The Change Impact Analysis Tool
Describe a feature or change in plain language and get an estimate of the files, APIs, and risks it touches — the blast radius an agent or planner needs before a single line is written, on infrastructure you control.
Every estimate is a guess about what a change touches
When a stakeholder asks "how big is this?", the honest answer depends on which files, APIs, and dependencies the change ripples through — knowledge locked in the codebase that estimates rarely consult.
Estimates ignore the code
Sizing happens in a meeting, not against the actual repository.
Hidden ripple effects
A "small" change touches APIs and modules no one anticipated.
Risk is unspoken
The risky parts of a change surface only mid-implementation.
Planning is slow
Mapping impact by hand for every proposed change doesn’t scale.
Impact, estimated against the code
Scope
Files and APIs impacted
The blast radius, estimated.
From a plain-language description of a feature or change, the tool estimates the files and APIs it’s likely to touch — grounding the size of the work in the actual codebase rather than a hunch.

Files + APIs
Risk
Risks surfaced up front
Before, not during.
It flags the risks a change carries — the fragile areas and wide dependencies — so a planner or agent can weigh them before committing, not discover them mid-build.
Before you build
Governance
On-premise analysis
Source stays internal.
Analysis runs against a snapshot inside your perimeter with audit logging, so impact estimation never exposes code.
IP-safe, logged
Parameters
The impact_analysis tool accepts these inputs when an agent calls it. Required inputs are flagged.
Where impact analysis pays back
Estimation
Size a proposed feature against the real codebase.
Risk review
Surface the risky parts of a change before approval.
Sprint planning
Scope stories with grounded impact, not guesses.
Architecture decisions
See what an approach would touch before choosing it.
Refactor scoping
Bound a refactor by its estimated blast radius.
Agent planning
Let a planning agent ground its estimates in code.
Assigned to agents, orchestrated as networks
On VDF AI, an industry’s use cases map to agents, and you assign tools like this one to those agents. Compose multiple agents into a governed, on-premise network.

Questions about the Change Impact Analysis tool
What does the change impact analysis tool do?
Given a plain-language description of a feature or change, it estimates the files and APIs the change is likely to touch and the risks it carries — the blast radius needed to scope and plan work against the real codebase.
How accurate is the estimate?
It is an estimate grounded in the repository’s structure and dependencies, meant to inform planning and surface risk early — far better than a meeting-room guess, and a starting point a human refines.
What input does it need?
A feature_description in plain language, plus optional owner, repo, and ref to ground the analysis in a specific repository.
Is our code exposed?
No. Analysis runs on-premise against a snapshot with audit logging.
How does it pair with other tools?
It builds on the dependency graph and reference finder and feeds planning and estimation agents.
