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

Competitor Collaboration Review 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 11d 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.

Competitor Collaboration Review

Purpose

Review a proposed or existing collaboration between actual or potential competitors — joint venture, R&D pact, joint purchasing, joint marketing or distribution, benchmarking, standard-setting, joint bidding, settlement collaboration — and organize what an antitrust attorney needs to assess it: verbatim hardcore-restraint flags, an information-flow matrix, ancillarity and spillover questions, and per-jurisdiction safe-harbor questions. The skill flags and asks; it never applies a safe harbor, resolves an ancillarity question, or approves the collaboration. The output is draft legal work product for attorney review only.

Use When

  • A business team proposes a JV, co-development, or co-marketing arrangement with a competitor and counsel needs the draft agreement flagged before signing.
  • Two competitors want to bid jointly on a tender or pool purchasing volume, and the arrangement needs hardcore-restraint and ancillarity screening.
  • A standard-setting or industry working-group arrangement raises F/RAND, patent-disclosure, membership, or coordination questions.
  • A draft collaboration agreement contains non-competes, exclusivity, or data-sharing annexes whose reach beyond the stated venture purpose needs to be mapped.
  • Counsel asks what competitively sensitive information would flow between the parties under a proposed collaboration, and under what controls.
  • An existing collaboration is being renewed or expanded and its restraints and information flows need a fresh review.

Required Inputs

  • Jurisdiction(s) of competitive effect — every country and, where relevant, state/province where the collaboration would operate or have effects, or [verify jurisdiction].
  • Collaboration purpose and structure — joint venture, NDA-only information exchange, R&D pact, joint purchasing, joint marketing or distribution, benchmarking, standard-setting, joint bidding, settlement-related collaboration, or other. Mark unknowns unknown/not found/not provided/ambiguous.
  • Parties' competitive posture — for each pair of parties on each product/geographic market: actual competitors, potential competitors, or unrelated. Multi-product collaborations get one row per market.
  • Information exchange contemplated — categories of data (pricing, costs, customers, output, capacity, wages/hiring, future plans, R&D), granularity, age, frequency, aggregation, recipients, controls.
  • Governance and independence — whether each party retains independent decision-making on price, output, customers, R&D direction, hiring, and any other competitively significant conduct outside the collaboration.
  • Restrictions on competitive conduct — non-compete, exclusivity, scope limits, customer or territory carveouts, hardcore restraint candidates (price, output, allocation, boycott).
  • Duration, termination, and unwind — term, termination triggers, post-termination obligations, information return/destruction.
  • Safeguards — antitrust counsel oversight, clean teams, training, audits, antitrust statement at meetings.
  • Business rationale and pro-competitive justifications — efficiencies the user is relying on; documents supporting them.
  • Documents and source anchors — collaboration agreement(s), NDA, term sheet, board materials, business case, communications. Every extracted fact cites the document and section.
