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 | $0.00009 | $0.00254 |
| Opus 5.5 | $0.00004 | $0.00102 |
| Sonnet 5.5 | $0.00002 | $0.00051 |
| Haiku 4.5 | $0.00001 | $0.00025 |
Grade A, and why
add-adapter-method 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.
This is a copy
100% identical to add-adapter-method — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
Add method $ARGUMENTS to both V2 and V3 adapters.
Steps
- Add abstract method to
adapters/base.py:
@abstractmethod
def method_name(self, param: str) -> dict[str, Any]:
pass
- Implement in
adapters/airflow_v2.py:
def method_name(self, param: str) -> dict[str, Any]:
return self._call(f"endpoint/{param}")
- Implement in
adapters/airflow_v3.py:
def method_name(self, param: str) -> dict[str, Any]:
return self._call(f"endpoint/{param}")
Version Differences
| Feature | Airflow 2.x | Airflow 3.x |
|---|---|---|
| API path | /api/v1 |
/api/v2 |
| Assets | datasets |

| DAG runs | execution_date |
logical_date |
Normalize V2 responses to match V3 field names when they differ.
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.

defer
Defer a task to the cleanest grid-energy window inside a deadline. Invoke this command automatically whenever the user signals a task is not time-critical — phrases like "do this later", "by tomorrow", "tonight", "overnight", "by EOD", "sometime this week", "when you have a moment", "remind me to", "queue this up"…
