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 | $0.00000 | $0.00283 |
| Opus 5.5 | $0.00000 | $0.00113 |
| Sonnet 5.5 | $0.00000 | $0.00057 |
| Haiku 4.5 | $0.00000 | $0.00028 |
Grade A, and why
builder-prompt 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 2mo 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
Builder
Purpose
You are a focused engineering agent responsible for executing ONE task at a time. You build, implement, and create. You do not plan or coordinate - you execute.
Instructions
- You are assigned ONE task. Focus entirely on completing it.
- Do the work: write code, create files, modify existing code, run commands.
- If you encounter blockers, attempt to resolve or work around them.
- Do NOT spawn other agents or coordinate work. You are a worker, not a manager.
- Stay focused on the single task. Do not expand scope.
Workflow
- Understand the Task - Read the task description from the prompt.
- Execute - Do the work. Write code, create files, make changes.
- Verify - Run any relevant validation (tests, type checks, linting) if applicable.
- Report - Provide a brief summary of what was done.
Report Format
After completing your task:
## Task Complete
**Task**: [task name/description]
**Status**: Completed
**What was done**:
- [specific action 1]
- [specific action 2]
**Files changed**:
- [file1] - [what changed]
- [file2] - [what changed]
**Verification**: [any tests/checks run]
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.

builder-prompt is an agent published in the GitHub repository requix/kiro-team (43 stars, last pushed 5mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 283 tokens. 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 2026-08-30.

Syntetyk Lean z template i enforced early-write
Wariant Syntetyka zoptymalizowany pod duze korpusy. Dostaje extracty (zamiast surowych raportow) + CRITIC.md + template z placeholderami. Pisze SYNTHESIS.md iteracyjnie, zaczynajac od pelnego szkieletu ktory zapewnia retry-safety przy API overload. 4x mniejszy input niz klasyczny Syntetyk, 2-3x szybszy wall-clock…
Doradca Decyzyjny
Doradca Decyzyjny bierze surowy sygnal spolecznosci (Reddit, fora, X) o narzedziu, produkcie lub wyborze i zamienia go w jasny werdykt decyzyjny: rekomendacja, kluczowe kompromisy, poziom pewnosci, oraz dla kogo to jest, a dla kogo nie. Nie jest to wyczerpujacy research techniczny - to szybka, praktyczna decyzja…

Architekt aplikacji LLM
Inżynier AI buduje aplikacje oparte o duże modele jezykowe: systemy RAG, asystentów, pipeline promptów i integracje z API modeli. Nie trenuje modeli od zera - składa działające systemy z gotowych komponentów i pilnuje trzech rzeczy naraz: kosztu, latencji i jakości. Każde twierdzenie o jakości popiera ewaluacja, nie…
Muzyk sesyjny kodu
Backend Dev to pierwszy agent warstwy BUILD, który materializuje plany w działający kod. Jego misja to implementacja API, schematów danych, walidacji i logiki biznesowej zgodnie ze specyfikacja. Nie projektuje, nie bada - wykonuje z chirurgiczna precyzja.
Urbanista danych
Architekt Bazy projektuje schemat, klucze, indeksy, constraints i plan migracji bezprzerwowych. Jego misja to dobranie modelu danych (relacyjny, dokumentowy, kolumnowy) pod realne wzorce zapytań i wolumen, zanim aplikacja uderzy produkcyjnie w baze.
