HDD (Deprecated)

SkillDev tools

DEPRECATED — use workflow Stage 2 (spec + frontmatter claims). Historical HDD docs are in docs/decisions/archive/.

Available today. Use it from your connected AI after setup.

Connect ahel once, and every AI you use reads what you have installed.

Then ask your AI: use the HDD (Deprecated) skill

What this skill tells your AI

The instructions your AI receives, as published by kastalien-research/thoughtbox in .agents/skills/hdd/SKILL.md and read by ahel’s review.

Hypothesis-Driven Development with ADR lifecycle is retired. Use:

  1. .claude/skills/workflow/SKILL.md — Stage 2 produces or updates .specs/**/*.md with YAML frontmatter claims (.schemas/spec-v1.json).
  2. PR claimsprs/<branch>.json references spec_claim_id as SPEC-ID:cN.
  3. Historical ADRsdocs/decisions/archive/adr/ (read-only context).

Do not create new files under .adr/.
