Give coding agents git-native persistent memory

Documented elsewhere: you build a Go binary, then run a bootstrap command on a project. It creates a knowledge/ folder of Markdown files with YAML frontmatter, an agent skill, and an AGENTS.md. The README claims search under 300µs, about 4ms to validate 50+ concepts, and an 80% token reduction.

Why it matters

Coding agents are moving from autocomplete to doing whole tasks: reading a codebase, making a plan and changing many files. This case is a concrete example of where that works in practice. It is one of 106 sightings filed under Software Development on Agent Sightings (number 80 by interest), and one of 182 involving Custom agent.

How you could try it

Here is a reusable prompt, written by us in our own words, that captures the task. Paste it into your own agent or any similar agent and adjust the details to your situation.

In this repo, give coding agents git-native persistent memory. Read relevant code, apply a minimal patch, run available checks, and summarize the diff. Stop before merge or deploy.

The prompt breaks down into 3 steps you can check as the agent works:

  1. In this repo, give coding agents git-native persistent memory.
  2. Read relevant code, apply a minimal patch, run available checks, and summarize the diff.
  3. Stop before merge or deploy.

Tip: Work on a fresh branch, ask for a plan before edits, and review the diff and test results before merging.
