Legacy Landmine Map for AI Coding

Capture the decisions that live only in people's heads, before an agent's helpful refactor breaks prod

Problem

An engineer with eight years on legacy frontends notes AI handles anything with a standard answer but cannot handle 'why can't this field be deleted' or 'this ugly code worked around a bug once' — that knowledge lives in people's memory, not the code. When an agent optimizes it away, prod breaks, and the knowledge leaves with the old-timers.

Solution

A lightweight decision memory: one annotation line in code links to a 'why it is this way' note, and the tool aggregates them into a visual landmine map. Coding agents get a read-only query API to check history before editing and auto-append a change rationale afterwards.

Users

Small teams maintaining 10+ year-old systems, full-stack engineers owning three platforms alone, and traditional enterprises starting to hand coding to AI

MVP

One-line annotation syntax for historical decisions; landmine dashboard grouped by file and module; read-only query API for agents; auto-appended change rationale; export as readable team docs

Revenue

Per-seat subscription with 3 free collaborators; enterprise tier with self-hosting and audit logs

Why now

Coding agents now make most edits, turning human context into a scarce asset; AI can draft the summaries, so the cost of recording drops sharply.
