What is assembly-orchestrator?

A workflow coordinator for improving MCP tools, the interfaces agents use to call external capabilities. It coordinates analysis, design, approval, implementation, testing, and release.

Use it to analyze API coverage, design or add MCP tools, implement changes, run evaluations and benchmarks, review security, synchronize documentation, and publish updates.

It keeps a multi-stage tool change organized and ensures that design approval, tests, documentation, and deployment are not skipped.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00032	$0.00565
Opus 5.5	$0.00013	$0.00226
Sonnet 5.5	$0.00006	$0.00113
Haiku 4.5	$0.00003	$0.00056

Security

Grade A, and why

assembly-orchestrator scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Assembly Orchestrator Skill

MCP 도구 개선의 전체 워크플로를 조율합니다: 분석 → 설계 → 승인 → 구현 → 검증 → 배포.

트리거

"MCP 도구를 개선해줘"
"API 커버율을 높여줘"
"새 API를 통합해줘"
"도구 구조를 최적화해줘"

워크플로

Phase 1: 분석 (api-analyst)
  └── 현황 파악 → 갭 분석 → 통합 기회 도출

Phase 2: 설계 (tool-designer)
  └── 파라미터 스키마 → description → Lite/Full 배분

Phase 3: 승인
  └── 사용자에게 설계 제안 → 승인 대기

Phase 4: 구현 (mcp-developer)
  └── 코드 작성 → 빌드 → 테스트

Phase 5: 검증
  └── Eval 실행 → 성능 벤치마크 → 보안 검토

Phase 6: 배포
  └── 문서 동기화 → 커밋 → fly deploy → npm publish

실행 규칙

모든 에이전트는 model: opus 사용
중간 산출물은 _workspace/ 디렉토리에 저장
각 Phase 완료 후 사용자에게 진행 상황 보고
Phase 3 (승인)은 반드시 사용자 확인 후 진행
Breaking change가 있으면 버전업 필수 (기억: feedback_breaking_change)
문서 동기화 필수 (기억: feedback_doc_sync)

사전 점검

실행 전 반드시 확인:

docs/discovered-all-codes.json 존재 여부
docs/tool-mapping.md 최신 여부
npm test 통과 여부
git working tree clean 여부

산출물

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

assembly-orchestrator is a skill published in the GitHub repository hollobit/assembly-api-mcp (94 stars, last pushed 6mo ago), licensed MIT. It adds 32 tokens to every session and 565 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
