Saving Context Window history with timestamps

I’ve run into the issue where the AI starts cutting off responses as our chats get longer. I’ve figured out a daily routine to back up my prototyper-context-state.json and prototyper-thread.json files, which is great for saving my chat history before I clear the context.

But now, I’m hoping to do something more with these saved logs.

Here’s what I’m trying to figure out: Is there any way to get a timestamp for each individual message (from me or the AI) that’s in the prototyper-thread.json file? When I look at my backed-up files, I see a lastEditTimestamp for the whole chat, but I can’t find separate timestamps for each message in the history part.

Why I’m asking / What I’m trying to do: Since I was already doing daily backups to handle the context window, I figured I should make it a regular routine and try to get something more useful out of these logs. I’m still figuring out the best way to do this, so I actually brainstormed a bit with Gemini and put together some ideas in a document I’m calling “Saving Context Windows on the Daily: Enhancing AI-Assisted Workflows…” (It’s a long and unedited research dump, just FYI!)

My first thought was to feed the whole daily chat log to Gemini for a summary, but (unsurprisingly!) the file was too long, and it needed shorter chunks of text. I could manually break up the file for a single day’s session, but my ideal way to get these smaller, more manageable files would be to split the log based on my natural work breaks. I usually work on a project throughout the day, and when I finish a feature or task, I’ll take a break – typically anywhere from 45 minutes to a few hours.

So, if I could find a way to get timestamps for each message, I could automatically split these long prototyper-thread.json files into what I’m thinking of as “work sessions” by looking for those big time gaps (like over 45 minutes) between messages.

If I can get these separate session logs, I could:

  • Make shorter, focused summaries for each session.
  • Give these short summaries to the AI the next day so it actually remembers what we were doing (to get around the daily “memory wipe”).
  • Maybe even spot some patterns in how I’m working with the AI over time and get better at it.

Basically, I’m trying to turn this context limit problem into a chance to make my whole process of working with the AI smoother and more organized.

Helpful posts I’ve already seen: I’ve already learned a lot from these awesome community posts, and they helped me get my current backup system going:

So, my questions are:

  1. Does anyone know if there are timestamps for each message logged anywhere, even if they’re not obvious in the prototyper-thread.json file?
  2. Is there maybe another way to save or export the chat that might have more details, like individual timestamps?
  3. If getting timestamps for each message isn’t possible, has anyone else found a good way to figure out where one “session” ends and another begins in these logs?

Any ideas, tips, or pointers would be super appreciated!

Ok, solved my own issue in a work around way; still would like timestamps, but I can see this working generally since I realized that when I’m working, I naturally tell the AI that I’m taking a break, and when I take a break, it usually means that its been a certain amount of time (a couple hours) or that I’ve gotten to a stopping point with working with features – so taking that into consideration, and gonig back and asking previous Gemini conversations about my key phrases; I got soem exact phrases and close phrases and then used that to create a script to help me break up my larger script; and now that I know that is a part of the process, I’ll know to be sure to type out when I’m taking a break so that the script will catch it for the daily backup process.

sharing in case anyone else would find it helpful. (sorry if it is too wordy; still trying to get the tuning right and havent taken time to get things condensed down just right yet)

# AI Context Management and Daily Workflow

## Purpose

This directory and the associated scripts and procedures are used to manage the AI Prototyper's context in Firebase Studio. The goals are:
1.  To prevent the AI from cutting off responses due to an overly large context window by enabling daily context clearing.
2.  To maintain a daily backup of the AI's full interaction context for history, reference, and **long-term analysis**.
3.  To establish a workflow for **segmenting daily interactions into meaningful "work sessions"** (currently based on user-indicated break phrases due to the lack of per-message timestamps in logs).
4.  To create **concise, AI-assisted summaries from these sessions**, which can then be used to **re-contextualize the AI for subsequent sessions** (daily, weekly, monthly, or for specific projects/tasks), thereby overcoming its natural memory limitations and enhancing collaborative efficiency.
5.  Ultimately, to **improve the human-AI partnership** by analyzing interaction patterns and building a more strategic approach to context management, as outlined in [community discussions](https://community.firebasestudio.dev/t/saving-context-window-history-with-timestamps/14309) and personal research on enhancing AI-assisted workflows.

## Daily Workflow (To Be Performed After Each AI Session)

Here are the recommended steps to follow daily:

### 1.a. Back Up Current AI Context (Full Backup)

Before clearing the live context, ensure you save its current state.
-   **Action:** Open the Firebase Studio terminal. Navigate to the `scripts` directory and run the daily backup script:
    ```bash
    cd /home/user/studio/context_backup/scripts/
    ./daily_backup_context.sh
    ```
-   **Result & Verification:** This will create a new dated subfolder inside `/home/user/studio/context_backup/data/` (e.g., `data/2025-06-01/`). Check that this folder contains the two timestamped `.json` backup files. Note the exact filename of the `prototyper-thread-YYYYMMDDxxxxxx.json` file.

### 1.b. (Recommended) Segment Thread Log into Sessions

To make reviewing and summarizing easier (especially for the AI summarizer), split the full thread backup into smaller segments.
-   **Action:** While still in the `scripts/` directory, run the Python splitting script.
    ```bash
    # Example: Replace YYYY-MM-DD and the timestamped filename
    python3 ./split_sessions.py \
      --input_file /home/user/studio/context_backup/data/YYYY-MM-DD/prototyper-thread-YYYYMMDDxxxxxx.json \
      --output_parent_dir /home/user/studio/context_backup/data/YYYY-MM-DD/
    ```
-   **Result & Verification:** This creates a `sessions/` subfolder inside your dated backup directory (e.g., `data/YYYY-MM-DD/sessions/`) containing files like `thread_segment_1_X.json`.

