umair/stalemap is a TypeScript tool that tells coding agents which dependencies changed after their training cutoff. It compares changes in JavaScript and TypeScript dependencies, produces a short guidance note, and writes it into AGENTS.md or CLAUDE.md. The latest release published on GitHub is v0.4.1.
The problem the repository targets is letting agents know about changes in dependencies released after the coding agent's knowledge cutoff. It compares pinned package versions, type definitions, and change history to produce the guidance note, and runs a format check once files have been edited. It also provides an MCP (Model Context Protocol) tool through which the agent can ask about the changes directly. The license is MIT and the repository has 32 stars.
The v0.4.1 changelog is not contained in the given information. This is an early-stage project, and the README states that one person maintains it. The validation introduced in the README is a result of using 66 tasks from pre-registered trials; the evaluation scores are 8.0 out of 10 for freshness, technology, and quality, while momentum remains low at 5.4. There are implementation modules, unit tests, and separate evaluation materials, so the structure and the validation basis are rich. It is still too early to judge whether to roll out an early-stage tool maintained by a single person across the whole organization. It is close to a project worth watching to see whether releases continue.
