Context Portability: Move Any Conversation to Any Model Without Losing a Step

JetBrains found 67% of developers use multiple AI tools — but almost none of them have a way to move work between models without re-explaining. That is the context portability gap: your work is locked inside whichever chat happened to be open.

Context portability is the ability to take a conversation's real state — goal, decisions, constraints, progress — and continue it in another model in seconds. This guide shows the pattern. It is the core of the LayerFlow workspace; the docs document the summary format.

What actually needs to travel

• Goal: the thing you are building or fixing.
• Decisions: what was already agreed, so the new model does not re-litigate.
• State: where the work stopped, file by file.
• Constraints: budgets, conventions, security rules.
• Failures: what was tried and rejected.
• Next action: the exact thing to do next.

Transcripts do not travel. Raw history pasted into a new model is expensive, noisy, and often counterproductive. What travels is the distilled state — roughly 1,000 words of signal instead of 15,000 words of talk.

The AI summary pattern

An AI summary is a structured block with those six fields, formatted so any model can consume it as a continuation prompt. The opening line tells the model the rules: continue this work; restate the goal before starting; preserve the constraints; do not revisit settled decisions.

Format matters less than completeness — but consistency matters a lot. Teams that standardize on one summary template can automate the whole flow: extract from the old session, compress, hand to the new model.

When porting is a superpower

• Rate-limited mid-task: switch models instead of waiting or restarting.
• Quality plateau: a fresh model on the same state often finds the error the first one missed.
• Cost optimization: move long-tail work to cheaper models without losing context.
• Best-of-breed: use the strongest model for each stage — planning here, coding there.

Common mistakes

• Porting the transcript instead of the state — the new model drowns in noise.
• Leaving out failures, so the new model repeats the old mistakes.
• Hand-editing the summary every time instead of using a template.
• No verification step — a model that misread the goal will confidently do the wrong thing.
