Write outbound email and external messages in Vamsee Achanta's voice — a subtle offer to help, never bold or rash claims. Load before drafting ANY email, LinkedIn/Collide reply, proposal note, or outreach sent under his name.
Save/publish analysis or computation results from ANY ecosystem repo to Hugging Face as a queryable, viewer-renderable dataset. Use when the user wants to "save results to hugging face", "publish dataset to HF", "hugging face data saving", "save analysis results", "hf dataset", "make results queryable", or "render via datasets-server API". Reshapes nested results into flat parquet tables, writes a dataset card with a viewer `configs:` block and provenance, applies license/public-vs-private routing, enforces a domain data-quality gate (faithful-to-source != correct), publishes to `aceengineer/<repo>-<projection>`, and verifies via the datasets-server API.
Clone, create, fork, configure, and manage GitHub repositories. Manage remotes, secrets, releases, and workflows. Works with gh CLI or falls back to git + GitHub REST API via curl.

# Stable release

# Latest development version

# With specific LM providers

pip install dspy[all] # All providers
import dspy
# Configure your language model
lm = dspy.Claude(model="claude-sonnet-4-6")
dspy.settings.configure(lm=lm)
# Define a signature (input → output)
class QA(dspy.Signature):
"""Answer questions with short factual answers."""
question = dspy.InputField()
answer = dspy.OutputField(desc="often between 1 and 5 words")
# Create a module
qa = dspy.Predict(QA)
# Use it
response = qa(question="What is the capital of France?")
print(response.answer) # "Paris"
import dspy
lm = dspy.Claude(model="claude-sonnet-4-6")
dspy.settings.configure(lm=lm)
# Use ChainOfThought for better reasoning
(dspy.Signature):
problem = dspy.InputField()
answer = dspy.OutputField(desc=)
cot = dspy.ChainOfThought(MathProblem)
response = cot(problem=)
(response.rationale)
(response.answer)
Signatures define the structure of your AI task (inputs → outputs):
# Inline signature (simple)
qa = dspy.Predict("question -> answer")
# Class signature (detailed)
class Summarize(dspy.Signature):
"""Summarize text into key points."""
text = dspy.InputField()
summary = dspy.OutputField(desc="bullet points, 3-5 items")
summarizer = dspy.ChainOfThought(Summarize)
When to use each:
Modules are reusable components that transform inputs to outputs:
Basic prediction module:
predictor = dspy.Predict("context, question -> answer")
result = predictor(context="Paris is the capital of France",
question="What is the capital?")
Generates reasoning steps before answering:
cot = dspy.ChainOfThought("question -> answer")
result = cot(question="Why is the sky blue?")
print(result.rationale) # Reasoning steps
print(result.answer) # Final answer
Agent-like reasoning with tools:
from dspy.predict import ReAct
class SearchQA(dspy.Signature):
"""Answer questions using search."""
question = dspy.InputField()
answer = dspy.OutputField()
def search_tool(query: str) -> str:
"""Search Wikipedia."""
# Your search implementation
return results
react = ReAct(SearchQA, tools=[search_tool])
result = react(question="When was Python created?")
Generates and executes code for reasoning:
pot = dspy.ProgramOfThought("question -> answer")
result = pot(question="What is 15% of 240?")
# Generates: answer = 240 * 0.15
Optimizers improve your modules automatically using training data:
Learns from examples:
from dspy.teleprompt import BootstrapFewShot
# Training data
trainset = [
dspy.Example(question="What is 2+2?", answer="4").with_inputs("question"),
dspy.Example(question="What is 3+5?", answer="8").with_inputs("question"),
]
# Define metric
def validate_answer(example, pred, trace=None):
return example.answer == pred.answer
# Optimize
optimizer = BootstrapFewShot(metric=validate_answer, max_bootstrapped_demos=3)
optimized_qa = optimizer.compile(qa, trainset=trainset)
# Now optimized_qa performs better!
Iteratively improves prompts:
from dspy.teleprompt import MIPRO
optimizer = MIPRO(
metric=validate_answer,
num_candidates=10,
init_temperature=1.0
)
optimized_cot = optimizer.compile(
cot,
trainset=trainset,
num_trials=100
)
Creates datasets for model fine-tuning:
from dspy.teleprompt import BootstrapFinetune
optimizer = BootstrapFinetune(metric=validate_answer)
optimized_module = optimizer.compile(qa, trainset=trainset)
# Exports training data for fine-tuning
