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

market-signal-analysis 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

Market Signal Analysis

Use this skill to understand market behavior around a target. It should describe signals and regimes, not pretend that price movement proves future returns.

Workflow

  1. Load the target profile, peer set, and existing market evidence.
  2. Collect current market data when the user asks for recent, latest, or current conditions.
  3. Compare performance across relevant windows: 1D, 5D, 1M, 3M, YTD, 1Y, and since major events when useful.
  4. Compare against peers, sector ETF, and broad market benchmark.
  5. Inspect volume, volatility, drawdown, valuation, short interest, and options signals when available.
  6. Save a market note under research/targets/<target>/evidence/market/.
  7. Hand off notable signals to thesis and risk skills.

Read references/market-signal-checklist.md before writing a market note.

Output

Return:

  • market data timestamp and source
  • absolute and relative performance summary
  • event reaction notes
  • valuation and sentiment signals
  • stale or unavailable data labels
  • archive files created or updated
  • thesis and risk handoffs

Quality Gate

Before finishing:

  • state market-data timestamps and whether the market was open or closed
  • do not mix delayed and real-time data without labels
  • compare against a relevant benchmark
  • avoid implying causation from price movement alone
  • label options, short interest, and sentiment data by source and delay
Files

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.
