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

waiver-scan 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 12d 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.

How it starts

The opening of the file, as written. The whole thing — 83 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Waiver Scan: Fit Over Fame

Rank available players against this roster's holes, not a generic top-adds list. A backup RB one injury from a workload is worth more to a team with a thin RB room than the "consensus #1 add" WR is to a team already starting three good ones.

Step 1: Load context

Read leagues.md from the project root first — the fields that matter here are scoring, starting slots, waiver system, playoff weeks, and any weekly acquisition cap. If the file is missing or those fields are blank, ask for them and suggest running fantasy-league-setup:league-config. If more than one league is defined, use the one marked (default).

An acquisition cap changes everything downstream: where adds are limited, each claim must clear a much higher bar and churning streamers is off the table.

Pin time-sensitive recommendations to an as-of timestamp. When a player's value depends on an injury, benching, suspension, or activation, cite both the official status input and a second credible source before treating the role change as settled. If the evidence is incomplete, keep the ranking provisional and say the default action is to wait rather than force a move.

Step 2: Get the two inputs

  1. The user's roster — read from their platform if browser automation is available, otherwise pasted. Include the current week and any injury designations.
  2. The available player pool — read the platform's free-agent list directly, or ask for a paste. Do not rely on one sort alone. Pull a broader sample: the best available players at each relevant position, plus views sorted by rostered%, recent usage or targets/snaps, projected points, and recent adds/drops if the platform shows them. A good fallback is 8-12 names per relevant position from multiple sorts, not just the global top 30 by rostered% or recent scoring. Without a pool, describe the profile to target ("your hole is RB depth — target any back whose starter just landed on IR") and ask for the list to name names.

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.
