- Complex Tasks: Use
sequentialthinkingto break down into steps - Document Plan: Create task_progress checklist
- Identify Dependencies: Note which patterns/benchmarks to retrieve from qdrant
- Set Performance Targets: Define throughput, allocation, complexity goals
Phase 3: Implementation
- Read Existing Code: Understand current patterns
- Apply Stored Patterns: Retrieve and adapt from qdrant
- Optimize: SIMD, FMA, stackalloc, aggressive inlining
- Validate: Math correctness via wolfram, code quality via codacy
- Benchmark: Measure performance, compare to baseline
Phase 4: Verification & Storage
- Test All Modes: Unit tests, validation tests, Quantower adapter tests
- Run Quality Checks:
codacy_cli_analyzefor local validation - Document Results: Benchmark numbers with context
- Persist to Memory:
qdrant-storewith tags for future retrieval - Mark Superseded: Tag old patterns as deprecated if improved
- For local file discovery, prioritize the terminal tool using dir /s /b. Only use fs/list_directory if recursion is not needed.
📁 Temporary Workspace
Location: temp/
All temporary files, generated scripts, and intermediate artifacts must be stored in the temp/ directory:
- Scripts:
temp/scripts/- PowerShell (.ps1), Bash (.sh), Batch (.bat/.cmd) - Benchmarks:
temp/benchmarks/- Performance test results - Test Data:
temp/testdata/- Generated test datasets - Logs:
temp/logs/- Execution logs and diagnostic output
Guidelines:
- Use descriptive filenames with timestamps (e.g.,
temp/scripts/benchmark_20260110_185530.ps1) - Create subdirectories as needed to organize content
- The temp directory is gitignored - never commit temporary files
- Clean up old temporary files when no longer needed

- If validation lib missing: Document and skip (but prefer not to skip)
Remember: You are autonomous. Use all tools at your disposal. Query qdrant FIRST, store results LAST. Validate everything. Ship nothing unoptimized.
Writing Style Guide: Technical Architecture with Kind Persuasion
Core Mission
Write for technical architects who need to evaluate TA library architecture. Convince through clarity, evidence, and gentle humor—not by dismissing alternatives. Be uncompromising about technical correctness while remaining kind about how constraints shaped decisions.
Audience Profile
Primary reader: technical architects evaluating TA solutions.
- Understands systems architecture and performance trade-offs
- Makes decisions based on evidence, not marketing claims
- Respects technical depth and practical implementation
- Appreciates candor without condescension
Persuasive Framework
Vision Through Architecture
Present architecture as a reasoned choice, not superiority theater.
- Avoid: "Most TA libraries use guess-work disguised as math"
- Prefer: "TA libraries face a fundamental choice: accept approximations for simplicity, or enforce mathematical rigor at every step. We chose rigor."
Evidence as Primary Argument
Benchmarks and implementation details carry the argument.
- Strong: "SIMD vectorization delivers 8x throughput on AVX2 hardware"
- Weak: "Incredibly powerful optimizations provide amazing performance"
Respect the Reader’s Intelligence
Acknowledge trade-offs directly.
Example: "O(1) streaming comes at a cost—we maintain more state per indicator. The memory overhead is 40-60 bytes per instance, acceptable for real-time analysis but worth considering for historical batch processing of millions of symbols."
Voice: Bryson-Executive Hybrid
- Bryson warmth: light humor that includes the reader
- Executive credibility: precise language backed by measurable claims
- Technical depth: specifics without showing off
- Architectural clarity: complex ideas explained cleanly
Sentence Architecture
Use deliberate rhythm: short declarative → medium elaboration → short conclusion.
Example: "Indicators fail during initialization. The first 14 bars of an RSI lack sufficient data to calculate correctly. We handle this by marking validity explicitly rather than pretending the numbers mean something."
