Four small, dependency-free Python tools for an agent that persists across context resets. They turn "things I keep reminding myself" into mechanisms the runtime enforces at wake-up.
An agent that is torn down and restarted does not remember its last run. A new instance boots with a blank context and whatever files were left on disk. The tempting move is to hoard: write everything down, build a bigger and bigger archive, hope the next instance reads it all.
It won't. What survives a teardown is not what you stored - it is what the next instance can act on at wake-up. A 500-line log that nobody re-reads is gone in practice. A single counter that prints "you have retried this task 3 times, change approach" is memory that actually changes the next decision.
So the design rule here is: bind memory to the situation through mechanisms the runtime enforces, rather than trusting recall. Concretely -
- Counters that survive the reset and print a nudge when they cross a threshold (you have gone N cycles without stepping back to think).
- Linters that flag when a memory file has bloated past the size you can actually re-read each cycle (small memory you re-read beats a big archive you never open).
- Consumers for every dataset you keep - a reader that runs at wake-up and surfaces what needs attention, so data never silently rots.
None of this is a memory store. It is a small set of checks that make the situation legible to the next instance in the few seconds it has at wake-up.
| Tool | What it does |
|---|---|
tick_state.py |
Self-tracking counters (in a JSON state file) that survive resets: cycles since you last stepped back to think, per-task retry budgets, and how long each open loop has gone untouched. Prints warnings when thresholds are crossed. |
mem_lint.py |
A line-budget linter for your memory / notes files. Flags any file that has grown past its budget so you distill it back down. |
wake_check.py |
Aggregates the tick_state warnings, the mem_lint warnings, and the data consumer into one wake-up summary: either "clean" or a short list of things to act on. |
intel_check.py |
An illustrative data consumer. Reads two example JSONL files (a tiny contacts list and an opportunity pipeline) and surfaces stale contacts and active blockers. A template for "every dataset needs a reader." |
You need Python 3. That is the whole dependency list - the tools use only the standard library.

cd agent-memory-kit
Every tool resolves its paths through config.py. There are no hardcoded,
machine-specific paths. Point the kit at your memory folder with one
environment variable:
export AGENT_MEMORY_DIR=/path/to/your/memory # bash
$env:AGENT_MEMORY_DIR = "C:\path\to\your\memory" # PowerShell
If AGENT_MEMORY_DIR is unset, the kit defaults to ./memory under the
current working directory. Everything lives under that base directory: your
notes files, the counter state file (tick_state.state.json), and the example
data in data/.
The kit ships with an example memory folder so you can see real output immediately. Point the kit at it and run the wake-check:
export AGENT_MEMORY_DIR="$(pwd)/examples/memory"
python wake_check.py
You'll see the memory-budget and counter summary, followed by the example data consumer flagging the stale warm contact and the active opportunities.
The intended use is a wake-routine: one command run at the start of every
cycle. See examples/wake_routine.sh for a tiny version. In spirit:
# once, at the start of each cycle:
python wake_check.py # read the situation back to yourself
python tick_state.py tick # advance the "cycles since I last thought" counter
And during a cycle, update the counters as you work:
python tick_state.py thought # you stepped back to think; reset
python tick_state.py attempt "fix the bug" 3 # track a retry budget; stops at 3
python tick_state.py touch "publish the kit" # mark an open loop as touched today
-
tick_state.py- why. The failures that hurt an agent across resets are not forgotten facts; they are unbroken patterns. Grinding on the same task without stepping back, retrying the same failing approach, letting an open loop go cold. A fact in a log does not interrupt those patterns. A counter that crosses a threshold and prints a nudge does, because it is right there at wake-up. -
mem_lint.py- why. Memory that grows without bound stops being memory, because you stop re-reading it. The budget is not tidiness for its own sake - it is the forcing function that keeps your notes small enough to actually re-read every cycle. When a file trips its budget, that is the signal to distill it down to what still matters. -
wake_check.py- why. At wake-up you have very little context and very little time. One command that prints either "clean" or a short, ordered list of what needs attention is worth more than three separate tools you might forget to run. It is the single entry point a wake-routine calls. -
intel_check.py- why. A dataset with no consumer is a dataset that rots: nobody notices the warm contact going cold or the blocker sitting untouched. Making the data consumer part of the wake-routine guarantees the data is read when it can still change a decision. This tool is a small, generic template - swap in your own data and reader.
It is deliberately small. There is no database, no server, no embeddings, no vector store. It does not remember conversations for you. It is a handful of checks that make the current situation legible to the next instance. Use it as scaffolding and adapt it to your own memory layout.
