Summary

tools/validate_skills.py says skills.sh.json follows the skills.sh schema, then type-checks notGrouped and the bundle fields. It did not type-check $schema or schema. The published schema types both as string. A number or a list still exited 0.

Change

A present non-string value is now a FAIL. Absence is still allowed. A string is still allowed. format: uri is not asserted.

Evidence

• base: d1202320f3938afc93982eed1a530e5236a9f985 (fork main; tree matches intel/skills 6e609e2dcc95af8047aab0f14d6bc688e2034906)
• command: python3 tools/validate_skills.py --self-test
• before: exit 1, FAIL --self-test: non-string $schema was accepted; non-string schema was accepted. The same file with "$schema": 1 and "schema": ["not-a-uri"] made python3 tools/validate_skills.py exit 0.
• after: exit 0, PASS --self-test: non-string skills.sh schema fields are rejected. The mutated file then exited 1 with FAIL skills.sh.json: $schema must be a string, got int and FAIL skills.sh.json: schema must be a string, got list. The live file still exited 0.
• not claimed: URI format validation, a skills.sh page render, skill efficacy, or a pull request on intel/skills. Not re-run after this blast-radius pass. Current main still has no schema must be a string check.

Blast radius

The change is tools/validate_skills.py only. No skill body changes. The live skills.sh.json still passes. A number or a list in $schema or schema fails the validator. URI format is not checked.
