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

investigation-timeline-builder 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 8d 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.

Investigation Timeline Builder

What This Skill Does

Builds a structured, annotated chronological timeline from raw notes, documents, or source interview summaries, formatted for both internal reporting use and potential publication as a graphic.

When To Use This Skill

  • You have accumulated research from multiple sources and need to impose chronological order on a complex sequence of events
  • You are preparing a narrative investigation and need to see the full arc of events before structuring the story
  • You want a timeline that flags gaps, contested dates, and unverified entries so editors can see what still needs reporting
  • You are planning a published timeline graphic and need a draft with source attributions for each entry

What You Need To Provide

Required: Raw notes, document excerpts, or bullet-point summaries of events in any order; the investigation's subject (person, institution, or incident) Optional: Known key dates you want anchored; the intended output use (internal working document vs. publishable graphic); any disputed or uncertain dates you want flagged; sources for specific events (document names, interviewee names)

How the Assistant Approaches This

  1. Extracts all dateable events from the raw input and sorts them chronologically, noting where only approximate dates are available
  2. For each entry, records the event, the source or document it comes from, and a verification status (confirmed, single-source, or unverified)
  3. Identifies structural gaps in the timeline — periods of unexplained silence, missing transitions between events, or logical breaks that suggest something happened but is not yet documented
  4. Produces two versions if requested: a detailed internal version with source notes and verification flags, and a clean publishable version suitable for graphic design handoff
  5. After the timeline, provides a "Next Step" note: identifying the highest-priority reporting gap to close first, whether to run foia-request-writer to obtain official records for an unverified entry, and what is needed before the publishable version can be released
