contextops 0.2.0

Deterministic context linter for LLM applications — analyze, score, and optimize your LLM context payloads.

ContextOps

The deterministic context linter for LLM applications.

ContextOps analyzes the context fed into your LLM and tells you what's broken — redundant chunks, wasted tokens, structural imbalance — with a deterministic 0–100 score and actionable fixes.

Think of it as ESLint for your LLM prompts.

---

Why ContextOps?

Most LLM applications blindly stuff context into the prompt window. This leads to:

• 💸 Wasted spend — paying for redundant tokens that don't improve output
• 🔁 Silent regressions — a "small RAG change" floods the context with duplicates
• 🏗️ Structural drift — retrieval chunks slowly dominate the entire prompt
• 🎯 No visibility — teams have no way to measure context quality in CI

ContextOps gives you that visibility. It runs in your CI pipeline, scores every context payload, and fails the build if quality degrades.

Quick Start

pip install contextops

See it in action

# Run the built-in demo — instant "wow moment"
contextops demo

Analyze your own context

# Full analysis with rich terminal output
contextops inspect context.json

# CI mode: fail if score drops below threshold
contextops check context.json --min-score 70

# Compare two snapshots for regressions
contextops diff before.json after.json

# JSON output for dashboards and automation
contextops inspect context.json --json-output

Python API

from contextops.api.inspect import inspect_context

result = inspect_context({
    "system": "You are a helpful assistant.",
    "chunks": [
        {"content": "Refund policy: 30 days...", "source": "docs/refund.md"},
        {"content": "Refund policy: within 30 days...", "source": "docs/refund.md"},
    ],
    "memory": ["User asked about refunds before."],
})

print(f"Score: {result.score}/100")
print(f"Wasted tokens: {result.token_breakdown.wasted_tokens}")
for rec in result.recommendations:
    print(f"  → {rec.fix}")

What It Measures

ContextOps computes a 0–100 Context Score from four independent penalty dimensions:

Dimension	What It Detects	Max Penalty
Redundancy	Duplicate / near-duplicate chunks (N-gram + Jaccard)	30 pts
Density	Wasted tokens from structural bloat	30 pts
Structure	Imbalanced type distribution (e.g., retrieval > 70%)	20 pts
Concentration	Source dominance or highly imbalanced chunk distribution	20 pts

Context Score = 100 - (Redundancy + Density + Structure + Concentration)

Every penalty maps to a specific finding with token savings and an actionable fix.

CI / CD Integration

GitHub Actions

name: Context Quality Gate

on: [pull_request]

jobs:
  context-check:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-python@v5
        with:
          python-version: "3.12"

      - run: pip install contextops

      - name: Check context quality
        run: contextops check prompts/context.json --min-score 75

Exit Codes

Code	Meaning
0	Score meets threshold — build passes
1	Score below threshold — build fails

Regression Detection

# Save a baseline
contextops inspect prompts/v1.json --json-output > baseline.json

# After changes, compare
contextops diff baseline.json prompts/v2.json

Context File Format

ContextOps accepts a JSON file with any combination of these keys:

{
    "system": "Your system prompt here",
    "messages": [
        {"role": "user", "content": "User question"}
    ],
    "chunks": [
        {"content": "Retrieved chunk text", "source": "docs/page.md"}
    ],
    "memory": [
        "Previous conversation context"
    ],
    "tools": [
        {"name": "search_api", "output": "Tool response text"}
    ]
}

It also accepts raw OpenAI message lists:

[
    {"role": "system", "content": "You are helpful."},
    {"role": "user", "content": "What is the refund policy?"}
]

Design Principles

1. Deterministic — Same input → same output. Always. No randomness, no embeddings, no LLM calls.
2. Explainable — Every penalty maps to a real issue with a token count and a fix.
3. CI-native — Designed for pipelines first. Exit codes, JSON output, threshold gating.
4. Zero network — Runs entirely offline. No API keys, no external services.

---

Stability Contract

ContextOps ships with a formal Stability Contract that guarantees:

• Scoring determinism — same input always produces the same score
• Schema stability — JSON output fields never change within a major version
• Performance bounds — sub-second for payloads up to 50,000 tokens
• Semantic versioning — scoring formula changes require a major version bump

This contract exists so teams can trust ContextOps in production CI pipelines.
