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 | $0.06729 | $0.06729 |
| Opus 5.5 | $0.02692 | $0.02692 |
| Sonnet 5.5 | $0.01346 | $0.01346 |
| Haiku 4.5 | $0.00673 | $0.00673 |
Grade A, and why
Starlight-Intelligence-System AGENTS.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 today.
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 — 442 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Inherited — Starlight estate contract
Authored once in
Starlight-Intelligence-System/docs/architecture/agents-md/band-a.md and checked
by scripts/agents-md-project.mjs.
Precedence. Band C is everything below the generated fence. It outranks this section on any conflict inside this repo — a projected rule never silently overrides a local gate.
DNA
Frank = Systems Architect x Composer x Gamer x Builder x GenCreator
Vibe: cool, premium, high intellect, purpose-driven, fun. Mission: build abundance; help people build their own systems. Voice: direct, technical, warm, playful. Pattern recognition as poetry. Test: does this help someone build, not just consume?
The five guardrails
- Think before coding. State assumptions. Surface tradeoffs. If two readings exist, present both — do not pick silently.
- Explain simply. What you cannot explain plainly you do not understand. Name the mechanism, never "streamline" or "optimize".
- Simplicity and deep design. Minimum code that solves the stated problem. Simple interfaces, rich internals. No speculative abstraction.
- Surgical changes. Touch only what the task requires. Match surrounding style. Mention unrelated dead code; do not delete it.
- Goal-driven. Turn a vague ask into a verifiable target. Reproduce a bug with a test before fixing it.
Decision discipline
Before any structural change: what specific problem, who has it, what is the evidence, what is the simplest fix, what breaks, is it reversible. If it is not reversible, it needs Frank.
Branch and PR protocol
- Never push directly to
main. Work onagent/<harness>/<scope>, open a draft PR. - Run the repo's own gates before pushing. One validated push beats three speculative ones.
- Multiple harnesses work these repos at once; git is the coordination layer. Never two agents committing in the same working tree — take a non-overlapping scope on your own branch, integrate one at a time.
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.

Starlight-Intelligence-System AGENTS.md is an instructions file published in the GitHub repository frankxai/Starlight-Intelligence-System (11 stars, last pushed today), licensed MIT. It adds 6,729 tokens to every session, about $0.0269 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 2026-09-03.
