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 | $0.01394 | $0.01394 |
| Opus 5.5 | $0.00558 | $0.00558 |
| Sonnet 5.5 | $0.00279 | $0.00279 |
| Haiku 4.5 | $0.00139 | $0.00139 |
Grade A, and why
post-kit architecture.md 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 16d 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 — 143 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Project Architecture — Single Responsibility at Every Level
How top-tier open source projects stay maintainable: every piece has one job, clear boundaries, and obvious names.
The Principle
Single responsibility applies at every level:
- System level: each layer has one job (Tauri=shell, FastAPI=logic, Frontend=display)
- Module level: each module owns one feature completely
- File level: each file has one purpose
- Function level: each function does one thing
- Line level: each line is readable without context
If you can't explain it in one sentence, it's too complex. Split it.
System Architecture

└─────────────────────┬───────────────────────────────┘

Module Rules
Every module follows this structure:
modules/<name>/
├── router.py # HTTP in/out. Thin. Calls service.
├── service.py # Logic. Thick. The brain.
└── models.py # Pydantic schemas. The contract.
| File | Allowed to import | NOT allowed to import |
|---|---|---|
| router.py | FastAPI, own service, own models | Other modules, database directly |
| service.py | core/bridge, core/database, core/events | FastAPI, other modules |
| models.py | Pydantic, stdlib | Anything else |
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.

post-kit architecture.md is an instructions file published in the GitHub repository Huzaifa-ali/post-kit (4 stars, last pushed 17d ago), licensed MIT. It adds 1,394 tokens to every session, about $0.0056 per session on Opus 5.5. 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 2026-10-11.
