Solutions

1. Provide skill_version as a non-empty string (skillVersion alias accepted).
2. Default to a sentinel like '0.0.0' or 'unversioned' when the skill has no version metadata.
3. Read version from the skill frontmatter/versioning module before recording.

Example fix

// before
recordSkillRun({ skill_id: 'foo', task_description: 'x', outcome: 'success' });

// after
recordSkillRun({ skill_id: 'foo', skill_version: skill.version || '0.0.0', task_description: 'x', outcome: 'success' });

function resolveVersion(skill) {
  const v = skill.version || skill.frontmatter?.version || '0.0.0';
  if (typeof v !== 'string' || v.trim().length === 0) throw new TypeError('skill_version missing');
  return v;
}

function hasSkillVersion(input) {
  const v = input?.skill_version || input?.skillVersion;
  return typeof v === 'string' && v.trim().length > 0;
}

try {
  recordSkillRun(input);
} catch (err) {
  if (/skill_version is required/.test(err.message)) { input.skill_version = '0.0.0'; recordSkillRun(input); }
  else throw err;
}

When it happens

Trigger: recordSkillRun({ skill_id, task_description, outcome }) with no skill_version; skill_version: '' ; skill_version omitted because the skill has no version metadata.

Common situations: Skill lacks a version field in its frontmatter; recording logic read the wrong key; version field left blank during authoring.
