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

PeerScan 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 6d 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.

Examples

Example 1: Scan a developer's PR history

User: "Scan @johndoe's PRs in acme/backend for the last 6 months"
→ Fetches all PRs via gh CLI
→ Analyzes volume, themes, quality signals
→ Generates structured report
→ Saves to Obsidian vault

Example 2: Client team assessment

User: "Assess the engineering activity for the 3 senior devs at client X"
→ Launches parallel PeerScan agents per developer
→ Generates comparison report
→ Identifies strengths and growth areas

What ships with it

Changes

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.
