AIhaus 0.3.0 — Agent Delegation + Adversarial Review + Multimodal Attachments

What's New

AIhaus v0.3.0 activates the 41-agent catalog. Previously, 27 agents had no invocation path — skills did specialist work inline. This release makes skills thin orchestrators that delegate to the right specialist, applies BMAD-style adversarial review at every meaningful gate, and persists multimodal context (pasted images, files) so subagents and future sessions never lose it.

Three Major Changes

1. Skill-to-Agent Delegation Mandate

Skills no longer do specialist work inline.

Skill	Previously (inline)	Now (delegated)
/aih-bugfix	Manual grep/read/trace triage	debugger agent (scientific method, hypothesis testing) + test-writer + code-reviewer/code-fixer loop
/aih-feature	Self-review checklist	code-reviewer + code-fixer (severity-gated) + verifier (goal-backward) + conditional integration-checker
/aih-plan	Inline codebase research	assumptions-analyzer + pattern-mapper + conditional phase-researcher + adversarial plan-checker
/aih-quick	Inline self-review	Single-pass code-reviewer (no fix loop)
/aih-run	Basic milestone pipeline	Now always runs verifier + integration-checker after stories; systematic security-auditor on sensitive milestones

2. Adversarial Review Contract (BMAD-inspired)

Five review-role agents now operate under a mandatory problem-finding contract:

"Your review fails if you return zero findings without written justification. Operate with cynical stance. If after thorough analysis you find nothing, you MUST explicitly list what you checked and flag anything you could not verify."

Propagated to: code-reviewer, verifier, integration-checker, security-auditor (plan-checker already conformed). Recorded as ADR-002 in DECISIONS.md.

3. Multimodal Attachment Persistence

Paste screenshots/mockups or drop files during any scoping or execution command. They now:

• Persist under .aihaus/[artifact-dir]/attachments/[seq]-[desc].[ext]
• Catalogue in the artifact's ## Attachments section (path + description)
• Hand off across /aih-plan-to-milestone (plan → draft) and /aih-run (draft → milestone dir)
• Reach agents via an Attachments block in every spawned agent prompt; multimodal-capable agents (analyst, product-manager, architect, debugger, ux-designer, code-reviewer) have a ## Multimodal Context protocol line that makes them Read the files when relevant

Survives across sessions and /aih-resume. Recorded as ADR-003 in DECISIONS.md.

Upgrading

/aih-update

Restart Claude Code after updating. No skill/agent count changes — still 12 skills, 41 agents — so no new discoverability work required.

Breaking Changes

None. All changes are additive or replace inline work with agent delegation. Behavior is richer (adversarial review surfaces more findings) and slightly slower (delegated agents spin up). Iteration caps (2 rounds for code-review+fix, 3 for debugger) keep cost bounded.