### 2. Clear the AI Context Window

(Content of this section remains the same: Method A `/clear`, Method B manual edit)
* **Method A: Using the `/clear` command (Try this first)** ...
* **Method B: Manually Resetting the Context State File (If `/clear` is not effective or available)** ...

### 3. Generate AI-Assisted Summaries from Session Segments

Leverage another AI instance (e.g., a separate Gemini window) to create concise summaries from your segmented session logs. These summaries serve as "artifacts" of your work and help re-contextualize your primary AI Prototyper in future sessions.
-   **Process:**
    1.  In your separate AI (Gemini) window used for summarization, provide it with your research document ("[Saving Context Windows on the Daily...](https://github.com/its-a-lisa/personal-handbook/blob/main/Saving%20Context%20Windows%20on%20the%20Daily%3A%20Enhancing%20AI-Assisted%20Workflows%3A%20A%20Strategic%20Framework%20for%20Log%20Synthesis%2C%20Trend%20Analysis%2C%20and%20Goal%20Achievement.md)") as a guiding prompt or foundational context for how summaries should be structured or what they should achieve.
    2.  Then, provide the content of one of your segmented `thread_segment_X_Y.json` files (from, e.g., `data/YYYY-MM-DD/sessions/`) to this AI.
    3.  Request the AI to generate a summary of that session segment based on your framework and the provided log segment.
-   **Storage:** Save the AI-generated summary as a text file (e.g., `session_1_summary_AI.txt`) inside a `daily_summaries/` subfolder within the corresponding dated backup folder (e.g., `/data/YYYY-MM-DD/daily_summaries/session_1_summary_AI.txt`).
-   **Long-Term Strategy:** These AI-generated session summaries can be periodically reviewed, refined, and potentially fed back to an AI (perhaps the same one used for summarization, or even the Prototyper itself) to create rolled-up weekly or monthly summaries, or combined for specific projects, to provide broader and more targeted context when needed.

## Start of Next Session

1.  **Select Relevant Summary:** Choose the appropriate summary to provide context. This might be a summary from the last session, a daily overview, or a compiled weekly/monthly/project-specific summary if you've started creating those.
2.  **Provide Summary to AI Prototyper:** Copy and paste the chosen summary into the AI Prototyper as one of your first prompts. For example:
    ```
    Hello AI. To bring you up to speed from our previous work (ref: YYYY-MM-DD, Session Z / Project Topic):
    [Paste your relevant AI-generated summary here]
    Our goal for this session is [your starting point for today].
    ```

## Important Files & Scripts

-   **Main Daily Backup Script:** `/home/user/studio/context_backup/scripts/daily_backup_context.sh`
    -   *Purpose:* Automates the backup of the full original AI context files into date-stamped folders within `data/`.
-   **Session Splitting Script:** `/home/user/studio/context_backup/scripts/split_sessions.py`
    -   *Purpose:* Splits the daily `prototyper-thread.json` backup into smaller session segments based on detected user break phrases, saving them into a `sessions/` subfolder.
-   **Source AI Context Files (Backed up by `daily_backup_context.sh`):**
    -   `/home/user/.idx/ai/prototyper-context-state.json`
    -   `/home/user/.idx/ai/prototyper-thread.json`

## Future Enhancements (Ideas)

This workflow can be expanded over time. Some ideas include:
-   Further automating the summarization pipeline, potentially chaining the output of `split_sessions.py` to an AI summarization script.
-   **Developing systematic methods for creating, storing, and retrieving various levels of summaries (session, daily, weekly, monthly, project-specific) to provide highly relevant and efficient context to the AI.**
-   Using AI to assist in identifying key decisions, code snippets, and action items from session logs or summaries for more structured knowledge management.
-   Implementing ways to search or pinpoint specific information from past backed-up contexts or the structured summaries.
-   Exploring community or official solutions for per-message timestamps to enable more precise, automated session splitting.

Remember to adapt file paths or commands if your setup changes.

Daily Backup Context

`#!/bin/bash

Get current date in YYYY-MM-DD format

current_date=$(date +%Y-%m-%d)

Define the parent backup directory

parent_backup_dir=“/home/user/studio/context_backup/data”

Define the specific directory for today’s backup

This creates a path like /home/user/studio/context_backup/2025-06-01

todays_backup_dir=“${parent_backup_dir}/${current_date}”

Create today’s backup directory (and parent if it doesn’t exist)

echo “Ensuring backup directory for today exists: ${todays_backup_dir}”
mkdir -p “${todays_backup_dir}”

Define a timestamp for unique backup filenames within the day

timestamp=$(date +%Y%m%d%H%M%S) # e.g., 20250601103055

Source files - double check these paths are correct for your environment

source_context_file=“/home/user/.idx/ai/prototyper-context-state.json”
source_thread_file=“/home/user/.idx/ai/prototyper-thread.json”

Destination filenames including the path to today’s dated folder

dest_context_file=“${todays_backup_dir}/prototyper-context-state-${timestamp}.json”
dest_thread_file=“${todays_backup_dir}/prototyper-thread-${timestamp}.json”

Check if source files exist before attempting to copy

if [ -f “${source_context_file}” ] && [ -f “${source_thread_file}” ]; then
echo “Source files found. Proceeding with backup…”
# Copy the files
cp “${source_context_file}” “${dest_context_file}”
cp “${source_thread_file}” “${dest_thread_file}”

echo "Backup successfully created in ${todays_backup_dir}/"
ls -l "${todays_backup_dir}/"

else
echo “Error: Source context file or thread file not found.”
echo “Checked for: ${source_context_file}”
echo “And for: ${source_thread_file}”
echo “Backup aborted.”
