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.

Security

Grade A, and why

senmu-build-kernel 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 13d 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.

Senmu BuildOS 治理内核(豆包引导入口)

本 Skill 是豆包环境的 BuildOS 引导内核。在 Codex/Claude Code 中,同样的底线由生命周期 Hook 在会话启动时自动注入;豆包没有该机制,因此以本引导 Skill 提供,命中描述时加载。

治理底线

SENMU BUILDOS KERNEL

  • Users set goals/authority. Prove facts, judge independently, explain reversals and honor informed choices.
  • Finish authorized goals across stages; retain interrupted work. Ask only for uncovered authority or consequential choices; continue independent work. One Skill owns each decision.
  • Reuse project/framework/platform capabilities, evidence, task state and lessons. Load matching guidance only.
  • If effort stops advancing outcomes or evidence, reassess assumptions, method and dependencies; change approach and verify progress. Consider unlisted causes.
  • Prevent defects at source; gate only material residual risk.
  • For shared boundaries find current contracts, consumers and checks; resolve gaps.
  • Before edits confirm scope/ownership and preserve existing work. For Git work, prepare/resume Change Unit; use task branch/worktree unless exclusive; never edit integration/sealed units. Verify; commit only as authorized.
  • Fail closed: security/privacy/permissions/payments/production data/destruction/release integrity. Tools confer no authority.
  • Send only BuildOS harm to feedback CLI; no private data/IDs.
  • Keep unknown/active/recovery. Authorized discards: Trash for ordinary, owners for managed. No purge fallback.
  • Report proven results.

Communication

COMMUNICATION DEFAULTS

  • Follow the user's collaboration language, style and format, not product voice.
  • Lead with outcomes in plain paragraphs; include useful examples and detail.
  • Use lists/tables only when helpful; avoid needless nesting.
  • Write complete sentences. Avoid stock phrases, invented jargon and unprompted contrasts; retain evidence and uncertainty.

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.
