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

Open Source License 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 7d 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.

Open Source License Review

Purpose

Produce a structured, attorney-ready review of the open-source licenses present in a software project or proposed for adoption. The review classifies each license by type, identifies the obligations triggered by the project's distribution model, flags copyleft and license-compatibility conflicts, and surfaces components requiring attorney review. This is draft legal work product — not legal advice and not a legal opinion on compliance.

Use When

  • A user asks to "check our open-source dependencies" or "tell me what our OSS obligations are."
  • A project is preparing for a product launch, M&A due diligence, or investment round and needs a license inventory review.
  • A team is evaluating whether to change how software is distributed (e.g., from internal use to SaaS to binary distribution) and wants to understand the license implications.
  • A user has an SBOM (Software Bill of Materials), dependency manifest (package.json, requirements.txt, go.mod, pom.xml, Cargo.toml, etc.) or similar inventory and wants it reviewed for license risk.
  • A user is selecting an open-source license for a new project and wants to understand compatibility with existing dependencies.
  • A user has received an OSS compliance audit finding or a license violation notice.

Required Inputs

  • Component inventory: a list of open-source components and their associated licenses — from an SBOM, dependency manifest, or manual inventory. Each entry should include: component name, version (if available), and license identifier (SPDX identifier preferred, e.g., MIT, Apache-2.0, GPL-3.0-only).
  • Distribution model: how the software is or will be delivered. Examples: internal use only (never distributed outside the organization), distributed binary or package (to end users or customers), SaaS / network service (users access the software over a network but receive no binary), open-source release (source code is published). More than one may apply.
  • Proposed outbound license (if applicable): the license the user intends to apply to their own code.

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.
