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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00033 | $0.00730 |
| Opus 5 | $0.00016 | $0.00365 |
| Sonnet 5 | $0.00007 | $0.00146 |
| Haiku 4.5 | $0.00003 | $0.00073 |
Grade A, and why
execution 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 — 90 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Scope Constraint
- Execution files:
src/alpacalyzer/execution/ - Tests:
tests/test_execution*.py
Architecture
ExecutionEngine
├── SignalQueue — priority queue of pending signals
├── PositionTracker — tracks open positions with P&L
├── CooldownManager — rate limiting per ticker
└── OrderManager — bracket orders (entry + stop + target)
Key invariant
Exits are ALWAYS processed before entries. This protects capital.
Steps
1. Study the execution cycle
Read src/alpacalyzer/execution/engine.py, focusing on run_cycle():
- Sync positions from broker
- Process exits (capital protection first)
- Process entries (new positions)
- Update cooldowns
- Emit summary event
2. Understand each component
| Component | File | Key class |
|---|---|---|
| Engine | src/alpacalyzer/execution/engine.py |
ExecutionEngine, ExecutionConfig |
| Signals | src/alpacalyzer/execution/signal_queue.py |
SignalQueue, PendingSignal |
| Positions | src/alpacalyzer/execution/position_tracker.py |
PositionTracker, TrackedPosition |
| Cooldowns | src/alpacalyzer/execution/cooldown.py |
CooldownManager |
| Orders | src/alpacalyzer/execution/order_manager.py |
OrderManager, OrderParams |
| State | src/alpacalyzer/execution/state.py |
Shared state models |
3. Make changes
Read the specific component file before modifying. Key patterns:

4. Write tests
Follow patterns in existing execution tests. Always:
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.

execution is a skill published in the GitHub repository kimrejstrom/alpacalyzer-algo-trader (2 stars, last pushed 3mo ago), licensed MIT. It adds 33 tokens to every session and 730 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
