deja-history SKILL.md skillA
This file is byte-identical to the first copy the registry indexed, one of 5 indexed copies. Same content hash, so the same checks give both the same grade.
deja-history from vshulcz/deja-vu is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add vshulcz/deja-vu/deja-history@git:20261015.154ecf9Pins git:20261015.154ecf9 in mdr.lock. Pin the fingerprint instead.

Search the user's past AI coding sessions. Holds what they already settled and never wrote into the repo (naming rules, banned or already-tried tools, required checks before merge, preferred values, who owns what). Use before your first edit in a task, before you call a change done or ready to merge, before you recommend a tool, library, design or reviewer, before re-debugging an error that may already be solved, when they say 'didn't we fix this before', 'what did we decide about X' or 'I…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
Search deja before re-deriving past work: when the user refers to earlier sessions or decisions, before debugging an error, and before implementing something that may already exist. It searches this machine's own history across every AI coding tool used on it, going back further than deja itself was installed. Before your first edit in a task, and again before you call a change done, ready or safe to merge, call deja with mode recall and the task's key nouns (file, package, feature, setting). A rule, a rejected option or a check it returns outranks your defaults: follow it and say so in one line. Two triggers are easy to miss because they are not questions: - The user states that something of theirs already exists and you have no record of it — "I already have X", "we use Y for this", "that's what Z is for". They are not asking; they are telling you the history exists, which is a stronger reason to search than a question is. …

How to install
mdr add vshulcz/deja-vu/deja-history@sha256:b695cce4baf15a12The line at the top of this page pins the label git:20261015.154ecf9, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
