reading_line_movement

reading_line_movement is a skill for Claude Code, Codex from DanielTomaro13/sportsdata-agents. It costs 32 tokens per session (349 once invoked), scanned A, original, MIT.

A guide to interpreting changes in betting prices over time. It explains steam, when prices shorten; drift, when prices lengthen; and the closing price, the market price closest to the event's start.

In plain words
What is it for?
It is for reading line-movement data, comparing an entry price with the closing price, identifying market-wide moves, and finding books that have not yet adjusted.
Why use it?
It prevents a model from treating an old price as current value. It also makes the report account for opposing market signals, price changes, and gaps in the captured data.

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

reading_line_movement 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.

What it actually says

Reading line movement

query_line_movement gives the change-point series. What it means:

  • Steam (price shortening): money agrees with the side. If your model's edge was computed at the OLD price, it may already be consumed — recompute at the current price before calling it value. Fast multi-book steam usually means sharp/insider flow.
  • Drift (price lengthening): the market disagrees with your model. Drift into your pick raises the price (more apparent edge) while telling you informed money leans the other way — report BOTH facts, never just the bigger edge number.
  • The close is the benchmark: the most informed market state. Persistent edge vs the close (CLV) is the strongest evidence a process works (quant_concepts). When an event is settled, compare entry vs close in the report.
  • No movement = one first-sighting row, not "no data" — the price simply hasn't changed since capture began. Say which.
  • Cross-book divergence: one book lagging a market-wide move is the classic value window — flag the book and the lag explicitly when the series shows it.

Always state the capture cadence honestly: a 5-minute feed cannot see intra-minute steam, and gaps in the series are coverage gaps, not calm markets.

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.