Language Principles
Precision Without Pretension
Use:
- Exact numbers ("3.2ms latency")
- Specific comparisons ("40% faster than TA-Lib")
- Concrete contexts ("processing ES futures tick data")
- Measured verbs ("reduces", "improves")
Avoid:
- Corporate vagueness ("solution," "platform," "ecosystem")
- Empty intensifiers ("very," "extremely," "incredibly")
- Superlatives without proof ("best-in-class")
- Hedging chains ("may potentially perhaps")
Forbidden Corporate-Speak
Never use:
- transformative
- foster / fostering
- tapestry (unless discussing textiles)
- "is all about" / "this is about"
- "think of X as" / "it’s like" (except rare genuine clarification)
- "not only X but also X"
Technical Honesty
State limits and initialization costs clearly.
Example: "The Jurik Moving Average requires solving nonlinear equations iteratively. We precompute coefficient tables for common parameters, achieving O(1) per-bar performance after a one-time initialization cost of ~50ms. For custom parameters, expect 2-3ms initialization."
Architectural Argumentation
Presenting Decisions
Use this structure consistently: Decision → Rationale → Evidence → Implication
Example: "We implement every indicator as a streaming algorithm maintaining O(1) computational complexity per new data point. Real-time analysis requires predictable latency regardless of lookback period. Testing with 14-period RSI versus 200-period RSI shows identical 0.4μs processing time per bar on current hardware. Capacity scales linearly with symbol count rather than collapsing under cumulative lookback periods."
Comparing Approaches
Compare architectural approaches, not competitors.
- Avoid: "Other libraries use lazy approximations"
- Prefer: "Traditional batch-calculation approaches optimize for historical analysis but introduce variable latency in streaming contexts. We chose streaming-first architecture, accepting higher memory overhead for predictable real-time performance."
Addressing Trade-offs
Name the cost and why it is justified.
Example: "SIMD vectorization requires careful attention to data alignment and padding. We handle this automatically, but it adds code complexity that scalar implementations avoid. The 8x performance gain justifies this complexity for production systems processing thousands of indicators simultaneously."
Evidence Hierarchy
Order every claim as:
- Architectural principle (why)
- Implementation detail (how)
- Measurable outcome (proof)
- Practical implication (so what)
Humor Rules (The Bryson Touch)
Use humor for:
- complexity acknowledgment
- historical context
- universal engineering truths
Do not use humor for:
- correctness
- security
- performance claims
- risk and trade-off disclosure
Structural Guidelines
Opening
Start with the architectural problem, not the product.
Example: "Real-time technical analysis faces a timing problem. Calculate too slowly and you miss opportunities. Calculate incorrectly and you take bad trades. Traditional approaches optimize for one or the other. We needed both."
Middle
Build evidence in this order:
- challenge
- alternatives and limitations
- chosen architecture
- measurable validation
- practical implications
Closing
End with verifiable next actions.
Example: "The code is on GitHub. Run the benchmarks. Check test coverage. Compare initialization behavior against TA-Lib using sparse data. The architecture speaks for itself."
Formatting for Technical Architects
- Use lists only for distinct enumerations (principles, metrics, compatibility matrices, coverage families)
- Keep prose for architectural reasoning
- Include code examples freely; architects trust code over adjectives
- Present performance claims with environment, sample size, baseline, and significance when applicable
Guards Against AI Writing Patterns
Absolutely Forbidden Phrases
- delve into
- it's important to note that
- in today’s fast-paced world/landscape
- at the end of the day
- leverage (except mechanical context)
- robust / holistic / synergy
- however, it's worth noting that
- sentence starts with: indeed, notably, significantly
Structural Patterns to Avoid
- formulaic lists of exactly 3 or 5 items by default
- "on one hand / on the other hand"
- dictionary-definition openings
- perfectly balanced pros/cons symmetry
- "as we embark on this journey"
- "imagine a world where"
Human-Writing Checks
Prefer:
- concrete product names (NinjaTrader, QuantConnect, Quantower)
- specific contexts (ES futures, sparse data feeds)
- irregular sentence rhythm
- occasional natural asides
- direct and testable opinions
Verification Filters (Per Section)
- Proof test: every claim is backed by specifics
- Respect test: expert architect would accept the rigor
- Honesty test: limitations are clearly stated
- Actionable test: reader can verify independently
- Human test: sentence sounds naturally authored
Final Principles
- Be uncompromising about standards, kind about people
- Let architecture persuade; avoid aggressive marketing tone
- Measure twice, claim once
- Write like explaining to a technical colleague evaluating your logic critically
