Unknown argument: ${arg}

Error message

Unknown argument: ${arg}

What it means

Thrown at the end of skills-health.js parseArgs when a token is not one of the accepted flags (--json, --help, --runs-file <path>, --now <ts>, --dashboard, --panel <name>, --warn-threshold <n>, and their value forms). The parser has no fallback and rejects unrecognized tokens.

Solutions

1. Run `node scripts/skills-health.js --help` to list accepted flags.
2. Correct typos and remove unsupported flags.
3. Confirm --panel names are from the documented set (success-rate, failures, amendments, versions).

Example fix

# before
node scripts/skills-health.js --pannel failures
# after
node scripts/skills-health.js --panel failures

const ALLOWED = new Set(['--json', '--help', '--runs-file', '--now', '--dashboard', '--panel', '--warn-threshold']);
const bad = process.argv.slice(2).filter(a => a.startsWith('--') && !ALLOWED.has(a.split('=')[0]));
if (bad.length) { console.error('Unknown skills-health flag(s):', bad.join(' ')); process.exit(2); }

try { parseArgs(process.argv.slice(2)); } catch (err) { console.error(err.message); process.exit(2); }

When it happens

Trigger: A typo (e.g. `--dashboardd`), a flag from another ECC script, or an unexpected positional argument.

Common situations: Mixing flags across ECC scripts; copy-pasting a stale command; using a long-form alias that is not supported.
