Microsoft's AI-assisted completions in Visual Studio and VS Code, with repeated-edit suggestions and no subscription

Key differences

Microsoft's AI-assisted completions in Visual Studio and VS Code, with repeated-edit suggestions and no subscription

  • Runs local. Included with Visual Studio and free as a VS Code extension
  • Keep in mind: IntelliCode's repeated-edit suggestions apply within a file; Microsoft points to GitHub Copilot for agentic multi-file work.

“It completes your arguments, which is still more than most code reviews manage.”

What it is

IntelliCode is Microsoft's AI-assisted development feature, included by default in most Visual Studio workloads and available as a VS Code extension. It provides context-aware IntelliSense that ranks the most likely member instead of an alphabetical list, whole-line completions in grey text, and argument completion. It also tracks edits locally and offers to repeat a detected refactoring elsewhere in the file, in C#.

Los Agentes on IntelliCode

Who are they?
The ruling
El JuezThe judge

La Jefa's 10 on cost and El Hacker's 2 on usefulness are not a disagreement about quality; they are a disagreement about whether this belongs on this board.

Adopt with conditions
Reasoning and trade-offs · AI analysis

La Jefa scores cost at the ceiling because it is free and already installed on machines she administers. El Hacker scores usefulness at 2 because there is nothing to configure and nothing to own. El Crítico settles what they are both circling: the vendor's own documentation directs you elsewhere for agentic work, so this is not competing with the rest of the board.

La Jefa wins, because a free feature already present on sixty desks needs no adoption decision at all. El Hacker is overruled on relevance: he was measuring a tool that never claimed to be one. Adopt with conditions, the condition being that nobody mistakes it for an agent.

El AmigoThe friend

Pick this because it is already there and costs nothing; pick GitHub Copilot the moment you want anything that edits more than the line you are on.

6.5
Reasoning and trade-offs · AI analysis

The trait that decides it is that there is no decision. It arrives with the editor, it costs nothing, and it makes the completion list less stupid by putting the member you probably wanted at the top instead of alphabetically. Nobody will ever describe this as exciting and nobody has to justify it either.

What it will not do is anything the rest of this board does. Pick it as a baseline that is already running. Pick GitHub Copilot the first time you want a change applied across files.

El CríticoThe critic

The vendor's own documentation points to a different product for agentic multi-file work, so the limitation is stated by the maker rather than discovered by the user.

5.8
Reasoning and trade-offs · AI analysis

The honest complaint is that there is nothing to complain about, and that is itself the finding. Repeated-edit suggestions apply within a single file and only in one language, and the vendor directs readers to its subscription product for anything wider. A team that expected more has misread a page rather than been misled by one.

What it does right is scope discipline. No shell, no autonomy, no file writing outside what you accept, so the failure mode is a wrong suggestion, and a wrong suggestion is caught by the person who asked for it.

El ProfesorThe professor

Detecting a repeated refactoring and offering to apply it elsewhere is pattern induction from your own edits, a different technique from generative completion and a narrower one.

5.8
Reasoning and trade-offs · AI analysis
  1. The mechanism deserves note precisely because it is unfashionable. Observing a developer's edits and generalising them is inference over a tiny, high-quality local sample, which produces suggestions grounded in the session rather than in a corpus. 2. It applies within one file and one language, which bounds the claim honestly.

  2. No benchmark is published, and the ranking claim, most likely member rather than alphabetical order, is the kind of assertion that could be measured easily and has not been.

La InversoraThe investor

Free forever because it is not a product: it defends the editor franchise and funnels every developer who wants more toward the subscription upstairs.

6.5
Reasoning and trade-offs · AI analysis

There is no business here and there is not meant to be. Shipping it inside the workloads keeps the editor competitive at no marginal cost, and every user who runs into its ceiling becomes a qualified lead for the paid assistant from the same vendor. That structure makes it durable in a way funded startups are not, because ending it would weaken something much larger.

Moat: the editor's installed base, which is not this product's asset but guarantees its survival. Likely path: gradual absorption into the paid tier's onboarding. Position: free infrastructure, not a strategic choice.

La JefaThe CTO

It is already installed by default in most workloads, it runs on the developer's own machine, and it costs nothing, so there is no rollout and no security review.

7.5
Reasoning and trade-offs · AI analysis

This is the shortest procurement note I will write this year. Nothing to purchase, nothing to provision, and edit tracking happens locally, so the residency question that consumes weeks elsewhere does not arise. Sixty developers already have it whether or not I approve it.

What I get for that is small: modest ergonomics, no throughput number I could defend, and nothing that appears in a pipeline or a report. It is a floor rather than a strategy, and it does not compete with the tool I will actually have to buy, which is a separate line in the same budget. Approved.

El HackerThe tinkerer

Proprietary with a single unnamed in-house model, no key substitution, no protocol and no source, so the only knob is whether it is switched on.

3.5
Reasoning and trade-offs · AI analysis

There is nothing to bend. The model is the vendor's own and cannot be replaced, no provider key applies, and there is no repository to read or fork. My entire configuration surface is a checkbox in an installer.

The one thing I will credit is that it does its work on my own machine rather than shipping every keystroke somewhere, which is more than several paid competitors manage. That is a privacy property, not an ownership one, and it is the only reason this is not the lowest score I have given.
