# Phase 3: Foundation Skills Verification Report

**Phase Goal:** Two foundation skills (harness-design-system and harness-accessibility) exist as complete skill definitions in both platform directories, pass all schema/structure/parity tests, and are discoverable by the slash-command generator.
**Verified:** 2026-03-19T18:10:00Z
**Status:** passed
**Re-verification:** No -- initial verification

| (none) | -    | -       | -        | No TODO, FIXME, PLACEHOLDER, or stub patterns found in any of the 4 skill files |

### Notes

**cognitive_mode field not in schema:** Both skill.yaml files declare `cognitive_mode` (constructive-architect and meticulous-verifier respectively), but the `SkillMetadataSchema` in `agents/skills/tests/schema.ts` does not include this field. Zod's default `z.object()` behavior strips unknown keys during `parse()` and ignores them during `safeParse()`, so tests pass. This means `cognitive_mode` is present in the YAML but is not schema-validated. This is an informational finding -- it does not block Phase 3's goal, but the schema should be updated in a future iteration to include `cognitive_mode` if it is a required field for skill definitions.

### Human Verification Required

No items require human verification. All truths are verifiable programmatically and have been confirmed.

### Gaps Summary

No gaps found. All 11 observable truths are verified. Both skills exist as complete, substantive definitions with all required sections, pass all schema/structure/parity tests (445 tests), are identical across platforms, reference the shared design knowledge data and graph schema from prior phases, and the full monorepo test suite passes (16/16 tasks).
