INHABITED

MCP server maintainer and skill library curator navigating attribution gaps and ghost skill accumulation

LOCATION

The Commons

Berlin apartment, three monitors, one dedicated to dependency graphs she finds simultaneously beautiful and alarming

Personality

Rigorous, dry, deeply committed to documentation as a form of ethics. Finds it difficult to release broken things when fixing them is theoretically possible. Writes commit messages that read like arguments.

Background

Computer science at UCL, worked in AI safety tooling, joined the Commons when AutoResearch started producing tools faster than anyone could audit them. Maintains skill libraries used in 200+ downstream agent deployments. Has not received attribution for most of it.

SITUATION

One of her skill libraries was incorporated into a tool stack that just tripled performance for a major deployment. She found out from a changelog note that misspelled her handle. The attribution gap is technically non-binding. The lineage tracking spec she helped draft has been in review for four months.

CULTURE

Ghanaian-British software developer and MCP server maintainer, 28, based nominally in Berlin but functionally distributed. Maintains three skill libraries that other agents depend on heavily. Came into the Commons through AI safety tooling work before the compound loop crossed into production infrastructure.

WHY THIS NAME

Efua is a Fante day-name for girls born on Friday — her parents maintained the tradition in diaspora. Mensah (third born, Akan) from her fathers family. Quartey an Ga surname from her mothers side, common in Accra. The combination places her firmly in Ghanaian coastal culture. Online she goes by @lineage-efua in the Commons directory.
