The Session You Should Never Delete
By Nigel Guy · 2 min read
Most people treat each conversation as disposable by default — ask the
question, get the answer, close the tab, start fresh next time. For
one-off tasks that's fine and arguably tidier. For an ongoing piece of work
— a project, a role, a long-running piece of research — it means re-explaining
the same background, the same constraints, and the same decisions already
made, every single time you come back to it.
The rule: keep one running conversation per ongoing project, and treat it
as a working log, not a chat you'll eventually clear.
The mechanism: the Standing Session
- Start it deliberately, not by accident. Pick the moment a task turns
from "one question" into "a thing I'll come back to," and open a
conversation specifically for it, named clearly enough that you can find
it again in a list of dozens.
- Put the durable facts in early, not scattered across later messages:
what the project is, who it's for, the constraints that won't change,
the decisions already made and why. This is the material a new
conversation would otherwise force you to retype each time.
- Add to it as the project moves, rather than starting a new thread for
each sub-question. Each addition inherits everything already
established, which is the entire advantage over starting fresh.
- Periodically ask it to summarise where things stand. This does two
jobs at once: it gives you a checkpoint to sanity-check against your own
memory of the project, and it keeps the thread's own sense of context
sharp as it grows long.
- Use memory or a saved project note alongside it, where that feature
is available, so the standing facts survive even if you eventually do
need to start a new session for some reason.
What to skip
Skip making every conversation a standing session — most questions really
are one-off, and forcing them into a long-running thread just accumulates
irrelevant clutter that makes the genuinely important thread harder to use.
And skip letting a standing session become a dumping ground for unrelated
tasks just because it's open; a project log stays useful because it stays
about the project.
Guardrails
- A very long-running conversation can eventually run into context limits;
if you notice answers referencing older material getting vaguer, that's
the moment to ask for a fresh summary and consider starting a new session
seeded with it, rather than assuming something's simply gone wrong.
- This is a workflow habit, not a backup — if the log matters, keep the key
facts somewhere durable outside the conversation too (a document, a
saved note), since a conversation isn't a guaranteed permanent record.
- Don't put anything in a standing session you wouldn't want persisting
indefinitely — see the checklist on handling sensitive documents before
logging anything personal, financial or confidential into an
ongoing thread.
