Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.01898 | $0.01898 |
| Opus 5 | $0.00949 | $0.00949 |
| Sonnet 5 | $0.00380 | $0.00380 |
| Haiku 4.5 | $0.00190 | $0.00190 |
Grade A, and why
Flyan 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 4d 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 — 197 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
Notes for AI agents working in this repo. The file follows the agents.md convention so Claude Code, Cursor, Aider, and similar tools pick it up automatically.
What Flyan is
An unofficial Python SDK for Ryanair's undocumented public flight-search API, plus an optional MCP server that exposes the same surface to LLM agents in natural language.
There is no API contract from Ryanair. Behaviour is reverse-engineered from
poking the live endpoints; the source of truth for endpoint quirks is
docs/internal-api-spec.md. Update that doc whenever an endpoint's
behaviour, params, or response shape changes.
Layout
flyan/
ryanair.py # Sync client (RyanAir). Domain-friendly methods that
# build URLs, delegate to transport, and call parsers.
async_client.py # Async mirror (AsyncRyanAir). Keep in lockstep with
# ryanair.py — every public method on one should exist
# on the other with the same signature.
transport.py # HTTP seam. Owns httpx, retries, UA rotation, cookie
# warm-up, Accept-Encoding, and nextPage pagination.
# Adapters: RyanairTransport, AsyncRyanairTransport,
# CachingTransport.
wire.py # Translation between public models and Ryanair wire
# format. Field-name quirks (departureAirportIataCode,
# lowercase iso2, currency-as-query-param) live HERE
# and nowhere else.
misc.py # Public Pydantic models (Flight, FlightSearchParams,
# Network, NetworkAirport, DestinationFare, ...).
# No wire knowledge.
tracker.py # Local PriceTracker for price-history analysis.
mcp_server.py # MCP server exposing curated tools to agents.
currencies.json # Static lookup of supported ISO 4217 currencies.
docs/
internal-api-spec.md # Living notes on the undocumented Ryanair API.
# READ THIS before adding or modifying an endpoint.
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.

Flyan AGENTS.md is an instructions file published in the GitHub repository victorlane/Flyan (1 stars, last pushed 3d ago), licensed MIT. It adds 1,898 tokens to every session, about $0.0095 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.
