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 5.1 | $0.00050 | $0.01287 |
| Opus 5 | $0.00025 | $0.00643 |
| Sonnet 5 | $0.00010 | $0.00257 |
| Haiku 4.5 | $0.00005 | $0.00129 |
Grade A, and why
python-scala-syntax-mapping 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 9d 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 python-scala-syntax-mapping — 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.

Python to Scala Syntax Mapping
Variable Declarations
| Python | Scala |
|---|---|
x = 5 |
val x = 5 (immutable) or var x = 5 (mutable) |
x: int = 5 |
val x: Int = 5 |
x, y = 1, 2 |
val (x, y) = (1, 2) |
Prefer val over var unless mutation is required.
Type Mappings
| Python | Scala |
|---|---|
int |
Int |
float |
Double |
str |
String |
bool |
Boolean |
None |
None (of type Option) or null |
list[T] |
List[T] or Seq[T] |
dict[K, V] |
Map[K, V] |
set[T] |
Set[T] |
tuple[A, B] |
(A, B) or Tuple2[A, B] |
Optional[T] |
Option[T] |
Control Flow
Conditionals
# Python
if x > 0:
result = "positive"
elif x < 0:
result = "negative"
else:
result = "zero"
// Scala - if is an expression
val result = if (x > 0) "positive"
else if (x < 0) "negative"
else "zero"
Loops
# Python for loop
for i in range(10):
print(i)
for item in items:
process(item)
for i, item in enumerate(items):
print(f"{i}: {item}")
// Scala equivalents
for (i <- 0 until 10) println(i)
for (item <- items) process(item)
for ((item, i) <- items.zipWithIndex) println(s"$i: $item")
While loops
# Python
while condition:
do_something()
// Scala
while (condition) {
doSomething()
}
Comprehensions
# Python list comprehension
squares = [x ** 2 for x in range(10)]
evens = [x for x in numbers if x % 2 == 0]
pairs = [(x, y) for x in xs for y in ys]
// Scala for-comprehensions or map/filter
val squares = (0 until 10).map(x => x * x).toList
val evens = numbers.filter(_ % 2 == 0)
val pairs = for { x <- xs; y <- ys } yield (x, y)
Functions
# Python
def add(a: int, b: int) -> int:
return a + b
# Lambda
square = lambda x: x ** 2
# Default arguments
def greet(name: str, greeting: str = "Hello") -> str:
return f"{greeting}, {name}!"
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.

python-scala-syntax-mapping is a skill published in the GitHub repository xuansenpa1/skillrevise (56 stars, last pushed 7d ago), licensed MIT. It adds 50 tokens to every session and 1,287 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to python-scala-syntax-mapping, differing in 0 lines, and is treated as a copy.
