name: probe-versjon
description: Report what this probe plugin can actually see from inside a Cowork session - its own manifest version, the resolved value of ${CLAUDE_PLUGIN_ROOT}, and whether python3 can be invoked at all. Use when running the jobbsok Cowork probe, or when the operator asks to check Cowork session mode, host MCP visibility, python3 availability or plugin-root resolution.

# probe-versjon

This skill exists to answer three of the four questions in
`docs/cowork-probe.md`. It measures; it decides nothing.

Run all three checks and report each result verbatim. Do not summarise, do not
infer a result you did not observe, and do not fill in a value from memory of
how plugins usually behave — an unmeasured answer is worse than no answer here,
because the whole point of the probe is that these behaviours are unknown on
this machine.

## 1. Manifest version

Read `${CLAUDE_PLUGIN_ROOT}/.claude-plugin/plugin.json` and report the `version`
field. Expected: `0.0.1`. A different value means the session served a cached or
different build, and every other result below is about that other build.

## 2. Plugin-root resolution

Report the value `${CLAUDE_PLUGIN_ROOT}` resolved to.

- If it is an absolute filesystem path: the answer to `- CLAUDE_PLUGIN_ROOT:` is `ja`.
- If it is the literal, unexpanded string `${CLAUDE_PLUGIN_ROOT}`, or empty: the answer is `nei`.

## 3. python3 invocation

Run exactly:

```bash
python3 -c 'import sys; print(sys.version)'
```

Report whether the command ran and what it printed.

- If it ran: the answer to `- python3:` is `ja`, followed by the reported version.
- If it could not run (no such command, blocked, sandbox refusal): the answer is
  `nei`, followed by the error text.

## Reporting

Print the three results as a block the operator can copy into
`docs/cowork-probe.md`:

```
- python3: <ja|nei> <version or error>
- CLAUDE_PLUGIN_ROOT: <ja|nei> (<resolved value>)
manifest version: <value>
```

The fourth question (`- Host-MCP:`) is not this skill's to answer: it is about
whether the `probe-tools` connector appears in the session, which the operator
reads off the Cowork UI and confirms by calling `probe_ping`.
