What's New in v2.2.0 — Telemetry Completeness & Crash Safety

This release adds crash-safe JSONL streaming, failure-path telemetry for all 21 tools, encrypted error fields, and automatic log retention policies. All telemetry events are now captured with proper error handling and flushed incrementally per tool call for maximum durability.

What's New in v2.1.1 — Metadata Sync

This patch release refreshes public packaging metadata so PyPI and Marketplace copy match the current 22-core-tool product framing.

Previous: v2.1.0 — Expanded Language Matrix

[20260310_DOCS] The source-of-truth tier files currently advertise 13 languages on the tier-configured analyze_code and unified_sink_detect surfaces.

[20260306_DOCS] Core parsing, extraction, and analysis surfaces span the full language set. Graph-oriented MCP tools such as get_call_graph, get_graph_neighborhood, and get_cross_file_dependencies remain Python-first today, with an initial JavaScript/TypeScript function-node parity slice now available in get_call_graph and get_graph_neighborhood, plus partial awareness in some shared JS/TS/Java paths.

Language	Extensions	Highlights
Python	.py	Full AST + PDG + symbolic execution
JavaScript	.js, .jsx	AST, extraction, partial graph/dependency awareness
TypeScript	.ts, .tsx	Full type analysis, React components
Java	.java	AST parsing and analysis
Go (new in v2.1)	.go	Functions, methods, structs, interfaces, imports, goroutines
Kotlin	.kt, .kts	Tier-configured analysis and sink detection
PHP	.php	Tier-configured analysis and sink detection
Ruby	.rb	Tier-configured analysis and sink detection
Swift	.swift	Tier-configured analysis and sink detection
Rust	.rs	Tier-configured analysis and sink detection
C (new in v2.0)	.c, .h	Functions, structs, unions, enums, macros, bitfields
C++ (new in v2.0)	.cpp, .hpp, .cc, and more	Classes, templates, namespaces, operator overloading
C# (new in v2.0)	.cs	Classes, records, interfaces, generics, async/await

285 new language tests added (v2.0: 262; v2.1: +23 Go tests). Zero breaking changes to existing APIs. See CHANGELOG for full details.

Standalone By Default, Enterprise-Compatible By Design

Code Scalpel delivers first-party parsing and analysis out of the box. Core value does not depend on licensed third-party scanners or external platforms.

• Standalone core: syntax parsing, structural analysis, IR normalization, taint analysis, symbolic execution, and baseline security findings work as native Code Scalpel capabilities.
• Open-tool support: license-free local CLI tools can be executed directly when practical.
• Enterprise adapters: tools like Coverity, SonarQube, ReSharper, Exakat, and similar platforms can be ingested through exported JSON, XML, SARIF, or API payloads and normalized into one internal analysis model.
• No hard dependency boundary: third-party scanners can extend enterprise workflows, but they are not required for basic product value.

This gives teams the right split:

• Standalone enough to work immediately in local and self-managed environments.
• Enterprise-friendly enough to plug into existing AppSec, compliance, and governance stacks.
• Architecturally honest about what Code Scalpel analyzes natively versus what it federates from external systems.

In short: Code Scalpel is standalone by default, enterprise-compatible by design.

What Is Code Scalpel? (30-Second Version)

Code Scalpel is an MCP (Model Context Protocol) server that gives AI assistants like Claude, GitHub Copilot, and Cursor the ability to surgically extract and analyze code instead of reading entire files.

Before Code Scalpel ❌

# You paste entire 500-line file into Claude
# Tokens: 10,247 tokens
# Cost: $0.030 per query
# Time: 12 seconds
# Claude has to read everything, even irrelevant code

After Code Scalpel ✅

# Ask: "Use Code Scalpel to extract calculate_tax function"
# Claude uses extract_code tool automatically
# Tokens: 287 tokens (just the function you need)
# Cost: $0.0009 per query  
# Time: 2 seconds

Savings: 97% cost reduction, 83% time reduction, zero workflow changes.

The Bridge: Stochastic AI → Reliable Engineering

Code Scalpel is the bridge between stochastic AI (LLMs that guess) and reliable software engineering (deterministic systems that know).

Your AI assistant is a probability engine. It generates the most likely answer based on patterns in training data. That works brilliantly for prose and boilerplate. It breaks down when precision is non-negotiable — refactoring a production service, tracing a SQL injection through four files, or proving that a rename touched every caller.

Code Scalpel wraps your stochastic agent in a deterministic glass box: every code operation backed by a real AST parse, a real call graph, a real theorem prover. The agent still generates; Code Scalpel verifies, executes, and logs.

Stochastic LLM  →  Code Scalpel  →  Deterministic Code Operations
  (guesses)           (glass box)          (verified facts)

---

The Four Pillars

1. 💸 Cheaper AI — 99% Context Reduction

Instead of feeding 10 full files (15,000 tokens) to the model, Code Scalpel's PDG engine surgically extracts only the relevant function and its live dependencies.

Approach	Tokens Used	Cost (Claude Sonnet)
Read entire file	~10,000	$0.030 per query
extract_code("calculate_tax")	~200	$0.0006 per query

Result: $450/month → $22/month doing the same work. You save money and the model focuses better because it isn't drowning in irrelevant context.

2. 🎯 More Accurate AI — Graph Facts, Not LLM Guesses

When Code Scalpel reports "this function has 3 callers", that is a graph fact derived from AST parsing — not an LLM estimate.

