This is tusharagg1/aifolimizer's own configuration. It tells Claude Code how to work on aifolimizer itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything aifolimizer configures →

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

stock-compare 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 9d 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 — 110 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Stock Compare (Head-to-Head)

Stage 0 - Decision Memory (load BEFORE forming any verdict)

Before fetching market data, load prior decisions on each ticker (A and B) so the verdict stays consistent across sessions:

  • mcp__aifolimizer__get_ticker_decision_history with ticker=A then ticker=B (max_decisions=5) - prior actions, outcomes, reflections
  • mcp__aifolimizer__get_ticker_reflection with symbol=A / symbol=B (n=3) - prior recs + realized alpha
  • mcp__aifolimizer__get_cross_ticker_lessons with max_lessons=3 - portfolio-level win/loss patterns

Reconciliation rule: if a prior decision exists and your new read flips it, state explicitly WHY it changed (new data / catalyst / price move). Never silently contradict a logged decision - that drift is exactly what this prevents.

How to run

  1. Call mcp__aifolimizer__get_profile - account types, capital, tax context. Frame placement recommendation at end (TFSA vs RRSP vs Non-Reg)
  2. Identify two tickers from user query (Ticker A, Ticker B). If user names only one and asks "vs sector leader", pick obvious peer and state choice explicitly
  3. Call mcp__aifolimizer__get_portfolio - flag which tickers user already holds, with current weight and cost basis
  4. Call mcp__aifolimizer__get_fundamentals with symbols=[A, B] in one call - P/E, EPS, dividend yield, payout, market cap, analyst target, beta
  5. Call mcp__aifolimizer__get_technicals with symbols=[A, B] in one call - SMA20/50/200, RSI, MACD, Bollinger Bands, trend, Minervini stage + score, 52-week context
  6. Call mcp__aifolimizer__get_news_headlines for each ticker - recent catalyst differential
  7. WebSearch only for: sector peer multiples, recent analyst upgrade/downgrade asymmetry, or gaps in MCP response

Investor profile

  • Canadian retail investor
  • Time horizons: short-term trading + long-term (10yr+) holding
  • Strategy lens: confirm with user (growth / income / value); default to growth if unstated
  • Account types and capital: always read from get_profile - never hardcode

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.
