyro-mcp pyro workspace create debian:12 --seed-path ./repo --name repro-fix --label issue=123 --json | tee /tmp/pyro-workspace.json
$ export WORKSPACE_ID="$(python -c 'import json,sys; print(json.load(sys.stdin)["workspace_id"])' < /tmp/pyro-workspace.json)"
$ uvx --from pyro-mcp pyro workspace list
$ uvx --from pyro-mcp pyro workspace update "$WORKSPACE_ID" --label owner=codex
$ uvx --from pyro-mcp pyro workspace sync push "$WORKSPACE_ID" ./changes
$ uvx --from pyro-mcp pyro workspace file read "$WORKSPACE_ID" note.txt
$ uvx --from pyro-mcp pyro workspace patch apply "$WORKSPACE_ID" --patch "$(cat fix.patch)"
$ uvx --from pyro-mcp pyro workspace exec "$WORKSPACE_ID" -- cat note.txt
$ uvx --from pyro-mcp pyro workspace snapshot create "$WORKSPACE_ID" checkpoint
$ uvx --from pyro-mcp pyro workspace service start "$WORKSPACE_ID" web --ready-file .web-ready -- sh -lc 'touch .web-ready && while true; do sleep 60; done'
$ uvx --from pyro-mcp pyro workspace reset "$WORKSPACE_ID" --snapshot checkpoint
$ uvx --from pyro-mcp pyro workspace export "$WORKSPACE_ID" note.txt --output ./note.txt
$ uvx --from pyro-mcp pyro workspace stop "$WORKSPACE_ID"
$ uvx --from pyro-mcp pyro workspace disk list "$WORKSPACE_ID"
$ uvx --from pyro-mcp pyro workspace disk read "$WORKSPACE_ID" note.txt
$ uvx --from pyro-mcp pyro workspace disk export "$WORKSPACE_ID" --output ./workspace.ext4
$ uvx --from pyro-mcp pyro workspace start "$WORKSPACE_ID"
$ uvx --from pyro-mcp pyro workspace delete "$WORKSPACE_ID"
```
## 6. Optional one-shot demo and expanded workspace flow
```bash
$ uvx --from pyro-mcp pyro demo
$ uvx --from pyro-mcp pyro workspace create debian:12 --seed-path ./repo --name repro-fix --label issue=123
$ uvx --from pyro-mcp pyro workspace list
$ uvx --from pyro-mcp pyro workspace update WORKSPACE_ID --label owner=codex
$ uvx --from pyro-mcp pyro workspace sync push WORKSPACE_ID ./changes
$ uvx --from pyro-mcp pyro workspace file list WORKSPACE_ID src --recursive
$ uvx --from pyro-mcp pyro workspace file read WORKSPACE_ID src/app.py
$ uvx --from pyro-mcp pyro workspace file write WORKSPACE_ID src/app.py --text 'print("hi")'
$ uvx --from pyro-mcp pyro workspace patch apply WORKSPACE_ID --patch "$(cat fix.patch)"
$ uvx --from pyro-mcp pyro workspace create debian:12 --network-policy egress
$ uvx --from pyro-mcp pyro workspace create debian:12 --secret API_TOKEN=expected --secret-file PIP_TOKEN=./token.txt
$ uvx --from pyro-mcp pyro workspace exec WORKSPACE_ID --secret-env API_TOKEN -- sh -lc 'test "$API_TOKEN" = "expected"'
$ uvx --from pyro-mcp pyro workspace diff WORKSPACE_ID
$ uvx --from pyro-mcp pyro workspace snapshot create WORKSPACE_ID checkpoint
$ uvx --from pyro-mcp pyro workspace reset WORKSPACE_ID --snapshot checkpoint
$ uvx --from pyro-mcp pyro workspace export WORKSPACE_ID note.txt --output ./note.txt
$ uvx --from pyro-mcp pyro workspace shell open WORKSPACE_ID --secret-env API_TOKEN
$ uvx --from pyro-mcp pyro workspace service start WORKSPACE_ID app --secret-env API_TOKEN --ready-file .ready -- sh -lc 'touch .ready && while true; do sleep 60; done'
$ uvx --from pyro-mcp pyro workspace create debian:12 --network-policy egress+published-ports
$ uvx --from pyro-mcp pyro workspace service start WORKSPACE_ID app --ready-http http://127.0.0.1:8080/ --publish 18080:8080 -- ./start-app
$ uvx --from pyro-mcp pyro mcp serve --profile workspace-core
```
`pyro demo` proves the one-shot create/start/exec/delete VM lifecycle works end to end.

Use `--seed-path` when the workspace should start from a host directory or a local
`.tar` / `.tar.gz` / `.tgz` archive instead of an empty `/workspace`. Use
`pyro workspace sync push` when you need to import later host-side changes into a started
workspace. Sync is non-atomic in `3.5.0`; 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 create
named checkpoints, and `pyro workspace export` to copy one changed file or directory back to the
host. Use `pyro workspace file *` and `pyro workspace patch apply` for model-native text edits,
`pyro workspace exec` for one-shot commands, and `pyro workspace shell *` when you
need a persistent interactive PTY session in that same workspace. Use `pyro workspace service *`
when the workspace needs long-running background processes with typed readiness checks. Internal
service state and logs stay outside `/workspace`, so service runtime data does not appear in
workspace diff or export results. Use `--network-policy egress` for 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. Persisted secret files are
materialized at `/run/pyro-secrets/<name>`, and `--secret-env SECRET_NAME[=ENV_VAR]` maps one
secret into one exec, shell, or service call without storing that environment mapping on the
workspace itself. 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 the same workspace.
The stable workspace walkthrough GIF in the README is rendered from
[docs/assets/workspace-first-run.tape](assets/workspace-first-run.tape) with
[scripts/render_tape.sh](../scripts/render_tape.sh).
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"
}
```
When you are done evaluating and want to remove stale cached environments, run `pyro env prune`.
If `pyro doctor` reports `Runtime: FAIL`, or if the `pyro run` summary does not show
`execution_mode=guest_vsock`, stop and use [troubleshooting.md](troubleshooting.md).
