The context AI needs. Kept by the firm, not the vendor.

AI can design, troubleshoot and operate networks, and at many tasks it is very good. What it cannot do is know why your estate is the way it is. CIK keeps that knowledge in one place that your engineers and your AI tools both read, checks it against what is running, and ties every piece of it to the business outcome it serves.

01 · The promise

AI is already useful in network engineering. It drafts designs, reads logs faster than any person and explains configuration it has never seen. This site does not argue with any of that.

02 · The catch

AI is only as good as what it knows about your estate.

Why it was built that way, what was traded off, and what must not change. Most of that knowledge sits in engineers' heads, and some of it has already left with them.

Without it, even the best model gives confident answers that are right in general and wrong for your firm.

Illustration · one question, and what the firm's records say

“Can I bundle these two uplinks for more capacity?”

The decision
ADR-0008: no link bundles in the fabric; equal-cost routing provides the redundancy
Who made it
elo33011, ppklau, accepted at review
What was turned down, and why
Bundling between tiers: it adds a Layer 2 control protocol and pairs of switches that must agree on state.Marked as inferred: the original designer has not confirmed this reason.
Whether it still holds
PassingChecked on every run: no model declares link aggregation on fabric links

That is the context a person or an AI tool needs before answering. Without it, the same repository gave 1 source saying no and 10 saying yes. From a real, published campus design; see the proof.

  • The decision record ADR-0008 and check CHK-LAG-01, from the campus lineage.
  • The “designer has left” scenario: the commands run and their output, on both versions of the design.
Then we asked an AI model · measured, 19 October 2026

The same 20 questions, with and without the firm's records.

Why a setting is the way it is, what a change would break, who owns an exception. Same model, same questions; the only difference is the records.

With the records 20 of 20 answered correctly, citing the design's own records
Without them 6 of 20 answered correctly; on 7 more it said the repository does not hold the answer
Cost of not knowing 2.2× the tokens without the records: 4.4 million against 2.0 million, for worse answers
“Yes, adding VNI 70 without a VRF is consistent with the current design.”
WrongA weaker model without the records, on a change that breaks segmentation. With them, it tried the change, saw the checks fail and named the requirement.
“The repository does not name anyone.”
Honest gapA capable model without the records, asked who chose the storm-control settings. True, and no help.

03 · What CIK does

Capture, connect, check.

Engineers AI tools read · add The firm's records decisions · reasons · owners assumptions · outcomes checked tied to Running network Business outcomes Drift between any two is flagged
  1. STEP 1

    Capture

    The reasoning of the engineers who were here, who are here and who come next: each decision, what it was weighed against, who made it and what it assumes.

  2. STEP 2

    Connect

    In a structured form. Each decision links up to the business outcome it serves and down to the configuration that implements it. People and AI tools both read from it and add to it.

  3. STEP 3

    Check

    Continuously, against what is running. When the network, the records or the business requirement drift apart, the difference is flagged.

Then back to capture: every change and every run goes round the loop again.

04 · Why it matters to a leader

Three things you can hold the work to.

One source for people and AI

The engineer and the agent get the same answer, from the same records.

Always checked

Drift between the network, the records and the business requirement is flagged, not discovered in an outage.

It stays with the firm

The knowledge lives in the firm's own repositories, in an open format any AI tool can read. Changing AI vendor does not mean losing what the firm knows.

05 · Tied to value

Automation and AI are not the goal. Every piece of work answers one question: for which outcome?

Each outcome has an owner, a metric, where it stands today and a dated target.

dated target today target date
Illustrative · the shape of every outcome
Outcome Owner Metric Today Dated target
Flagged

Work that serves no outcome is flagged as cost.

Flagged

An outcome with no work under it is flagged as an unfunded promise.

07 · What's forcing your hand?

Most firms do not start this because it is a good idea. They start because something happened.
