Agent Architect Kit ↔ ThumbGate Bridge

Agent Architect Kit ↔ ThumbGate Bridge

Status: shipped 2026-04-21. Test-backed. CLI-automatable. Safe to recommend publicly.

What this is

agent-architect-kit by @ultrathink-art is a CLAUDE.md + agent-role template kit that persists learnings as per-role markdown files (agents/state/memory/<role>.md). They solve the setup layer. ThumbGate solves the runtime-enforcement layer — PreToolUse hooks that actually block known-bad tool calls instead of hoping the agent reads its memory file.

The two stacks are complementary. A team running architect-kit graduates to ThumbGate when their markdown memory grows past the ~80-line ceiling their own memory-directive.md enforces, or when they want their operations meta-agent to do more than edit instructions — actually prevent the failing action.

This bridge turns that graduation into a one-shot command.

The bridge

What it does

scripts/integrations/architect-kit-memory-bridge.js walks an architect-kit memory directory, parses each per-role .md file, and emits one ThumbGate feedback entry per qualifying line:

architect-kit section	→ ThumbGate signal	notes
## Mistakes	down with whatWentWrong	every entry becomes a thumbs-down lesson
## Learnings	up with whatWorked	every entry becomes a thumbs-up memory
## Stakeholder Feedback	up/down depending on keywords	"rejected", "broken", "wrong", "hate", etc. flip negative
## Session Log	skipped	too granular to be useful in a searchable lesson DB

Every ingested entry is tagged architect-kit, role:<name>, and the source section, so imports are auditable and rollbackable.

How to run it

Dry-run first (no writes, prints classification):

npm run integrations:architect-kit:import -- \
  --dir=/path/to/agents/state/memory \
  --dry-run --json

Real import (writes to ThumbGate feedback log):

npm run integrations:architect-kit:import -- \
  --dir=/path/to/agents/state/memory

Single role (e.g. import only coder.md):

npm run integrations:architect-kit:import -- \
  --dir=/path/to/agents/state/memory \
  --role=coder

What you get after import

npm run feedback:stats    # see new entries grouped by tag
npm run feedback:rules    # regenerate prevention rules from the imported mistakes

The imported mistakes now feed the same pipeline as native ThumbGate feedback: lesson DB indexing, Thompson Sampling rollups, prevention-rule generation, and PreToolUse hook injection. The architect-kit operations agent's "edit the instructions" loop is now backed by hooks that can actually refuse a tool call.

Test proof

npm run test:architect-kit-memory-bridge
# 16 tests, 0 fail

Fixtures live in tests/fixtures/architect-kit-memory/ and mirror the exact format from architect-kit's memory-directive.md. The test-suite parity guard (tests/test-suite-parity.test.js) pins this test into the npm test chain — dropping the test accidentally now fails CI.

Positioning talking points (for outreach + docs)

• CLAUDE.md is the control plane. That's architect-kit's thesis and it's right. ThumbGate doesn't replace CLAUDE.md — it adds a runtime gate that enforces whatever CLAUDE.md says.
• Template memory → queryable memory. Per-role markdown files stop scaling past ~80 lines (architect-kit documents this limit themselves). ThumbGate's SQLite+FTS5+LanceDB store is what you migrate to when your memory deserves search.
• Operations becomes teeth, not talk. Their operations meta-agent edits instructions. ThumbGate lets operations also register prevention rules that PreToolUse hooks honor — the same loop, but the agent literally cannot skip it.

What NOT to do

• Do not re-import the same memory twice. Architect-kit memory has no stable entry IDs; repeated imports duplicate lessons. Prune the source file (their own directive says to) before re-running, or run dry-run + diff first.
• Do not import the Session Log section. The bridge skips it deliberately. Session log entries are ephemeral task receipts, not lessons.
• Do not assume operations-role edits propagate automatically. The architect-kit operations agent edits markdown instruction files; ThumbGate's prevention rules are regenerated by npm run feedback:rules. Wire that into your Ralph Loop (or theirs) if you want continuous re-derivation.

When to reach back out to @ultrathink-art

If they ship stable entry IDs in their memory format, upgrade the bridge to do incremental imports (skip already-seen entries). Until then, treat this as a one-shot migration tool, not a sync daemon.
