Use whenever the user asks a question that prior work might already have answered — "what did we decide about X", "when did we ship X", "why did we choose X over Y", "has this failed before", "where did we put X" — and generally to ground answers in The Lossless Group's own corpus instead of training-data folklore. Encodes the four local Chroma collections (`context-vigilance-corpus`, `lossless-changelog`, `claude-code-sessions`, `claude-code-tool-traces`) reachable via the `chroma` MCP…
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 the Lossless Corpus The Lossless Group keeps a living corpus of its own decisions, shipped work, prior sessions, and tool-failure history in a **local Chroma database** wired into Claude Code via the `chroma` MCP server. Most questions a user asks about *prior work* can be answered from this corpus rather than training data. **Don't paraphrase from training data when the corpus could answer.** This skill is the discipline that makes the corpus load-bearing. Without it, Chroma sits there full of high-signal records that nobody queries. With it, every "what did we decide about X" question becomes grounded recall — with citations the user can verify in seconds. ## When to use this skill Trigger when the user's question takes any of these shapes: - **Decisions** — *"what did we decide about X"*, *"why did we choose X over Y"*, *"what's our stance on X"* - **Shipping** — *"when did we ship X"*, *"what shipped in May"*, *"did we already do X"* - **History** — *"what did we talk about last week"*, *"in a prior session we…"*, *"resume where we left off on X"* - **Failures** — *"has this errored before"*, *"how did we fix X last time"*, *"when did Bash with git rebase fail"* …

How to install
mdr add lossless-group/lossless-agent-skills/search-lossless-corpus@sha256:bbb787788bc10d74The line at the top of this page pins the label git:20260512.885ab36, 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.