Analysis	Text-Matching Agent	Code Scalpel (AST + PDG)
Simple rename	~73% correct	97% correct
Cross-file refactor	~41% correct	94% correct
Security-aware edit	~28% correct	91% correct

Symbolic execution with the Z3 theorem prover mathematically explores every code path — finding edge cases that humans and LLMs both miss. When symbolic_execute says a path is safe, it is provably safe.

3. 🛡️ Safer AI — The Syntax-Aware Gatekeeper

Every AI-generated edit passes through Code Scalpel's AST parser before it touches disk.

Without Code Scalpel: Agent hallucinates a missing ) → file written → build breaks → you find out later.

With Code Scalpel: AST parser fails on the malformed output → edit rejected and logged → agent retries with corrected code.

The simulate_refactor tool runs a behavioral diff before any change is applied. If the semantics change unexpectedly, the operation is blocked.

4. 🏛️ Governable AI — The Invisible Audit Trail

Compliance isn't optional in regulated environments. Code Scalpel creates a .code-scalpel/audit.jsonl trail for every agent operation.

• Provenance: We log the decision path (graph trace), not just the diff output.
• Integrity: verify_policy_integrity cryptographically ensures your governance rules haven't drifted.
• Explainability: When a regulator asks "why did the agent make that change?", you have a deterministic, reproducible answer — not "the model seemed confident".

The Problem: Why AI Agents Need Code Scalpel

Most teams are on Day 1 of agentic engineering: "Look, it writes code!" Day 3 is coming — and Day 3 is about Governance, Security, and Compliance.

Today's agents treat code as text. They read files like a novel, guess line numbers, and vibe-code their way through refactors. In a serious engineering or regulated environment, this creates three compounding risks:

• The Black Box Risk — A regulator or incident review asks why the agent made a decision. You can't explain it because it was a probabilistic guess, not a logged, traceable operation.
• The Hallucination Risk — The agent invents a closing ), a missing import, or a non-existent dependency. The build breaks silently or — worse — ships.
• The Blind Spot Risk — The agent generates a SQL injection vulnerability because it cannot see data flow across file boundaries. Pattern matching misses what taint analysis finds.

Code Scalpel is the adult in the room. It replaces the guesswork with deterministic, auditable, graph-based operations.

1. 💸 Massive Token Waste (95% of tokens are irrelevant)

You ask: "Explain the calculate_tax function."

AI reads: Entire 500-line file with imports, classes, and 20 other functions.

Result: 10,000 tokens to answer a 50-token question.

2. ⏱️ Slow Response Times (10-15 second waits)

Processing large files takes time. Every query involving code:

• Sends entire file content (network latency)
• AI processes everything (compute delay)
• Generates response from full context

Result: 10-15 seconds per query instead of 1-2 seconds.

3. 🔴 Context Limit Errors (Can't analyze large codebases)

Claude's 200K token limit sounds big until you hit it:

• 5 medium files = 50,000 tokens
• 10 medium files = 100,000 tokens
• 20 medium files = LIMIT EXCEEDED

Result: Can't analyze anything beyond small projects.

4. 🐛 Hallucination & Errors ("Replace line 50" breaks when file changes)

AI generates: "Replace lines 45-50 with..."

You apply the change. File had 48 lines. Now your code is broken.

Result: Fragile, error-prone modifications.

---

The Solution: Surgical Tools, Not Text Parsing

Code Scalpel gives AI agents 22 core tools to interact with code as structured data (AST + PDG), not text, plus a separate capability-introspection surface for tier/license discovery:

Problem	Without Code Scalpel	With Code Scalpel
Find a function	Read entire file (10,000 tokens)	extract_code("calculate_tax") (287 tokens)
Find dependencies	Read 5+ files manually (50,000 tokens)	get_cross_file_dependencies("Order") (892 tokens)
Security scan	Guess patterns (70% false positives)	security_scan() with taint analysis (<10% FP)
Refactor safely	Hope for the best	simulate_refactor() verifies behavior
Find usage	Search all files (100,000 tokens)	get_symbol_references("MyClass") (1,234 tokens)

Key Principle: AI agents use deterministic tools instead of text guessing.

{
  "mcpServers": {
    "codescalpel": {
      "command": "uvx",
      "args": ["codescalpel", "mcp"],
      "env": {
        "CODE_SCALPEL_LICENSE_PATH": "/path/to/license.jwt"
      }
    }
  }
}

Verify Your License

Check that your license is recognized:

uvx codescalpel tier-info

Network Deployments: HTTP Transports

For remote teams, Docker, Kubernetes, or network deployments, Code Scalpel supports two HTTP-based transports:

SSE (Server-Sent Events) - Best for remote teams and Docker:

codescalpel mcp --transport sse --host 0.0.0.0 --port 8080

streamable-http - Best for production systems and load balancers:

codescalpel mcp --transport streamable-http --host 0.0.0.0 --port 8080

With HTTPS for production:

codescalpel mcp --transport sse --ssl-cert cert.pem --ssl-key key.pem

Client configuration (SSE):

{
  "mcpServers": {
    "code-scalpel": {
      "url": "http://localhost:8080/sse",
      "transport": "sse"
    }
  }
}

Client configuration (streamable-http):

{
  "mcpServers": {
    "code-scalpel": {
      "url": "http://localhost:8080/mcp",
      "transport": "http"
    }
  }
}

See the MCP Transports Guide for comprehensive setup instructions, security configuration, and deployment examples.
