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 | $0.00125 | $0.03508 |
| Opus 5 | $0.00063 | $0.01754 |
| Sonnet 5 | $0.00025 | $0.00702 |
| Haiku 4.5 | $0.00013 | $0.00351 |
Grade A, and why
flyte-sdk-types scanned grade A with 1 finding 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 2d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Ground unfamiliar APIs in real examples. When unsure of a current Flyte 2 API, or for a pattern not shown below, and the flyte-docs search tools are available, search them first — by exact symbol (TaskEnvironment, flyte.io.File, map_task), since matching is literal substring, not semantic — then adapt a real example rather than inventing one, and cite the file or section you pulled it from. (Flyte 2 is not flytekit; priors are often wrong.)
Type System Overview
Flyte 2 uses Python type hints for serialization. Every task input/output must have a type annotation. Flyte's type transformer system handles conversion between Python types and remote storage (S3, GCS, etc.).

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.

flyte-sdk-types is a skill published in the GitHub repository flyteorg/flyte-agent-plugins (2 stars, last pushed 5d ago), licensed Apache-2.0. It adds 125 tokens to every session and 3,508 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
