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

log 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 10d 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.

Skill: log

Contract

This skill guarantees:

  • Useful residue from an agent session is persisted as an Activity Contribution, an optional Journal Entry, or both, and when safe as concise updates to affected canonical owner files.
  • /log is a write-back command by default, not a proposal command. Draft mode is used only when {{user_name}} asks for it or when a risky mutation cannot be skipped safely.
  • Der Day Record bleibt der kompakte zeitliche Querschnitt. Activity Contributions belegen materielle Arbeit oder Wirkung; Journal Entries bewahren persönliche Gedanken und Reflexion. Keiner dieser Records wird zur parallelen Projekt- oder Domainwahrheit.
  • Die Record-Formate werden ausschließlich von den registrierten Profilen day-record, activity-contribution und journal-entry sowie den Vorlagen unter system/templates/daily/ bestimmt. Dieser Skill besitzt keine eigene Daily-Vorlage.
  • Concrete tasks, decisions, checks, waiting states, and reassessment needs are routed through task-manager into the atomic Action/Attention records under operations/.
  • Durable project, person, company, deal, finance, content, skill, automation, or interaction truth is updated only in the appropriate owner file and only when the session creates a high-confidence delta.
  • Process-friction or useful-pattern signals are im passenden Daily-Record belegt und zum owning Skill, task-manager oder system-health-check geroutet, wenn sie handlungsrelevant sind. Keine separate Feedback-Queue wird erzeugt.
  • Knowledge candidates are marked for later knowledge skills; this skill does not mix operative PersonalOS truth into knowledge-topic pages.
  • Write boundary: this skill may create daily/YYYY/YYYY-MM-DD/activity/<uuid>.md, daily/YYYY/YYYY-MM-DD/journal/<uuid>.md, assemble the matching Day Record, update atomic Action/Attention records via task-manager, update affected owner files, and update a skill/reference/template/script only when {{user_name}} explicitly asked for that change in the current session.
  • Capture boundary: when a session contains unresolved but materially valuable input that cannot yet be routed safely, this skill may create one atomic capture under inbox/captures/<uuid>.md from the registered profile and template. It does not mirror the full chat or create a general Idea Record.
  • Approval boundary: creating new durable owner records beyond the bounded Capture allowed above, changing identity/relationship/legal/tax/pricing/strategy/finance truth, deleting/moving existing owner files, resolving contradictions, or writing raw private/sensitive material requires explicit approval or is recorded as an unresolved point. The Capture exception never authorizes a new permanent domain owner.
  • Every new durable claim gets provenance through die atomare Activity/Journal-Evidenz, inline source, Source Map, provided source path, or explicit {{user_name}} statement.
  • All PersonalOS mutations follow [[system/contracts/core/personalos-mutation-contract]] and finish with pos-verify on the explicit changed-file list.
  • New and materially revised PersonalOS prose is written in German. Existing English records are not bulk-translated; when they are materially rewritten, consolidate the affected living truth in German. Source material retains its natural language. See 2026 08 07 sprache deutsch intern.

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.
