Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00210 | $0.07824 |
| Opus 5 | $0.00105 | $0.03912 |
| Sonnet 5 | $0.00042 | $0.01565 |
| Haiku 4.5 | $0.00021 | $0.00782 |
Grade A, and why
ultrasafe-synthesizer 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 12d 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.

Synthesizer (cross-axis) — Ultrasafe Attacker Skill v0.2.0
Role: Pre-release simulated penetration testing의 retire-barrier 합성 단독. 7 attacker (agent 1-7) finding 의 cross-axis dedup + severity ranking + correlation + 3-layer report 생성 perspective. Tone: synthesis-meta. 합성 결과의 정확성 > 합성 속도 — BFT quorum 미달 finding 은
low-confidence drafttier 로 강등, fabricate 금지. Position in fan-out: Agent 8 (sink). Phase A (7 attacker 병렬 dispatch) 의 retire-barrier 직후 Phase B 의 informed best-response 단계 (Stackelberg follower, Ultrasafe §3.2) 로 진입. Output:ULTRASAFE_ITERATION_BOUNDARYA2A intent emit (Constellation §13.16) + 3-layer report (OSCAL + Hyperbrief IR + Greatpractice candidate) +clean_signal_4_condition_AND_gate_stateevaluation. v0.2.x advisory mode —value.advisory: trueflag mandatory.
§1 When to invoke
§1.1 Primary triggers
본 skill 은 orchestrator 역할 (메인 에이전트의 Workflow fan-out + MCP ultrasafe_run_fanout — Ultrasafe.md §14.1 역할 매핑) 이 자동 dispatch — 사용자/다른 agent 가 직접 호출하지 않는 게 원칙이에요. 단 다음 시점에 발화:
- Retire-barrier auto-fire: 7 attacker (agent 1-7) 모두
ULTRASAFE_FINDINGemit 완료 + orchestrator 가 finding bag 을 finalize 한 직후. Tier 1-3 모든 release tier 에서 활성. - Iteration boundary close: 현재 iteration N 의 모든 finding 이 수렴 (각 attacker 의 dispatch timeout 도달 또는 explicit
donesignal) — clean-signal-gate 역할 (MCPultrasafe_clean_signal_check) 호출 직전 단계. - Re-synthesis on patch: iteration N 에서 fix 적용 후 iteration N+1 진입 시점 — 직전 boundary snapshot 과 비교한 resolved / regression / persistent / new 4-set diff 계산 강제.
- Forced re-synthesis (Hyperbrief MUST-trigger): meta-safety-broker (Ultrasafe §2.5.2) 가 4 mandatory check 중 하나 hit → broker 가 synthesizer 강제 재실행 요청 (단, broker 자체 hit 결과는 synthesizer 가 외부 fact 로 reference, 합성 결과에 inline 하지 않음 — self-spec-gaming 회피).
- Catalog version change: OWASP LLM Top 10 / MITRE ATT&CK Enterprise / ISO 27001 Annex A 등 reference catalog 의 version bump 감지 시 (
catalog_versionsdiff). 기존 boundary 의coverage_percentage_under_catalog재계산 필요.
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.

ultrasafe-synthesizer is a skill published in the GitHub repository SoliEstre/EstreGenesis (8 stars, last pushed 6d ago), licensed Apache-2.0. It adds 210 tokens to every session and 7,824 once invoked, about $0.0011 per session on Opus 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 2026-08-31.

update-agent-context
This skill should be used to keep CLAUDE.md, AGENTS.md, and the skill files themselves compact, current, and internally consistent. It runs in three phases: Phase 1 performs a one-time structural refactor of CLAUDE.md using a Karpathy-inspired behavioral scaffold and derives AGENTS.md from it by stripping Claude…
watercooler-onboarding
Bootstrap Watercooler memory for a repository by inspecting local code, docs, CI, git history, and existing Watercooler threads, then writing a small set of durable, provenance-backed seed threads that future agents can query and extend. Use when entering a repo for the first time, seeding a repo with Watercooler…
search-threads
Search threads with filters. Supports filters like role:planner, type:Decision, after:2024-01, thread:topic-name, status:OPEN.
ppgp
Portable Persistent Goal Protocol for long-running coding-agent work. Use when starting, resuming, handing off, distilling, or closing a substantial software goal across long sessions, context compaction, agent replacement, or other Agent Skills-compatible coding-agent environments.
