I work in a massive monorepo with a bunch of different services. Over the last month, I realized I was starting Claude Code sessions everywhere. I would hit a weird issue, remember I had already solved it with the agent a few days ago, and then realize I had no way to easily find that specific session. CC stores these as JSON files, keyed by the directory you happened to be in at the time.

I built Wallfacer because I needed a way to search and resume these sessions without messing with the source of truth. It operates as a strictly read only overlay. It just reads the local files, extracts the working directory and first prompt, and lets you manage the metadata in a local SQLite database.

I just tell claude "Few days ago we worked on xxx, find the session and let's resume."
