plugin-validate	Validate a Slopsmith plugin's plugin.json against the schema and run structural checks. USE WHEN the user asks to validate a plugin, check the manifest, plugin.json errors, lint plugin, verify plugin structure, plugin license check, or audit plugin contract. Runs JSON Schema validation, file-existence checks for declared script/routes/settings.html/tour paths, and license-allowlist check.

plugin-validate

Runs the same checks .github/workflows/validate-plugins.yml + tests/test_plugin_schema.py run in CI, but locally and instantly — useful for catching errors before push.

When to invoke

The user says one of:

• "validate plugins/"
• "check the manifest for X"
• "lint this plugin"
• "verify my plugin.json"
• "plugin license check"

Works on either a specific plugin (e.g. plugins/highway_3d/) or all in-tree plugins if none is specified.

What to run

# All in-tree plugins (default)
python <<'PY'
import json, glob, sys, jsonschema, pathlib
schema = json.load(open('schema/plugin.schema.json'))
jsonschema.Draft202012Validator.check_schema(schema)
ok = True
for path in sorted(glob.glob('plugins/*/plugin.json')):
    plugin_dir = pathlib.Path(path).parent
    plugin_id = plugin_dir.name
    m = json.load(open(path))
    plugin_ok = True  # per-iteration flag so we don't print OK after a later FAIL
    # 1. Schema
    try:
        jsonschema.validate(m, schema)
    except jsonschema.ValidationError as e:
        print(f"FAIL {path}: {e.message} (at {list(e.absolute_path)})")
        ok = False
        continue
    # 2. id == directory name
    if m['id'] != plugin_id:
        print(f"FAIL {path}: id={m['id']!r} but directory is {plugin_id!r}")
        ok = False
        plugin_ok = False
    # 3. Declared files exist
    for field in ('script', 'routes', 'tour'):
        if field in m and not (plugin_dir / m[field]).exists():
            print(f"FAIL {path}: {field}={m[field]!r} but file missing")
            ok = False
            plugin_ok = False
    if 'settings' in m and 'html' in m['settings']:
        h = m['settings']['html']
        if not (plugin_dir / h).exists():
            print(f"FAIL {path}: settings.html={h!r} but file missing")
            ok = False
            plugin_ok = False
    for field in ('settings', 'diagnostics'):
        if field in m and 'server_files' in m[field]:
            for relpath in m[field]['server_files']:
                # server_files paths live under context["config_dir"], NOT the
                # plugin dir, so we don't existence-check them here. We only
                # confirm the path *looks* safe (already enforced by schema).
                if '..' in relpath or relpath.startswith('/') or '\\' in relpath:
                    print(f"FAIL {path}: {field}.server_files contains unsafe path {relpath!r}")
                    ok = False
                    plugin_ok = False
    if plugin_ok:
        print(f"OK   {path}")
sys.exit(0 if ok else 1)
PY

Targeted invocation

If the user names a specific plugin, swap the glob for plugins/<id>/plugin.json and report on just that one.

License-allowlist check

If the user specifically asks for a license check (or the plugin declares license in plugin.json), additionally run:

pytest tests/test_plugin_schema.py::test_schema_license_enum_subset_of_contributing_allowlist -v --noconftest

(or skip --noconftest if structlog is installed locally).

Output

Use the format from the script: OK <path> per validated manifest, FAIL <path>: <reason> per failure. Add a one-line summary:

Result: 3/3 plugins valid (OK app_tour_library, app_tour_settings, highway_3d)

or

Result: 2/3 plugins valid; 1 FAIL (see above)
